Filed: 1985-07-12
Granted: 1989-04-20
Abstract: In a circuit arrangement for feeding electrical users with a DC voltage, a control circuit of a first switch controller serves as a current/voltage converter supplied from an auxiliary voltage source. Given such circuit arrangements, the auxiliary voltages should be generated with the simplest possible means and should be available as quickly as possible upon turn-on. For this purpose, the auxiliary voltage source is formed by a second switch controller whose switch element is parallel to an input of the first switch controller to which a capacitor is connected via a diode. Furthermore, the first and second switch controllers are positioned in series with one another at the input. The circuit arrangement can be advantageously employed in intermediate stations of communication transmission devices having DC current series feed.

Abstract: a A narrow bandwidth analog-to-digital conversion (ADC) system is described in the context of the color burst processing and burst phase detecting circuitry of a digital color television receiver. The ADC (14) includes a dither generator which adds a dither signal to either the analog input signal (10) or to the reference signal (38) used by the ADC. This dither signal increases in magnitude by 1/16 of an LSB value at a rate one-quarter of the burst frequency and changes in sign at one-half of the burst frequency. This signal passes through a low-pass filter (18) in the chrominance channel providing an increase in sample resolution by averaging the samples in a chroma band-pass filter and in the phase detecting circuitry (30).

Abstract: In a method of mixing two or more gas flows, the gas flows are passed through an array of at least three parallel adjacent guide conduits so as to emerge from said conduits into a mixing zone as a corresponding array of parallel adjacent streams flowing in the same direction. The gas flows are distributed alternatingly in said conduits so that each said stream has, as each of its neighbours, a gas stream from a different said gas flow. To improve mixing and shorten the required length of the mixing zone, the streams derived from the respective gas flows have different velocities at their emergence from the guide conduits into the mixing zone.
