Title: Improvements in and relating to the manufacture of vehicle tyres
IPC: B29C43/24
Filed: 1968-06-25
Abstract: 1,219,806. Laminated tyre bodies. SEMPERIT OSTERREICHISCH - AMERIKANISCHE GUMMIWERKE A.G. 25 June, 1968 [26 June, 1967], No. 30318/68. Heading B5N. A vehicle tyre body is produced by continuously forming a base strip 1 of a first (black) rubber or synthetic rubber mixture and applying to its lateral portions in parallel spaced relationship continuously formed strips 3 of a second (white or coloured) rubber or synthetic rubber mixture to form the side walls of the tyre. The central portion 2 of the base strip is preferably thicker than the lateral portions and forms the tread. The assembly is subsequently vulcanized. In one apparatus for producing the tyre body, the first mixture 6 is calendered by rollers 19, 20, 24 and 25 and the resulting strip 9 is trimmed and divided by cutters 7 to form three base strips to each of which is laminated a pair of side-wall strips cut by cutters 5 from a strip produced by calendering rollers 28, 29 and 30 from the second mixture 13. The waste material from each of the cut strips is fed back to the respective calendering rollers. The base and sidewall strips are laminated by heat and pressure between a roller 16 and a belt 15, the arrangement being angularly adjustable by an hydraulic device 14. The composite strips 17 are fed via a conveyer belt 12 to a cooling bath 18.

A railway vehicle bogie comprises a bolster 5 connected by swing links 8 to the bogie frame 7, and a beam 2 supported on the bolster by springs 6 and carrying the vehicle superstructure 1 through side bearers 3 thereof and a pivot pin 11 thereon engaging a bearing pin 12 in the beam, the latter transmitting tractive and braking effort between the bogie and superstructure independently of the bolster through the agency of pairs of links 10 connecting the beam 2 and the frame 7 and also by the pivot pin 11. The side bearers 3 engage the beam in oil baths 4 thereon. The beam is constrained to move vertically only relative to the bolster by guide means 9 within the springs 6, and is prevented from rotation relative to the frame by the links 10 which however permit transverse movement of the beam. The superstructure is free to pivot relative to the beam 2 against damping due to the friction of the side bearers thereon. Transverse movement of the superstructure is restrained by bell crank lever and spring devices 13, between the frame 7 and beam 2.

Abstract: 794,705. Naphthalene. AMERICAN CYANAMID CO. Oct. 8, 1956 [Oct. 11, 1955], No. 30572/56. Class 2 (3). Naphthalene is purified to remove polymerizable impurities or is recovered from an aqueous dispersion of naphthalene sulphonates containing polymerizable impurities by a process which comprises heating the naphthalene or dispersion with a strongly acidic polymerization catalyst to above 150‹ C. until the sulphonates are hydrolysed and the polymerizable material polymerized, producing an aqueous phase of specific gravity at least 1.07 and separating naphthalene and polymerized material. The aqueous dispersion of sulphonates may be produced by washing a sulphuric acid-washed crude naphthalene with water or aqueous alkali or an effluent from the production of #- naphthol involving sulphonation of naphthalene. The polymerizable impurities include thionaphthenes in naphthalene and sulphonates of thionaphthenes in the aqueous dispersion. Acidic polymerization catalysts include sulphuric, hydrochloric and phosphoric acids, the former being preferred. Using sulphuric acid, the concentration is preferably such that the aqueous layer throughout the process contains not less than 10 per cent and not more than 50 per cent sulphuric acid. The concentration should not be so high that the product contains significant amounts of sulphonated material. Preferred temperatures are between 150‹ and 350‹ C. If sufficient acid is not present to produce the required aqueous phase specific gravity of 1.07 then further inorganic material may be added. Naphthalene is separated from the polymerized material by distillation or steam distillation.
