Filed: 1956-08-07
Abstract: 804,151. Finishing fabrics. SOC. RHODIACETA. Aug. 7, 1956 [Aug. 11, 1955], No. 24182/56. Class 42 (1). [Also in Group IX] A process for the production of a textile material exhibiting a relief effect comprises forming a textile material containing polyamide filaments which are wholly or partially shrunk and polyester filaments which have a shrinkage capacity greater than that of the polyamide filaments and subjecting the material to heat treatment at a temperature of at least 180 C. The material may be a plain weave fabric using in the warp sized and fully shrunk threads based on polyethylene terephthalate of 65 denier having 33 filaments and a right-hand twist of 600 turns per metre, the number of threads being 48 per cm. and in the weft, fully shrunk threads based on polyhexamethylene adipamide of 70 denier having 23 strands and a left-hand twist of 200 turns per metre and threads still capable of undergoing the greater part of their shrinkage and based on polyethylene terephthalate of 65 denier having 33 filaments and a right-hand twist of 200 turns per metre, 8 polyamide threads alternating with 8 polyester threads, and the total density being 42 threads per cm. The fabric obtained is desized in a tepid bath and preshaped on a Krantz type tenter frame with air at temperature of 220  C., the speed of travel being 12 metres per minute and the frame being adjusted to permit a 100 per cent shrinkage of the weft. After this treatment, the warp shrinkage is 4 per cent while the weft shrinkages are 2 and 14 per cent for the polyamide and polyester threads, respectively. If the fabric is dyed with acid dyestuffs, the polyester threads are not dyed and a blistered appearance is obtained. The finished fabric has a high crease resistance and may incorporate filaments which are not affected by the heat treatment.

Title: Improvements in or relating to electric circuit breakers
IPC: H01H71/16
Filed: 1931-09-01
Abstract: 374,708. Automatic circuit-breakers. WESTINGHOUSE ELECTRIC & MANUFACTURING CO., East Pittsburg, U.S.A.- (Assignees of Dorfman, H. D. ; R. F. D. 4, Mansfield. Ohio. U.S.A.) Sept. 1. 1931, No. 24531. Convention date, Sept. 6, 1930. [Class 38 (v).] The latch arm 42 of a thermallv - released circuit - breaker is retained beneath surfaces of cams 34, 35 which are pivoted at 37 between the arms of a U-shaped bracket 31 and biased to a releasing position by a spring 41. Rotation of the cams to release the arm 42 is normally prevented by the engagement between noses 47 on the cams and projections 46 on bimetallic elements 44, 45 carrying the main current. If either or both elements 44, 45 deflects sufficiently due to an overload, the corresponding cam or both cams is released, allowing the arm 42 to rise and separate the contacts 26, 27. For resetting, the cams are provided with projections 43 which are engaged by the arm 42 to rotate the cams into their latched positions, in which the projections 43 overlap. The elements 44, 45 may be located one in each pole of a multi-pole switch. Switches, quick-action.-The arm 42 is formed as an extension of a cradle 9 which is pivoted at 11 and formed with an apex 24 serving as a pivot for one end of a toggle 17, 18, the other end of which is pivoted at 22 to the movable contact-arm 19, pivoted at 21. A dead-centre spring 15 is anchored between the knee-joint 16 and handle 12, pivoted at 14, such that clockwise rotation of the handle 12 moves the spring 15 over the line of centres 16, 24, thereby closing the switch with a snap action, provided the arm 42 is latched as shown in Fig. 1. The switch can similarly be opened manually by reverse movement of the handle, or automatically on overload by the spring 15 when the arm 42 is freed.

