Title: Improvements in or relating to braking systems
IPC: B60T8/74
Filed: 1939-08-11
Abstract: 536,487. Fluid-operated braking systems. BUDD WHEEL CO. Aug. 11, 1939, No. 23210. Convention date, May 1. [Class 103 (i)] A vehicle braking system particularly for railway vehicles, comprises a member movable in response to variations in braking torque, the system operating to prevent additional braking action when the torque has developed to a predetermined value which is made to vary with the control pressure or with the rate of change of velocity of the vehicle. In the construction shown in Fig. 1 a brake application valve A receiving the control pressure from line 14 is closed upon completion of an electric circuit by apposition of contacts 48, 49 produced by the movement of a part 61 relatively to the contacts which move under the action of a piston 58 subjected to the control pressure, the movement of the part 61 being produced by means of an arm 34 moving in accordance with the torque produced ; if the torque continues to increase, after closing of the valve A, sufficiently to bring another pair of contacts 54, 55 together to close a second electric circuit, a brake release valve R is opened to exhaust in order to release the brakes. The contacts are duplicated as shown in order to obtain similar control when the vehicle direction is reversed. In order to be able to apply different brake pressures to the two sets of brake cylinders 10 a variable leverage system is associated with one of the relay valves 12, 12a for operating the brake cylinders. In modified constructions the torque arm itself carries the contact-operating parts, the control pressure acting through pistons being balanced against the applied torque. The brakes are additionally controlled against wheel-sliding by means of a separate set of contacts for operating the brake application and release valves. In another construction the contacts are movable in accordance with the vehicle deceleration.

Title: Improvements in or relating to a hydraulically operated controlled stroke gun head
IPC: B21J15/06
Filed: 1965-06-01
Abstract: 1,097,343. Blind riveting machines. TEXTRON INDUSTRIES Inc. June 1, 1965 [June 8, 1964], No. 23322/65. Heading B3U. A blind rivet setting tool first draws the mandrel 1 into the rivet while the reaction force is applied to the head 10 of the rivet, then transfers the reaction force to a locking ring which is swaged into a recess 4 in the rivet head and applies a further pull to break the mandrel. The mandrel 15 is pulled by a piston 24, the piston-rod 23 of which is attached to a collet 16 which contains gripping jaws 12. The jaws 12 are closed by conical faces 19 on the collet 16 under the action of a spring 30. The broken mandrel is ejected by a spring loaded pin 17. During this pull the reaction force is transmitted through the tubular body 1, having an anvil 4, to the head 10 of the rivet. The pulling is terminated when a valve stem 67 on the piston 24 engages on adjustable stop secured to the end cover 33 of the housing 32. Movement of the valve stem 67 allows pressure fluid to flow along a conduit 68 in the valve stem 67 through the hollow stop 58 and along a passage 77 to a space 78 behind the end 44 of a shift piston 31, causing the piston 31 to move to the left (Fig. 3). The piston 31 engages a tubular sleeve 2 which moves an anvil 3 which contacts the locking ring and thus transfers the reaction force to the locking ring. Further movement of the piston 31 causes the anvil 3 to engage the end 4 of the tubular body 1, which can slide in the end cap 37 of the housing 32, thus causing the tubular body 4 and anvil 3 to move relative to the pulling means to break the mandrel.

Filed: 1929-07-30
Abstract: 333,377. Farrand, H. A. July 30, 1929. Measuring-tapes.- Relates to means for coiling and controlling t h i n spring tapes, such as measuring-tapes, which are curved transverselv in cross-section, and which tend to become straight when uncoiled. The spring tape x is wound exteriorly as upon a barrel 6, Figs. 3 and 4, turned by a crank 8. The barrel 6 is supported in a box 1 with a pivot bolt 10 at one edge upon which is pivoted a lever 11. A shoe 13 upon the lever 11 is pressed by a spring 15 hard upon the tape x so as to flatten it. The spring winds into a flat spiral and is held against unwinding. On depressing lever arm 14, the tape spring unwinds itself into a straight band. In a modification, the holding means is a spring band of C-shape which encircles the coiled spring and presses inwards upon i tby multiple rollers. In a form shown in Fig. 7, the tape x is coiled on barred 6b by turning crank 8b, the coils being formed inside a C spring 24<b> between side lugs 22<b>. The ends of spring 24b are secured to levers 26 which have a slot connection at 28. When the ends 27 of levers are pressed together, the spring tape x uncoils automatically.

Title: Surge Arrester
IPC: H01T1/14
Filed: 1968-05-16
Abstract: 1,172,345. Surge diverters. SIEMENS A.G. 16 May, 1968 [22 Sept., 1967], No. 23449/68. Heading H2H. A surge diverter includes a current-sensitive element which breaks the circuit through the diverter when the current is excessive. In the embodiment shown, a surge in a conductor connected to terminal 3 of the diverter can escape to earth through terminal 28 by breaking down a spark gap 14 between two copper discs 6, 8. The current flows by way of a voltagedependent resistance diso 10 and a disconnecting device 21 which includes a soldered joint 20 and a fusible wire 23. The wire may be in the form of a strip. When the surge has been dissipated, the spark gap 14 should be automatically restored, but if this does not occur, the small current still flowing heats the disc 10 and softens the joint 20 so that a spring 27 pulls a pin 18 from the joint and breaks the circuit. Too large a surge current may destroy the disc 10, and in this case the wire 23 fuses rapidly to break the circuit more quickly than could the soldered joint 20. In order that a small current should cause disconnection at the joint 20 rather than at the wire 23, the minimum response current of the wire must be higher than that of the joint.
