Title: A process for cross-linking of high molecular weight organic materials
IPC: C08K5/1565
Filed: 1962-07-23
Abstract: Polyaddition and polycondensation products are cross-linked by heating to 100 DEG  to 220 DEG C. with a peroxide of the general formula: <FORM:0960319/C3/1> in which R is a hydrogen atom or an alkyl radical containing 1 to 4 carbon atoms and X is an aliphatic hydrocarbon radical, a cycloaliphatic radical or the group: <FORM:0960319/C3/2> Peroxides mentioned are mesityloxide-peroxide; 3-ethyl-peroxy-3, 5, 5-trimethyl-dioxolane-(1,2); and 3-tert-butyl-peroxy-3, 5, 5-trimethyl-dioxolane-(1, 2).  These peroxides may be used in conjunction with other known peroxides e.g. di-tert-butyl peroxide.  The amount of peroxide used is generally 0.5 to 10% by weight, calculated on the weight of polymer.  Polyaddition products mentioned are polymers of a -olefines and copolymers thereof with vinyl esters; homopolymers of acrylic esters and copolymers thereof with vinyl esters or methacrylic esters; homopolymers of conjugated diolefines and copolymers thereof with a -olefines &c. Mixtures of ethylene-vinyl ester-copolymers and polyethers e.g. polytetrahydrofuran, polyethylene oxide and polypropylene oxide, may be cross-linked. Polycondensation products mentioned are unsaturated polyesters especially those based on a , b -unsaturated dicarboxylic acids and polyhydric alcohols; polyesters which have been lengthened with polyisocyanates e.g. reaction products of linear hydroxyl-group containing condensation and/or addition products with diisocyanates and glycols.  In the cross-linking process, the peroxides and if desired other additives, are mixed into the high molecular weight compounds either in solution or in the solid state.  In one embodiment of the invention copolymers of ethylene and vinyl esters or ethylene and propylene are cross-linked with the above peroxides in the presence of small quantities of compounds which contain several olefinically unsaturated bonds and which have at least two unconjugated polymerizable carbon-carbon double bonds, the prepared compounds containing three allyl groups; many other suitable compounds are mentioned, including olefinically unsaturated polyethene, polyurethanes of polyisocyanates and olefinically unsaturated alcohols, and unsaturated polyesters.  In addition sulphur or compounds which split off sulphur may be present.  The polymers to be cross-linked may contain fillers.  The copolymers may be foamed before or during vulcanization, e.g. by adding a gas under pressure and subsequently releasing the pressure or by heating mixtures of these copolymers with easily volatile solvents. Alternatively blowing agents may be used e.g. alkali metal carbonates or organic compounds such as azodiisobutyric acid dinitrile, aromatic sulphohydrazides and nitroso compounds.

Title: Improvements in and relating to gas-blast electric circuit breakers
IPC: H01H33/70
Filed: 1952-11-10
Abstract: 733,444. Gas-blast switches. GENERAL ELECTRIC CO. Nov. 10, 1952 [Nov. 9, 1951], No. 28261/52. Class 38 (5). A gas-blast switch has spring-biased movable interrupting contacts 12 co-operating with one end of a tubular fixed conducting member 15, a movable tubular isolating contact 17 coaxial with but spaced from the member 15 and bridging contact members 20 normally interconnecting the other end of the member 15 and the isolating contact 17. When the gas-blast is applied to the switch, the blast initially opens the contacts 12, 15 and the blast is exhausted upwardly (arrows 29) and downwardly (arrows 30) through the member 15 and contact 17. Subsequently the contacts 20 are moved upwardly by the blast gas acting on a piston 21 in which the contacts 20 are carried. The opening of the contacts 20, 17 to form the isolating gap is delayed with respect to the opening of the contacts 12, 15 by the admission of gas through a port 27 to the rear of the piston 21, this gas being exhausted at a controlled rate through a needle valve 28. After, or coincident with, the interruption of the-current which flows through a resistor 16 on the opening of the interrupting contacts 12, 15, the isolating contact 17 is moved downwardly. On the formation of the isolating gap, the blast acting on the gap causes an upward blast component 32 to oppose the downward exhaust from the interrupting contacts 12, 15 to reduce the blast to those contacts, and a downward blast component 31 which exhausts through the contact 17. Specifications 666,834, 712,436, 723,156 and 733,434 are referred to.

