Title: Mixed blowing agents for producing cellular polymeric materials
Inventor: CRAM DONALD JOHN
IPC: D06N7/00
Filed: 1961-10-21
Abstract: A composition contains azodicarbonamide as a primary blowing agent and one or more secondary blowing agents which are organic compounds and which decompose at a lower temperature than azodicarbonamide to evolve gaseous products containing elemental nitrogen. The secondary blowing agent may be: benzenesulphonylhydrazide, azoisobutyricamide oxime, dinitrosopentamethylene - tetramine, azo isobutyric dinitrile, p,p1 - oxy - bis - (benzenesulphonylhydrazide), azo - dicyclohexylnitrile and mixtures thereof.  The composition may also contain a resin, e.g. natural rubber, synthetic rubber, polymers of vinyl chloride, styrene, butadiene, chloroprene, propylene, acrylonitrile, acrylates, methacrylates, and polyamides.  A cellular resin may be prepared by filling a mould with the mixture and heating under pressure.  Alternatively, the mixture may be spread on a metal plate, release paper, sheet of plastic or a fabric backing and the heating accomplished statically on on a moving belt through an oven. In Example (1) a mixture of P.V.C., benzenesulphonylhydrazide, azodicarbonamide, white lead paste in dibutyl phthalate, butyl nonyl phthalate, whiting and a chlorinated paraffin was prepared in a mill and spread on a fabric and passed through an infra-red oven at 160-170 DEG  C.  In other examples the resins were (5) a mixture of natural rubber and butadiene-styrene copolymer; (6) a mixture of two styrene-butadiene copolymers.

Abstract: 1282041 Initiating a work cycle in a moving tender LEESONA CORP 28 July 1969 [29 July 1968] 37842/69 Heading DID A system for starting a work cycle in a patrolling tender 26 moving past a stand processing or handling machine e.g. the spindle of a ring frame comprises first photo means 80, 76 for providing a signal when the station is operational, second photo means 82, 86 or 90, 92 for providing a signal when servicing is required and third means responsive to the combination of signals to start a work cycle in the tender. If a roving breaker 64 is in the upright position of Fig. 2 then a ray from source 80 is reflected to cell 76 indicating that the station is operational. If yarn Y is absent a ray from source 86 is not reflected to cell 82, indicating the yarn absence. The combination of these two states initiates a work cycle in the tender. Alternatively if the yarn Y is present but the cells 88 indicate that the bobbin 18 is full, then the appropriate cycle is iniated.

Abstract: 1,218,315. Seed planter. C. J. EMSLIE. 29 July, 1969, No. 37929/69. Heading A1B. A portable seed planter comprises two chambers formed by dividing the outer cylindrical casing H by a partition G, one chamber for seeds, the other for a substance such as a fertilizer, the casing being tapered at one end for insertion into the ground and having orifices in the two chambers such that seeds and fertilizer may be dispensed in adjustable quantities. The seed chambers, closed by a hinged member Q biased to its closed position by a spring R and its volume adjustable by means of the screw T engaged at one end of the operating rod F, is opened by urging the operating rod downwards. Semicircular plates K and M attached to the rod F define a measuring chamber for the fertilizer as in the non-operative position plate N abuts a semi-annular member L attached to the casing to close the chamber and when the rod F is depressed the plate K abuts the member L enabling fertilizer to escape through the orifice P. The amount of fertilizer released can be adjusted by a screw M which alters the volume between plates K and N.

Abstract: 1356662 Heat treating yarns E I DU PONT DE NEMOURS & CO 17 Aug 1971 [17 Aug 1970] 38597/71 Heading D1F A thermoplastic yarn is heat treated by feeding it along a path intersecting a surface oriented to form an angle between the path and the surface normal equal to or less than 15, and preferably equal to or less than 5, and withdrawing the yarn from the proximity of the surface at a rate sufficient to prevent both yarn accumulation and the formation of yarn loops and crimps. Drawn yarn 13, Fig. 1, of bi-component filaments, is heat treated to effect differential shrinkage by feeding it in a stream of heated gas through and from chamber 18 in path 20 perpendicular to the outer surface of cylinder 110, the yarn being withdrawn from the surface along path 30. Part of the gas stream may be deflected from path 20 by the coanda effect of member 19. It is stated that path 20 may terminate in the air layer at the surface. The yarn may be allowed to follow the cylinder surface, Fig. 6, before withdrawal. The surface may alternatively be flat or concave, and may be of metal, glass, paper, wood or plastic. Surfaces of a liquid, e.g. water or mercury, may be used. The surface may be 3 to 16 inches from the chamber exit. The yarn may be overfed into the gas stream, e.g. fed at a velocity exceeding 1000 yards per minute. A plurality of yarns may be fed in parallel to the surface.

Title: Improvements in and relating to glass rolling apparatus particularly applicable to the production of continuous glass strip
IPC: C03B13/04
Filed: 1929-12-28
Abstract: 347,586. Glass manufacture. PILKINGTON BROS., Ltd.,631, Tower Building, Water Street, Liverpool, LE MARE, E. B., Holly Mount, Laurel Road, St. Helens, and WALDRON, F. B., Norwood, Eccleston Park, Prescot, both in Lancashire. Dec. 28, 1929, No. 39674. [Class 56.] Rolling.-Relates to apparatus for forming sheet glass continuously in which a stream of molten glass flows from a spout into the pass between two rollers and is formed by them into a continuous strip. The invention consists in providing means for adjusting the position of one of the rollers by swinging it about the axis of the other, and means for adjusting the position of the pair of rollers relatively to the spout from which the glass flows. The shaft 2 of the lower roller 1 is journalled in a frame 5, and the shaft 4 of the upper roller is journalled in end frames 8 which can turn about the shaft 2. Worm wheel sectors 9 are secured to the frames 8 and are engaged by worms 10 which are geared to a common shaft 15. Thus, by turning the shaft 15, the frames 8 can be swung about the shaft 2 and the inclination of the rollers can be adjusted. The frame 5 is mounted on trunnions 16 secured to a second frame 17, and extensions 7 of the frames 5 are formed with worm sectors 31. Worms 32 engage the sectors 31 and are also geared to a shaft 37, so that by turning this shaft, the rollers can be moved towards or away from the feed spout. The frame 17 slides vertically on guides 18 on a base frame 19, and it can be moved up or down by screws 38 which enter nuts attached to worm wheels 40. A shaft 42 rotates the worm wheels and enables the position of the rollers to be adjusted vertically. The rollers are geared with a worm wheel 26 which is mounted on the trunnion 16 and is rotated by a worm 27 on a driving-shaft 28. The drive of the rollers is thus unaffected by the angular position of the frame 5. A bed 44 fixed to the frame 5 receives the strip of glass issuing from the rollers, and this bed remains in correct position in all positions of the rollers. In a modified construction, the frame 5 carrying the rollers is arranged to slide on the frame 17 to and from the furnace spout. The whole apparatus may be mounted on wheels so that it may be moved away from the spout.
