Title: Circuit arrangement with an integrated circuit.
IPC: H03L1/00
Filed: 1982-05-28
Abstract: A circuit arrangement includes an integrated semiconductor circuit with a plurality of connection leads in which stray capacitances with equal temperature coefficients exist between one connection lead and the two adjacent, second and third, connection leads. A voltage is present between the first and second connection leads, and produces a current through the stray capacitance between these connection leads. In order to cancel the effect of this temperature-dependent current, a compensation voltage is applied between the first and second connection leads, which compensation voltage causes a current which is equal and opposite to the current through the stray capacitance between the first and second connection leads to flow through the stray capacitance between the first and third connection leads.

Patent ES-8306949-A1 (ES)
Title: Signal gain control with DC compensation
IPC: H04N5/53
Filed: 1982-08-20
Abstract: The DC output level of a video signal amplifier is compensated to remain constant as the amplifier is gain controlled in response to a gain control voltage supplied from a gain control circuit which also supplies a DC compensation voltage to the amplifier. The DC compensation is preserved by means of an additional network which senses the DC bias of both the amplifier and the gain control circuit, and corrects a deviation of the amplifier bias and the gain control circuit bias from a prescribed mutual relationship. The sensed DC bias of the gain control circuit is also used to establish a black reference level for the video signal.

Title: Mill for fluid milling material.
IPC: B02C17/16
Filed: 1983-11-15
Abstract: A ball mill stator providing a milling space between a housing and a cover and a ring-like displacing body in the milling space with a V-shaped radial cross-section forming part of the rotor. The material being milled together with the balls flows around the displacing body from a feed inlet to an outlet along spiral paths. The milling media kept back at the milling gap are moved through a duct into an annular space and from this point through conveying ducts of an impeller outwards and re-enter the milling space at a small distance above the feed inlet. The impeller is sealed between the rotor and stator and is powered by a motor, or by a variable speed drive, run at a speed controlled by readings taken from different parts of the mill system such that the milling media is evenly distributed in the material being milled by which they are moved along making the milling operation more uniform and efficient. An adjustable milling ring together with the impeller form a coarse milling unit whose gap size may be changed like that of the inlet.
