Patent GB-865739-A (GB)
Title: Polyurethane casting compositions
IPC: C08G18/42
Filed: 1959-03-18
Abstract: The invention comprises the reaction product of a liquid reaction mixture comprising a polyester prepared from at least one dicarboxylic acid and at least one glycol, the polyester having a molecular weight of from 1,500 to 2,500, a hydroxyl number of from 45 to 75 and an acid number not greater than 5, ortho dichlorobenzidine and 3, 31-dimethyl 4, 41-diphenylene diisocyanate, the diisocyanate being in a molar excess of at least 10% over the combined molecular amount of the dichlorobenzidine and the polyester.  The polyester and diisocyanate may first be reacted at 100 DEG  to 140 DEG C., the dichlorobenzene is then mixed in, and the mixture is poured into a mould where it cures, advantageously, although not necessarily, with heating.  Succinic, glutaric, adipic, pimelic, suberic, azelaic and sebacic acids and ethylene, propylene, butylene, pentamethylene and hexamethylene glycols are specified for the preparation of the polyesters.  Preferably 0,10 to 0,8 mols of odichlorobenzidine and 1,25 to 2 mols of the diisocyanate per mol of polyester are employed. Particularly preferred are the polyesters from adipic acid and a mixture of glycols containing approximately 80 mol per cent of ethylene glycol and 20 mol per cent of propylene glycol, in the molecular weight range of about 2,000 and having an acid number not greater than 2.  Comparison results (smear point) of a product in accordance with the invention and products variously from 4, 41-diphenylene methane diisocyanate, m-phenylene diisocyanate, 1, 5-naphthalene diisocyanate, and (as cross-linking agents) o-dichlorobenzidine, methylene bis-o-chloroaniline and 1,4-butanediol, are given.

Title: Process for the manufacture of polyethylene terephthalate of high molecular weight
IPC: C08G63/82
Filed: 1958-03-24
Abstract: High molecular weight polyethylene terephthalate is made from a low polymer thereof by (a) heating a molten layer of the low polymer having a thickness of more than 1 cm. and less than 18 cm. from about 240 DEG C. up to about 290 DEG C. in not more than about 20 minutes, while stirring under reduced pressure; (b) raising the temperature in about 5 to 10 minutes to a temperature in the range of 300 DEG -320 DEG C. and (c) maintaining a temperature in this range for at most 20 minutes to produce a polyester having an intrinsic viscosity of greater than 0,6.  Polycondensation is effected in the presence of a catalyst consisting of a metal compound in which the metal is bound to oxygen and belongs to one of the Groups Ia, IIa, IIIa, IVa, Va, Ib, IIb, VIb, VIIb or VIIIb of Mendeleeff's Table, e.g. an oxide, hydroxide, alcoholate, phenolate, acetate, propionate, benzoate, phthalate, terephthalate, salicylate or naphthenate of such a metal. Specified catalysts are zinc acetate (alone or in admixture with antimony oxide), antimony acetate, manganese acetate, cobalt acetate, cadmium acetate or antimony potassium tartrate.  Triaryl phosphites may additionally be added to the mixture undergoing polycondensation. In examples a low polymer made by reacting dimethyl terephthalate with ethylene glycol was polycondensed by the above process.

Title: Improvements relating to the pyrolysis of gaseous paraffins
IPC: C07C2/76
Filed: 1940-05-30
Abstract: Methane is pyrolysed to an aromatic liquid consisting mainly of benzene by treatment at a temperature above 700 DEG  C., but below 1050 DEG  C., in the presence of iodine, or an iodine compound for a reaction time of the order of 60 seconds.  According to the examples, a gas mainly comprising methane is passed in admixture with iodine through a quartz tube maintained at temperatures of 800 DEG , 850 DEG and 950 DEG  C. respectively, the speed being such that the duration of the gas in the tube is 58 seconds.  After passing through a tar trap and over soda lime, the gases are led into a condenser cooled with solid carbon dioxide in which the benzene collects.

