I - The dispenser of sterilizing products
This device, object of the present invention, has the function of pouring, into a quantity of raw water - or any other liquid - a well-defined weight or volume of sterilizing products, in order to achieve the complete elimination of all living traces of pathogenic microorganisms, plant or animal including viruses and bacteria, which it is likely to contain.

The dispenser consists of four main parts namely
1) - The tank fig. 4 (14) for storing products
sterilants.

 2) - The calibrated product reservoir fig.12 (119).

 3) - The product ejection system fig. 4 (1) (5) (27).

 4) -the recharging system fig. (17) (20) (26).

 Figures 4 to 20 show a complete dispenser, without any limiting character as to the dimensions or the manufacturing materials used.

1) - The storage tank for sterilizing products.

 The tank fig. 4 (14), object of the present invention, is made of stainless steel, or any other material resistant to chemicals.

 It is of parallel or cylindrical shape and has, on one face or a generator, a current level mark fig. 4 (18).

 Its bottom has a special drain fig.4 (15), which fits in a housing fig.4. (37) do inverted frustoconical shape.

This plug fig.4 (15) has a flange (36), a passage hole fig.10 (38) for the shutter fig.4 (17) and a recess fig.10 (39) which is the seat of a
Flat seal fig. 4 (4) -.

 The lower part of this flange fig.4 (11) is threaded, Figures 4-9 and 10 (13) to ensure tightening on the flange fig.4 (11) -.

 This tank has fixing points fig.4 (24) which serve on the one hand to receive the frame fig4-11 (23) of the manual or magnetic operation (27) fig. 11 (139) and on the other hand, to fix the dispenser inside the cabinet.

2) - the calibrated tank for sterilizing products.

 This tank, fig. 4-13-14 (12), is made of glass or any other transparent material. It has a cylindrical shape fig.13-14 (12)> with two square edges fig.14.

(49) to receive two flat seals (50) at each end of the cylinder or, with two straight edges fig.15-16 (5î) to receive two seals (52) in the shape of "U" U -.

 It is calibrated in that its internal volume is linked to the qualities of a well-defined sterilizing product and to its degree of concentration. This volume corresponds to the exact quantity necessary for the perfect sterilization of the water - or any other liquid - contained in the tank with which it is coupled.

 This calibrated tank fig. 4 (12) is locked between two flanges fig. 4 (7) (11) made of steel or any other resistant material - and these (7) (11) are held parallel to each other by four bolts long (9), screwed at (10) on the flange (11) and sliding at (8) in the flange (7) -.

 The bowl (12) and flanges (7) - (11) assembly is secured to the drain (15) by tightening the common threaded parts fig. 4-10 (13) and fig. 17-18 (13) -.

 Sealing is ensured by tightening by two flat seals fi.4 (16), arranged on either side of the bottom of the tank (14).

 Each dispenser is delivered with a set of tanks (12) of different diameters and corresponding seals.

 The lower flange fis: 9 (7) has, on its upper face, a corresponding number of concentric engravings (55), the utility of which is to allow correct positioning when the tank has to be changed.

3) - The ejection system.

A single press - which breaks down into two stages on the lever fig. 11-12 (27) (48), allows the dose of sterilizing products contained in the reservoir fig. :
1st step: When the assembly Fig. 11-12 (48) (27) (45) is pivoted downwards, it drives in its rotation, the axis (40) of which it is integral by locking the needle screws (46), as well as the ring fig. 12 (42).

 This ring (42), also secured to the axis (40) by the needle screw (46), compresses, by pivoting, the spring fig. 12 (43) which it holds captive at one of its ends in the notch fi. 13 (165).

 In turn, the spring (45), compressed, presses on the pallet fig.11-12 (26).

 This pallet (26) is a non-deformable part. One of its ends is wound around the axis (40) and pivots freely around it between two washers fig.12 (44). The other end, flat; is cut out fig. 12 (26) in the shape of a "U" to move without constraint, from top to bottom and from bottom to top, on both sides of the axis (1).

 Compressed therefore, this pallet (26), lowers in its rotational movement around the axis (40), the bowl fia.11 (166) and at the same time, also pushes down the tube fig. 4-11 (20) to which it is welded.

 However, at the other end of this tube (20) is screwed the shutter fig.4 (17) which then comes to bear on the seal fig.4 (4) and the seat fig.4 (3C).

 The passage to the sterilizing product from the tank to the reservoir (12) therefore becomes impossible.

 The bowl fig. 4-11 (167) has the role of serving as a housing at the base of the spring fig. 4-11 (21). It has in its center an orifice with a diameter greater than that of the tube fig.4 (20) so that it can slide without difficulty.

 2nd time, Always in the same movement which consists in pushing down the levior fig.11 (48), the finger fig.11-12 (47) meets the bowl fig. 4-11-12 (19) screwed fig.4 (28) at the head of the axis fig.4 (1).

 Upon contact, the axis (1) descends and the shutter fig. 4 (3) located at the other end of this same axis, leaves its seat fig. 4-19-20 (54).

