Title: Improvements in or relating to the production of materials for magnetic coils
Inventor: CHESTER PETER FRANCIS
IPC: B23K20/233
Filed: 1964-11-20
Abstract: 1124621 Jointing by rolling CENTRAL ELECTRICITY GENERATING BOARD 22 Sept 1965 [20 Nov 1964] 47408/64 Headings H1A and A4D A composite conductive material is made by mechanically working together a super-conductor and another conductive material to distribute the super-conductor as layers, filaments or ribbons in a matrix of the other material. Materials for the super-conducting portions are the binary alloys niobium-titanium and niobium zirconium and ternary and quaternary alloys containing niobium and titanium or niobium and zirconium. Materials for the matrix are copper, silver, aluminium, indium and cadmium. The composite material is used for magnet windings at a temperature such that the matrix material is normally conductive. Such materials, when incorporating type II superconductors, are claimed in divisional Specification 1124622. In making one material, alternate foils of copper and niobium-titanium are stacked and enclosed in a tight-fitting copper box which is welded or soldered in vacuo or in an inert atmosphere. The material is then hot-rolled parallel to the plane of the foils - the heat bonds the foils but the temperature should be low enough that no eutectic formation or other reaction occurs. Subsequent rolling reduces the thickness to 0À001 inch. Strips ¢ inch wide, are stacked on top of one another and then edge rolled to produce a foil 0À001 inch thick and several feet wide in which a large number of alloy threads or ribbons are formed in a copper matrix. The material is then annealed. The alloy threads may no longer be continuous but the composite material still has a very low resistance when the threads are superconductive. In another example a niobiumtitanium sheet is provided with a plurality of parallel slots. The sheet and a superimposed copper sheet are rolled up parallel to the slots and vacuum sealed in a tight-fitting copper can. The material is hot-rolled and then cold-rolled parallel to its axis and the rolled material annealed. The Nb-Ti filaments produced in this material are less than 0À001 inch thick. In alternative methods one material may be plated on the other and the composite rolled, or wires of one material may be interleaved with foils of the other before rolling. Material for the end windings of a magnet (where there is an appreciable field component transverse to the plane of the strip) may be made so that the planes of the constituent foils lie at an angle to the plane of the final strip. A material which may be subjected to many field orientations is made so that its component materials lie in whirls, corrugations or ripples in the product. This may be  achieved by loosely stacking simple or composite foils and edge rolling so that crushing occurs.

Abstract: 1331764 Fluidic servosystems; Fluid oscillators ATOMIC ENERGY OF CANADA Ltd 8 Oct 1970 [24 Oct 1969] 47967/70 Headings G3H and G3P [Also in Division G1] A monostable fluidic switch 10 providing an oscillating signal in outlet 19 of frequency proportional to the liquid level 16 in dip tube 15 delivers fluid into the tube until the back pressure switches the fluid to outlet 19. Where the pressure in the tube falls, e.g. via a vortex vent, to a predetermined value, the fluid is switched back into the tube; the cycle then repeats. The pressures at which the fluid is switched from and to the tube are chosen so that switching occurs on the first relection of the compression or expansion wave from the liquid surface. A lateral control port can be added to admit a signal which will maintain the fluid flowing to outlet 19 until a measurement of liquid level is required. In this latter case a feedback to the control port ensures that a single output pulse is provided, and the period of this pulse is measured. In another embodiment (Fig. 4) a bi-stable switch 40 is used to measure a liquid level. In Fig.5 (not shown) a difference in levels is measured using a bi-stable switch. Tube 15 can be coiled and the output can be fed through a diode and an amplifier, and may control the liquid level. The liquid could be a mercury column in a temperature sensor. In a pressure sensor, the switch can detect the position of a piston in a cylinder.

Abstract: 1,155,604. Coating yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 31 Oct., 1966 [16 Nov., 1965], No. 48628/65. Heading D1L. In the application of a liquid or paste intermittently along the length of a yarn, the yarn 1 is taken from a supply 2 thereof, forwarded to a zone defined by the reciprocating motion (normal to the yarn path) of at least one nip formed by surface portions of two contrarotating bodies, caused to traverse to and fro in a direction normal to the yarn path in said zone, has liquid or paste applied intermittently by the surface portions forming the nip when the yarn is engaged thereby and is wound up, the speed of the yarn in said zone being substantially the same as that of the peripheral speed of surface portions forming the nip in the zone. As shown yarn 1 from supply package 2 is passed through traversing guide 5 prior to being passed between a pair of intergeared helically grooved rubber rollers 6 and 7, each a mirror image of the other, and thence to a second traversing device 8 and finally to a cylinder 9 where it is wound into package 10. The helically grooved rollers 6, 7 have surface portions 11, 12 which form a series of nips across the rollers and the surface portions of roller 7 are in contact with a train of plain rollers 13, 14 the lower of which is partially immersed in a bath 15 containing the liquid or paste to be applied. The rollers 6, 7 may be replaced by skewed elliptical cams and the traverse motions of guides 5 and 8 can be arranged so as to produce a completely random application of liquid or paste to the yarn 1. The liquid or paste may be a dyestuff or pigment or it may comprise an agent for modifying the dyeing characteristics of the yarn and the yarn may be subjected to a "fixing" treatment e.g. a heat treatment such as steaming, after application of the liquid or paste.

Abstract: 1479911 Rotary positive-displacement fluidmachines TRW Inc 12 Nov 1974 [5 Dec 1973] 48913/74 Heading F1F In sliding-vane positive displacement machine leakage between high and low-pressure inter-vane cavities C4, C1 is minimized by a cylinder 44 pivotally supported on a fixed shoe 48, and held against the rotor periphery 46 by the working-fluid pressure in a contracting cavity C3. The shoe has a nose 48a engaging with a recess 50 in a plate 51 attached to the cylinder and securing a reed-type outlet valve 54. Owing to loss of pressure caused by fibrous strips 57, 60 in the path of the fluid between the valve 54 and an outlet port 20 the pressure in a main outlet chamber 56 is appreciably less than that in the cavity C3, which is thus able to hold the cylinder against the rotor. The strips 57, 60 coalesce oil entrained with the fluid and the oil drains from the strips into a pool P whence it returns to bearings 26, 34 and the vanes 39 through a passageway 68. To facilitate relief of excess pressures in the inter-vane cavities a plate 61 may be held against the cylinder by springs, Fig. 10, (not shown), and the said pressure in the chamber 56. To reduce back-pressure holes 55a may be formed in the cylinder on the upstream side of the outlet valve. An inlet port 19 may be furnished with a non-return valve, (72) Fig. 4 (not shown), and filter (74). The port 20 may have a pressure-relief valve (21). The vanes may have pivoted spring-loaded slippers 40.
