Abstract: 1,095,451. Circuit assemblies. JOSEPH LUCAS (INDUSTRIES) Ltd. April 9, 1965 [April 28, 1964], No. 17502/64. Heading H1R. [Also in Divisions G3, H2 and H3] In an alternator, particularly for use in road vehicles, the brushes are mounted on an insulating member 51 which is formed with recesses to locate components of an electronic voltage regulator contained within the alternator. As shown, the voltage regulator comprises a printed circuit board 47 carrying a power transistor 29, in series with the field winding, mounted on a heat sink 48, part 52 of which forms a catch used to retain the insulating member 51 adjacent the circuit board 47 with some of the components housed in recesses in member 51. Alternatively the components may be positioned in respective recesses in member 51 connections being made by strips which clip into passages moulded into the member. The assembly shown in Fig. 3 is mounted within an end cap of the three-phase alternator (Fig. 2, not shown) with the brushes parallel to the axis. Six rectifiers for battery charging and a further three rectifiers feeding the voltage regulator are also located within the end cap.

Abstract: 1,226,716. Making anodes; extruding; jointing by shrinking. BRITISH LEAD MILLS Ltd. 30 July, 1969, No. 38137/69. Headings B3A, B3P and B3V. [Also in Divisions C6- C7] A metal or metal alloy core 16 is sheathed in lead or lead antimony alloy 11 by mounting the core on a supporting rod 10 fixed in the extrusion box 12 and extruding the lead while hot through a die 15 by relative movement of the box 12 and a plunger 14. The lead is poured into the box and compressed by raising the box towards the stationary plunger 14 with the die closed by a plate 13. The core 16 is aluminium and is screwed to the supporting rod 10. After the lead solidifies it is extruded at 200-220‹ C. over the core by raising the box further, the composite product is cooled by water jets 19 causing the sheath to shrink on to the cool core. The core may be tubular and have annular keying grooves. The composite product may be an electroplating anode and have longitudinal corrugations to increase its surface area, Fig. 4 (not shown). A pair of extruded composite anodes may be screwed together and screwed on to a hanger (30), Figs. 5-7 (not shown), which supports the anode on a bus-bar.

Abstract: 1,233,853. Connections for printed circuit cards. SOC. INDUSTRIELLE BULL-GENERAL ELECTRIC. 24 Sept., 1969 [1 Oct., 1968], No. 47089/69. Heading H2E. Printed circuit cards CA1, CA2 are supported on a printed circuit panel 11 providing connections between them, the panel supporting connectors A, B, C, between pairs of which the cards are inserted. Electrical connections between the cards and the panel are provided by rows of contact blades 40, 41, whose lower ends are soldered to the panel 11, and whose upper ends have cross-members (44, Fig. 2) held in a slot in the connector body. Portion of each contact blade is thrust against a contact surface on a card by means of a push member 23 provided with two bosses 24, 25, the push members being urged outwardly by flexible blades 30, 31 which are formed in one piece with metal strip 29 supported by the connector. Strips 28 may be provided to position the push members during assembly. By varying the spacing X between adjacent connectors, cards of various widths may be accommodated, the contact blades on either side of a card may be staggered, as shown in Fig. 2, but the connectors may be fixed on the panel such that other arrangements are obtained. In an alternative embodiment (Fig. 4), the contact springs are supported by the connector at the base adjacent the panel 11, so that the flexible blades are inverted compared with Fig. 1. The contact blades are formed by gluing or depositing conductive metal strips (76, Fig. 4) on to the face of a thin insulating support sheet (77) which is fitted around the body of each connector, and held in position by plate (78) and pin (79), which are fitted to the top of the connector. The shortness of the electrical path between the cards and the panel minimizes impedance matching problems, and in a modification of the alternative embodiment of Fig. 4, the insulating support sheet has an earthed conductive layer (92, Fig. 7) on its inner surface, so that by selection of dielectric constant and thickness of the support sheet, and the dimensions of the contact blades, the characteristic impedance of the contact blades may be matched to that of the panel and the cards.

Abstract: 1,234,258. Rolling mills. SCHLOEMANN A.G. 30 Aug., 1968 [6 Sept., 1967], No. 41463/68. Heading B3M. The width of a metal strip being rolled is controlled by continuously adjusting a vertical edging stand, located at the beginning of a roll train, in order to compensate for a progressive increase of the strip width as it falls in temperature. An edging roll 22, Fig. 1, of the edging stand is laterally adjusted by a spindle 9. Movement of the spindle is effected in a housing assembly 1, the spindle being rotatable for coarse adjustment of the roll, and axially movable for fine adjustment. To provide a wide range of adjustment, the housing assembly 1 is itself movable by means of a second spindle 10 which is axially restrained by an abutment 31. For fine adjustment of the roll, fluid-pressure operated nuts 3 and 4, Fig. 2, are associated with the spindles 9 and 10. The nuts are non- rotatable and are moved axially by selectively introducing fluid into annular spaces at the ends of the nuts. The spaces accommodate rings 11 which bear against the walls of the assembly 1. Adjustment of the roll is conveniently made according to a programme produced by trial rolling.

Abstract: 1,251,614. Pressure transducers. UNITED AIRCRAFT CORP. Feb. 13, 1970 [March 12, 1969], No. 6970/70. Heading G1N. A fluid pressure transducer comprises a bellows or diaphragm subjected to the test pressure to produce a displacement which is sensed by magneto-resistive elements producing a corresponding current which is fed to a restoring coil using the same permanent magnet as the displacement sensing elements. As shown Fig. 1, a bellows 14 is attached at its lower end to the non-magnetic base-plate 12 of a magnetic structure 10, and its upper end carries a non- magnetic plate 18 on which are located magnetoresistive sensors 26-28 and a coil winding 20. The structure 10 is a permanent magnet loop of C cross-section, with its opposite poles across the gap of the C. The coil 20 is located in this gap. Pairs of flux-concentrating members 38-41 are associated with each sensor 26-28, which comprises two semi-conductor elements 32, 34 Fig. 3 on a ceramic substrate 30, to produce a flux concentration area 36 initially overlapping the elements 32, 34 symmetrically. When the test pressure is fed to bellows 14 via inlet 16, the bellows expands, the elements 32, 34 are displaced from their balanced positions so that their resistances vary differentially, the change being sensed in a bridge circuit to produce a proportional current which is fed to coil 20 and restores the assembly to substantially the same position, the current being a measure of the test pressure. In a modification the bellows is replaced by a diaphragm. In another embodiment Fig. 7, (not shown) the bellows is attached to the sensing members and restoring coil by a hinged arm, to provide mechanical advantage.
