Abstract: 439,953. Time switches. GUNNING, J. R. W., 100, Holdenhurst Road, Bournemouth. June 13, 1934, No. 17493. [Class 38 (v)] A time switch comprises a lever 1 pivoted at 8 which carries an insulating block 6 on which are mounted two contact studs 4, 5 connected by a conducting strip 7. When an " on " tappet 3 engages a sloping surface 9 on the lever 1 it is turned against a spring until the contact stud 4 engages a contact stud 10 mounted on a spring arm 11. At this point an insulating block 15 pivoted on the block 6 engages the end of a pivoted spring biassed lever 12 to move a contact 13 out of the range of contact stud 5. On further movement the block 15 slips past the end of arm 12 which returns rapidly and circuit is completed at studs 13, 5. The tappet 3 causes still further depression of the arm 1 before it passes off the end of the slope 9 and this gives a wiping action to the contact surfaces. The arm 1 is latched in its on position by the engagement of a pin 9<a> on the lever 1 with a spring biassed lever 18 which is later released by an " off " tappet 2.

[Class 37] In apparatus for determining the high frequency resistance of braided cable the outer braids of a pair of cables 26 forming a dual line are , short-circuited at one end by a metal clamp 20 the outer surfaces at the other end being attached to metal rods 32 which enable the cables to be held taut by wing nuts 34. A short-circuiting bar 36 is adjustable along rods 32 by rotating a threaded rod 42. Energy is supplied to the cables by means of a coupling loop 46 fed from a H.F. oscillator having a frequency such that the distance between metal clamp 20 and the slidable bar 36 is one half wavelength. A vacuum tube voltmeter 48 is connected to the cables at one quarter wavelength distant from the clamp 20 and the position of the bar 36 adjusted until the reading of the voltmeter is a maximum. The slidable bar 36 is moved first to one side and then to the other until, in each case, the reading is .707 of the maximum, the distance between these two positions of the bar being noted. The process is repeated using comparable silver-plated conductors, and calculations based on a formula given, determine the resistance in both cases. That of the silver-plated conductors is almost entirely radiation resistance', and its subtraction from that of the cables under test gives the conductor resistance for these cables.

Abstract: 1456142 Anti-skid brake valves MIDLANDROSS CORP 25 April 1974 [18 June 1973] 18187/74 Heading F2F In an anti-skid valve assembly which has a solenoid operated control valve controlling a relay valve which cuts off flow in a brake line on receipt of a brake signal, a plunger 140 provides a passage restrictor to restrict a passage 74 connecting a control inlet 114 with a chamber 106 for operating the relay valve in the presence of air at the inlet, the restrictor being independent of the element 98 of the control valve, a logic chamber 128 influencing the plunger and in turn being influenced by a oneway check valve 120, 122 normally closed to isolate the chamber 128 from the passage 74, but movable to an open position when the element 98 is in receipt of a skid signal. For braking under non-skid conditions, air is supplied by a treadle valve to the valve assembly, Fig. 3; the air flows in the passage 14 to the chamber 106 therein, and then to a chamber 31 above a piston 30 of the relay valve, Fig. 2, to move the latter downwardly to initially close off communication between an exhaust outlet 46 and a brake delivery port 62, and then initiate communication, by moving a flange 48 from a seat, between the delivery port and a pressure inlet port 66 for brake actuation. Upon receipt of a skid signal, a computer actuates a solenoid plunger 86 in a fixed armature 78 to move a stem 94 downwardly shutting off communication between the bore 74 and the chamber 106 by means of the element 98 and opening the chamber 106 to an exhaust port 88, actuating the relay valve for brake release. Simultaneously the one-way check valve 120, 122 is opened by such stem movement to open the chamber 128 to inlet pressure causing the plunger 140 having a stem 141 to restrict air flow through the bore 74. A minimum flow is achieved by a groove 146 in the stem 141. When the skid condition is removed, by the associated wheel accelerating to vehicle speed, the solenoid plunger 86 is deactivated for the chamber 106 to be exposed to pressure in the bore 74. Initially air from a cavity 118 allows pressure build-up as rapidly as before but the restriction slows the subsequent rate of increase. This action occurs for all subsequent brake application cycles. Upon deactivation of the treadle valve, a one-way check valve 136 allows air to return from the chamber 128 to the treadle valve. The check valves 120, 136, and the plunger 140 can be tested by application of pressure in the bore 74 to overcome the force of a spring 124 biasing the valve 120 to fill the chamber 128 and move the plunger; subsequent release operates the valve 136.
