Abstract: 943,490. Refrigerating. GARRETT CORPORATION. May 31, 1960 [June 1, 1959], No. 19263/60. Heading F4H. [Also in Division F1] In a closed-circuit refrigerating system, vapour can be returned from the condenser 6 to the inlet of the centrifugal compressor 1 via a bypass pipe 12. The flow through pipe 12 is controlled in accordance with the flow through the compressor discharge pipe 5 by means of a valve 13 actuated by a diaphragm 31 exposed on opposite sides to the pressures developed in a Pitot tube 34 and a static tube 33. Alternatively, the control is in accordance with pressure or temperature. The by-passed vapour enters the compressor inlet through nozzles 15 which impart a tangential component of flow to induce swirl in the incoming vapour. If the swirl is in the direction of rotation of the compressor impeller, it causes the compressor head to vary substantially in proportion to the load. If the swirl is in the opposite direction, the compressor head remains substantially constant. The nozzles 15 may be adjustable in direction.

Abstract: 948,453. Logic circuits employing transistors and remanent magnetic cores. MULLARD Ltd. May 25, 1961 [June 1, 1960], No. 19410/60. Headings H3B and H3T. A logical AND circuit has its inputs A1, A2, Fig. 1, connected through transistors T1, T2 to opposed input windings W1, W2 on a core C of material having a rectangular magnetization characteristic, and an alternating output is induced in a winding W3 only when (a) both inputs are energized simultaneously by respective D.C. signals modulated by A.C. of opposite phase, (b) the two inputs are interlaced D.C. pulses which act in opposite senses in the windings W1 and W2, or (c) one input is a D.C. signal modulated by A.C. and the other a D.C. bias, each input being of sufficient value by itself to saturate the core. The core is unsaturated when an output is produced by coincident input signals, and the conducting transistors are arranged to bottom so as to obtain a substantially constant winding voltage and rate of change of flux. When one input only is energized, on the other hand, the core becomes saturated and the conducting transistor operates at a limited current value. An additional output winding W3<SP>1</SP> may be used to provide an output of opposite phase useful, for example, in cascaded logical circuits. In a modification, Fig. 3; providing the logical OR operation, winding W2 has parallel inputs A2 and A3, and an A.C. output is produced when a D.C. signal modulated by A.C. is applied to either or both inputs A2, A3, the input A1 being continuously biased by D.C. In a further modification, Fig. 4, a rectified feedback path to A2 which includes a smoothing circuit L maintains an output as long as a D.C. signal modulated by A.C. is applied to A1.

Filed: 1920-07-08
Abstract: 147,734. Junkers, H. Dec. 22, 1916, [Convention date]. Planes, construction of. - Planes for flying-machines are formed with lattice girder spans rigidly connected to a corrugated sheet-metal envelope without the. use of ribs or external bracing, the corrugations extending in the direction of flight. Figs 1 and 2 show longitudinal and transverse sections of a wing in which spars comprising upper and lower tubes 1, 2 united by vertical and inclined tubes 3, 4 are riveted directly to a corrugated metal envelope 6. Adjacent spars are connected together by diagonal braces 5. A modification is described in which the upper and lower booms are in staggered relation and braced only by diagonal members forming approximately equilateral triangles. The tubes taper in diameter or thickness of wall towards the wing tips. The leading edge of the plane where the curvature is sharp may be formed as a separate piece corrugated as shown in Fig. 17 so that the corrugations on the upper and lower surfaces of the plane are offset in order that they nest together at the rear edges of the plane, where they are secured over a wood filling-piece 28 as shown in Fig. 13. Alternatively, the leading edge may be made straight at the extreme front with gradually deeper corrugations towards its junction with the main surfaces, or it may be of trough form with straight edges joined to the main coverings, the corrugations of which diminish in depth towards the junction. The covering may be riveted directly to the tubes 1, 2 of the spars or to reinforcing-pieces 16 or 21, Figs. 8 and 10, clamped to the tubes. The covering may have an extra deep corrugation 9, Fig. 6, at intervals, or additional strengthening-pieces 10, corrugated at 11, may be applied to the surface either continuously on the outside or between adjacent spars on the inside.