 The sterilizing liquid contained in the reservoir (12) can then descend by gravity passing through the grooves fig. 5 (33) of the shutter fig. 4 (3).

 To accelerate the flow of the product, the shutter (5), moving away from its seat (54), reveals the mouth of the tube fig. 4 (5 :) which allows the arrival of air above of the product stored in the tank of (12).

 The role of fig. 4-11 (168) is to serve as a housing at the base of the spring (22). It has in its center an orifice with a diameter greater than that of the axis (1) so that it can slide without difficulty.

40- The recharging system.

It also breaks down into two stages
1st step: By eliminating any effort on the lever fig. 11-12 (27), the finger (47) goes back up, allowing the spring (22) to lift the bowl (19). This then drives upwards, the axis (i) with which it is integral.

 This upward movement is interrupted when the shutter (3) has returned to its place on its seat (549.

The outlet from the reservoir (12) is then locked. The same is true for the air intake tube fig. 4 (53), the outlet of which is blocked by the seal (4).

 2nd step: The spring fig. 4 (21) which is no longer compressed by the pallet (26) also pushes upwards, its seat, the bowl (166). However, as the latter is integral with the tube (20), the latter rises up inside the tank (14) moving away from its seat (39), the shutter (17).

 The liquid contained in the tank (14) can then descend through the canelurea fig. 7-8 (34) provided in the guide (33) of the shutter fig.7-8 (17) and refill the tank (12) -.

 This shutter (17) has in its center an orifice which, in its upper part is threaded (32) to receive, by screwing, the tube fig.4 (20).

 It is smooth, in its lower part fig. 7-8 (35) to allow the axis fig.4 (1) to slide freely.

 As for the ejection shutter fig. 5-6 (3), the loading fig. 7-8 (17) comprises a guide (33) and four or more passages (54) so that the liquid descends by gravity from the tank (14) into the reservoir (12).

 The advantage of this process is that each operation can only be done if the reverse operation has been executed and that commanded by one and the same movement two operations cannot occur at the same time.

 The flange fig. 4 (7) has a terminal (136) for the equipotential bonding.

 Optionally, a current magnetic control can (139) can replace the manual lever # i # .11 (48) -.

The Liguide- irradiation room
This device, object of the present invention, has the utility and function of allowing exposure to ultraviolet radiation - having a wavelength at about 2,540 Angstroms - raw water - or any other liquid
and this, in order to destroy all the pathogenic microorganisms it may contain.

 FIGS. 21 to 28 show a complete irradiation chamber, without any limiting character as to the dimensions or the manufacturing materials used.

The irradiation chamber consists of the following four main parts
1) - The external enclosure.

 2) - The radiation fields and their supports.

 3) - The supports of ultraviolet light lamps.

 4) - Field supply and drain circuits.

j) The external enclosure
This room, object of the present invention, is in the form of a small, completely airtight cabinet comprising
- A door fig. 23 (71) sealed on the front face; this is reinforced in the middle by an omega profile and receives, at the height of each field fig. 21 (57) a look fig. 23 (194) which consists, on the inside, of a frame of three sides fig. (195), receiving a movable protective glass and on the outside, a cover fig. 23 (196) pivoting, allowing the monitoring of the corresponding field.

 The four edges of this door have the shape of a "U" fig23 (73) with a seal. These edges are pierced with holes which allow the hermetic fixing, by bolts and assembly nuts, of the door on all its periphery with the four longitudinal faces of the cabinet fig. # 6) -.

 -The 8 lateral sides, fig.22-23 (70) internally receive parts fig.21-26 (58) in the form of "Z" intended.

to support the fields fig. 21 (57). These sides (70) present on the front, a double-fold profile fig. 23 (72) pierced with holes, for assembly, by bolts and nuts, with the door fig. 23 (71).

 -The rear face, # fig.22 (69) is electrically welded or screwed in a very tight way with the other four longitudinal faces.

It receives the plates fig. 22-24 (68) fixed by screws along the axes fig. 24 (76) .On these plates are all the fasteners of the supports fig. 21 (60) of
Lamps emitting UV-C radiation and fields (59).

 This rear face also includes, at each strip fig. 21 (61) socket holder (62), a sealed terminal fig. 22 (138) with contacts for common VTF lugs, allowing the connection between the UVO lamps fig. 21 24 (74) located along the axes fig.21 (63) and the ballasts and starters grouped in the compartment fig.2 (114) says: "Electrical equipment n -.

 -The bottom (179)) welded or screwed hermetically with the rear face and the sides, - receives the collector fig. 21 (65) for the outlet of the irradiated liquid as well as the outlet (177) for the drain manifold.

 The bottom also receives a level (107), current, because it is essential that the fields work horizontally in the direction of their length.

 To ensure this horizontability, the bottom, fig. 21 (179) is equipped with four legs fig. 21 (67) of variable height; The field level should be adjusted when the cabinet is permanently in place.

2) - The irradiation chaos and their supports
These parts fig. 21 to 28, object of the present invention have the function of spreading a film of water - u any other liquid - fig. 28 (82) laminar fig. 28 (83) (84) (85? (86) and ( 87) by brewing it between baffles Fig. 24-25-28 (81) and this, at a very short distance from the lamps emitting ultraviolet radiation C-260nm.

