Title: Signal Transmission Circuit
IPC: H04B3/60
Filed: 1968-05-01
Abstract: 1,170,049. Track circuit signalling. WESTINGHOUSE AIR BRAKE CO. 1 May; 1968 [19 May, 1967], No. 20572/68. Heading B7N. [Also in Division H4] In a signalling arrangement for a railway system using electrically continuous rail track in which signals are applied to sections of the track for track circuit or train control purposes, band stop filters are used to prevent a signal in one section entering adjacent sections of the track.

Title: Method and apparatus for upsetting steel wires
IPC: B21J9/08
Filed: 1967-05-03
Abstract: 1,135,726. Upsetting. NIPPON CONCRETE KOGYO K.K. 3 May, 1967 [2 Dec., 1966], No. 20642/67. Heading B3H. The end of a steel wire W such as a concrete reinforcing rod, is upset at an elevated temperature which satisfies the formula where t is the heating time in sees., T is the working temperature in ‹ C., and α and # are constants dependent upon the size and composition of the wire. This may be of highmanganese high-carbon steel. The upsetting is effected by clamping the rod or wire W between a fixed jaw 3 and a movable jaw 2 actuated by a pneumatic piston 6 and fixed to copper electrodes 8, 9 connected with the upsetting head 20 in a resistance heating circuit supplied by a tapped transformer Tr. In operation, a foot switch S is actuated to energize a solenoid valve 14 which admits air above piston 6 to close the jaw 2. As pressure builds up in duct 16, a pressure switch S 1  is closed to energize timer T and also to close solenoid switch M. This energizes transformer Tr and simultaneously solenoid valve 24 admits pressure air to the right of piston 21 whereby head 20 contacts the end of the wire W to commence the heating cycle. Subsequently, timer T opens switch M to stop the heating current and upsetting continues until switch S 2  is tripped by finger 26 to reverse the piston 21. The working temperature is adjusted by the control arm 34 of transformer Tr and the heating time is adjusted manually or automatically by the timer T.

Title: Improvements in and relating to plug-in electric switches
IPC: H01R13/707
Filed: 1933-07-22
Abstract: 419,321. Plug couplings combined with switches. HAMPTON, J., The Laurels, Barr Common, near Walsall. July 22, 1933, No. 20677. [Class 38 (i).] A switch, comprising a spindle 14 with two barrels 17 carrying contacts 18 that bridge fixed contacts 11, 12, is biassed to the open position by a spring 20. This spring also presses the spindle axially forcing an oblique pin 24 on the spindle into engagement with a detent 26 cut in the wall of an earthing socket 10 so preventing the switch from being closed. The pin 24 enters the socket 10 sufficiently to be displaced by the earthing plug 10a, Fig. 5, thus unlocking the switch, which can then be opened or closed by rocking the lever 22. When the switch is closed the pin 24 enters a notch 27 in the socket 10 and by its engagement with the plug 10a retains the switch in its closed position. If the plug is withdrawn it allows the spring 20 to open the switch, this taking place before the live plugs leave their sockets. The action of opening the switch is accelerated by a spring 28 compressed by the plug 10<a> and engaged by a pin 25 on the spindle 14 when the switch is closed. The spring 28 thus acts against the spring 20 to move the spindle axially if the plug is withdrawn while the switch is closed. According to the Provisional Specification instead of the spindle moving axially to cause the pin 24 to engage the earthing socket, the pin 24 may be pivoted on the spindle and pressed by a spring towards the socket.

Title: Improvements in or relating to injection pumps for internal combustion engines
IPC: F02M59/46
Filed: 1935-07-20
Abstract: 460,196. Fuel - injection pumps. BOSCH AKT.-GES., R. July 20, 1935, No. 20684. Convention date, July 20, 1934. [Class 102 (i)] The output of a fuel-injection pump is controlled by edges on a plunger 12 co-operating with suction and byepass ports 14, 15. The pump delivery valve 8 has throttle passages 9, a piston body 18 and a tapered seat 5. At full load as the speed of the engine increases the lift of the valve increases and at the end of the delivery stroke the greater the lift the more fuel is allowed to escape from the delivery pipe to the pump chamber. Thus the maximum quantity of fuel delivered decreases as the speed increases.

Title: Exhaust gas treatment apparatus and method
Inventor: MORRIS CHARLES WILLIAM
IPC: F01N13/02
Filed: 1969-04-23
Abstract: 1,261,366. Valves. C. W. MORRIS. 23 April, 1969 [25 April, 1968], No. 20693/69. Heading F2V. [Also in Divisions F1 and G3] An apparatus for treating exhaust gases of an I.C. engine (see Division F1) includes a valve unit 38, Fig. 1, having a flap valve (185), Fig. 7 (not shown), spring-biased towards a conduit 181 but normally held by a diaphragm 192 in a position in which it closes a conduit 182. The diaphragm is normally communicated with a vacuum reservoir 207 via a pipe 194, a temperature-responsive valve 39 and a pipe 206. However, excessive temperatures sensed by probe 224 cause a spring-biased pivoted lever 213 of the valve 39 to close the associated end of the pipe 206 and open the associated end of a compressed air supply pipe 141, which causes the diaphragm to move the flap valve to a position in which it closes conduit 181 and opens conduit 182. A temperature-responsive valve 37 operates in a similar manner to the valve 39 to open or close the associated end of a single pipe 160. A valve 36, Figs. 1, and 4, selects which of two vacuum sources communicated thereto through pipes 96, 99 is to be communicated with a pipe 78. When the vacuum communicated through pipe 96 is of sufficient value, a diaphragm 84 and a connected valve member 93 move leftwards (as viewed in Fig. 4) to communicate the pipe 78 with pipe 96 and prevent communication between pipes 78 and 99. Fall in vacuum communicated through pipe 96 results in the diaphragm and valve member moving to the position shown to communicate the pipe 78 with the alternative vacuum source via pipe 99. A spring-biased check valve 104 is provided. The engine air cleaner 24 has a conical intake nozzle 115 supported for longitudinal movement along guides (117, 118), Fig. 5 (not shown), in the bowl portion of the cleaner. When air flow through the nozzle exceeds, e.g. 50 cu. feet per min., the air pressure on the forward lip of the nozzle forces the conical nozzle longitudinally further into the bowl portion to create an annular additional air opening between the nozzle and the aperture (120) through which the nozzle extends into the bowl portion. The nozzle has a number of angularly-spaced fins (119) on the outer surface thereof which co-operate with the aperture to maintain concentricity of the nozzle therewith.