Title: Method of cladding a metal core
IPC: B22F5/12
Filed: 1957-06-24
Abstract: 864,532. Powder metallurgy. COPPERWELD STEEL CO. June 24, 1957 [June 29, 1956], No. 19859/57. Class 82(1) [Also in Groups XXII and XXXVI] In a method of cladding a metal e.g. steel core a powdered metal having a lower melting point e.g. aluminium copper or mixtures largely of those metals is pressed on to the moving tensioned core, the cladcore then being rolled at a temperature below the melting point of the cladding metal to unite the metals without diffusion at the interface. The cladding metal has a lower tensile strength than the core metal and/or has a greater corrosion resistance. The composite rod wire or flat may be used for electrical conductors, fencing wire or concrete reinforcement. A steel core-rod 12, Fig. 1, drawn from a reel 11 is strengthened at 16 and cleaned at 17 by abrasion, a gas or a liquid before passing through a tube 20, Fig. 2, containing an aluminium powder 50 fed from a hopper 19 by a vibration-assisted gravity feed. The pressure rolls 24, Fig. 4, the peripheral speed of which is equal to that of the core 12 press the powder around the core and the clad-rod 12a is then inductively heated in a reducing atmosphere to a temperature between 950‹F. and 1180‹F. for from 1 to 10 minutes to plasticize the powder prior to passing the rod through rolls 24a which effect the bonding of the cladding to the core in a reducing atmosphere. No single pass of the rolls 24a reduces the rod by more than 10%. The clad-rod 12a may then be annealed prior to hot-reduction in a reducing atmosphere by rolls 24b. After hot-reduction the clad-rod 12a is cooled in a reducing atmosphere and then further reduced cold by rolls 24c with no single pass making a reduction exceeding 10% and annealing being carried out as required. The rod is then subsequently drawn down to its final diameter. In a modification the pressure-rolls, the induction heater and the bonding rolls are mounted so that the rod moves vertically, the clad-rod being subsequently further hot-reduced, by passing through further rolls, cooled and wound on a reel. When copper cladding is used the induction-heating range is 1800‹F. 1900‹F. and the hot-rolling reductions may be at 1600‹F.-1900‹F., annealing being carried out at 1300‹F.

Title: Method of Producing Slub Yarns.
IPC: D01H5/36
Filed: 1966-05-05
Abstract: 1,150,318. Slub yarns; woven fabrics. TEIJIN Ltd. 5 May, 1966 [7 May, 1965; 13 Jan., 1966], No. 19878/66. Headings D1F, D1K and D1W. A slub yarn is produced from a multifilament yarn by partially cutting the yarn along the length of the yarn to form cut filament ends in the yarn, and entangling the filaments ends with the filaments to form slubs. In one embodiment a yarn, if twisted appreciably, is untwisted, coated with a conductive materiale.g. water, a surfactant, or an electrolyte-, passed to an electrode having a voltage of 5000-100,000 volts to separate the filaments, and is then passed between a fixed member, and a movable member having a plurality of knives to cut some of the separated filaments when the member is intermittently moved into engagement with the fixed member which may also have a cutting knife. Each knife of the movable member has associated therewith a holding member which engages the cut filament ends and temporarily prevents them from travelling on with the uncut filaments so that the ends are sloughed up and when the filaments are twisted together by a ring spindle a slub yarn is formed. In modifications the yarn may be partially cut by means of a needle cutter reciprocated transversely of the yarn, the cutter having several notched cutting edges which intermittently cut some of the filaments, or by means of a reciprocating notched bar which separates groups of filaments from the yarn and brings them into contact with a cutting knife. The entanglement may alternatively be caused by a fluid jet through which the yarn may be overfed, by a rotating brush member, by passing the yarn between a fixed plate and a disc intermittently brought into engagement with the plate with the disc optionally being rotated and the engaging surfaces of the disc and plate being formed by a felt or an elastomeric or metallic sheet, by passing the yarn between a pair of shearing rolls which rotated in a direction opposite to the direction of the yarn about eccentric axes so as to intermittently contact the yarn, or by passing the yarn between a roll rotating at the same speed as and in the direction as the yarn and a plurality of smaller rolls arranged around part of the circumference of the bigger roll, rotating in the opposite direction of travel of the yarn, and optionally being reciprocated. The yarn may comprise one or more ends of polyethylene terephthalate, or a twisted ply of untwisted viscose rayon and untwisted polyethylene terephthalate. Fabrics described are plain woven and taffeta polyethylene terephthalate fabrics having a stub yarn as the weft.
