Title: Improvements in and relating to automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1927-02-26
Abstract: 266,748. British Thomson-Houston Co., Ltd., (Assignees of Anderson, A. E.). Feb. 26, 1926, [Convention date]. Cut-out arrangements.-In an automatically. reclosing circuit-breaker system in which the supply is reconnected when the load falls off, or two load circuits reconnected to one another when the fault on one of them is cleared, a small current is intermittently supplied from the supply 1 to the overloaded or faulty load circuit 2 through an impedance 7. On fault &c. the overload relay 5 breaks the circuit of the reclosing and maintaining winding 4 of the circuitbreaker 3 and a make-and-break relay 8 is brought into continuous intermittent action by the time-controlled relays 9, 10 to connect the impedance 7 intermittently between the circuits 1, 2. Relay 10, in closing, energizes the closing coil 11 of relay 8 and also that of the timecontrolled relay 12 which if energized long enough would close the circuit of the reclosing coil 4; it is not, however, so energized while a fault remains on the line. In the example shown, in which two load circuits are to be reconnected to one another, two reclosing relays 13, 14 of the balanced differential type are employed one to effect the reclosure for fault on circuit 1 and the other for circuit 2, in con. junction with a control relay 19 which is energized when relay 8 is closed. The relays 13, 14 have restraining windings 15, 16 in series with one another and connected between the two circuits when circuit-breaker 3 is open and in shunt with the impedance 7 when the intermittent relay 8 is closed. Operating winding 17 is connected between line 1 and ground and relay 18 between line 2 and ground, both through relay 19. While the fault exists, the restraining current through the differential relays 13, 14 is adequate to hold them open, but when the fault clears the holding current, which is a measure of that through 7, falls off and one or other (or both) of the relays 13, 14 operates to close. This closure completes a holding circuit for relay 10 which supplies relay 12 for a time long enough for it to operate and to energize the reclosing coil 4. A modification in which one reclosing relay only is employed is described.

Title: Improvements in or relating to electron discharge tube amplifying, repeating and modulating circuit arrangements
IPC: H03C1/26
Filed: 1946-02-21
Abstract: 614,421. Valve amplifying and modulating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and RICH, C. W. Feb. 21, 1946, No. 5503. [Classes 40 (v) and 40 (vi)] In a valve amplifier or modulator, linearity of response is obtained by applying the input to a network in the cathode leg and applying to another electrode a voltage derived from another point in the network and dependent on departures from linearity. In the modulator shown in the drawing, carrier is applied from valve 27 to the control grid of the valve 5, and modulating voltage is applied through a transformer 2 to the cathode, the valve operating under Class C conditions. A tapping 10 on a resistance shunted across the secondary coil 3 is connected through the primary coil of a transformer 12 and a D.C. blocking condenser 13 to the cathode. The cathode lead includes a resistance 6, and so long as the cathode current changesare proportional to the modulating voltage, no current passes through the transformer 12. When the response is not linear, the secondary coil 15 applies a compensating voltage to the grid of an amplifier 17, the output of which is fed through a condenser 23 and carrier choke 24 to the grid of the valve 5. The cathode of valve 2 and the anode of valve 17 are earthed for 'carrier frequency by condensers 30, 31. A condenser 7. across the cathode resistor 6 provides phase correction. When the invention is applied to an amplifier, the carrier input and the valve 27 are omitted.

Title: Improvements in or relating to injection moulding machines
IPC: B29C45/03
Filed: 1962-02-15
Abstract: 995,749. Injection moulding shoes. BRITISH UNITED SHOE MACHINERY CO. Ltd. Feb. 15, 1962 [Feb. 16, 1961], No. 5756/62. Heading B5A. [Also in Division E2] The invention relates to a machine for the injection moulding of soles to uppers, of the type in which a plurality of mould assemblies are presented in turn to the injection mechanism. Each mould assembly 20 comprises a base 96 on which are mounted a sole mould member 120 and two side mould members 150, 152, and a cover 98 on which is mounted a foot form 188. The cover is mounted on the base for pivotal movement from a fully open to an intermediate position and then for linear movement perpendicular to the base from this intermediate position to a fully closed position in which the foot form is located against the mould members to provide the mould cavity. The mould cover 98 is pivoted to the base 96 by a shaft 106, which passes through elongated holes 108 in the cover to facilitate the linear movement. The mould parts 150, 152 are held apart when the mould is open by springs 180 and they are forced together by levers 158, 160, pivoted at 164 and having rollers 166 which press against the mould parts 150, 152. The mould is closed by pivoting it by hand to the intermediate position where it is latched in position by a latching member 206, and then by forcing it, by means of a pressure platen 198 to the fully closed position where it is locked by latch members 222, 242. The platen 198 is suspended from a beam 342 which is pivoted at 344 and actuated by an hydraulic cylinder 334 (Fig. 4, not shown). The latch member 206 has notches 208 which engage a shaft 210 carried by the cover 98. When forced into fully closed position the shaft 210 is held down by a latching surface 234 of a plate 238. The plate 238 together with plates 240, between which it is adjustably mounted, constitutes the latch member 222. The latch members 242 at the other end of the mould are somewhat similar in construction. The mould assemblies 20 are mounted on carriages 22, which are pivotally attached to links 33 of a chain 24 and have rollers 34 which run on a three part rail 36, 40, 46.

