Title: Process for the preparation of reaction products of polybutadiene and sulphur dioxide and the products so produced
IPC: D01F6/24
Filed: 1950-02-24
Abstract: The reaction of polybutadiene with sulphur dioxide, in which a solution of polybutadiene activated by a hydroperoxide or by another oxygen-yielding substance in combination with an ether, is extruded into a sulphur dioxide solution to form threads, fibres, tapes or films, is characterized by using polybutadiene obtained by emulsion polymerization.  The polymerization temperature is preferably not above 25 DEG  C.  The products are stated to be mechanically and chemically more stable than those obtained from sodium polybutadiene, and the stability is independent of the sulphur content.  The sulphur content also is independent, within wide limits, of the sulphur dioxide concentration, which is preferably 60-200 gms./litre, and of the temperature, which may be between 12 DEG  and 30 DEG  C. Comparisons are given of tensile strengths, stability, elongation, &c.  Plasticized rubber or unsaturated, low molecular weight compounds such as 1,5-hexadiene, allyl alcohol or diallyl phthalate, may be present in the polymer solution.  Specifications 611,919, 616,276 and 666,640 are referred to.ALSO:The reaction of polybutadiene with sulphurdioxide, in which a solution of polybutadiene activated by a hydroperoxide or by another oxygen-yielding substance in combination with an ether, is extruded into a sulphur dioxide solution to form threads, fibres, tapes or films, is characterised by using polybutadiene obtained by emulsion polymerisation.

Title: Improvements in or relating to the Manufacture of Steel.
Inventor: HADFIELD ROBERT ABBOTT
IPC: C21C7/06
Filed: 1917-04-10
Abstract: 127,302. Hadfield, Sir R. A. April 10, 1917. Cast-iron and scrap processes; annealing. - Steel containing from about 0.3 to 1 per cent or more of carbon and practically free from or low in manganese, is obtained by refining molten metal and then deoxidizing it by means of silicon, aluminium, or silicon and aluminium, or substances consisting mainly of these elements. The desired percentage of carbon is obtained by adding a carburizing agent of good quality, such as, for example, pig iron of good quality or anthracite. The molten metal to be refined may be obtained from steel turning and scrap, or from ordinary hematite, steel turnings and scrap, and pig iron, and the refining may be effected in openhearth, bessemer or electric furnaces in order completely to decarburize, desiliconize, and demanganize the metal. A high-grade steel may be pro. duced by treating the molten metal by the openhearth, bessemer or like process, and afterwards by the electric process to obtain a metal very low in carbon silicon, sulphur, phosphorus, manganese, and other impurities, the refined metal being then deoxidized and recarburized. The steel obtained may be heated to about 850‹ C., then quenched in water, afterwards reheated to about 615‹ C., and cooled slowly in air. This heat treatment is particularly intended to improve the qualities of the medium carbon steels.

The cartridge is supplied with inner container located 90‹ anticlockwise from the position shown; thus lip 54 is lodged against ledge 60 and protruberance 51 with corners 57, 58, is adjacent tongue 44. The cartridge is located above hopper 19 by cooperation of grooves 40, 41, 39 with ridges 25, 26, 27 respectively, and means outside the cartridge co-act with tongues 64, 65, 66 located in sockets 70, 71, 72, to rotate the inner container clockwise to the position shown, resilience of the two containers allowing 51 to pass under 44, 54 and 55 to pass over surface 45. Once the inner container is in the position shown, protruberances 51, 54, 55 and co-acting tongues 43-46 render it incapable of further rotation; the cartridge thus cannot be re-used. A circuit is described which renders the copier incapable of operation unless a cartridge is in position and has been rotated to the position shown.

Abstract: 929,684. Washing-machines. CLAMAR S.A. Feb. 13, 1961 [Oct. 4, 1960], No. 5213/61. Addition to 912,439. Class 138 (2). [Also in Group XXIV] A driving device for a washing-machine in which the drum is automatically alternately rotated in opposite directions comprises two coaxial gear-wheels 6, 20 driven in opposite directions, between which is disposed a slidable collar 15 which can be connected through dogclutches to either of the wheels 6, 20, the collar 15 sliding on a key 32 on a sleeve 17, which is mounted loose on a driving-shaft 1, the sleeve 17 driving a sleeve 25 through a dog clutch 24, 36 to rotate the drum (not shown). As the driving-shaft 1 rotates a pinion 2 mounted thereon causes rotation of a gear-wheel and pinion 3, 4 mounted on a shaft 5. The pinion 4 meshes with the gear-wheel 6 and rotates it in the same direction as the shaft 1 but at reduced speed. The pinion 4 also engages with a pinion 4a which serves to rotate the gear-whesl 20 in the opposite direction to the shaft 1. The gears 6, 20 are fitted with dogs 31, 30, respectively, which engage with dogs 16 on the collar 15. As the collar 15 is moved alternately between the position shown in Fig. 1 and a position where it is driven by the wheel 20 it is alternately rotated in opposite directions. The movement of the collar 15 is effected by a fork 35 fitted with prongs 34 which engage in a groove 33 in the collar, the fork 35 being oscillated about a pivot 28 by a crank on the shaft of a gear-wheel 9. The gear-wheel 9 is rotated by the shaft 1 through gears 7, 8 and a worm 10. The sleeve 25 carries a pulley and a belt 37 to drive the drum of the machine, and is slidable on the shaft 1 so that it can engage directly with the shaft 1 by means of a clutch 40 to drive the drum at a higher speed in one direction only, the movement of the sleeve 25 being effected by manual rotation of a crank 22 acting on a fork 21 pivoted at 29.

Title: Improvements in the manufacture of compounded hydrocarbon lubricating oils and greases
Filed: 1935-02-19
Abstract: A lubricant consists of mineral lubricating-oil in which rubber latex is stabilized by soft soap.  It may be thickened by adding paraffin wax or tallow; other oils or greases may be added to adjust the viscosity.  In an example, 1 gallon of oil, 0,25 gallon of rubber latex of 50 per cent rubber content, and 4 oz. of a potash-oleic acid soap are mixed by air blowing at 75 DEG  F. for 1 hr.  To each gallon of mixture there is added 0,25 lb. of paraffin wax or 0,25--4,0 lb. of tallow.  When the latex contains ammonia or other saponifying-agent the percentage of soap added is reduced.
