Title: Polyurethane foam
IPC: C08J9/32
Filed: 1976-04-29
Abstract: 1528288 Flame retardant polyurethane foams DOW CORNING CORP 29 April 1976 [18 Sept 1975 1 March 1976] 17468/76 Heading C3R A flame retardant rigid polyurethane syntactic foam is obtained by curing a mixture comprising a polyol; a polyisocyanate; microballoons; a catalyst and a flame retardant having a viscosity of less than 100 centipoises at 24‹ C. and a volatility such that it is not evaporated by the heat of reaction generated when the ingredients react, the flame retardant also acting as a flow promoter for the mixture, there being present in the mixture a sufficient amount of microballoons to provide a non-castable mixture in the absence of the flame retardant and a sufficient amount of flame retardant to provide a fluid, castable mixture. Suitable polyols and polyisocyanates are those which are liquid at 25‹C. In a typical example a polyol; polymethylene polyphenyl diisocyanate; a flame retardant, tris- (beta-chloroethyl)-phosphate; glass micro-balloons and a catalyst comprising triethylene diamine in dipropylene glycol were mixed adding the isocyanate last. The resulting fluid mixture was cast into a mould and cured to give a rigid flame retardant foam. Glass fibres, less than 25 mm. in length, may be added to the mixture to improve the flexural strength of the foam.

Title: Improvements in or relating to arrangements for distinguishing between two radiations
IPC: G01T1/208
Filed: 1962-05-07
Abstract: 932,536. Nuclear particle discriminators. PHILIPS' GLOEILAMPENFABRIEKEN N.V. May 7, 1962 [May 10, 1961], No. 17480/62. Class 40 (3). An arrangement for discriminating between the arrival of neutrons and gamma radiation comprises a scintillation crystal 1 and photomultiplier 2. A proportion of the output from dynode 4 is applied to a long-time-constant circuit which effects integration to give . an output from a single scintillation as indicated at 16. The output from dynode 5 is fed to a damped oscillatory circuit to give a waveform such as indicated at 17. With gamma radiation the pulse 16 is considerably shorter than is the case with neutron detection and the constants of the oscillatory circuit are arranged to be such that when the waveforms 16 and 17 are added in the amplifier 19 there is no negative-going part of the resultant in the case of neutrons but there is such a part in the case of gamma radiation. This distinction is used to separate pulses due to the different kinds of radiation; for example, a detector circuit 20, 21, low-pass filter, and amplitude discriminator 27 enables neutron pulses to be separated out and used to control a gate circuit in the output line from photo-multiplier 2. The device may also be used for distinguishing α-partioles from protons or α-particles from deuterons. Specification 823,263 is referred to.

Abstract: 502,667. Type-bar-making machines. CLEMO, F. A. (Mergenthaler Linotype Co.) June 24, 1937, No. 17585. [A Specification was laid open to inspection under Sect. 91 of the Acts, March 19, 1938.] [Class 100 (iii)] Quadding-apparatus.-Means for effecting a fixed or uniform indenture of the lines, such as is necessary for straight-line margin work, comprises a banking-pawl adapted to be engaged during justification of the line by one or another of a series of stops or teeth on the vice-jaw, and continuously adjustable screwoperated means for effecting a fine adjustment of the jaw in increments of a quarter-point. The jaw A. Fig. 7, which is adapted for quadding- movement, has extending from it a bar A<2>, which is secured to the jawsupporting block A<1>, Fig. 6, and is formed with a series of stops or teeth A<4> spaced at, say, three-em intervals. Above the bar is a banking-pawl E having a depending nose-portion E<1>, which is adapted to engage the teeth A<4>. The pawl normally stands out of the plane of the teeth, but is moved into their plane after the jaw has closed on the line, so as to arrest the jaw during justification. The pawl E is 'secured to a block E<2>, which is mounted on a rockshaft F capable of limited endwise movement in its bearings. The block is adjustable along the shaft to enable the position of the pawl to be varied in steps of half an em, and is held in adjusted position by a vertically movable plunger E<7>, which engages annular grooves F<5> in the shaft, and can be released therefrom by means of a push-button E<11>. A finer adjustment of the pawl, in steps of a quarter-point, is obtained by endwise movement of the rock-shaft F, which is effected by rotation of a threaded bushing G<1>, in which the shaft is journalled, by means of a knob J. The pawl is normally held out of engagement with the teeth A<4> by a spring K<3>, Fig. 2, which acts on a slide K having depending fingers K<4>, which embrace the pawl. Before the line is justified, the pawl is moved into the path of the teeth by' the forward movement of the mould-disc B, which acts on the slide K through a second spring-pressed slide K<1>. After the casting, the pawl is positively rocked rearwards, to disengage it from the teeth A<7>, by the rearward movement of the mould-disc, which acts through an L-shaped arm K<7>, pivpted to the slide K<1>. The arm K<7> is normally held by a spring in raised position clear of the mould-disc, and is depressed, so as to engage behind the disc, by an arm C' on the metal-pot C during its advance.

