Abstract: 1,077,844. Fluid-pressure servomotor systems. AMERICAN BRAKE SHOE CO. Aug. 4, 1964 [Aug.9, 1963], No.31191/64. Heading G3P. A torque control apparatus for a swashplate pump or motor comprises a valve 84 loaded by springs 95, 103 towards the right and controlling the supply and exhaust of fluid through a passage B to act through ports 114 on a piston 86. The swashplate is adjusted by a lever 60 and the highpressure line is connected to a groove 93 and flows past grooves on the right hand load of valve 84 to act to move the valve to the left. When the back-pressure in the high-pressure line increases due to an increased load, the valve 84 moves to the left against the spring-loading and supplies fluid to act on piston 86. Movement of the piston 86 to the right reduces the angle of the swashplate to reduce volume of delivery and increase the delivery pressure. This adjustment compresses the springs 103, 95 to recentre the valve 84. A decrease in pressure moves the valve 84 to the right and fluid from the piston 86 escapes past grooves in the left hand load of valve 84. The valve seat 78 is adjustable to vary the setting of the swashplate.

Title: Improvements in and relating to tide operated air compressors
IPC: F03B13/26
Filed: 1921-11-22
Abstract: 191,239. Knight, H. M. Nov. 22, 1921. Tidal energy, utilizing.- Apparatus for utilizing tidal energy through the production of compressed air comprises vacuum-operated means for elevating a quantity of water so as to give a head additional to that due to the difference in levels on the opposite sides of a barrage across a tidal estuary. The water so elevated flows through a head 71, Fig. 2, and down a passage 73, entraining air with it to a chamber 34, where the compressed air separates from the water which passes on to a tail race basin 36, protected from wave action on its seaward side by a breakwater. The compressed air passes through a conduit 84 to a heating apparatus 86, and thence to the high-pressure cylinder 88 of a compressed air engine. The exhaust then passes through a freezer 91 which serves to remove moisture therefrom, and through the heating apparatus to the low-pressure cylinder of the engine, being exhausted to a tank 99 connected to a vacuum pump driven by the engine. The water-elevating apparatus is carried by pontoons 42 in a basin 41 and comprises a casing 68, Fig. 10, divided into two chambers communicating at the bottom through an aperture 52, in a partition 51, and at the top through pipes controlled by a valve 59, operated by a float 54, the valve also controlling a communication between the float chamber and the atmosphere, and the other chamber being connected through a pipe 78 with the vacuum tank 99. The elevated water periodically flows through siphons 67 to the head 71. An initial supply of compressed air for driving the engine and producing the vacuum is obtained in the chamber 34, by means of a head 30 in a basin 29, a pipe 32 leading to the chamber, and a pipe leading to the tail-race basin. The barrage is provided with openings containing leaves 10, Fig. 9, mounted on trunnions 11, the leaves being normally held from opening by projections 24 on rack bars. At the turn of the tide, the rack bars are operated to free the leaves and allow them to open to equalize the levels on the opposite sides of the barrage.

Abstract: 832,360. Axial-flow compressors and turbines; gas - turbine jet - propulsion plant. POWER JETS (RESEARCH & DEVELOPMENT) Ltd. Aug. 15, 1957 [Oct. 15, 1956], No. 31271/56. Classes 110 (1) and 110 (3). One end of a fluid-flow ducting is arranged as a row of separate adjacent passages for fluidflows, alternate passages of the row at the one end being brought together at the opposite end of the ducting as a row of separate adjacent passages, and the passages interleaving the alternate passages at the one end being brought together at the opposite end as another row of separate adjacent passages. Annular ducting for introducing two flows into an axial-flow compressor stage is shown in developed form in Figs. 1 and 2 and comprises inner and outer annular walls 17, 18 (not shown in Fig. 1), and an intermediate annular wall 10 which separates the two flows. The outer flow passage is divided by radial walls 11 into a peripheral series of passages 12, and the inner flow passage is divided by radial walls 13 into a peripheral series of passages 14. The walls 13 are peripherally staggered in relation to the walls 11, as shown in Fig. 2. The walls 11 and 13 intersect outer and inner walls 15 and 16 respectively, the walls 15 and 16 sloping and tapering as shown to meet the wall 10. The walls 11 and 13 may be faired into the walls 15 and 16. Adjacent walls 15 and 16 are connected by walls 19 which have radial outlet edges and circumferentially-extending inlet edges which merge into the outlet edge of the wall 10. The ducting may vary in radial height and in distance from the axis and may be helically twisted to accommodate whirl components of motion in either flow, and the separating walls may be non-radial. The flow areas of the two passages may differ and may vary from inlet to outlet. Where the ducting is used to introduce a second flow into an intermediate stage, the flow which has already passed through the earlier stages can have its whirl component removed by blading before entering the passages 14, the additional flow being introduced to the passages 12 through a coaxial annular duct. The ducting may be used for dividing a flow into two partial flows, and in this case is traversed in the opposite direction to that shown by the arrow in Fig. 1. It may be used in this way to divide the flow leaving an axial-flow turbine stage or for separating the air compressed by the intake fan of a by-pass jet propulsion engine into two streams, one passing into a by-pass duct and the other passing to the main compressor, combustion system and turbines.