Title: Improvements in or relating to apparatus including a member arranged to move repeatedly along a working path
Inventor: SCRUTON ARTHUR HERBERT
IPC: F16H27/04
Filed: 1958-09-03
Abstract: 859,029. Converting rotary into reciprocating motion. GENERAL ELECTRIC CO. Ltd. Aug. 28, 1959 [Sept. 3, 1958], No. 28316/58. Class 80 (1). [Also in Group XXIII] In apparatus in which an operating member moves repeatedly along a working path between fixed limits the member is driven by means rotating at substantially constant angular velocity and driving the operating member through a differential gear into which additional driving movements may be fed to control the timing of the operating member. The Figure shows a machine for cutting lengths from a glass tube 3 emerging from a drawing machine 4 driven by a motor M through gearing 12. The same motor drives the cutting machine through a differential gear comprising sun wheels 15, 16 and planet wheels 17 mounted in a casing 18 carrying two identical sets of sprocket teeth connected by chains 23, 24 to sprockets 25, 26. The shaft 9.1 driven from the differential gear reciprocates a carriage 1 on rails 2 by means of a chain 7 carrying a roller 10 engaged in a slot 11 in the carriage. The carriage supports a ring burner 6 surrounding the tube. The shaft 9.1 is also geared to a shaft 38 which performs. one revolution for each two reciprocations of the carriage. The sprockets 25, 26 may be coupled, through electromagnetic clutches 27, 28 to pinions 29, 30 engaged with a double rack 31. The differential casing 18 is held stationary during each forward stroke of the carriage 1 while the ring burner is advanced by the carriage at the same speed as the tube 3 which is heated by the burner either until it melts or to a lower temperature, after which it is chilled to crack it. If the differential casing is rotated during the return stroke of the carriage this can be retarded to control the point at which the burner engages the tube on the next forward stroke. On alternate return strokes cams 36, 37 operate valves 34, 35 to supply air to a cylinder 33 to operate a piston 32 which actuates the rack. Other cams 39, 40 control switches S1, S2 to energize the appropriate one of the clutches 27, 28 required to transmit movement, always in the same direction, from the rack to the differential casing 18. While the rack is stationary both clutches are energized to hold the casing stationary. The length of tubing severed at each stroke of the carriage 1 is determined by the stroke of the rack 31 as limited by adjustable stops, not shown. In another embodiment the rack 31 is driven by a cam driven from the shaft 9.1 through a bellcrank, the effective length of which is adjustable by moving a pivot along a slot by means of a screw, the setting of which determines the length of glass cut. In another embodiment the carriage 1 is driven by a cam instead of the chain of Fig. 1. Specifications 808,284 and 843,192 are referred to.

Title: Improvements in or relating to insulated resistance wire and methods of forming an insulating coating thereon
IPC: H01C1/032
Filed: 1930-09-22
Abstract: 366,004. Discharge apparatus. SIRIAN LAMP CO., 260, Sherman Avenue, Newark, New Jersey, U.S.A.-(Assignees of Ruben, S. ; 165, Storer Avenue, New Rochelle, New York, U.S.A.) Sept. 22, 1930. No. 28322. Convention date, Sept. 23, 1929. [Class 39 (i).] A resistance wire has a coating of material which is a good conductor of heat and does not become electrically conducting at high temperatures, the coating comprising an inner layer of a compound of boron, magnesium, aluminium, silicon, beryllium, or other metal having a low atomic number fused to the wire or filament, and an outer layer of another compound of a similar metal, which has a slight chemical action with the inner layer so as to bind the layers together. In an example, three parts by weight of beryllium aluminosilicate are mixed with one part of ammonium borate and made into a paste with water. This mixture is coated on a tungsten wire, which is then heated by passing a current through it in order to dry the coating. Two or more coats of the mixture may be applied. The outer coating material is prepared by grinding beryllium oxide with 25 per cent by weight of ammonium borate and a little distilled water. The mixture is applied to the coated wire and the temperature raised to 500‹ C. at which temperature the ammonium borate decomposes forming ammonia, water vapour, and boric oxide. Five or more coatings are applied. The wire thus coated may be bent and welded into position in a vacuum tube &c. If it is not to be used at once, the wire should be coated with collodion to prevent absorption of water. When placed in a vacuum tube, the resistance is raised to a temperature of about 2000‹ C. during exhaustion, at which temperature the beryllium aluminosilicate fuses to form a dense flexible coating integral with the wire. The beryllium oxide forming the outer layer withstands temperatures of 2400‹ C. without fusion. Aluminium oxide up to a limit of 75 per cent by weight may be mixed with the beryllium oxide to form the outer layer. The Specification as open to inspection under Sect. 91 (3) (a) states also that the inner layer may comprise a mixture of beryllium aluminosilicate and sodium silicate, the outer layer comprising a mixture of beryllium oxide and sodium silicate. This subject-matter does not appear in the Specification as accepted.

