Title: Process for the polymerisation of ethylene and catalyst therefor
IPC: C08F110/02
Filed: 1958-01-30
Abstract: Polyethylene of molecular weight 50,000-750,000 is produced from ethylene by means of a catalyst prepared by mixing at 20-80 DEG C. 1-1,5 mols of dialkyl aluminium monochloride (preferably Et2AlCl) with 1 mol. TiCl4 for a period (e.g. at least 24 hours) sufficient to ensure that the mixture contains no TiCl4.  Optional additions to the reaction mixture, per kg of catalyst, are (a) 2-200 1,02; and (b) 1-10 gram-mols of an alcohol.  Supplementary portions of dialkyl aluminium monochloride may also be used.  In the example, polymerization was carried out continuously, using as reaction medium a C7-10 hydrocarbon fraction, formed in the hydrogenation of CO, which had been purified by hydrogenation over Ni, followed by intensive drying and treatment with said TiCl3.  Specifications 824,198 and 875,073 are referred to.

Filed: 1959-01-30
Abstract: 881,010. Making vehicle axles; stamping. RUBERY OWEN & CO. Ltd. April 28, 1960 [Jan. 30, 1959], No. 3328/59. Classes 83 (4) and 83 (2). The ram or slide of a power press for the production of pressings each forming one half of a vehicle axle is provided with control pins for the blank which are movable in a direction parallel to the line of movement of the ram or slide and are loaded by compressed-air at substantially constant pressure. The pressing 10 is formed between a stationary bottom tool 11 mounted on a plate 12 secured to a bed 13 and a reciprocable top tool 14, mounted on a top plate 15 actuated by a ram 16. The top tool carries guide pins 17 working through bushes 18 in the bottom tool 11. After the forming operation the pressing is ejected from the bottom tool by lifter pins 19. Control of the pressing is effected by headed control pins 20 which are engaged by pins 22 extending downwardly from a transverse bar 23 vertically slidable in the ram 16. The bar is loaded at its ends by the piston-rods 24 of compressed-air cylinders 25 (Fig. 5), in which the pressure is maintained constant. The pins engage the blank after the top tool has moved downwardly through a predetermined distance and locate the blank positively and accurately in the bottom tool during the rest of the movement of the top tool. On completion of the pressing operation the top tool moves upwardly but the control pins 20 remain in engagement with the pressing and strip the pressing from the top tool. During ejection of the pressing from the bottom die by the lifter pins 19 the control pins continue in engagement with the pressing thus effecting a smooth release of the pressing and minimizing the risk of distortion,

Title: Method of preparing gelatine
IPC: C09H3/00
Filed: 1947-02-06
Abstract: Gelatine is prepared by treating a gelatine-containing material at an elevated temperature with an aqueous solution of ammonia or a non-cyclic amino compound containing not more than three carbon atoms in the molecule, and separating the gelatine from the solution.  The gelatine-containing material, e.g. fresh, dried or salted hides, raw, degreased or acidulated bones, sinews, feet, or other parts of animals, are preferably reduced to pass a 50 mesh B.S. sieve, and are treated with a solution of preferably 10 - 30 per cent concentration of ammonia or an aliphatic amine, such as methylamine, dimethylamine, ethylamine, ethylene diamine, ethanolamine, propanolamine or propylene diamine, at a temperature of about 130 DEG  F.  The pH is maintained at 9 - 10 by buffering salts such as ammonium carbonate, acetate, chloride, sulphate, acid phosphate, citrate or tartrate. The gelatine is removed by (a) evaporating under reduced pressure and adjusting the pH to 7; (b) salting-out, preferably at a pH of 1 - 4; this could be accomplished by adding acid to neutralize the ammonia or amine, or, if a buffering-salt has been used, by adding acid to reduce the pH; or (c) by precipitation by adding an organic solvent in which gelatine is insoluble, e.g. acetone or ethyl alcohol.  The gelatine is redissolved if necessary and the solution is filtered, and chilled and the gelatine obtained is washed and dried.

Abstract: 215,114. Marks, E. C. R., (Corona Typewriter Co., Inc.). Feb. 6, 1923. Sheet.feeding arrangements. - A frame arranged under the platen 17, Fig. 6, carries front and rear feedrollers 29 which are released in two movements bv a rockable cast-off shaft, which first engages and depresses the rear parts of the feed-roller frames to release the rear feed-rollers, the subsequent movement causing the frame to move down bodily to release the front feed-rollers. The feed-rollers are arranged in two sets, one set to each end of the platen. Each set is carried on a substantially rectangular frame comprising the front and rear shafts 30. 31 and a pair of flat bars 34 provided with upstanding ears 33, 35 at their front and rear ends respectively, to form journals for the corresponding shafts. Two rollers 29 with a loose spacing-sleeve 32 are shown on each shaft. The rockable shaft comprises a sheetmetal bar 18 with a rear stiffening-flange 21, and with its ends 19 bent down and pivotally supported on screws 20 passing through the end flanges 16 of the platen carriage 15. Lever fingers 22 projecting forwardly from the front edge of the bar 18 are bent to form hooks 23 at their ends, which are disposed the rear ends of the bars 34 and the shafts 31. Each feed-roller frame is supported upon a flat sheet-metal bar 38 which has its ends arranged loosely beneath the end bars 34. The bars 38 are widened midway and provided with hooks 48 engaged within slots 47 in transverse plates 39 to form a pivotal connection. The ends 40 of the plates 39 are offset to form pivots 41 journaled within ears 42 struck up from the platen carriage. The plates 39 are normally pulled towards the platen by a spring 43 connected between a pair of upstanding arms 44 integral with the rear ends 40 of the plates. The rocking-shaft is actuated by a cam pivoted upon the platen shaft 17<1> and provided with two working faces to co-operate with an arm 27 offset from the right-hand end of the bar 18. On the initial rocking of the bar 18 the fingers 22 bear upon the rear ends of the bars 34 and tilt them about the front shaft 30 to the position shown in Fig. 6. Several, preferably four, of the ears 35 at the rear ends of the bars 34 are extended to form hook-like levers 45 which contact with the rocking-bar 18 when the rear feed-rollers are released. On further movement the rocking-bar bears against the hooks 45, thereby tilting the bars 34 to carry the forward feed-rollers away from the platen. In this position the spring 43 is fully extended and the plates 39 are in contact with the upper face of the platen carriage.
