Abstract: 1401520 Pivoted armature transducers BELL NORTHERN RESEARCH Ltd 28 Dec 1972 [12 Jan 1972] 59793/72 Heading H4J In a pivoted armature transducer such as described in Specification 1,379,372 the central portion of a peripherally fixed diaphragm 12 (Fig. 2) is linked to an armature 20 by a flexible linkage bar 100 having a reinforcing formation 102 (see also Figs. 3A, 3B, 3C) along its central portion to provide a relatively rigid central portion and flexible end portions. One flexible end portion is spot welded to an armature extension 23 normal to the armature 20. The other flexible end portion is attached, e.g. by epoxy adhesive 15, to the centre of the diaphragm 12. Longitudinal motion along the flexible linkage bar 100 is coupled between the diaphragm 12 and the armature 20. Associated lateral movement induced by pivoting action of the armature 20 is substantially absorbed by the flexible end portions of the linkage bar 100. The flexible end portions assist in providing a relatively linear frequency response, e.g. in the range 2800 Hz to 3300 Hz. The linkage bar 100 is formed from copper beryllium alloy sheet stock. The armature 20 is a one-piece structure formed from sheet stock having a high magnetic permeability and comprises a body portion 21 (see Fig. 3B) having two broad end portions tapering to a narrower central portion. A lightening hole 26 is provided. A narrow projection in the plane of the armature. carries the armature extension 23. A pair of torsion bars 22 extend laterally to a pair of support arms 24 (Fig. 3C) extending about the length of the body portion 21. The support arms 24 have U-shaped brass spacers 25. The brass spacers 25 enclose the arms 24 and are clamped between pole faces 72, 74 of U-shaped portions of a pair of magnetic polepieces 71, 73 (see Fig. 2). The brass spacers 25 define the size of the air gaps between the pole faces 72, 74 and the ends of the armature body 21 to permit pivoting of the armature body 21 upon the torsion bars 22. The polepieces 71, 73 are fed from a cylindrical permanent magnet 75.

Abstract: 1294770 Soldering HITACHI Ltd 22 Dec 1970 [29 Dec 1969] 60892/70 Heading B3R [Also in Division H1] In connecting a wire to a metal layer on a substrate the wire is guided through the passage of a capillary tube and a portion of the wire extending from the tube is pressed against the layer by the tube, the tube is heated to a temperature not lower than the melting point of the layer but lower than the melting point of the wire whereby the portion of the wire is pressed into the metal layer while metal of the layer is melted and the layer is then cooled to bond the wire to the layer, the tool being then moved away. An electrode 2, Fig. la, printed on a ceramic substrate 1 of a semi-conductor device carries a lead-tin solder layer 3 and a silver wire 5 is guided through the passage of a capillary tube 4. A head 6 is formed on the wire by burning in a hydrogen flame. The tube 4 is heated by resistance means to a temperature not lower than the melting point of the solder 3, e.g. to 300 C. and the substrate 1 may be heated say to 100 C., the tube 4 is lowered to press the head 6 against the solder and heat conducted to the head 6 from the tube melts the solder in contact therewith and the head becomes buried in the solder. A gas is then directed from a jet on to the melted solder to solidify the solder and then the tool is moved upward over the wire. The wire may be connected to a solder layer forming an electrode on a semi-conductor substrate or on a junction type transistor. The tool after being moved upwardly over the wire may be then moved towards another part of the layer 3 without cutting the wire so that a hook shaped part 9, Fig. 2a, is similarly fixed in the solder layer and cooled by gas from nozzle 7. The upright portion of the wire is then burned through by a hydrogen flame to form a balled ends on the wire.

Abstract: 1372433 Thermal regenerators R N PENNY 21 Dec 1972 [31 Dec 1971] 60894/71 Heeding F4K [Also in Division FI] In a thermal regenerator having a disctype matrix 3 mounted for rotation within a housing 1, 2, the matrix is surrounded by an annular bearing ring formed by interengaging arcuate blocks 16, 17 of two different materials, e.g. a metal and a ceramic, the blocks being supported from housing liners 14, 15 by couplings 18 which permit limited radial and circumferential movement of the blocks relative to the liners 14, 15. Hollow walls 4 and 5 carrying bar-like seals 10, 11 separate the heat exchange fluids (e.g. compressed air and turbine exhaust gases) upstream and downstream of the matrix. Compressed air from passage 6 enters wall 4 via a port 23 and from there flows via a passage 19 behind the seal 10 and grooves (31, 32, Fig. 4) to an annular passage 25 surrounding the bearing ring. The ring is formed with nozzles 26 which direct the air into sawtooth-shaped depressions 27 formed in the rim 13 of the matrix and so effect rotation of the matrix. Spent air leaves through a bleed duct 28 and passes via the passage 20 behind the bar seal 11 to the wall 5 from which it rejoins the heated air stream in chamber 8 via a port 24. In alternative embodiments the arcuate blocks 16, 17 may be replaced by pairs of bearing blocks (33, 34, Figs. 5 and 6, not shown) arranged side-by-side and end-to-end between the annu-  lar liners 14 and 15. The matrix can be rotated by means of a drive shaft on which it is mounted.

