Patent DE-3000288-A1 (DE)
Title: Position adjustment of rotating video head - using piezoelectric device with contactless signal transfer between stationary and rotating parts
Inventor: ZOELLNER RAINER
IPC: H02N2/06
Filed: 1980-01-05
Abstract: The design of video head eliminates the need for high accuracy and reliability rotating contact arrangements to feed adjusting signals to a piezoelectric device (18) for setting a video head (10) on a rotating disc (20). In the space between the stationary part (19) of the equipment and the spindle (9) driving the plate (20) on which the video heads (10) are mounted are the electrodes of capacitors (13). One electrode is attached to the bore of the stationary part and the other to the outer surface of the spindle. The electrodes thus form concentric rings. The amplitude modulated voltage output of a resonant circuit in the position control loop is applied to the stationary electrode and, by capacitor coupling, is transferred to the rotating electrode. Here the output is rectified (14,15) and applied to the piezoelectric adjusting device circuit (17,18). The resulting d.c. level, which may be smoothed (16), acting on the piezoelectric device sets the position of the video head (10).

Title: Moisture-absorbing layer in vehicle air filter - is sepd. from gas-absorbing layers by regenerating heater
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D53/86
Filed: 1980-01-16
Abstract: The layers of chemisorbtive and catalytic material in a filter for supplying purified air to a vehicle interior are sepd. from a dryin filter layer by a heater supplied from the vehicle's electrical system. This ensures that only a small quantity of very hot air is utilised to expel the collected moisture which is expelled by a fan into the atmos. Appreciably less regenerated air the fresh air is used to ventilate the interior. During regeneration sec. air is entrained with the hot prim. air, and the resulting lower temp. protects the fan. Primarily for use in congested traffic, when both noxious gases and moisture are adsorbed. During subsequent less contaminated travel the filter is regenerated. The appts. only heats the moisture-adsorbing layer, so reducing power consumption, while the other layers are regenerated by cooler air.

Abstract: A device for room ventilation in walls or floors of buildings comprises, for simultaneously fulfilling the requirements for satisfactory ventilation and sound insulation and protection against fire, one or more structural parts consisting of ceramic foam material. The ducts used for channelling air are worked into the foam material such that they run directly one beside the other. The inner duct surfaces are thus formed from vertical drops in the foam material of the structural parts. Through-passages worked into the foam material open, as connection ducts, into the abovementioned ducts. Over the entire extent of the ducts, the latter are provided with cross-sectional constrictions, arranged at predetermined intervals, in order to achieve an increased sound insulation. Furthermore, between these cross-sectional constrictions in each duct, for protection against fire a closure element on an actuating element, by means of which the duct cross-section is closed off in the event of a fire, can move between successive cross-sectional constrictions. <IMAGE>

Title: Method and device for determining the consistency of mixed concrete
Inventor: BROCKMANN GUENTER ING GRAD
IPC: G01N33/38
Filed: 1981-04-04
Abstract: The invention proceeds from a method for determining the consistency of mixed concrete, in particular in a mixer lorry (mixer conveyor, mixer truck). A test stirrer driven at constant speed is introduced into the mixed concrete and the test stirrer power is used as a measure of its consistency. The power is not measured, however, on the basis of the current consumption of the drive motor of the test stirrer but, on the contrary, a flow of concrete is generated with the test stirrer and guided towards or onto a test backing surface. The test backing surface deforms and its deformation is used as a measure of the consistency of the concrete. The invention also relates to devices for carrying out such a method. These have a test stirrer and a test backing surface, and the test backing surface may act as impact backing surface for the flow of concrete or as a support for a concrete cake formed therefrom. <IMAGE>

Title: Bath/shower battery
Inventor: ZWINK HELMUT
IPC: F16K11/044
Filed: 1981-06-20
Abstract: In a bath/shower battery, the semi-automatic changeover between the shower and the bath tub is also used to convert the plug hole into a ventilation path to eliminate the risk that dirty water will be sucked back into the household piping via the hose of the shower attachment if a vacuum occurs in the household piping to which the battery is connected. To ensure that enough air can be drawn in via the plug hole in all operating states (the plug hole is generally covered by a perforated plate for the entry of air), a pipe ventilator known per se is inserted as a precaution between the shower/bath tub changeover device and the perforated plate. This makes it possible to guarantee a reliable back suction safeguard for the hose of the shower attachment under geometrically favourable conditions. In particular, it allows the said hose to be routed downwards from the battery without conflicting with the wall of the bath tub.
