Patent GB-853325-A (GB)
Title: Improvements relating to treatment of threads and filaments of synthetic materials
IPC: D06M15/347
Filed: 1958-05-07
Abstract: The surfaces of threads and filaments of synthetic materials are roughened by producing in situ on the thread or filament a coating of a synthetic thermoplastic resin by reacting polyvinyl alcohol and 3-hydroxy -nbutyraldehyde in the presence of an acid polymerisation catalyst.  A swelling agent or solvent which has a swelling effect on the material of the thread or filament itself and also on the synthetic resin coating may also be present. Aqueous solutions of polyvinyl alcohol and 3- hydroxy -nbutyraldehyde may be used and the coating produced by heating the filaments or threads which have been treated with the solution to a temperature above 100 DEG C. Suitable acid polymerisation catalysts are phosphoric and glycollic acids.  If the filaments or threads are subsequently to be bonded together with polyvinyl chloride or natural rubber, a suspension of an acrylonitrile-butadiene polymerisation product in an amount corresponding to the other dissolved substances and an emulsion of natural rubber, preferably in the same amount as the butadiene polymerisate, may also be added to the solution.  The filaments and threads may be made up into knitted fabrics having less tendency to ladder or into nets having knots with less tendency to open, or the fabrics or nets may be given a coating of the synthetic resin after their manufacture, in which case they are preferably held under tension during the condensation process. Nets may be coated only at their knots, i.e. the crossing points of the threads.  In the treatment of knitted stockings, the stockings are preferably covered with a stencil having holes at regular distances apart so that only about 8% of the surface of the stocking is treated with the synthetic resin.  The condensation of the starting materials may take place, when the stocking has been preformed, by drawing it on to a metal former and heating or, if the stocking has not been preformed, the condensation and preforming may take place simultaneously with the application of heat.  The resistance to slipping may be increased by treating the finished products, e.g. nets or knitted fabrics, while held under tension with a solvent mixture, e.g. ethanol-toluene, methylglycol-xylene, or ethylene-glycol-xylene, while heating, or by the action of heat alone.  Threads and filaments of polyesters, polyacrylonitrile, polyvinyl chloride, polyvinylidene chloride and polyamides may be treated.

Title: Heat-recoverable articles
Inventor: EVANS J
IPC: B29C61/06
Filed: 1972-03-29
Abstract: 1383556 Heat-recoverable articles RAYCHEM CORP 29 March 1972 [2 April 1971] 14806/72 Heading B5B [Also in Divisions F2 and H2] A unitary article of polymeric material has two opposite surfaces which are heat recoverable to different extents at a given temperature, the degree or recoverability decreasing with the distance from the surface region comprising the more heat recoverable material so that the film is involutely heat-recoverable, i.e. assumes, on heating, a generally cylindrical configuration with partial overlapping of the opposite surfaces, leading to the formation of a closed spiral. Thus, a film, e.g. of polyethylene or an ethyleneethyl acrylate copolymer may be uniaxially longitudinally oriented and then differentially annealed to provide an orientation gradient, with a region of high orientation adjacent surface 11 and of low orientation adjacent surface 12. The film is then cross-linked in known manner. On heating, the region of high orientation tends to recover and that of low orientation to restrain recovery so that involute recovery takes place, as shown in Fig. 2. A closure device may be made by differentially annealing a molecularly oriented polymeric member 17 at its edge portions 18 and 19 so that edge portion 18 has a region of high orientation above a region of low orientation; vice versa for portion 19. The annealed member is then cross-linked. When the article so made is heated it assumes the shapes of an elongated S (Fig. 5, not shown), and if the arcuate edge portions are interlocked as shown in Fig. 6 and heated further, involute recovery occurs to give an interspiralling separation-resistant seam as shown in Fig. 7; further heating results in radial shrinkage (Fig. 8, not shown).

