Abstract: 424,444. Feeding sheets. THOMPSON, M. P., 14, West Park Drive, Roundhay, Leeds. Nov. 29, 1933, No. 33485. [Class 100 (i)] In a machine for labelling bottles &c. in which the labels are fed from a pile 1 by means of an adhesive or suction picker 16, the separation of the labels is facilitated and double feed prevented by forming a hump in the endmost label by applying pressure laterally of the pile by means of two yielding strips or fingers 3 which are mounted on carriers 4 and are pressed into engagement with opposite edge of the pile by means of springs 22 arranged on bolts 5 on which the carriers 4 are mounted. The bolts 5 are mounted in brackets 6 connected to a yoke 8 which is reciprocated vertically by a rod 12 operated from a cam on a shaft 17, and the pneumatic picker 16 is also actuated by the rod 12. As the rod 12 descends, the fingers 3 move inwards to form a hump in the middle of the sheet, and when the cam permits, springs 21 return the carriers 4 to their initial position. The springs 22 maintain the fingers 3 in contact with the top label until the carriers 4 are moved about their pivots by means of fixed stops. The pile table is maintained in its raised position by means of weights 29, and a cushioning spring 30 is provided for the label holder.

Abstract: 780,755. Crimping and stapling fibres. IMPERIAL CHEMICAL INDUSTRIES, Ltd. Nov. 2, 1955 [Nov. 19, 1954; Jan. 24, 1955], Nos. 33539/54 and 2024/55. Drawings to Specification. Class 120(3) In a process for continuously melt spinning, drawing and crimping filaments from synthetic linear polymers, e.g. polyethylene terephthalate, filaments coming from the spinneret are passed at a winding speed of the order of 100 times that at which they would leave the spinneret without being wound e.g. at 10,000 feet per minute, through two sets of individual teeth, which may be of rectangular block form with rounded or tapered tips, attached to and projecting from a core each mounted on a driven wheel so that the teeth intermesh e.g. in the manner of spur, contrate or bevel gears, without touching, to draw and crimp the filaments. Certain teeth spaced at equal intervals on the periphery of one or both wheels may project beyond the other teeth in order to sever the filaments into staple lengths. In the apparatus described, the amount of intermeshing (which may be adjustable), and the distance between successive teeth is greater than the thickness of each tooth; individual teeth in the form of steel blades are locked within grooves in the core.

Abstract: 1,249,390. Vinyl ester copolymers; electrocoating compositions. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 6 April, 1970 [3 July, 1969], No. 33543/69. Headings C3P and C3R. [Also in Division C7] The invention comprises novel interpolymers obtained by copolymerizing in one or more stages, a monomer mixture consisting of (a) 20- 80% by wt. of a vinyl ester of one or more saturated aliphatic monocarboxylic acids of 5-20 carbon atoms in which acid, the carboxyl group is attached directly to a tertiary or quaternary carbon atom, (b) 2-20% by wt. of an alpha, beta-ethylenically unsaturated carboxylic acid of 3-5 carbon atoms, (c) 5-40% by wt. of a monovinyl aromatic compound of 8-9 carbon atoms, (d) 5-35% by wt. of a 2- hydroxyalkyl ester or an amide of an alpha, beta-ethylenically unsaturated carboxylic acid and (e) 0-25% by wt. of a C 1  to C 4  alkyl ester of acrylic or methacrylic acid. Monomers (a) specified are vinyl esters of commercially available "branched" aliphatic monocarboxylic acids of 9-11, preferably 10, carbon atoms from the cracking of paraffin hydrocarbons. Monomers (b) specified are acrylic, methacrylic, maleic, fumaric, aconitic and itaconic acids. Monomers (c) specified are styrene and vinyl toluene; monomers (d), 2-hydroxyethyl acrylate, 2- hydroxyethyl methacrylate (preferred), 2-hydroxypropyl acrylate and methacrylate, mono- and di-2-hydroxyethyl esters of maleic or fumaric acids, acrylamide, and N-hydroxymethyl acrylamide, and monomers (e), methyl methacrylate. Polymerization may be by any of the standard methods, but solution is preferred. A preferred process involves charging a reactor with all of monomer (a) and 5-15% by wt. of the other monomers and polymerizing, whilst adding the rest of the monomers in one or more subsequent stages. In the examples, interpolymers are made by the "staged" process from (1) a mixture of vinyl esters of saturated aliphatic monocarboxylic acids of 9-11 carbon atoms, branched at the alpha carbon ("Veova" -Trade Mark), acrylic acid, styrene, 2-hydroxy ethyl methacrylate and methyl methacrylate using as an initial initiator, di-t-butyl peroxide, and as further initiator with the subsequent addition of monomers (b) to (e), benzoyl peroxide, in a solvent mixture of ethylene glycol monobutyl ether, and benzyl alcohol, and (3) "Veova", methacrylic acid, styrene, and 2- hydroxyethyl methacrylate, polymerized in stages in a mixture of 2-methoxy ethanol and tetrahydrofurane, using benzoyl peroxide as the sole initiator. In these examples, the resultant polymer solutions are compounded with (1), a melamine formaldehyde resin and triethylamine, (for partial neutralization), in aqueous solution to form a binder, to which rutile TiO 2  and further binder solution and water is added, and (3) with melamine formaldehyde resin, dimethyl ethanolamine (for part neutralization), in aqueous solution, to form a binder which is compounded with TiO 2  to form a paint as in (1). They are then subjected to electrodeposition (see Heading C7B).

