Title: Process and device for determining the coordinates of a point on a surface
Inventor: TAUPIN PIERRE
IPC: G06K11/06
Filed: 1983-01-26
Granted: 1986-09-25
Abstract: A screen is disclosed on the surface of which a certain number of resistant conducting emitter strips and insulated conducting receiver strips are laid, the emitter strips being parallel-mounted with the terminals of a voltage generator and the receiver strips being interlaid between the receiver strips such that a conducting receiver strip lies between two resistant emitter strips. The electronics of control comprises an exploring stage to control the receiver strip time-related exploration. Thus, when a sufficiently conducting object used to indicate a point, has touched the surface and bridges an emitter strip and a receiver strip, a higher potential is detected on the corresponding receiver strip and the ordinate Y is given by the strip order number-while the abscissa X is calculated from measuring the potential between each ends of the emitter strip and the object.

Title: Magnetic head
Inventor: VISSER EELCO GERBEN
IPC: G11B5/245
Filed: 1983-01-26
Granted: 1987-12-17
Abstract: The head (1) has a (monocrystalline) core (2) of a magnetizable material which provides a substantially closed path for magnetic flux (B in write/read operations.

Granted: 1988-06-30
Abstract: In a motor-driven screw driving device, a drive unit and a drive member are located within a housing and are interconnected by a torque-limiting coupling. The coupling is adjustable by changing the force applied to a spring element. The spring element is supported within a stop sleeve located within the housing and the stop sleeve is axially displaceable relative to the housing. A depth stop on the drive spindle is adjustable relative to the stop sleeve. An actuating sleeve accessible on the exterior of the screw driving device affords the adjustment of the stop sleeve and the depth stop. A connecting element is secured to the actuating sleeve and is in engagement with the depth stop so that the actuating sleeve and depth stop can be rotated as a unit. The connecting element is selectively engageable with the stop sleeve so that the actuating sleeve and stop sleeve can be rotated as a unit for adjusting the torque-limiting coupling.

Abstract: Disclosed is a method for the operation of an electrostatic precipitator so as to provide a pure gas having a predetermined dust content with a minimum consumption of energy. Characteristics for the operation with an unpulsed voltage are recorded for different dust resistivities. Each characteristic has then associated with it that k value with which a pure gas having a predetermined dust can be achieved with a minimum energy consumption. During operation, the actual characteristic is compared with the recorded characteristics and that k value is selected which is associated with the recorded characteristic which coincides with the actual characteristic or is next below the actual characteristic. The actual characteristic is determined in predetermined intervals, the duration of which is determined in dependence on the speed with which the operating conditions may be expected to change.
