Title: Improvements in or relating to shock-absorbers
IPC: F16F7/06
Filed: 1928-08-15
Abstract: 297,316. Ram, G. H. E. de. Sept. 17, 1927, [Convention date]. Vibration-dampers. - In means for damping the vibrations of vehicle springs, the oscillations of a shaft within a cylindrical body member are frictionally resisted by a disc which is subject to axial forces applied by a piston supplied with liquid under pressure from piston pumps actuated by the oscillating movements. The shaft 2 is connected by an arm 3 to the axle and oscillates within the body member 1 secured to the frame, the end movement of the shaft being controlled by a washer 10 and a screwed cap 7. A disc 6 keyed to the shaft 2 is pressed lightly against the cup 7 by springs enclosed within a piston 5 fitting a cylinder within the end of the shaft 2. Additional pressure on the disc 6 is derived from liquid supplied under pressure to the piston 5 by pistons 13 which are pressed outwards by springs against shoes 12 engaging a cam or eccentric groove in the cylindrical body 1. Liquid passes from the piston 13 through one way valves 17 to the piston 15 and escapes therefrom through valve 20 and passages 18, 19 into the body of the apparatus from which it returns to the pistons 13 through passage 15 and one-way valves 16.

Title: Improvements in or relating to polymeric substances
Inventor: CHARLESBY ARTHUR
IPC: C08J5/12
Filed: 1952-09-24
Abstract: Polymers, e.g. polyethylene, polystyrene, and polyvinyl chloride, acetate or alcohol, which have been irradiated with ionizing radiations, e.g. with up to 4 units, so as to increase their resistance to organic solvents and cold drawing, are welded together by interposing polymers of the same composition which have received a substantially smaller amount of ionizing radiation, e.g. less than 1 unit, and subjecting the whole to pressure at a raised temperature. In an example, sheets of polyethylene irradiated with 4.7 units are welded together by interposing a film irradiated with 0.25 units and subjecting to pressure at 110 DEG  C. for half an hour.  In a modification, two polythene powders irradiated with larger and smaller amounts are mixed and moulded by normal thermoplastic moulding technique. Specifications 732,047 and 739,709 are referred to.

Title: Improvements in the manufacture and production of hydrocarbons and especially those of low boiling point
IPC: C10G1/08
Filed: 1927-09-12
Abstract: 307,946. Johnson, J. Y., (I. G. Farbenindustrie Akt.-Ges.). Sept. 12, 1927. Cyclic and acyclic hydrocarbons.-Hydrocarbons of low boiling point are obtained from carbonaceous materials, e.g. coals, tars, mineral oils, &c. by heating such materials to about 450‹ C. in the presence of catalysts comprising oxides of the metals or metalloids of groups 3-7 deposited in small amounts on the metals aluminium, silver, manganese, chromium or chromium-nickel alloy. The reaction is preferably conducted under high pressure, e.g. 200 atmospheres and in the presence of hydrogen or gases containing hydrogen. The oxides are deposited in the carrier metal by etching the latter with hydrochloric acid and then treating it with an acidified solution of the salt of the metal to be deposited, or by electrochemical means, or by intimately mixing in a ball mill granules of the metals with small quantities of the oxide. The metal walls, pipes and stirring devices of the reaction vessel mav be activated in a similar manner. Mineral oil boiling above 270‹ C. is passed with excess hydrogen at 450‹ C. and 200 atmospheres through an aluminium lined vessel containing a catalyst comprising aluminium granules activated with 1-2 per cent of uranyl nitrate. The activation is carried out by treating the aluminium granules with uranyl nitrate solution containing 3 per cent hydrochloric acid, evaporating to dryness, and reducing with hydrogen. Other catalysts used are aluminium gauze activated in presence of a solution of ammonium vanadate and uranyl nitrate, and silver wool activated by evaporation in a suspension of molybdenum oxide. According to the Provisional Specification compounds of cobalt, ruthenium, platinum, gold, and cadmium may also be used as catalysts. The process is also applicable to the dehydrogenation of hydrocarbons, tar, oils, &c. or for their conversion into aromatic hydrocarbons. In such cases a working temperature of 550-650‹ C. is used. Specification 268,774 is referred to.

Title: Process for the production of new anilides and salts thereof
IPC: C07C237/00
Filed: 1957-07-03
Abstract: The invention comprises acid anilides and their acid addition salts of the formula <FORM:0835803/IV (b)/1> wherein R1 and R2 are straight or branched alkylene radicals, Am is a secondary or tertiary amino group or a nitrogen atom forming part of the ring system of a heterocyclic base, e.g. pyrrolidino, R3 is chlorine, bromine or a methoxy group and X is oxygen or sulphur.  The compounds may be prepared by reacting an acid anilide <FORM:0835803/IV (b)/2> with a compound of the formula X1-R2-Am, in which one of the symbols X1 represents a halogen atom and the other the group HO-or HS-, or by reacting an o-chloro-, bromo- or methoxy aniline, or a salt or reactive derivative thereof, with an acid Am-R2-X-R1-COOH or a reactive derivative thereof, e.g. halide, ester or anhydride. Products in which Am is unsubstituted or monosubstituted may be formed initially and converted to secondary or tertiary amino compounds by alkylation or aralkylation with reactive esters of alkanols, alkenols, alkynols and aralkanols or with aldehydes or ketones and reducing agents.  The products are used as local anaesthetics, suitably in the form of their salts with acids such as sulphuric, hydrochloric, hydrobromic, phosphoric, acetic, glycolic, citric, succinic, fumaric, maleic, dihydroxy-maleic, methane-sulphonic and hydroxyethanesulphonic.  Specified products include N-b -diethylaminoethoxy-acetic-2-chloroanilide and the N-b -dimethyl-and diethyl-aminoethyl-thioacetic 2-chloroanilides. Mercaptoacetic acid-2-chloranilide is made by the action of thioglycollic acid on o-chloraniline.
