Patent DE-3927101-A1 (DE)
Title: Video signal contained luminance signal processing - averages non-delayed and delayed luminance signals only when they differ by preset delay value
Inventor: REIME GERD
IPC: H04N5/21
Filed: 1989-08-17
Abstract: A non-delayed luminance signal (A) and a delayed luminance signal (T) are halved to form a processed output signal (D). The average forming halving is carried out only, when the two luminance signals differ by less than a preset value. The processing circuit contains a delay member (11) for the luminance signal delay by one line period (1H). An adding member (12) adds the delayed luminance signal to an undelayed one and transmits an addition signal (C). A first pass threshold circuit between the delay member outlet and the adding member outlet and a second such pass threshold circuit between the underlayed luminance signal line and the adding member output complete the circuit. USE/ADVANTAGE - For TV transmitters, video cameras, or video recorders, with increased level of luminance signal and thus brighter image.

Title: Device for weighting of horizontally divided sand moulds - comprising metal wt. placed on top of mould and attached by pivoted overlapping arms to side plates which rest against mould
Inventor: MORTENSEN ANDERS
IPC: B22C23/00
Filed: 1990-02-21
Abstract: The device consists of a flat metal wt. element which rests on the top of the mould, and a clamping plate on either side of the mould. The base of the mould rests on a transport system. At least one L-shaped arm is connected by pivoting joints between the weight element and each of the side plates.

Title: Making cord for tyre bead reinforcement -  by disposing warp threads of cord in normal direction, introducing cord wefts at acute angle, rubberising, and cutting strips obliquely
Inventor: JARKE UTE
IPC: B29D30/38
Filed: 1990-08-28
Abstract: The cord for use in making tyres, and the type bead reinforcement in particular, is produced by making a fabric from warp and weft of textile cords, rubberising it, and dividing it into set strips cut at an angle; in the process the wefts are inserted at a weft angle into the warp, where that angle runs obliquely to the warp threads. The cord fabric differs from the usual. Its warp threads are arranged in the conventional manner i.e. they lie in the direction (x-x). The weft cord however, are set at an accute angle into the warp; in the case shown the weft angle is 60 deg. C to the direction (x-x). The prod. is this a bias weave. It is cut into cord strips of a suitable width. ADVANTAGE - The method reduces the number of layers of the bead reinforcement whilst retaining the effectiveness of its cord layer by the angle of the cords to the carcass which has been proved by experience.

Title: Efficiently drying washing using program-controlled drum dryer - with heating phase, with constant speed, phase with declining speed
Inventor: KLUG HANS-JOACHIM DIPL ING
IPC: D06F58/30
Filed: 1990-10-10
Abstract: Drying washing in a program-controlled drum dryer and involves circulating the washing through rotating the laundry drum. The drying process is subdivided into a heating phase, a phase with a constant drying speed, and a phase with a declining drying speed. The drum is reversed during the drying process. During the heating phase and the phase with a constant drying speed, the reversing of the laundry drum is carried out with a counter rotation that is significantly shorter than the main rotation with the heating connected permanently. In the phase with a declining drying speed, the duration of the main and the counter rotation is extended significantly and the heating is switched off during the counter rotation of the drum. ADVANTAGE - Energy is utilised more efficiently and the overall drying time is cut.