Title: Improvements in or relating to dynamo-electric systems for the transmission of mechanical power
IPC: H02K51/00
Filed: 1944-09-18
Abstract: 612,811. Transmitting mechanical power. BOWES, T. D. Sept. 18, 1944, No. 17812. Convention date, Dec. 3, 1943. [Class 38 (iv)] In an arrangement wherein a rotor 1 drives a shaft 8 at a reduced forward speed or in the reverse direction, a part of the energy of the rotor 1 is transmitted magnetically to a driven member 27 which is fixed to the second shaft 8, the remainder of the energy being converted into electricity and transmitted to the driven member to control its speed and rotation. The rotor, carrying four D.C. poles 11, is mechanically free from, but coupled to, the driven member 27 by a magnetic flux which is insufficient to prevent relative rotation between the members. This slip results in the cutting of the lines of force and causes a current to be generated in three-phase generator windings 29 on the member 27. The speed difference be. tween the elements 1 and 27 is preferably kept greater than the desired speed of the member 27, and the energy transmitted electrically is generally greater than that applied magnetically. The voltage generated in windings 29 is applied to three-phase windings 35 also on the member 27, and this current reacts with squirrel-cage bars 45, 46 in the stator 48 to rotate the member 27 as a motor, the speed of which is determined by the number of poles induced by the windings. The member 27 may be reversed by reversing the connections of two phases of the motor winding. A modification (not shown) is described in which an auxiliary three-phase current is supplied to the winding 29, the member 27 being held stationary until the rotor 1 is caused to rotate and start up a prime mover, the apparatus then operating as described above.

Title: A cyclic process for the removal of oxides of sulphur from waste gases
IPC: B01D53/50
Filed: 1935-06-26
Abstract: Sulphur oxides are removed from waste gases, particularly furnace gases by contacting with a suspension and/or solution of magnesia in water to form magnesium sulphate together with some sulphite, this product being treated to recover the magnesia for re-use and the sulphur.  The gases, cooled to a temperature, of about 110--140 DEG C., are treated as by scrubbing or spraying but preferably by passage through or over stationary or slowly moving screens of absorbent material such as woven cotton moistened by dipping into or spraying with the magnesia-containing liquid.  The sulphate and sulphite formed may be separated by crystallization, heated to remove water of crystallization, ground with about 25 per cent of its dry weight of coke or charcoal and heated, for example to 700 DEG  C., in an atmosphere containing hydrogen, e.g. water gas.  Sulphuretted hydrogen together with hydrogen and sulphur are liberated, while magnesia admixed with carbon in condition suitable for suspending in water for re-use remains. The hydrogen sulphide may be converted to sulphur by passing the evolved gases through a solution of magnesium bisulphite containing free SO2 made by passing SO2 into a suspension of magnesia or magnesium carbonate.  Sulphur is precipitated and small amounts of polythionic acids and their magnesium salts remain in solution.  By maintaining only a small excess of SO2 during the washing, by introducing it continuously or periodically, complete decomposition occurs and traces of SO2 carried over are removed by a suspension of magnesia.

Abstract: 255,884. I. G. Farbenindustrie Akt.- Ges.,. (Assignees of Farbwerke vorm. Meister, Lucius, & Br³ning). July 22, 1925, [Convention date]. Catalytic agents, preparation and treatment of; hydrogenated organic compounds, catalytic production of.-Catalysts comprising nickel admixed or not with a metal of the iron or silver group are prepared by precipitating the nickel &c. as a crystalline hydroxide or carbonate in presence of a carrier, and then reducing the product with hydrogen at a temperature of 400‹ C. or above. To precipitate the hydroxide or carbonate in crystalline form, precipitation is effected slowly and at raised temperatures, suitable precipitants being alkali carbonates or, when ammonia compounds of nickel &c. are used, air containing carbon dioxide. The catalysts are suitable for use in hydrogenating processes, and in this connection reference is made to the production of isopropyl alcohol, ethylamine, and piperidine from acetone, acetonitrile, and pyridine respectively. According to one example, mixture of ammoniacal nickel nitrate solution and silicic acid gel is heated to 70‹ C. and treated with a strong current of air. The precipitate obtained after about 4 hours is filtered, washed, and dried, and is then treated with hydrogen at a temperature of 100- 130‹ C. which is gradually raised during 5 or 6 hours to 415-420‹ C. When reduction is complete the product is quickly cooled in presence of hydrogen and is poured into a suitable suspending agent such as water or pyridine. According to another example, a mixture of nickel nitrate solution and silicic acid gel is heated to 70‹ C. and treated with sodium carbonate solution added drop by drop over a period of 8 hours, and accord. ing to a further example a mixture of a solution of nickel, cobalt, and copper nitrates and silicic acid gel is similarly treated. In each case the product is further treated as described above.
