Abstract: The invention discloses an oscillator circuit (100, 200, 300, 400), comprising an oscillating element (110, 210, 310, 410) and output means (115, 215, 315, 415) for outputting an oscillation frequency from the oscillating circuit. The circuit further comprises a signal delay means (120, 220, 320, 420) which is arranged in series with the oscillating element and feeds the output signal back to the oscillating element. The delay means is (120, 220, 320, 420) tuneable with respect to the delay it provides. The oscillating element can be an amplifier or a VCO, and the delay means can be a Delay Locked Loop or a tuneable delay line, depending on the embodiment of the invention.

Abstract: A method of supporting vertically hanging electrical resistance elements for heating furnaces or ovens in industrial operations. Each resistance element includes current-conducting legs that extend downward and upward a number of times, and the element includes along its length a number of ceramic discs that are provided with through-holes through which respective element legs extend. The upper part of the element merges with terminals that are connected to a source of electric current. The element is supported by at least one of the uppermost ceramic discs, wherein the uppermost ceramic disc supporting the element is placed in the insulation of the furnace roof above the underside of the roof. The legs of the element are short circuited at a location slightly or somewhat beneath the underside of the furnace roof with the aid of short circuiting plates.

Abstract: A method of cooling strip or wire products in which, subsequent to being annealed, the product is cooled to a temperature of about 20-50° C. below its oxidation temperature. The product is wound around a drum immediately downstream of an annealing path so that the product lies in mutually juxtaposed turns on the drum. It is thereafter unwound from the drum after a number of turns. The number of turns is such that the product is cooled to a desired temperature. The drum has a diameter that exceeds the diameter at which the product will be influenced mechanically by plastic deformation.

Abstract: An electrical heating element for vertical installation includes vertically suspended electrical resistance elements for the heating of furnaces in industrial operation, where each resistance element is formed of conductive legs, where along the length of the resistance elements are placed ceramic disks provided with holes, through which holes the relevant legs of the element pass. The ceramic disks are arranged between ceramic tubes and an upper metallic central rod is positioned within the ceramic tubes, which central rod supports the element and where the element is surrounded by a radiative tube. There are a number of upper ceramic tubes outside of the upper central rod with intermediate ceramic disks, and the central rod extends a certain distance down into the radiative tube.
