Abstract: 523,237. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO.. Ltd. Dec. 29, 1938. No. 37741. Convention date. Dec. 29, 1937. [Class 38 (iii)] A synchronous motor is started with a lowresistance 6 initially across its field 3, at an intermediate stage the field is excited through a resistance 24 higher in value than the resistance 6, and finally the resistance 24 is shorted. Closure of switch 4 causes relay 12 to lift due to high-frequency slip current being taken from resistance 6 through half-wave rectifier 13. Lifting of relay 12 causes lifting of relays 14, 15, and consequential lifting of relay 20, and maintenance of itself although relay 20 lifts. When the frequency of the slip-current decreases sufficiently, relay 12 drops, as described in Specification 384,567, and a time interval thereafter relay 14 drops and energizes relay 10 over relay 20 to change over from resistance 6 to resistance 24. Relays 10 and 11 maintain themselves over auxiliary contacts of the switch 4, and relay 20 drops a time interval after both relays 14, 15 have dropped. Specification 482,463 also is referred to.

Abstract: 1,159,933. Catalytic isomerization of alkylene oxides. RUMANIA, MINISTRY OF INDUSTRIAL CHEMICALS. 24 Aug., 1966, No. 37914/66. Heading C2C. Isomerization of a 1,2-alkylene oxide containing 3 to 5 carbon atoms in the molecule to the corresponding unsaturated alcohol is effected by passing the alkylene oxide at a temperature between 200‹ and 350‹ through a layer of solid granular catalyst suspended in the vapour stream so that the catalyst serves as a fluidized bed or as a solid in pneumatic transport state. The preferred catalyst is lithium ortho phosphate, which contains 0 to 50% by weight of specified inert fillers and is in the form of grains of 0À1 to 1 mm. in diameter. According to a further embodiment of the invention the activity of resin-contaminated catalyst may be regenerated either by raising the temperature of the catalyst to 40-50‹ C. above the normal operating temperature for 15 to 45 minutes at the completion of specified operating periods or by cycling a solvent for the contaminating resins upward through the catalyst under conditions which maintain the solvent in the liquid state and at a flow rate which does not carry the catalyst out of the reactor. The process may be carried out in a vertical cylindrical reactor wherein the catalyst is in the form of a single layer, layer ranges or a layer provided with baffles at various levels. The isomerization of propylene oxide to alkyl alcohol is described.

Abstract: 857,974. Finishing yarns. SCRAGG & SONS Ltd., E. Sept. 11, 1959 [Nov. 25, 1958], No. 37922/58. Class 120(3). Thermoplastic yarn, which is to be crimped to impart modified stretch and bulk properties thereto, is fed by rollers into a stuffing-box crimping chamber. Yarn, in which crimp is "set" by heating in the box or subsequently, is continuously discharged from the box into, and is collected from, a circular channel at two different points between which the yarn is cooled to "fix" the crimp. The channel is formed in a drum between which and the box relative motion occurs. As shown, yarn is fed at 1 by rollers into a crimping chamber 12 formed by a metal tube one end of which directs crimped yarn into a covered channel 13 in the face of a drum 14 which is rotated, by the pressure of discharging yarn or a direct drive (not shown), against an adjustable brake 17. Heat may be adjustably applied to the tube by an electric heater 16 or to that part of the drum which receives yarn from the tube by inductive or radiant means (not shown) and the temperature may be automatically stabilised. The rollers are driven from a shaft 8 (which may serve a series of machines) through gears 4, 5 and a belt 6 which is tensioned against a driving pulley 7 by an idler pulley 9 mounted on a bell-crank lever 10 one arm of which is tensioned by a spring 11. When the yarn has travelled about 180 degrees of the path permitted by the drum, it is withdrawn by rollers, through a tensioner, at a predetermined rate and wound, Fig. 1 (not shown). The collected yarn may be further heated (to reduce stretch and enhance bulk) as by passage over or through a heated surface or tube the temperature of which is slightly higher than that used for crimping. The drum may be stationary and the rest of the crimping apparatus moved therearound.
