Title: Method and device for seismic signal acquisition in a bore hole
Inventor: DECORPS JEAN-LUC ROGER AUGUSTE
IPC: G01V1/40
Filed: 1983-07-12
Granted: 1987-11-19
Abstract: The present invention relates to the acquisition of seismic signals at different levels in a borehole, in response to the generation of seismic waves by a source placed on the surface or in the vicinity of the surface. The acquisition is carried out by means of a sonde suspended in the borehole from a cable and equipped with an anchoring pad. At each acquisition level, the pad is anchored in the borehole wall to couple the sonde to the formation, and then the pad is released from the wall once the acquisition is over. The signals acquired are then sent to the surface by means of the cable. The force with which the pad is anchored in the wall is controlled by means of a feedback arrangement which includes a sensor arranged in the pad itself. During the sonde movements from one level to another, the pad is kept in contact with the wall.

Abstract: Gas springs (5) are mounted between the sliding parts (2,3) of the two or more telescopic legs holding the mattress. These balance the weight of the support and that of the patient. The springs work independently to allow an infinite number of height and tilt positions. A lock screw (4) for the springs allows setting at a particular height. A calibrating piston (10) for each gas spring allows counterbalancing to suit different patients. The release mechanisms for the gas spring locks are pref. joined to act simultaneously.

One side of the bar of the sheet-holder member has a rib (8) which may engage in the base member (1) in one of the parallel grooves (4) therein. The lateral spacing of the parallel grooves (4) and the vertical spacing of line of letters on the dry transfer sheet (22) correspond to ensure accurate horizontal alignment of letters transferred from different rows on the transfer sheet to the final receptor. Convenient transfer sheet layouts are described.

Patent DE-3583915-D1 (DE)
Inventor: BRAEUNINGER JUERGEN DR RER NAT
IPC: B60T8/66
Filed: 1985-09-21
Granted: 1991-10-02
Abstract: The control circuit uses a microprocessor system and evaluates the appropriate speed reference for the vehicle. Speed sensors or transducers on each axle send information to their respective anti-blocking regulator processors. One of the processors is programmed to evaluate the instantaneous speed reference which is then passed to the other regulator processors for action including its own. For fast action the signals are passed in a series loop using code numbers. The code numbers relate to the references which the individual processors have determined, and they are offered to the evaluating processor. This selects the highest priority code, for example one with a positive slope (i.e. higher than the existing reference) and sends this out as the new reference. All regulators act on the new reference and control their brake valves, accordingly.

Abstract: The Parent Patent suggested the addn. of a rubber-diaphragm non-return valve in the discharge pipe which is kept closed by a water column until the pumping cycle begins. After longer waiting periods there is a risk of this column seeping away so that the purpose of the valve (not to waste washing agents) is not achieved. This can now be overcome by briefly turning on the suds pump to replenish the water column, before every program starts and before fresh water and washing agents reach the suds tank.
