Definitions

  • a tank for processing photographic materials has an opening which is closed with a movable cover provided with an inlet and outlet for water.
  • a hose is connectable with a source of water and a releasable connecting element connects the hose with the inlet in the cover.
  • the connecting element has a flow passage for the water and is at least in part transparent so that the interior of the passage can be observed. Also, the connecting element has a port which communicates with the flow passage and which can be partly or completely closed at the will of the user.
  • the present invention relates generally to a receptacle, and in particular to a receptacle for treating of photographic materials.
  • the cover has two or more openings of which one is an inlet opening for water which is to be introduced into the tank, and the other is an outlet opening for excess water.
  • the inlet opening is preferably but not necessarily located centrally in the cover and is connected with a hose or pipe which in turn communicates with a source of water.
  • This type of tank has a variety of possible applications, namely it can serve not only for watering of film or photographic materials but also for fixing and similar processing operations to be performed on photographic materials.
  • tanks of this general type eliminate the need for providing special tanks in which watering of photographic film strips would have to be carried out.
  • the known constructions have certain disadvantages. In particular it has been found that the watering times required for photographic strips are relatively long and are in excess of twenty minutes. Also, the formation of eddies by the water in the interior of the tank is still not as intense as desired, despite the reduction in the diameter of the inlet passage in the synthetic plastic connector which is intended to provide improved eddying.
  • Other disadvantages of the prior art include the fact that it is impossible to inspect the interior of the tank and that the level of the water in the tank cannot be determined in the region of the inlet opening.
  • An additional object of the invention is to provide such an improved construction in which the watering times required for the watering of photographic strip material are substantially reduced.
  • Still a further object of the invention is to provide such a construction in which the formation of eddies in the tank is promoted and increased.
  • a concomitant object of the invention is to provide such a construction in which the liquid or liquid level can be observed.
  • a receptacle particularly a tank for processing of photographic materials
  • a vessel having an opening and a removable cover for this opening, which is provided with an inlet and an outlet aperture.
  • a conduit is adapted to be connected with a source of liquid, and a connecting element is provided for connecting the conduitwith the inlet aperture.
  • the connecting element has a passage means communicating with the vessel and with the conduit and in accordance with the present invention it is provided with port means communicating with the passage means and being at least intermittently closable. Further, the connecting element is at least in part transparent for enabling viewing of the interior of the passage means.
  • a tank constructed in accordance with the present invention substantially reduces the required watering time, and tests which have been carried out have shown that watering times can be reduced to approximately 5 minutes as opposed to twenty minutes or more required in the priorart constructions. This assumes a water flow of approximately 4.5 liters per minute and a water temperature of approximately 15C.
  • the water flow through the tank can be precisely adjusted, being capable of control in an exact manner due to the fact that it can be observed as a result of the at least partial transparency of the connecting element.
  • the control itself is effected in very simple manner in that the port means is closed, for instance manually, so that the interior of the connecting element is no longer in communication with the ambient atmosphere.
  • the port means is opened and ambient air is again aspirated by the flowing water, so that an increased eddy current formation in the inlerior of the tank and thus an improved watering effectiveness are obtained.
  • the coupling or connecting element has a first or lower portion which is transparent and of tubular configuration, being dimensioned so that it can be inserted into the inlet opening of the cover.
  • it has a second or upper portion which can be connected with the filling hose or conduit and which is provided with a reduced diameter section through which the passage for the water extends, and which section can be inserted into the interior of the first portion.
  • the first portion is preferably in its entirety of a transparent and clear material, for instance synthetic plastic or glass, the flow of water can be properly observed at all times and a precise control of the water level by intermittent closing of the port means can be effected.
  • the first portion of the connecting element is provided with at least one indicium or marking, and according to a currently preferred concept two such markings will be provided which are spaced from one another and condigurated by annular grooves provided on the outer circumferential surface of the first portion, although they could also be provided on the inner circumferential surface bounding the flow passage.
  • the port means When the port means is temporarily closed, water is allowed to rise in the first portion until the water level is between the two markings and when this position is reached, the port means is opened. This indicates that a precisely predetermined quantity of water flows through the passage.
  • the markings can for instance be so located that a flow-through of approximately 4.5 liters of water per minute is obtained when the aforementioned water level is reached.
