Title: Improvements in apparatus for use in connection with the supply of liquids, particularly to tanks mounted on motor vehicles
IPC: B60K15/00
Filed: 1925-11-20
Abstract: 266,430. Thompson, F. S., Thompson, H. J., and Leverick, F. Nov. 20, 1925. Tank wagons.-Relates to a system of valves and passages for controlling the flow of liquids, particularly in connection with tank wagons, and comprises a plug valve capable of reversing the direction of flow of the liquid through the system notwithstanding that the liquid flows always in the same direction through the supply or force pump and also capable of throwing the pump out of circuit when it is desired to use gravity for promoting the flow. The reversing valve comprises a plug b and shell c, and the plug is provided with two T-shaped passages 1, 2, 3 and 5, 6, 7 respectively, at right angles to one another and situated one above the other, and the shell is provided with ports corresponding with these T-shaped passages and with the conduits connecting to the supply A, the output and input sides 12, 13 of the pump C, and the delivery conduit 11 to the tanks. As shown, liquid from the supply A passes to the input of the pump through the lower T-shaped passage and from the output of the pump to the delivery conduit 11 through the higher T-shaped passage. The plug valve may be turned to reverse the flow by putting the conduit 11 in communication with the input side 13 of the pump and a conduit 14 in communication with the output side 12 of the pump. A passage M in the plug valve with ports 9, 10 at different levels enables the pump to be shortcircuited, or may be used to shut off the pump and put the conduits 11, 14 in communication when gravity is utilized to produce the flow. A distributing valve E is adapted to distribute the liquid to or from conduits J, H, G, F leading to different compartments of a tank, or to or from an external conduit K. The pump C is provided with a safety bye-pass D.

Abstract: 1475930 Power steering TRW Inc 3 July 1974 [27 July 1973] 29496/74 Heading B7H In a power steering arrangement of the type having a piston 36 disposed within a cylinder 28 defining separate hydraulic chambers 38, 40, the piston being coupled to a steering wheel shaft 44 by means for translating rotary motion of the shaft 44 to an axial movement of the piston 36 and carrying rack teeth for engaging with a sector gear 70 carried on a cross shaft 72, the steering wheel shaft 44 operating a valve 48 for selectively pressurizing the hydraulic chambers 38, 40, a pressure relief mechanism 96 is carried by the piston 36 and operable to relieve pressure above a predetermined level in the respective chambers 38, 40. The pressure relief mechanism includes a normally closed fluid circuit in the piston 36 extending between the chambers 38, 40 and includes two bores 100, 114 extending at right angles to each other each bore having a fixed valve seat member 106, 122 and a quick opening spring biased valve member 98, 116 normally urged into engagement with the respective seat member. A pressure build-up to relief pressure within chamber 40 is effective via bores 108, 110, 112 and 114 against surface 134 of valve member 116 to unseat the valve member 116 and communicate the chamber 40 with the arcuate groove 130 and the chamber 38. Pressure build up in chamber 38 is transferred to chamber 40 in a similar manner. The valve 48 is of the open-centre type wherein rotation of the steering shaft 44 in the intended direction of turn causes rotation of the valve member 47 relative to valve member 49, Fig. 3, to cause the appropriate one of the pressure chambers 38, 40 to communicate with the high pressure fluid in the flow passage 80 and the other pressure chamber to communicate with the flow passage 88. A torsion bar 90 connected between valve element 47 and the steering shaft 44 which is fixed to valve element 49 ensures that the valve elements 47, 49 become aligned in the neutral position when the steering shaft 44 is not being rotated.

Abstract: 652,341. Photographic reliefs. DEBENHAM, F. Nov. 15, 1948, No. 29589. [Class 98 (ii)] [Also in Group XV] Relief maps are made by forming, as by cutting out, layers of tinted transparent material corresponding in shape to the different contour lines of a contoured map, superimposing such layers on the contoured map so as to form a base map in which each contour level has a light density proportional to its height above sea level, forming a graduated density negative photographically from such base map and forming a photographic reproduction in relief of the graduated density negative. The step effect between the various contour levels of the base map may be reduced by shaving or trimming the edges of the layers, or by photographing the base map slightly out of focus. The graduated density negative may be formed in enlarged or reduced scale. The final reproduction may be in negative relief and a positive cast in wax or plaster made therefrom.

Abstract: 1317462 Pyrotechnic devices DYNAMIT NOBEL A G 18 June 1970 [19 June 1969] 29732/70 Heading F3A [Also in Division H1] A switch for use in a rocket comprises a pyrotechnic composition 7, Fig. 1, which, on combustion permits displacement of a member, 14, the heat for igniting the composition 7 being channelled through a bore 2, 4, 5. The heat is that generated by the rocket. The member 14 is normally held against displacement by a steel plate 8 which bears against the composition 7. However, upon igniting the composition, the member 14 is displaced as the plate 8 is pushed by a spring 10 into the molten slag. Alternatively, the member 14 is held against displacement by a fusible element (not shown) which is trapped between sleeves 6 and 15, and is melted by the heat of combustion of the composition 7. The composition may burn with delay. In another embodiment, Fig. 2, a propellant 22 is ignited by a heatsensitive primer 24, and the propellant gases serve to displace a piston 25, 26. A split-ring (not shown) engages one side of the piston head before displacement and the other side after displacement to secure the piston.
