Title: Improvements in or relating to tools for making wrapped electrical connections
Inventor: SILINS ALEKSANDRS
IPC: H01R43/033
Filed: 1968-04-30
Abstract: 1,237,399. Wire-wrapping tool. GENERAL ELECTRIC CO. Ltd. 30 April, 1969 [30 April, 1968], No. 20372/68. Heading B3E. A tool for making wrapped electrical connections using insulated wire comprises a bit 1 having insulating severing means 21 and which is rotatable relative to a sleeve 2, the bit being adapted to embrace a terminal and on rotation about the terminal to wrap a wire around it. In operation the bit 1 and sleeve 2 are aligned so that the insulated wire can be freely passed from the leading edge 13 of the tool, over the blade 21, into a groove 14 and through a shearing hole 41. The other end of the wire is left sufficiently long to reach between the two terminals that are required to be connected and to wrap one of them. The hole 12 in the bit is then placed over the terminal and the free end of the wire is anchored by passing it through a notch 37. The bit 1 is rotated in a clockwise direction as viewed by the operator causing shearing of the surplus wire protruding from the shearing hole 41. At the same time the insulated wire lying in groove 45 and thus in the gap in a ring cutter 44, Fig. 11, is thrust by the wall of groove 16 out of the sleeve groove 45 and into the space between the ring cutter 44 and the blade 21 thus severing the insulation. Rotation of the bit 1 against the tension in the anchored wire drags the wire along the groove 14. The ring cutter 44 and the blade 21 block the passage of the severed insulation so that as the bit 1 is rotated, first the insulated wire and then the bare wire are wrapped around the terminal. As the trailing end of the wire rounds the bend into a V-shaped area 23 a countersunk surface 28 presses the end against the terminal. The tool is removed and the previously anchored end of the wire is inserted into the leading end of the tool. The tool is then applied, tied as it is to the first terminal, to the second terminal and the operation repeated.

Title: Remote control system for a press or the like
IPC: B30B15/14
Filed: 1964-05-19
Abstract: 1,026,727. Transistor switching circuits. DANLY MACHINE SPECIALTIES Inc. May 19, 1964 [May 31, 1963], No. 20659/64. Heading H3T. [Also in Division G1] A relay coil CR20 is arranged so that it is not actuated when a control voltage from a bridge B20 is below a first value, is actuated while the voltage is between the first value and a second value, and is again unactuated when the voltage rises above the second value. As the voltage from bridge B20 is swept from a negative to a positive value a point is reached where transistor TR20 conducts and triggers a silicon controlled rectifier SCR20 in series with relay coil CR20. At a second, higher, voltage transistor TR21 becomes conductive, short-circuiting the base-emitter circuit of TR20 to remove the triggering voltage from SCR20. Resistor R23 may be adjusted to vary the voltage at which TR21 conducts. Thermistors TH20, TH21 and TH22, and further temperature-responsive element SE20 provide temperature compensation.

IPC: H05B3/16
Filed: 1960-06-13
Abstract: 904,317. Determining physical dimensions. BRITISH INSULATED CALLENDER'S CABLES Ltd. June 13, 1961, [June 13, 1960], No. 20685/60. Class 37. In a method of, or an apparatus for, detecting variations in the length of lay of an electric conductor, e.g. a resistance wire or strip, applied helically to an insulating support, the core C, Fig. 1 is drawn over pulleys 1 through a coil 8, fed from H.F. oscillator 10, so as to induce a voltage in the conductor located between the pulleys for supplying an indicating, recording and/or control circuit. The indicating &c. circuit comprises a coaxial cable 12 matched with an input transformer 13 which supplies by way of a tuned amplifier 15 and rectifiers 18, 19, trigger circuits 21, 22 which respond respectively to positive and negative outputs. When due to " bunching " of the helical conductor the positive output rises above a pre. determined value the indicating lamp 24 is operated and a relay 27 may be operated to switch off the winding motor M for the core. Similarly if due to spreading of the conductor, or breakage thereof, the negative output falls below a predetermined value the lamp 25 and relay 28 are operated. Prior to testing a length of core the apparatus is calibrated by using a sample length having the turns of a conductor of known resistance spaced at correct intervals. After operation, the trigger circuits may be reset automatically or manually. In a modified form of apparatus (Fig. 2, not shown) the coil 8 is connected into a bridge circuit with a second identical coil which embraces a standard length of core having the turns of the conductor spaced at the correct intervals. In a further modification, the trigger circuit 22, Fig. 1, may be dispensed with. Preferably the coil 8 has an axial length which is less than the length of one lay of the conductor, but may be greater although, preferably, not more than about twice the length of the lay. The pulleys 1 are of metal, e.g. copper, and are V-grooved to accommodate the core which in passing over each pulley makes contact therewith over an angle of at least about 45 degrees. Circuit contact with the pulleys is established over silver composition brushes 7 and silver slip-rings 6.

Abstract: 1505163 Thermistors FABRICA KALIANA MAGNETI MARELLI SpA 16 May 1975 [17 May 1974] 20779/75 Heading H1K A thermistor is made by crossing, in a reaction zone, conductors A, B which intersect but do not touch, introducing in a gaseous state, a compound of semiconductor material and dopants or materials which promote pyrolysis of the compound, heating the conductors A, B to the pyrolytic temperature of the semiconductor material to deposit it at the intersection only owing to the combined heating effect of the two conductors, growing the deposit until a core K is formed which electrically and mechanically connects the conductors A, B, and removing two branches of the conductors from the core to leave two other branches to act as leads. The conductors may be heated electrically and the heating may be localized by non-uniformities in the conductor cross-section or by use of insulation around parts of the conductors. A first layer of semiconductor K1 may be grown on one conductor B before the two conductors are joined by the core. Batches of thermistors may be produced simultaneously by starting with two crossed sets of conductors. The semi-conductor may be C-doped B and the conductors Mo or W.
