Title: Method and machine for welding with driven electrodes
IPC: B23K11/06
Filed: 1966-12-21
Abstract: A welding machine having one or more driven electrodes arranged to move work forwards is provided with means for accelerating the work before the work enters the welding station to a velocity corresponding to that of the electrode or electrodes. In an embodiment the machine comprises a fixed lower arm 3 carrying a roller electrode 9 and a pivoted upper arm carrying a roller electrode 7, electrode wires passing over the roller electrodes being driven by rollers 41, 57. Rails 13 on the arm 3 support a carriage 11 having a holder 15 for the work and a belt 17, connected to the frame of the machine and the carriage, normally urges the carriage to its position shown in Fig. 1. An abutment 19 on the carriage engages a buffer 21 on a bar 23 adjustably secured in a tube 25. The tube 25 carries a control member 29 controlling a limit switch 31 and an abutment plate 35 for movement between two stops 33, 36 fixed to the machine frame. A control bar 37 of triangular crosssection is secured to the plate 35 and is arranged between a roller 43 movable vertically by a piston/cylinder device 47, 49 and the roller 41 for driving the lower wire electrode. With the machine in its start position as in Fig. 1, the work (sheets 59, 61) are secured to the carriage 11 spaced from the rollers 7, 9, the plate 35 contacts the stop 36 and the bar 37 is spaced from the wire driving roller 41. The upper arm 5 is lowered to bring the rollers 7, 9 together and when welding pressure is obtained the rollers 41, 57 drive the wires 53, 55. When the welding pressure is reached air is forced through a conduit 51 to raise the roller 43 and thus the bar 37 against the roller 41. The bar 37 and thus the carriage 11 is moved towards the rollers 7, 9 the plate 35 strikes the stop 33 and the carriage continues towards the rollers 7, 9 to advance the work between the wire electrodes and roller electrodes. The welding current may be reduced to 50-80% e.g. 70-75% of normal as the work initially comes between the roller electrodes and as it leaves the electrodes.

Title: Process and Devices for the Continuous Finishing of Textiles
IPC: D06B19/00
Filed: 1967-07-08
Abstract: Fabric comprising cellulosic and/or synthetic fibres are continuously padded with a liquor containing a heat-curable synthetic resin, squeezed and cured optionally after drying, by drawing through a sufficient volume of a heated gas, e.g. heated air, steam, or an air/steam mixture at 140 -190 C., at such a rate as to cure the resin without causing migration thereof in the fibres. The fabric is thereby rendered stiff, crease-resistant, shrinkproof or water-proof. The fabric may be woven, non woven or knitted and may contain cotton or viscose rayon fibres. The heatcurable synthetic resin may be an etherified melamine-formaldehyde condensate and the impregnating liquor may also contain a catalyst e.g. zinc chloride, softener aurea-formaldehyde condensate, filler, water-repellent, e.g. paraffin or silicone emulsions, optical brightener or other auxiliary agent, e.g. a starch product, cellulose ether, polyvinyl alcohol, polyacrylamide or partially saponified polyvinyl acetate. The fabric may be supported by sieves e.g. sieve drums which may be covered with a seamless fine wire mesh on which the fabric rests, which serve as carrying and conveying elements, the heated gas being passed through the fabric in such a way that it is forced against the sieves. Drying and curing may be done in a single process on the sieve drums or curing and fibresetting of the synthetic fibre portion may be done in a single process. In Fig. 1 fabric 1 leaving a last wash bowl 2 is squeezed in squeezer 3, impregnated with the liquor containing the heat-curable synthetic resin in suction drum bath 4, squeezed in squeezer 5 and guided by creel 16, guiding device 17 and rollers 18 to drying and setting device 6 having a heat insulated housing subdivided by means of a lengthwise partition into a treatment chamber and fan chamber, the sieve drums 11 in the treatment chamber provided as conveying elements on which the fabric is guided alternately and penetrated by heated gas. The suction draft is interrupted at those drum portions which are not covered with fabric by means of baffles 12 so that the whole volume of recirculated air is passed through half the drum jacket and through the fabric. A fan wheel is correlated to the faces of the sieve drums in the fan chamber, the air sucked out of the drum being blown by the fan wheel into heater batteries arranged above and beneath the fan wheel so that it is heated again and returned to the treatment chamber where it is slightly retained by sieve sheets 15 and equalized before it is returned to the sieve drum. The fabric is then passed to conditioning compartment 19 where it is cooled down and provided with a certain residual moisture content, and by means of plaiting device 21 is packed on to wagon 20. The drive of rollers 18 is infinitely variable independent of the sieve drum drive so that the fabric may be passed to the first drum 11 with overfeed so that if it shrinks during the treatment there is no tension on the sieve drums.

Patent ES-369064-A1 (ES)
Title: Gold deposition
IPC: C23C14/34
Filed: 1969-07-02
Abstract: Gold is sputtered on a substrate of metal or an insulating material, the target cathode being electrolytically coated with an alloy consisting of gold and a small amount of a metal which is capable of forming a compound by reaction with molecular oxygen. The metal alloyed with the gold may be Co or Ni, the substrate may be Ti, Ta, Cr, Mo, a ceramic, quartz, ferrite, or glass and the target may be of steel coated electrolytically with the gold alloy. Two methods of sputtering are disclosed. Where the substrate permits diffusion of metal thereinto, the deposition apparatus is evacuated to 10<-6> Torr, flushed with argon, reevacuated, and sputtering is started so that an intercrystalline adhering layer is formed on the substrate which layer becomes subsequently coated with the gold alloy layer. Where the substrate does not permit of diffusion the vessel is evacuated to 10<-3> to 10<-4> Torr, and the procedure described above is followed, except that a little oxygen may be added to the Ar. This gives rise on subsequent sputtering to a substrate coated with, in order, a cobalt oxide layer, a cobalt oxidecobalt-gold layer, and a final thicker coating of Au-Co.