A radiation field consists of three main parts
- The collector: fig. 21-24-26 (77), it is the part in the field which receives the liquid before its horizontal dispersion: it is a cavity (77) which makes the entire width of the field. It is supplied with liquid, ie, by the weir fig. 21 (80) of the inlet tank fig. 21 (64) or, for the weir fig. 26 (80) of the upper field.

 The ccllecteur includes a distributor fig.26-27 (78) in the form of slots and whose utility is to divide the liquid uniformly before its passage between the baffles fig.26-27-28 (81) -.

 - The field: proper fig.21 and 24 to 28 (57) is a flat surface, slightly inclined from the collector towards the weir fig.21 (77) and (80) -.

 It has two raised edges (79) to avoid overflows. Its upper part is occupied by baffles fig. 26-27-2e (81) which are in the form of prisms, truncated at the two ends # of any other form. these asperities are arranged in staggered rows (81).

 The usefulness of this relief is on the one hand, to constantly divide the films of water - or any other liquid - Fig (82) and (83) i (87), therefore to mix them and on the other hand, to retain, for a longer exposure, the lowest films (86) - (87), those which receive radiation attenuated by the absorption of the upper layers.

 All these baffles (81) must emerge very weakly from the liquid indeed, it is for the user, the proof of the horizontality of the fields therefore of its maximum yield and, this also obliges the highest fluid blades fig. 28 (84) (83) to deviate their trajectory b each row of prism-.

 - The weir: fig. 26 (80) This part of the field is used to guide. without splashing, the liquid exposed, from one field to another by gravity.

 50n lower end also dips slightly in the liquid contained in the collector of the lower field, fig. 26 (77) - (80) -.

 Between the flat part of the field (5-7) and the weir (805 is located the regulator fig. 26 (88) in the form of slots.

It (88) aims to maintain the desired level on the field (57) and to standardize the thickness of the liquid film flowing through the weir.

- Field supports: For reasons of ease of maintenance, the fields (57) are simply placed on flower supports fig. 21 (58) and (59) which are of two types
The first, fig.21-26 (58) is a "Z" shaped profile, integral with the side faces fig. 22 (70) -. It follows the external shape of the bottom of the collector (77), which keeps the field (57) against the wall (70) and immobilizes it in the transverse direction. This "Z" profile supports the field on the 4 / 5th of its length and this, to allow, at the rear of the chamber, the connections of the fig.21 (176) nozzles and drain pipes (181).

 The second, fig. 24-25 (59) is a round bar of small diameter, secured to the plate fig. 24 (68) screwed (70) on the rear face (69) of the chamber.

 This support (59) which maintains the field (57) in a determined position relative to the lamps (74), comprises two fixed rings fig. 24-25 (75), located on either side of the field and which immobilizes it in the longitudinal direction.

3) - The supports for germicidal lamps.

 These parts, object of the present invention have for jute to receive and maintain the lamps Fig. 21 25 (74) emitting ultraviolet radiation, a constant distance above the fields (57) from which they are independent, fig. 21 (60) (61) -.

 Figures 21 - 22 - 24 and 25 show a complete system of removable supports which hold the lamps (74) above the fields (57), they are not in any way limiting as to the dimensions or the manufacturing materials used.

These supports have two main parts
- The fixed part, fig. 21 (60) consists of two sections made integral by welding or gluing. One, in the shape of a very flat omega, rests on the second in the shape of a "T". This assembly is supported at one of its ends on the rear face side (69) on the plate (68) integral with the rear face (69).

 This assembly fig. 21 (60) is the support and guide 13 of the movable part (61).

 - The mobile part, fig. 21 - 22 (61) is a profiled part in the form of a truncated and inverted prism. It is the base which receives the sockets fig. 21-24-25 (62) lamp back supports (74).

 This base (61) is also the housing for the electric supply of the lamps, supply which takes place via the watertight terminals fig. 21-22 (138).

45- The supply of the licuide and the song vacuum:
The arrival of raw water - or any other liquid in the irradiation chamber is controlled by a solenoid valve, located upstream of it and which is controlled by a current float-contactor, placed inside the tank fig. 2 (109) for storing sterilized water.

On reaching the low point, this contact float on causes three simultaneous operations, namely
- The opening of the solenoid valve circuit, located downstream of the manifold fig. 21 (177) for evacuation, which regulates the emptying of the chamber.

 - The closing of the electrical supply circuit of the germicidal lamps fig. 24-25 (74) and the light and sound control systems thereof.

 - The closing of the supply circuit of the solenoid valve located upstream of the chamber fig.21 (56) of irradiation, which regulates the arrival of raw water in the tank fig.21 (64).

 However, the liquid for reconstituting the tank reserve (109) will have to travel through the fields at a very precise speed. A pressure regulator is therefore provided upstream of the chamber but, after the solenoid valve.

 The liquid arriving in the irradiation chamber at a constant speed, will be received by the tray fig. 21 (64) supply -.

