Title: Improved method and apparatus for the manufacture of stamping tools
IPC: B21D37/20
Filed: 1954-11-29
Abstract: 759,460. Stamping dies. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. Nov. 29, 1954 [Dec. 4, 1953], No. 34576/54. Class 83 (4). [Also in Group V] A stamping press having two complementary stamping elements such as a die and punch is characterized in that each element comprises a working surface consisting of a thin, continuous member of uniform thickness made of plastic or synthetic resin and shaped to correspond to the relevant surface of the part to be stamped, e.g. sheet metal components for the aircraft or automobile industries, said member being anchored to a concrete body to form the stamping element. The elements are produced by removably securing a sheet metal pattern 4 (Fig. 1) to templates 2 mounted on a beam 1, providing plaster-retaining means, e.g. countersunk screws 7 and nuts 8, 9 as shown in Fig. 3 on the pattern, coating the pattern with a mixture 33 of plaster and harl and then arranging a metal frame structure comprising members 10 to 14 (Fig. 4) over the plaster. The structure is secured to the plaster by elements 17, 18, 19 of plasterimpregnated harl surrounding uprights 10, 11 and the longitudinal member 16. After the plaster has set the templates are removed and the frame structure with the plaster-coated pattern is turned upside down (Fig. 5) and formed into a mould by providing wooden side boards 20, 21 and end boards (not shown). The metal pattern is cleaned, polished and coated with wex and plastic material, e.g. stratified glass and cold-polymerizing synthetic resin, is moulded, e.g. by spraying evenly over the pattern to form the member 22. A compound moulding may be provided by spraying several layers of resin alternating with glass cloth. The edges 23, 24 and end edges 34 of the member are flanged and Z-shaped ribs 25 of synthetic resin reinforced with glass-cloth are associated with the member 22 to assist in anchoring the member to the concrete body. The end boards (not shown) are provided with apertures for supporting metal reinforcements 26, 27 which carry a plate 28 from which a plurality of screws 29 project upwardly to serve as handling means and attachment means for securing the die or punch to the press slide or base plate. When the concrete has set the complete die or punch 30 is stripped from the mould, cleaned and a lead seating plate 31 mounted on the screws 29. In making the complementary die or punch the pattern 4 is secured to the formed die or punch and the exposed side of the pattern is associated with end boards to form a mould and the plastic layer and concrete casting is applied as hitherto to form the complementary die or punch. Specification 700,709 is referred to.

Title: Improvements in or relating to the production of permanent local embossed effects upon textile fabrics made of cotton
IPC: D06Q1/08
Filed: 1953-12-15
Abstract: Cotton fabrics are pattern-printed with a synthetic resin precondensate or are impregnated all over with the synthetic resin precondensate and pattern-printed with a curing inhibitor; they are then embossed all over, heated to cure the resin and, after rinsing with water, are treated with an alkaline swelling agent which has a swelling action but not a shrinking or parchmentizing action.  The synthetic resin precondensate may be obtained from formaldehyde and urea, thiourea, ethylene urea and its homologues, uron, acetylene diurein and its derivatives, dicyandiamide, melamine, phenol, or phenol derivatives or mixtures of these components, or may be a ketone-aldehyde precondensate and may include an acid or alkaline catalyst, a dye or pigment or compound forming such or a metal powder to produce gold, silver or copper effects.  The swelling agent may be caustic soda of 15 DEG -22 DEG  Be., caustic pot ash of 10 DEG  to 25 DEG  Be., or solutions of zinc chloride or calcium thiocyanate of concentrations up to saturation.  The fabric may be pre-dyed or printed in colours.  In examples, (1) a bleached cotton taffeta is printed with an aqueous composition comprising hexamethylolmelamine, ammonia, ammonium thiocyanate, methyl cellulose and a pigment; after drying at 40 DEG C. and embossing at 200 DEG C., the resin is cured at 114 DEG C. and the fabric is washed, dried and impregnated with caustic soda of 20 DEG  Be., in which condition it is stored for some time; it is then rinsed and stenter-dried; (2) a dyed cotton percale is printed with an aqueous composition comprising hexamethylolmelamine, carob bean meal, ammonia, ammonium chloride and a pigment, dried at 40 DEG C., embossed at 200 DEG C., cured for four minutes at 140 DEG C. and washed and dried in the loose state; it is then impregnated with caustic potash, stored in this condition for fifteen minutes and then rinsed and stenter-dried.  In other examples zinc chloride and calcium thiocyanate are used as swelling agents, a ketone-aldehyde precondensate is used and different colour effects are obtained by vat dyeing or printing.
