Title: Shock Resistant Multiple Switch Assembly
IPC: H01H3/60
Filed: 1968-07-30
Abstract: 1,192,842. Switches retained set. CLAREPENDAR CO. 30 July, 1968 [11 Aug., 1967], No. 36267/68. Heading H1N. In a multiple push-button switch assembly of the kind in which one of the push-buttons is held set by a slide assembly (Fig. 5) and can be released by depressing another push-button, an inertia device 25 is provided, responsive to acceleration of the switch assembly, to lock the slide assembly and thus prevent release of the push-button by the acceleration forces. The device 25 comprises a piston (27) and spring (32) (Fig. 3, not shown), movable in the same direction as the push-buttons 14 and having a spring force to movable mass ratio substantially less than that of any of the push-button switches. Each push-button 14 has an extension 20 which co-operates with an opening 40 in a fixed member 38, to prevent rotation, and with slides 42, 60 which are provided respectively with opposed latch portions 48, 67. Depression of a button causes an extension 20 to drive the portions 48, 67 apart against springs 80 by engagement with cam surfaces 50, 71. The extensions 20 also co-operate with a series of members 75 to prevent depression of more than one button at a time. The piston (27) is also provided with an extension 30 which is driven by acceleration forces parallel to the pushbuttons into recesses 58, 72 in the slides 42, 60. Since two opposed slides are provided acceleration forces parallel to the slides are also unable to release the switch. Cut-away portions adjacent the recesses 58, 72 allow the piston (27) to move a shorter distance to lock the slides than the push-buttons move to release them.

Title: Process for the generation of a fuel gas of high calorific value
IPC: C01B3/36
Filed: 1957-12-03
Abstract: 836,940. Fuel gas. TEXACO DEVELOPMENT CORPORATION. Dec. 3, 1957 [Dec. 7, 1956], No. 37622/57. Classes 55 (1) and 55 (2). In a process of making a fuel gas of high calorific value, a heavy oil is introduced into a stream, preferably superheated, and the mixture is subjected to high turbulence to disperse the oil in the steam while maintaining some oil in the liquid state, and a hydrogen- and carboncontaining fuel is partially combusted to produce a gas containing hydrogen and carbon monoxide at a temperature of 1800‹ to 3500‹ F., the oilsteam dispersion being mixed with the gas containing hydrogen and carbon monoxide and the resulting mixture passed at a temperature of 1000-1600‹ F. over a cracking catalyst. The fuel partially combusted to produce the gas containing hydrogen and carbon monoxide may be coal or a portion of the oil-steam dispersion. The partial combustion and the contact with the cracking catalyst may be effected at a pressure of 100 to 1500 lbs. per square inch. The cracking catalyst may be disposed as a fixed bed or as a fluidized bed of particulate solids and may contain nickel and/or chromium, or iron group metals or bauxite. In the apparatus shown, steam produced in a coil 11 and heavy oil from line 16 are introduced into a coil 18 heated to a temperature between 300 and 1000‹ F., the amount of steam being between 20 and 300% by weight of the weight of the heavy oil. The mixture of oil and steam in the coil 18 has a velocity greater than 20 feet per second and the dispersion leaving the coil contains at least 70% of the oil in vapour form. A portion of the oil-steam dispersion is fed by line 24 to a zone 28 where it is partially combusted with oxygen introduced through line 27. The remainder of the oil-steam dispersion is mixed with the gases produced in the zone 28 and passed into a catalyst zone 33, product gas leaving by line 41. The process is periodically discontinued to allow carbonaceous deposits in the catalyst zone to be removed by combustion. If, however, a fluidized bed of catalyst is employed, the catalyst may be continuously withdrawn for regeneration. When coal is used to produce the gas containing hydrogen and carbon monoxide, a dispersion of particulate coal and steam is formed by heating a coal-water slurry in a heating coil and partially combusting this dispersion in a vertical generator with oxygen at a temperature between 2200‹ and 3500‹ F., slag and gases containing hydrogen and carbon monoxide being separately withdrawn in a lower zone of the generator.
