Title: Dual brake valves
IPC: B60T15/04
Filed: 1973-05-02
Abstract: 1378325 Dual brake valves CLAYTON DEWANDRE CO Ltd 2 May 1973 [2 May 1972] 20355/72 Heading F2F In a dual circuit driver operated brake valve, coaxial primary and secondary piston and valve assemblies are displaced to seal off respective circuit delivery ports from exhaust and to connect them to corresponding circuit inlet ports, whereby flexible pipes having portions curving around the axis of the valve provide the communication between the control valve of one assembly and its associated inlet and delivery ports. Upon driver depression of a cup member 9, biased by a graduating spring 10, an upper piston 3 of the primary assembly is depressed to cause a spring biased disc valve 11, which initially abuts a seat 12 of the piston 3, blocking communication between the primary inlet port 14 and the primary delivery port 15 via a flexible pipe 16, an annular chamber 4, an annular chamber 6, and a flexible pipe 17, to abut a seat 13 on the end of a lower piston 8 of the primary assembly thus blocking communication between an exhaust port 33 or ports and the delivery port 15. Subsequent movement of the piston 3 causes movement of the valve 11, of the piston 8, and of a piston 19 of the secondary assembly, the pistons 8, 19 being separated by abutments 32 which allow force transfer. Thus, the piston 19 abuts a corresponding disc valve 22 to achieve a similar sequence of events in the secondary assembly as in the primary assembly. Further movement of the piston 3 causes the disc valves 11, 22 to move away from respective seats 12, 24 to provide communication between respective inlet ports and delivery ports for the two circuits. Springs 34, 35 are chosen to provide simultaneous valve action of each assembly for minimal pressure differential between the circuits. The flexible pipes 16, 17 of the primary assembly extend axially from their associated ports 14, 15, then, in a plane normal to the valve axis, turn through 180 degrees, and then extend radially to their respective chambers 4, 6.

Abstract: 662,387. Control of several D.C. motors. SYNCRO MACHINE CO. Aug. 12, 1949. [July 29, 1949] No. 21055/49. Class 38 (iii). [Also in Group XI] Current is passed through a wire 16 to heat it to annealing temperature and passes over pulleys 13, 25, 28 on leaving a final drawing capstan 12 so as to synchronise the movements of the wire with its speed at the drawing capstan, the wire then passing to a winding spool 17. Current is fed to the wire from a tap 50 at one end of the secondary of a transformer by a wire 54 to the capstan pulley 12 and by a wire 58 to a pulley 28, the other end of the secondary being connected by a wire 56 to an intermediate pulley 25. The pulleys 25, 28 are driven by electric motors 27, 30 so that the speed at the peripheries of the pulleys is equal to the speed of the wire at the drawing capstan 12. A D.C. generator 64 is driven by a shaft of the wire drawing machine and its armature is connected to the armatures of the shunt wound motors 27, 30 as in Fig. 1. The field windings 60, 61 of these motors and the field winding 63 of the generator are connected through rheostats 75 to D.C. supply lines 70, 71. The armature of generator 64 is normally connected by a wire 78, normally closed relav switch C and lines 81, 82 to one side of the armatures of the motors 27, 30 the other side of which is connected to line 71, so that the rotation of the pulleys varies directly with that of the final drawing capstan, and the motors rotate at the same speed. At the initial starting, the voltage output of the generator 64 is too low to operate the motors and hence relays 80, 90 are actuated, closing switches A, B, A and opening switch C thus connecting the motor armatures directly across the D.C. supply lines 70, 71. When the generator 64 supplies sufficient current to operate the motors relay 90 connected across the generator armatures operates to open its switch A and breaks the supply to relay 80, whereby switch C is closed and switches A, B opened to connect the generator output to the motors 27, 30.
