Title: Improvements in means for protecting inflammable liquids stored in bulk from fire
IPC: A62C3/06
Filed: 1921-12-13
Abstract: 194,411. Sevian, V. Dec. 13, 1921. Fires, minimizing in receptacles for inflammable liquids.-A tank A for storing inflammable liquid has a pipe 17 communicating with a subsidiary reservoir to which, in the event of fire, the liquid can flow owing to the opening of a rotary valve 15 by the fall of a weight 16 acting on a drum 14 by a toothed band 13, this band being connected by a wire 2 to parallel wires 1 which are fused by the fire Cone 3 floating on the liquid directs the flames on to the fusible metal wires. Tube 12 protects the wire 2 and by its own expansion compensates for expansion of the metal wires due to ordinary temperature changes. These small changes are also allowed for by valve 15 not opening until turned to a considerable extent. To prevent the flames from following the liquid down the pipe 17, valve 19 drops on a seating on the end of pipe 17 when a fusible metal wire 20, Fig. 2, is fused by the flames. Members 26 are guides and member 80 is a weight to assist the downward movement of the valve. Rim 26 also prevents the burning liquid from flowing down the pipe 17. In a modified form of device for preventing the flames from following the liquid the valve 19 is supported by a tube 41 and fusible ball 44; before this ball fuses and allows the valve to drop, fusible ball 42 melts and allows a bell 46 to drop and close the pipe 17 before the valve 19 does so. The compression of a spring 43 by a plate 45 assists in the downward movement of valve 19 when the ball 44 fuses. Fusible rings 35, Fig. 2, and 47, Fig. 7, serve to seal the joints when the parts have fallen.

Title: Improvements in and relating to target structures for electron discharge devices
IPC: H01J35/08
Filed: 1946-11-13
Abstract: 643,011. Casting composite articles. BRITISH THOMSON-HOUSTON CO., Ltd. Nov. 13, 1946, No. 33731. Convention date, Nov. 13, 1945. [Class 83 (i)] [Also in Group XL (a)] A method of mounting a metal target for an electron discharge device on a support base of metal readily soluble with the metal of the target, consists in casting the base with a pocket in it, the pocket being formed by an insert which is a lining of metal difficultly soluble with the metal of the target, and then casting the metal of the target from the molten state in the pocket, where it remains as a solid target button. The anode 12 of an X-ray tube shown in the drawing comprises a base 26 of copper, iron or nickel having a targetcarrying end 27 formed with a cavity 28 lined with a cup-shaped insert 29 of tantalum, tungsten or molybdenum carrying a germanium target button 30. The lining 29 may be applied by casting it in the portion 27 during the formation of the base 26, e.g. the base can be formed by a casting operation in a die in which the pre-formed lining cup 29 may be mounted as an insert and the material of the base cast into the die upon and around the cup 29. The material of the base 26 is sufficiently soluble with the material of the cup 29 to wet it and secure it firmly in the end of the portion 27. The anode material germanium, in molten condition, can be poured into the cup 29 and allowed to solidify to form a target button 30. The materials of the cup 29, tantalum, tungsten and molybdenum are difficultly soluble in molten germanium which, however, will wet the material of the cup 29 sufficiently to form an anchorage for the target button 30. After solidification of the button 30 the surface 19 may be ground or polished.
