  • the proportioning installation shown in the figures comprises a stand 1 which, by means of posts 2, bears a supporting plate 3 for the vessels 4.
  • Each vessel 4 is connected by a pipe 5, in which is arranged a cock 7 which is controlled by a grip 6, to a level control which comprises a small tank 8.
  • the pipe 5 opens at the top through an opening 9 into the small tank 8. Even though the small tank 8 is substantially completely closed, the inside thereof is however under the atmospheric pressure, as the bent pipe 10 forms a connection between the tank inside and the ambient air.
  • Each vessel is sealed by a stopper 11.
  • a small pipe 12 which enters into the liquid up to an adjustable level, passes through the stopper 11.
  • the unit formed by the vessel 4, the small pipe 12, the pipe 5 and the small tank 8 insures maintaining of the level inside the small tank 8.
  • a siphon 13 is supplied from the small tank 8 in which the liquid level is maintained constant and feeds the liquid through the cock 14 towards the pipe 15 which is divided into four small pipes 16.
  • each pipe 15 lies, at the height 61, solenoid operated valve 61a.
  • Each small pipe 16 opens over a mouth 17 which is clamped in a supporting element 18 which may itself be adjusted in the height position thereof proportioning installation proportioning installation proportioning installation in a way which is not shown in the drawings, so as to take into account the height of the test-tubes 19 into which the liquid must flow.
  • the test-tubes 19 are supported by a carriage 20 which is provided with wheels 20a received in oppositely facing inclined trackways 21 formed in vertical side members 22a of slide 22.
  • Carriage 20 moves in the direction of arrow 23 in a stepped, controlled manner by the force of gravity controlled by pawl 54 cooperating with notches 55 formed in the bottom edges of vertical frame members 2012 of carriage 29.
  • a protruding cam or lug 22] attached to one member 22a closes successive switches 24; there being a separate switch 24 for each solenoid operated valve 61a.
  • the slide 22 is not fixed but rather adjustable with respect to the stand 1. To a determined position of the slide 22, corresponds a particular closure of a switch 24 which cooperates with the coil 25 of a solenoid operated valve 61a.
  • the details of this magnetic valve which are known by themselves, have not been described. To understand the installation, one only has to reckon that when a coil such as shown at 25 in FIG. 6, is supplied the solenoid operated valve 61a is open and when the coil 25 is dead, the magnetic valve is closed by a spring (not shown).
  • the closure of a particular switch 24 determines which one of the magnetic valves may be opened at the height 61 and this is determined by the slide position, in a way which is not shown in the drawings.
  • a cam in the slide causes the closure of a switch, in such a way that in each one of the eight positions of the slide, another switch is closed each time.
  • the installation is supplied from an alternating current network 26 and it is powered by closure of the switch 27.
  • the closure of the switch 27 causes automatically the synchronous motor 28 to run and supplies the rectifier 29.
  • the motor 28 is mounted on a support bracket 28a attached to the bottom edges of slide members 22a.
  • the motor 28 drives the magnetic coupling 31, which in turn moves the lever 32 in the direction of arrow 33.
  • a spring 34 seeks to pull down the arm 32, that is opposite the direction of arrow 33.
  • Spring 34 is attached at one end to screw 35 in motor support bracket 28a and in hole 36 in lever 32 at the other end. In the same way the motor 28, the magnetic coupling 31 and the lever 32 are mounted on the slide 22.
  • knob 37 which is adjustable in the stand 1.
  • the knobs 37 can be moved vertically in slots 37a of a panel 37b that encloses the motor and slide mechanism. Scale indicia on said panel between said slots aid in positioning knobs 37 as required.
  • the slide may lie in eight different working positions and in each one thereof the end of lever 32 is located in front of another knob 37.
  • the various knobs 37 are adjusted by taking into account the desired opening duration of the solenoid valve 61a which is located on the pipe 15 that connects the mouths 17 to the small tank 8 which is supplied from a particular vessel 4.
  • a determined position of the slide causes, as stated above, the closure of one of the switches 24 and thus enables to open a particular solenoid valve 61a which is located in the pipe 15 of a vessel 4.
  • the lever 32 faces a particular knob 37 and this knob 37 must be adjusted at such a height that, when the installation is operating, the corresponding solenoid valve 61a remains open during a predetermined period of time. This period is dependent on the amount of liquid which must be lead to each test-tube, on the viscosity of said liquid and on the density thereof.
  • the lever 32 As the motor 28 runs and is connected mechanically to the magnetic coupling 31 which is powered, the lever 32 is moved from the rest position thereof on the knob 37 along the direction of arrow 33 until the lever 32 moves the switch 49 from the solid-line position of FIG. 6 to the broken-line position in the same figure.
  • the circuit of a coil 25, the corresponding switch 24 of which is closed due to the position of the slide 22, remains closed and this from the rectifier 29, through the switch 49, the coil 25, the switch 24, the switches 50, 47, 46 and 44, back to the rectifier 29.
  • the switches 44, 47 and 50 are indeed normally in the closed position shown in FIG. 6 and the switch 6 is in the closed position due to the powering of the coil of the relay 43.
  • the solenoid valve 61a Due to the powering of the coil 25, the solenoid valve 61a remains open. This valve returns to the closed position as soon as powering of the coil 25 is stopped, which is the case when the switch 49 leaves the position shown in solid lines in FIG. 6.