Abstract: 754,899. Turning-gear. LAFITTE, T. J. B. Aug. 24, 1954 [Aug. 26, 1953], No. 24611/54. Class 7(5) Construction. In an engine starter drive comprising a motor shaft 1, Fig. 1, a hollow sleeve 3 fixed thereon, a driven shaft 11 having a threaded portion 18 and a pinion 17, a nut 7. engageable with the threaded portion 18, a spring 6 connecting the sleeve 3 and the nut 7, and an abutment such as the end of the shaft 1 within the sleeve, defining the idle position of the shaft 11, a second abutment, for example a shoulder 25 in the sleeve 3, is provided to positively limit the longitudinal movement of the driven shaft. Within the sleeve 3 the shaft 11 incorporates a stop 12, which in the idle position shown, abuts the end of the shaft 1 under the action of the spring 6. Within the outer end of the shaft 11 is a spring-loaded ball 15 co-operating in the position shown with a groove 22 either in the starter casing 23 or an engine bush. In a modification, a shaft 30, Fig. 4, which is an extension of shaft 1, is partly located' in a sleeve 31 that is keyed to the shaft 1 whilst the nut 36 co-operates with the threads 39 in a hollow shaft 38 slidable and rotatable on the shaft 30. On one end of shaft 38 is threaded a stop 41 between which and a flange on the sleeve 31 is disposed a spring 44. the shaft 38 and stop 41 both abutting a flange in the idle position; the outer end of the shaft 30 is supported in a ferrule 45 forming the second abutment, having a bearing 46, a spring 47 being positioned between one end of the shaft 38 and the ferrule. Operation. Upon the shaft 1, Fig. 1, being rotated a drive is imparted to the sleeve 3 and the initially stressed spring 6 whereby the nut 7 is pulled by the spring into threaded engagement with the screwed part 18 of the shaft 11, the inertia of which is increased by a weight 20 and assisted by the ball 15 in the groove 22. The shaft 11 is then urged rightwardly to mesh the pinion 17 with the engine gear 28 until the stepped part of the stop 12 abuts the shoulder 25 whereupon by screw-jack action the nut 7 screws further on the threads 18 until it abuts the reduced end 26 of the stop 12 which end forms a third abutment. The spring 6 winds itself more closely about the sleeve 3 and nut 7 as the cranking torque increases and so prevents the spring coils from frictionally contacting each other. When the engine starts the parts are automatically returned to the position shown and rebounding of the pinion is prevented by the spring 6 and the resistance offered by the nut 7 on the threads 18 and the ball 15 in the groove 22, which latter resistance is increased during rotation of the shaft 11 by a centrifugal action. The positions of the three abutments may be adjusted by washers. The modified starter drive also operates in the manner described above.

Abstract: 424,350. Spray carburetters; chargeforming devices. YEMM, E. R., 37, Hough Lane, Bramley, Leeds. Sept. 7, 1933, No. 24815. [Class 7 (iii)] In a carburetter in which fuel for the nozzles is drawn from an open float the varying height of which controls the admission of fuel to the float chamber, the fuel passes into the float, through filtering holes therein, from the surface layer of the liquid medium in the float chamber. The float may be supported by a liquid, such as water, other than the fuel and the fuel bubble up through the water to form the surface layer. Water, maintained in a float chamber 1, Fig. 2, at constant level by an overflow device 5, 11 in a reception chamber 4 communicating at its base with the float chamber 1, supports an open float 3 into which fuel can flow through orifices 28 to depress it and close a valve by which fuel enters the float chamber. Into the conical base of the float, dips one arm 26 of a pick-up unit providing passages 32, 31 to an inverted main jet 35 screened by an adjustable sleeve 52 which projects into a mixing chamber 30. A byepass 44, Fig. 3, leads out of the passage 31 directly above the main jet 35, to an inverted jet 43 communicating on the engine side of the throttle 57 with the chamber 30. A vaporizer 40 may be associated with the pilot jet 43. A passage 33<a> conducts steam or other vapour from the top of the float chamber to the mixing chamber and is open to the atmosphere intermediate these chambers. Steam from the top of the radiator may also be introduced through a pipe 71. Additional air may enter the induction pipe through an annular passage 67 surrounding a tapering tubular extension 59 of the mixing chamber 30, the amount being adjusted by a valve 61. The float chamber 1 is closed by a gasket 54, metal disc 55 and cover 24 and the latter may be integral with the pick-up unit. In the event of a back-fire, any flame in the float chamber is smothered, the only communication with the atmosphere being through the passage 33<a> but in addition a plug at the base of the reception chamber 4 may be held closed, against spring pressure, by a connection adapted to be fused by the backfire, the arrangement permitting the water in the float chamber to run off and lower the float to close the fuel inlet port.
