Definitions

  • a photographic processor formed by an outer chamber with an inner chamber supported therein having walls which are spaced from the walls of the outer chamber.
  • a cap seals both the inner and outer chambers and contains an opening through which liquid may be introduced into the inner chamber when the processor is upright. Openings are provided in the inner chamber adjacent the cap so that processing liquid may flow therethrough into the outer chamber when the processor is held horizontally and a liquid may subsequently flow therethrough and out through the opening in the cap when the processor is inverted.
  • a photographic lighttight processing chamber within which photographic sheet material to be processed may beintroduced-withthe sheet material lying close to the sidewall of the chamber, an aperture provided at the top' of the apparatus forthe introduction of processing v which the lid is fitted.
  • the aperture for introducing liquid also serves as the'discharge irrreans so that there is only one aperture.
  • the apparatus consists of a container and a removable lid for allowing sheet material to be introduced into the container, the said one aperture being provided in the lid.
  • the cup and lid may-be separate members, and the cup may be fitted into the apparatus before the lid is fitted, but the cup and lid are preferably interconnected so that the cup is detached from the apparatus when the lid is detached.
  • a lid fora photographic processing apparatus said lid being adapted to be fitted toan open topped container to form be processed was to achieve consistent therewith alighttight processing chamber within which photographic sheet material to be processed may be introduced with the sheet material lying close to the sidewall of the chamber, said lid having a cup connected to the under sideof the lid with the top of the cup nearest the under side of the lid, an aperture being provided in the lid through which liquid may be poured into the cup, said cup and aperture being so arranged 'and disposed that when the lid is fitted to an open-topped container and the apparatus is tilted from the vertical to a horizontal position liquid in the cup will be discharged'into the processing chamber and not out of the aperture, and discharge means for discharge of liquid from the apparatus upon said apparatus being turned upside down.
  • the cup is preferably connected to the lid by a plurality of spacers disposed between the underside ofthe lid and the upper cndof the cup.
  • the aperture may be funnel-shaped at its outer end.
  • the lid may be adapted to make engagement-with the container in any convenient way; for instance, it may be apush fit but preferably it screws on.
  • FIG. 1 shows a cross-sectional view of a processing apparatus
  • FIG. 2 shows a plan view of the 'lid for-the apparatus.
  • a photographic processing apparatus consists of a relatively long cylindrical tubular container 1 open at one end.
  • a circular lid 2 screws onto the open end of the container 1.
  • the lid is formed-in two parts 3, 4'which are screwed together.
  • the part 4 of the circular lid is thicker than the annular part 3 and projects outwardly fromthe lid 2.
  • An aperture 5 passes centrally thr'oughthe part .4 of the lid 2, and
  • the apparatus is then rotated until the process is complete.
  • the apparatus is then turned upside down and the liquid pours out of the aperture 5.
  • the apparatus can be filled with .water for washing,.or with the next processing liquid as required by the process in question.
  • the apparatus which would have required 1,000cc. of liquid to fill it in the conventional way requires only 25 cc.
  • the method of using the apparatus ensures that the material to be processed is evenly treated.
  • a photographic processing apparatus comprising outer container means having a top endand a bottom end, said mounted within said outer container means in spaced relationhe air-vent is preferably'in the form of vided in*the top end of said outer container means and communicating with the interior of said inner container means for the introduction of processing liquid thereto when said processing apparatus is in an upright position, said aperture being positioned in said top end so as to fall within the confines of said inner container means, and fluid passage means formed at the top of said inner container means adjacent the top end of said outer container means and communicating with said processing chamber, said fluid. passage means operating to permit processing fluid to flow into said processing chamber when said apparatus is tilted from an upright to a horizontal position and to permit fluid to flow from said processing chamber through said aperture when said apparatus is inverted.
  • a photographic processing apparatus as'claimedin claim '3 in which the inner container means and lid are interconnected.
  • the inner container means is formed by a cup connected to the lid by a pluralityof spacers disposed between the underside of the lid and the upper end of the cup.
  • an air vent for venting the interior of the processing apparatus, said air vent being in the form of a narrow tube extending into the cup.
  • a photographic processing apparatus comprising a substantially cylindrical housing for receiving photographic material to be processed, which housing is adapted for-movesaid housing and said received material while said housing is disposed generally vertically, and for discharging such liquids into contact with the cylindrical interior surface of said housing and said received material when said housing is disposed generally horizontally.
  • said reservoir means is a liquid container supported substantially coaxially within said housing below said opening when said housing is ina vertical orientation.
  • Photographic processing apparatus as in claim 9, wherein said container has at least a portion spaced from said opening and adapted to discharge such liquids upon tipping of said housing from said vertical orientation.
  • a photographic processing apparatus comprising 7 an outer container having a top end and a bottom end, said outer container being openable at one end to receive sheet material to be processed, an inner container mounted within said outer container in spaced relationship thereto to provide a processing chamber externally of said inner container and within said outer container, said inner container being operative tocontain fluid introduced therein, the top end of said outer container being provided with an aperture communicating with the interior of said inner container for permitting the introduction of processing liquid into said inner container through said aperture when said processing apparatus is in an upright position, and fluid passage means between said inner container and said processing chamber for permitting processing fluid contained in saidinner chamber to flow into said processing chamber when said'apparatus is tilted from an upright to a horizontal osition.
  • a photographicprocessing apparatus comprising a substantially cylindrical container for receiving photographic material to be processed,said container having a top end and a bottom end when in a vertical orientation, said container being adapted for'movement-between substantially vertical and horizontal orientations, and having an opening in said top end for the admission of processing liquids into said container, the improvement which comprises reservoir means mounted within the container directly beneath and in fluidcommunication with 'said opening for receiving liquids admitted through said opening and retaining said received liquids out of contact with the interior surface of said container and said received material while said container is maintained generally vertically, said reservoir means having means for discharging such liquids into contact with the cylindrical interior surface of said container and said received material when'said container is moved from a substantially vertical to a substantially horizontal orientation.
