Abstract: 732,085. Tyre-retreading devices. HAWKINSON CO., P. E. May 7, 1953. [Dec. 24, 1952], No. 12813/53. Class 87 (2). A tyre-retreading device comprises a cylindrical matrix 1 formed from sheet metal and having radially inwardly projecting endless tread material confining flanges 2 adjacent its opposite ends, a tubular heating element 14 coiled about the outer surface of said matrix and terminating in inlet and outlet heads adjacent the ends of the matrix, a circular tubular heating element 19, 20 wound adjacent to and secured to the axially outer side of each of said confining flanges and terminating in laterally outwardly projecting fittings and a flexible conduit 28 spanning the outer surface of the matrix and provided at its opposite ends with couplers each adapted to be detachably secured to one of its projecting fittings. On the outside of the matrix is sheet metal reinforcement 10, with its ends crimped over the edges of the matrix, round which the heating element 14 is wound, with reinforcing bands 15 between the turns of the heating coil. Rings 6 are welded to the V-shaped confining flanges 2 to form in effect extensions of their inner walls which provide nests for the inner turns 19 of the flange heating elements, to one of which steam is admitted through a pipe 26. After circulating through the first flange heating. element the steam leaves its outer coil 20, passes through the flexible conduit 28 to the outer coil 20 of the second flange heating element, and leaves the second inner coil 19 through a pipe 30. The confining flanges are thus heated independently of the rest of the matrix, for a same or different length of time, or, by contrast, cold water may be circulated through the elements 19, 20 to prevent over-curing the sides of the tread. On the inside of the matrix tread design-forming projections 8 are screwed or welded. Circumferential rails 13 project from the outer surface of the reinforcement 10 to facilitate rolling of the matrix without damaging the heating element 14. Specification 420,829 is referred to.

Title: Braking rail vehicles
IPC: B61H7/02
Filed: 1930-04-28
Abstract: 353,942. Fluid-pressure brakes. MALEY, A. W., 4, Grosvenor Road, and TAUNTON, E. M., 11, Wilton Road, both in Handsworth, Birmingham. April 28, 1930, No. 13033. [Class 103 (i).] Pneumatic wheel and track brakes are applied in different positions of a driver's handle and in an intermediate position, the release position, a quick release device is set in action by which the wheel brake cylinder is connected to exhaust. In one arrangement the release valve is closed by a diaphragm acted on by the pressure-fluid which thereafter flows to the wheel brake cylinder through a restricted aperture in the first position of the handle which can then be moved to a lap position between the wheel brake position and the release position to hold the brake on. When the handle is moved to or past the release position the pressure on the release valve piston falls and a spring and the brake cylinder pressure opens the release valve, thereby directly connecting the brake cylinder to atmosphere. In a modification the release valve 4 is also provided with a valve closing the wheel brake cylinder 5 from the supply pipe 1. The driver's valve comprises admission and exhaust valves 31, 32 respectively for the track brake and admission and exhaust valves 35, 36 for the wheel brake. The cam 38 on the spindle of the brake handle 39 is arranged to lift the valve 36 only partially so that a spigot portion 37 restricts the valve opening to somewhat less than that afforded by the restricted opening 9 to the brake cylinder 5 so that the valve 4 will not be opened to exhaust. The quick-release valve may have a lap position and comprises separate valves operated by a piston 11 and a lever 12. Movement of the driver's handle temporarily to slow exhaust position recloses the admission valve 14 without opening the exhaust valve 13 to obtain a lap position. A quick-release valve is also shown having a stop valve which provides a lap position. The pistons of the release valves may normally be under pressure and application of the brake result from release of the pressure on the piston, for instance in case of accident. The invention may be applied to vacuum brakes. Specification 294,593, [Class 103 (i), Brakes &c.], is referred to.

Abstract: A wire strand or rope is drawn through reducing means whilst applying a uniform back-tension thereto, the strand or rope emerging from the reducting means being subjected to a heat treatment stage while still under tension.  The reducing stage deforms the round wires of the strand or rope until they interfit in line contact with each other. The heat treatment is effected at a temperature of 200 DEG C.-400 DEG C. and is followed by a cooling stage.  The reduction in cross sectional area in the range 4% to 80% and the back tension is in the range 2% to 65% of the breaking load of the strand or rope.  Heating may be by induction.  The strand or rope is coiled after the cooling stage and the degree of cooling is such that the strand or rope does not take a permanent set when it is coiled.

Title: Electronic timepieces
IPC: G04C9/08
Filed: 1976-04-01
Abstract: 1512613 Electronic timepieces DAINI SEIKOSHA KK 1 April 1976 [3 April 1975]  13197/76 Heading G3T An electronic timepiece is provided with a single setting switch which is held closed for more than one second, to retard the time displayed, and which causes the display to advance one step each time it is held closed for less than one second. In Fig. 1, a quartz crystal controlled oscillator circuit 1 feeds a 32768 Hz signal to a frequency divider chain 2. A timing reference pulse train at 1 Hz and appropriate width is produced by a waveforming gate circuit 3 which combines the outputs of divider stages F 1  0 -F 1  5 . In normal operation the timing signal is applied via an inverter 10 and a NOR gate 11 to a time measuring and displaying means 12, e.g. a stepping motor driving hands- OPERATION. To advance the time displayed, a setting switch 13 is closed for less than 1 second a logic "1" signal is fed to the NOR gate 11 by anti-chatter switching circuit 16. NOR 11 consequently cuts off the supply of the timing reference signal to the display. A counter 27 starts to count pulses of the 32 Hz output of divider stage F 1  o and would produce an output pulse at Q on reaching a count of 32 but is reset at the termination of the signal from switching circuit 16 before it reaches a count of 32. Thus outputs of counter 27 and a resetting circuit 28 will remain at "0". At the instant the said signal from 16 terminates, a first pulse generator 34 sets a flip-flop 41 the output of which after inversion at 44 controls AND gates 4 to 7. Consequently a logic "1" correcting pulse P 1  is produced by a NOR gate 9 as soon as the output from divider stage F 10  goes to "0". The pulse P 1  is inverted at 10 and applied to the time display means 12 via the NOR gate 11, the other input of which is logic "0" since the signal from switching circuit 16 had previously terminated. As soon as P 1  ceases, a second pulse generator 45 resets flip-flop 41 and all the circuits resume their normal state. Thus each closure of switch 13 of less than 1 second duration, causes the display to advance one step. To retard the display, switch 13 is closed for more than one second so that the counter 27 will produce an output at Q at the count of 32 and the resetting circuit 28 will reset the divider 2. The timing reference signal Pb is blocked by NOR gate 11 since one input thereof is maintained at "1" by the signal from switching circuit 16. Likewise a pulse produced by waveforming circuit 3 when the divider is reset is also blocked from the display means. Thus while switch 13 is closed the display will not advance. Normal operation is automatically resumed 1 second after switch 13 is opened.
