Title: Improvements in or relating to moulding hollow glass articles
IPC: C03B11/10
Filed: 1958-11-17
Abstract: 890,690. Moulding glass. PlLKINGTON BROS. Ltd., and WILCOCK, J. E. Oct. 30, 1959 [Nov. 17, 1958], No. 36965/58. Class 56. When moulding a glass article comprising contiguous inner and outer parts, one of which, particularly the inner, is thinner than the other, the two parts are moulded by separate pressure members, that for the thinner part being closed before the other and, when the thin part has cooled sufficiently to hold its shape, removed first, the other pressure member being held in position until the thicker part has cooled sufficiently to hold its shape. In the form shown, a main cylinder 8 contains a piston 10, the piston rod 11 of which carries the auxiliary cylinder 9 to which is attached, by rods 32, a pressure member 4 which is concentric with a pressure member 3 supported from the piston rod 26 of the piston 25 of the cylinder 9. Valves 18, 24 control the supply of air from a line 19 to either end of either cylinder. Stop members 39 carried by the plate 28 attached to the pressure member 3 and bolts 37 carried by the pressure member 4 limit the relative movement of the members 3 and 4, while screws 41 on the plate 28 limit the downward movement of the member 3 relatively to the mould 1. A charge of glass 2 is placed in the mould 1. When starting to mould an insulator, for example, the piston 10 is at the top of the cylinder 8 and the piston 25 at the bottom of the cylinder 9. Air is admitted to the cylinder 8 to push the piston down. The member 3 enters the mould 1 first and shapes the inner, thinner part of the insulator. Air is then admitted to the cylinder 9 to lower it relatively to the piston 25 bringing the member 4 into the mould 1. The movement of the piston 25 is continued, to maintain the member 4 in the mould while the outer, thicker part of the insulator hardens, as air is admitted to the cylinder 8 to lift the piston 10 and the pressure member 3 and so prevent cracking as the thinner part of the insulator contracts: As the piston continues to rise the member 4 is also retracted. The member 3 is cooled by fluid circulated through channels 30 from a pipe 31.

Title: Improvements in gramophone records and the method of manufacture
Filed: 1928-12-15
Abstract: 327,134. Thornton, J. E. Dec. 15, 1928. Addition to 326,765. Compound sheet materials. - Gramophone records are made by thoroughly impregnating a sheet of absorbent paper material or felt with a solution of cellulose xanthate, treating the impregnated sheet with an agent which precipitates cellulose from the xanthate, and, after drying, impressing sound-grooves in the cellulose. The paper material for the base may be pulp board, blotting paper or filter paper, one or more layers of which may be used. Felt or thick pulp board is suitable for rigid records. Barytes, dyes. gums, or resins &c. may be added to the cellnlose xanthate used. Impregnation of the base may be effected by suspending discs of the material in vats of the hot solution, which vats may be closed so that pressure can be applied; or a continuous web may be passed through the liquid and squeezed between rolls as it merges from the vat. After impregnation, the web or discs are passed through brine, acid, or other suitable precipitant. The cellulose may be chemically hardened, or treated with a flexing agent as described in the parent Specification. A two-ply disc may be made by pressing together two impregnated layers, preferably before precipitation of the cellulose from the xanthate solution. Specification 326,766 is referred to.

Title: Aminoacid esters
Filed: 1954-12-22
Abstract: The invention comprises compounds of the formula R1OOC-CHR-N(CH2CH2Cl)2 and their acid addition salts, wherein R is hydrogen or a C1 to C4 alkyl group and R1 is a C1 to C4 alkyl group. Such compounds are obtained by condensing an alcohol of formula R1OH with a compound having the general formula Y-CHR-N(CH2CH2Cl)2 where Y is a carboxyl radical or a derivative thereof capable of forming a carboxylic acid ester group with an intermediate or concurrent hydrolysis reaction when Y is a derivative of a carboxyl group.  The derivative may be a carboxylic acid amide, nitrile or carboxylic acid halide.  The amides and acids may be obtained by the methods of Specifications 767,679 and 767,680.  In Examples (1), (2) and (4) N-bis-(b -chloroethyl)-glycine ethyl ester hydrochloride is prepared by heating N - bis - (b  - chloroethyl) - glycinenitrile, N - bis - (b  - chloroethyl) - glycine hydrochloride, and N - bis - (b  - chloroethyl)-glycineamide hydrochloride respectively, with alcoholic hydrochloric acid; (3) N-bis-(b -chloroethyl)-alanine ethyl ester is prepared by heating N - bis - (b  - chloroethyl) - alanineamide with alcoholic hydrochloric acid.  An amide or nitrile may also be first hydrolysed to the acid, which, with or without isolation, is converted to the ester.

