Title: Magnetic bubble domain system
IPC: G11C11/14
Filed: 1973-02-14
Abstract: 1411338 Moving domain systems INTERNATIONAL BUSINESS MACHINES CORP 14 Feb 1973 [27 June 1972] 7132/73 Heading H3B In a bubble domain system the operating margins of the bubble device i.e. the range of usable control signals such as the bias field, are increased by applying a thin magnetic sheet to parts of the device. Fig. 2 shows how in a bubble domain device in which several functions are performed, e.g. bubble generation, propagation, switching or splitting, each function can only be performed over a range of lines and rotating field values; the whole set of functions can only be performed if there is an area within all the curves. As can be seen in Fig. 2 the operating margins for splitting are very small, and lie outside the area common to the other curves. However if a permalloy sheet is applied to the device in the region where splitting is to occur, the margins are increased and the whole curve is moved upwards to a position better located relative to the other curves. A bubble splitter is shown in Fig. 5, and is of a known form which breaks domain BD into two parts; a thin permalloy layer 56 applied to the device is found to modify the margins as stated above. Such a layer may be localized as shown, or in the case of parallel propagation paths a strip of the material may cross all the splitters on the device, Fig. 6 (not shown). Similar layers may be. applied to any other part of the device to increase the margins for generation, corner propagation &c., Figs. 3, 4, 6 (not shown). Fabrication.- Bubble devices generally are made by depositing an insulating SiO2 layer on a bubble domain material, then depositing a thin permalloy sheet on the insulation; the sheet is etched away except where magnetoresistive sensors are required. In the invention the sheet is also unetched where the margin-increasing layers are required. The normal propagation elements, e.g. I and T bars, are then deposited through a mask, and conductors plated through a photoresist mask. If desired, the thin permalloy sheet may be etched after deposition of the propagation elements and conductors rather than before. A passivating layer, e.g. glass, is finally placed over the whole device.

Title: Improvements in interpolymers
IPC: C08F22/28
Filed: 1949-03-16
Abstract: Copolymers are produced by heating a di-2-propenyl itaconate with a mixture of from 0.1 to 6 molar equivalents of styrene or a substituted styrene and from 0.1 to 10 molar equivalents of a 2-propenyl chloride at temperatures in the range of 25-120 DEG  C., preferably 50-110 DEG  C. and for times sufficient to effect an adequate degree of reaction, e.g. 1 to 100 hours.  The course of the copolymerization may be followed by noting the increase in viscosity of the reaction mixture.  The heating may be conducted in the presence of an organic peroxide catalyst such as acetyl p  peroxide, benzoyl peroxide and tertiary butyl hydroperoxide in the proportion of 0.1 to 20 per cent by weight of the reactant mixture.  The di-2-propenyl itaconates are esters of itaconic acid with alcohols having the formula R.CH=CH1-CH2OH and the 2-propenyl chlorides have the structural formula R.CH=CR1-CH2Cl, where R is hydrogen, chloromethyl, lower alkyl or phenyl, and R1 is hydrogen, chlorine, chloromethyl, hydroxymethyl or lower alkyl, preferred esters being the allyl and methallyl esters and preferred chlorides being allyl chloride, methallyl chloride, 2,3-dichloropropene and 2-(chloromethyl)-allyl chloride.  The styrene derivative may be alpha-methyl styrene or a styrene which is nuclearly substituted with lower alkyl, lower alkoxy, halogen or lower haloalkyl.  The products may be purified by repeated solution in a solvent such as acetone and reprecipitation with a non-solvent such as n-hexane and may be moulded to form rods or sheets or dissolved in organic solvents, particularly hydrocarbons, and used as coating, laminating and impregnating compositions.  The copolymers, by the application of heat and/or a catalyst can be converted to an insoluble infusible state by further polymerization or by copolymerization with other polymerizable organic compounds such as tolyl acrylate, butyl methacrylate, vinyl butyrate, allyl acrylate, diethyl fumarate and diallyl fumarate, and dyes, pigments, fillers and plasticizers may be incorporated with the copolymers at the soluble fusible stage prior to the final cure. Specification 661,292 is referred to.

