Filed: 1920-10-26
Abstract: 153,575. Allen & Co., S. L., (Assignees of Allen, C. J.). Nov. 7, 1919, [Convention date]. Adjusting parts of implements; frames for implements; steering implements; motor implements; cultivators.-In tractors, more particularly of the kind in which the power unit is carried on a pair of driving and steering wheels, the trailing im plement or vehicle being connected with a pivoted tail beam, the beam is mounted so as to oscillate about its horizontal axis relatively to the yoke to which it is connected. The yoke 8 is mounted on vertical pivots on the main frame and is fitted with a bracket comprising upper and lower members 41, 42 connected by integral end webs 43, 44 forming bosses 45, 46. Between the bosses 45, 46 a skeleton block 50 is mounted on a pintle 48, the tail beam members 25 being bolted to the block. By these means an implement attached to the tail beam will have free movement with respect to the tractor in a transverse plane. As shown in Fig. 1, the implement is towed by means of a link 60 adjustably connected to a removable bracket 15 and is rigidly connected with the beam by means of a strap 77 bolted to a U-shaped member 75 bolted in turn to the beam. In the case of implements in which the draw-bar is high, the connexion is made to the block 50 and the implement is connected with the beam at two points by means enabling a forwardly tilting adjustment to be effected. For this purpose, the front of the implement is connected with the beam by means of an adjustable screw, the rear being provided with an upstanding horizontally slotted member riding on a pin between the sides of the beam to permit a slight horizontal movement. The steering and controlling members are mounted on a standard 36 and brackets 28 which may be bolted to the beam in different positions to bring them within convenient reach of the driver.

Abstract: 811,637. Agglutinated fibrous materials. DU PONT DE NEMOURS & CO., E. I. Oct. 24, 1955 [Nov. 2, 1954], No. 30379/55. Classes 96 and 140. A reinforced flexible plastic sheet material comprises a pre-formed non-woven web of polymeric synthetic fibres as hereinbelow defined, bound together with a subsequently applied elastomeric composition comprising a copolymer containing 85 to 40 per cent by weight of butadiene and 15 to 60 per cent by weight of acrylonitrile. Polymeric synthetic fibres which may be used are fibres of nylon, polyacrylonitrile or polyethylene terephthalate or mixtures thereof. The process of preparing the sheet material of the invention comprises forming a web of non-woven staple polymeric synthetic fibres, placing a composition comprising a copolymer containing the butadiene and acrylonitrile in contact with the web and subjecting the assembly to heat and pressure sufficient to cause the copolymer first to fuse and permeate the web (but insufficient to melt or fuse the fibres) and then to be cured to form an elastomeric copolymer. The heat and pressure may be applied by passing between heated calender rolls or by pressing between heated plates. When brought in contact with the web the copolymeric binder may be in the form of a preformed film, or in particulate form, or dispersed in an aqueous solution. Examples describe subjecting to heat and pressure (a) a nylon web and a film of butadiene acrylonitrile copolymer; (b) several nylon webs dusted with the copolymer in powder form; (c) a waterleaf of polyethylene terephthalate fibres impregnated with the copolymer in methyl ethyl ketone ; (d) a web of polyacrylonitrile fibres impregnated with an aqueous latex of the copolymer; and (e) an assembly of superposed alternating webs of polyacrylonitrile fibres and copolymer films.

IPC: A43D25/06
Filed: 1968-06-28
Abstract: 1,169,864. Boots, &c. J. S. KAMBORIAN, 28 June, 1968 [18 July, 1967], No.30943/68. Heading A3B. A method of effecting temporary attachment between a relatively porus surface e.g. of an insole 10, and a relatively impervious surface e.g. of a last 12, while an operation is performed on the insole 10 e.g. lasting an upper to the insole 10, comprises applying to at least one of the surfaces one or more plugs 14, 16, 18 of delayed tack cement, pressing the surfaces against each other while the cement remains tacky to cause the cement of each plug 14, 16, 18 to penetrate the porous insole 10 and adhere thereto by a mechanical interlock and to adhere to the impervious last 12 by surface adhesion, and removing the insole 10 from the last after a lapse of time sufficient for the cement to have ceased to be tacky, so causing each plug 14, 16, 18 to become separated from the last 12 and remain adherent to the insole 10. The insole 10 is applied to the last 12 using the apparatus described in Specification 1156281. The delayed tack cement is a mixture of a thermoplastic resin and a crystalline plasticizer and is applied to the last 12 and insole 10 in a molten condition. The cement remains in a tacky and fluid condition for a period of time after application to the insole 10 and last 12, after which the plasticizer crystallizes and the cement loses its tackiness and fluidity and thus terminates the surface adhesion between the cement plugs 14, 16, 18 and the last 12.
