Title: Improvements in microphonic capsules for use in telephone transmitters
IPC: H04R21/02
Filed: 1924-03-21
Abstract: 229,879. Western Electric Co., Ltd., (Rutten, L. van). March 21, 1924. Microphones. - The casing of a microphone capsule is formed of two cup-shaped portions 1, 2 of non-inflammable celluloid or other non- inflammable material, telescoping one inside the other and stuck or glued together as by a solution of non-inflammable celluloid in acetone. Between the two portions is a barrier 5 of insulating material provided with a number of holes 6. The electrodes 7, 14 are mounted on supports 8, 15 and washers 12, 17 of oiled cloth or similar material between these supports and the walls of the casing prevent the entrance of moisture. If the two portions 1, 2 of the casing be made of the same shape, the barrier 5 is held midway between the electrodes by means of spring rings.

Title: Improvements in temperature responsive regulating arrangements
IPC: F01D17/08
Filed: 1966-02-18
Abstract: 1,121,804. Valves. DAIMLER-BENZ A.G. 18 Feb., 1966 [24 Feb., 1965], No. 7283/66. Heading F2V. [Also in Divisions F1, G1 and G3] A thermally actuated drain valve connected to a pressure chamber 10, Fig. 1 (not shown), in which is mounted a pressure-responsive diaphragm regulator for an aircraft engine, serves to regulate the fuel feed to the engine and comprises a heatsensitive tubular element 13, Fig. 2, a displaceable rod insert 14, and a toggle lever system 20, 22 which magnifies the relative movement between the thermal elements and actuates a pneumatic regulator housed in lateral socket 26 of tubular pillar 5. The tubular element 13 which may be made of steel is closed at its upper end 16 and is provided at the other with a guide bush 15. The displaceable insert 14 which may be made of quartz is fitted with a steel intermediate 17 and a piston 18 slidable in a bush 15. Lever 20 is pivotally connected at 19 and 21 to the piston 18 and a second lever 22. The lower end of 22 is supported in a V bearing 24, in a pillar 5, which at its upper socketed end 5a contains bush 15 secured by collar 25. A guide bush 27 is secured in socket 26 by a spring 28, and an annular chamber 29 is provided between the bush and socket. A slidable sleeve 30 is mounted in guide bush 27 and pushed to the right by spring 31, until its end 32 meets a projection 33 on lever 22. A tension spring 35, pivotally connected between the upper lever and an extension on the pillar 5, serves to press the upper end of bar 14 and end 23 of lever 24 tightly against their respective sockets. When the temperature of the elements is raised, the tube 13 expands more than the rod 14, and piston 18 and lever 12 move upwards whilst joint 21 and lever 22 move to the left under the action of spring 35. Projection 33 on lever 22 displaces sleeve 30 to the left against the action of spring 31, whereupon circumferential bores 37 and 38 in the bush and sleeve respectively are brought into coincidence and compressed air fed to annular chamber 29 by a pipe (6) escapes in the direction of arrows 39, Fig. 3 (not shown). This reduces the pressure in the chamber (10) and throttles the fuel supply to the engine. Adjustment to the required temperature is made by aid of bearing 24 which is surrounded by a threaded sleeve. Sensitivity is influenced by turning guide bush 27 in or out.