This is a small tank which consists of the following four elements
- A current device fig. 22 (175) -, exterior,
of connection.

- A tank fig. 21 (64) having the length, the width
of the field and comprising a background (171) and two counties
uneven. One, (172) above, ending with a
counter-fold is screwed to the ceiling of the chamber (56).

 The other, (173) below, receives the weir (80).

- In this small tank (64) is arranged a
diffuser fig. 21 (174) inside which ends
the rs brsnchemer.t device (175). This
diffuser is a tube immersed in the tank and
same length. Its lower generator has
orifices fig. 21 (170) close together, and arranged
slzr its entire length.

These orifices have the role of regularizing and
form the liquid flow over the entire length
from the tank (64) and avoid also;
s and splashes.

- A weir (80), the same length as the tank (68)
ensures the flow of liquid to the collector
(77) of the upper field of the chamber.

 Each field feeds the lower field via its own weir, and is supplied by its own collector.

 The treated liquid, having traversed by gravity, all the irradiation fields of the chamber, arrives in the outlet collector fig. 21 (65) from where it leaves towards the storage tank fig. 2 (109), by the strain Fig. 21 (66) -.

In working order, when the storage tank (109) is filled, the contactor float reaching the high point also causes three simultaneous operations, but opposite to those set out on page 10, namely
- The opening of the regulating solenoid valve circuit
the liquid supply to the chamber.

- The opening of the lamp supply circuit
germicides.

- The closing of the power supply circuit-
valve which regulates the emptying of the chamber.

 Thus, with regard to the liquid contained in the tank (64), on the fields (57) and in the collectors (77), the opening of the solenoid valve located on the evacuation circuit, will ensure the instantaneous emptying, therefore drying, of all the above-mentioned parts.

 These dry zones are intended to avoid that, when stopped, the germicidal lamps extinguished, pathogenic micro-organisms invade, gradually, the fields and their collectors and thus reach the tank (109 ) storage.

 The feed tank fig. 21 (64) therefore has at its bottom (171) a nozzle fig. 21 (176) with screw connection and barbed end for fitting a tube fig. 21 (181) ordinary flexible evacuation.

 Each collector is provided with the same tap (176) with screw connection and barbed end fitted with a tube (181! Ordinary flexible.

 All these flexible drain tubes (181) end in a single outlet fig. 21 (177) manifold, located on the bottom (179) of the chamber (56) -.

 This drainage circuit leads, like the others, to a special siphon fig. 52 to 57 (180) -.

III - The air sterilizer event.

 This part, object of the present invention has the function of filtering and sterilizing the air which is called in the tank fig. 2 (109) or in the dosers fig. 32 and 41 each time there is drawing of liquid.

 Figures 29 - 30 and 31, represent a complete advent, without any limiting character as to the dimensions or the manufacturing materials used.

This sterilizer vent fig. 29 (90) consists of five essential parts - namely
1) -The initial vent. Fig. 30 (91) -.

 2) -The connecting duct (93) -.

 3) -The secondary element (s) (92) -.

 4) -Electrical equipment (100) to (105) -.

 5) -The cradle (106) -.

1) - The initial vent: It is a cylindrical part fig. 29-30.

(98), open at one end - the air inlet - and closed at the other.

 This air inlet includes a fixed half-sleeve fig. 29-30 (98), internally threaded and a removable pad (96), as well as a changeable filter cartridge.

 the other end of the initial element (91) is closed by a last, sleeve (98), fixed, internally threaded onto which, a plug (96), removable and waterproof, is screwed. On this half-sleeve (98) is disposed an outlet nozzle fig. 31 (95), intended to receive the conduit (93) for connection. This half-sleeve also receives two couples fig. 31 (104) (105) of sealed terminals for the supply of the lamp emitting ultraviolet radiation, contained in the body of the cylinder (91) (o 2) - The connection conduit: 2) - The connection conduit: C 'is a part fig.29 (93) which allows a series mounting of two or more elements (91) - (92) from the initial element.

 This conduit (93), terminated at its two ends by bends at 900 (94), is fitted into the piquas (95) of the two elements which it joins. The assembly is done by welding or gluing.

3) - The secondary element (s): These are parts fig. 29 (92) identical to the initial element (91) but closed at both ends and therefore comprising no filter or sieve. The half-sleeves located at the estre: nit # s of these secondary elements are provided with a connection (S5) for connection to receive the connecting conduit (93) -.

 The last of the secondary elements is connected directly to the tank fig. 2 (îoc) by the tapping (95) which remains free.

4) - The electrical equipment: This is identical for all the elements and consists of
- A lamp fig. 30-31 (100) emitting ultraviolet radiation. This is positioned between two common sockets 30-31102) fixed on a special strip (101) in the shape of a "U
- A pallet fig.31 (1o1) and its two guides (137) cui have the role of maintaining it over the entire length of the cylinder while allowing it to slide outwards to allow the quick exchange of the lamp .

 The strip also serves as a support for the lamp supply wires and receives the terminal (136) for the equipotential bonding.

