Title: Yarn Hanks and Method of Manufacturing same
IPC: B65H54/62
Filed: 1966-11-30
Abstract: 1,167,360. Yarn hanks. ERBA MASCHINENBAU A.G. 30 Nov., 1966 [1 Dec., 1965; 7 March, 1966; 27 June, 1966], No. 53617/66. Heading B8M. [Also in Division D1] A hank is built up of continuously staggered cross-wound layers, the first layers being formed into an initial cone by continuous displacement, the later layers extending beyond the initial cone with the same degree of taper, and the whole being such that the thread can be axially drawn off from the hanks without the latter having to rotate, and is characterized in that the layers are secured by lacing comprising a plurality of laces 5 arranged on the periphery of the hank so that the hank is sub-divided along its length into a plurality of sections. Divider elements 3 are used which are themselves attached to a longitudinally stable element 4 over the full length of the hank. The divider elements may be formed in situ by threads, a row of hooked needles being forced through the hank from the outside into the internal cavity of the hank where a tie-off thread is passed through the needle hooks, the thread being pulled through the hank windings in the form of loops when the needles are withdrawn. The loops so formed are then attached to longitudinally stable elements by welding, sticking or clamping. The start and end of each section may be indicated by colour coded stabilizing elements.

The upper surface 17 may comprise a layer of foam which has its upper surface heat-treated to provide said impedance and which is releasably secured to the main body of the mattress. The main body of the mattress may also have its upper surface heattreated. A continuous plastics material film e.g of polyurethane, silicone or vinyl co-polymer resin may be secured to the upper surface of the layer 17 or directly to the upper surface of the main body 12, the film being provided with an outlet for discharge gas and not being capable of retaining or transmitting solids but allowing water vapour to pass therethrough. The body 12 may comprise a number of individual foam blocks with individual valve controlled air supplies. Blocks of foam 22 having a greater density than that of the body 11  may be located below and along the sides of the body. Foam-backed end-plates may be bonded to the ends of the foam body.

A device for use in the erection of posts or masts and which is adapted to be mounted on a tractor loader arm consists of a cradle comprising upper and lower sections 40, 41 interconnected by brackets 42, 43. The upper section comprises a bar 46 which is open at its ends to receive cradle elements 47, 48 consisting of rollers 53, 54 on spindles projecting through slots in the bar 46 and secured to blocks 49 mounted in the bar. Similarly, the lower section 41 comprises rollers 65, 66. In operation, to raise a post from the horizontal position and to erect it in a hole h, Fig. 10, the lower cradle section 41 is engaged with the post, the loader arm is raised and the tractor is driven towards the hole, which is provided with a buffer b, whereby the post is raised until it is engaged by the rollers of both cradle sections, Fig. 10, and subsequently by the upper section rollers only, Fig. 11 (not shown). As the post approaches the upright position, it is secured to the lower cradle section by a chain halter whereby the post may be held in the desired position whilst the hole around the post is filled in. The device may be constructed as an attachment for fork arms of a loader arm device such as is disclosed in parent Specification 1,178,332, Fig. 1, or may be mounted directly on the loader arm.

Abstract: 1388878 Antibiotics A28695A and A28695B ELI LILLY & CO 4 Dec 1972 [23 Dec 1971 27 Sept 1972] 55939/72 Heading C2A The novel antibiotics A28695A and A28695B which are non-nitrogenous, acidic, white crystalline solids melting at 97 to 99 C. and 122 to 124 C. respectively and having the respective elemental compositions: C=63À31%, H=8À83%, O=28À03% and C=60À49%, H= 9À15%, O=31À32%; and molecular weights: 834 and 846, are produced by aerobically cultivating Streptomyces albus (NRRL 3883) in aqueous nutrient medium containing assimilable sources of carbon, nitrogen and inorganic salts until a substantial amount of the said antibiotics have accumulated in the culture medium. The antibiotics are extracted from the mycelium and the culture fitrate with an appropriate organic solvent, e.g. methanol or ethyl acetate for the mycelium and ethyl acetate for the filtrate, the extracts then being combined and concentrated to an oily residue which is taken up in chloroform and the solution is purified by treatment with carbon. Evaporation of the chloroform solution gives a crude mixture of the two antibiotics. These are separated and isolated as their mixed sodium/potassium salts by cromatography on a silica gel column, eluting with a benzene: ethyl acetate (4 :1) solvent, when the sodium/potassium salt of A28695A is eluted first followed by the corresponding salt of A28695B. The salts are purified by recrystallization from ether. The free acids may be prepared by treating these salts with HCl. The mixed sodium/potassium salts of A28695A and A28695B are characterized by the respective following properties: Melting points: 161 to 165 C. and 170 to 172 C.; specific rotation, [α]<SP>25</SP> D = + 14À07 and +10À1 (C=1 in methanol); and infra-red absorption spectra as shown in Fig. 1, and in Fig. 2. Both salts are white crystalline materials, insoluble in water, slightly soluble in methanol and soluble in most other organic solvents. The antibiotics A28695A and A28695B and their salts have antibacterial, antiviral, antifungal, insecticidal and anthelmintic activity. They may be used in compositions for treating plants infected with fungi or viruses, in animal feed compositions or pre-mixes therefor to increase feed efficiency, and in compositions for administration to poultry to treat or prevent avian coccidiosis.

Abstract: 1,255,141. Internal shoe drum brakes. GIRLING Ltd. 9 Dec., 1968 [9 Dec., 1967], No. 56084/67. Heading F2E. An internal shoe drum brake actuator comprises a housing 10 having an internal chamber 16 from which two aligned bores 12, 14 extend outwardly containing plungers 18, 20 with slotted inner ends in which rollers 22 of greater diameter than the plungers are mounted and a displaceable wedge 26 between the inner ends of the plungers which in operation bears on the rollers. The plungers act on brake shoes having return springs and outward movement of the plungers applies the brakes. Movement of the plungers is limited by pins 32 or a part of the housing 10 slightly enlarged on the face abutting the rollers. The wedge is mounted on a push rod 28 or a pull rod actuated by an hydraulic piston, a cam or a lever system. To allow pins 24 to be inserted through the rollers and the ends of the plungers the top of the housing is open and the rollers and plungers are rotated through 90 degrees. The rollers and plungers are then rotated back, pushed outwards and secured by a circlip 21 and cap 19. To ensure that the rollers and wedge remain coplanar they are enclosed in a T-shaped cage 34 which is biased against them by a cover-plate 38 to prevent rattle. The side walls of the housing may contain holes to allow the pins to be inserted without rotation. A side wall may be outwardly inclined so that the pins can be inserted with only partial rotation of the rollers and plungers. A bearing may be located between each pin and its roller.

Blanks 4 are stacked and aligned against a stop 1 by friction belts 18 and friction rollers 13. The stack is supported upon rails 9 carried on pins 10 and biased upwardly by springs 12. When the stack reaches a predetermined size the combined weight thereof and the pressure due to rollers 13 and belts 18 forces rails 9 to descend between driven separator belts 5 until the lowermost blank is carried away by these belts and fed to belts 22, 23. The pressure of rollers 13 may be adjusted by springs 16 to ensure that the stack is maintained at a predetermined size during simultaneous stocking and separation. The device is used in connection with the production of tubular blanks having freshly gummed seams, the dwell of each blank in the stack allowing time for the newly gummed seam to set before the blank is conveyed onwards for further processing. The pressure rollers 13 and the belts 18 are arranged to press on both sides of the gummed seams.
