Abstract: 253,860. Stuber, A. June 16, 1925, [Convention date]. Void [Published under Sect. 91 of the Acts]. Dobbies.-The driving lever 4 is driven by a rod 14 adjustably attached to a pivoted slotted guide 12. which is turned about its axis 13 by a roller 9 sliding in the guide 12 and also in a fixed but adjustable guide 11 having a central curved part and two straight parts 11<1>. The roller 9 is operated by a rod 10, a slider 8, a rod 7 and a crank on the cam shaft. The guide 12 is turned until it is alined with a straight part 11' of the guide 11, after which the roller 9 slides in the guides 11, 12 without turning the guide 12 thus producing a dwell. A modification is described wherein the rod 7 operates a two-armed lever furnished with a bowl engaging a shaped guide on a lever on a shaft furnished with a lever adjustably connected to the dobby driving-lever.

Title: A process for the production of polyurethane plastics
IPC: C08G18/12
Filed: 1959-09-24
Abstract: A process of producing polyurethane plastics comprises preparing a storage stable intermediate in a first step by reacting (a) a polyhydroxyl compound with a molecular weight greater than 1000, (b) water or an organic compound with at least two aliphatically bonded hydroxyl and/or amino groups and a molecular weight below 500 and (c) a less than chemically equivalent quantity of an organic diisocyanate and curing this storage stable intermediate in a second step by mixing it with from 5 to 80% by weight, based on the weight of the intermediate, of an organic compound containing at least two aliphatically bonded hydroxyl and/or amino groups in the molecule and with a molecular weight below 500, and an organic polyisocyanate in an excess of 20 to 200 mol. per cent above that required to react with all the hydroxyl and/or amino groups present.  As polyhydroxy-compounds, a number of polyhydric polythioethers, polyester amides and polyacetals are specified.  Among the compounds listed for preparing the polyesters are aromatic, sulphur-containing or unsaturated acids.  Examples of compounds of M.W. below 500 are reaction products of urea with ethylene oxide, oxazolidone with ethanolamine, diethanolamine with potassium cyanate and glycols containing urethane, carbonamide, ester or tertiary amino groups as well as the more usual amino, carboxylic and hydroxy compounds.  The di- and poly-isocyanates listed include compounds with sulphone and azo linkages.  The storage-stable intermediate can be prepared using all the reactants together or by reacting various mixtures of them in stages.  The final products can be used in articles for damping vibrations, handles of pneumatic drilling equipment, bearing boxes, gear wheels, buffers and couplings.  In Example (1) a storage-stable intermediate is prepared by reacting an adipic acid glycol polyester with p-phenylene diisocyanate and reacting the product with 1,4-butane-diol.  Into the intermediate are incorporated on a rolling mill (1B) p-phenylene-betadihydroxyethyl ether and dimeric tolylene diisocyanate; and the mixture is then moulded under heat and pressure.  In other examples the reactants used in similar processes are (2) a polythioether from thiodiglycol and triethylene glycol, tolylene diisocyanate, p-phenylene dihydroxyethyl ether and 4,41-diisocyanato-3,31-dimethyl-diphenyl urea; (3) adipic acid-diethylene glycol polyester, water and butene-1,4-diol, tolylene diisocyanate, o,o1-dichlorobenzidine and 4,41-diphenylmethane diisocyanate; (4) adipic acid/glycol polyester, tolylene diisocyanate, dichlorobenzidine, 1,5-naphthalene dihydroxyethyl ether and tolylene diisocyanate; (5) polyalkylene ether, water and butenediol (mixed), tolylene diisocyanate, p-phenylene dihydroxyethyl ether and p-phenylene diisocyanate; (6) adipic acid/glycol polyester diphenylmethane diisocyanate, and either 1,4-butanediol and dimeric tolylene diisocyanate or 3,31-dichloro-4,41-diamino-diphenylmethane and dimeric tolylene diisocyanate.

Abstract: 341,971. Permutation locks. COOK, J., Somerset House, Somerset Road, Lain. don, Essex. Oct. 25, 1929, No. 32525. [Class 44.] A drawer &c. lock has reversible elements operated selectively and with means for restoring wrongly operated elements to inoperative position. The drawer 11 is locked by the engagement of hook-like heads 21 of members 19 with the shoulder 26. The elements are arranged so that some have the hookheads directed downwardly, and some upwardly. Operation of the former only is required for release to lift the heads clear of the shoulder 26. If the others are operated, these heads engage the shoulder 25 and lock the drawer. The elements are operated by a pin entering holes 31 to push forward blocks 29 to engage lifting members 27. To restore wrongly operated elements to inoperative positions, the pin is inserted into the hole 40, to push forward a bar 39 which tilts the pivoted bar 41 to actuate a bar 38. This moves all the lifting members 27 to inoperative position. To prevent operation of the pushers 29 unless the drawer is properly closed, a catch 34 pivoted at 35 drops into engagement with the shoulders 33 until tilted out of their path by the complete closing of the drawer.

In a gas-blast switch having a plurality of series-connected circuit interrupters and a corresponding plurality of switching resistors, each switching resistor comprises a series of resistor elements and a series of pressuresensitive adjustable spark-gap electrode structures, each electrode structure being between an adjacent pair of resistor elements. A rise of pressure in the resistor assembly immediately after separation of the interrupter contacts is effective to increase the spacing of the electrodes to promote extinction of interrupter current diverted through the resistors. Fig. 2 shows one construction of the electrode assemblies in which the electrodes 11a, 22 are biased together by a spring 23 and are separated by gas pressure acting on a bellows 21, a stop 22a limiting the travel of the moving electrode 22. In Fig. 7, the moving electrode is provided by the domed end of a cylinder 54 movable with respect to a fixed piston 55 against the bias of a spring 60 when gas pressure is applied to the interior of the container 59. A rubber pistonring 56 permits relative movement between the cylinder and piston without any slip of the ring.
