Title: Proximity detector power supply - combined constant current and low impedance power supply circuit
Inventor: ZWICKER WOLFGANG DIPL ING
IPC: H03K17/95
Filed: 1991-01-19
Abstract: The proximity detector (3) is supplied with current by two parallel circuits, a constant current circuit (T1,R1,R2,Z2) and a low impedance circuit (T3,R3,R4,L). When the detector output is low, current is supplied to the detector via the constant current circuit components T1 and R2. The detector output transistor (T2) ensures that the base voltage of the low impedance circuit transistor (T3) (applied via R4) remains high. When the low impedance circuit transistor (T3) goes high, the detector output transistor (T2) turns on the low impedance circuit transistor (T3) via an LED (L) thus providing current to the detector. The LED also provides a visual indication of the change of state of the detector. A diode (D) guards against inadvertent reversal of the supply polarity, a Zener diode (Z1) protects against excessive voltage overload, while a capacitor (C) prevents spurous HF signals from reaching the detector. ADVANTAGE - Alleviates problems caused by high input impedance of proximity detector.

Patent DE-4135904-A1 (DE)
Inventor: KAHRS MANFRED DR
IPC: F04B1/04
Filed: 1991-10-31
Abstract: The invention relates to a piston pump with suction regulation, especially for motor vehicles, and preferably with a control stub for internal admission. It is the purpose of the invention to provide such a pump with a constant supply flow rate over a wide revolution speed range and the lowest possible losses and low noise level. To this end the present invention proposes several solutions. In a first, the control slot (13) on the pressure side is divided into several grooves (27, 28), which are at least partly connected to the pressure link (20) via non-return valves (32). In another, the shape of the control slot on the pressure side is adapted to the optimum operating mode by making its inlet end relatively narrow to reduce the noise level (noise reduction at high revolution speeds) and keeping an adequate width at the outlet end for the power required. In a third, the arrangement for the slot (12) on the intake side is similar to that of the second solution and its length also affects the degree of filling of the piston drilling.

Title: Detecting and classifying sound waves esp. of vehicles using geophones e.g. for mine detection
Inventor: BECKER GUNNAR
IPC: G01V1/00
Filed: 1992-04-10
Abstract: The method uses geophones applied to the ground for the reception of ground sound waves . The wave-type detected (P- or Rayleigh-wave) is determined by the ground sound wave received using the geophones (11, 12) and is also called up as a further parameter with the adaption of the reference level (Pref). The ground sound waves determine a graph, for the dependence of the geophone output level relative to a geophone related speed, from the seismic propagation speed of the ground sound waves, for the significant types of wave. The graph is stored as a seismic propagation model with which the measured seismic propagation speed and the wave type are determined from the allocated propagation model. A corresponding adaption level (Padapt) is removed and is corrected with the reference level.