Title: Bracing device particularly suitable for use at the end of a face conveyor at a coal face where a coal plough is employed
IPC: E21F13/10
Filed: 1964-08-17
Abstract: 1,082,257. Advancing mine face conveyers. H. BEUKENBERG, H. BEUKENBERG and K. BEUKENBERG, [trading as MASCHINENFABRIK GLœCKAUF GœNTHER KLERNER]. Aug. 17, 1964 [Aug. 17, 1963], No. 33553/64. Headings B8A and B8J. A bracing device for the end of a face conveyer, in which telescoping hydraulic props braceable between the floor and roof and preferably tiltable, is characterized in that a signal is given when the props are so far extended that, owing to insufficient roof contact, efficient bracing is impossible. As illustrated in Figs. 1, 2 (not shown) the bracing device is associated with a free conveyer (1) and comprises a counter support (2) with tiltable telescopic props (3), (8) each with hinged caps (9). The driving station of the conveyer (1) is connected with a slide guide (4) enclosing the counter support (2). The slide guide (4) with the counter support (2) and the conveyer (1) are alternately movable in the bace advancing direction while reciprocally guiding one another, by a double-acting hydraulically operated cylinder (5). A doubleacting hydraulic tensioning cylinder (6) is provided. Fig. 3 shows an inner prop 11 with a piston 12 having a collar 22 arranged to engage in a control chamber 23. When the inner prop 11 is extended driving medium displaced above the piston 12 escapes through a conduit 29. Prior to reaching the upper end position the control chamber 23 is closed by the collar 22 and driving medium trapped in the chamber 23 is forced through a conduit 24 to act upon a spring- loaded control piston 25 to open a shut-off member 26 and connect a compressed-air supply to a signal whistle 28. Instead of a compressed-air supply a cartridge of compressed gas may be pierced by a pointed extension on the piston (25) (Fig. 4, not shown). Figs. 5, 6 show a further embodiment in two different operating positions. In Fig. 5 driving medium from a pump is fed through a conduit 31 and a valve 38 to extend an inner prop 11 with a piston 12, driving medium above the piston 12 returning without pressure to the pumping unit through conduits 35, 36. When the inner prop 11 is fully extended (Fig. 6) the piston 12 lifts a control member 14 to open a back-pressure valve 33 to allow the driving medium to circulate freely through conduit 32 and control chamber 23 to conduits 35, 36 and thus back to the pumping unit. At the same time back-pressure valve 38 closes to prevent driving medium returning from below the piston 12. As a result a bracing pressure cannot be built up in the chamber below the piston 12 and a pressure gauge 39 indicates a considerable drop in pressure as a warning signal. The inner prop 11 may be retracted (Fig. 7, not shown) by applying driving medium to conduit 36 which closes a valve 34 and acts on a differential piston 37 to open the back-pressure valve 38. As a result the piston 12 is forced down, driving medium below the piston 12 returning to the pumping unit through the valve 38 and the conduit 31.

Abstract: 1439964 Crystallizing polycarbonates UNIBRA 13 July 1973 [27 July 1972 26 Feb 1973] 33582/73 Heading C3R A process for crystallizing a polycarbonate comprises mixing a finely divided nucleating agent selected from inorganic salts of organic acids with the polycarbonate and crystallizing the mixture at a temperature higher than the vitreous transition temperature, i.e. the minimum temperature at which the polymer will crystallize from the polymer-containing mixture. The nucleating agent is preferably used in an amount of from 0À01 to 20% by weight, based on the total composition, and preferably has an average grain size lower than 5 microns. The semi-crystalline polycarbonate obtained by the above process may be used as a nucleating agent for the crystallization of a second batch of polycarbonate. The preferred polycarbonate is that derived from bisphenol A and various nucleating agents are specified, e.g. K, Na, Zi and Zn benzoate and Na benzene sulphinate. In the examples, the semi-crystalline polycarbonate obtained by the above process (i) is used as a nucleating agent together with a trimellitic ester plasticizer for a further batch of polycarbonate, and (ii) is reinforced with glass fibres.
