Title: A process for the production of glossy metal-like surfaces on carrier materials
IPC: D06Q1/04
Filed: 1965-09-07
Abstract: A surface resembling that of a metal foil having a high gloss is produced on a web of a carrier material such as paper, cardboard or a film by applying to the carrier material a coating composition containing not more than 30% of a subdivided metal in platelet form dispersed in an organic binding agent, passing the web over a heated moving surface having a high gloss with the coating of the web in contact with the said surface while avoiding relative movement between the carrier material and the said surface, and drying the coating while it is in contact with the surface.  Metals mentioned are copper or aluminium bronzes. Suitable binding agents are vegetable or animal products such as starches or casein, or dispersions or solutions of film-forming plastics, or mixtures of natural and synthetic products.  The heated moving surface may be the surfaces of a rotating metal cylinder having a high gloss produced say by a coating of dense, pore-free chromium plating.  In the Example, a coating composition comprising finely-divided gold in platelet form, casein, a polyacrylate, a wetting agent, sulphated caster oil, caustic soda, trisodium phosphate, tributyl phosphate, sodium stearate and water at pH 9.5-10, was applied by rollers or a doctor to medium strength, sized paper.  The coated surface of the paper was then immediately fed on to a chromium plated rotating cylinder heated to 90 DEG C and pressed thereon by rubber rollers. After the coating had dried, the paper was removed from the cylinder.

Abstract: 1,059,065. Power regulation of diesel electric locomotives; control of D.C. motors. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI (ACEC). Sept. 8, 1965 [Sept. 9, 1964]. No. 38401/65. Headings H2H and H2J. In a diesel electric locomotive, the power supplied from a D.C. generator 2 to traction motors 3 is automatically adapted to the maximum power available at the diesel engine 1 irrespective of the speed of the latter. Excitation for the generator 2 is supplied from an alternator 13 (driven by the engine 1) through a magnetic power amplifier 12 controlled by a transistorized regulator 11 having an input from a function generator 10, which input represents the ideal mechanical power of the engine 1. The generator 10 is supplied by three voltage signals respectively representative of the position of the engine fuel injection pumps, the scavenging pressure of the engine and the speed of a tacho-generator 9 driven by the engine. A speed governor 4 is controlled from the driver's cab and acts on a fuel injection device 5 which determines the angular position of the rotor of a synchro device 7 supplying the generator 10, the "scavenging" voltage being obtained through a pressure transducer 8. The regulator 11 is also fed from transducers 14. 15 with signals respectively representative of generator current and field excitation, so that the current is progressively limited according to a linear law for each engine speed as a function of the generator voltage, and so that the generator voltage is maintained substantially constant for each engine speed. The regulator 11 is also supplied from a mixing circuit 18 fed with a voltage from a potentiometer 16 adjustable in the driver's cab and with a voltage from each of a number of tacho-generators 17 driven by the axles of the locomotive, an increase in the speed of any one of the axles relative to that determined by the setting of the potentiometer 16 producing a control voltage in the regulator 11 which reduces the excitation and hence the power output of the generator 2. Typical voltage/current characteristics are given for a range of engine speeds, Fig. 2 (not shown). Further signals may be fed to the regulator 11 to produce braking and other automatic control.