  • the lever 32 reaches the upper position thereof, after a period of time which is dependent on the rest position determined by the knob 37, the liquid supply from the vessel 4 towards the mouths 17 will stop. Simultaneously, the switch 49 will reach the broken-line position in FIG. 6, which causes powering of the circuit of coil 51. Powering of the coil 51 results in attracting the lever 52, which swivels about pivot pin 53 with respect to the slide 22.
  • the end 54 of the lever 52 is thus taken out of a notch 55 provided in the lower face of carriage 20.
  • the carriage 20 is thus not retained any more relative to the slide 22 and it may thus slide under its own weight along the inclined trackway 21, along the direction of the arrow 23 shown in FIG. 1.
  • the other end 56 of the lever 52 bears against the switch 47, in such a way that said switch is moved away from the closed position thereof, which cutsoff the electric circuit of the magnetic coupling 31 and switches the small yellow light off.
  • the lever 32 is not driven any more by the synchronous motor 28 and the lever 32 is returned by the spring 34 to the rest position thereof on the knob 37.
  • testtubes 19 of the first row were located underneath a given row of mouths 17.
  • the carriage 20 glides forward down the inclined tracks until the test tubes of the following row come underneath said given row of mouths 17.
  • These test-tubes receive the measured amount of liquid from the same vessel 4, after which the carriage 20 glides again further along on the tracks 21.
  • Switch 44 is characterized by having a long activating arm 44a which extends into the path of the forward wheel on one side of carriage 20 near the end of one inclined track 21. When the said wheel contacts the end of arm 44a, the circuit to solenoid 51 is opened and carriage 20 is stopped and held from further forward motion by pawl 54.
  • the carriage To be able to fill test-tubes again and to start a new cycle of operations by depressing the button 40, the carriage must be returned, with respect to the slide, to the initial position thereof, in such a way that the switch 44 is not retained any more by this carriage 20 in the solidline position of FIG. 6.
  • the displacement of the carriage may also be made possible independently of the automatic operation under the action of the magnetic coupling 31 is as described above.
  • the button 58 is depressed, the circuit of coil 51 is automatically closed, which results in the end 54 of the lever 52 being maintained out of engagement with the recesses 55 of the carriage 20, in such a way that the carriage can move freely under the action of gravity.
  • the switch 47 opens automatically in such a way that the liquid cannot flow in any way through the magnetic valve during the movement of carriage 20.
  • the button 58 thus enables a manual control of the carriage movement.
  • the carriage 20 may always be moved manually along the slide 22 in the direction opposite arrow 23, as the shape of the cam-like end 54 of lever 52 does not oppose this movement against the gravity action.
  • the switch 50 can be brought manually from the position shown in solid lines in FIG. 6 to the one shown in broken lines in the same figure. This results in cutting-off a coil 25 of a magnetic valve, according to the position selected for the slide 22. By adjusting the switch 50, it is then possible to let flow through the mouths 17 as much liquid as it is desired. This may for instance be desirable when one wishes to rinse the mouths and the pipes on which they are mounted. It is possible to use for this purpose a water-jet pump 59 which is operated by depressing the switch 60, which is also used for forcing air bubbles out.
  • the switch 30 is closed during the displacement, in such a way that the solenoid 62 is activated, causing arm 63, which is pivoted at 64 on motor support bracket 28a, to move upward and retain lever 32 up in the position shown in phantom lines in FIG. 5.
  • a magnetic valve which is located in the discharge pipe of a vessel may be conditioned to operate. This valve is thus actually opened during a period of time which is dependent on the height of the knob 37, each time that a row of testtubes 19 is brought underneath a row of mouths 17. As soon as the test-tubes 19 have received liquid during the selected period of time, the carriage 20 carrying the testtubes 19 moves until a following row of test-tubes 19 is brought underneath the same row of mouths 17 and this until all of the test-tubes 19 have finally received during the selected period of time, liquid from the vessel 4, the choice of which is dependent on the adjustment of the slide 22.
  • Switches 24 Normally opened, each being individually closed in response to the slide 22 attaining a predetermined position.
  • Coils 25 Each adapted to control a magnetic dispensing valve upon its corresponding switch 24 being closed.
  • Coil 31 Actuates the coil 25 corresponding to a switch 24 that is closed in response to the position of slide 22.
  • Switch 44 Moves to broken line in response to carriage reaching the end of its travel-opens switches 45 and 46 to deactuate coil 31.
  • said containers are in the form of test tubes arranged in a plurality of rows, each of which extends in a direction transverse to carriage movement; and wherein a plurality of months extend from each tank and are arranged in rows extending in a direction transverse to carriage movement, the distance between adjacent rows of said mouths corresponding to that between said test tubes.
  • said regulating means comprises an actuating arm pivotally mounted on said slide, means to move said arm through a cycle in response to a signal from said actuating means, said arm adapted to deactuate said valve means at the end of its cycle, and means to regulate the duration of said cycle.
  • valve means are in the form of solenoid operated valves provided with a coil; and wherein said control means comprises a switch, separately connected in series with a corresponding coil, and means responsive to the position of said slide to actuate one of said switches.
