Title: Metering Valve Assembly for Automotive Braking System
IPC: B60T11/34
Filed: 1968-06-14
Abstract: 1,192,868. Hydraulic brakes; valves. MIDLAND-ROSS CO. 14 June, 1968 [31 Aug., 1967], No. 28458/68. Headings F2F and F2V. A valve for initially reducing the braking pressure applied to the front brakes of a vehicle relative to that applied to the rear brakes, comprises a chamber 28 having inlet and outlet ports 16, 23, a valve seating 22 surrounding the inlet port towards which a two-part sealing element 38, 39,is urged by a spring 46, and a piston 26 which is biased towards spring 46 which it supports by a further spring 33, the arrangement being such that the difference in pressure at the inlet and outlet is decreased in proportion to the inlet pressure and reduces to zero at a predetermined inlet pressure. Additionally, the provision of the two-part sealing element, comprising a flexible apertured rubber disc 38 and an apertured backing disc 39, provides a one-way valve to equalize pressure on brake release when the chamber pressure exceeds the inlet pressure; the chamber pressure acting through apertures 45 to lift the flexible disc 38 away from disc 39. In use, when the master cylinder 18 is initially pressurized, no pressure is transmitted to the front brakes until the fluid inlet pressure increases sufficiently to overcome the bias .of. the spring 46. Subsequently, with the pressure in chamber 28 increasing, the piston 26 is gradually moved against the reaction of spring 33 to thereby permit the spring 46 to extend and so decrease its biasing force on the sealing element 38, 39. In this way the pressure transmitted to the front brakes increases in constant proportion to that applied to the rear brakes until the inlet and outlet pressures equalize.

Abstract: 694,201. Cable making machines. SOUTHERN UNITED TELEPHONE CABLES, Ltd. Nov. 21, 1951 [Nov. 22, 1950], No. 28564/50. Class 36. Apparatus for applying insulating discs to a wire comprises a carrier to receive and feed the axially apertured discs one at a time, edge on to the wire, and a cutting device which is movable across the path of a disc in the carrier during the feeding movement and the leading edge of which makes a radial slit in the disc before the feeding movement begins. A rotating wheel 1 carries three regularly spaced wedge-shaped cutters 2 having radially extending cutting edges 3. The cutters move in the opposite sense to the wire 4, which engages in a slot 5 in the outer face of each cutter 2. The wheel 1 also carries a cam 6 which gives reciprocating radial movement to one end of a carrier 7. An insulating disc 9 passes down a vertical shoot, Fig. 2 (not shown), into a slot 18 in the end of carrier 7 and is held in position by the inner concave face 20 of a peripheral upstanding projection on wheel 1. The carrier has a horizontal slot for the passage of the cutter 2 and to permit wire 4 and disc 9 to be brought together. A vertical surface 11 on the carrier is held against the cam surfaces by a spring 12. When the surface 11 is against cam surface 23, the carrier is stationary and the leading edge 3 of a cutter 2 makes a radial slit in disc 9, the slit being expanded by the wedge-shaped rail of the cutter as the carrier begins its movement, on surface 14 of the cam, towards the wire. The carrier continues on this surface until the cutter passes out of the path of the disc and the expanded slit slips over the wire 4, when the surface 11 slips over point 15 on to the retraction surface 16 of the cam. The disc is no longer restrained by the carrier and moves away on the wire, while the next disc falls into position in the carrier. Discs may be applied from opposite sides of the conductor by two synchronously driven arrangements.
