Title: Improvements in and relating to the production of halides of unsaturated aliphatic acids or derivatives thereof
Inventor: LONG RICHARD
IPC: C07C51/58
Filed: 1962-08-31
Abstract: Halides of unsaturated aliphatic carboxylic acids are prepared by contacting a compound containing the grouping <FORM:0987274/C2/1> wherein X is a halogen atom and the free valencies indicated are attached to hydrogen atoms or alkyl groups, with carbon monoxide in the presence of palladium or a complex or a salt thereof at a temperature of at most 250 DEG  C. and at a pressure of at most 3000 atmospheres.  The acid halides may be reacted subsequently with water, an alcohol, ammonia or an amine to give, respectively, the corresponding acid, ester or unsubstituted or substituted amide. In a modification of the process the acid, ester or amide is produced directly by conducting the carbonylation reaction as above in the presence of water, an alcohol, ammonia or an amine. Specified catalysts are metallic palladium, palladous chloride, p -allyl palladium chloride, p -methallyl palladium chloride and p -crotyl palladium chloride.  Examples are given.  The following conversions of starting materials also occur in the examples:-(6) 1-chlorobut-2-ene to 3 - chlorobut - 1 - ene; (7) 3 - chlorobut - 1 - ene to 1-chlorobut-2-ene; (8) methallyl chloride to tertiary-butyl chloride.

[Also in Group XVI] In an embossing machine operation of a hand lever rotates shafts 49, 58 varying amounts. A die anvil cam 64 on the shaft 49 acts through a follower 100 and a lever 101 to actuate an anvil 105 which becomes locked in its depressed position by a toggle spring 109 until positively returned on the return of the operating lever. After the die anvil 105 has been locked a punch anvil cam 60 on the shaft 58 acts through a follower 70, lever 71, links 75, 77, 81 to pivot links 83 between a base member 88 and an anvil 87 so that rollers 84-86 operate the latter to force a punch 201 towards a die 200 until positively returned by the reverse action of the operating lever. The embossing force can be varied by altering the position of the base member 88 by turning an eccentric shaft 89.

Title: Improved process for the preparation of oximes from cyclic ketones
Filed: 1946-11-14
Abstract: Oximes of cyclic ketones in which the ketone group is in the ring are prepared by converting the ketones into the corresponding bisulphite compounds and reacting the latter with nitrous acid or salts thereof, preferably at temperatures below 0 DEG  C.  The bisulphite compounds are advantageously prepared by treating an aqueous mixture of the ketone with SO2 and subsequently adding Na2SO3.  In an example, the bisulphite compound of cyclohexanone is prepared and is converted to cyclohexanone oxime by treatment with sodium nitrite.

Filed: 1920-12-01
Abstract: 176,132. Shaw, J. K. Dec. 1, 1920. Boards; paper-machines; pulp, adding special substances to.-Fibre boards, which can be used as heat-insulating material for a wall covering, or as a substitute for lumber in the manufacture of furniture, trucks, &c., are made from bagasse or similar fibres which have been only partially cooked, so that some of the pith 4, Fig. 4, is left adhering to the fibres as protuberances, and some broken fibres 3 project from the fibrous bundle 2 to assist in producing a felting effect, such as is found in wool fibres. A mixture of the fibres, after they have been beaten and screened, and water is introduced into a tank 6, Fig. 1, and after flowing over baffles 8 the water flows away through a perforated travelling apron 10 and a rotating perforated cylinder 13, leaving the fibres adhering to these surfaces. Further fibres flow into the angle 12 between these surfaces and the whole mass of entangled fibres after pressure by a roller 16 passes out of the machine. The pressure exerted is light if a heat insulator is required and heavy if a substitute for lumber is to be obtained. Fibres, such as those from wood, &c. may be mixed with the bagasse &c. fibres. In the preparation of the fibres water soluble compounds are formed by the alkali and the outer casing material of the bagasse, and these can be precipitated by aluminium sulphate upon the fibres to assist in binding them together. The fibres are beaten so as to form bundles of differing sizes by means such as a Hollander.
