Patent DE-3338436-A1 (DE)
Title: Short-time NMR tomograph system
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: G01R33/20
Filed: 1983-10-22
Abstract: A novel NMR diagnostic tomographic system for human in vivo diagnosis with two-rail evaluation and low radiation risk employs 20-30 kW X-ray radiation with a 10 to 300 megahertz VHF signal superimposed. The carrier and superimposed signal are emitted as a soft X-ray beam pulsed at about 50 hertz by a small incandescent-cathode X-ray tube, which beam can be directed at the protein of the subject. The analysis opens up the possibility that, because of the special nature of the system, not only the proton spin of the hydrogen atoms, but the spins of carbon, nitrogen, phosphorus etc. can be used in deciphering the chemical shifts whose pathological effects are being sought. The high sensitivity and, consequently, the short-time photogrammetry are due to the fact that the X-ray carrier, on the one hand, intensifies the VHF excitation by a factor of up to 10<8> and [lacuna] finds, on the other hand, in the two-rail type of evaluation of the X-ray carrier radiation evaluation also by the Mössbauer absorption principle. Taken together, the VHF effect and the Mössbauer effect with X-ray quanta instead of gamma quanta open up the possibility of extended decipherment information, an expanded spin spectrum using C, N and P, and shorter exposure time with reduced radiation risk. In some cases, the two-rail system also renders the stationary magnetic field unnecessary.

Patent DE-3404319-A1 (DE)
Title: Fishing device
Inventor: KOZIKOWSKI TOMASZ
IPC: A01K91/02
Filed: 1984-02-08
Abstract: The fishing device uses, in order to cast a bait attached to a line, a miniature water vehicle (4). The bait is received by a holder, by means of a partial section of a line which can be stored on a reel, the holder being arranged on the miniature water vehicle (4). The holder preferably consists of a container (5), having an aperture (6) which points upwards or downwards as a function of the position of rotation of the container (5). The container (5) can be locked in a position of rotation, the aperture (6) pointing upwards. If the locking is cancelled, a rotary movement of 180 DEG  takes place about the axis of rotation of the container (5), caused by the force of a pre-stressed torsion spring (9), so that the aperture (6) thereupon points downwards. In this position of the container (5), the partial section of the line with the bait is exposed. The miniature water vehicle (4) and the unlocking of the container (5) can be remote-controlled via devices known per se. <IMAGE>
Patent DE-3405534-A1 (DE)
Title: Optical receiver
Inventor: SCHROEDER HELMUT DIPL ING
IPC: H04B10/69
Filed: 1984-02-16
Abstract: The described optical receiver contains a reverse-biased photodiode whose one electrode is connected via a coupling capacitor to an input terminal of a transimpedance amplifier and a resistance circuit which is connected in series with the photodiode and whose resistance value is dependent on the photocurrent. The resistance circuit essentially comprises two transistors, with the aid of which the dynamic range of the optical receiver is extended in such a way that even the unattenuated transmission power of a laser is converted free of distortion into electric signals. Due to the DC component of the photocurrent, the collector-emitter paths of the transistors are conductively controlled and in this way an AC resistor is connected in parallel with the input resistor of the transimpedance amplifier. The AC input current of the transimpedance amplifier is limited in such a way that overload is prevented.
Patent DE-3405886-A1 (DE)
Title: Method and device for the polarimetric measurement of the rolling angle of a movable machine part
Inventor: SCHUESSLER HANS-H DIPL ING DR
IPC: G01B11/26
Filed: 1984-02-18
Abstract: The invention relates to a method for the polarimetric measurement of the rolling angle of a movable machine part. In order to increase the accuracy of resolution of the rolling angle in polarimetric measurement, two components of linearly polarised light are isolated from the light, which have directions of polarisation that are at least approximately mutually perpendicular and which in terms of angle adopt - in the neutral position of the machine part with regard to the rolling movement - a relative position of 45 DEG  between the measuring direction and reference direction. Given a change in the rolling state with respect to the neutral position, one light component increases, whereas the other light component decreases, so that the difference between these two light components can be used as a measure of the rolling angle. Various devices for realising this method are described. The method can, furthermore, also be applied for the purpose of refining measurement of the light-turning effect of light-transmitting substances.

Title: Propulsion charge for large-calibre weapons
Inventor: SCHLEICHER ULRICH DR
IPC: F42B5/38
Filed: 1984-05-12
Abstract: Propulsion charges for large-calibre weapons may have a relatively large detonation separation from the detonating cartridge, with a short shot width in the lodging space of the weapon. As detonation separation becomes larger, the ignition capability of the ignition elements which are arranged in or on the propulsion charge reduces. A propulsion charge which is constructed as a module has all the environmentally sensitive ignition elements (15, 16-19) and charge components (6) inside a cartridge container (3). The ignition capability of the propulsion charge (6) over relatively long distances is ensured by means of a pyrotechnic layer (15) which is arranged in a high-pressure space (11) in the cartridge container (3). The high-pressure space (11) causes the intensive ignition of the propulsion charge (6) over a large area. This additionally ensures that a module (30) arranged downstream is reliably detonated.   <IMAGE>

Title: Serial tetrad adder/subtractor in excess-3 code with decimal inputs and decimal outputs
IPC: G06F7/50
Filed: 1984-07-06
Abstract: This tetrad adder/subtractor has as the main circuit a dual tetrad subtractor 1 which processes excess-3-coded decimal numbers. This adder/subtractor thus has two input code conversion circuits 5 and 6 which convert decimal-1-of-10-coded decimal numbers into excess-3-coded decimal numbers and an output code conversion circuit 9 which converts BCD-8421-coded decimal numbers into decimal-1-of-10-coded decimal numbers. The advantage according to the invention is that a very simple correction circuit 2 can be used which only consists of 3 dual half subtractors and a residual circuit 27. The subtractions are thus carried out in a normal manner and the additions are carried out by means of subtractive addition. During the subtraction, the B inputs are the minuend inputs and the A inputs are the subtrahend inputs. The drive potential for the carry input n is supplied by the circuit 8. <IMAGE>
