Filed: 1945-03-26
Abstract: 593,089. Interrupters. WILLIAMS, A., and MEYER, O. E. March 26, 1945, No. 7591. [Class 38(v)] In a rotary interrupter for electric ignition devices, recoil mechanism associated with a cam-operated movable contact comprises two aligned springs within a uniformly dimensioned chamber coacting with each other and with the movable contact to produce instantaneous make and break. A distributor casing 1 is insulated from the operating shaft 9 by a bush 13. As the shaft 9 rotates it drives a cam 11 with one or more arms 12 which, as the shaft rotates, cause a series of moving contacts 34 in turn to reciprocate and engage fixed contacts 32. Each contact 34 is slidably mounted in a cartridge B, shown in detail in Fig. 3, and is biased towards the shaft 9 by a spring 42 acting on a disc 40 secured to the contact 34. When a rod 36, tipped with fibre 38, is actuated by the arm 12, a disc 39 on the rod compresses a weak spring 41 as the rod 36 telescopes within contact 34, which moves to make yielding contact as the spring 41 is compressed and overcomes the spring 42. The contacts 32, 34 may be tipped with silver, tungsten or platinum. The cartridges B are gripped between metal rings 20, from which they are insulated, the rings 20 being insulatedly mounted on the casing 1. The contacts 32 are insulatedly and adjustably mounted on the casing 1. The cam 11 may have a plurality of lobes co-operating with one or more cartridges.

Filed: 1958-03-07
Abstract: 824,982. Vehicle power steering. BENDIX AVIATION CORPORATION. March 7, 1957, No. 7618/57. Class 79(5) [Also in Group XXIX] A valve for controlling power steering of a motor vehicle consists of inlet and outlet ports 16a, 18a, working ports 20a, 22a and a movable valve member 24a coacting with two valve members 46a which isolate the inlet port from the bore in which the valve member 24a operates when the latter is in its central position to which it is urged by a loading spring 118a. When the valve member 24a is displaced from its central position, in which it allows communication between the two working ports and the cutlet port, it lifts one of the valve members 46a by means of a conical surface 210 or 212 to connect one of the working ports with the inlet port. At the same time a land 56a interrupts communication between that working port and the outlet port and allows unrestricted communication between the other working port and the outlet port. Reaction chambers 62a, 64a at each end of the valve member 24a receive fluid under pressure from each working port through passages 66a, 68a to provide "feel". Unequal reaction areas may be used as in Specification 779,122 and reaction limiting may also be employed by using regulating valves as in Specification 812,827. The valve members 46a are spring loaded and hydraulically balanced by the provision of passages 47a. The valve members 46a instead of being provided with stems as shown may be loose ball valves. Also, instead of being actuated by conical surfaces 210, 212 they may be lifted from their seats by discs having depending stem which engage with annular grooves in the valve member 24a whereby one or other of the discs is tilted when the valve member 24a is moved from the central position. A further arrangement is described in which only a single inlet valve member 46a actuated by a tilting disc is provided.

Patent GB-165418-A (GB)
Title: Improvements in fuel
IPC: C10L1/32
Filed: 1919-12-22
Abstract: In a liquid or paste fuel which is heavier than water, which is mobile and atomizable or is rendered so by moderate heat, and which consists of a suspension in 90-25 per cent of liquid hydrocarbon or fuel oil of 10-75 per cent of solid carbonaceous particles, the suspension is stabilized by the addition of a protective agent, such as a lime, soda, or potash resinous or other soap or a saponaceous body obtained by treating oil or coal with alkali or the like.  The protective agent may be used in liquid, paste, powder or other solid form or as grease by addition of oil.  The preferred form is made, for example, by saponifying 10 parts resin by 5 parts lime slaked and suspended in 83.5 parts Texas navy oil and 1 1/2 parts water.  The resin may be replaced by balsams, turpentines and other resinous by-products.  Usually such an amount of this protective agent is used as will add 0.5-1.5 per cent resin to the fuel.  The carbonaceous substance is reduced until about and preferably more than 95 per cent passes through a screen of 100 mesh to the linear inch and 85 per cent through a screen of 200 mesh, and is then mixed with the liquid hydrocarbon by passage through a ball, tube, or paint mill, or by heating; or the solid may be reduced in presence of the liquid. Suitable carbonaceous substances specified are anthracite, semi-anthracite, bituminous and semi-bituminous coals, lignites, peats, pressure still, smelting, and gas cokes and charcoals, and wood.  Suitable liquids mentioned are fuel oils, pressure-still oil or tar, coal tar from coke ovens or gas works, and molasses.  The liquid should preferably have a viscosity of about 20 DEG  Engler at 20 DEG  C. and 10 DEG  at 30 DEG  C.  In an example, 30.5 parts Pocahontas coal ground so that 85 per cent passes a screen of 300 mesh per inch, 68.0 parts Texas navy oil, and 1.5 parts of the lime-resin grease are blended in an ordinary paint-mixing machine with a 200 lb. wheel running at 70 revs. per minute.  Other stabilizing measures may be used in addition as described in Specification 149,306.  Specification 17729/13 is also referred to. According to the Specification as open to inspection under Sect. 91 (3) (a) the viscosity of the liquid may be increased or decreased. This subject-matter does not appear in the Specification as accepted.