By suitably choosing numbers and speeds it is possible to distribute the crosses over the wales as required and pro, duce an entirely non-laddering fabric. The gears 8, 10, 11, 13, 17, 18 are so arranged that the' upper cam ring 5, the lower guide ring 26, and the bobbins 21 revolve together in one direction while the lower cam ring 3, the upper guide ring 39, and the bobbins 21<1> revolve together in the opposite direction.

Title: 2-imino-thiazoline derivatives and their preparation
IPC: C07D417/06
Filed: 1964-09-14
Abstract: The invention comprises 2-imino-thiazoline derivatives of the formula <FORM:1081283/C2/1> wherein X is an oxygen or sulphur atom, Y is a -CO-, -CH(OH)- or -CH(O-CO-C1- 6 alkyl)-radical, and Z is a C1- 6 alkyl, C1- 6 alkoxy or cyclopropyl radical and the therapeutically active non-toxic acid-addition salts thereof.  The compounds where Y is a -CO-radical are prepared from 2-imino-3-[(2-thienyl-carbonyl) - methyl] - thiazoline and 2-imino-3-[(2 - furyl - carbonyl) - methyl] - thiazoline; acylation of these compounds with an appropriate acylating agent, e.g. an anhydride or halide of a C2- 7 aliphatic acid or a cyclopropyl carboxylic acid halide, gives the compounds where R is a C1- 6 alkyl or cyclopropyl radical, and reaction with a C1- 6 alkyl haloformate gives the compounds where R is a C1- 6 alkoxy radical. Alternatively, the compounds where Y is a -CO- radical are prepared by reaction of a halomethyl - 2 - thienyl - ketone or a halomethyl - 2 - furyl - ketone with a 2 - (Z - CO - amino)-thiazole (resonant form:  2 - (Z - CO - imino)- thiazole). The compounds where Y is a -CH(OH)- radical are prepared by reducing the corresponding compounds where Y is a -CO- radical with, for example, an alkali metal borohydride. The compounds where Y is a -CH(O-CO-C1- 6 alkyl)- radical are prepared by acylating with, for example, an anhydride of a C2- 7 aliphatic acid, the corresponding compounds where Y is a -CH(OH)- radical. Alternatively, these compounds may be prepared by acylating 2-imino-3-[2-hydroxy-2 - (2 - thienyl) - ethyl] - thiozoline or 2 - imino-3 - [2 - hydroxy - 2 - (2 furyl) - ethyl] - thiazoline with, for example, an anhydride or halide of a C2- 7 aliphatic acid, in which case Z and the alkyl moiety of Y are identical.  2 - Imino - 3 - [(2 - thienyl) - carbonyl)-methyl]-thiazoline and 2 - imino - 3 - [(2 - furyl)-carbonyl)-methyl]-thiazoline are prepared by heating 2-imino-thiazoline with a halomethyl-2-thienyl-ketone or a halomethyl-2-furyl-ketone, respectively, and liberating the free base from the hydrohalide salt by conventional methods.  2 - Imino - 3 - [2 - hydroxy - 2 - (2 - thienyl)-ethyl] - thiazoline and 2 - imino - 3 - [2-hydroxy-2 - (2 - furyl) - ethyl] -thiazoline by the alkali metal borohydride reduction of the respective 2 - imino - 3 - [(2 - thienyl)-carbonyl) - methyl] - thiazoline and 2 - imino-3-[(2 - furyl) - carbonyl) - methyl] - thiazoline compounds.
