Title: Anti-lock vehicle brake systems
IPC: B60T8/34
Filed: 1972-06-19
Abstract: 1413969 Anti-skid braking systems MULLARD Ltd 11 May 1973 [19 June 1972] 28585/72 Heading F2F  An antiskid braking system of the kind including a fluid pressure source such as a master cylinder or a continuously running pump, an anti-lock control valve, solenoid-operated by signals from a wheel movement sensing device, and a relief connection opened by the valve, when actuated, to allow displacement of fluid to relieve braking pressure, also includes a failsafe arrangement 1 comprising fluid flow inhibiting means biased to an inhibiting position and responsive to fluid pressures in the relief connection 18 so that with the antilock valve 5 closed fluid pressure above a predetermined value causes displacement of the flow inhibiting means to a position where it cannot impede flow through the valve 5 when the latter is actuated whereas with the valve actuated in the absence of fluid pressure, a pressure drop across the device 1 arising from a subsequent braking action causes the device to remain in the inhibiting position. The device 1 comprises a chamber 26 in which a piston 27 slids, an inlet port connected to the relief connection 18 and an outlet port 29 communicating with valve 5. The piston 27 biased by a spring 33 and slidable member 34 acts as a restriction adjacent port 29. As fluid pressure builds up when braking occurs piston 27 is moved against the spring 33. If the valve 5 is already energized, due to a malfunction, when braking occurs flow of fluid into chamber 26 and region 32 does not result in build up of pressure on the right hand face of the piston as there is flow through outlet port 29 and piston 27 is entrained therein to act as a restriction to further flow.

A demagnetizing coil is energized from an A.C. supply via two transformers interconnected by an electronic control network by which the coil current is maintained symmetrical and its amplitude may be progressively reduced. The coil, not shown, is connected to transformer 3 at terminals 2. The control network comprises a valve 13 and two germanium diodes 18, 19 connected as shown, so that each of two primary windings 7, 8 on the output transformer 3 carry current on alternate half-cycles. A compensating circuit 9, comprising variable resistors and capacitors, is connected between additional transformer windings 10, 11 to provide phase and amplitude correction for stray coupling between the various windings. As shown, the valve is used as a diode, the output being reduced by switching off the heater supply, but alternatively, a suitable voltage could be applied to a control grid 20. The output transformer 3 has a tapped secondary to suit a variety of demagnetizing coils.

Abstract: 932,058. Shaft kilns; recirculating combustion products. PRIEST FURNACES Ltd. Aug. 17, 1961 [Aug. 19, 1960], No. 28867/60. Classes 51 (1) and 51 (2). A limestone burning kiln, especially for small size limestone, with a rectangular shaft, contains upper and lower horizontal hot gas inlet flues in each side wall connected to the shaft by horizontal ducts; upper and lower horizontal waste gas outlet flues disposed above and below the lower hot gas flues, and connected to the shaft by horizontal ducts and to the inlet side of a fan; a horizontal waste gas flue in each side wall, connected to the outlet side of the fan and also to a furnace chamber; cold air inlets at the bottom of the shaft, and a horizontal flue for preheated air in each side wall above the cold air inlets, which is connected to the shaft by horizontal ducts and to a burner in the furnace chamber which is in turn connected to the upper and lower hot gas flues. As shown in Fig. 1, the kiln is heated by an oil burner 31 which receives preheated air through ducts 33, 34 and fan 30 from the flues 27, the air having been drawn in cold through openings 26 in order to cool the limestone in the air preheating zone 18. The hot combustion gases mix in the furnace chamber 21 with hot air drawn from the waste gas flues 44, 50 by the fan 24 and passed back across the shaft through flues 19. These gases are then passed into the limestone at the top and bottom of the burning zone 17 through flues 40, 35. At the top of the shaft are outlet ports 80 leading to waste gas pipes 81, an exhauster 82 and a stack 83, and also outlets 84 leading to draught stacks 85. The embodiment of Fig. 5 shows a kiln heated by blast furnace gas which is drawn in cold through an inlet 65 of a preheater 64, passing up through the preheater and out through a pipe 70, being heated by descending waste gases extracted from the kiln through flues 66 above the upper hot gas flues 40, which are then exhausted from the preheater. Preheated air from duct 27 mixes with the hot combustion gases in the furnace chamber 21, and the limestone is cooled by cold air supplied to flues 74 and ducts 73 by a fan, through pipes 75.

Abstract: 604,475. Winding &c. yarn. KINSELLA, E. Oct. 31, 1945, No. 28930. [Classes 120(ii) and 120(iii)] A traverse mechanism for a yarn winding machine comprises an intermediate lever 52, 53, means for connecting one part of the lever to a part of the machine to be traversed, means connected to another part of the lever for rocking it to and fro about a pivot to effect the traverse, and means for moving the pivot to and fro at a lower frequency to vary the field of traverse. As described, the traverse mechanism is applied to a ring spinning frame wherein the weight of the ring rail 14 is balanced by an air cylinder 23 the piston of which is connected by chains 26 to the traverse bar 15 connected by chains 16 to rods 19 attached to the rail 14. In its lowest position, the traversal of the rail is assisted by a spring in a cylinder 30 connected to a lever 32 engaged by a yoke 33 on the chains 26 when the rail reaches the bottom of its travel. The traverse bar 15 is connected to the rod 36 reciprocated by a cam 64 through a pivoted lever 75 and blocks 44, 49 slidable in guides 45, 48. The blocks 44, 49 carry pivoted members 47, 50 through which slide the ends of a lever 52, 53 pivoting about a pin 55 carried by a block 56 slidable in a guide 57 adjustably attached to the gear box 37. The block 56 carrying the pivot of the lever 52, 53 is moved slowly to and fro along the guide 57 by a cam 65 through a slotted lever 80 which is replaceable when a different type of package is required to be wound. By arranging the guide 57 parallel to the position of the lever 52, 53 (when in its end position) a package is formed wherein the yarn layers are of progressively decreasing length but all end in a plane perpendicular to the axis of the package. By arranging. the guide 57 horizontally (Fig. 2), the traverse will be of constant length throughout but will be displaced along the package. By arranging the guide 57 vertically (Fig. 2) the traverse will be of progressively decreasing length to give a package equally coned at both ends.
