Patent DE-3243258-A1 (DE)
Title: Measuring instrument
Inventor: BAIER PAUL WALTER PROF DR ING
IPC: G01R21/08
Filed: 1982-11-23
Abstract: In a measuring instrument (1) for determining the power and the energy consumption of a consumer (3) of electrical energy, a measurement-value pickup (11) exhibiting a Hall generator is inserted into its circuit, the output voltage of which, formed as the product of voltage and current, is supplied as control voltage to a voltage-controlled oscillator (14). Furthermore, a computing unit (16) for evaluating the output frequency is connected to the voltage-controlled oscillator (14). This makes it possible to determine at the same time the instantaneous power consumption and the energy consumption of the consumer (3) by simple means and without requiring switching. <IMAGE>

Title: Method for measuring the optical length of a light path, and laser interferometer for carrying out this method
Inventor: KULES VLADIMIR PETROVIC
IPC: G01J9/04
Filed: 1983-02-25
Abstract: The method for measuring an optical path length is based on exploiting the multiple-beam interference of the light, and is carried out by generating an output light bundle having two colinear components which have mutually independent polarisations and different frequencies, it being the case that during the formation of each subsequent interfering light bundle from the preceding light bundle the polarisations having different frequencies are converted mutually into one another, after which the interfered light is converted into an electrical signal and the phase of the electrical signal is measured. The laser interferometer contains a laser (4) and reflecting elements (1) and (2) arranged sequentially in the direction of the light beam, a polarisation element (11) for splitting the light of the interfering bundles depending on polarisation, and a photoelectric transducer (9) for converting the interfered light into an electrical signal, as well as a unit (10) for measuring the phase of the electrical signal, which is connected to the photoelectric transducer (9). The interferometer also contains a birefringent plate (3) which is arranged between the elements (1) and (2) and serves the purpose of mutual conversion of the polarisations of the two light components. <IMAGE>

Title: Closed implement combination for agriculture
Inventor: HIGGEN REINHARD
IPC: A01B71/06
Filed: 1983-09-06
Abstract: Closed implement combination for agriculture, consisting of a ground-working implement arranged especially on the three-point power lift of a tractor and connected to the tractor take-off shaft by means of a cardan shaft, and of a tilling machine which is connected to the ground-working implement via coupling parts designed as lifting frames and which can be raised by means of the lifting frame, the tilling machine being driveable from the tractor take-off shaft via a cardan shaft arranged between the driven output shaft of the ground-working implement and the tilling machine, and stops limiting the lifting range of the lifting frame during the use of the implement combination, in such a way that the maximum permissible angling of the cardan shaft is not exceeded, so that the tilling machine can be driven uninterruptedly even while it is in its lifted-out state. In order to improve the known lift-out limitation for the sowing machine via the lifting frame, a releasable hydraulic stop valve (22) is arranged in the delivery line (9) leading to the lifting cylinder (8), this hydraulic stop valve (22) cooperating with the stops (28). <IMAGE>

Title: Process and apparatus for separating solid suspensions and liquids, in particular coal flotation slurries
Inventor: HARTMANN HEINZ LEOPOLD
IPC: B01D21/28
Filed: 1984-03-14
Abstract: The aim of the invention is to make the known processing stages of coal flotation slurries from the preclarification tank to the dredging of the slurry pond unnecessary, in order to achieve cost savings in this manner. This is achieved by introducing the two-phase mixture into a vessel, by vibrating the vessel at intervals by means of a three-point bearing which can be set into mechanical oscillations, each of which bearings has a hydraulic pressure cylinder device which is driven by an electrical rotary generator having changeable amplitude shapes and continuously changeable frequencies and by separate discharge of the mixing components separated over each other, first by allowing the liquid components to drain off by opening side ports and then by emptying out the solid components by tipping the vessel.

Patent DE-3422746-A1 (DE)
Title: Insulating system for layer windings
Inventor: KIENREICH WALTER ING
IPC: H01F27/32
Filed: 1984-06-19
Abstract: The current-carrying conductors of the windings or else the individual winding layers have to be insulated from one another for reasons of dielectric strength. Similarly, the coils are subjected to great mechanical forces, which often can only be controlled by very expensive measures. The object of the invention is to provide an insulating system which forms a compact block of windings clamped together in every direction and ensures complete impregnation with insulating liquid. In the insulating arrangement for layer windings in the case of coils of liquid-cooled transformers and inductors, in which the electric conductors (1) of square or rectangular cross-section are arranged with insulating tapes (2), the insulating tapes (2) have a heat-activatable adhesive layer. For impregnating the coil with insulating oil, the electric conductors (1) of the layer winding are in each case wrapped with insulating tape (2), on which adhesive resin spots (2) are printed, as a multi-layered insulating covering applied transversely to the conductor winding. <IMAGE>

Title: Process for reducing copper melts
Inventor: TRAPPMANN WOLFGANG DIPL ING
IPC: C22B15/00
Filed: 1984-11-29
Abstract: The poling of copper melts by dipping tree trunks into the melt is a very old process step in the fire-refining of copper melts. This method is very involved but until now has proved economically superior to any attempted replacement methods, especially using hydrocarbons. In order to carry out the poling of copper melts (3) less laboriously and expensively, it is proposed to pass methanol as the carbon-containing substance into the melt. Methanol in this process is thermally dissociated into CO and H2. If methanol is introduced as a liquid, the substantial increase in volume generates vigorous bath turbulence. The bath turbulence can be increased further by simultaneous addition of an inert gas, for example nitrogen.

Title: Method and device for controlling the air intake flow of an internal combustion engine as a function of the output torque
Inventor: HOSAKA AKIO
IPC: F02D41/14
Filed: 1985-02-07
Abstract: The invention relates to a method and a device for controlling the air intake flow of an internal combustion engine, in which the angular position of a throttle valve is controlled by electrical means. The device comprises an accelerator pedal, which generates a signal representative of the required or necessary output torque. The actual output torque is monitored by means of a torque sensor. The actual torque is compared with the torque demand determined on the basis of the signal from the accelerator pedal. From the difference calculated between the actual torque and the torque demand, a feedback control of the angular position of the throttle valve is performed.
