Title: Propulsion means with two motors driven in an opposite direction for the compensation of the backlashes
Inventor: SUTER HANS-JORG
IPC: H02P5/685
Filed: 1982-05-12
Granted: 1986-01-30
Abstract: With small drive torque the motors counteract one another, with full-load output they act in the same sense upon the load, so that the backlash or play between the drive, the gearing and the load is eliminated. As the motors there are used compound motors whose armatures and shunt windings are connected in series. The series excitation currents are controlled by means of two 2-quadrant power adjustment or setting elements and the external excitation current is controlled by a 2-quadrant adjustment or setting element of small output.

Title: Connecting terminal for electrical conductors
Inventor: STENZ PAUL
IPC: H01R4/38
Filed: 1982-11-06
Granted: 1987-10-08
Abstract: A connector for clamping one or more electrical conductors has a shackle which cooperates with a screw serving to urge one end portion of a rail toward a bottom wall of the shackle. The bottom wall has a central portion flanked by two convergent lateral portions which guide one or more conductors against the internal surface of the central portion when the screw causes the end portion of the rail to approach the bottom wall. The underside of the end portion of the rail has a centrally located platform whose underside urges the conductor or conductors against the central portion of the bottom wall and which is assisted by two ridges disposed between pairs of recesses in the end portion of the rail. The lateral portions of the bottom wall have notches which receive portions of the platform, and the recesses receive portions of the corresponding lateral wall portions. The undersides of the ridges can constitute concave surfaces to further enhance the gathering, centering and clamping effect of the end portion of the rail when the screw is rotated in a direction to advance the end portion toward the inner side of the bottom wall.

Abstract: An apparatus for detecting the concentration of certain analytes, including hydrocarbons, in a liquid medium, is disclosed. The apparatus uses a planar or "open" capacitor containing an active layer. In response to selected analyte in the liquid medium, the active layer causes capacitance to decrease with increasing analyte concentration. The capacitance decreases because higher dielectric water molecules are displaced from a region of the capacitor's electric field. For certain hydrocarbon analytes having high Henry's Law constants, the active layer causes bubbles to nucleate in the liquid medium on the surface of the active layer. Bubble formation displaces water molecules and decreases capacitance.
