Title: Improvements in rubber compounds or products and method of making the same
IPC: C08L7/00
Filed: 1938-01-21
Abstract: 513,939. Indiarubber compositions. STEIN, J. Jan. 21, 1938, No. 2101. [A Specification was laid open to inspection under Sect. 91 of the Acts, July 22, 1938.] [Class 70] Indiarubber compositions having antiseptic or therapeutic properties in contact with body emissions are prepared by incorporating before or after vulcanization an antiseptic material. If incorporated before vulcanization, a compound such as a salt or ester which is unacted upon by the vulcanizing ingredients may be used and the antiseptic subsequently liberated by the action of ammonia. Vulcanization is effected with sulphur chloride at a temperature of about 43 ‹C. Antiseptics which may be used are antiseptic nitrogen ring compounds and amines, substances having phenolic hydroxy groups, organo-metallic compounds, inorganic metallic compounds and, in particular, acriflavine, rivanol, oxazines, isoquinoline, 6-ethyl- 8 oxyquinoline, thiazines, phenol and carbethoxy derivatives, catechol, thymol, cresophan, pchlor-m-xylenol, phenyl mercuric nitrate or acetate, tolyl mercuric hydroxide, anilie mercuric hydroxide, organic salts of tin or bismuth, halogenated aromatic acids such as chlorbenzoic acid or chlorsalicylic acid, chlorinated benzenes, salicylic or benzoic acids, phenolic esters, metallic salts of phenols, chaulmoogra oil, and stannous or stannic hydroxide or chloride. The antiseptic substance may be formed in situ, e.g. aniline may be masticated into rubber and on vulcanization an antiseptic substance is formed by reaction of the aniline on the vulcanizing agent. A basic antiseptic such as oxyquinoline and an acid such as boric acid may be masticated together into rubber. The Specification as open to inspection under Sect. 91 comprises also the subject-matter of Specification 514,598, and the formation of compounds in which the antiseptic is united to the rubber through an ether linkage, formed by treating rubber with monothiohydroquinone hydrohalide or substituted derivatives or heterocylic ring compounds having a thiohalide group. Mercaptans and polythio compounds may be incorporated and the compound formed during vulcanization with sulphur chloride. This subject-matter does not appear in the Specification as accepted.

Abstract: 347,187. Turbines. GUY, H. L., Thornhill, Hale Road, Hale, Cheshire, and ASSOCIATED ELECTRICAL INDUSTRIES, Ltd., Bush House, Aldwych, London. Jan. 21, 1930, No. 2104. [Class 110 (iii).] In turbine plant which includes a steam accumulator the turbine has a number of tapping points at different pressure stages for connection to the accumulator. Boilers 1 supply main steam to the turbine 2 which is tapped at 6, 7, 8 and has valved connections with storage vessels 13 .. 16. Non-return valves 19, 20 at the inlets and outlets of the battery are provided as well as stop valves 17, 18.

When all the valves 17, 18 are open steam passes to or from the accumulator vessels according to the pressure conditions when the valves 9, 10, 11 are open. Instead of manual operation of the valves, automatic actuation by means responsive to the pressures may be adopted.

Abstract: 1,066,639. Resilient mountings. LORD CORPORATION. Jan. 17, 1966 [March 2, 1965], No. 2183/66. Heading F2S. In a resilient mounting comprising a body 4 of elastomer which is dropped into and not bonded to a socket 2, 3 in a supporting member 1 and which has a central fixing tube 9 which, with a skirt portion 15 of the body, projects at its lower end through an opening 3a in the bottom wall 3 of the socket 2, 3 a metal ring 7 is bonded into the lower end of the body 4 to seat upon the lower wall 3 of the socket around the opening 3a so that, under heavy loads, Fig. 3 (not shown), the elastomer body 4 is prevented from extruding through the central opening 3a. The body 4 has a head 6 which overlaps the upper surface 6a of the supporting member 1 around the socket and which becomes progressively compressed by a supported member 11 as the load is increased. The supporting member 11 and a washer 13 are clamped to the tube 9 by means of a bolt 10 and a nut, the skirt 15 being clamped between the lower surface 16 of the supporting member 1 and the washer 13 to cushion rebound forces. In a modification, Fig. 5 (not shown), a separate body (33) acts as a rebound cushion.

