Title: Pressure-medium-operated disengaging device for clutches, especially for motor vehicle clutches
Inventor: HUBER LOTHAR
IPC: F16D25/08
Filed: 1982-09-15
Abstract: A clutch disengaging apparatus wherein an annular cylinder defines an annular cylinder chamber receiving a reciprocable annular piston with an annular outer clearance surrounding the outer skirt of the piston and an annular inner clearance surrounding the inner skirt of the piston. A membrane overlies the bottom wall of the piston and its marginal portions are clamped between the sections of the cylinder so that the membrane forms an outer corrugation in the outer clearance and an inner corrugation in the inner clearance. A throw-out bearing is radially movably mounted in the piston and is biased against the prongs of the diaphragm spring in a clutch by a coil spring which is surrounded by an inner wall of the cylinder, which surrounds an outer wall of the cylinder, or which is installed in the cylinder chamber between the bottom walls of the piston and the cylinder. The piston is guided against radial movement with reference to the cylinder by a tubular guide member which is connected to or forms an integral part of the inner wall of the cylinder and is tracked by one or more followers of the piston.

Title: Television receiver with digital AGC
Inventor: STECKLER STEVEN ALLAN
IPC: H03G3/20
Filed: 1985-10-30
Abstract: An automatic gain control arrangement is provided for the input to an analog to digital (A/D) converter 50 in a television receiver signal processing system. A gain controlled amplifier 40 applies an analog television signal to the input of the A/D converter. The A/D converter produces digitized signal samples at an output which is coupled to a digital peak detector 44 which is selectively activated during recurrent synchronizing intervals of a received television signal. The detector 44 detects the amplitude peaks of the digital samples. The detected amplitude is compared in a comparator 110 with a desired value or range of values. If the detected amplitude is not at the desired level or is outside the desired range, a signal is generated which is applied as a control signal (VAGC) to the gain-controlled amplifier 40 to control the level of the analog signal applied to the A/D converter. <IMAGE>
