Title: Circuit Arrangements for Current Consuming Apparratus
IPC: H03K17/725
Filed: 1967-12-27
Abstract: 1,158,020. Control systems for consumption apparatus. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 27 Dec., 1967 [30 Dec., 1966], No. 58662/67. Heading H2H. A system for supplying from an A.C. source a load having a positive temperature coefficient of resistance is so arranged that the current flow in the load at starting is reduced. A load 3 such as an incandescent lamp is supplied from an A.C. source 1, 2 by way of a pair of reverse parallel connected thyristors 6, 11, the control signals for which are derived from a circuit comprising capacitors 7, 10 and resistors 8, 9, the resistor 8 having a negative temperature coefficient of resistance. When switching on the resistor 8 is cold and has a high resistance. The capacitors 7, 10 will-in consequencetake a relatively long time to charge to a value sufficient to break down the DIACS 14, 17 and supply the thyristors 6, 11 with trigger signals. The current flow in the lamp 3 will therefore be small. As the resistor 8 warms up and its resistance falls, the capacitors 7, 10 will charge more quickly. Thus the thyristors 6, 11 will fire earlier in the respective half cycles of the A.C. supply and the current flow in the lamp 3 will increase until the normal current flow is reached. If desired the resistor 9 may be a variable resistor by means of which the current flow through the lamp 3-and hence its brilliancy-may be controlled. In another embodiment the thyristors 6, 11 may be replaced by a TRIAC in which case the control circuit will comprise only one of the capacitors 7, 10.

Abstract: 1,182,848. Soldering. INTERNATIONAL BUSINESS MACHINES CORP. 10 Dec., 1968 [12 Jan., 1968], No. 58696/68. Heading B3R. [Also in Divisions C7 and H2] An electrical contact pin comprises a conductive pin base, which may be of nickel, coated with gold to a thickness of at least 75 Î 10<SP>-6</SP> inches on at least one region and to not more than 25 Î 10<SP>-6</SP> inches on at least one other region. As shown, the pin 12 passes through a series of aligned, copper-plated holes 20, 22, 24 in a composite printed circuit board 10 and is soldered to the conductive layers 14, 16, 18 along the thinly plated region of the pin. The upper limit to the gold thickness of 25 Î 10<SP>-6</SP> inches in this region results in homogeneous joints and fillets 30, 32, 34, 36, 38 without the contamination of crystalline tin-gold alloy encountered in prior art contact pins plated to a thickness of 75-150 Î 10<SP>-6</SP> inches. One of the thickly plated end portions 40, 42 may be used as a male connector whilst the other may be swaged to make it suitable for soldering or wirewrapping to other circuitry. The shoulders adjacent each end of the central region prevent the solder from wicking on to the contact surfaces 40, 42. The gold plating is applied to a uniform nickel pin in two stages. The central region of the pin is first masked with an insulating substance, conveniently a phenol-formaldehyde based printer's ink applied by part of an offset printer and then oven-cured, and the end portions 40, 42 receive a first gold coating by electrolysis. The mask of ink is then removed in a solution of hot sodium hydroxide and the pin is further plated by electrolysis over its entire surface.

Title: A roller lock for a vehicle wheel cleaning machine roller
IPC: B60S3/04
Filed: 1978-07-27
Abstract: A roller lock has a locking member 13 which extends generally parallel to the roller axis and has at one end a hardened nose 14 to engage in one of a series of recesses 15 in a flange 16 on the roller end. The locking member is mounted to pivot about a horizontal axis at right angles to the roller axis and at its end farther from the roller it has a dog 25 to be engaged by a cam 24 at the end of a short horizontal rotary shaft 21 parallel to the roller on which shaft is mounted the lower end of a lock-operating handle 20 that swings to and fro in a plane at right angles to the roller axis between two oppositely inclined rest positions. When the handle is in one rest position, a spring 18 pulls the locking member into engagement to lock the roller, the cam being at this time out of contact with the dog on the locking member. Swinging of the handle over into the other rest position causes the cam to bear on the dog to force the locking member out of engagement with the roller flange.   <IMAGE>

Title: Isotopically selective condensation of gases
IPC: B01D59/50
Filed: 1978-07-31
Abstract: Supersonic flow of a molecular gas under the appropriate conditions through an expansion nozzle, produces homogenous condensation of the gas. if the gas is vibrationally excited, the condensation is inhibited. Thus, selective vibrational excitation of an isotopic species in the gas provides a means of controlling the condensation of the gas. Such selective vibrational excitation may be readily accomplished by means of laser irradiation of the supersonically flowing gas. The controlled condensation in turn may be used as the basis of isotope separation and enrichment by subjecting the stream of gas and condensate particles to aerodynamic processes whereby the condensate particles are separated from the main flow of the gas.