Filed: 1968-12-30
Abstract: 1,201,584. Control of A.C. motors; core constructions. LICENTIA PATENT-VERWALTUNGS-G.m.b.H. 30 Dec., 1968 [30 Dec., 1967], No. 61606/68. Headings H2A and H2J. A synchronous motor has an unwound rotor with salient poles, and its stator is supplied from an inverter which receives commutating signals to determine the speed of the motor. The rotor is coupled to a position transducer which detects the load angle of the motor, and which develops signals for controlling the inverter. When the motor tends to hunt or fall out of synchronism due to overload, the signals from the transducer are temporarily delayed to prevent the optimum load angle from being exceeded, the motor being restored to its normal speed after the overload is removed. The rotor and stator are both laminated, and the rotor is slotted in the manner of reluctance motors. The gaps between the rotor poles are filled in to prevent air turbulence. The stator voltage is normally constant, and is reduced only after the frequency has dropped by a substantial amount. Regenerated energy is controlled by a resistor connected to an electronic switch. The inverter has a buffer capacitor and is supplied by a rectifier.

IPC: B60G15/00
Abstract: 780,612. Spring suspensions; preventing lateral canting; hydraulic shock absorbers. WOODHEAD-MONROE, Ltd. Feb. 15, 1956 [Feb. 16, 1955], No. 4666/55. Classes 108(2) and 108(3) Relates to a vehicle suspension system wherein two hydraulic telescopic shockabsorbing devices applied at opposite sides of a vehicle between sprung and unsprung parts thereof are connected to a common control unit. According to the invention, in such a suspension, the control unit comprises two separate chambers to each of which one of the shock absorbers is connected, so that liquid may flow from each shock absorber to its respective chamber and vice-versa a displaceable element in each of the chambers movable as a result of the displacement of the liquid into or from the chamber, and means whereby a selected fluid pressure loading will be applied simultaneously to both elements to counteract or retard displacement of the liquid from the respective shock absorber, the arrangement being such that on compression of both shock absorbers displacement of both elements takes place against the pressure loading, while compression of one only of the shock absorbers is prevented or retarded by the appropriate element while the other element is effective to prevent or retard extension of the other shock absorber. As shown, in which a rear axle 10 is suspended at each end from a cross frame member 15 by a hydraulic shock absorber of either of the forms 11 and 12 shown or of any other suitable type, each shock absorber communicates through a pipe 17 with the underside of a diaphragm 23 or 24 in a control unit 18 mounted on the member 15. The diaphragms 23 and 24 are located in separate compartments 21 and 22 respectively defined by a rigid partition 20 through which the diaphragms are connected together by a bolt 25. The upper side of each diaphragm is subject to compressed air controlled by valves 28 and 30 respectively which may be pre-set or which may be operated from within the vehicle. The axle 10 is also connected to the frame by longitudinal links Fig. 2 (not shown). In operation, variations in load at one or both ends of the axle deflects both diaphragms 23 and 24 against the compressed air in the unit 18, while suspension movements of the axle are controlled by the shock absorbers 11 and 12. In a modification, Fig. 3 (not shown), the control unit comprises a pair of pistons resiliently coupled together by a rod extending through a partition wall of the casing of the unit. As in the previous arrangement, the shock absorbers communicate with the under sides of the pistons the upper side of which are subject to compressed air. In a further modification, Fig. 4 (not shown), the control unit comprises a casing provided with a pair of pistons slidable in adjacent cylinders, the lower ends of which communicate with the shock absorbers and the under sides of the pistons. The upper sides of the pistons are engaged by a member common to both pistons and slidable against compressed air acting on a diaphragm bearing on the member.