- Two pairs of terminals (104) (105), watertight with protective cover, provide the connections for starting and powering from the choke and the ballast, both grouped in the compartment fig. 3 (114): electrical equipment

in a region considered.

The dispensing dispenser, object of the present invention meets this need
Figures 32 and 33 show a complete dispenser dispenser, without any limiting nature as to the dimensions or the manufacturing materials used.

This device consists of three main parts namely
n The tank,
2) - The flanges -.

 3) - The drawing device -.

1) - The tank: This part is a cylinder fig. 32 (125), in transparent material, graduated according to a generator, in agreement with the local measuring unit.

 Positioned between two flanges (124), this cylinder is interchangeable and its volume can represent one or more times the local unit.

2) - The flanges: These round and flat fig.32 (124) parts have on their internal face one or several grooves fig.52 (126) circular, concentric whose diameters correspond to tanks having different volumes
The groove J which corresponds to the chosen reservoir, receives, on each flange, the ends of the cylinder which come to be encased therein. To seal, two
Flat seals are placed in each of the two grooves.

 These flanges (124) are tightened against the ends of the cylinder (125) and held by four or more bolts (127) and assembly nuts, arranged on the periphery of these fig. 33 (127).

 On the other hand, the upper flange has two tappings with elbows at 900, one fig. 32 (129) for the arrival of the liquid, the other (130), to allow the compensatory movements of air as well as the possible return of excess liquid to the tank (109) through the advent channel thus eliminating any risk of degradation due to overpressure downstream of the metering device.

 The upper flange is also pierced with two holes fig. 33 (128) for fixing the dispenser to a bracket.

 The lower flange has at its center a tapped hole fig. 32 (131), to receive, by screwing, the drawing device. -It (124) also has a terminal 1136) for the equipota # tielle- link.

3) - The draw-off device: This part includes a quick-opening tap fig.32 (132), screwed into the threaded hole (131) located in the center of the lower flange.

as well as the sieve, are intended to prevent flies and
especially wasps - hym * noptrz more than invading in hot countries - to land and contaminate this terminal part of the sterilized liquid delivery circuit * -.

VO The accessories:
The preparation of food for infants such as the making of baby bottles being one of the uses of sterilized water produced by the devices object of the present invention, we have planned to include - on option
under the worktop fig. 3 (110), a microwave oven
(119) of standard type for reheating these preparations.

The handling of these foods, to facilitate their passage into a heating or cooling enclosure, has led us to design specific accessories which are the subject of the present invention. Those are
1) - the ramekin rack.

 2) - The sliding bottle drawer.

 Figures 34 to 40 show the two complete accessories, without any limiting character as to the dimensions or the manufacturing materials used.

1) - The rameQuin locker. This part fig.34 (140) can be in Qeux di # Iérente ~, that of a rack with fixed trays or, that of a removable tray rack.

 - The locker with fixed trays is made up of a handle Fig. 34 (142) in the shape of an inverted TH

 Trays (141) in variable number, are welded or glued in the middle, perpendicular to the handle, at distances corresponding to the needs of the user.

Each tray has the longitudinal edges (189) raised and has, on the other two sides, notches
crates (190) which allow food packaging to be placed or grasped easily.

- The rack with removable trays is made up of the same parts as the previous one, but the trays have all
times the following features
To be fixed to the handle fig. 34-35-36 (142), the trays t141) each have two slangs fig. 36 (191)
riveted in the center of their two edges (189).

Each tray is set up by engaging one of
its two lugs (191) in an oval orifice fig. 35 (144) of the handle (142). The oval shape of the holes allows you to place
then, and at the same level, the opposite lug.

 To prevent the plates from pivoting around the pins (191), the sides of these receive a pair of plates fig. 34-3b (143), symmetrically arranged with respect to the pin, higher than the edges (141 ) and, spaced a distance slightly greater than the width of the handle fig. 35 (142) against which it rests, thus preventing any rotation of the plates.

The usefulness of this kind of calier is to allow
- Quick and safe handling of large numbers
food packaging such as raviers, pots,
ramekins, etc
- Cooking or reheating in a microwave oven.

 - Freezing of food products.

 - The stock in a cold or sterile room.

bracket, allows the equipotential bonding of
the appliance with the rest of the electrical installation.

4) - The measuring mechanism. It is located at the end of the stem fig. 43 (23a), facing the operator, and includes the following parts - A toothed wheel, calde on the axis fig. 43-44 (24a)
lever 25a and therefore always turns
in the same direction as this one (24a).

- A second axis fig. 43-44 (5ia) also mounted on the
bracket (23a), located in the same vertical plane as
the other axis (24a) but, placed above
- A small diameter idler gear (52a), wedged
on the second axis (51a) and tangent to the wheel (49a)

 - A fixed reading marker (55a).

4) - The pourer: This part, which is eccentric with respect to the vertical axis of the dispenser for reasons of convenience, is useful for clean and rapid filling of food packaging such as bottles, cups, etc. . -.

It is composed of the following parts
- A connection pipe fig. 42 (18a), on
the compression chamber (12a), bent at 900 -.

- The pourer's body (19a) which includes
inside
A sphere (20a) which acts as a shutter.

