Abstract: 405,292. Casting-machines. DURAFER, Inc., 744, Broad Street, Newark, New Jersey, U.S.A. Aug. 2, 1932, No. 21637. Convention date, Aug. 1, 1931. [Class 83 (i).] A centrifugal casting-machine comprises a rotating horizontal table 13 which co-operates with a mould ring 19 which is raised therefrom to strip the casting. The table is carried by the spindle 17 of an electric motor 12 and has a concave face 14 onto which the molten metal is poured. The ring 19 rests on the table 13 or, as shown, on a lower mould ring 18 and is connected by rods 29 to a ring 31 engaged by rollers 30 of a treadle 36 by which it can be raised. When a lower mould ring 18 is used this is moved down, as the ring 19 is raised, by means of rods 20<1> a ring 20 and levers 44 each having a roller 42 on one end engaging the ring 20 and a roller 43 on the other end engaging the ring 31. In a modification the mould rings 18, 19 are connected to sleeves 131, 126, Fig. 4, to which are pivoted levers 142, 140 having common pivots 139 each adapted to slide in a groove 137 of an arm 134 mounted on the spindle 17. The levers 140 are extended beyond the pivots 139 and carry weights 141 which, when the rotation is sufficiently rapid, hold the mould parts together but, when the speed is reduced, separate them. In another modification the ring 18 is omitted and the pivots 127 are fixed so that the weights 141 raise the ring 19 when the speed is reduced. The mould itself may be made by centrifugal casting and the volume of the cast article is determined by a flange 24. The Specification as open to inspection under Sect. 91 comprises also arranging the volume of the mould to be up to six times the volume of the casting so that it remains at the correct temperature when used continuously. This subject-matter does not appear in the Specification as accepted.

Filed: 1932-08-05
Abstract: 405,335. Cutting tobacco. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., East Street, Bedminster, and COATES, A. F., Codrington Grange, Broadway Road, both in Bristol. Aug. 5, 1932, No. 21981. [Class 5 (i).] Tobacco leaves are arranged with their stems substantially parallel while on their way to a cutting machine, by means of a number of endless conveyers arranged side by side and having different movements imparted to them. Fig. 1 shows a feeding-device in which the tobacco leaves are fed by a hopper 21 on to a band 5, which is slowly raised by ratchet gear 15, 16 rotating a pulley 9, to which one end of the band 5 is attached after passing over a fixed pulley 8. The tobacco leaves are then raised and fall over a slanting plate 59 on to a series of six conveyer bands 26, 29 arranged side by side and moved at different speeds. This is effected by passing the bands over pulleys of different sizes on the driving-shaft 25. The bands also pass over pulleys on other shafts 22, 23, 24, those on the last-mentioned shaft being loosely mounted thereon and of varying sizes conversely to the sizes of the driving-pulleys on the shaft 25. The differing speeds of these bands bring the leaves into the required parallel relationship, and they then pass over an oscillating chute 37 on to a conveyer band 49, being fed by this under a second band 50 and into a mouthpiece 55, over which reciprocates the cutting-knife 56. A pressing-down plate 57 oscillates at the rear of the band 50. The chute 37 may be divided into two or more chutes side by side. Specification 405,334 is referred to in the Provisional Specification.

Title: A process for the production of valuable higher molecular aliphatic and/or cyclo-aliphatic compounds
IPC: C07C303/24
Filed: 1936-08-10
Abstract: Products stated to have wetting and dispersing properties are obtained by sulphating the unsaturated polymerization products which are prepared by subjecting unsaturated aliphatic hydrocarbons or mixtures containing the same to a polymerization treatment.  The latter may be effected by the processes described in Specifications 202,311, 291,137, [both in Class 2 (iii)], 360,331 and 443,679.  The sulphated products may be converted into soaps, which since they are soluble in organic solvents are suitable for the manufacture of dry cleaning soaps, spray oil and coal-oil dispersions, and may also be converted into ethers, esters or alcohols.  The olefinic starting materials may be prepared by cracking or dehydrogenating mineral or tar oils or paraffin wax, by dry distillation of coal or by chlorinating saturated hydrocarbons and splitting off hydrochloric acid.  For the polymerization, floridine, alumina, boron fluoride or aluminium or zinc chloride may be used as catalysts.  In examples: (1) a mixture of olefines obtained by cracking a benzine fraction and by vapour phase cracking of spray wax is polymerized in the presence of benzene using aluminium chloride as catalyst, the product is decomposed with hydrochloric acid, washed with water and distilled; the resulting oil is sulphated with sulphuric acid of 90 per cent strength in benzine; (2) the sulphuric ester of example 1 is hydrolized by heating with water and steaming to obtain an alcohol; (3) the product of example 1 is neutralized with caustic soda, mixed with ether and heated to 100 DEG  C. at 20 mms. pressure.  A sample furnished under Sect. 2 (5) is prepared from cracking gases containing propene and butene by polymerization, using a phosphoric acid-kieselguhr catalyst, and sulphation with sulphuric acid followed by neuttralization.
