Patent GB-730490-A (GB)
Abstract: 730,490. Rotary pumps. HOBOURN EATON MANUFACTURING CO., Ltd. Dec. 5, 1952 [Dec. 14, 1951], No. 30902/52. Class 110 (2). A rotary pump 10 forming part of a pumping unit 11 supplies fluid under pressure to a closed circuit 12, Fig. 1, which includes an accessory device 13 such as a hydraulic power steering device. Mounted on the unit 11 is a reservoir 16 to which the fluid from the circuit 12 is returned through an axial passage 19 in a member 18 which supports a strainer 20. The pump housing 22 is in two sections 22a, 22b, a rotor chamber 23 being formed in the section 22a. Arcuate intake and discharge ports 24, 25 communicate with the chamber 23, Figs. 1 and 3, the discharge port 25 being in communication only with the pumping chambers 35. Similarly, the housing section or cover 22b has arcuate intake and discharge ports 26, 27 communicating with the rotor chamber 23. A shaft 28 supported in bushings 29, 30 in the housing extends through a packing 31 and is adapted to be coupled to driving means. Within the chamber 23, a rotor member 34 is keyed to the shaft 28 and is in meshing engagement with an outer rotor member 33 supported by a bushing 36. An intake passage 38 connects the reservoir with the intake port 24 and the fluid is returned through a passage 15a leading from the return conduit 15 of the circuit 12. Between the intake and discharge ports 26, 27 is a valve chamber 39 containing a by-pass valve assembly 40 and communicating through a passage 42 with the discharge port 27. Beyond an annular valve seat 41 is a by-pass passage 43 through which by-passed fluid is returned to the intake side of the pump. The assembly 40, Fig. 5, controls the flow of fluid through the 'passage 43 and comprises a volume control valve member 46 and a pressure relief valve member 47. The valve member 46 has radial ports communicating with discharge port 27 and a plunger portion 50 co-operating with the annular seat 41, while a spring 52 in the delivery passage 45 tends to move the member 46 to the closed position. Radial by-pass ports 54 communicating with the valve chamber are provided in. the member 46 near a valve seat 53, which co-operates with the spring-pressed plunger 55. The passage 45 is connected with the discharge port 27 by a flow control orifice 59 in the member 47 and radial openings 49. When the pump is driven at high speed the resultant of the fluid pressure across the orifice 59 and the pressure of spring 52 opens the valve member 46 to by-pass pumped fluid from the discharge port, 27 to the passage 43 and return it to, the pump. The by-passed fluid passes from the passage 43 through an annular insert 61, Figs. 1 and 3, extending into the intake 38 and provided with a delivery opening 63 facing towards the intake port 24. The insert 61 is so dimensioned that the feed from the reservoir 16 flows round it and mlligles with the by-passed fluid, turbulence being.thus minimized. In a modification the rotary pump is provided with two rotor chambers axially spaced and parallel, an intermediate housing being provided which contains a valve chamber. Specification 719,359 is referred to.

Patent GB-2047940-A (GB)
Title: Autoreverse Tape Cassette Deck
IPC: G11B15/16
Filed: 1980-03-20
Abstract: The deck includes an arrangement for playing the preferential track when a cassette is inserted. In normal operation, a motion detector 5,1 switches to a high output when the take-up spool 5 stops and multivibrator 2 then produces an output to actuate relay R via transistor 6 and cause the tape to reverse. Switches S2 and S3 are controlled by a bistable member such that S2 is closed and S3 open when the tape is moving in the preferential direction and S3 is closed and S2 open in the other direction. When start switch S1 is closed the output of bistable 3 is reset to 0 via capacitor C. If S3 is then closed (non-preferential direction), OR gate 4 gives a 0 output to reverse the tape. S2 then closes to set bistable 3 and hold the OR gate output high. Thereafter capacitor 8 charges and bistable 3 cannot be reset until the cassette is ejected.   <IMAGE>
Patent GB-2075597-A (GB)
Title: Rotary air compressors
IPC: F04C29/02
Filed: 1980-05-02
Abstract: A rotary oil mist compressor has a rotor stator unit (10, 12) in which, in use, air is compressed and oil is injected into the air. A primary separation means comprising an impingement shield (24) around the stator separates the majority of the entrained oil droplets from the compressed air. Secondary separation means comprising one or more tubular filters (40) separate substantially the remainder of the entrained oil. The pathway between the primary and secondary separation means includes four substantially right angle bends, two of which are at the entry and exit of a secondary separation manifold (38) in which oil is coalesced by the acceleration and turbulence which occurs at each bend and then returned by the compressor pressure for re-use. The oil separation load on the tubular filters is thus reduced and the oil separation efficiency increased.

Title: Ignition timing control systems
IPC: F02P5/145
Filed: 1981-03-11
Abstract: The system comprises a pair of relays J1, J2 which control the connection to an ignition unit M of a respective one of two contact breakers M1, M2 thereby advancing or retarding the ignition timing in dependence on the position of the throttle. When the throttle is depressed, an earthed switch K engages a movable contact K2 to energise the relay J2 and enable one of the contact breakers M1 or M2 to be connected to the ignition unit. Similarly, if the throttle pedal is released, the other relay is energised via contact K1 to connect the other contact breaker to the ignition unit. <IMAGE>
