Title: Improvements in the manufacture and production of anti-knock motor fuels by the treatment of hydrocarbon oils at elevated temperatures
Filed: 1937-09-06
Abstract: 503,602. Cracking and polymerizing oils. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Sept. 6, 1937, No. 24321. [Class 32] [Also in Group IV] Anti-knock fuels are produced by cracking in the vapour phase at temperatures between 400 and 700‹C. hydrocarbon oils consisting wholly or substantially of unsaturated hydrocarbons boiling at least for the greater part above the boiling point of benzines, while adding cyclic hydrocarbons, particularly mono-nuclear aromatic hydrocarbons, e.g. benzene, toluene, xylene, which are vaporous under the reaction conditions, the reaction being carried out in the absence of substantial amounts of hydrogen or gases supplying hydrogen. Oil fractions rich in unsaturated hydrocarbons and boiling above 200‹ C. for use as the initial materials are obtained by cracking mineral oils, tars, e.g. mineral oil or brown coal tar fractions containing wax, products of the destructive hydrogenation of coals, tars, oils &c., or oils, produced by the reduction of carbon monoxide. The reaction is preferably carried out in the presence of catalysts, the sulphides, oxides, phosphates, halides, or sulphates of iron, cobalt, nickel, chromium, vanadium, aluminium, zinc, tin, manganese, tungsten, or molybdenum being specified and used preferably on carriers pretreated with acids, e.g. hydrogen fluoride. The reaction may be carried out in the presence of halogen or sulphur compounds. Polymerization of any low-boiling unsaturated products is effected in a further reaction zone filled with polymerizing catalysts, e.g. metal halides, phosphoric acid, boric acid, or these catalysts may be mized with the catalysts in the cracking zone. In the example, a fraction of boiling orange 150-300‹ C., obtained by cracking brown coal paraffin wax, is mixed with an equal amount of benzene and heated to 510‹ C.. in a tubular reaction chamber under 150 atmos. pressure. The product is distilled to separate a fraction boiling between 140 and 200‹ C. which after refining with sulphuric acid or bleaching earth gives a good anti-knock fuel with a flash-point of 40‹ C.

Abstract: 207,638. Browett, T. Sept. 8, 1922. Spring wheels.-A resilient wheel particularly for heavy motor vehicles comprises two discs 1 carrying' a U-section tyre 4, and an intermediate floating disc member 8 supporting the tyre tread and capable of radial movement so that the weight of the vehicle transmitted through the members 1 puts the lower part of the tyre in compression and the upper part in tension. Members 1 have inturned spacing sleeves 2, one member being riveted to a flange on an inner sleeve 3, and the other held by a nut 3<a>. The tyre may be secured by clamping rings 5 or may be held on a flange on members 1 by endless metal bands. Member 8 is slightly larger in diameter than the tyre, so that the latter is stretched when assembled. If necessary to facilitate insertion, the outer portion may be in the form of ring segments 11 inserted separately and then bolted together. As shown, the centre part of member 8 is in two dished portions riveted together. In a modification, the central portion is a single plate stiffened by radial corrugations and having segmental flanged members riveted to its periphery. For driving wheel &c. an Oldhamtype coupling member 13 is introduced, having feather and groove connections 14, 15, at right angles to one another, with member 8 and one member 1. This construction also allows members 1 to be laterally strengthened by cross-stays, the central opening in member 8 being large enough to clear the stays. The invention may be adapted to twin wheels, and a lubricant such as graphite may be introduced within the wheel.
