Title: Safety mechanism for vehicle brake installations
IPC: B60T17/22
Filed: 1971-09-20
Abstract: 1307479 Brakes DR ING hcF PORSCHE KG 20 Sept 1971 [18 Sept 1970] 43829/71 Headings F2E and F2F In a two-circuit brake installation, each brakelining carrier is actuated by two cylinders 1, 2 which are normally separately operated by tandem cylinders 6, 7 via lines 3, 4. These lines are normally fed from lines 11, 12 through grooves 36, 37 in spring loaded control pistons 16, 17. These pistons normally receive pressure at each end from each supply so that they remain balanced and do not move. At the same time differential pistons 14, 15, each of two diameters, are likewise balanced by pressure at the ends matched by pressure at the middle. When one system fails so that its pressure - collapses, the differential piston still having pressure at its large outer end, moves to the left because there is no counterbalance pressure at its middle from the other circuit. This concentrates the pressure at the end of smaller diameter and feeds an extra pressure to the remaining active brake cylinder, 1 or 2. The extra pressure fed to the left-hand end of piston 14 or 15, together with the failure of pressure at its other end from the other circuit, causes it to move to the right. This closes off the grooves 36, 37 to prevent leakage back of the pressurized fluid now acting in the surviving circuit. At the same time it closes a switch to energize warning light 44 or 45 as the case may be. As shown the rear wheels also have a two-circuit energization, but they may have only a single circuit (Fig. 1, not shown). The control pistons may be moved by electromagnets 46 energized from pressure detectors 47.

Title: Improvements in and relating to thermoplastic moulding compositions
Inventor: ENNOR KENNETH STAFFORD
IPC: C08L33/12
Filed: 1961-12-08
Abstract: A thermoplastic moulding composition comprises a mixture of (A) polymethyl methacrylate or a copolymer of methyl methacrylate with less than 40% by weight of units of a monoethylenic comonomer, and (B) a rubbery homopolymer or copolymer of butadiene present in the mixture in an amount of 1.5% to 5% by weight. Comonomers specified for use in polymer (A) are styrene, alkyl styrenes, halo-styrenes, acrylic and methacrylic nitriles and amides and lower alkyl acrylates. Comonomers specified for use with butadiene are acrylonitrile, styrene and methyl methacrylate. The mixture of the two polymers may be made by the following methods: (i) by mixing latices of the two polymers and removing the water, (ii) by mixing one polymer in dry form with a latex of the other polymer, and removing the water, (iii) by masticating both polymers together in dry form, and (v) by polymerizing methyl methacrylate-containing monomeric material in the presence of the rubber. In the example polymethyl methacrylate and a butadiene/acrylonitrile copolymer are milled together.

Abstract: 1,236,116. Automatic speed control. HITACHI Ltd. Sept. 12, 1969 [Sept. 16, 1968], No. 45227/69. Heading G3R. A speed control system for lifts comprises a device SO providing a voltage corresponding to a pattern speed irrespective of the lift-position during the acceleration period, the said voltage being reduced in a stepped manner with the aid of a position detector POS operable when the lift arrives at any one of a number of pre-set deceleration-points. A comparator CP, which is saturable in the positive and negative directions, is connected to an integrator I providing negative feedback to the comparator. The integrated output is also supplied to a speed control system for the lift. A changeover relay RY1 passes the command signal alternatively to the comparator CP during the acceleration period, and to an amplifier AP1 during the deceleration period. The amplifier AP1 is connected to a tachometer generator PG, and supplies a speedcorrecting signal to the integrator I whose output is applied through amplifier AP2 to the field winding of a Ward Leonard generator G associated with the lift-motor M. In a modification, a clamping circuit is connected to the output of the amplifier AP1 to provide a dead band effect, Fig. 2 (not shown). The amplifier AP1 may have a saturation characteristic to limit the rate of deceleration, Fig. 4 (not shown).
