    Abstract: An insulated metallic strip suitable for use in the coils of power transformers and method of producing the same. Following the extrusion of a flat metallic strip of conductive material for winding into a magnet coil, the flat strip having a predetermined thickness and first and second sides bounded by a pair of fully rounded edges, the method of insulating the strip of conductive material by supporting the flat strip in a level state at a predetermined temperature in a vacuum chamber and while in the vacuum chamber applying a liquid coating of resin to the entire first side of the strip and the pair of rounded edges and extending onto the second side of the strip from each of the edges a distance at least as great as about 0.25" to prevent turn to turn discharge. Applying a liquid coating of resin to the second side of the strip at a plurality of spaced areas between the coating extending around the edges, controlling the placement and thickness of the resin coating on the strip and curing the liquid coating of resin. A flat metallic strip of conductive material coated according to this method is also disclosed.

    Abstract: A method and apparatus for applying a coating to a continuous length of tubing. A coating chamber having entry and exit ports substantially encloses a portion of the tubing while permitting the tubing to pass continuously therethrough. Airflow into the coating chamber through the exit port strips excess coating material from the tubing surface. Air is withdrawn from the coating chamber by vacuum pumps through one or more separation chambers which separate entrained particles or droplets of coating material from the air. The coating chamber is preferably disposed at a distance from the separation chamber(s). The vacuum line connecting the coating chamber with the separation chamber(s) is preferably flexible or breakable. The separation chambers are preferably capable of being operated in series or in parallel. Adjustable masks are preferably provided at the entry and exit ports of the coating chamber. A seal is preferably provided at the entry port.

    Abstract: A method for making an electrochemical cell electrode involves depositing a layer of dry carbon/hydrophobic polymer powder on the surface of a substrate by dispersing the powder as a cloud in a chamber over the substrate and pulling the powder onto the substrate by drawing a vacuum under the substrate. The electrode is subsequently compacted and sintered. Typically the carbon component of the powder is catalyzed, such as with platinum. Thus, the method is for applying a catalyst layer on an electrode substrate. The method is particularly adapted to the high speed manufacture of electrodes.

    Abstract: A process for consecutively coating both sides of a continuously travelling web, which comprises coating a first coating solution onto a first side of a continuously travelling web to form a coated layer thereon, supplying a second coating solution while the coated layer on the first side of the travelling web is still in a non-dry state, using a bar which is supported by a supporting member and which rotates in contact with the web in the same direction as the travelling direction of the web in such a manner that a liquid pool of the second coating solution is formed immediately before the position where the bar comes into contact with the web while supporting the first coated side of the web with a pressurized gas, and applying the second coating solution to the second side of the web opposite to the first coated side using the bar.

    Abstract: METHOD FOR IMPREGNATING WOOD WITH A TREATING LIQUID SUCH AS A PRESERVATIVE, A FIRE RETARDANT OR THE LIKE, WHEREIN THE WOOD IS IMMERSED IN THE TREATING LIQUID INSIDE A PRESSURE VESSEL. THE PRESSURE IN THE VESSEL IS BROUGHT UP TO OPERATING PRESSURE WITHIN A SHORT TIME, ON THE ORDER OF TEN MINUTES OR LESS, AND THE CONTENTS OF THE VESSEL ARE THEN SUBJECTED TO THE ACTION OF A PULSATING PUMP WHICH PROVIDES SINUSODIAL PRESSURE PULSES WITHIN THE VESSEL HAVING A POSITIVE PEAK TO NEGATIVE PEAK AMPLITUDE OF FROM 1 TO 1500 POUNDS PER SQUARE INCH. THESE PRESSURE PLUSE ARE MODULATED BY THE ACTION OF A PRESSURE RELIEF MEANS ASSOCIATED WITH THE PRESSURE VESSEL, WHEREBY THE RESULTANT PRESSURE ACTING ON THE WOOD BEING IMPREGNATED CONSISTS OF A SERIES OF PRESSURE PULSES MODULATED IN AMPLITUDE AT A RELATIVELY SLOW RATE. THE TREATING LIQUID WHICH IS DISCHARGED THROUGH THE PRESSURE RELIEF MEANS IN A PULSATING FASHION IS THEN RECYCLED BACK TO THE PULSATING PUMP SO THAT THERE IS A SUBSTANTIALLY CONTINUOUS FLOW OF TREATING LIQUID FROM THE PUMP, THROUGH THE PRESSURE VESSEL, THROUGH THE PRESSURE RELIEF MEANS, AND FINALLY BACK INTO THE INLET END OF THE PUMP.
