Title: Improvements in the manufacture and production of valuable hydrocarbons from gaseoushydrocarbons
IPC: C07C2/00
Filed: 1930-10-24
Abstract: Gaseous saturated or unsaturated hydrocarbons which contain no acetylene are converted to liquid hydrocarbons by heating to high temperatures in the presence of small amounts of catalytically active vapours of metals melting below 500 DEG  C., excluding the alkali metals, e.g. mercury, cadmium, lead, tin, or zinc.  The gases may be laden with metal vapours by being passed through or over molten or boiling metals, or by injecting into them metal vapours or indifferent gases, e.g. nitrogen or hydrogen, containing the said vapours, or by passing the laden carrier gas and the hydrocarbon separately into the reaction chamber.  The mixtures containing the hydrocarbons may include up to 2 per cent, or somewhat more, by volume of metal vapour.  The reaction may be carried out between 400 DEG  and 1100 DEG  C., and other catalysts, e.g. molybdenum, tungsten, chromium, graphite, or coke, may be used together with the metal vapours.  The walls of the reaction chamber may be constructed of or lined with tin, tin alloys, e.g. lead-tin alloys, chromium, or graphite, and the process may be carried out at ordinary or any elevated pressure.  Examples are given of the treatment of methane laden with mercury vapour, ethylene laden with mercury vapour, and a mixture of ethane, propane, butane, ethylene, propylene, and butylene laden with cadmium vapour, the products containing olefinic and aromatic and other liquid hydrocarbons.  Specifications 305,603, 309,199, and 334,178, [all in Class 2 (iii), Dyes &c.], are referred to.

Abstract: 314,745. Ziler, C. H. April 23, 1928. Divided on 314,625. Coiling.-In a machine for coiling wire springs the stock is slightly retracted after the formed spring has been severed therefrom so that it may be properly directed to the coiling mechanism to form the next spring. The stock 3 is fed by rolls 2 through guide rolls 4 and against a roil 5 carried by a lever 6 which is rocked by a cam 11, lever 10, adjustable tappet 9, and lever 8 to vary the diameter of the coil. After the spring has been severed at 26 from the stock the latter is retracted by a cam-operated arm 14 which is normally held in its forward position by a spring 16. The arm has a fixed jaw 18 and a pivoted spring-pressed jaw 19 which is normally held out of action by a stop 22 on the machine, but which is pressed by its spring 21 into contact with the wire when the arm 14 is moved backwards and so retracts the wire. The pitch of the coils is determined by a member 95 which co-operates with a member 96 having a finger 97 so as to compress the formed spring to give it the desired set. Specification 314,625 is referred to.

Suitable thermoplastic materials are polyesters, polyamides, polyester amides and polyvinyl compounds such as polystyrenes or polyvinyl acetate, having a softening point of from 200‹F. to 400‹F. The thermoplastic material is applied to the shoe upper by an applicator of the type described in Specification 1,096,792 so that the coating L has a tapered feather edge E. The coating may extend over part of the lasting margin, this portion being used to bond the lasting margin to the insole of the shoe.
