Title: Fiber blends and yarns spun therefrom
Inventor: HEBELER HAROLD HENRY
IPC: D02G3/24
Filed: 1965-04-15
Abstract: Yarn is spun by the cotton system from a blend of 50-82% of cotton fibre and a "nylon" (i.e. polycarbomides such as polyhexamethylene adipamide or polycaproamide) staple mixture composed of 50-90% uncrimped fibre (having a load-bearing capacity of at least 2.1 g.p.d. at 7% elongation and a boil-off shrinkage of not more than 6%-measured after nine days slack ageing) and 50-10% crimped "carrier" fibres having a crimp index of at least 8%.  The two forms of nylon fibre may be identical e.g. to present the same dyeing effects, or different as regards chemical composition, denier, staple length, and/or filament cross-section.  The carrier fibres may be prepared, during or subsequent to hot-drawing, by stuffer-box, gear, edge, twist or false-twist, or (turbulent) fluid jet crimping combined with heat-setting.  The crimped and uncrimped fibre mix may be prepared by stapling combined tows of continuous filaments thereof, or by blending separately prepared and stapled fibres, and the blended slivers are picked and carded (without the occurrence of excessive mechanical loading usually associated with carding crimped nylon fibre).  The carded sliver is blended with cotton sliver on a draw frame prior to normal spinning.  Conventional additives and finishes e.g. delustrants, dye modifiers, antistatic agents, antioxidants, heat stabilizers, may be incorporated in the fibres. The final yarn is stated to be stronger than a 100% cotton yarn of equivalent count.  The tensile strength of a carded web of the mixed fibre is assessed in terms of card sliver cohesion.  The sliver is passed through two sets of two rollers each and between which a speed differential exists so that a small draft occurs.  The downstream rollers are flexibly mounted and movement thereof, in response to sliver cohesion variation, sends an electrical signal to an appropriately calibrated recorder through a transducer circuit.

Title: Winding
IPC: B65H54/28
Filed: 1975-04-21
Abstract: 1512531 Traversing; tensioning; doffing rubber strip in a winding machine F G CARDINAL and R V CARDINAL 21 April 1975 16448/75 Headings DID D1F and D1J [Also in Divisions B7 and F2] A machine for winding rubber strip onto a spool 20, Fig. 7, comprises:-a horizontal spindle 22b for supporting a spool 20; spoolengaging means 40 rotating with the spindle 22b; drive means 85 for rotating the spindle 22b and thus the spool 20, the drive means 85 including torque-limiting means 86 to control the tension in the strip being wound on the spool 20; traversing means 94 driven by the drive means 85 for traversing the rubber strip onto the spool 20; and spool ejector means 116, 118 for pushing a spool 20 off the spindle 22b. In Fig. 7 torque-limiting means 86 is stated to be an eddy current drive arrangement adjusted to disengage the output shaft 87 at a predetermined torque. Any equivalent electrical, mechanical or other torque limiting control may be provided between the motor 85 and the spindle 22b. The output shaft 87 of the torque limiting means 86 is transmitted to a gear box 89 having a single input 90 and two outputs, one at 91 driving the spindle 22b and one at 92 driving the traverse mechanism 94. Traverse means. The traverse means 94 is motivated by an endless chain 106 running around spaced sprockets 107, 108. The chain 106 carries drive pins 104 that extend into an elongated slot 102 in a slide block 100. Thus, whilst the pins 104 are on the upper run of the endless chain the pins 104 are at the upper end of the slot 102; but as the pins then pass around a sprocket 107. or 108, the pins 104 move to the lower end of the slot 102. The slide block 100 is thus caused to reciprocate and is coupled to the traverse means 94 by a rod 98. Doffing means. When the spool 20 is fully wound a fluid actuated cylinder 116 forces a ram 118 to the right in Fig. 7. The ram 118 then abuts against both the spool 20 and a wheeled platform 120 positioned under the spool 20. Both the spool 20 and the platform 120 are then forced to the right until the spool 20 leaves its spindle 22b and drops onto the platform 120. Thereafter, the spool can be rolled off the platform 120 and down ramps to the floor of a building for storage or for removal by a cart 26, Fig. 3. Cart. The fully wound and doffed spools 20 can be picked up by a cart 26, Fig. 3, for transport to a tyre re-mould extruder. The cart 26 has two upright support posts 54 and on each post 54 is a clevis 56 which, when in the position shown in full lines, can be brought into engagement with the spool mandrel 39. When a pair of lever arms 66 are swung from the full line setting to the broken line setting the clevises 56 are rocked from their full line setting to their broken line setting and the spool 20 is then raised-up off the floor. The arms 66 may carry a handle 72 for pushing the cart. Alternatively the handle 72 may be separate from the arms 66 so as to be permanently in a pushing setting.

Patent GB-396206-A (GB)
Title: Improvements in the manufacture of yeast and other microorganisms
IPC: C12P33/00
Filed: 1932-06-10
Abstract: Yeast and similar organisms of high ergosterol content for use as food for human beings and animals and for medicinal purposes are produced by cultivation under such conditions that during a whole or part of the treatment they are subjected in the presence of an oxidizing agent or oxygen carrier in an aerated medium to deficiency in nitrogenous nutrient while other nutrient substances are supplied in normal amount.  The cultivation is preferably carried out at temperatures somewhat higher than the usual temperatures employed for yeast propagation, for example, from 86 to 100 DEG  F.  The nitrogen deficiency may be brought about by adding the whole of the reduced amount of nitrogenous salts either in the early stages of the fermentation or during the whole period of the growth of the yeast, or by further treating under propagating conditions yeast that has been prepared under normal conditions, no further addition of assimilable nitrogen being made.  Suitable oxidizing agents or oxygen carriers are salts of "per" acids such as sodium persulphate, and methylene blue.  The process is applicable to organisms capable of producing ergosterol, such as S. Cerevisiae and S. Carlsbergensis. The Provisional Specification refers also to Torula utilis.  The ergosterol content of the yeast produced may be still further increased by exposure to air.  Examples are given.

Title: Improved arrangement for disengaging the picking catches of a loom
IPC: D03D49/58
Filed: 1937-06-17
Abstract: 497,352. Picking-mechanism for dropbox looms. MASCHINENFABRIK C. ZANGS AKT.-GES., and ZANGS, A. June 17, 1937, No. 16880. [Class 142 (in)] If a shuttle box is incorrectly positioned at the box change, safety means in the connection between the shuttle boxes and the driving means therefor is actuated and the picking catches on both sides are disengaged. Thus'when the shuttle box is supported by two telescopic parts which are normally negatively connected together by a roller 4 on a spring controlled bell-crank lever 6 engaging a groove in one of the parts, rocking of this lever raises a rod 10 connected to a lever 9 pivoted at 7 on the change lever 8. A roller 11 on this lever is thus moved from its normal position wherein, as the change lever rises and falls, it moves idly along a curved segment 14 on a slide 13 to a position wherein it moves the segment 14 to the left. A pusher 15 on the segment thereupon rocks one of two levers 18 fixed on a shaft 17 mounted parallel to and in the vicinity of the axis of rotation of the lay sword. Locking-levers 20, 21 on the shaft 17 thereupon move into position to lock both of the bell-crank levers 22, 23 which control the picking, so that picking from both sides of the loom is prevented. Each lever 22, 23 transmits by lever-mechanism the movement of the swell feeler on one side of the loom to the picking catch on the other side. The slide 13 is guided in a mounting 12 on the loom frame and the segment is concentric with the pivot of the change lever 8.