Title: Bubble domain memory system
IPC: G11C29/00
Filed: 1973-01-16
Abstract: 1371597 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 16 Jan 1973 [1 May 1972] 2207/73 Heading H3B [Also in Division G4] In a cylindrical magnetic domain storage system, a plurality of operational storage units 1, 2 ... N, Fig. 1, and a spare storage unit are provided on a single magnetic sheet 10, the spare unit being arranged to replace a faulty operational unit detected during manufacture or operation. Each storage unit is basically the same as the unit 1 shown except for the internal organization of its write decoder WD. The system is controlled from a control circuit 16 which operates a bias field source 14 and a domain propagation field source 12, as well as controlling common operational circuitry for the units comprising a write driver 18, a decode driver 20, a sense current source 22 and a clear current source 24. Operation of the write driver causes a domain generator G1 to pass a domain to the write decoder WD1 in each of the units. The write decoders of the storage units 1, 2 ... N each consist of two path selectors SW, Fig. 2, controlled by the direction of currents I DA , I DB  from the decode driver, the path selectors being arranged so that only a selected one of a group of four decoders can pass a domain to a storage propagation path 28 at any time, while the remaining decoders pass respective domains to domain annihilators A1a-A4a. Domains in path 28 pass to a read decoder RD where they are either returned to path 28 for recirculation or pass through an, e.g. magneto-resistive, sensor S to a clear means CL. A further operational choice at the clear means either recirculates the domains by way of path 38 or extends them to an annihilator A1b. The write decoder of the space storage unit differs in that it comprises four path selectors SW arranged so that domains from generator GS normally pass directly to annihilator ASa. By selectively opening switches SA1 or SA2 and SB1 or SB2, which may be transistors or fusible links, the spare storage unit may be matched to the character of any of the operational storage units it is required to replace. Details of the path selectors are shown in Fig. 3 (for type SW1) and Fig. 4 (for type SW2). In Fig. 3 a downward current I DA  in strip 42, or the absence of current, causes a domain BD to pass along upper path 46, while an upward current diverts the domain to lower path 48. In Fig. 4 only a downward current will divert a domain to the lower path 52. Domain propagation is by the combination of a rotating in-plane field H and permalloy overlay T and I bars 40, 50. A test system is shown in Fig. 7 in which the various storage units are automatically monitored by test equipment 60. If a fault is detected in a unit the equipment selectively operates switch controls A and B which selectively open a switch in each of the groups SA1, SA2 and SB1, SB2, Fig. 2, to bring the spare storage unit into use.

Abstract: 1495823 Protecting converters GENERAL ELECTRIC CO 22 Jan 1975 [21 Feb 1974] 2757/75 Heading H2F In or for a converter circuit comprising a highpowered thyristor, a protective circuit comprises at least two PNPN voltage sensing elements 27 connected in series with storage means 24, voltage distributing resistors 36, 37 being connected across the voltage sensing elements and the junction of the elements 27, 24 being connected to a terminal for the gate of the highpower thyristor being protected. The resistors 36, 37 are selected so that the sum of the breakdown values of the PNPN elements 27, exceeds the threshold voltage at which the thyristor is to be triggered. As described, the voltage sensing elements 27 are thyristors 27 having their gates connected to cathodes and protect the main thyristor (not shown) against overvoltage in the forward direction by turning on the main thyristor on its gate. The diodes 28 ensure that the thyristors 27 have a reverse blocking voltage exceeding that of the main thyristor. A capacitor 35 arranges an effective reduction in the breakdown voltage as a function of the rate of rise thereof. Alternatively, capacitor 35 may be replaced by a capacitor connected between the anode and gate of one of the thyristors 27. The invention is applicable to a HVDC converter comprising a series arrangement of a plurality of main thyristors each having its over-voltage protection as shown in Fig. 2, the series arrangement being bridged by a lightning arrester.
