Title: Improvements in or relating to the heeling of shoes
IPC: A43D79/00
Filed: 1941-09-12
Abstract: 552,565. Heel-attaching. BRITISH UNITED SHOE MACHINERY CO., Ltd., CARR, J. W., and CLARKE, T. B. Sept. 12, 1941, Nos. 11679/41 and 6535/42. [Classes 17 (i) and 17 (ii)] Relates to methods of attaching a heel built up of a plurality of lifts to a shoe comprising so inserting into one of the parts a plurality of nails, free from collars or like means, that portions are left protruding from said part for entry into the others part, and thereafter pressing together the parts so that the protruding portions of the nails enter the other part. The nails are, preferably, pointed at both ends, are formed with shallow helical grooves of steep pitch and are roughened or pitted. Preferably, they are driven into the heel seat and their heel ends clenched against a last plate. While the nails are driven into the heel seat pressure is maintained between the nailing die 17 and an abutment plate 21 to prevent "gaping" at the junction of shoe and heel. Holes are made in the heel for the reception of the nails. Specifications 22839/02, 24545/06, 24545A/06, 24546/06, 25040/08, [all in Class 17, 420,293, 451,410, 522,417 and 525,959 are referred to.

Abstract: 966,233. Inflatable shoots. GARRETT CORPORATION. March 30, 1961 [March 30, 1960], No. 11816/61. Heading B8B. A collapsible pneumatic safety shoot 100 includes a slideway 16 carried by inflatable longitudinal beams 20 connected at 21 and 22. The beams also support side tubes 18 which act as arm rails when the passenger escapes from aircraft 10 by sliding down slideway 16. The shoot is blown up by air from cylinder 26. The air proceeds through pipe 27, draws in more air from the atmosphere through aspirator 28, enters side tube 18, then passes through holes 24 into beams 20 and through holes 24 into the other side tube 18. Relief valve 36 limits the pressure of air. The pressure of air may be such that when the passenger slides down the slideway 16 the shoot bends when he reaches the bottom to assist his landing. The shoot is secured to the aircraft by a sheet 30 detachably secured at 31 and is additionally carried by straps 32. It also carries loops 38 and handles 40. Specification 788,638 is referred to.

Abstract: 247,433. Suits, S. May 6, 1925. Designs. producing; shearing.-In machines for cutting designs in compressible sheet material such as pile fabric and of the kind in which a roll presses portions of the pile into depressions in a design roll for severance by a knife, the presser roll 3 is adjustably mounted and is pressed towards the design roll 1 by a yieldably mounted driving-roll 29. The rolls are geared to have the same peripheral speeds. The portions of pile pressed into the depressions 2 of the roll 1 are severed hy a band knite 6 arranged to make an obtuse angle with the line joining the centre of the roll 1 and the point of greatest compression of the pile. The knife is kept sharp by engagement with grinding wheels. The severed pile is removed by a suction device 52 the lower edge of which is near the point of severance of the pile. Suitably arranged driving gear is provided for allowing the roller 1 to be changed for one of a different diameter. The driving roller 29 is mounted on arms 32 pressed by springs 36 engaged by eccentric rods 35. A cradle 40 carrying rolls to prevent the roll 29 from sagging is pivoted to levers 41 mounted on springs 45, the ends of the levers being engaged by other eccentrics. By rotating a lever 39 the eccentrics may be turned to release the pressure of the roll against the presser roll 3, and thereby to allow the material to be inserted in the machine.

Patent GB-1091935-A (GB)
Title: Method of manufacturing leather substitutes and a product of the same
IPC: D06N3/12
Filed: 1965-03-22
Abstract: A leather substitute is manufactured by preparing a coating solution by admixing a 5 to 50 per cent by weight solution of at least one polymer containing at least 60% by weight of polyurea elastomer, the solvent being miscible with an alcohol and water but being a nonsolvent for polyamide, with a 5 to 25% by weight alcoholic solution of a polyamide in the dry weight ratio of 1:1/20 to 1, coating the colloidal or suspended admixture thus obtained onto a fibrous substrate, and subsequently treating the coated substrate by immersion in water to form a product having a microporous coating. Again, the leather may be produced by mixing solutions of a polyurea elastomer and a polyamide, each in a solvent for it but non-solvent for the other, the solvents being compatible with each other and also miscible with water, applying the suspended admixture on to a fibrous substrate, which may be pretreated with polymer, and subsequently immersing the coated substrate in water to coagulate the coating. The polyurea elastomer may be obtained by reacting a reaction intermediate of a polyalkylene ether glycol or polyester-glycol having an average molecular weight of 400 to 5000 and an excess of an organic diisocyanate with an organic diamine.  The solvent for the polymer may comprise N, N-dimethylformamide, N, N-dimethyl acetamide, dimethyl sulphoxide, or tetrahydrofuran acetonitrile.  The polyamide may be a copolyamide, e.g. of nylon 6 and nylon 6, 6, or a N-alkoxymethylated polyamide.  The alcohol may comprise one, or mixed alcohols, selected from the lower aliphatic alcohols having 1 to 6 carbon atoms.  The polyurea elastomer may be mixed with up to 40% of a compound which is compatible with the polyurea elastomer and is substantially soluble in the solvent for the polyurea elastomer, the compound may be a vinyl polymer or copolymer selected from polyvinyl chloride, polyacrylonitrile and a copolymer of vinyl chloride or methacrylonitrile and acrylonitrile, cellulose acetate or acetate-butyrate, epoxy resin or nitrile rubber.  The solution of polymer containing the polyurea elastomer may be admixed with water or alcohol, or a mixture thereof, or alcohol in the form of solvent for polyamide to obtain a substantially colloidal or suspended solution.  The fibrous substrate may comprise a fabric, a non-woven fabric, a mat, and/or paper, or a non-woven mat previously treated with a solution or emulsion of an elastomer or synthetic resin such as a polyurea, polyacrylic or acrylonitrile-butadiene or chloroprene rubber, e.g. by impregnating it with a solution of an elastomer, the elastomer being coagulated in a liquid which is a non-solvent for the elastomer and is miscible with the solvent for the elastomer.  The polyamide solution may have a content of calcium chloride in a concentration of 5 to 25% by weight.  The leather substitute may be embossed and then spray coated or dressed by means of conventional procedures.