Title: Improvements in or relating to paper and like sheet folding machines
IPC: B65H45/12
Filed: 1929-05-13
Abstract: 329,161. Shaw, A. V., and Shaw, W. E. May 13, 1929. Folding paper.-In a machine for folding paper or like sheets, a roller is provided to direct sheets into one or other of two alternative paths according to its direction of rotation. In an arrangement of buckling folders g, m and associated rollers, Fig. 1, for imparting parallel folds to a sheet, the roller d associated with the rollers d', d<2> of the buckling-plate g and the roller i associated with the rollers i<1>, i<2> of the buckling-plate m are arranged to be driven in either direction, and to drive the associated rollers frictionally so as to direct the sheet either into the buckling- plates or between the rollers d or i and co-operating rolls d<3> or i<3>. A fixed member h guides the sheet on to the roller i<1> after it leaves the roller d. The rollers d, i have gear-wheels u, p<3>, Fig. 2, respectively thereon. The gear-wheel p' meshes, according to the required direction, with either of two intermeshing gear-wheels p<1> p<2>, the former of which is driven from a gear-wheel p on a. main shaft o. Brackets r pivoted on the shaft o are held in position with either of the gearwheels p<1>, p<2> engaging the gear-wheel p<3> by means of a spring-pressed plunger v engaging holes w in the fixed framing. Brackets s pivoted on the shaft of the gear-wheel p<3> carry gear-wheels t, t<1> which, according to the position of the brackets, can drive the gear-wheel u in either directior.. After leaving the. roller i, the sheets pass through rollers n, n<1> which may slit or perforate the sheets, and are forwarded on to a table 1, Fig. 3, through which a knife 2 folds the sheet transversely into rolls 3, 4. From the rolls 3, 4 the sheet passes to a roll 5 which can be rotated in other direction to direct the sheet either into a buckling-folder 9 or between the roller 5 and a roller 6. Beyond the rollers 5, 6 is a reversible roller 11, so that a sheet passing therethrough may be forwarded either to a blade folder 12, 13 or to a stacker-delivery 16. If the sheet is folded by the folder 9 it may afterwards be fed into the folder 12, 13 or to the delivery 16 according to. the direction of rotation of the roller 11. The sheets from the folder 12, 13 pass into a container 14. The rollers 5, 11 are driven from the shaft of the roller 3 by gearing similar to that shown in Fig. 2. Either of the. blades 2. 13 may be kept, raised out of operative position so that the sheets arriving on the corresponding tables 1, 12 respectively may be delivered without further folding.

IPC: G06F7/38
Filed: 1956-05-12
Abstract: 819,365. Digital electric calculating apparatus. ELECTRIC & MUSICAL INDUSTRIES Ltd. May 7, 1957 [May 12, 1956], No. 14853/56. Class 106 (1). Apparatus for multiplying binary-coded numbers comprises means for producing partial products of one factor with individual digits of the other, means for converting the individual binary digits in each partial product into groups of binary digits such that each group represents a character in a higher notation, and means for summing the partial products. As shown in Fig. 1 a single binary-coded decimal digit multiplicand in a register 2 is to be multiplied by a similar digit in a register 1. The fourcomponent multiplicand digit is set up in each of four staggered rows of saturable magnetic storage cores threaded by horizontal wires XA1 ... XA4 which also pass through cores CD1 ... CD4 to which the four-component multiplier digit is transferred. A succession of current pulses from a distributer 3 clears the cores CD1 . . . CD4, and those storing a significacant binary digit send further pulses on the respective wires XA1 ... XA4 which clear the corresponding multiplicand cores and deliver pulses representing the binary partial products to conversion stores B and C via a drive unit and pulse shaper. Accumulators 10 and 11 receive the units and tens binary-coded digits after translation from pure binary form by the arrangement of storage cores CB1, CB2 ... , CC1 ... CC4 which are cleared to read into the accumulators by two successive pulses from a generator 7. Fig. 2 shows diagrammatically the building up of elementary multipliers M1, M2 . . . &c. of the type described to form a multi-digit binary-coded decimal multiplier. Accumulators P1... P8 are equivalent to the accumulators 10, 11 and the final product is accumulated in a shift store 16 similar in principle to the matrix A in Fig. 1 before being translated to series-mode form under control of a timing device 19.
