Title: Improvements in or relating to charge storage tubes having double sided targets
Inventor: GIBBONS DAVID JOHN
IPC: H01J31/28
Filed: 1963-03-06
Abstract: 1,074,811. Charge storage tubes. ELECTRIC & MUSICAL INDUSTRIES Ltd. March 6, 1964 [March 6, 1963], No. 8861/63. Heading H1D. A charge storage tube, e.g. a television pickup tube, has a double sided target consisting of an electrically insulating layer having on each side a thin conducting coating and exhibiting volume charge storage which is the storage of electrons trapped in the insulating layer on their way from one layer to the other layer, the charges being stored by directed high velocity electrons, e.g. accelerated through 25 kv, on to one side of the target, the layers being held at different potentials thereby allowing electrons to penetrate into the insulating layer, and the charges being removed by directing high velocity electrons on to the other side of the target whilst maintaining the coatings at the same potential. The electrically insulating layer is zinc sulphide and at least one of the thin conductive coatings is of aluminium. The layer is manufactured by evaporating a thin film of aluminium on a collodion membrane mounted on a frame, removing the film by baking at 300-400‹ C. for an hour, followed by depositing zinc sulphide and a further layer of aluminium. Alternatively a thin aluminium oxide film may be used in place of the collodion film.

Abstract: 1451823 Motion picture cameras EASTMAN KODAK CO 28 Feb 1974 [28 Feb 1973] 9163/74 Heading G2E A motion picture camera has a door which can be closed to completely enclose the cartridge chamber within the camera in a light-tight manner, or can co-operate with a large cartridge which is only partly received in the cartridge chamber so that the part within the chamber is maintained in a lighttight condition. As shown, the door assembly 22 has an upper section 22b attached to a lower section 22a by hinge members 44a, 44b, 46a, 46b. The lower section is attached to the body 24 of the camera by hinges 26a, 26b. When the film cartridge is small enough to fit completely into the cartridge chamber, the door assembly can be completely closed, as in Fig. 1, the upper section 22b being spring-urged into a position perpendicular to that of lower section 22a. When a cartridge 32 of larger film capacity is used, only the lower part 32a fits into the chamber, the enlarged portion 32b extending out above the camera, as seen in Fig. 5. Thus the upper door section 22b is prevented from closing completely. Resilient pad members 36, 38 and 40 are provided such that the light-sensitive film in the lower part of the cartridge is shielded from ambient light. Pad 36 is L-shaped, and supported by a correspondingly shaped rib 42 fixed to door section 22a. When this section is closed the pad engages with a rib 34 on the cartridge and with the walls of the cartridge itself. A latching mechanism (seen in detail in Fig. 10 not shown), has two bars (76, 78) which slide in opposite directions to latch the door section shut in either the Fig. 1 or the Fig. 5 position, and can be operated by a knob (100) on the exterior of the camera.
