Filed: 1976-12-17
Abstract: 1521169 Transporting packages between machines; doffing; creels TORAY INDUSTRIES INC 17 Dec 1976 52788/76 Headings DIF and D1J Yarn packages are transported from a first yarn package forming machine 20 having a plurality of winders to a second yarn package forming machine 40 also having a plurality of winders by doffing at stage 24 the packages from the first machine 20, transporting the packages to a transferring stage 30 and transferring the packages to a second transporter which functions as a creel for supplying filament yarns at the second machine 40, and transporting the packages to the second machine 40. The first package transporter is returned to the first machine 20 and the second transporter is returned to the package transferring stage 30. The first and second transporters may pass via storage regions 28, 38, 34, 32. The movement of the transporters may be effected by endless chains and a control unit 26. The paths of the packages are shown in detail in Fig. 2 (not shown). The first machine 20 may wind undrawn synthetic yarn. The second machine 40 may draw and twist the yarn. Doffing from the first machine 20 is effected by pusher (76) sliding a pair of wound packages sideways onto a peg (54) on a transportable package carrier (52). Thirty-six pairs of packages may be simultaneously doffed onto six carriers (52). Precise positioning of the carrier (52) in front of the first machine 20 is effected by switch and magnet (73 and 64) or mechanically. see Figs. 3 and 4 (not shown). First carrier (52), Fig. 5 (not shown) comprises sets of package carrying pegs (54) on a wheeled trolley which is driven by a pin (62) engaging with an endless chain below the floor. The carrier (52) is disengaged with the endless chain at the doffing station or when carriers are linked together. Carrier (52) drive is effected by blocks (80) mounted on the endless chains arranged between and around the two machines 20 and 40. Transfer of the first and second carriers between the endless chains is effected by a paddle mechanism engaging with the pins (62) on the carriers, Fig. 6 (not shown). Package transfer stage Fig. 7 (not shown) comprises an arm (106) movable in predetermined sequences (Figs. 8 and 9 not shown) to lift the packages from the first carrier(s) (52) to a second carrier (120) acting as a creel. The positional relationship of the packages on the carrier(s) (52) and the creel carriers (120) is predetermined, see Fig. 10 (not shown). Second (creel) carrier (120) as illustrated in Fig. 11 (not shown) comprises a package supporting framework on a wheeled trolley movable by endless belts in a manner similar to the carrier (52). Preferably the creel carrier (120) is stopped immediately above a draw twisting machine 40, Fig. 12 (not shown).

Abstract: 1,027,188. Hydraulic couplings. F. A. DEPUYDT Dec. 30, 1964, No. 52913/64. Heading F2C. [Also in Division B7] An hydraulic coupling between input shaft 108 and output shafts 129, 138 connected by chain transmissions to two vehicle wheels, Fig. 2, not shown, comprises a housing 99, 101 connected to shaft 108 and having a vaned disc 113 dividing the housing into chambers 116, 117 connected by ports 121 in disc 113. In chamber 117 two vaned rotors 128, 144 are connected to shafts 129, 138 and face the vaned disc 113 and the vaned housing wall 122; the shaft 129 is supported through a roller bearing 131 on a stub axle fixed between disc 113 and housing hub 106. In chamber 116 a cage 150 rotatable on hub 106 carries radially movable blocks 151 biased by springs 156 toward the hub. The cage comprises two discs 154, 155 and U-shaped members 158; grooves in the blocks 151 engage the members 158 for radial guidance and rods 166 fixed to members 158 have two notches which are engaged by spring-pressed plungers in the blocks, Fig. 10, not shown, to hold the blocks in their inner or outer radial positions. In operation, as shaft 108 and the housing increase speed, hydraulic fluid in chamber 116 causes the cage to rotate and eventually due to centrifugal force the blocks move outwardly to force fluid through ports 121 into chamber 117 to establish a coupling between the housing and disc 113 and the rotors 144, 128. When shaft 108 slows down, the springs 156 eventually overcome the centrifugal force and the action of the plungers on blocks 151 to return them to the shown position and allow the fluid to be drained from chamber 117 to chamber 116. In Fig. 3, not shown, the blocks are guided by and rotate with the housing.

Abstract: 1,196,620. Resistance heating elements. SMITHS INDUSTRIES Ltd. 24 Jan., 1969 [1 Dec., 1967], No. 54806/67. Heading H5H. In a heating assembly of the kind comprising a coiled heating element 17 supported by a plurality of spaced insulating plates 1, 2, 3, 4, 5, which are mounted between a pair of metal plates 6, 7, successive portions of the heating element between adjacent insulating plates are inclined so that each length of the element between end plates 1, 5 is slightly zig-zagged, with the result that the element is held by its spring tension in engagement with the insulating plates 1, 2, 3, 4, 5. The plates 6, 7 are retained sprung together by means of one or more wire springs which comprise straight sections extending between the plates and swan-neck ends which engage the plates 6, 7. The swan-neck ends may pass through slots in the plates or over the edges of the plates and may be retained in holes or recesses in the plates. The spacers have slots in their side edges which support element 17. Adjacent spacers may be different, i.e. their slots may be slightly staggered to produce the zig-zag configuration of the heating element. As shown, the spacers 1, 2, 3, 4, 5 are identical and staggering of the supporting slots of adjacent spacers is achieved by mounting alternate spacers at different levels. As shown spacers 1, 3 and 5 are located at one level by recessed portions 11, 13, 15 of plate 6 and spacers 2, 4 are located at another level by recessed portions 12, 14 of plate 7. Tabs 8, 9 of each insulating spacer pass through slots in plates 6, 7 and are retained therein by deformation of a metal strip between the tab slots and an adjacent slot, a screwdriver being inserted in the adjacent slot and rotated to deform the metal strip.

If no useable register accessible to that M.C.V. is available, the M.C.V. searches in a cyclic store for free useable register, selects such a register, connects that register to the calling line or junction and transfers control of the connection to the M.C.V. which has access to that register. Transfer of connection data may take place via an exchange management processor as shown or any other "inter-control-unit" arrangement.