 An O-ring (32a), seat of the sphere (20a).

An adjustable pressure spring (33a) whose effect
is to maintain the sphere (20a) on its seat (33a).

outside s
The pourer's body (19a) has at its end
lower, a threaded part which allows to screw
more or less the beak (21a) and compress more or
minus the spring (33 a) which acts on the sphere (20a),
this in order to regulate the flow of the device.

- The spout (21a) has an external thread
to receive the stop (22a). Its end is
conical shape to receive a cap (134). The
outlet of the spout has a flush screen
removable, to prevent access to the tubing
wasps and other insects.

- The filling stop (22a) is a flat surface
and round comprising

tion thereof (22a) on the spout (21a).

An edge at 900 facing 19 down and on which is
attached the chain (135) which keeps within reach of the
hand flexible cap (134> -.

G) - The heating device
For the preparation of baby bottles in particular, the user must have water at a very precise and constant temperature.

It is therefore necessary to keep the temperature from the hot water generator at the same temperature and also to compensate for heat losses when the service is idling. To guarantee a uniform temperature, two additional devices are provided, namely
- Total insulation of the cylinder thanks to a coating
ment (39a) flow of pro polyurethane foam
covered by a resistant jacket (56a), formed of
two half-shells, made integral with the hatch
key (1a) by screwing them on the flange (85a)
aux auxboulons 34a) which assemble
of the cover (1a) and of the body (2a) of the cylinder.

- A coiled fig42 (40a) resistor
around the tank (11a) and the chamber (12a).

- A current thermostat, the bulb of which is placed at
the inside of the thermowell (41a) controls the resistance
tance (40a) and ensures the desired temperature.

Operating mode of the liquid dispenser:
Odor side:: It fills the assembly - tank (11a) and chamber (12a) using a push button or key switch and follows the rise of the liquid in the tank, thanks to the level indicator (42a).

After removing the cap (134) from the spout (21a), it places the bottle - or any other container against the stopper (22a)
It presses on the handle (26a) and follows the rotation of the vernier (54a) which scrolls past the fixed mark (55a).

 The display of the desired weight - or volume - having arrived opposite the fixed mark (55a), it releases the pressure exerted on the handle (26a), removes the bottle from the stop (22a), puts the cap back (134) on the pouring spout (-21a) if the next filling is not immediate then, stopper the bottle-.

Device side: The attendant, by acting on the push-button switch, triggered the following operations
1 - The closing of the supply circuit of the germicidal lamps located inside the vent (90) and the control lamps (Liquid leaving the tank (109), requires a corresponding volume of outside air, it is necessary imperatively sterilize the latter).

 The closure of the electrical circuit supplying the discharge pump located downstream of the tank (109), thus allowing the water stored in said tank to go up into the distributor (121).

 30- The closing of the solenoid valve circuit located between the discharge pump and the distributor. The other solenoid valves remaining closed, the one on the distributor's power supply opening, the water cannot help but arrive at this one.

4 - The sterilized water has therefore arrived in the tank (lia) which it has filled at the same time as the compression chamber (1? A) - By working in this direction, the check valve does not oppose any resistance
By filling the chamber (12a), the water expelled the air and raised the float (14a) which was placed on its conical seat (isba).

The level mark (42a) indicating to the operator that the tank is full, the latter stops pressing the switch and automatically triggers the reverse operations, namely:
- Stopping the repression polyp.

 - The extinction of germicidal lamps.

 - Switching off the control lamps.

 - Closing of the solenoid valve.

 5 - On the other hand, by pressing the handle (26a) the Operator has, by means of the lever (25a), raised the piston (27a) whose head (2ex) has deformed the membrane (9a) in pushing it upwards, causing an overpressure in the chamber (12a).

 This sudden increase in pressure compressed the float (14a) on its conical seat (16a) as well as the non-return valve (44a) by making them all the more tight as the pressure becomes stronger.

It is then the spring # 3a) which yields and leaves the sphere (20a) to move away from its seat (32a). #
The liquid flows as long as the pressure on the lever (25a) lasts - Up to 86 competition, however, by a full turn made by the vernier -.

 oo- As soon as the effort on the handle (26a) ceases, therefore, as the pressure falls, the sphere (20a) resumes its place under the thrust of the spring (33a).

 The membrane (9a) follows the head (28a) of the piston (27a) brought down by the return spring (5osa).

The depression created in the room, due to the return
in place of the membrane, causes the float (14a) to descend and frees the valve (44a) from all constraints.

 Part of the water stored in the tank (lia) aeacend fill the void and brings the float back on its seat.

 The device is ready for another bottle filling, all these operations are strictly aseptic.

 At the level of the mechanism for measuring the weights or the volumes, for the bottles in particular, it is necessary that the graduations of the vernier are as precise as possible therefore, that the entire perimeter of the drum (54a) scrolls past the mark (55a) and either occupied by a graduation from 20 to 240 Gr. or 1.

 To determine this graduation, consider the extreme positions occupied by the lever (25a).

