Patent GB-875515-A (GB)
Title: Improvements in or relating to control valves, more particularly power steering control valves
IPC: F15B11/20
Filed: 1959-03-13
Abstract: 875,515. Hydraulic apparatus; fluid-pressure servomotor systems; valves. BENDIX CORPORATION. March 13, 1959 [June 27, 1958], No. 8835/59. Classes 69 (2) and 135. [Also in Group XXXI] A valve 78 controlling the passage of fluid to an hydraulic motor 50 consisting of a fixed piston and movable cylinder connected by rods 54, 48 to the steerable wheels of a vehicle, such as a tractor, has means for allowing the passage of fluid also to a valve 20 of the " open-centre " type controlling a jack 30 of a lift system on the tractor, the arrangement being such that communication between the pressure supply conduit 14 and the valve 20 is normally established by the valve 78 through a conduit 18 but is interrupted should actuation of the steering be required when the valve 20 is in its centre position, in which it discharges fluid under pressure from the conduit 18 to a conduit 24 returning to the reservoir 12. The valve 78 is actuated by end thrust on a worm 36 driven by the steering wheel 38 and having connection through a sector 42 with the rods 54, 48. Should the steering wheel be turned so as to move the valve 78, say, to the left, communication between a motor port 105 and a reservoir port 77 is first closed by a land 96 whilst a land 88 simultaneously increases the communication between the other motor port 99 and the reservoir port 70. Continued movement of the valve results in a land 94 moving past the end of an annular recess 74 whereby the motor port 105 is placed in communication, through a passage 106, with the pressure supply conduit 14. At this stage, should there be no loss of pressure through the conduit 18, the motor 50 commences to operate and through follow-up gear including the rod 54 and sector 42 prevents further displacement of the valve 78. If, owing to lack of pressure in the conduit 18, the motor 50 fails to operate, the continued movement of the valve 78 will result in the land 94 moving past the left-hand end of the recess 74, thereby isolating the conduit 18 from the passage 106. Passages 108, 110 transmit the fluid pressures in the two ends of the motor to chambers 112, 114 to provide " feel."

Abstract: 922,541. Generating combustion products under pressure. MASCHINENFABRIK AUGSBURG-NURNBERG A.G. March 14, 1960 [March 28, 1959], No. 8845/60. Class 51 (1). [Also in Group XI] Liquid fuel from an intermittently or continuously operating non-atomizing injector 3 is spread in the form of a film 40 over the wall of the combustion chamber 1 of a gas turbine, combustion air is caused to sweep the combustion chamber wall at high speed and the combustion chamber wall is maintained at a temperature at which the period of dwell of the fuel particles thereon before vaporization is a minimum. The fuel injector 3 has a discharge slit disposed close to the combustion chamber wall. Air from a compressor (not shown) enters the combustion chamber and is caused to rotate by manually or automatically adjustable vanes 8. Further air from the compressor passes along an annular channel 12 to cool the combustion chamber wall and is controlled by a valve 13 comprising a radially slotted ring 15 and a co-operating slotted ring 16 which is rotatable and is coupled through a rack 19 and gearing 18 to a motor 17 controlled by a thermostat 14 inside the combustion chamber. Alternatively the valve 13 may comprise pivoted blades having cranks with pins engaging slots in a rotatable control ring located around the outer wall 11 of the annular air channel. Further air is introduced into the combustion chamber through nozzles 20 on the ends of valve controlled pipes 21 which are inclined in the direction of rotation of the air in the combustion chamber; alternatively if an increase in turbulence is required some of the pipes 21 inject air against the direction of rotation. Combustion products or air may be made to circulate in either direction through the core of the combustion chamber by means of two ducts 22, 24 having gate valves 23, 25. Air may also be introduced through a duct 22a at the outlet of the combustion chamber. At starting an atomized jet of fuel from a second injector 6 is ignited by a spark gap 5 and vaporizes the film of fuel.

Class 83 (iv) [Also in Group XXXIV] A bearing comprises an annular sintered metal powder body having an interior chamber or hollow from which lubricant is supplied to the bearing surface through the pores in the body. The body is made by forming a core of copperzinc alloy having the shape of the required hollow, compacting a mass of powdered iron with the core therein and then heating the compact to sinter the iron particles and to melt the core which infiltrates into the porous iron mass to leave a hollow or recess which is subsequently filled with lubricant. Alternatively the core may be of lead or lead antimony alloy and the matrix of bronze. A bearing bush 64 with an annular oil chamber 63, Fig. 2, may be formed by compacting iron powder in the form of a hollow cylinder around an annular core having the shape of the chamber 63. The core may be a helix 120 which is surrounded by metal powder, the helix being shortened by compression during the compacting of the powder between plungers 122, 123, Fig. 5. Instead of being formed wholly of alloy, the core may comprise a mixture of alloy particles and non- infiltratable particles of a larger size than the particles of the surrounding matrix. On sintering, the alloy infiltrates into the matrix, leaving a cellular structure in the space previously occupied by the core. The oil reservoir is filled by placing the bearing in oil in a vacuum tank or by boiling it in oil.
