Title: Improvements in the production of patterns on textile fabrics
IPC: G03C1/76
Filed: 1945-12-13
Abstract: 597,982. Coloured patterns on textile fabrics. BLEACHER'S ASSOCIATION, Ltd., FARRINGTON, F., STUBBS, A. E., and HALL, E. Dec. 13, 1945, No. 33735. [Class 98 (ii)] Coloured patterns on textile fabrics are produced by impregnation or coating the fabric with a light-sensitive ferric salt and a vat dye, exposing to light in selected areas, treating with alkali to convert the ferrous salt to a form which reduces the vat dye to a leuco form and causes it to be absorbed by the fabric, causing such absorbed leuco dye to oxidize, and washing out unreduced vat dye and iron salts. Alternatively, the dye and an alkaline solution may be applied to the exposed fabric. The ferric salt may be ferric ammonium citrate, oxalate or tartrate, or ferric glycollate. The ferric salt and dye may be applied together or separately, and impregnation may be replaced by spreading or by printing on localised areas a paste of ferric salt and dye. The exposure to light may be effected through a stencil or photographic transparency. The colour may be brought out by the use of an oxidizing bath, or atmospheric oxidation permitted. In an example, cotton fabric is padded in an aqueous suspension of Caledon Jade Green X 300 paste, dried, padded in a solution of ferric ammonium sulphate, ammonium citrate and ammonia, dried, exposed to light under a negative, treated in aqueous caustic soda solution, rinsed, treated in hot oxalic acid solution, rinsed, washed in boiling soap solution, rinsed and dried.

Abstract: 486,961. Finishing shoes. DODGE, M. L. Dec. 14, 1936, No. 34323. Convention date, Dec. 30, 1935. [Class 17 (i)] To' remove wrinkles from a shoe upper, the side walls are subjected to pressure between opposing forms engaging the upper substantially to the sole and from the heel forwardly through the waist. The inner form is heated, and, preferably, also the outer forms. A form 1, inserted in the shoe, is divided longitudinally, and each half is hinged to a bracket 10. When the two forms are closed together, their meeting faces remote from the hinge are recessed at their lower sides to provide parallel faces between which is a square cam on a shaft 22 which is rotated to expand the form. Co-operating with the form 1, to engage the outer side of the shoe, is a form 45 adjustably clamped to a pivot 51 secured in a shaft 56 rotatable in ears in a bracket 55 pivoted at 60 and urged by a spring 62, to a limit determined by a stop 63, so that the lower edge of the form will engage the upper first, and, as the whole form reaches the pressing position, it will wipe the upper heightwise away from the sole. Each half of the inner form is heated by an electric resistance. The outer form, if not heated, is cushioned on its shoe-engaging face with rubber provided with a leather cover. If this form is heated, the cushioning is omitted. The bracket 55 is carried at the upper end of a lever 40 pivoted at 41 and actuated, with its corresponding lever for the form on the other side of the shoe, by a pair of links 39 pivoted to a vertically sliding rod 36 linked to a handle 34. In order that the two halves of the form I may be expanded while the forms 45 are closing on the shoe the shaft 22 is continued as a twisted fin 93 engaging a rectangular slot at the upper end of a cap 90 secured to the upper end of the rod 36. In a modification, the cam is turned by a handle which can be secured in any desired position: In a modification, the forms move in straight paths toward the shoe, the levers 40 being substituted by arms 105 sliding on guide rods 106, 107, urged outwardly by springs 108, 109 and moved inwardly by levers pivoted at 111. In another modification, the outer forms are moved against the shoe by hydraulic mechanism. Each form 195 is carried on a pivot 182 on an arm 173 pivoted in a piston 171 in a hydraulic cylinder 180. The arm 173 is urged rearwardly and held against a stop 175 by a pair of springs 177 one on each side of the cylinder. Each cylinder is carried on a plate 152 pivoted at 151 and also carrying the corresponding half of the inner form, the assembly being expanded by a handle 161. The cylinders are supplied with oil by pipes 200 communicating with a cylinder 206 having a piston 207 operated by a rod 208 adjustably secured to the end of a lever 211 provided with a latch 218 co-operating with recesses 219, 220 for maintaining it in either of its extreme positions.

[Also in Divisions C7, D1, F1, F2, G3 and H2] A device for supporting a moving filament 13 by means of a fluid cushion comprises two plates 1, 2, separated by a spacer 3 which extends partially around a recess 10 in the face of one of the plates to which fluid is supplied under pressure, to form the cushion, via an opening 11 through the plate. In a wire annealing apparatus, the device supports a filament which passes over an electrically conductive pulley 111 which is rotated by an air turbine having blades 114 attached to the pulley and a nozzle 115 which directs air on to the blades. The supply of air to the nozzle is controlled by a valve 122 which is adjusted by a diaphragm 121 which moves in response to variation in the pressure of air in the guiding devices 118, 119 on either side of the pulley so that if, e.g., the tension T2 increases, the filament 112 moves towards the inlet to the guiding device 119 causing the pressure P2 to increase, thereby lifting the diaphragm and opening the valve 122 to admit more air to the nozzle, thereby increasing the speed of rotation of the pulley. The pulley may be supplied with electricity via mercury brushes 123. The pulley may be driven by an electric motor instead of the turbine, the diaphragm being coupled to the wiper of a potentiometer which regulates the power supplied to the motor so that the tension in the filament may be adjusted. The fluid cushion device is also suitable for guiding plastics filaments and magnetic tapes.
