Filed: 1971-01-18
Abstract: 1298312 Warp stop motions CONTRAVES AG 18 Jan 1971 [27 Feb 1970] 2433/71 Heading D1E A defective warp thread allows a dropper 4 to fall and interrupt a current of air to stop the loom. The ends of the droppers 4 enter a channel 1 having air inlet tubes 20 with discharge openings 25 which cause air to pass along the channel 1 to inlet openings 24 of adjacent air supply tubes 20. The tubes 20 also have openings 28 allowing air to pass along sensing tubes 5 which discharge through openings 26 into adjacent tubes 20 which have partition walls 21 with openings 27 aligned with the openings 28, 26. In use, air in the tubes 20 passes along the dropper channels 1 and thence through the openings 24 of adjacent tubes 20 to deflect downwardly air passing through the openings 26, 27. When a dropper falls the air flow through the openings 24 is interrupted and air no longer deflects the air through the openings 26, 27, which air jets impinge on each other causing a difference in pressure in the sensing tubes 5 which is effective to stop the loom. (For Figures see next page)

Title: Improvements in or relating to lubricating devices
IPC: F16N13/16
Filed: 1947-01-27
Abstract: 626,093. Lubricators. CLAYTON DEWANDRE CO., Ltd., and EDGE, S. H. Jan. 27, 1947, No. 2498. [Class 12 (iii)] [Also in Group XXVIII] In a multiple delivery lubricator, operation of a piston 4 in a cylinder 1 causes simultaneous movement of a number of plungers 8 to expel lubricant from a reservoir 3 into radial ports 23 each communicating with a separate component requiring periodical lubrication. Application of a vacuum to the left-hand side of piston 4 causes movement thereof to the left and corresponding movement of the plungers 8 through the engagement of plunger heads 7 with a plate 6 secured to the end of the pistonrod 5. The movement of the plungers cuts off the supply of lubricant from ports 18 to the passages 19, and the ends of the rods 8 entering passages 19 force the lubricant past non-return valves 21 to the ports 23. On release of the vacuum, piston 4 and plungers 8 return to their original positions under the action of springs 11 acting on plunger heads 7. The stroke of the piston 4 may be adjusted by member 10 mounted in the cover 9. In a modification, the piston is mounted adjacent the plate 6 and is operated by air pressure. In an automobile, the cylinder 1 may be operatively connected with the braking system. In other applications a mechanically-driven valve is interposed between the source of pressure or vacuum and lubricator cylinder 1.

Patent GB-815852-A (GB)
Title: Polyesters of dicarboxylic acids
IPC: C08G63/52
Filed: 1957-01-25
Abstract: New polyesters are those of a dihydroxymethyl xylene or an oxyalkylated derivative thereof and a dicarboxylic acid (e.g. fumaric, maleic, phthalic, isophthalic or terephthalic acid or an acid of formula HOOC(CH2)nCOOM where n is 2-10).  The polyesters may be obtained by condensing the dihydroxy compound with the dicarboxylic acid or anhydride or by condensing a dihalomethyl xylene with a metal salt of the dicarboxylic acid. Polyesters derived from an unsaturated dicarboxylic acid may be copolymerized with a vinyl monomer, e.g. styrene, vinyl toluene, divinyl benzene, diallyl phthalate, vinyl acetate, diallyl succinate, diallyl itaconate, acrylamide, methacrylamide or acrylonitrile.  The polyester may be mixed with other polyesters derived from phthalic or adipic acid and ethylene glycol, propylene glycol, diethylene glycol, glycerol or pentaerythritol. Polyurethanes are obtained by reacting a diisocyanate with the polyesters alone or mixed with the other polyesters.  In examples: (1) and (2) a polyester is obtained by reacting dichloromethyl xylene and sodium fumarate or sodium hydrogen fumarate in presence of dimethyl formamide.  (3) A polyester is made by reacting dichloromethyl xylene with sodium adipate in presence of dimethyl formamide or water.  (5) A polyester made by reacting dihydroxymethyl xylene with maleic anhydride in presence of xylene is copolymerized with styrene in presence of benzoyl peroxide.  (7) A polyester made by reacting di-(beta-hydroxyethoxymethyl)-xylene with maleic anhydride in presence of xylene is copolymerized with styrene in presence of benzoyl peroxide.  (8) A polyester is obtained by reacting dihydroxymethyl xylene, ethylene glycol and maleic anhydride in presence of xylene.  It is stabilized with hydroquinone or t-butyl catechol and may be polymerized alone or with styrene.  (9) A polyester is obtained by reacting dihydroxymethyl xylene, di-(betahydroxyethoxymethyl) xylene and adipic acid in presence of xylene.  It is converted into a polyurethane foam by mixing with tolylene diisocyanate, N-methyl morpholine, an alkaryl polyether sulphonate and water.ALSO:4,6-Bis (chloromethyl)m-xylene is made by heating a mixture of m-xylene, aqueous formaldehyde solution, hydrochloric acid and zinc chloride (catalyst) whilst bubbling hydrogen chloride gas through the mixture and then washing the resulting white solid with water and crystallizing it from heptane. A dihydroxymethylxylene is made from a dichloromethylxylene by refluxing the latter with aqueous sodium acetate solution, adding sodium hydroxide and continuing the heating.  A di (betahydroxyethoxymethyl)-xylene is made from a dichloromethyl xylene by heating the latter with a solution of sodium hydroxide in ethylene glycol, filtering off precipitated sodium chloride, stripping off excess glycol and filtering and distilling the residue.  The products are condensed with dicarboxylic acids or anhydrides or salts thereof to make polyesters (see Group IV (a)).

[Also in Division A3] An inertia reel comprises a shaft with an abutment face, an inertia member mounted to rotate and slide inwardly of the shaft, cam means between an abutment face on the inertia member and the abutment face on the shaft so that at a predetermined acceleration the inertia member moves inwardly against a resistance and locking means on the inertia member engages fixed co-operating means. The shaft 28 supports a strap tunnel 4 and an end flange 30 on a boss 6 on one end of the shaft. The flange has three recesses shallower at one end and the inertia member 44 slidable and rotatable on the shaft has three complementary recesses shallower at the opposite end. A spring 52 on the shaft urges the inertia member towards the flange so that balls 50 engage in the recesses. The strap tunnel supports bosses 6 and bearing plates 12 engage over the bosses and have a series of hemispherical protuberances 22. On a sudden pull being given to the strap the inertia member lags on the flange 30 and the balls 50 are moved by the shape of the recesses and force the inertia member to slide so that the protuberances 22 on the fixed bearing plate 12 engage recesses in the inertia member and arrest rotation of the shaft. The shaft also supports a boss 24 and a spring 56 is anchored in an end cap 36 and to the shaft. The end caps have bolts for securing the reel to mounting plates. In an alternative form, braking of the reel is effected by interengaging teeth on the inertia member and fixed bearing plate which is solid and fits over the shaft which is shaped to receive a pin for the strap.
