Title: Photographic film unit
IPC: G03D9/02
Filed: 1964-06-05
Abstract: 1,026,096. Photographic film units. INTERNATIONAL POLAROID CORPORATION. June 5, 1964 [June 14, 1963; Sept. 19,1963], No. 23438/64. Heading G2A. A photographic unit comprises a first (photosensitive) sheet and a second (print-receiving) sheet, with a rupturable container of processing liquid disposed so as to be between the leading edges of the sheets when they are in contact, and a layer of acidic material disposed so as to be between the trailing edges of the said sheets for absorbing excess processing liquid. As shown, each film unit comprises a photosensitive sheet 12 and a print-receiving sheet 14. A leader sheet 16 is attached to the leading edge of sheet 12, and carries the rupturable container 22 of processing liquid, which is in general of a strongly alkaline nature. Receiving sheet 14 is mounted on a carrier sheet 24 having a tapered leading end 32 which is secured to the corresponding tapered leading end 20 of  leader sheet 16. Tapered leading sections 20 and 32 together form the leading end of the unit as a whole. Side guides 33 are secured along the edges of carrier sheet 24 to act as spacers between sheets 12 and 14 and also to retain the processing liquid. At the trailing edge of sheet 12 is mounted the permeable layer 35 of acidic material, which coincides, when sheets 12 and 14 are superimposed, with a corresponding similar layer 37 at the trailing edge of sheet 24. Thus excess processing liquid is trapped, retained, and neutralized by the acid layers. A number of suitable acid compounds are given, citric, tartaric, and sulphamic acids being particularly preferred examples. The acidic material is contained in a permeable polymeric or absorbent paper layer, and again a number of suitable examples are given. The camera (Fig. 6, not shown) in which the film unit is used is similar to that described and shown in Specification 1,000,332. When loaded into the camera, the film unit is folded and arranged as shown in Fig. 5. The photosensitive surface of sheet 12 faces outward, and the printreceiving face of sheet 14 faces inward in the same direction. A pressure plate 58 is provided intermediate sheet 12 and the remainder of the unit, for supporting sheet 12 in the exposure position, and having a rolled end section 60. A number of such units are housed in a container (Fig. 4, not shown). After loading into the camera, a film unit, after exposure, is withdrawn by means of a narrow leader 70, which is attached to tapered leader 20, and whose end is folded over as at 80. The arrangement is similar to that described in Specification 1,000,332. Sheet 12 is pulled round the rolled end 60, and brought into superposition with sheet 14, the two being pulled together between pressure rollers in the usual way to rupture the container of processing material which is then spread between the sheets. Excess processing solution is absorbed and neutralised as described above.

Abstract: 501,740. Electron multipliers and circuits therefor. VEREINIGTE GLUHLAMPEN UND ELEKTRIZITATS AKT.- GES. Aug. 30, 1937, No. 23673. Convention date, Aug. 28,1936. Drawings to Specification. [Classes 39 (i) and 40 (v)] The electron beam leaving a cathode of an electron multiplier is passed through one or more screens with rectangular or slot-like openings so'as to restrict the beam to electrons having approximately the same velocity and direction and is then subjected to velocity and deflection control so as to cause the beam to fall either on a multiplying or a non-multiplying electrode as required ; if the path of the beam is guided in known manner by a magnetic field and accelerating electrodes the initial velocity of the beam should,be at right angles to the magnetic field and parallel to the field of the accelerating electrodes. Deflection plates for controlling the beam should be parallel to both the electric and magnetic fields. Velocity control may be produced by a grid. The non- emissive electrode may be coated with carbon and may form part of the same plate as the emissive electrode; any secondary emission from the non-emissive electrode may also be suppressed by a grid. The beam can be controlled at different stages; e.g. a weak signal may act on the discharge behind the primary cathode and a stronger local signal behind a multiplying electrode; the local signal may also be back-coupled on to the control member by means of an auxiliary anode near the working anode.
