Title: Photographic camera
IPC: G03B7/00
Filed: 1959-08-14
Abstract: 925,517. Photo-electric exposure control. AGFA A.G. Aug. 14, 1959 [Aug. 26, 1958], No. 27932/59. Class 40 (3). [Also in Group XX] In a camera having a device for the control of the diaphragm setting means and of the shutter speed setting means, according to a predetermined schedule, said device comprises a cam for controlling each of said setting means, the two cams being movable together by a common operating member, and means for limiting the path of movement of said common operating member in accordance with the exposure value desired or indicated by an exposure meter. As shown (Fig. 1) diaphragm setting ring 5 and shutter speed setting ring 6 respectively carry arms 14, 15 which are engageable by cams 12, 13 on a slidably mounted common operating sleeve 8 for causing setting rotation of said rings against loading of springs 16, 17. In operation, said sleeve is depressed against loading of a spring 25 by means of manual operating member 22 (Fig. 2) until an exploratory member, which may be integral with or coupled to the member 10, comes into engagement with a pointer of an exposure meter, whereby further movement of sleeve 8 is prevented. The values of diaphragm aperture and shutter speed then set according to said predetermined schedule correspond to the prevailing light conditions. It may be arranged that further movement of member 22-after sleeve 8 has been locked-releases the shutter (not shown). In modifications, member 10 may be coupled to a follow-up pointer of an exposure meter and the cams may be arranged to be rotatable about the objective axis (as described in Specification 925,516).

Title: Improvements relating to the manufacture of transparent luminescent screens
Inventor: TURNER GEORGE CHRISTIE
IPC: H01J9/22
Filed: 1959-08-18
Abstract: Method of manufacturing a transparent luminescent screen comprises forming a transparent layer of at least the base material of a phosphor on a transparent supporting plate, immersing the plate and layer in water in a pressure-tight vessel together with a quantity of the phosphor sufficient to ensure a continuously saturated solution of the phosphor when the vessel is heated, and heating the vessel at such a temperature and for such a time that the temperature and pressure produced within the vessel are sufficient to maintain the constituents of the phosphor in solution and to cause diffusion of the activator ions into the appropriate lattice sites in the transparent layer.  The water can contain phosphor base modifying constituents and/or one or more activator materials, or these may be deposited on the supporting plate during the initial coating step. In one example a plate of silica is vacuum coated with a transparent layer of magnesium potassium fluoride and, after cooling, is placed in a silica ampoule filled to about half its volume with an aqueous solution containing 0.1% of manganese fluoride, 0.3% of zinc fluoride and a 5% weight by volume suspension of magnesium potassium zinc fluoride activated with manganese.  The silica ampoule is then sealed and placed in an autoclave filled to about half its volume with water and heated to a temperature of 400 DEG  C., corresponding to an internal pressure of about 300 atmospheres, for 20 hours.

Filed: 1946-09-20
Abstract: 616,913. Actuating beer engines; pneumatic single-stroke apparatus. BEACH, E. F. Sept. 20, 1946, No. 28231. [Classes 8 (ii) and 102 (i)] An apparatus for operating a beer engine consists of a main jack 18 having a piston 24 forming the upper end of an auxiliary jack 19, fixed to the beer engine casing 13, and containing a piston 23 which is secured to a movable pistonrod 20 attached to a piston-rod 26 of a pump 10 adapted to deliver beer through a pipe 14 to a delivery spout. A port 27 and a pipe 28 connect a pneumatic service line with a chamber 180 in the jack 18 through a control valve 29 actuated by a hand-lever. A chamber 190 within the jack 19 is connected by a pipe 33, with the lower end of a vessel 34 containing oil, by way of an adjustable needle valve 35. To operate the pump 10 air is supplied to the chamber 180 to cause the jack 18 and rod 20 to rise relative to the jack 19 and the piston 24, at the same time raising the piston-rod 26 to discharge beer to the delivery spout. Concurrently the piston 23 forces oil from the chamber 190 to the vessel 34 to increase the pressure of the air in the vessel 34 which has previously been admitted through a ball valve 38, thereby forming a cushioning buffer for the last portion of the power stroke. On release of the hand lever the valve 29 connects the chamber 180 to exhaust through the pipe 28 to allow the pressure in the vessel 34 to force the oil back into the chamber 190 to restore the piston 23 to its initial position ready for the next power stroke. Specifications 425,207, [Group XXIX], and 485,617 are referred to.

Abstract: 427,113. Cathode ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Vance, A. W.; 109, North 5th Street, Camden, New Jersey, U.S.A.) Oct. 16, 1933, No. 28618. Convention date, Oct. 15, 1932. [Class 39 (i)] The deflecting means of a cathode-ray tube in television, oscillograph &c. systems are so arranged that, when the two sets of electric oscillations applied for deflecting the ray in directions at right angles are each of constant amplitude, the ray scans a keystone-shaped area in a plane perpendicular to an axis 24 defining the mean direction of the ray and so a rectangular area on a screen 12 inclined to this axis, distortion of the picture due to the inclination of the screen being thus avoided. In a television transmitter in which a photoelectric mosaic screen 12 inclined to the axis of the electron gun 20 has an optical image projected normally to the screen from a film 14, the ray is deflected horizontally by coils 28, 32 of unequal numbers of turns so that their vertical magnetic field is stronger below the axis 24 and a rectangular picture is obtained. The ray is deflected vertically by coils 26, 30 having a centre line below the axis 24 so that a rectilinear wave-form of current in the coils 26, 30 produces a uniform displacement of the ray up the inclined screen and an even spacing of the horizontal lines of the picture. The four coils are arranged on a core surrounding the tube as shown.
