Abstract: 1434050 Power system supervisory control TOKYO DENRYOKU KK 7 Aug 1973 [7 Sept 1972] 37455/73 Heading H3H In a supervisory system for an electric power system, analogue data at various points in the system is simultaneously sampled and converted to digital signals and the digital signals are processed in data processing means. As described, the analogue data comprises voltages, currents and switch positions, the first two which vary over a short period being sampled by synchronous coders 62, 63, and 64 and the switch positions by asynchronous coders 71, 72. Each synchronous coder is controlled from timing pulse generator 60 and produces a digital output synchronized with the timing pulses after consideration of transmission delay. Each digital signal comprises a 16-bit signal comprising, a parity bit, a sign bit, 11 data bits, a range bit (indicating whether the data is all present or only the most significant bits due to an over range signal) and a bit confirming that the synchronism is operating. The data signals are time division multiplexed and fed to interconnection control unit 75, where storage checking and some calculation are performed. Further processing is performed in the high and low speed computing units 78, 79 and the memories 76, 77. Process control signals are output via interface 80 and transmission of data between power houses is via transmitter 88. Supervisory control signals may be entered at 82 and a printer or waveform recorder 83 may provide a visible indication of operating conditions.

Title: Improvements in circuit arrangements for detecting phase unbalance

IPC: H02H3/34
Filed: 1965-09-02
Abstract: 1,136,822. Protective arrangements. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 26 Aug., 1966 [2 Sept., 1965, No. 37551/65. Heading H2K. An arrangement for indicating and protecting against unbalance in a polyphase circuit, comprises for each phase 4 ... 6 of the circuit, a current transformer 7, a bridge rectifier 8 and a resistor 9, the voltages developed across the resistors 9 being smoothed and applied to respective inputs of a logic circuit 12 which provides an output signal proportional to the difference between the highest and lowest voltages when unbalance exists. This output signal is applied to an amplifying transistor Tr1, the output of which controls a bi-stable trigger circuit formed by transistors Tr 2, Tr 3 and feedback resistor R. The coil 13 of a relay is connected in the collector circuit of the transistor Tr 3, this relay operating a visible or audible alarm when the unbalance reaches a predetermined value. A further bi-stable trigger circuit is formed by transistors Tr4, Tr5 and feed back resistor R1 and is controlled by the transistor Tr1 so as to operate at a higher value of unbalance and to cause a relay 17 to effect disconnection of the protected circuit. Resetting of both bi-stable circuits is effected by the operation of a push switch 14 unless a link 2 is opened to disconnect the resistor R, in which case the transistor circuit Tr2, Tr3 restores automatically when the unbalance ceases so stopping the alarm. A diode D7 prevents false indication of unbalance due to an overall overload condition.

Abstract: <PICT:0344119/III/1> In a cyclic process for effecting catalytic gas reactions, such as the synthesis of ammonia, or of hydrocarbons or oxygenated organic compounds from hydrogen and an oxide of carbon, the reactants are brought into contact with the hot catalyst, make-up gases are then added, and the resultant mixture is brought into contact with the purifier material.  Reaction products are then removed, and the gases recirculated.  The purifier material may be in heat exchange relation with the catalyst.  The gases are admitted through an inlet F, and are heated by passing upwards between an outer wall B and the catalyst chamber A.  Thence, they pass through the main catalyst C, for instance, at 550 DEG  C., and then, mixing with make-up gases from E, pass through the purifier catalyst D to outlet G.  After removal of the products, the gases are returned to the same or similar apparatus.  In a modification, a single catalyst chamber is used, the make-up gases being introduced at the junction of a layer of purifier and main catalyst.  These may be similar in composition, for example, such as may be obtained by fusion and reduction of a mixture of iron, potassium, and aluminium oxides, for the ammonia synthesis, or a mixture of copper, chromium, and zinc oxides for the production of oxygenated organic compounds.ALSO:<PICT:0344119/IV/1> In a cyclic process for effecting catalytic gas reactions, such as the synthesis of hydrocarbons or oxygenated organic compounds from hydrogen and an oxide of carbon, the reactants are brought into contact with the hot catalyst, make-up gases are then added, and the resultant mixture is brought into contact with purifier material.

Abstract: 1486283 Vacuum cleaners HOOVER Ltd 12 Sept 1974 [13 Sept 1973] 39895/74 Heading A4F [Also in Divisions F1, F2 and H1] A floor care appliance such as the canister-type suction cleaner shown comprises an electric on/off control switch 214, Fig. 10 or 245, Fig. 19, mounted on the body 11 and which can be operated by means at a remote location, e.g. the handle 76 of wand 68, for generating a pressure wave in conduits 64, 70 linking the generating means and a fluid-pressure operated actuator which, in response to a pressure wave, urges a switch operating member in one direction, the switch 214 or 245 being switched on when the operating member is urged in the one direction in response to a pressure wave and then released, and being switched off when the operating member is urged in the one direction by a subsequent pressure wave and then released. As shown in Fig. 8 the generating means comprises a piston/cylinder device 72 operated by pressure on a manual button 113. Alternatively, as in Fig. 18, (not shown) a squeeze bulb (230) may be used. The generated pressure wave is conveyed through a conduit 64 enveloped with suction hose 66 in a common coating 134 and linked at housing coupling fitting 28 with a conduit 70 connected either to a piston/cylinder device 182, 184, Figs. 10 and 11, or a bellows 232, Fig. 19. In the arrangement shown in Figs. 10 and 11, a pressure wave in conduits 64, 70 causes a pistonrod 196 to move to the right against the bias of a spring 194 and surfaces 210, 212 of a cam plate 208 secured to the piston-rod depress a button 216 of the switch 214. Rightward movement of the piston-rod 196 also causes a camming member 204 projecting from the rod to turn a pawl 218, rotatably mounted on a housing 190, into a position in which it blocks complete leftwards return movement of the piston-rod 196 by engaging a corner 226 of a latch cam 224 mounted on the rod 196. The button 216 is held depressed until the next pressure wave urges the piston-rod to the left whereupon the member 204 turns the pawl 218 further into a position in which, upon subsequent return of the piston-rod, the latch cam 224 is not blocked. The button 216 is then released. In the arrangement shown in Fig. 19 a pressure wave expands the bellows 232 and moves rods 234, 238 to the right, the rod 238 engaging a cam 262 on a pivotally-mounted switch blade 246 in order to turn the blade and close the switch. A spring 268 provides an over-centre action. A subsequent expansion of the bellows causes the rod 238 to move rightwards again, but this time the rod engages a cam 264 on the switch blade 246 which is thereby turned to open the switch. In either arrangement the switch 214 or 235 may be operated by a manual button 74 or 74' on the cleaner body as an alternative to being remotely operated. Specifications Nos. 1486281, 1486282 and 1486015 relate to other aspects of the appliance disclosed in this Specification.

The clamping plates may be lined with leather, rubber or plastics material. When the upper has been clamped in a U-shape between the clamping plates the stretching tool 41 is raised by a pneumatic ram (not shown) to stretch the upper. The stretching tool may be heated.
