Filed: 1970-12-01
Abstract: 1338248 Welding by pressure TRW Inc 1 Dec 1970 [1 Dec 1969] 57137/70 Heading B3R In a method of resistance welding an element to a metal support a vacuum is established around the weld area to load the element against the support. A metal-plated trim member 1 having weld studs 12 to be welded to a metal panel 23 e.g. of a motor vehicle body, is supported in a suitably shaped recess of an electrode 22, 29 provided with an insulating backing member 28. A flexible urethane rubber skirt 31 extends from the edge 28a of the backing member and is adapted to make sealing contact with the panel 23 to provide an enclosure which may be evacuated through a bore 33 in the fitting 32. The vacuum created urges the studs 12 against the panel sufficiently to penetrate any paint coating and upon reaching a predetermined degree of evacuation a vacuum switch is operated to apply welding current. The current flows to the welding studs 12 via the plating on the trim member 1. After cooling air is admitted to the enclosure to release the load and allow removal of the welding device.

Abstract: 1298332 Control of stepping motors UNITED KINGDOM ATOMIC ENERGY AUTHORITY 4 Dec 1969 [5 Dec 1969] 57923/68 Heading H2J In a stepping motor having an odd number of star-connected field windings, the windings are energized at all times and an effective rotating field is produced by connecting the free ends of the windings in a predetermined order to two alternative voltage levels through switching circuits controlled by the outputs of a ring counter comprising as many bi-stable elements as there are field windings in the motor. The motor shown has five field windings A-E and a 2-pole permanent magnet rotor to provide ten steps per revolution, the windings being energized from either a + 14 volt line or a - 14 volt line through transistor switching circuits, Fig. 4 (not shown).

Title: Electrical power distribution system
IPC: H02H3/30
Filed: 1971-12-16
Abstract: 1355827 Protective arrangements MERLIN GERIN 16 Dec 1971 [17 Dec 1970 20 Sept 1971] 58479/71 Heading H2K A distribution system comprising a first junction 144 interconnecting at least one incoming conductor 12 with a plurality of outgoing conductors 14... 18 which form incoming conductors to further junctions 145 ... 149 with outgoing conductors 20 ... 34, is protected by a single means 68 ... 86 for detecting the current in each conductor, a circuit-breaker 36 ... 42 in each incoming conductor, instantaneous tripping means 60... 66 for each of these circuit-breakers, and a control circuit interconnecting the detectors at each junction with the associated tripping means in such a manner that the signals detected from the currents at the respective junctions normally sum to zero. In the arrangement shown, the detecting means are current transformers with their secondary windings connected in a control circuit which is substantially a replica of the protected system. Should a fault occur at E on conductor 32, the fault current flows through transformers 68, 74, 84 in series so that the currents in the control circuit still sum to zero and neither circuit-breaker 36 or 42 is tripped, the fault being cleared by the tripping of a circuitbreaker 56 by its conventional thermal-electromagnetic tripping device 116. Should the fault not be cleared, the current flowing in the control circuit causes a fuse 100 to blow, the resulting shunting of the current through the tripping means 66 trips the circuit-breaker 42. If a fault occurs at D, the tripping means 64 is energized to trip the circuit-breaker 40, but should the circuit-breaker not clear the fault, then a fuse 94 blows to cause the tripping means 60 to be energized to trip the circuit-breaker 36. This circuit-breaker has conventional tripping means 126 which are operative should the control circuit fail. In a modification, Fig. 2 (not shown), the current detectors are Hall-effect elements, the control circuit being arranged so that the voltages produced by the elements associated with each junction normally sum to zero. Reference is also made to the use of detectors, each comprising a torus with a large air gap and a secondary winding connected to a high impedance so that the signal produced is proportional to the rate of change of the current.

Patent GB-2030721-A (GB)
Title: Colorimeter
IPC: G01J3/52
Filed: 1978-07-11
Abstract: In a portable colorimeter for the measurement of surface colour to determine the characteristics of any given colour according to the CIE system and the SINOID system, the colour to be measured is optically contrasted with a colour obtained by additive mixing from standard etalons with standard black and standard white until a colour identical with the colour to be measured is produced. The phenomenon that the components of different primary or secondary light standards can be intermixed by using a surface that reflects all light diffusely is employed. The surface to be measured and the measuring surface, which latter is symmetrically variable with respect to the proportions of colour components but which is of constant overall size are illuminated by a common light source. The resulting colour, which can be varied by varying the relative areas of the standard components is mixed by being reflected from the measuring face to the observer by means of a diffusely reflecting mirror. <IMAGE>

Title: Duplicator stencils
IPC: B41C1/14
Filed: 1978-07-25
Abstract: The invention consists in generating the holes in a duplicator stencil by activating a potentially reactive material formed to the shape of a required image on an uncut stencil by an electrophotographic process. Formation of the image is effected by photoconductive discharge of an electrically charged surface to produce an electrostatic image and development of the image by electrical attraction of fine particles of toner. Examples are described wherein a dispersion of fine particles is dispersed onto Yoshino tissue to form an electroconductive support. This is over-coated with a spectrally sensitised dispersion containing a photoconductive material such as zinc oxide to form a photoconductive layer. After drying and dark adapting the coatings are imaged by an electrostatic copier and the electrostatic image developed with a dry toner powder containing iron oxide, a resin, and a blowing agent. The developed sheet is heated to produce a stencil by the exothermic decomposition of the blowing, agent, the ink-impervious stencil material being softened and the holes blown by evolved gas.

Title: Improvements in or relating to switching mechanisms
IPC: F16K21/18
Filed: 1978-08-23
Abstract: Devices which are known for operating valves in dependence on the level of a fluid in a container include conventional water cisterns which, by virtue of the valve being partially open for a considerable time, lead to a slow and noisy make up of water in the cistern. The invention provides a device for controlling the position of an interface 14 between first 12 and second 13 immiscible fluids in a container, the first fluid being denser than the second. The device comprises a fluid control switch 3 which operates from first to second states in dependence on the fluid level, and, operably connected thereto, a fluid level sensor comprising a first, positively buoyant, element 9 and a connected second, non-positively buoyant, element 11. The response of the sensor to the fluid level causes the switch to trip and (i) permit or prevent make up of the container, or (ii) permit or prevent batch delivery of fluid from the container. <IMAGE>

The collars are then removed and the welded-together sections are displaced axially in readiness for welding the next section in place. This technique enables simple and easily- operated apparatus to be used. The weld itself is of enhanced quality; and the rate of welding is improved. <IMAGE>
