Title: The preparation of threads, fibres, straws, films, sheets and the like from cellulose esters
IPC: D01F2/28
Filed: 1939-08-30
Abstract: 543,484. Artificial silk &c. CHARBIN, R. Aug. 30, 1939, No. 24920. Convention date, Sept. 19, 1938. [Class 2 (ii)] Cellulose ester threads, fibres, straws, films, sheets and the like having an increased affinity for dyes are obtained by spinning a cellulose ester solution containing a swelling agent for the cellulose ester into a coagulating or setting medium and subsequently removing the swelling agent from the coagulated products. Swelling agents specified are metallic salts such as sodium fluosilicate, pyrophosphate, or borate ; potassium periodate or acid oxalate ; ammonium bichromate ; cobalt sulphate ; lead, zinc, or magnesium formates, acetates, citrates, tartrates and lactates. Also oxalic, adipic, sebacic, benzoic, toluic, cinnamic, anisic, cuminic, phenylacetic, diphenylacetic, naphthoic, and similar acids and their nitro compounds, nitro and nitroso naphthols, nitroerytbrite, mono- and di-hydroxy-diphenyls and hydroxyanthraquinones. The swelling agent may be employed in proportion from 2 to 10 per cent. of the cellulosic ester. In an example a solution of cellulose triacetate in concentrated formic acid is incorporated with a solution containing 5 per cent. of zinc formate calculated on the weight of cellulose acetate present and spun in cold water. The thread is then washed in water at from 70‹ to 80‹C. so as to completely dissolve out the zinc salt. In another example cellulose acetate of 54 per cent. acetyl content is dissolved in 95 per cent. acetone, mixed with 2 per cent. salicylic acid, and spun in a bath of kerosene. The thread is finally washed in hot water to fully dissolve the salicylic acid. Reference has been directed by the Comptroller to Specifications 184,197, 258,582, [both in Class 2 (ii)], 400,180 and 459,781.

Title: Improvements in and relating to shaping and/or contracting cylindrical articles
IPC: B21D26/02
Filed: 1947-09-11
Abstract: 633,183. Stamping. BENSON, W. E. Sept. 11, 1947, No. 24987. [Class 83 (iv)] Apparatus for shaping an open-ended cylindrical blank comprises a circular die which is transversely divided into two axially separable parts, a pressure sleeve which surrounds the die in a fluid-tight manner when its two parts are brought together and means for supplying fluid under pressure to the inner surface of the sleeve to deform the blank into close contact with the die. The parts 6 and 5 of a two-part die shaped to form a wheel rim to receive a pneumatic tyre, are mounted on a base-plate 7 and on a movable platen 8 respectively. When the die parts are brought together, a cylindrical sleeve 9, with sealing gaskets 15, 16 let into its upper and lower edges, is clamped between the base 7 and platen 8 to form a fluid-tight housing. The cylindrical blank 10 fits within the sleeve 9, its ends being received in slots 11 and 13 between the sleeve and the outer surface of flanges 12 and 14 on the base and platen. Oil, water or a mixture of sawdust and fat is supplied under pressure through a nipple 19-into a circumferential recess in the wall 9, thereby forcing the blank into conforming contact with the die. The die has four bores at right angles in which are plungers 25 with points 26 adapted to bite into the sleeve on the application of pressure fluid through a nipple 24 and so ensure that the axial flow of the metal of the sleeve will be uniform from each side of the midpoint. Alternatively, the plungers may be pressed outwardly by springs. A passage 28 allows the escape of air from the space between the die and the sleeve. On raising the upper die part, the plungers serve to grip the work and lift it off the lower die part. The work is then released by relaxing the fluid pressure behind the plungers.

Title: Improvements in or relating to internal-combustion engine valve apparatus
IPC: F01L7/04
Filed: 1939-09-16
Abstract: 532,756. Valves; lubricating. DAVISONDOUGLAS CORPORATION. Sept. 1, 1939, No. 25106. Convention date, Sept. 16, 1938. [Classes 7 (ii) and 7 (vi)] A rotary valve is provided with lubricating- passages arranged so that the action of centrifugal force on the oil flowing through the passages produces a liquid seal opposing the escape of gases past the valve. Fig. 1 shows a valve 31, 32 driven by means of a gear ring 29 attached thereto, oil supplied at 63 flowing from a groove 9, through inclined passages 115 in the valve in which centrifugal force takes effect, and passages 16 in the gear ring, to another groove 114, from which it escapes past a bearing-ring 40 and passages 12, to an exit chamber 8 in which the driving-pinion 20 is mounted. Further oil escapes past an upper bearing-ring 50 and passage 12 to the chamber 8, the flow past both bearing-rings being assisted by centrifugal force, and escape of gases past packing-rings 51, 52 being prevented by the film of oil retained in the passages. The casing ports are formed in a cylindrical member 37 having an upward projection extending well up into the valve port 31 to a bevelled edge 1, thereby forming a hair-pin passage for gases tending to escape past the outer rings 52. The lower part 32 of the valve is slotted axially to form the port, and is also slit circumferentially at 32a to increase its flexibility. According to the Specification as open to inspection under Sect. 91, the valve may be expanded by peening at various points, and in a multicylinder engine, the inlet passages may be arranged tangentially, so as to cause a whirling of the charge within the valve, and the direction of rotation of the several valves may be arranged to assist this whirling. This subject-matter does not appear in the Specification as accepted.

Abstract: 265,917. Siemens & Halske Akt.- Ges. Feb. 9, 1926, [Convention date]. Addition to 262,395. Follow-up control systems; indicators, applications of; controllers with combinations of resistances.-In controlling motors by a Wheatstone bridge arrangement of resistances so as to move distant apparatus proportionally to the joint effect of two instruments, the resistance w at the transmitter end is traversed by a sliding contact kg1 operated by one of the instruments, and also by a pair of sliding contacts kg3, kg4 which are united by a rigid insulating member so as to move together and are operated by the second instrument. The disposition is such that the total resistance included between kg3, kg4 is constant, and thus the effect on the neutral arm in connection with kg1 is proportional to the sum or difference of the separate displacements. More complicated arrangements are described in which the motor travel is a function of three or more transmitter or instrumental displacements. The Specification also describes an arrangement in which a logarithmic distribution of stationary resistance in the track of the sliding contacts is used to obtain movements proportional to the product of two variables. Indicating voltmeters connected between stationary and movable points of the bridge resistances may be used to check the positions of the transmitter or receiver contacts.

Title: A process for the utilisation of alcoholic fermentation in order to form large quantities of glycerine by the use of sulphurous acid
IPC: C12P7/20
Filed: 1926-10-13
Abstract: 282,917. Barbet, E. A. Oct. 13, 1926. Glycerine, obtaining. - In the production of glycerine by fermentation of sugar small doses of sulphurous acid are used in place of the large doses of sodium sulphite or other reducing agent. For example, molasses diluted to a density of 1.070-1.180 is treated with 2 grams of sulphur dioxide per litre, preferably without addition of sulphuric acid, and is added to molasses being fermented by yeast when the density in the fermentation vat has fallen to about 1.034. Further doses are added as required to maintain the density at about 1.034. The process may also be applied to the fermentation of all distillable wines, beetroot, grain, potato, agave wines, grape wines, and cider, the density being maintained below 1.034. The yield from beetroot molasses is greater than that given by Pasteur as a mean, and is attributable to the large proportion of organic salts present acting in the same manner as sodium sulphite or carbonate. In the fermentation of beetroot juices organic potassium salts are therefore added, pre. ferably from the concentrated beetroot vinasses.
