Title: Arrangement for detecting the rotary position of a solid of revolution
Inventor: FRANK MANFRED DIPL ING
IPC: G01D5/14
Filed: 1993-03-10
Abstract: The invention relates to an arrangement for detecting the rotary position of a solid of revolution, which arrangement has at least two B field sensors (11, 12) which are offset spatially by 90 DEG relative to one another and are respectively arranged centrally between two magnets (7, 8) which are situated opposite one another with the same polarity and are spaced apart from one another, in which arrangement, furthermore, there are provided two soft magnetic sensor members (3, 4) which are driven by the solid (1) of revolution and which are arranged eccentrically in an opposing fashion with respect to a common axis of rotation and are spaced apart from one another axially in such a way that one sensor member (3) projects into the space between one magnet (7 and 9) and the B field sensors (11 and 12), and the other sensor member (4) projects into the space between the other magnet (8 and 10) and the B field sensors (11 and 12). <IMAGE>
Patent DE-4308503-A1 (DE)
Title: Switching controller, in particular for operation on loads having a capacitive component
Inventor: OHMS FRANZ DIPL ING
IPC: H02M1/00
Filed: 1993-03-18
Abstract: Switching controllers are often used as preliminary controllers (SR) for push-pull DC voltage transformers (GW) or other DC voltage transformers. The output-side capacitance (CA) of such a preliminary controller is usually selected to be large for reasons of stability. In the case of the invention, this output-side capacitance (CA) is reduced. In addition, for certain operating cases, for example the start-up phase of a push-pull DC voltage transformer connected downstream, the control gain of the switching controller (SR) is reduced. It is ensured by means of this measure that the system can react quickly to load changes without unstable behaviour occurring. <IMAGE>

Title: Differential refractometer esp. for liq. chromatography - operates in high sensitivity analysis mode and low sensitivity preparative mode
Inventor: KITAOKA MITSUO
IPC: G01N30/74
Filed: 1993-04-07
Abstract: (A) a differential refractometer has a flow cell divided into two cells by a partition inclined w.r.t.the optical axis of a measuring beam, sample soln. and reference soln. being passed through or held in respective cells. The measuring beam passes through a slit and then the flow cell and is reflected by a mirror back through the flow cell to produce a slit image on a photodetector. The novelty is that (i) the photodetector is subdvided into four sections by a first straight line, perpendicular to the slit image movement direction, and a second straight line, which is inclined w.r.t. the slit image movement direction and which intersects the first straight line; and (ii) an operational device receives output signals from the sections in order to derive the difference between sections flanking the first straight line, with the slit image lying transverse to the first straight line, for high sensitivity detection, while the difference between outputs of sections flanking the second straight line, with the slit image lying transverse to the second straight line, is derived for low sensitivity detection. (B) Also claimed is a liq. chromatograph including the above differential refractometer. ADVANTAGE - The differential refractometer can be used for high sensitivity applications, e.g. analysis, and for low sensitivity applications, e.g. preparative uses, without the need for flow cell replacement.

Title: Television tuner for terrestrial reception and satellite reception
Inventor: ARMBRUSTER VEIT DIPL ING
IPC: H04N5/44
Filed: 1993-06-03
Abstract: In terrestrial television reception, a conversion to a first IF and then a further conversion to a second IF are generally carried out. In satellite reception, a conversion takes place to a first IF, from which the baseband signal of the satellite signal is then obtained in an FM-PLL demodulator. Two separate tuners are generally used for this purpose. The object is to produce a common tuner for terrestrial reception and satellite reception which incurs minimum circuit cost. The second mixing stage (M2) is connected in terrestrial reception as a mixer for conversion to the second IF and in satellite reception as a component of an FM-PLL demodulator (30). Particularly for television receivers and video recorders for optional reception of a terrestrial antenna signal and a satellite antenna signal. <IMAGE>

Title: Method for using wind power by means of a jet-type wind turbine
Inventor: TEPE WALTER PROF DR
IPC: F03D1/06
Filed: 1993-07-10
Abstract: The jet-type wind turbine (JWT) uses the dynamic (total, Pitot, ram, stagnation) pressure of the wind by means of annular (ring) nozzles, which are arranged in a circular plane upstream of the rotor, in order to accelerate the incident wind and direct it at a constant angle onto the rotor blades. The annular (ring) nozzle plane + rotor with nacelle are mounted on a fork tower (mast) which is attached to a movable carriage by means of a rotating disc (swivel-head plate). In the event of a storm, the annular (ring) nozzle plane + rotor is tipped into a horizontal position. The efficiency of the JWT is 8-10 times higher than free-wheeling wind turbines.

Patent DE-4413132-A1 (DE)
Title: Method of determining leaks in a pipeline carrying gas or liquid
Inventor: ROSENTHAL FRANK DIPL ING
IPC: G01M3/24
Filed: 1994-04-19
Abstract: It is known to utilise data logging or analysis by means of classifying memories known from statistics in order to determine the presence of leaks. Here, digitalised individual measurements of variable measuring quantities are allocated to certain quantity classes. For the analysis, however, this known method requires a considerable computational input, which can only be implemented with computer programs which are expensive to design. By means of the invention, a method is to be provided which enables leaks to be determined quickly and in an energy-saving manner by means of the simplest computer programs. To this end, provision is made for a digitalised signal to be stored in a single memory in each case, the signals which correspond to a predetermined number of the lowest of all measured values being allocated to the single memories. By means of the invention, any leaks can be inferred directly from the stored values, which is possible with a very small computational input.