Abstract: 783,091. Knitting. WILDT & CO., Ltd. March 3, 1955 [March 15, 1954], No. 7459/54. Class 74 (2). The wrap thread embroidery pattern of the integrally knitted top 2 of a seamless sock or the like faces outwardly when the top is in its folded-over condition and, to this end, the loops forming the top and those forming the leg and instep are drawn to opposite faces of the fabric. The top may be plain, purl, or rib. The embroidery stitches may occur in even courses in certain wales and in odd courses in other wales. The loops of the heel 6 and toe 9 are drawn to the same face as those of the top. The sole 8 may also be reversely knitted ; or both it and the instep may be tubularly knitted in the same way as the leg. The leg and instep, at least, may be rib knitted. Those loops of the leg and instep which are to face outwardly in wear may be knitted on the upper cylinder of a superposed cylinder machine, so that the finished article has to be turned inside-out, the heel and toe being knitted on the lower cylinder. The superposed cylinder machine has a verge ring 24 movable up and down automatically, to adjust the rib loop length as necessary when knitting purl, rib, or selective transfer designs. To this end, it is mounted at the bottom of a tube 23, to the top of which is secured a disc 25, peripherally grooved for engagement by a pin 30 at one end of a lever 28 rocked through linkages, by cams on a control drum. The ring 24 is, for each needle, provided with a trick 24a and a recess 24b which prevents cutting of the rib loops. The wrap threads WT are fed to the lower cylinder needles by wrap instruments 19 mounted in tricks in a cylinder 18 rotating with the top needle cylinder. In all positions of the verge ring, there is room for the operation of the wrap guides. Specifications 455,801 and 526,963 are referred to.

Abstract: 663,064. Supersonic inspection devices. SPERRY PRODUCTS, Inc. March 12, 1948. [April 26, 1947] No. 7574/48. Class 118 (ii). [Also in Group XXXIX] In a pulse echo method of testing a solid plate 10 for the presence of a defect 11 a beam of pulsed supersonic vibrations generated by a piezo-electric crystal transducer 12 is projected onto one surface 13 at an oblique angle to produce a beam of shear waves in the plate which is successively reflected by the opposite surfaces 13 and 14 until the defect 11 is encountered when it is returned to the transducer by another series of multiple reflections. The crystal 12 is mounted on a wedge 20 of material, e.g. polystyrene, having a lower acoustic impedance than that of the plate and in order to prevent the transmission of longitudinal waves through the plate the angle of the wedge is chosen so that the angle of incidence is intermediate between the critical angles for longitudinal and shear waves and is also preferably fixed in relation to the thickness of the plate and the width of the beam in the plate so that the outgoing beam in the plate traverses the whole longitudinal cross section of the plate with no "strip" or overlap areas, Figs. 5 and 6 (not shown). In order to prevent multiple reflections within the wedge, the wedge may be made of absorptive material. The transmitted and echo pulses may be displayed on a cathode-ray tube as described in Specification 641,095 and the method is also applicable to testing curved plates, e.g. pipes, Fig. 4 (not shown).

Filed: 1942-06-04
Abstract: 557,916. Control systems for arc furnaces ; protective cut-out arrangements. REYROLLE & CO., Ltd., A., LEYBURN, H., and ALDERSON, R. June 4, 1942, No. 7605. [Class 38 (iv)] [Also in Group XXXVII] In an arc-furnace control system A having its supply volts reduced in operation from 160 or 200 volts down to 100 volts by a variably-tapped transformer primary B, and the circuit breaker C opened at each tap-change, the duty on the breaker is minimized by lifting the electrodes by means not shown and reducing the current so that underload relays G1 ... G3 close and, with the operator's switch F engaging contacts F<SP>2</SP>, energize the breaker trip coil C2. The dosing coil C' is energized by moving handle F on to contacts F<SP>1</SP>. An emergency trip switch M is also provided. In Fig. 2, when F is moved to tripping position, a contactor N with holding contacts N' is energized to prepare the trip circuit and supplies over circuit O a motor for lifting the electrodes, the contactor N being de-energized by the opening of the breaker. Protective systems.-The circuits of the undercurrent coils G1 ... G3 include also the windings of overcurrent relays, of which J1 ... J3 have low settings and long time delays and K1 ... K3 have high settings and short delays, the former being mainly employed during the initial period when small overloads of relatively-short duration would produce frequent tripping. A resettable earth-breakage relay L has trip contacts L1 in parallel with the parallel-connected overload contacts, and a contact L2 in the closing-coil circuit to prevent reclosure until attention has been called to the fault.