Title: Multipurpose logical matrix
IPC: G06K9/64
Filed: 1966-02-10
Abstract: 1,070,879. Pattern recognition. SPERRY RAND CORPORATION. Feb. 10, 1966 [March 12, 1965], No. 5795/66. Heading G4R. A multipurpose logical matrix for performing functions such as circular shift, pattern location, coincidence detection and permutation, comprises AND elements the outputs of which are ORed in groups and which are fed from data channels and control channels, transfer means from the latter being selectively operable to logically combine or merely distribute the control signals en route. Use in pattern recognition is mentioned. Referring to Fig. 1 (not shown), a control bit (C) in a control register (1-14) routes eight other control bits (S 0  to S 7 ) from the control register to an A-translator (1-16) or a B- translator (1-18) depending on the function required. Sixty-four output lines from the A-translator are ORed with respective ones of 64 output lines from the B-translator, to provide 64 control bit inputs to 8 decision elements (1-11), eight inputs per decision element. Eight data bits (Y 0  to Y 7 ) in an input register (1-10) are all passed to each decision element, where each is ANDed with a corresponding one of the control inputs, the results being ORed to produce a bit output from the decision element which is placed in a corresponding bit position of an output register (X 0  to X 7 ). The decision elements may each utilize electronic logic blocks (Fig. 3, not shown) or diodes and a multi-primary transformer (Fig. 2, not shown). The B-translator is used for permuting any two of the input bits, the corresponding two control bits (So to S 7 ) being " one " to achieve this. In the B-translator (Fig. 6, not shown), the control bits (So to S 7 ) are inverted and also (separately) ANDed in pairs, the inverters each providing one control input to the decision elements and the AND gates each providing two. The A- translator (Fig. 5, not shown) simply routes each control bit (So to S 7 ) to a different control input of each decision element and is used for circular shift, pattern location and coincidence detection. For circular shift, only one of the control bits is " one," depending on the number of places of (end-around) shift required. For pattern location, the pattern of " ones " and " don't cares " to be located is placed at the lower end of the control register, and the data bits (Y 0  to Y 7 ) are present in inverted form, a " zero " bit being produced in the output register for each occurrence of the looked-for pattern, the position of the " zero " indicating the position of the pattern. For coincidence detection, which is a comparison of a (control) word (So to S 7 ) with all shifted forms of the data word ((Y 0  to Y,), the data and control words are applied in true and inverted form respectively, then applied in inverted and true form respectively. Any stage of the output register still holding " zero " indicates there is coincidence and, by its position, the number of shifts required to obtain it. Coincidence detection could be done in one operation by duplicating the decision elements.

Title: Improved method of and means for temporarily protecting the surfaces of plastic and other structures
Filed: 1944-03-29
Abstract: Plastic surfaces are temporarily protected by applying an aqueous emulsion of polyvinyl alcohol of low surface tension and drying to leave a thin uniform film of polyvinyl alcohol which is peeled from the surface when protection is no longer required. Preferably, the aqueous emulsion also contains a wetting agent and a plasticizer, and, if it is desired to harden the resulting film, may also contain formaldehyde, chromium compounds, dibasic acids, copper-ammonium or zinc-ammonium compounds.  The emulsion may be applied by dipping, brushing or spraying and the film removed by use of an embedded rip cord, or an attached tab or by moistening of a corner.  The method is particularly useful for the temporary protection during manufacture of the polymethyl methacrylate panels used in aircraft.  A specified aqueous emulsion contains polyvinyl alcohol, alcohol, glycerine and a wetting agent (the dioctyl ester of sodium sulphosuccinic acid).  The emulsion may also be coloured by the addition of a dye, e.g. methyl orange.