Title: A process for the fixation of creases and pleats in wool-containing fabrics
IPC: D06M13/152
Filed: 1955-04-01
Abstract: Textile fabrics containing wool are treated at room temperature with a solution of an acidic organic substance, e.g. thioglycollic acid, chloracetic acid, phenol or cresol, which is then completely removed by washing, and the fabrics are dried and set in a desired shape, e.g. in pleats or creases, by ironing or pressing at elevated temperature.  The fabric may be in the form of a garment, or may be made into a garment after the liquid treatment and before shape-setting.  The acidic organic compound may be dissolved in water or in an organic solvent, e.g. kerosene.  In an example the solvent is a solution of benzene in a petroleum fraction boiling between 160 DEG  and 260 DEG  C.  The examples describe the treatment of fabrics of wool mixed with polyamide, polyester and polyacrylonitrile fibres.

Title: Improvements in rotary duplicating machines
IPC: B41L19/00
Filed: 1925-04-09
Abstract: 253,283. Ramdor, L., and Deutsche Post - und Eisenbahn - Verkehrswesen Akt.-Ges. (Dapagtfubag). April 9, 1925. Stencilling; stopping and tripping arrangements.-A rotary stencil or type duplicator is constructed so as to lock the printing-cylinder automatically if a sheet is not fed or is fed too late, and the printing-cylinder is prevented from moving backwards beyond the permissible point by a pawl which engages a notch in the cylinder, so that impressions cannot be printed unless the sheet is present. The sheets are fed by rollers a, b, the roller b being lowered by a lever and cam d on the printing-cylinder to feed the sheets to the machine. A feeler f rises from a groove in the roller a when a cam l permits, and, if no sheet is being fed, a pawl g is raised by a spring q and engages a ratchet wheel h, which is connected to the printing-cylinder by an elastic connection i or by springs k. The cylinder is thus prevented from rotation by the pawl g, or, if desired, a brake may replace this pawl. The pawl 9 is connected by a link p to a lever arm f<1> on the shaft of the feeler f. When the rollers a, b are apart, the pawl g is held depressed by a lever arm n, which is operated by the cam l to release a pin o on the arm f<1> from the restraining action of the lever n. If the spring q fails to raise the pawl g, it is raised by the action of the lever n on the pin o. The impression cylinder is mounted in eccentric bearings fitted with a ring r for operating them, and provided with a spring catch to hold the bearings in operative or inoperative position. When the ring r is moved counterclockwise to trip the impression cylinder for inking-up purposes, a lug p on the ring r engages the pin o and so prevents the pawl g from locking the printing-cylinder as it rotates to allow inking of the stencil &c.

Title: Improvements in and relating to luminairs
IPC: F21V5/00
Filed: 1937-04-05
Abstract: 474,141. Street &c. lamps. HOLOPHANE, Ltd. (Rolph, T. W.) April 5, 1937, No. 9623. [Class 75 (ii)] In a street or like lamp in which a symmetrical or asymmetrical reflector 13 above the light source 12 redistributes the light in vertical planes and directs it downwardly into an opentopped bowl or band refractor 14 which surrounds the light source and redistributes the light in horizontal planes, the refractor is supplemented by an internal deflector which intercepts some of the direct and reflected light and diverts it away from the eclipsed portion of the refractor to augment the asymmetrical distribution of the light. The deflector may be prismatic and formed on one or both surfaces with refracting prisms arranged vertically and/or horizontally, diagonally, or in concentric arcs, or it may be made reflecting by using reflecting prisms or specular or diffuse reflecting surfaces such as polished metal, silvered glass, porcelain enamel, opal glass, or plastic material. When the deflector is opaque it may be spaced away from the refractor so that some direct or reflected light may pass behind the deflector to illuminate the eclipsed portion of the refractor. The deflector may be flat or curved, and it may be disposed vertically or inclined. A pair of similar or dissimilar deflectors may be arranged one on each side of the light source. Fig. 2 shows a deflector 17 with vertical refracting prisms fitted into a slot 27 in the refractor 14 so as to augment the lateral deviation of the light. Fig. 4 shows a deflector 32 with horizontal refracting prisms to augment the downward deviation of the light. Fig. 8 shows a cylindrical deflector 40 formed with reflecting prisms for directing the light towards the opposite side of the refractor. Fig. 10 shows a pair of deflectors 49, 50 fitted into an elliptical refractor 14.
