Abstract: 879,525. Wheel tyres. BUGDEN, H. June 3, 1960 [June 4, 1959], No. 19163/59. Class 144 (2). A wheel tyre comprises a resilient metal closed annular tube 10 which is embedded in a rubber covering providing a tread 15 sidewalls 16 and an inner peripheral layer 17, the covering being bonded to the tube 10 and to an inner peripheral mounting ring 11. The tube 10 may be pressurized with air through a conventional inflation valve 21 secured thereto and extending through apertures in the rubber wall 17 and ring 11. The ring 11 may have a radial web 13 which is apertured at 14 for attachment to a wheel, and the rubber tread 15 may comprise transverse grooves 23. Manufacture of the tyre may comprise welding the tube 10 from four channel-section semi-circular sections, and then positioning the tube 10 and ring 11 in a mould. The remaining spaces of the mould are then filled with the covering composition and the assembly cured under heat and pressure.

May 18, 1962 [May 19, 1961 ; April 19, 1962 ; April 20, 1962], No. 19264/62. Headings B1D, B1F and B2P. A cyclone for the separation of two phases in which the light phase is preponderant comprises an inlet 34, Fig. 2, for introducing dispersion at a flow velocity corresponding to a Reynolds number of less than 7,000. The heavy phase follows the path f, to the bottom chamber 33 through the opening 35 which is designed to reduce the rotational motion to zero. The heavy phase droplets entrained in the light phase (direction f 2 ) follow paths f 3 , f 4  (after passage through a packing 40) and f 5  and fall to the bottom chamber while the light phase passes out at 44. The flow of heavy phase from chamber 33 to the outlet is controlled by float valve 49 which is responsive to the delivery rate. Light settled phase from chamber 33 flows upwards in direction f 7 . In Fig. 3 (not shown) the heavy phase preponderates and the control valve is located at the top of the cyclone. Mixed phases are injected into the chamber 101, Fig. 4, and under the influence of the increase in cross-sectional area the heavy phase droplets 106 increase in size and recycle before discharge through the outlet 110. A plant for countercurrent contacting of liquid phases, Fig. 1, has a number of cascade stages which comprise ejector nozzles 2, 11 and 17, coalescing tubes 5, Fig. 4, and separators 6, 15a and 13, Fig. 2, which are fitted with automatic means for regulating the outflow rates of the fluids.

Abstract: 761,552. Internal shoe-drum brakes. MINISTER OF SUPPLY, REDMAYNE, L., and DAVIS, J. W. July 14, 1954 [July 14, 1953], No. 19478/53. Class 103 (1). In an internal shoe-drum brake for vehicles, a sealing means is interposed between a rotary brake drum and a stationary back plate; the sealing ring being carried by one of the members and resiliently urged into face to face engagement with a flat annular surface integral with or rigidly carried on the other member. The arrangement illustrated in Fig. 2 comprises a plastic, fibre or like sealing ring 15 held in rubbing contact with a flat annular surface 13 of the brake drum 11 by means of a rubber tube 14 which expands from a crescent shape towards a semi-circular section, as shown in Fig. 2, as the sealing ring 15 wears, thus keeping the sealing ring in contact with the brake drum 11 to prevent the entry of foreign matter. Angular movement of the sealing ring 15 and the rubber tube 14 is prevented by pegs 16 secured to the stationary back plate 10. In the general arrangement illustrated in Fig. 9, the brake drum 40 has a detachable shield 44 attached to it and the sealing ring 45, corresponding to the sealing ring 15 described with reference to Fig. 2, is resiliently urged against a flat annular surface of the shield 44 by means of the rubber tube 46 mounted by means of pegs 47 on the stationary back plate 41 of the brake. Various alternative arrangements are described and illustrated in the Specification including the replacing of the rubber tube 14 or 46 by a compression spring and plate arrangement to keep the sealing ring in contact with the brake drum as the sealing ring wears. In order that the interior of the brake drum may be maintained at a pressure substantially equal to that of ambient atmosphere, a breather pipe may be provided through the stationary back plate with its open end arranged well above the level of the water, mud or grit liable to contaminate the mechanism. The sealing member may be mounted on the brake drum and may be resiliently urged into rubbing contact with the stationary back plate.

Title: Process of producing 3, 4-dimethyl-5-phenyl-2-iminothiazolidine
IPC: C07D277/40
Filed: 1950-08-04
Abstract: The invention comprises 3,4-dimethyl-5-phenyl-2-iminothiazolidine in its racemic and in its optically active forms, and also its preparation by the action of a salt of thiocyanic acid on 1 - phenyl - 1 - halogen - 2 - methylaminopropane hydrohalide in the presence of a solvent or suspension medium and preferably in an alkaline medium. In a modification, the reaction components are first heated in an acid medium and the 1-phenyl-1-thiocyan-2-methylaminopropane so formed is then heated in an alkaline medium.  The optically active products are obtained by starting from the optically active 1-phenyl-1-halogen - 2 - methylaminopropane hydrohalogenides. Suitable solvents or suspension media are water, methanol, ethanol, butyl ether, chlorinated hydrocarbons, benzene and pyridine, and suitable alkaline materials are caustic alkali, ammonia, methylamine, aniline, ephedrine, pyridine and quinoline. In example (1), racemic 1 - phenyl - 1 - chloro - 2 - methylaminopropane hydrochloride is suspended in ethyl alcohol with ammonium thiocyanate and caustic soda or caustic potash and heated under reflux to yield the thiocyanate of 3,4-dimethyl - 5 - phenyl - 2 - iminothiazolidine; l - 1 - phenyl - 1 - chloro - 2 - methylaminopropane hydrochloride similarly treated yields the salt of d-3,4-dimethyl-5-phenyl-2-iminothiazolidine, and vice versa.  In other examples, the thiocyanic salt of 3,4-dimethyl-5-phenyl-2-iminothiazolidine is prepared by (2) heating a suspension of 1-phenyl-1-chloro-2-methylaminopropane hydrochloride in an aqueous solution of ammonium thiocyanate and sodium acetate; (3) heating a suspension of 1-phenyl-1-chloro-2-methylaminopropane hydrochloride with ammonium thiocyanate and a little hydrochloric acid, and heating the 1-phenyl-1-thiocyan-2-methylaminopropane hydrothiocyanate so formed in aqueous caustic soda; (4) heating 1-phenyl-1-chloro - 2 - methylaminopropane hydrochloride and ammonium thiocyanate in a mixture of ethylene chloride and pyridine; (5) heating a mixture of 1-phenyl-1-chloro-2-methylaminopropane hydrochloride, ammonium thiocyanate and l - 1 - phenyl - 1 - oxy - 2 - methylaminopropane suspended in ethylene chloride; and (6) by heating the thiocyanic acid salt of 1-phenyl-1-thiocyano-2-methylaminopropane and caustic soda in water.
