Title: Improvements in the production of polymers from olefinically unsaturated hydrocarbons
IPC: C08F2/00
Filed: 1956-10-04
Abstract: A crystalline catalyst suitable for use in the polymerization of olefinically unsaturated hydrocarbons is made by reacting aluminium with a titanium halide in the presence of a halogen-containing aliphatic compound and optionally aluminium chloride and/or a halogen such as chlorine, bromine, or iodine, or a halogen hydracid e.g. hydrochloric acid.  The reaction may be carried out at temperatures between room and 100 DEG  C.  After the reaction any excess halogen compound is distilled off and the catalyst separated with the aid of an organic precipitant such as dimethylcyclohexane.  Specified titanium halides are the tetrachloride, tetrabromide, and trichloride.  The halogen-containing compound may be ethyl chloride or bromide, propyl or butyl chloride, methylene chloride, ethylene chloride, ethylene bromide, chloroform, trichlorethane, or carbon tetrachloride.  In the preparation of the catalyst generally 1 mol. of titanium halide is reacted with 2 to 8 mols. of aluminium and the aluminium chloride when present is used in an amount up to 5 times the amount of the halide.  Specification 781,837 is referred to.ALSO:Olefinically unsaturated hydrocarbons are polymerized, e.g continuously in the absence of any halogen-containing aliphatic compound in the presence of a catalyst obtained by the reaction of aluminium with a titanium halide in the presence of a halogen-containing aliphatic compound and optionally aluminium chloride, and/or a halogen or halogen hydracid.  In the preparation of the catalyst any excess halogen compound is removed.  Hydrocarbons mentioned are ethylene, propylene, butylene, isobutylene, and mixtures, and butadiene, isoprene, and styrene.  The polymerization may be effected in the presence of diluents such as pentane, octane, cyclohexane, gasoline, or aromatic hydrocarbons, and at temperatures between - 120 DEG  and 200 DEG  C.  The titanium halide used in the preparation of the catalyst may be titanium tetrachloride, titanium tetra-bromide, or titanium trichloride.  The halogen-containing compound may be ethyl chloride or bromide, propyl or butyl chloride, methylene chloride, ethylene chloride, ethylene bromide, chloroform, trichlorethane, or carbon tetrachloride.  The polymer may be purified by washing with methanolic hydrochloric acid, water, or tetrahydrofurane, and made into films, foils, fibres, or threads. Specification 781,837 is referred to.

Abstract: 248,294. Ward, E. A. Dec. 1, 1925. Addition to 200,278. Cleaning internally, non- rotary appliances for. -The parent Specification describes a sectional shaft, each section of which is formed from a number of straight resilient steel wires arranged in parallel relation, so that adjacent wires are in lateral contact, and which are held together by coating with molten metal. Two spirally arranged flat springs are wound around the wires with an intermediate binding of string to form a flexible coating. According to the present invention the wires are enclosed by a spirally arranged spring 6 disposed edgewise to the length of the wires forming the core, to increase the diameter of the shaft without materially increasing its weight. The intermediate spacing 7 is filled with string binding, and is enclosed by a resilient waterproof coating 8. The coating 8 may be formed of pitch and resin combined; by a mixture of gutta-percha, pitch, resin, and boiled oil; or by a mixture of sawdust and painters' knotting. Also, the spaces between the coils may be filled by spirally wound cane, rubber, &c., or they may be left open. The casing 8 may either cover the spring 6 completely, or finish flush with the edges thereof.

Abstract: 1,269,023. Metal gluconates. JOH. A. BENCKISER G.m.b.H. 25 June, 1970, No 30886/70. Heading C2C. Difficultly soluble divalent metal gluconates e.g. calcium, magnesium and iron gluconates, are prepared by slowly passing a solution of soluble monovalent metal gluconate over a cation exchange resin in divalent metal form. The gluconate ion passed in solution is approximately equivalent to the divalent metal ion and the concentration of the divalent metal gluconate is sufficient to precipitate the salt. The monovalent metal gluconate solution may be a crude obtained by fermentation or electrolytic oxidation, and the preferred cation exchangers are derived from polystyrene and phenol derivatives with active sulphonic acid groups.

