As the package decreases in diameter the flexible web 32 presses against the part 30 to cause the part 28 to swing clockwise and so keep the web 32 in contact with the circumferential periphery of the package 16. The particular arrangement shown in Fig. 2a is for a package in which when the yarn is drawn off over-end towards the viewer, the drawn off yarn is rotating in the direction of the arrow on the package 16. If the drawn off yarn will be rotating in the opposite direction then the arms 24 are swung to the broken line setting, the supporting device 28, 30 is arranged to hang downwardly on the left hand side of the package 16, and the web 32 extending from the part 30 is then wrapped anti-clockwise around the package 16 so as to hang downwardly on the left hand side of the package.

Title: Synchronised jaw clutches
IPC: F16D23/06
Filed: 1964-09-07
Abstract: 1,009,317. Positive clutches. EATON MANUFACTURING CO. Sept. 7, 1964 [Oct. 16, 1963], No. 36625/64. Heading F2L. Synchronized engagement of positive clutches 6, 21; 17, 22 in a motor car &c. change-speed gear is obtained by a pair of balk-rings 31, 33, selectively engageable with frusto-conical friction surfaces 32, 34 associated with the two positive clutches and fast with two sets of balking pins 44, 41, respectively. The balking pins 41, 44 pass through oversize holes 26, 27 in a flange 19 of a clutch selector splined for axial movement on a driven shaft 8, and are formed with flared balking surfaces 42, 46 for cooperation with corresponding shaped surfaces 28, 29 at opposite ends of the two sets of holes. The pins 44 are fast with the balk ring 31, but only abut the balk ring 33. The pins 41 are fast with the balk ring 33, and extend into oversize holes 36 in the balk ring 31. Circumferentially arranged springs 48 in holes within the balk ring 31 engage the ends of the pins 41 within the oversize holes 36, and bias the balk rings 31, 33 to turn in opposite directions relatively to each other. Thus, when the clutch selector is in its neutral position, Fig. 4 (b), the flared balking surfaces 42, 46 are held by the bias of the springs 48 in engagement with the correspondingly-shaped surfaces 28, 29 at the ends of the holes 26 in the flange 19. On initiation of a clutch-engaging movement by sliding axially the clutch selector, either the balking surfaces 29, 46 or the balking surfaces 28, 42, as appropriate, transmit axial movement to the balk rings 31, 33, respectively. Engagement of the associated friction surface 32, 34 twists the balk ring 31 or 33, and maintains the balking surfaces 29, 46 or 28, 42 in contact. Further movement of the clutch selector is thus prevented. On synchronism, the balking surfaces 29, 46 or 28, 42 can slide over each other to the positions shown in Fig. 4(a), Fig. 4(c). Engagement of the positive clutch 6, 21 or 17, 22 is then effected.

The reaction is performed in a liquid reaction medium in the presence of a strong acid, and the products have the formul t e: Me a -BMo c O z , where Me is Bi or Te, B is Mn, Co, or Ni, x is a number from 0-1 to 18 and z is a number from 29 to 65; Me x AMo 12 O y , where Me is Bi or Te, A is Ti, Zr, or Sn, x is a number from O'l to 18, and y is a number from 38 to 74; and Mea-tCgMo ia O w ], where Me and are as above, C is Cr, Al or Fe, and w is number from 39 to 75. The above compounds are prepared from the corresponding acids H 4 (AMo 12 O 40 ); H 6 (BMo 9 O 32 ); and H 6 (C 2 Mo 12 O 42 ). The above materials are used as catalysts in the preparation of organic nitriles, preferably unsaturated nitriles, from defines, e.g. propylene by the action of ammonia and oxygen. The catalytic material may be activated before use by heat treatment at a temperature between 400‹ and 600‹ C. for a period of time from 5 to 30 hours. Prior to the heat treatment there may be added to the catalyst an organic substance, e.g. oil, glycerol, polyvinyl acetate, and polyvinyl alcohol, which substance decomposes on heating to increase the porosity of the catalyst. A support material, e.g. silica aerogel, may be mixed with the catalyst. In the nitrile producing reaction which is carried out at a temperature of 300‹ to 600‹ C., the contact time of the gaseous reactants on the catalyst is between 0-05 and 20 sees., and the proportions of reaetants are such that the mixture contains between 0À5 and 2-5 moles of oxygen and between 0-3 and 2 moles of ammonia per mole of olefin. The reacting gases may be diluted with an inert gas, e.g. a paraffinic hydrocarbon, N 2 , CO 2 , or steam.
