Title: Video recorder with digital storage optical video tape calibration settings - uses static RAM to store test tape video tape parameters for re-recording and further replaying
Inventor: DUMONT FRANK DIPL ING
IPC: H04N5/931
Filed: 1991-06-06
Abstract: Test tape (1) parameters from the tape head (2) are amplified (3) and passed to a bandpass filter (4), a rectifier (7) and a microprocessor (11). The filter path signals are fed to a FM demodulator (5) to produce the BAS signal (6) while the rectifier path signals are amplified (8), digitised and stored on a static RAM under control of the microprocessor. When replaying the BAS signal is frequency modulated (14) and then pre-emphasised and amplified using control signals derived from an analogue conversion (12) of the stored digital tape parameters. The signal is then amplified (17) and passed to the read/write head for transfer to the tape. ADVANTAGE - Storing tape parameters obviates need to recalibrate videotape recorder for each successive videotape.

Title: Impregnating fabric with fluid e.g. resin for e.g. laminated PCB - by passing fabric into vacuum channel, for degassing, in the impregnating fluid, preventing bubbles
Inventor: GMEINER PAUL
IPC: B05C3/12
Filed: 1991-07-22
Abstract: To impregnate fabric workpieces (36) with a fluid, the fabric (36) is passed into a vacuum channel (20), with degassing, in the impregnating fluid. The underpressure within the vacuum channel (20) draws the fluid from the impregnation bath (28) into the channel (20) and holds it at a given level. The fabric (20) is finally drawn out of the vacuum channel (20) from the impregnating bath (20). The impregnating fluid within the vacuum channel (20) pref. flows against the direction of fabric (36) travel. The level of the impregnating fluid is held at a constant height in the vacuum channel (20) by continuous removal from the channel. ADVANTAGE - Partic. for impregnating a fabric with a resin, free of bubbles, to be pressed into a laminated layered material such as electronic circuit boards, the process gives a consistent impregnation.

Title: Impact absorbing tube section - has different cross=sections each side of weakening groove to provide telescopic action after shearing at groove
Inventor: TROMMER JOERG DIPL ING
IPC: B60R19/00
Filed: 1992-11-30
Abstract: The tube section is provided with a weakening groove (4) with the two edges of the groove having different bend angles. This ensures that the shearing action occurs at the bend with sharpest angle. After shearing the sections slide into each other.

The tube can be made of aluminium and has a reduced wall thickness at the groove. USE/ADVANTAGE - The impact absorbing tube is used for supporting vehicle bumpers, in steering columns or as part of the transmission. The shaping of the groove ensures that an even retarding force is obtained up to shearing, followed by the telescopic retarding force.