10 When it is at rest, the point of tan
gence between the toothed wheel (49a) and the pinion
reference (52a) is located in hNn
2 - When the lever (25a) is fully depressed, the
second point of tangency between the same pieces
is in wL ".

 The return pinion (5Sa) and the drum (54a) being integral and wedged on the same axis (52a), the length of the arc EN will give the perimeter of the return pinion (52a) if it is desired that the drum (54a) - wearer of the vernier describes a complete turn when the handle (26a) traverses the entire place assigned to him.

 On the other hand, the vernier or the graduation displayed on the drum (54a) being a printed band and glued on it, it is easy to make it in different measurement systems as in different alphabets -.

vilo The hot water a8n8rator
In this device, the heating of water - or any other liquid - is done indirectly, thanks to a special fluid which acts as an intermediary.

 This fluid ensures the transfer of the heat energy produced by a current electrical resistance (72a) to the entire heating surface fig. 45 (64a).

This process has the following advantages
1- Water - or any other liquid - not being in direct contact with the heating elements of the resistance, ceases to be a cause of deterioration of these, either by its aggressiveness or, by its calcareous deposits.

 2c- Considering the mass of the fluid fig. 45 (63a), plus the metallic mass of the chamber (65a) and of the spiral (66a), the primary represents a significant "buffer" heat reserve which avoids, during close drawing, unpleasant temperature variations.

30 Given the shape of the screw fig. 45-46 (66a) which penetrates all the liquid - ~ the secondary - the transfer of heat is progressed-asif and the risks of untimely projection of vapor, at the opening of a tap, are no longer to fear
40- The water streams, moving in a spiral around the primary, are subjected to a significant turbulance and thus sweep to the maximum, the surface (64a) of heat exchange. The liquid is therefore intimately stirred thus ensuring regular, rapid and easily controllable heating.

 This device, object of the present invention, has the function of producing hot water - or any other liquid instantly - at a constant and very precise temperature.

 Figures 45 to 51 show a complete hot water generator, without limitation as to the dimensions or the materials used.

This hot water generator consists of two main parts namely
1 - The heating element.

 20- The liquid circuit.

1 - The heating element:
This element, fig. 45 - or primary - is made up of the following parts
a- The heating chamber which consists of
- The chamber proper Fig. 45 (63a) which is a hollow, cyllnaric volume, located inside the body hdlicoNdAl (65a), contains an organic fluid of paraffinic character; its role is to transmit the heat flow emitted by an electrical resistance to the entire heating body. On the other hand, to increase the amount of heat transferred by the wall fig.45-51 (88a) of the chamber, the latter (8Sa) has grooves fig.51 (89a) which double the surface.

These are notches (89a) which have for section equilateral triangles where we have the relation (90a) + (91a) - <92a) x 2
- The plug (67a) located on the front face of the heating chamber is fixed at the entrance of the latter (63a) on the body (65a) thanks to the threaded part (68a) common to the two places.

 This plug (67a) has a raised outer edge forming a flange fig. 45-49 (69a). This one (69a) is drilled every 60, with threaded holes fig. 45-49-50 (70a) to allow the fixing, by tightening of bolts, of the buffer fig. 45 (71a) on the plug (67a) and its flat seal.

 - A current electrical resistance, fig. 45 (72a) tix.-e on the cap (o7a) above its horizontal axis.

- A running finger (79a), intended to receive the bulb of the thermostat controlling the primary
A smoothing orifice (86S) for the introduction of the fluid into the chamber 63a), fig. 49-50-46 (86a).

b- An exo expansion device located at the other end of the chamber and which includes U A communication orifice fig. 45-48 (73a) between the chamber (63a) and the casing (75a) of the expansion device
A housing fig. 45-48 (75a), also containing fluid. This 5a) has a flange fig. 45-48 (e7a) pierced, every 60 #, with threaded holes (78a) for fixing the membrane fig. 45 (76a) and the flange (77a).

This casing (75a) is integral with the heating body (65a), thanks to the fixing bolts located in fig. 45-48 (74a).

 - A flange i'ig.45-47 (77a) with holes (78a) for the passage of the tightening bolts thereof (77a) on the housing (75a) -.

 - A fig45 membrane (76a) in flexible material, to allow, when deformed, to absorb the expansion of the fluid. This membrane (76a) is held firmly in place by tightening the flange (77a) on the casing (75a).

 This "membrane" system is effective as long as the temperature of the fluid does not exceed 100 to 110 C., sufficient level to obtain the secondary hot water necessary for the preparation of soups, freeze-dried drinks, baby bottles etc ... for example.

 However, to face particular cases, case where the fluid should be brought between 120 and 3400C. the diaphragm device "would be removed and the orifice (73a) plugged. The expansion of the fluid becoming much too large the expansion would then be absorbed by a conventional system comprising an expansion vessel under nitrogen whose circuit would be connected to a nozzle Fig. 49-50 (85a) placed on the plug (67a) of the heating chamber (63a).

 c- The element for transferring heat flow to the liquid.

