Title: Sound-film band and process of recording sound thereupon
IPC: A47L5/28
Filed: 1929-08-03
Abstract: 334,354. Selenophon Licht-und Tonbildges. Oct. 25, 1928, [Convention date]. Optical apparatus and records.-Relates to a sound-film 1 having dark and light zones 8, 9, side by side, separated by a zig-zag line 10, and which is formed by light being obscured by a conductor which receives currents from a microphone, and which vibrates in a constant magnetic field. According to the invention, in recording. an adjustable screen 3 is inserted into the path of the light rays, the screen regulating the intensity of illumination uniformly across the whole width of the sound record and being adapted to be more or less opened according to the intensity of the sound which is to be recorded. The light zone 9 of the film is thus variably transparent.. As shown, the screen consists of a tubular member 3 pivoted at 4. It may be operated by hand so that, when the sound to be recorded increases in strength, the screen is tilted to permit more light to pass through and vice-versa. Alternatively, the screen may be operated automatically through links 6, 7, by an intensity regulator 5 working in combination with an amplifier for the microphone currents. Sound is reproduced in known manner by the action, on a light-sensitive cell, of light passing through the film.

Filed: 1928-08-22
Abstract: 296,059. British Thomson-Houston Co., Ltd., (Assignees of Niedergesass, B. F.). Aug. 24, 1927, [Convention date]. Reflectors.-A method of making an astronomical mirror consists in projecting heated silica particles on to a foundation plate 8 of opaque silica which is heated to a temperature approximating to the fusion temperature of silica. The particles coalesce and form a layer S of clear vitreous silica which is incorporated with the plate 8, and the compound plate is subsequently ground to the required configuration and polished. The plate 8 rests on refractory supports within an oven 10 and is preheated to about 800‹ C. by means of burners 11. The flame 14 from an oxyhydrogen burner 13 is directed on to the upper surface of the plate 8, and powdered silica from a receptable 18 is introduced into the flame, preferably by entrainment in a stream of gas. The flame raises the temperature of the spot on which it plays to about 1750‹ C., and the silica particles in the flame are fused and stick to the plate. The burner is moved about until the layer S is built up to the required thickness.

Title: Improvements in or relating to variable ratio relay valves
Inventor: PAGE WILBUR MILLS
IPC: B60T15/04
Filed: 1967-05-25
Abstract: 1,169,252. Valves; fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. 8 May, 1968 [25 May., 1967], No. 24320/67. Headings F2F and F2V. In a variable ratio relay valve controlling the supply of air at 22 to the front brakes of a vehicle, a piston 23 responds to a control pressure in chamber 15, as determined by a dual brake valve 12 controlling an air supply to the rear brakes, and moves downwards against spring 35 with piston 28 to disconnect outlet 22 from exhaust port 27 and to unseat valve member 18 thereby connecting outlet 22 to inlet 21. Rising outlet pressure acts via passage 37 on the lower faces of pistons 28, 29, the latter being held in contact with the former by spring 33, and reseats member 18. When the outlet pressure rises above a certain level, piston 29 moves upwards against spring 33 to abut stop 38. The control pressure is now balanced by the constant force of spring 33 and the outlet pressure acting on piston 28 alone. The ratio of control to outlet pressures consequently falls with further increase in control pressure.

Filed: 1937-09-07
Abstract: 489,817. Fluid-pressure servomotorcontrol systems. SCINTILLA, Ltd. Sept. 7, 1937, No. 24402. Convention date, Sept. 9, 1936. [Class 135] [Also in Group XXVIII] Fuel-injection apparatus for internal-combustion engines comprises an injection pump 1 having a feed pump 2 arranged at one end and a speed governor 3 at the other end. The pump 2, comprising gears 5 and 6, delivers the fuel through a duct 7 to a fuel supply chamber 33 of the injection pump and through a further duct 54 to one side of a piston 43 of the governor 3 for actuating the control rack 38 of the injection pump to regulate the fuel delivery. The pressure in chamber 33 is maintained constant by a regulating valve 10 which passes the remaining portion of the feed pump delivery at a pressure which varies with the speed of the pump to a passage 13 which is in communication with a byepass chamber 35 of the injection pump and which has an adjustable throttle return 14 to the feed pump. This variable pressure acts through a duct 56 on a piston 41 of a control valve 48 which regulates the pressure on the side 45 of the piston 43 which has a restricted communicating passage 49 between its two sides. This piston 43 therefore follows the movement of the control piston 41 to effect adjustment of the fuel delivery of the injection pump to govern the speed. The pressure in the passage 13 also acts upon a piston 21 of an injection timing device through a duct 17 to vary automatically the time of injection according to changes of speed.
