Title: Improvements in or relating to louvres for the control of air or other gas
IPC: F24F13/15
Filed: 1955-11-25
Abstract: 772,947. Ventilators. CRITTAL & CO., Ltd., R., and COX, W. R. Nov. 25, 1955, No. 33816/55. Class 137 In a louvre construction, particularly for directing the flow of air from ducts, each blade_4, constructed from a single strip of metal, Fig. 3, is supported at each end in a frame 1 by one leg 2 of a U-shaped member which is made of wire, or rod, and projects through the respective side of the frame. The remaining leg of each U- shaped member serves, in a similar manner, to support an adjacent blade. Each leg 2, which projects into an opening in the corresponding end of the associated blade, may be made a tight fit so that the louvre blade may be retained in any adjusted position. When the blades are to be moved simultaneously by a comman operating member, not shown, they are made to fit loosely around the legs 2 which may be tapered at their ends to facilitate assembling. Coninuous recesses may be provided in the sides of the frame to accommodate the base portions 3 of the U- shaped members. In a modification each U-shaped member is constructed of two pins which constitute the legs, the base of the U-shaped member consisting of a plate to which the pins are riveted. If there is an odd number of louvre blades one leg of each of one end pair of U-shaped members is removed and the bases 3 of those members are secured, e.g., by welding, to the frame 1. The plate forming the base of any U-shaped member may be extended for the mounting of one, or more, additional pins.

Abstract: 1,048,559. Electron beam recording. TECHNICAL OPERATIONS Inc. Sept. 3, 1963 [Sept. 4, 1962], No. 34847/63. Heading G5R. A method of recording by directing a modulated electron beam against a record strip 10 uses a record material as a target comprising micro-crystals of silver halide, principally the bromide, supported on a substrate, preferably of baryta paper, but which may be polyterephthalate film or glass, primarily by binding the crystals directly to the substrate and to one another without an emulsion vehicle. Comparison with a conventional photographic lantern plate shows that the non- emulsion record layer is markedly more sensitive to electron irradiation. Record tracks may be made by exposure:- (a) frame by frame with a 2-dimensional raster deflection; (b) transverse track by linear scan of the beam as the strip 10 moves; or (c) longitudinal track by a stationary beam as the strip 10 moves. Exposure in each case may be, according to mean beam intensity:- (1) normal latent negative image, developed at 13; (2) latent image developable as a positive by suitable modification of process at 13; or (3) bombardment sufficient to produce a directly visible image not requiring development. The record structure, the development processes and the arrangement of the recording tube 12 are separately known per se. The claims are limited to the method using the combination thereof.
