IPC: H01L23/42
Filed: 1958-08-14
Abstract: 891,934. Transistors. STANDARD TELEPHONES & CABLES Ltd. Aug. 7, 1959 [Aug. 14, 1958], No. 26120/58. Class 37. In a junction transistor, one of three lead wires, which pass through an electrically insulating member and are connected in low resistance contact to the electrodes of the transistor, has a cross-sectional area substantially greater than that of the other two lead wires, and a heat conductive container enclosing the device is in thermal contact with said member. As shown, Figs. 8 and 9, a transistor comprises a crystal element 61 of e.g. Ge, having alloyed emitter and collector electrodes 64, 65, of e.g. In, and an ohmic base electrode 63 comprising a metal ring and a free extending portion. The electrodes are connected to lead wires 2, 3, 4 which may be of a Cu-coated Ni-Fe alloy or Cu, plated with e.g. Au, and which are sealed through a body 1 of electrically insulating material such as glass or ceramic, the lead wire 3, which is connected to the collector electrode 65, having a substantially greater cross-sectional area than the wires 2, 4, along its whole length or that part of its length which extends from the collector electrode to, or through, the body 1. For instance, wire 3 may have a diameter of 0.040 inch as against a diameter of 0.018 inch for wires 2, 4. The lead wire 2, which may be of either configuration shown or may comprise a single right-angle bend at the level of the emitter electrode 64, is sufficiently resilient to hold the crystal and electrode assembly in position relative to the lead-wires during manufacture. In the embodiment shown in Fig. 10, the lead wire 4 has the greater crosssectional area and.is connected to a base electrode 66 comprising a conductive plate having a central hole (not shown) through which the collector (or, in a modification, the emitter) electrode protrudes. In alternative embodiments, the wire 2, or the wires 2, 3 may be connected to their respective electrodes by means of an intermediate lead wire. The transistor is protected by a cylindrical cover 131, Fig. 14, a flange 132 of which seats on a flange 43 of a metal ferrule surrounding the glass or ceramic body, a skirt 42 of the ferrule being collapsed radially inwards over the flange 132 and the visible joint being soldered at 141. In an alternative embodiment, the ferrule comprises an annular lip in place of the flange 43, on to which lip the cylindrical cover seats. When the latter is metallic, the mating surfaces of cover and ferrule are tinned before engagement, and the visible joint between them is soldered; when the container is non-metallic, the solder is replaced by a hard-setting synthetic resin. Specifications 801,442 and 801,444 are referred to.

Abstract: 663,035. Washing granular materials. LITVINOV, N. Sept. 27, 1947. No. 26233/47. Class 82(ii). [Also in Groups I and V] The bottom of a gravity concentration appliance e.g. a launder table or sluice, is provided with a lining of thermoplastic material permanently bonded thereto, the lining being formed with a suitable recovery surface by means of a pressing tool when in the plastic condition and being regenerated, when worn, by similar means. The lining may be rendered plastic by flowing hot water over it and grcoves impressed therein by means of a cold tool, a preheated tool or a tool having heating means embodied therein such as a hollow container to receive incandescent metal, charcoal or hot water or electrical heating means; in the latter case, it may be a flat metal plate, Fig. 3, or a roller, Fig. 5. Prior to pressing, the contact surface of the lining and tool are coated with talc, graphite, chalk or other powder, liquid or paste to prevent sticking. Secondary grooves, Fig. 6, may be formed by spreading a wide woven fabric or net over the warmed lining and then applying the tool; or, recessed grooves, Fig. 7, may be formed by applying the tool a second time after placing: inserts 33 in the grooves formed by the first pressing. The thermoplastic material may be a phenolic resin, acetate or hardened paraffin wax. The lining may be formed with a groove 9, Fig. 1, and discharge pipe 7 and the table may be pivoted at 4 to facilitate cleaning, the groove and pipe being closed by a board 6, clipped in position, and a stopper 8, during use.

Abstract: 407,887. Spectacles. KEELER, C. H., 47, Wigmore Street, London. Sept. 25, 1933, No. 26390. [Class 97 (i).] In frames of the kind in which each of the sides, in addition to having the usual hinge for folding purposes, is provided with pivotal adjustment about a substantially horizontal axis so that the inclination of the glasses can be varied, the last-montioned pivotal joint is in the form of a tapered plug and corresponding socket arranged to be moved axially into locked relationship. As applied to metallic frames having the usual split rim 10, Figs. 1 and 2, with lugs 12, 13 drawn together by a screw to secure the lens, the frame is provided adjacent the lug 13 with a conical projection 14 surrounded by a conically-bored sleeve 17 having rearward projections or cheniers 18, 19 between which a chenier 21 on the side 20 engages. The projection 15 is internally threaded to receive a screw 16 by which it can be locked within the sleeve 17 after the inclination of the glasses has been adjusted. When applied to non-metallic frames, the sleeve 17 may be formed integrally with a plate 23, Fig. 3, secured to the frame 24. The tapered plug passing into the sleeve carries one member of the ordinary hinge of the side 20, this hinge consisting of a leaf 26 having cheniers interengaging with cheniers 27 carried by the plug. The socket 17 serves as an abutment to limit the outward movement of the side. The axis of the hinge 27 may intersect the axis of symmetry of the plug. In another form, Fig. 6, the frame 24 has a rearward projection 34 which receives a tubular bush 35 having a tapered bore into which the plug 15 fits. The pivotal joint for the side 20 may consist of a plate formed at one end with a number of cheniers extending into the thickness of the plate, the latter being cut away between adjacent cheniers to accommodate the chenier or cheniers carried by the tapered member.
