Title: Improvements in or relating to endless chain conveyors
IPC: B65G23/14
Filed: 1961-03-03
Abstract: 952,098. Endless conveyers. A. OELLRICH, [trading as MASCHINENFABRIK UND EISENGIESSEREI A. BEIEN]. March 3, 1961 [March 4, 1960], No. 7896/61. Heading B8A. A conveyer comprising boxes 1 having side rollers 2 running on rails 3 and drawn by a chain 10, is driven by means of jaws 14, 14<SP>1</SP> which are carried by the links of an auxiliary driving chain 6 and are moved into, and out of, gripping engagement with links of the conveyer chain 10. On their straight run between the chain wheels 7, 7<SP>1</SP> of the driving chain 6 the jaws 14, 14<SP>1</SP> are urged into gripping engagement with the respective links of the conveyer chain 10 by the action of cam surfaces 22, 23 (Fig. 5). At each end of this run where the jaws have to move into and out of gripping relationship with the chain 10 the surfaces 22 and 23 widen apart to permit the jaws to be opened by the action of a spring 25. The pivot pin housings of the driving chain 6 are formed with sockets to accommodate springs 15 (Fig. 7) between which portions of the jaws 14, 14<SP>1</SP> are disposed. The arrangement is such that the jaws can move in the direction of movement of the chain or in the opposite direction against the action of the springs 15, 15. The jaws 14, 14<SP>1</SP> are moved in this way prior to engagement with the conveyer chain 10 by the action of cams 33, 34 (Fig. 5), these act on followers 29, 29, carried by respectively crank members 28 each pivotally mounted at 27 on bosses formed on links of the chain 6. The members 28 have apertures in engagement with extensions 32 of the jaws 14, 14<SP>1</SP>. The cams 33, 33 actuate for one direction of travel of the chain 6 and the cams 34 act for the reverse direction of this chain. One or other of the sets of cams 33 or 34 is set into operative position by the action of a linkage automatically in accordance with the direction of the driving motor by suitable linkage (Fig. 8, not shown). In a modification (Figs. 2 and 3, not shown), the coil springs 15 are replaced by rubber springs. Also the cam surfaces 22, 23 are replaced by a single longitudinal cam member disposed between downwardly extending tails of the jaws 14, 14<SP>1</SP>. This cam surface holds the jaws in gripping position until the point of release when the jaws are engaged by further surfaces which guide them to the open position and extend around the axes of the driving wheels 7, 7<SP>1</SP> of the chain 6.

Abstract: 642,522. Knitting. COLE, B. T. R. REYMES-. March 30, 1945, No. 8102. [Class 74 (ii)] During the production of each of closelyrecurrent courses that alternate with intervening courses, a stretch or tension is applied to the loops of closely-recurrent wales that alternate with intervening wales; and during the production of each of the intervening courses, the stretch or tension is applied to the loops of the intervening wales. Sinkers 4 are urged inwardly by one or other of two spring rings, 5a, 5b. The sinkers are of two kinds and may recur in, say, a 1 Î 1, 1 Î 2, 2 Î 2 or 2 Î 3 sequence, those sinkers of one kind being cut away to miss one ring 5b, and those of the other kind being cut away to mix the other ring 5a. One ring is rendered ineffective in alternate courses, and the other ring ineffective in the intervening courses, e.g. by two series of bellcrank or other levers 7, pivoted on the sinker ring 2 and having butts 7a, 7b alternately engaged in succeeding courses, in the vicinity of the knock-over point, by cams such as 8a, 8b movable to and fro. In a modification (not shown) the loop tensioning is effected by urging selected needles outwardly at or subsequent to the knock-over, e.g. by a disc or wheel located inside the needle circle and having its periphery notched to accommodate spaced needles; the disc may be driven by engagement with the needles. During reciprocatory knitting, the alternating selection is suspended, so that all sinker loops or needle loops of a course receive like treatment.