Abstract: 874,886. Nuclear reactors. COMMISSARIAT A L'ENERGIE ATOMIQUE. Aug. 19, 1959 [Aug. 21, 1958], No. 28346/59. Class 39(4). A graphite moderator structure is formed of columns of superimposed blocks 1 having a central duct 2 for the passage of fuel elements and coolant. The horizontal abutting surfaces of each block are formed with a pair of troughs 6 and four notches 4, the notches receiving keys 3 and the troughs receiving struts 5, the enlarged ends 7 of which abut the key faces, whereby the keys end struts serve to position the blocks of a column relatively to one another and also to the blocks of adjacent columns. Fig. 1 shows the adjacent ends of two blocks 1. The keys and struts may be formed of graphite or beryl. In a modification (not shown) the blocks 1 are hexagonal in cross-section and the struts 5 have a triangular cross-section. Control rod ducts may be formed at the junction of four columns, Fig. 3, and a beryllium sleeve 8 inserted at each level of the struts, the latter being made shorter to bear against the sleeve. Specifications 784,291, 784,292 and 785,876 are referred' to.

Abstract: 486,643. Prepayment mechanism for meters. LANDIS & GYR AKT.-GES. Oct. 19, 1937, No. 28426. Convention date, Feb. 19. Addition to 480,552. [Class 27] Coin action, thrust, with delivery proportionate to value of coin.-The invention described in the parent Specification is modified by forming the operating members as toothed segments which are axially movable, for selective engagement with the pinion connected with the quantity mechanism, under the control of an apertured disc actuated by the slide in the coin pocket. As shown, a coin inserted into a diametral pocket in a rotatable drum 18 thrusts back a slide 20 having a pin 86 which turns a disc 88 loose on the shaft of the drum against the action of a spring 89. Secured to the drum are a pair of spaced parallel plates 98 and 100 carrying a series of four axially slidable rods 101, 102, 103, and 104 biassed towards the disc 88 by springs 114, but normally held back by engagement of projections 112 with a fixed segmental guide 116a. Each rod carries a toothed segment 106, 107, 108, 109, having one, six, twelve and twelve teeth respectively, adapted to drive a pinion 36 connected with the quantity mechanism but normally lying out of the plane of such pinion. The disc 88 is provided with holes 90 and 91 and peripheral slots 92, 93, 94, 95, 96 and 97 adapted to be brought into selective register with the rods according to the coin inserted. In the case of a penny, the disc 88 is turned to a position in which aperture 92 registers with rod 101 so that, when the drum 18 is rotated through bevel gearing 5, 17 from a hand shaft 2, and the rods clear the guide 116a, pin 102, and that pin only, passes through the disc 88 and its one-tooth segment 106 rotates the pinion 36 by an amount appropriate to a penny. Similarly, in the case of a sixpence or a shilling, the hole 90 or aperture 95 is brought into register with rod 102 or 104 respectively, so that the pinion 36 is rotated by the six-tooth segment 107 or twelve-tooth segment 109. With a twoshilling piece the pinion 36 is rotated by the two twelve-tooth segments 108 and 109 in succession, and with a half-crown by the six-tooth segment 107 in addition.

Abstract: 386,930. Microscopes. LEITZ GES., E., Optical Works, Wetzlar, Germany. Oct. 15, 1932, No. 28799. Convention date, Jan. 29. [Class 97 (i).] In an opaque illuminator, particularly for use in investigating doubly-refracting media in polarized light, the reflecting element of the illuminator is arranged to provide metallic reflection in combination with two refractions at a relatively great angle of incidence. It is stated that such a reflector produces the minimum alteration in the condition of polarization of the incident light. In the preferred form the reflector is a glass plate G having a wedge form to prevent disturbance by " ghosts " caused by reflection at the front surface G<1>, and having a metallically coated rear surface G<2>. An incident ray H undergoes refraction at the surface G<1>, then reflection at the surface G<2>, and then a second refraction at the surface G<1>, emerging in the direction H<1>. The angle of the wedge is at least 1‹ and at most such that the angle between H and H<1> is approximately 90‹.

Abstract: 934,361. Control of motors; protective cut-out arrangements. UNITED STATES STEEL CORPORATION. Aug. 19, 1960 [Sept. 4, 1959], No. 28849/60. Classes 38 (3) and 38 (5). The driving motors 18, 20, 22, 24, 26 of a continuous strip electrolytic tinning line are caused to slow down if the generator 42 for the electrolytic bath is overloaded, and if the overload persists both the motors and the generator are stopped. The generator circuit includes a current sensing device 54 by which relay contacts 56C are closed on overload. This results, through relays 58 and 60, in the operation of a controller 40 which selects a lower of three speeds for the driving motors by inserting resistors A or B in their supply circuit, which, it is said, frequently removes the overload. At the same time, the supply to the energizing coil 64 of a time delay relay 62 is broken by contacts 58C1 ; the relay is then held on by the discharge of a capacitor 66 through a variable resistor 68. The capacitor may also be variable. If the overload persists after the capacitor is discharged the relay is released to close contacts 64C1 and 64C, stopping the main and generator drive motors, respectively.