The electrical energy dissipated in heat by the resistance fig.45 (72a), is found entirely in the assembly "body of the chamber - helical screw" (65a) (66a)
It is this last part of the primary which is immersed in the liquid to be heated - the secondary circuit and it is the two faces fig. 45 (64a) of this helical screw which diffuse the heat flow in the liquid.

 The design of this part (66a) which occupies the entire shell, solved the problems of its own expansion. Indeed, the assembly fig. 45 (63a) (65a) (66a) has only one point of attachment, that is the part screwed onto the plug (t7a).

 The other end is free, so there is nothing to prevent the elongation of the entire heating element.

 As for transverse expansion, the hddicolal screw (66a) having an outside diameter slightly smaller than the outside diameter of the ferrule (56a), there is no risk of deformation there. On the other hand, the little liquid that can pass from one step to another, is not harmful.

 For the heating of certain very aggressive liquids the assembly (65a) (66a) can be made of graphite, or, if the assembly is made of metal, it can also be covered and protected by a common non-stick coating and this, to facilitate the maintenance of this organ.

20 The liquid circuit
It is the course followed r the liquid to be heated or, secondary circuit. The water or any other liquid, entering the tank (56a) by means of the nozzle 45 (60a), travels through the entire developed part of the h licodal screw and leaves through the nozzle (61a).

The main parts that make up this circuit are:
The tank which includes:
a) - A ferrule fig. 45 (56a), closed on the arrival side by

VIIIo-The siehon:
It is a device where ends
- The overflow of the tank fig. 2 (109).

 - The collector fig. 21 (177) of room (56).

 It must be particularly effective, taking into account the dangers of contamination that an septic opening to the outside presents, when the pipes are to be sterile.

 The siphon (180), object of the present invention, eliminates these risks.

 Figures 52 to 57, represent a complete siphon, without limitation in terms of dimensions or materials ~ - rials used.

This siphon (180) consists of the following parts
1) - The bottom, fig. 53-55-56 (97a) is square or rectangular depending on the model.

 The part of the mower (97a) which is located under the compartment fig. 56 (116a), comprises a deformation (111a) forming a funnel which ends in a sleeve (112a) from which the connection can be made either in the direction a recovery tank - in a region poor in water - or, on a simple draining.

 2) - e sides fig. 54-56- (106a) and (107a), they are four, terminated in their lower and upper part by a return towards the outside, forming a frame fig. 54-56 (11Ia) and (114a). These are drilled with holes fig.52-54 (110a) intended for the passage of the assembly bolts with the bottom (97a) and the cover (109a) -.

3) -; the interior of the siphon is divided into three separate compartments to have:
a) - The inlet compartment fig. 53-54 (98a), is delimited by the partitions fig. 54 (100a) and (105a) as well as by the sides (106a) and (107a).

 It includes (98a) the first weir fig. 55 (101a) at the height of which, on the compartment side, stagnates the liquid.

 It receives the dip tube fig. 55-56 (i03a), arrival of emptying and overflows.

 b) - The intermediate compartment fig. 54-56 (99a) is delimited by the partitions fig, 54-56 (105a) and (115a) as well as by the side (107a) and the two parts of the opposite sides (106a) fig.52-54-.

 It is divided into two by the settling wall fig. 56 (100a) -. The latter, comprising at its base a passage hatch (120a), connects the two parts of the compartment (99a) from below.

 This compartment t9, a) comprises the second weir fig. 54-56 (118a) at the height of which, compartment side (99a), stagnates the liquid.

 c) - The outlet compartment fig. 54-56 (116a) is delimited by the partitions (100a) and (115a as well as by the sides (106a) and (107a).

 The latter (116a) is dry because, the liquid 9 falling, intermittently, from the weir (118a), only passes through it; this compartment contains a cartridge fig. 5356 (117a) composed of synthetic fibers - therefore imputrésciblas, held between two fine but rigid sieves.

 These two sieves, like the tangled fibers that they stabilize, have the purpose of preventing access to the two preceding compartments for all types of insects often carrying micro-gold # pathogenic anisms.

 4) - The overflows. Fig. 55-56-57 (101a) and (118a) are parts which are an integral part of the partitions and which are intended to make any contact between two impossible by dripping or splashing compartments.

 The flow bed fig. 57 (122) delimits, on the side of the compartment (98a), the height fig. 57 (123a) of the liquid level. The slope of the bed (122a) means that it does not reject liquid on its surface.

 The front part of the spillway, in the form of a teardrop fig. 57 (102a) as well as the sides (121a), prevent the liquid, during a normal overflow, from running in any way along the wall (105a) and thus create a wet connection between two tanks, even momentary. Any microbial progression against the current is therefore excluded.

5) - The cover, fig. 52-53-55 (109a). It is a flat piece which covers the three compartments of the siphon and ensures its sealing by compressing, on the upper frame (114a) a seal fig, 53 (108a),
The tightening on the frame (114a) is obtained thanks to the assembly bolts arranged in the holes (110a).

The cover (109a), comprises above the compartment (98a) an orifice for the passage of the tube (103a) collecting the drain water, and receives, screwed, the base fig52 (104a), of the tube (103a) and its seal. This base (104a) is welded to the dip tube (103a) -.
