Patent GB-1181180-A (GB)
Title: Superconducting Magnet
IPC: H01F6/06
Filed: 1968-12-17
Abstract: 1,181,180. Superconductors; superconducting, magnets. UNION CARBIDE CORP. 17 Dec., 1968 [21 Feb., 1968], No. 59908/68. Addition to 1,140,696. Headings H1K and H1P. A superconducting electromagnet comprising superposed layers of interlocked particles in a matrix of superconducting material, and non- superconducting material, respectively, as claimed in parent Specification 1,140,696, is characterized in that each successive superconducting layer overlaps the end of the preceding one and generally surrounds it so that the superconducting layers are series connected to form a basically spiral configuration about a former which may be of cylindrical, conical or race track form. A number of such configurations may be arranged about a working space, e.g. two saddle-back configurations disposed as shown in Fig. 2, to provide a field normal to the axis of a cylindrical working volume. The race track configuration shown in Fig. 3 is formed by rotating an oval copper former about an axis in front of a plasma jet spray gun, movement of which is automatically controlled to maintain it at fixed distance from the former surface. During the first rotation powdered alumina is fed into the plasma to form an incomplete oval of insulation. After indexing the gun forward into the gap niobium-tin particles are fed into the plasma and deposition continued to form an incomplete oval of superconductor. The process is then repeated with copper fed into the plasma and the sequence of operations continued until the structure of overlapping layers shown is complete. The edges of the structure are then trimmed to remove any metal bridging the insulation layers. Between successive depositions the gap in the last deposited layer may be cleaned of any extraneous deposited material by grit blasting.

Abstract: 1393255 Setting wool yarn CIBA-GEIGY AG 21 Dec 1972 [29 Dec 1971] 60368/71 Headings D1F and D1P A 2-ply or 3-ply wool yarn having an average degree of twist of 6 to 12 turns per inch is set by treatment in an aqueous solution with 0.5 to 8% by weight of hexamine, based on the weight of yarn, at a pH of from 5.5 to 8.5 and a temperature of 90 to 105‹C until the setting efficiency is at least 70%. The efficiency is calculated by expressing the twist remaining in a dried yarn which has been suspended under a 10 gram load in water for 24 hours, as a percentage of the original yarn twist. The yarn is either all wool or a wool blend. The amount of hexamine is preferably from 2% to 4% and the pH is preferably from 6.5 to 7.5. The yarn may be treated by heating a hexamine solution to 100‹C and immersing the yarn, by adding the hexamine and then the yarn to water at 100‹C or by immersing the yarn in a cold hexamine solution which is then heated. The yarn may be padded through the solution to give an approximately 100% moisture pickup, partially dried (e.g. to 30% moisture content) and then steamed (e.g. for 10 to 30 mins. at atmospheric pressure). Examples of the treatment of all wool yarns, and woolnylonyarns are given.

Abstract: 1276708 Cathode-ray tube circuits INTERNATIONAL BUSINESS MACHINES CORP 30 Dec 1969 [14 Jan 1969] 63207/69 Heading H4T  In a cathode-ray tube deflection circuit employing two inductively coupled windings 12, 16 (Fig. 1) for one deflection direction, winding 12 being driven by a ramp driver 14 supplied with a ramp voltage waveform (A, Fig. 2) at terminal 47 and winding 16 being supplied from a bias driver 18 with positive voltage V 1  to produce a shift deflection current which may be adjusted by potentiometer 32, pulses 74 (C, Fig. 2) which, in the absence of the present invention, would be induced in winding 16 by the fly-back pulses 72 (B, Fig. 2) are neutralized by utilizing the pulses 72 to control a pedestal driver 20 which increases the voltage supplied to (the top of) winding 16 by a suitable amount. To prevent the transistors in the pedestal driver 20 from being driven into saturation a diode 48 clamps the voltage waveform B at 3V 1 . Capacitors 64 and 66 (which are optional) increase the speed of operation, capacitor 64 turning on transistors 52, 54 before transistor 50 turns on to drive 52, 54 and capacitor 66 controls the decay of the voltage at the bases of 52 and 54 when the flyback pulse 72 is dying out. Additionally capacitors 64 and 66 round off the waveform applied to the top of yoke 16 by preventing the formation of the respective "spikes" 76, 78 (C, Fig. 2) so that it more nearly matches the induced pulse in the yoke. Potentiometer 44 controls the amplitude of the ramp waveform.
Patent GB-2000674-A (GB)
Title: Chewing gum
IPC: A23G4/06
Filed: 1978-07-06
Abstract: A chewing gum having long-lasting sweetness, good sweat resistance and good processibility characteristics includes a water-soluble phase formed of aqueous softener, such as sorbitol, xylitol or maltitol syrup, and a first sweetener, such as sorbital or sugar, in particulate form dispersed throughout the aqueous softener, and a relatively water-insoluble phase formed of a plurality of separate and distinct masses suspended in and dispersed throughout the water-soluble phase, each of the masses being formed of particles of gum base and particles of a second sweetener, such as mannitol and/or sorbitol or sugar, enveloped by particles of gum base. The first sweetener and aqueous softener provide the initial impact of sweetness while the gum base provides an envelope or protective vehicle for the second sweetener, thereby providing extended sweetness after the initial sweetness impact has subsided. The relatively water-insoluble phase and/or the water-soluble phase may further include hydrogenerated starch hydrolysate which functions as a binder, without detracting from sweetness, to improve cohesivity and processibility and allow for sheeting of the chewing gum and the manufacture thereof in stick form. Other conventional ingredients may be present and the softener may include a thickening agent. The above chewing gum is prepared by mixing the melted gum base with the second sweetener, mixing the resultant mass with the first sweetener to tear the mass into discrete pieces, and adding the softener.

Title: Laminated Blades for Turbomachines
IPC: F01D5/34
Filed: 1978-12-29
Abstract: A blade, e.g. for the turbine of a gas turbine engine, is built-up of a series of laminations 62 bonded together and is cooled by a cooling flow which is supplied to interior cavities 74 of the blade, and eventually discharges through the working surfaces of the blade into the main fluid stream of the a turbomachine. The passages 84, 86 through which the cooling flow passes in reaching the surface of the blade are formed by etching away selected parts of each lamina to a reduced thickness, before assembly of the laminae into a complete blade. As shown, the convex side of the blade is internally cooled by the impingement of flows of cooling fluid from openings (84) against the inside of the blade wall; the cooling fluid then passes through passages (86) to be discharged at the concave side of the blade, at a shallow angle to the main fluid flow, to provide film cooling. Each exhaust opening (86) has a groove-like continuation (86) on the blade surface to the next downstream discharge opening. The blade may formed by an assembly of laminations which extend longitudinally of the blade. <IMAGE>

Patent GB-2040399-A (GB)
Title: Valve rotator
IPC: F16K29/00
Filed: 1979-01-11
Abstract: Valve rotators are known having balls in circumferentially spaced open-topped pockets formed in the annular rotator bodies, each pocket having a sloping track surface which is bounded by two curved side walls spaced from one another radially of the body and by two end walls. These known valve rotators are known to fail because the valve springs can exert such a high load on the various balls that the respective tracks become indented; these indentations cause the balls to be not completely free to ride up their respective tracks. The present invention firstly replaces the open-topped, but otherwise closed, pockets by ones 11 which are additionally open at their radially outer sides and, secondly, replaces balls by rollers. The rollers are kept in the pockets by part 17 of the coacting race 4. The new pockets are more easily made than the old ones and track-indentation is eliminated. <IMAGE>
