Abstract: A method of producing pigskin comprises the steps of sequentially scalding the unprocessed pig carcass in a liquid bath at a temperature of substantially 57.degree. to 59.degree. C. for about 5.5 minutes, removing the carcass from the bath after scalding for 5.5 minutes therein, stripping the hide off the carcass, and singeing the hide. The temperature of the bath is held substantially constant by a microelectronically controlled valve that admits steam to the bath. The carcass is displaced through the bath as it is scalded by a rake- or scraper-type conveyor which holds the carcass wholly immersed while moving it. Thus the carcass is scalded by being immersed at one end of an elongated bath, pushed along the bath, and lifted out of the bath at the opposite end thereof about 5.5 min later.

Abstract: A method of producing glass sheets having good transmission behavior in the visible spectrum range and having good reflection behavior as regards heat radiation. A transparent substrate S is coated by cathodic atomization with, successively, a first oxide layer 1 comprising indium oxide, tin oxide or mixtures thereof, a layer 2 consisting of silver in a thickness of 5 to 50 n, a metallic layer 3 selected from aluminium, titanium, tantalum, chromium, manganese and zirconium in a thickness ranging from 1 to 5 nm and applied directly to the silver layer 2 for the purpose of maintaining the condition thereof, and a final protective oxide layer 4 of indium oxide, tin oxide or mixtures thereof.

Abstract: Solar-controlled glazing having a transmission of between 5 and 40% in the visible spectrum range and having heat-reflection properties is produced by applying an oxide layer having an optical thickness of between 20 and 280 nm directly to a transparent substrate by cathodic evaporation in an oxygen-containing atmosphere to form a first layer. A chromium nitride layer having a geometric thickness of between 10 and 40 nm is then applied in an atmosphere consisting of inert gas and nitrogen to provide a second layer. An optical third dielectric layer may be applied to the second layer. The oxide layer is selected from oxides of tin, titanium and aluminium.

Abstract: High-power cathode system for producing multilayers of different target materials on a substrate has at least two different target materials which abut one another at a boundary line in the field of a magnetic field generator thereof. The substrate is transported for coating across the boundary line, preferably perpendicularly.
