A connector for a series of flat co-planar conductors supported in a dielectric, namely a " tape " cable, comprises similarly spaced contact members, each having a number of teeth which may be so moved relative to the cable as to penetrate its insulation and make a scraping connection with a conductor. In all the following embodiments, the contact teeth act in such a way as to cause varying penetration of the cable, so preventing severance of the conductors in front of the connections. Two-part couplings.-In one embodiment, Fig. 2, a pair of wedge-shaped insulating blocks 11, 13, carry contacts 15, 17 staggered transversely and longitudinally for engagement with spaced conductors 37 of tape cable 35. The latter is passed through a slit 33 in a housing 27 having a tapered cavity 29 to receive blocks 11, 13, and between said blocks which are cammed together and against the cable by the cavity 29. Each of contacts 15 and 17 has teeth 41 and 43 of varying length, and terminate in spring tabs 45 and 47 respectively. These tabs project through a sealing gasket 57 and a pressure plate 59 to engage with a similar, mating connector. In another embodiment, Fig. 9, two tape cables may be connectad together by identical connector assemblies 211, 213 and an intermediate block 215. A block 217 carries contacts 219 with teeth 223 of varying length projecting from the surface of a V-shaped recess 221 of the block for engagement with the conductors of a cable 35 passed through a cable clamp 231 and around a pressure bar 225, which is then tightened against the block 217. The front portions of contacts 219 are tabs 243 which mate with corresponding tabs inside passages 241 of the block 215. Variants of the contact-pressure bar arrangement of this connector are described (Figs. 14, 15, 16, 17, not shown). " Terminals.-fig. 5 shows an assembly for making connections between the conductors of a tape cable 35 and flexible conductors 119. Arcuate tapered contacts 111 are free to move transversely through vertical arcuate slots 113 in a block 115. The cable 35 is inserted through a transverse slot intersecting slots 113 until it engages teeth 117 on contacts 111, when it is pulled back, drawing with it contacts 111 which are then cammed into the cable by the slot surfaces. In the embodiments of Fig. 20, a contact block 711 is hinged at 713 to a base 715, and has contacts 717 which are eccentrically shaped around the pivot 713 and have teeth to engage a cable 35 when block 711 is swung into a closed position.

Abstract: 1,274,364. Fancy yarn; twisted strips. GLANZSTOFF A.G. 4 May, 1970 [26 June, 1969], No. 21341/70. Headings D1F and D1W. A process for producing a fancy yarn having a homogeneous distribution of the fibre length between staple length and continuous portions comprises producing a fleece by depositing continuous filaments in a statistically random fashion on an endless belt moving at constant speed, at least temporarily strengthening the fleece e.g. by the addition of a binder, and cutting the fleece into continuous strips, the strips being twisted to produce a fancy yarn. In a preferred embodiment, threads 1 are drawn from a creel and opened into the individual filaments 3 by air jets 2 prior to being deposited on an endless belt 4. A watersoluble binder is sprayed on to the fleece at 6 and the strengthened fleece 5' is cut into strips 8 by knives 7. The strips 8 may be pulled between pairs of rolls 9 and 10 prior to being twisted on a ring twisting machine. The threads 1 may be of different colours and at least two strips of different colours may be twisted together to form the yarn. In a further embodiment, the strengthened fleece is wound on a support and the resultant package is cut into discs which are twisted to form the yarn. When the fleece is temporarily strengthened by means of a water-soluble binder, the binder may be washed out of the yarn.

Filed: 1933-11-18
Abstract: 431,971. Operating clutches. BENDIX AVIATION CORPORATION, 105, West Adams Street, Chicago, U.S.A. Nov. 18, 1933, No. 21667 /34. Convention date, Nov. 19, 1932. Divided out of 429,264. [Class 80 (ii)] The bleed through a conduit 254 from the non-suction end of an accelerator-controlled engine-suction servomotor operating the clutch of a motor-vehicle is determined by the clearance between a pair of spring-loaded plungers 268, 268<1> which are controlled by governors 256, 256<1> driven in accordance with the speeds of the driving and driven members of the clutch, respectively. Plugs 274 adjustably mounted in one of the plungers determine the minimum clearance between the plungers, the outward movement of which is limited by stops 278, 278'. At idling speed of the engine, the plunger 268 is in its innermost position. On depressing the accelerator, the first part of the engaging stroke is relatively rapid, due to the provision of a slot in the servo piston rod, the speed of the remaining part of the stroke being governed by the clearance between the plungers. In starting the vehicle from rest, as the engine is accelerated, the plunger 268 moves to the left, followed by the plunger 268<1>, thus maintaining the minimum clearance until the governor 2561 begins to function. The rate of engagement then progressively increases as the drive is taken up. Specification 429,264 is referred to.