Abstract: 758,713. Floor treating machines. TRUVOX, Ltd. Nov. 20, 1953 [Dec. 5, 1952], No. 30967/52. Class 138(1) A floor treating machine comprises a carriage 10, Fig. 4, a steering handle 33 pivoted to the carriage and valve means 14 for supplying cleansing liquid to brushes 11, pads or the like rotatably mounted on the carriage, in at least two alternative and predetermined ratios of flow a manually operable mechanism being provided for operating the valve means which are automatically closed when the handle 33 is pivoted to a parked position. A cleansing liquid tank 16 is detachably mounted on the carriage 10. In the base 15 of the tank is the valve means 14 operable by a lever 27, linkage 29 and pivoted hand lever 30. The lever 30 has a spring-pressed ball 31 coacting with a series of notches 32 for holding the valve in its closed or two open positions. The handle 33 when moved to the vertical position also moves the lever 30 to close the valve. Referring to Fig. 2, the valve means 14 comprise an annular collar 17 secured to the base 15, a valve plate 18 secured to the collar with the interpositioning of an apertured gasket 19 and a valve disc 23 having an operating pin 22 urged downwardly by a compression spring 24. The disc 23 normally seats on the gasket to close the valve. Two conical plugs 26 on the disc co-operate with two circular apertures 25 in the plate 18. According to the distance the pin 22 is raised, the annular spaces between the plugs 26 and the apertures 25 will be different in sizes so that liquid will flow therethrough at different rates and through an opening 12 in a distributer channel 13 formed in the carriage 10. In a modification separate valve means may be provied for each brush. The supply of liquid to each brush may be controlled by inindividual valve means. Each separate valve means may comprise two separate valves, one being opened first, to then remain open when the second valve is opened. More than two rates of supply may be provided. If the tank 16 is removed from the machine the valve means 14 is automatically closed by the spring 24.

Title: Cloth measuring machines
IPC: G01B5/04
Filed: 1926-12-07
Abstract: 272,392. Vanderveld, A. Dec. 7, 1926. Measuring.-A cloth measuring machine is provided with means, e.g. a metal plate 90, for covering the readings should the measuring operation be started with the cloth beyond its proper starting point and also with a bar 93 which prevents any attempt to introduce cloth between the measuring and pressor roller 9, 51 when the same are in contact. The invention is shown applied to a measuring and cost-computing machine as described in Specifications 194,891 and 241,265. When the lever 60 is depressed to lower the presser roller 51 through the cam and lever 66, 67, it raises the bar 93 by means of the pin and cam 92, 98<a> and lowers a frame 70 pivoted on a shaft 68 by means of the arm 91 and cam 69. An extension 72 of the frame is provided with a lip 73 and a pin 75 on which is pivoted an integral cam 77 and block 76 which dips into a recess in the table 43. One face of the block is the proper starting point for the cloth to be measured but if the cloth projects beyond this point the block 76 is swung about its pivot 75 and, either by means of the cam 77 or a spring wire 78, moves a two-legged lever 81 which through a pin 88 and shaft 86 moves the plate 90 over the readings. A lip 84 on the lever 81 has now passed beyond the lip 73 and if the cloth is not readjusted to allow the block 76 to return tn a vertical position, the lips 73, 84 would engage when the lever 60 was released to raise the presser roller 51 and the plate 90 would remain over the readings. On the release of the lever 60 the bar 93 falls, and its pivoted end 95 passes into a slot in the table 43, as shown in Fig. 3, if no cloth is present, it is knocked into a horizontal position clear of the cloth and held there by a spring 99 and projection 97 on the bar 93. When the bar 93 is next lifted, its end 95 contacts with a stop 101. and is again moved into a position in line with the bar 93 as shown in Fig. 3.