  • the port means is advantageously located in the immediate vacinity of the free axial end face of the first portion so that it is as far as possible removed from the water level which is to be selected in the first portion intermediate the markings.
  • FIG. 1 is a perspective view illustrating an arrangement of the present invention.
  • FIG. 4 is a perspective view of a detail of still another embodiment.
  • the receptacle or vessel itself is of known construction such as is utilized for watering tanks known from the art. It is made of a material, preferably synthetic plastic material, which is resistant to acids and the configuration of the tank itself can be selected in accordance with any of the known prior-art teachings as long as its removable cover is provided with two or more apertures.
  • the vessel or tank is generally identified with reference numeral 3, being composed of the actual cylindrical vessel 4 and a removable cover 5 which closes an open side of the vessel 4.
  • the cover 5 itself is provided with a centrally located inlet aperture 6 and laterally thereof with an outlet aperture 7 through which excess water is permitted to flow out.
  • FIG. 2 shows that the connecting element 8 has a first or lower portion 13 of which is of tubular confuguration and which is in the illustrated embodiment made in its entirety of a transparent (preferably clear) material, such as glass or advantageously as synthetic plastic material.
  • the end portion 14 of the first portion 13 is stepped for a decreased outer diameter, so that is can be readily inserted into the inlet opening 6 of the cover 5 until the shoulder 15 created by the stepped configuration abuts against the outer side of the cover 5.
  • the flow passage in the interior of the portion 13 is, however, of constant cross section throughout its length.
  • the outer circumferential surface of the portion 13 is provided with indicia here illustrated as two axially spaced annular grooves 16, and in the region of the upper or free end of the portion 13 there is provided a port 17 which communicates with the passage in the interior of the portion 13 and which can be intermittently closed, for instance by placing a finger of an operator over it.
  • the connecting element 8 further comprises a second or upper portion 18 which may be of a nontransparent or opaque material, for instance a synthetic plastic as illustrated, and which is so configurated that a reduced-diameter section 19 and also a part of the larger diameter section can be inserted into the interior of the portion 13 as illustrated.
  • a shoulder or flange 20 is provided which abuts against the free axial end face of the portion 13 to thereby limit the extent to which the portion 18 can be inserted into the portion 13 and provide for a precise positioning of the section 19 within the portion 13.
  • the flange 20 is here configurated as an annular flange but could of course have other configurations.
  • THe portions 13 and 18 may be connected unitarily with one another as by a suitable adhesive or the like, to be applied for example to the axial end face of the portion 13 and the flange 20 of the portion 18.
  • the portion 18 is provided with an axial flow passage 21 which constitutes a part of the overall flow passage composed of the passage 21 and the passage in the interior of the port 13.
  • the passage 21 is also of constant cross-section throughout its entire length, as is the passage in the portion 13.
  • the forward end of the section 19 extends somewhat beyond the mid-point of elongation of the portion 13, so that the water entering from the hose or conduit 9 via the passage 21 will not enter directly into the vessel 4 but will instead first enter into the passage in the interior of the portion 13, and from there into the vessel 4.
  • the flow of water can be precisely adjusted between the two grooves 16 by temporarily closing the port 17, for instance by placing a finger over it.
  • the adjusted level of the water is idnetified at reference numeral 22 in FIG. 1 and is obtained by closing the port 17 until the water rises to the lever 22.
  • this level the user knows that depending upon the location chosen for the markings 16 a quantity of for instance 4.5 liters of water per minute flows through the device, although this of course is only exemplary.
  • the port 17 is exposed again, the water aspirates air and carries it along, which results in the formation of increased eddies in the interior of the tank 3 and lhus provides for substantially improved watering (and shorter watering time) of photographic material in the tank 3.
  • portion 13 is circular in the illustrated embodiment. However, it will be appreciated that it can also be other-than-circular, or polygonal if desired, as seen in FIG. 5. Furthermore, the section of the passage in the portion 13 may continuously taper or converge in the direction towards tank 3 as shown in FIG. 3, and these measures may be realized for accommodating the construction to circumstances prevailing in a given application. Also, the number of indicia and/or that of the ports, as well as the particular type and configuration thereof, can be different from what has been illustrated.