Title: Improvements in electric welding
IPC: B23K25/00
Filed: 1943-05-22
Abstract: 564,231. Making chains &c. LINDE AIR PRODUCTS CO. May 22, 1943, No. 8158. Convention date, May 22, 1942. [Classes 83 (i), 83 (ii) and 83 (iv)] Uniting by fusion; casting.-Chain links, bars, rods and like ferrous articles are electrically welded by enclosing the parts at the joint in heat conducting separable moulds co-operating to form a work-receiving recess conforming to the work, placing unbonded granular fusible mineral welding material in the recess and between the parts of the joint, inserting a metal weld rod and passing an electric current through the rod, material and work to melt metal from the rod and at least a part of the mineral material so that the molten metal coalesces with the melted portion of the work. Chains may thus be welded without altering the overall dimensions thereof in contradistinction to a forged or resistance weld and may be made from corrosion resisting or high tensile steels. The mould may consist of a pair of rectangular copper blocks M, M<1>, formed on their front faces with grooves 14, 141 to receive one of the links L of the chain, the ends of the links of which are bevelled and in contact with each other so as to form a welding groove 60. Intersecting the grooves 14, 14<1> in the blocks at their upper edge and central of the blocks are recesses 16 with sloping rear and side walls to form a hopper through which the granular welding material G is introduced. Passages 30 for cooling fluid extend through the blocks parallel to the grooves and are provided with inlet and outlet conduits. 'The welding metal is provided by an electrode R inserted into the welding material with its lower end in operative relation to the extremities of the link and an electric current is then passed therethrough to the link. The fused welding material G by the circulation of cooling fluid through the blocks solidifies as a thin film on the walls of the recess 50 to form a heat insulating layer so that the molten metal will fill the space between the ends of the link to the contour of the recess. In another form, particularly for welding a stud link chain, the mould blocks, which are provided with a lap joint, are separated by apertured gaskets W from blocks B, B<1> to which they are bolted and which are secured to links 102, 104 provided with studs 106 mounted on a pivot 108 and connected by links 124, 128 to a crank 114, which is pivoted at 116. The arm 126 is connected to the piston P of a pivotally mounted cylinder A and a lost-motion connection between the links 124 and 102 is provided. The mould blocks are cooled by fluid circulated through passages 94, 88. The mould blocks have in addition to the matching grooves 74 to receive the ends of the link, matching grooves 82 to receive the stud S. The welding circuit is completed by studs 132 carried by the links 102, 104 and engaging the link L.

Title: Semiconductor integrated circuit
IPC: H03K19/091
Filed: 1975-02-18
Abstract: 1503232 Integrated circuits TEXAS INSTRUMENTS Inc 18 Feb 1975 [19 Feb 1974] 08290/77 Heading H1K [Also in Division G3] The subject matter of the present Specification is substantially the same as that of the parent Specification but the claims are concerned with the construction of the integrated injection logic (I<SP>2</SP>L) circuit module comprising the timekeeping means of the electronic timepiece (see Heading G3T). The logic circuitry is implemented in levels 1-3 (Figs. 2a, 2c) interconnected by diodes 800, 801. The gate cell depicted in each level includes a P-type B-doped substrate 806 overlaid by a lower resistivity epitaxial layer 807, N+ antimony doped DUF (doped underfilm) layer for lowering emitter resistance. P+ isolation diffusion areas 803 isolate and define each logic level. N+ regions 808 extend into boron doped P-type regions 901. Regions 900-810-901 form the lateral PNP transistor used as the injector, the region 900 serving as the emitter. Regions 808-901-810 function as an inversely operated vertical NPN transistor. Regions 901 serve as the collector of the PNP lateral transistors and the bases of the vertical NPN transistors. Each region N serves as a common base for each of the lateral transistors and a common emitter for each of the vertical transistors. Diodes 800, 801 interconnect the logic outputs of logical elements in one level with logic inputs of elements in another level. As shown in Fig. 4b each emitter strip 900A has a portion 900B extending transversely. The length and width of the extension are selected so as to provide an appropriate emitter periphery and area to control the amount of injected current into P-type regions 901a. Grading of the power supplied to various flipflops in the circuit, is accomplished by selection of the appropriate sizes of emitter strip extensions. The module may be constructed using Schottky TTL type processing, e.g. using photolithographic technique.
