Title: Vented filter assembly
IPC: A61M5/165
Filed: 1978-07-06
Abstract: A vented filter assembly 15 comprising a closed housing having a fluid inlet 44 and a fluid outlet 41. The housing includes an internal passage connecting the inlet and the outlet. A fluid filter is disposed within the passage between the inlet and outlet thereby defining an upstream pressure section between the inlet and the filter and a downstream pressure section between the filter and the outlet. A gas vent located in the housing is adapted to allow gas but not fluid to pass from the upstream section of the passage out of the housing. All fluid passing from the inlet to the outlet passes through the fluid filter.

Title: Vehicle hydraulic systems
IPC: B62D5/09
Filed: 1978-08-22
Abstract: A fluid-flow control system comprises a control circuit 4 and a power circuit 5 for supplying fluid to a motor 1 (for example a steering cylinder). Control valves 20, 22, 35, 37 are arranged in the supply and return sides of each circuit, each valve being controlled in dependence on the pressure drop across it. A regulating valve 23 is operative to ensure that the pressure of fluid in the supply side of the power circuit bears a controlled relationship to the pressure of fluid in the supply side of the control circuit. The excess pressure fluid which is usually diverted to tank when the pressure regulating valve is in its neutral condition is utilized by providing an auxiliary circuit 8 and a priority valve 49 which controls fluid flow to that circuit and to the other two circuits in dependence on a pressure drop at an orifice 18 in the control circuit. <IMAGE>
Patent GB-2036487-A (GB)
Title: Switching Circuit
IPC: H03K17/10
Filed: 1978-11-17
Abstract: At least one further semiconductor junction (24) is connected in series with the emitter of a switching transistor (17) to increase the switching voltage capability. Inverse collector current is prevented by a common base control transistor (21). When 12V is applied to terminal 20, collector current saturate from 21 saturates 17, 24 effectively earthing terminal 15 to intercept the bias to tapehead 11. When the 12V is removed, collector circuit from 21 ceases, turning 17, 24 off to generate an effective open circuit for voltages of either polarity at 15. When 15 is negative the collector/base of 24 is reverse biassed, and when 15 is positive the collector base of 17 is reverse biassed, but in neither case are the base emitter junctions forward biassed, so preventing current flow. A further embodiment substitutes a diode for transistor 24. <IMAGE>

Patent GB-2058231-A (GB)
Title: Variable pitch marine propellers
IPC: B63H3/00
Filed: 1979-09-07
Abstract: A variable-pitch marine propeller comprises helicoidal blades 6 each mounted on a hub 1 to freely pivot about radial axis 25 spaced in front, in the direction of rotation, of the center of pressure of the blade 6 whereby water pressure acting on the blade exerts a torque which tends to turn it about its axis in a direction to bring the surfaces of the blade into line with the flow of water over it. The axis 25 is also spaced behind, with respect to the direction of movement of the propeller through the water, a major portion of the pressure surface of the blade whereby, the resultant of the drag of the water exerts a torque which tends to turn the blade in an opposite direction. The shape and mass distribution of the blades relative to their pivot axes are also such that centrifugal effects tend to move the blades, in the absence of hydrodynamic forces, into a pitch equal to that of the helicoid. In operation each blade adopts a stable equilibrium position in which its pitch is optimally suited to the speed of rotation and the linear axial speed of the propeller.
