Patent DE-4003050-A1 (DE)
Inventor: RUMLAND RAINER DIPL ING
IPC: H04N7/18
Filed: 1990-02-02
Abstract: It is normal in video monitoring devices for a relatively large number of monitoring cameras and a smaller number of monitors to be provided. The monitoring cameras are then switched alternately through to the monitors with a video matrix. Since the transmission lines cause distortions, equalizing amplifiers are fitted in front of the video matrix in order to compensate for the distortions. For this purpose, one equalizing amplifier is required for each transmission line. The object of the invention is to reduce the number of equalizing amplifiers required. This reduction can be achieved by disposing the equalizing amplifiers after the video matrix and by extracting the required equalization values from a memory dependent on the selected input and by feeding them to the equalizer as correction values. Through this arrangement, the number of equalizing amplifiers required is equal only to the number of outputs present on the video matrix. <IMAGE>

Title: Roll=up curtain mechanism - has locking pin working in different guides for winding and unwinding
Inventor: MALMSTROEM SVEN ERIK
IPC: E06B9/90
Filed: 1990-02-22
Abstract: The roll-up curtain mechanism comprises stationary (14) and rotary (12) members working together.  The latter is fixed to a bar (11) onto which the curtain winds, and has a torsion spring (16) acting in the winding direction.  A locking mechanism secures member and bar with the curtain unwound to the desired degree, and is released by tugging on the curtain. The locking mechanism comprises a pin (18) on one of the members, working with a locking device (23) and a guide (20-22) on the other. One section (19) allows free relative movement of the pin when unwinding, and another (20) does so when winding, the sections being spaced apart.  When the pin is in the first section and the curtain moves in the winding direction, it engages with the locking device (23), which is situated between the sections, preventing winding.  On unwinding, the pin moves into the second section. USE/ADVANTAGE - Low noise level and no locking catches on roll-up curtain mechanism.

Title: Drum washing machine with drum drive motor - in which rotor is coupled to tachogenerator
Inventor: HILDEBRAND BERND DIPL ING
IPC: D06F33/30
Filed: 1990-11-28
Abstract: A drum washing machine incorporates a drum, the drive shaft of which is connected to a position indicator that works in a contact-free manner. The rotor of the drive motor of the drum is coupled to a tacho-alternator torsion-resistantly.

Title: Controlling drink dispense from pressurised container - by adjusting feed pressure against internal counter pressure
Inventor: METTE MANFRED DR ING
IPC: B01F15/04
Filed: 1990-12-06
Abstract: Liq. (3) held in a container (1) under the pressure in the upper part of the enclosed container of gas (4) supplied from an internal feeder (8) is delivered into an axial metering chamber (2) by the gas pressure, via an aperture (27) normally closed by an annular seal (26).  The vol. of liq. received in the metering chamber is determined by the balance between the supply pressure and that in an upper counter-pressure chamber, and can be varied as desired.  The upper chamber occupies an inverted bell structure (24), closed at its head. A rotary valve (9) at the metering chamber foot (9) is opened to deliver the metered vol. into one of a succession of moving containers (12), or into admixture with one or more  further components. USE/ADVANTAGE - For drink or mixed drink dispensing.  Metering accuracy is largely independent of storage container pressure. Absence of moving seals improves reliability and facilitates cleaning.
