Title: Method for producing highly emitting oxide cathodes for electron tubes
IPC: H01J9/04
Filed: 1926-11-18
Abstract: 275,542. Schrack, E., and Ettenreich, R., (trading as Radiowerk E. Schrack). Aug. 6, 1926, [Convention date]. Vacuum tubes.-Material for forming an oxide coating for a cathode is applied to a carrier in the form of a spray, and preferably after the carrier has been secured in its supports. The material, such as carbonate or other salt of an alkaline earth metal, preferably strontium, or of radium or lanthanum, is held in suspension or solution in a readily-vaporizable, liquid such as alcohol, benzene, or ether, with an adhesive; for instance a solution of resin or hydrocarbon in alcohol may be used, or a solution of gum arabic in water. The carrier wire may consist of tungsten molybdenum, or thoriated tungsten, and in order to ensure subsequent adhesion of the oxide, the wire is coated electrolytically with gold, platinum, nickel, copper, silver or iron, but preferably with carbon, as by heating the wire in a mixture of hydrogen and acetylene, or hydrogen saturated with tetrahydronaphthalene. The wire is welded to supports mounted in the bulb and the coating is sprayed on, the solvent and adhesive being subsequently evaporated by heat. During this process the supports for the other electrodes are shielded by screens, the grid being compressed and shifted over its supports. The carbonate is converted into oxide by heat before or after the final evacuation, and residual gas is removed by a calcium or magnesium mirror or other absorbent. Specifications 229,655, 233,375, 245,146 and 245,147 are referred to.

Abstract: 533,469. Kinematograph apparatus. KODAK, Ltd. Nov. 8, 1939, No. 29640. Convention date, Nov. 8, 1938. [Class 97 (i)] A stationary guide member extending between a feed sprocket and the gate to facilitate threading is provided with a movable loopforming means which, when in loop-forming position, increases the extent of the periphery of the sprocket engaged by the film. As shown, two stationary guides 21, 21<SP>1</SP> extend between a sprocket 17 and a gate 14, 15, and loops are formed by rollers 41 movable through slots in the guides from the threading position, Fig. 3, to the loop-forming position, Fig. 1. The rollers are carried by brackets 30 on pivots 31, and each bracket carries a shoe 32 with a curved end 35 which guides the film F against the guide during threading, and ensures that it contacts wholly with the curved parts thereof near the gate. The brackets have teeth 48 engaged by intermeshed gears 49, 50, and are turned by a control lever 51 having teeth meshing with the gear 49. The gate member 15 is pivoted at its lower end, and is connected by links 56, 58, and a bell-crank lever 57, to the lower bracket, so as to open and close with movement thereof. The film is guided to the take-up spool 18 by a channel 62 having an expanded mouth and engaging a slot 67 in the spool hub. Lugs 68, 70 respectively enter the slot and limit the amount of entry so as to hold the spool and permit entry of the film end into the hub. The channel is pivoted at 63, is held by a spring 69, and has a curved part 71 engaged by the film, so that the film, by its resilience, may turn the channel after the film end engages and presses against the inner surface of the hub. The spool is then freed, and the lugs 68, 70 ride on the film margins as the spool rotates. Specification 255,091, [Class 97 (i)], is referred to.

To ensure that inaccuracies due to distortion may be detected in an enlarged print of a film recording the finish of a race; which film has been produced by the known method of disposing a camera having a slit aperture on a line extending across a race-course perpendicular to the length of said course and passing through the winning-post, and moving the film in said camera in synchronism with the images of the contestants in the plane of the film, and wherein the camera is provided with means for recording a datum line on the film along its length, such a film is placed with a screen having a rectangular grid pattern in the negative holder of an enlarger with the film datum line parallel to one of the grid lines and a composite projection print is made of said film and grid. As shown, the film bears along one margin parallel marks 17 produced by a flashing lamp and images 18 of race indicia carried on a rotating drum which together with the lamp is housed in the winning- post. A datum line 29 extending longitudinally of the film is recorded by disposing a wire perpendicularly across the camera slit, said wire being carried on threaded sleeves adjustable by screws. A glass sheet marked with a grid of rectangles and forming the negative support of an enlarger is illuminated to project an image thereof on to the printing table and the objective which is provided with three adjusting screws is adjusted until the grid is in focus and the rectangles undistorted. The race finish film negative is then placed in the negative holder, the datum line 29 is registered with one of the grid lines 39, and the negative is then clamped by a heavy glass plate. The printing table and print-holding frame are then moved as a whole until a line 46 on the glass cover of the frame is parallel to one of the projected grid lines 40. Thereafter, the frame is slid along parallel guide-ways on the table until the line 46 coincides with a desired point of the projected image. A sheet of printing paper is placed in the frame which is then closed and an enlarged print made. Specifications 537,253, 640,936, 624,095 and 630,956 are referred to.
