Title: Improvements in or relating to centrifugal fan embodying airfoil blades
IPC: F04D29/68
Filed: 1957-12-04
Abstract: 841,164. Centrifugal fans. WESTING- HOUSE ELECTRIC CORPORATION. Dec. 4, 1957 [Dec. 10, 1956], No. 37731/57. Class 110 (1). A centrifugal fan impeller comprises backwardly-curved aerofoil blades having slots in their gas impacting sides, near their trailing edges, gas being supplied under pressure into the blades and discharged through the slots at an angle of between 30 and 120 degrees to the camber line of each blade, whereby the gas deflects the main gas stream outwardly from the trailing edges. The discharge pressure of a centrifugal fan can be increased by blowing compressed air from the interior of each impeller blade 11A, Fig. 6, through a slot 24A situated near the trailing edge of the pressure or convex side of the blade, so as to deflect the main air stream outwardly from the trailing edge. The slot 24A, the width of which is preferably between 0.5 and 10% of the chord length of the blade, is at an angle # of between 30 and 120 degrees to the camber line. The compressed air may be supplied from an external source, passing through the hollow impeller shaft and thence through radial passages in the centre plate or back-plate of the impeller to the blade interiors, as described in Specification 780;464. Alternatively, the compressed air may be supplied by an auxiliary centrifugal fan attached to the impeller backplate, the flow being controllable by a cylinder concentric with the impeller shaft and movable axially to obturate the eye of the auxiliary fan to a variable extent, as described in Specification 758,906. Further alternatives are shown in Fig. 7, in which air is forced by ram action into the interior of a blade through a slot 40 in its leading edge. This slot may instead be situated in the pressure side of the blade at a short distance from the leading edge, with a lip 42 to act as a scoop. Reference has been directed by the Comptroller to Specifications 758,906 and 780,464.

Title: Hydraulic apparatus
Inventor: BOWERS ERIC HIDER
IPC: F16H47/02
Filed: 1960-11-10
Abstract: 978,661. Hydraulic transmission of power; valves; change-speed gear and control. DOWTY HYDRAULIC UNITS Ltd. Nov. 6, 1961 [Nov. 10, 1960], No. 38696/60. Headings F2C, F2D and F2V. An hydrostatic power transmission comprises a pump 2 and motor 5 connected in series with and in front of a mechanical changespeed gear 7 for the transmission of power from a source 1 to a load, such as the road wheels of a vehicle, and an hydraulic slipping means 33 for permitting slip between the pump and motor to limit the shock loading which might occur on change of mechanical speed ratio. The pump, which may be of the reversible variable positive displacement type, is connected by pipes 3, 4 to the positive displacement motor which may also be variable and has a coupling 6 to a shaft 8 having gears 9, 11 selectively engageable with gears 15, 16 on an output shaft 12. The gears 15, 16 are carried by a sleeve 17 movable by a lever 19 having a lost motion connection 23, 24 with a hand lever 22 formed with a cam 25 which, when the lever is moved from an end position to take up the lost motion, displaces a piston 61 and a rod 66 to unseat a ball valve 55. The unseating of the ball valve connects the space to the left of a piston 44 to a passage 58 leading to a reservoir 27 so that the compression of a spring 47 retaining a valve 48 on a seating connected by a pipe 34 and oneway valves 35, 36 to the pipes 3, 4 is reduced; the valve 48 can then lift as the pressure in pipe 3 or 4 increases to a relatively low pressure, say, 1500 1bs./square inch, as a result of shock to the transmission when the lever 22 is moved further to change the gear ratio. The liquid discharged past the valve 48 flows through passages 41, 42 to a line 28 connected by oneway valves 31, 32 to the pipes 3, 4 to make up for the liquid discharged. When the lever 22 is moved to its furthest position, the cam 25 is disengaged from the rod 62 of the piston 61 to permit the piston to return at a slow speed determined by a throttle 67 and provide a time delay before the ball valve 55 engages its seating and liquid from the line 41, which is connected to a make-up pump 26 also connected to the line 28, passes through a restriction 52 to move the piston 44 to the right whereby the compression of the spring 47 is increased to retain the valve 48 on its seating except if a relatively high pressure, say 5,000 1bs./square inch occurs in pipes 3 or 4. In an alternative embodiment, the ball valve 55 is opened by movement of the piston 61 as before to permit the valve 48 to open at the lower pressure but the valve 48 is hydraulically locked in the closed position when the ball valve is closed and a separate high pressure relief valve is provided. The changespeed gear may comprise a plurality of gear trains constantly in mesh and engaged one at a time by friction clutches.
