Title: Electric power measuring appts. - has converters for voltage dependent values into signal trains of different frequencies and has signal duration detectors
Inventor: ZIEHER PETER ING GRAD
IPC: G01R21/133
Filed: 1979-05-16
Abstract: The appts. may be in the form of a Watt-hour meter in which both the voltage and current values are converted into signal trains of different frequencies in order to attain a higher precision. These frequencies are mutually multiplied by counting the higher frequency signals during a time-limited signal period of the lower frequency. The counting takes place via a frequency reduction stage (19) in a counter (20). Pref. the two signal trains are interconnected via an AND-gate (18). The signal period duration may be determined by timing elements (15, 17). The meter is pref. used for limiting the cost of electric consuming appliances, such as battery driven vehicles, in which both the current and the volt. are fluctuating. It enables a highly precise determination of power consumption by digital techniques.

Title: Coordinate dimension measuring device with simplified measuring head - using transducers in perpendicular planes to monitor probe carrier position
Inventor: HUEBNER GERD DIPL ING
IPC: G01B7/012
Filed: 1979-09-21
Abstract: The dimension measuring device uses a measuring head, which can be moved by a measured amount in several co-ordinate directions. It comprises a housing with a probe carrier, from which at least one probe arm extends, the probe carrier mounted within the housing for relative linear and rotational movement in a max of six free senses of a spatial coordinate system. This relative movement of the probe carrier is detected by six transducers, arranged in pairs in three mutually perpendicular planes. The transducers are coupled via a common amplifier and an a-d converter to a calculator, which obtains the position of the probe from that of the probe carrier relative to the housing. The constructional and technical complexity of the measuring head is reduced, with the probe carrier being unaffected by guidance errors.

The siphon tubes lead into an upper annular drainage channel in the superstructure and the amt. of material which can be handled by the siphon tubes is controllable. This is dependent on the amt. of sludge on the respective parts of the bottom of the settling tank or on the associated operating capacity. Pref. control is dependent on the movement of the gantry and siphon tubes in different parts of the tank are controlled independently.

Title: Automatic path control of road vehicle - has sensors in vehicle reacting to signal in conductor set into road surface
Inventor: RUBEL ERICH DIPL ING
IPC: G05D1/02
Filed: 1979-11-17
Abstract: Automatic path control of a railless vehicle uses a sensor system that detects the field generated by a signal carrying conductor inset into the road surface. Two coils are located at a fixed height in the vehicle, one set horizontally and one set vertically. If the vehicle is positioned off centre from the conductor, each coil generates an a.c. signal proportional to the angle subtended relative to the vertical and the conductor. The signals from each coil (13, 14) are amplified (20, 23) and are processed by two comparators (21, 22). The comparator outputs are generated in the form of rectangular pulse trains, derived from the a.c. signals. There is a phase difference between the two signals (c, d) that is proportional to the angle caused by the off centre position of the vehicle. A microprocessor interprets the phase difference to control the vehicle steering.

Title: Integrated MOS electronic component - has V=shaped grooves arranged next to bit conductive diffusion region, using additional etch-selective layer
Inventor: EDWARDS DAVID DR
IPC: H01L21/336
Filed: 1980-07-28
Abstract: The V-shaped grooves of the highly integrated MOS components are arranged adjacent to the diffusion region, serving as a bit line, using an additional etch,selective layer. They form with this region at least one transistor. The additional layer pref. consists of a silicon nitride. This layer is deposited on the diffusion layer after thermal oxidation. After a selective etching it serves for structuring of the diffusion layer. The nitride layer is selectively etched away after etching the V-shaped holes. The nitride layer (5) is pref. deposited on the substrate (8) prior to depositing of the diffusion layer (3). The second selective etching of the nitride layer provides structuring of the V-MOS regions (11). After a local thermal oxidation of the uncovered silicon region, the remaining nitride layer is removed by third etching step. A highly integrated memory is produced with reduced capacitive coupling between word and bit lines.

Title: Apparatus for applying viscous material, in particular epoxy resin, to receiving surfaces of workpieces
Inventor: HEIM RICHARD
IPC: B05C5/02
Filed: 1981-02-06
Abstract: An apparatus (1) for applying viscous material, in particular epoxy resin, or mixtures containing epoxy resin, to receiving surfaces of workpieces (2) has a substantially vertically arranged container (6) for the material. The end face (12) of the container (6), facing the workpiece (2) contains one or more outlet openings (13) for the material. A raising and lowering mechanism (14) serves to lower the container (6) in order that the end face (12) can be set down on the receiving surface of the workpiece (2), and subsequently to lift the container (6) off again from the workpiece (2). The height of each outlet opening (13) is less than its average cross-sectional dimension and, in the case of very different cross-sectional dimensions, is preferably at most equal to the smallest cross-sectional dimension. This dimensioning of the outlet openings together with the viscosity of the material achieves the effect that the material is discharged from the container without the aid of plungers, doctor blades or other mechanical parts and is applied to the receiving surfaces of the workpieces. <IMAGE>
