Title: Improvements in or relating to bituminous thermoplastic printing inks
IPC: C09D11/12
Filed: 1939-11-24
Abstract: 536,626. Ink. INTERCHEMICAL CORPORATION. Nov. 24, 1939. No. 30769. Convention date, Dec. 8, 1938. [Class 146 (iii)] A thermo-plastic printing ink having a melting point of between 150 and 300‹F. has a vehicle composed of at least 50 per cent. by weight of a solvent wax (i.e., a resin-free animal, vegetable or mineral wax, or synthetic waxy material such as a high molecular weight alcohol or ester or a fully hydrogenerated oil or oil acid) and between 5 and 50 per cent. of a bitumen. The bitumen is preferably that known under the Registered Trade Mark " Gilsonite mixed with a bitumen having solvent action thereon, e.g. coal tar pitch, montan pitch, or petroleum pitch. The solvent wax is hydrogenated soya bean or fish oil, and montan wax may also be added. The "Gilsonite" acts as a colouring material, but other pigments preferably ground in lithographic varnish may be added. Specification 536,968 is referred to.

Title: Improvements in or relating to controlling apparatus for automatically stopping internal combustion engines or actuating a signal device therefor
IPC: F02B77/08
Filed: 1952-12-04
Abstract: 729,951. Emergency alarms. PERKINS, Ltd., F., and GIL, J. V. Nov. 10, 1953 [Dec. 4, 1952], No. 30807/52. Class 7(2). [Also in Groups XXVI and XXXVII] An alarm for an internalcombustion engine comprises a switch wherein one of the contacts is formed by a column of mercury disposed in a chamber connected with the engine induction manifold so that a fall in manifold pressure corresponding to a rise in engine speed above a predetermined value causes the column of mercury to close the switch and actuate the alarm. The switch comprises a metal body 1 having a sealed chamber 2 therein, formed by a recess closed by a cover 3 on which are mounted in air-tight manner, a connector 4 leading to the engine induction manifold and an adjustable rod contact 5, extending through a tubular insulator 6, and having a tapered end 12 projecting into the end of a tube 7 depending from the chamber 2 in a plugged bore 8, which is of larger diameter than the external diameter of the tube 7 and is vented to the atmosphere at 10. The tube 7 and the space 8 around it contain mercury such that, when the engine is at rest, the mercury is about ¥ in. from the top of the tube 7. When the engine is rtmning normally the depression in the chamber 2 due to the vacuum in the engine manifold causes the mercury to rise in the tube 7 but to be still clear of the contact 5. If the engine overspeeds, however, the mercury rises sufficiently to contact the rod 5 and close the switch to operate the alarm. In a modification a non-return ball valve is fitted in the connector 4 from the sealed chamber to the engine manifold to prevent mercury being drawn therein.

In order to compensate for the voltage drop in an alternator owing to the load, the excitation winding 3 is arranged to be fed from rectifiers R from the stator A through a potential transformer T1 and a current transformer T2 acting as a voltage regulating device. The transformer T2 has a primary S3 and a secondary S1 on a separate core N1, the relative position of one core with respect to the other core being adjustable. The two secondaries S1, S2 are so wound and arranged so as to act in the same or opposite sense as required to provide a compensating voltage for excitation under load conditions. A variable resistance Rh in series with the exciting winding 3 adjusts the voltage applied to the latter to a convenient value. As the two secondaries S1, S2 respectively supply the wattful component and wattless components of the current according to the P.F. ' of the load, a self-regulating arrangement is provided according to the magnitude of the load and of its P.F. The invention is also applicable to polyphase alternators and to alternators working in parallel. In the latter case, reactors are provided between the alternators to suppress circulating current.

Title: Polymerization of propylene oxide
IPC: C08G65/10
Filed: 1957-10-09
Abstract: Polypropylene oxide having a molecular weight of at least 1000 and preferably up to 10,000 and of which 40-80% of the molecular chains have terminal propenyl or allyl ether groups is obtained by reacting liquid propylene oxide in presence of essentially dry pure potassium hydraoxide at temperatures from 0-40 DEG C. and separating the polymer from unpolymerized propylene oxide and catalyst.  Preferably the potassium hydroxide is a finely divided powder.  0,5-20% catalyst per weight of propylene oxide is employed and the catalyst and propylene oxide are mixed and maintained under agitation during the reaction; a continuous process with recyclisation of unpolymerized monomer may be employed The catalyst is separated by dissolving the reaction products in ethyl ether, ethyl alcohol, or benzene filtering and evaporating to free the polymer from solvent, or the catalyst may be removed by masticating with water in a wash mill.  Unreacted monomer may be stripped off in vacuo.  In an example 250 gs propylene oxide which has been dried over KOH pellets and distilled through a fractionating column is mixed in a flask with 16,7 gs. dry powdered KOH and the mixture stirred at 33 DEG C.  The products were neutralised by contact with a cation exchange resin and the ether solution filtered.  Tests showed a 46% conversion in 21 hours and 88,4% in 57,5 hours.  Infra-red hydroxyl and bromine analysis indicate 2,93 X 10-4 mols OH/g of polymer and 1,98 X 10-4 of unsaturation per gram polymer.  The terminal unsaturation in the polymer chains permits conversion to epoxide, chlorhydrin, glycol or mecaptan addition products which may be used as starting materials for resins or elastomers or for lubrication purposes.

Abstract: 862,838. Rendering bricks impermeable to gases. GAS COUNCIL. Jan. 17, 1958 [Oct. 19, 1956], No. 31964/56. Class 56. Refractory bricks or brickwork are rendered impermeable to gases at high temperatures by applying a vitrifiable glazing composition to the working face of the brick or brickwork and heating to form a glaze, a layer of finely divided refractory material containing at least 90% by weight of alumina being applied either to the brick before the glaze, or to the glaze while hot and viscous. An initial layer of refractory material may be applied to the brick or brickwork before glazing and another layer to the glaze. The refractory material may be applied to the surface in the form of an aqueous slurry or applied to the viscous glaze by air entrainment. The glazing composition employed when the brickwork is treated in situ is preferably such that the glaze vitrifies at the highest temperature reached in the structure or one whose vitrification temperature is higher than the highest temperature reached in the structure, vitrification being effected by the application of additional heat e.g. by traversing the hot surface by an oxy-coal gas flame in which case the finely-divided refractory material may be entrained in the oxygen supply to the flame. The process may be applied particularly to silica bricks or brickwork, the treatment being carried out in situ. A specified glazing composition contains oxides of the following elements (the figures being oxide percentages by weight) Si 46À5, Al 13À9, Ca 7À2, Mg 6À4, S 17À9, Na 8À1.
