Abstract: 1,149,033. Coating with metals. BADISCHE ANILIN - & SODA-FABRIK A. G. No. 31866/66. Headings C7B and C7F. In an electroless process for coating a plastics sheet with copper or silver in which the plastics surface is first coated with iron powder in a binder, the binder contains at least 20% by weight of a polyisocyanate. The binder may also include vinyl copolymers, polyvinyl chloride, acetal, formal or butyral or soluble polyamide. The coating may be applied through a stencil, and the powdered iron coating may be annealed at a temperature up to 60 C. prior to deposition. A bath for depositing copper may comprise (g./l.) 150 copper sulphate, 40 triethanolamine, and 27 sulphuric acid. A silver layer may be deposited on the copper using a bath comprising 1À5 silver nitrate, 3 E.D.T.A., 3 sodium thiosulphate, and 2 tartaric acid. The copper surface may be electro-plated with a further layer of copper, using the same bath as for the electroless-plating, and then with Cr, Ni, Co or Rh, and the copper or silver surfaces may be electro-plated with Fe, Ni or Co or mixtures thereof.

Abstract: A plastics, e.g. polyester, tape is coated with copper by first coating with a dispersion of iron particles in e.g. polyvinyl chloride, and then passing through a bath of e.g. (parts by weight) 30 copper sulphate, 6 sulphuric acid, 6 tartaric acid, and 6 trimethylaminoacetic acid. A further coating of silver may be applied by passing through a bath of a mercury salt and then an ammoniacal bath of potassium silver cyanide. An electroless nickel coating may be applied to the copper. The iron layer may be applied, whilst subjected to a magnetic field, and to form a pattern e.g. by a stencil. A copper coated plastics tape may be electroplated with Cd, Sn, Au, Ag or Co - Ni e.g. by passing the tape as a cathode through an aqueous solution (pH 5 to 6) of E.D.T.A., cadmium acetate, and HCl or tin chloride and E.D.T.A. or nickel sulphanate, cobalt chloride, and trimethylaminoacetic acid.

Abstract: 1,087,432. Slitting apparatus. BADISCHE ANILIN- & SODA-FABRIK A.G. Jan. 15, 1965 [Jan. 18, 1964], No. 1817/65. Heading B4B. Apparatus for slitting a plastics sheet wound on a spool 55, Fig. 1, into a number of strips, e.g. as recording tape, which is drawn off on to take-up spools 119 comprises a cutter head 52 in which cutters 51, Fig. 2, e.g. razor blades, are clamped together between plates 29 ... 31, Fig. 6, the head being secured to a swinging arm 60 and driven by a motor via an eccentric and connecting rod. A co-operating grooved roller 53 is mounted in bearings on an eccentrically displaced shaft 39 secured on a swinging arm 2, so that it may move backwards and forwards in an arc, and is swung in, by a lever 44, for cutting to commence. A lever 7 effects the cutting movement of the grooved roller, and a lever 12 the swinging movement of the cutter 54 head, the levers being controlled by a disc 14 carrying push-rods 15, 16 in a double eccentric arrangement, driven by a pulley 21. The oscillations of the grooved roller are 90 degrees out of phase with those of the cutter head, so that the cutters in operation move in an endless curve in continuous relative movement with respect to the sheet being slit, so that the point of cutting on the cutting edge is continuously being changed. The take-up apparatus for the spools 119 comprises a hollow shaft 121, Fig. 5, and a main shaft 101 arranged so that when the thickness of the tape to be severed is constant the shafts run at the same speed, but may be compensated for different thicknesses of tape by changing the speed. Both shafts are driven by a pulley 101 via clutches 108a, 108b by belt drive from a variable-speed motor. Up to four tapes may be wound simultaneously on each shaft. The tape is cleaned before being wound up, by duster rollers, blowing or suction.
