Patent DE-4002588-A1 (DE)
Inventor: PLATTE HANS-JOACHIM DR
IPC: H04N11/16
Filed: 1990-01-30
Abstract: In letter-box colour television system additional information is transmitted at a markedly reduced amplitude for reasons of compatibility. This however also reduces the ability to make full use of the maximum attainable channel capacity for the additional information. By transmitting the additional information at full amplitude and by compartmenting or modulating the additional information into a noise-like structure within the boundary regions it is possible to make use of the maximum attainable channel capacity for the additional information with little reproduction interference in the 4:3 receiver. A recognition signal marks the lines with the additional information and makes it possible for an improved 4:3 receiver to black-scan the lines with the additional information. Applications: 4:3 and 16:9 TV receivers.

Patent DE-4035066-A1 (DE)
Inventor: LORECK HEINZ
IPC: H02P3/08
Filed: 1990-11-05
Abstract: Described is a circuit for limiting the cut-off voltage which occurs when an actuator motor (M) is controlled by means of width-modulated d.c. pulses. The circuit comprises a power transistor (T2) which is turned on by a capacitor (C) for a short time interval when a cut-off voltage occurs, thus limiting the cut-off voltage. The transistor (T2) then reverts to the high-resistance state again. This prevents the actuator motor (M) from shorting during the phase in which the motor is reset by spring action to its O-position.

Title: Superfinishing method for groove profile - has swing axis of stone inclined to line of groove to allow simultaneous finishing of full profile
Inventor: SATO CHUICHI
IPC: B24B19/02
Filed: 1990-11-07
Abstract: The Gothic arch groove profiles are used in linear ball bearings as guide tracks for the rollers. After grinding the grooves are finished with a fine stone. The stone (10) swings in the groove (7) about an axis which is aligned at an angle to the line of the groove. In addition to the swinging motion of the stone, it is moved axially in the direction while the nut (6) is rotated about the axis so that the stone traveres the groove. - As the stone swings e about axis it simultan-eously finishes both sides of the groove on the oblique section. The projection on the normal cross-section of the groove is an ellipse which approximates closely to the desired profile. ADVANTAGE- Simultaneous finishing of whole groove profile. Greater accuracy and better surface finish. (4pp Dwg.No.1/13)

Title: Interrogation circuit for capacitative position detector - converts capacitative output current via load resistor into interrogation signal
Inventor: STEFFEN ECKHARD
IPC: G01D5/241
Filed: 1991-01-10
Abstract: The position detector (11) is periodically supplied with a signal voltage, u(t). The load resistor (28) is small in relation to the capacitative impedance of a parasitic time capacitance, CL, dependent on the construction and in parallel with the load resistor. The effect of this capacitance is thus transverse to the measuring capacitance (Cm) in the position detector. The level, p(t) across the small load resistor is high-ohmically interrogated via a read-out amplifier (29). The current, i(t), at the output of the detector is called up by a signal, u(t), having a triangular curve w.r.t. time, t. USE/ADVANTAGE - Interpolated direction, angle or length measruing. Less prone to typical interference effects of capacitative position detector.
