Abstract: 595,304. Torque-indicators for aeroengines. NICHOLSON, R., and RUSSELL, W. M. July 25, 1944, No. 14169. [Classes 4 and 114] [Also in Group XXVII] In order to furnish the pilot of an aircraft with an indication when an engine fails the engine mounting has a limited degree of torsional flexibility, and an electric microswitch which controls an indicator is operatively connected to one of two parts of the installation which move relatively to one another under the torque-reaction of the engine. In the form shown, a rubber pad 4 is interposed between each of the engine feet 3 and the mounting 1 to provide torsional flexibility, one of the feet carrying the electric micro-switch G of which the operating pin 7 engages an adjustable abutment 8. Normally the switch is open, but in the event of engine failure and the removal of torque, the pin 7 operates to close the switch and actuate the indicator, which may take the form of an electric lamp. The switch may be arranged to close only when the propeller is rotated by the airstream flowing over it, following engine failure. Where feathering control means are provided, the switch 6 may be arranged in series with the feathering switch or may be arranged to operate it through a relay, so as to feather the propeller blades automatically when the engine ceases to function.

Abstract: 980, 331. Fabrics. SHAWINIGAN RESINS CORPORATION. April 21, 1961 [May 12, 1960], No. 14410/61. Heading D1K. A process for preparing weftless tape comprises juxtaposing in side by side parallel relationship a plurality of twisted paper strands, applying a coating of an aqueous dispersion comprising 20 to 50% polyvinyl acetal by weight of the dispersion, and 35 to 50% of a plasticizer by weight of the polyvinyl acetal. A preferred ratio of p.v. acetal to paper is 7 to 8% by weight. Suitable polyvinyl acetals may be obtained by reacting polyvinyl alcohol or a partially hydrolysed polyvinyl ester with an aldehyde such as butyraldehyde, formaldehyde, acetaldehyde, propionaldehyde, and benzaldehyde. The preferred p.v. acetal is polyvinyl butyral. Suitable plasticizers are phthalate esters, phosphate esters, citrate esters and chlorinated biphenyls; e.g. dibutyl phthalate, butyl ricinoleate, and tri-(2-ethylhexyl) phosphate. The dispersion may be prepared by use of a soap-type emulsifying agent comprising oleic acid and potassium hydroxide, non-ionic surfactants such as polyoxyethylene sorbitan monolamate, iso octyl phenyl polyethoxy ethanol and polypropylene glycol ethylene oxide condensates; cationic surfactants such as ethylene oxide condensation products of primary fatty amines; and anionic surfactants such as dioctyl ester of sodium sulphosuccinic acid and the sodium salt of condensed sulphonic acid. The dispersion may comprise thickening agents such as the sodium salt of carboxymethyl cellulose, methyl cellulose and hydroxyethyl cellulose; borated alginate; guar gum, methylated guar gum and gum arabic. The tape may be made as shown in Fig. 2. Twisted paper strands 1 are fed from bobbins 2 to comb 3 whereby they are brought together in juxtaposed side-by-side parallel relationship. The strands then pass over adjustment roll 5 and application roll 6 whose lower part dips into adhesive 7 in bath 8. The strands coated with adhesive pass through guiding element 9 and over a series of heated drums 10 whereon the adhesive is dried and the strands bonded together and the dried tape then passes through tension rolls 11, which draw the strands and tape through the stages of the process, and is wound up on drum 12. Six specific examples are described. Specification 641,653 is referred to.

Title: Improvements in or relating to the removal of acetylene from air
IPC: B01D53/46
Filed: 1958-05-06
Abstract: Acetylene is removed from admixtures with air by conversion to carbon oxides and water by passage over a catalyst which contains palladium as at least the major part of the catalytically active metal, at 100-200 DEG C. and atmospheric-1000 p.s.ig. pressure.  The catalyst may comprise 0.1-2% wt. of palladium alone or in admixture with minor portions of other platinum group metals, e.g. Rh, Pt, Ru, Os, and Zr, supported on activated alumina, silica gel, or alumina silica.  The use of 0.2-1% wt. Pd supported on activated alumina is preferred. The process is particularly directed to the purification of air before entry into a liquid air production plant (see Group XXVIII). Air, containing for example p  up to 15% vol. water and 0.1-50 parts/million of acetylene may be passed over the supported catalyst at say 50 p.s.i.g. and a space velocity of 3000-100,000 hr-1 particularly 5000-50,000 hr-1.  At pressures in excess of 50 p.s.i.g. the necessary temperatures are produced by the heat of compression, the addition of a small amount of hydrogen or hydrogen/nitrogen mixture, however, to the air stream immediately prior to the catalyst bed, particularly at start-up of the purification process, to produce heat by catalytic combustion is referred to. Rises in temperature of 82 DEG C. for each per cent of hydrogen added may be obtained in this manner.