Abstract: 657,875. Making turbines. SULZER FRERES SOC. ANON. March 22, 1949, No. 7720. Convention date, April 21, 1948. [Classes 83 (ii) and 83 (iv)] Uniting by fusion.-In a method of welding sections of turbine rotors and the like along annular seams the parts are first tack-welded and then welded between the tacks in a furnace which is at a temperature below the welding temperature, the tack welds and ends of the welding runs being then removed and the gaps thus produced being finally welded. Two adjacent sections 5, 6, Fig. 2, of a turbine rotor are centred at cylindrical faces 7 by a ring 8 and are axially located by removable pins 18 in the ring, so as to provide spaces 9<SP>1</SP> between the parts 5, 6 which close when the welds 10 finally contract. The pins are removed after the tack welds are made and the rotor is inserted in the furnace for completion of the welding. Closable apertures are provided in the furnace wall to permit access to the work which is slowly rotated during welding. Abutments 17 engage when the rotor is assembled and are deformed as shown in Fig. 3 during final contraction. In a modification, faces 14, Fig. 4, and the deformable flanges 17 may abut a locating-ring 13 which centres the sections on its outer face 12. An even number of uniformly-spaced tack welds is preferable, diametrically opposite tack welds being made simultaneously and in welding between the tack welds the next succeeding run is made between the diametrically opposite pair. Further welding runs may be made over the first and the whole may be finally heat-treated.
Patent GB-1421987-A (GB)
Title: Fuel element for high temperature reactors
IPC: G21C3/28
Filed: 1973-02-16
Abstract: 1421987 Fuel elements NUKEM GmbH 16 Feb 1973 [25 Feb 1972] 7751/73 Heading G6C A fuel element for a high temperature reactor comprises a graphite block formed with bores within which fuel inserts fit without intervening gaps. The fuel inserts each consist of coated fuel particles within a graphite matrix. They are produced by pressing from the coated fuel particles and a matrix powder mix and, in one method, the green pressings thus obtained are introduced into the bores in the graphite block. During the subsequent coking and heat-treatment operations, these inserts expand and fit tightly without gaps into the bores. The composition of the pressing powder is such that the resultant matrix has as high a thermal conductivity as the graphite block and that no gap is formed between the insert and the block during reactor operation. This is achieved by virtue of the fact that, from the beginning of fuel exposure onwards, the matrix expands more than the block, contracts less than the block or expands while the block contracts, with the result that at no time during operation of the reactor is a gap formed. The matrix consists of natural graphite alone or with at most 15%, preferably less than 10%, by weight of binder. With such a binder content, expansion of the matrix occurs on coking. In a further embodiment, the graphite matrix also contains up to 25% by weight electrographite and up to 25% by weight binder (the remainder of the matrix being natural graphite). The binder used for the matrix preferably consists of a readily graphitized material such as coal-tar pitch. In an alternative method, the fuel inserts are coked and calcined on their own and only thereafter introduced into the block. The matrix in this case consists of natural graphite with less than 5% by weight of binder. The fuel inserts can be additionally provided with a thin fuel-free shell. Because the matrix is selected to undergo greater thermal expansion than the structural graphite, the fuel inserts  fit tightly in the bores without any gaps when the fuel element is heated to its working temperature in the reactor. Any stresses in the matrix are quickly dissipated by creeping so that they never become critical.
