Abstract: A closing body is mounted in an axially displaceable manner in a bore of a fluidic valve to control a pressure medium flowing via the valve. The closing body has a sealing section, interacting with a seating edge of valve, and a guide section which serves to guide the valve cone in the bore. The guide section is provided with recesses which allow an overflow of pressure medium between the two sides of the closing body. To reduce costs of production, the guide section of the closing body is of cylindrical form and its surface is provided with at least one helical groove which leads from one side of the guide section to its other side. The closing body is useful in particular in constant pressure valves for controlling fluid pressure medium. The sealing section of the closing body is normally of conical form.

Abstract: Memories are provided for correction signal values respectively for a hue signal, a saturation signal and a luminance signal derived from a digital color television signal. Each of the memories consists of two memory units which are alternately used for storing new correction signal values and for reading out previously stored correction signal values. The corrected signal values are modified by a key signal, if present, in each case and are then supplied to calculation circuits to each of which a signal derived from the saturation signal is applied. The resulting fully corrected hue and saturation signals are converted back into color difference signals, but the finally corrected luminance signal requires no conversion. The raw correction signal values are supplied from a computer into which control magnitudes can be entered to produce them. These control magnitudes can be used to define corner points of a deflected line function from which the correction signals are derived.

Abstract: A digital color television signal has its chrominance component, which is in the form of color difference signals, resolved into color hue and color saturation signals which are used to address a function memory which provides a pair of correction signals that are supplied to calculator circuits which respectively receive the color hue signal, the color saturation signal and the luminance signal as well as predetermined control signals previously stored which relate to the color sectors adjacent to the color sector in which the color hue signal is located. The calculation circuits respectively supply corrected color hue, color saturation and luminance signals. The color hue signal is additively corrected by a color hue correction signal and the color saturation signal is multiplicatively corrected by a saturation correction signal.

Abstract: For picture elements (pixels) having a luminance value in a mid-range of luminance magnitude and a color saturation smaller than a predetermined threshold value a correction signal is obtained by integration of the color saturation value followed by multiplication by the difference between an actual luminance signal and a gradation distorted luminance signal. Threshold values at the boundaries of the mid-range of the luminance signal are determined in a manner dependent upon the extreme values that appear from time to time in the luminance signal. The stored maximum and minimum values of the luminance signals are respectively decremented and incremented at frame intervals until replaced by a new maximum or minimum value establishing a new maximum or minimum.

Abstract: A pinion of a reduction gear intended for use in electronic timepieces having a stepping motor, particularly wrist watches, takes the form of a cylindrical body having an axial blind hole and two teeth milled at one end of the body. The flancs of the teeth are plane parallel surfaces. The distance between the axis of rotation of the pinion and the axis of rotation of a toothed wheel of the reduction gear is slightly less than the radius of the tip-circle of the wheel, so that the two teeth of the pinion block the wheel during the resting period of the motor. If a wheel with 60 teeth is used, it may constitute the fourth wheel in an electronic watch having hands.

Abstract: A cylindrical bearing segment of a preferably metal sleeve is positioned within a hole in a watch-movement plate. A portion of the sleeve intended to project inwardly beyond the plate is divided by a lengthwise slot into two claws which yield so that the sleeve can be inserted in the hole by simple axial pressure. When the dial is to be fitted in place, a dial-foot is inserted in the sleeve, pushing the claws apart by pressing against inner bulges at the ends of the claws, these bulges then pressing laterally against the dial-foot and locking it firmly in place.
