Title: Moving target classification using Doppler radar - standardising video signals from echo signals and frequency values of give Doppler frequency
Inventor: FEDERSPIELER PHILIPP DR ING
IPC: G01S7/41
Filed: 1980-01-22
Abstract: The target classification process uses a Doppler radar with state sign suppression. The echo signals of moving targets are investigated by spectral analysis for periodical secondary lines of the Doppler frequency spectrum, the lines being generated by periodical changes in the reflection conditions of the target, or by parts of the target. The secondary lines, characteristic for the target classifications are eliminated and evaluated, as in Patent No. 2928907. The video signals, derived from the echo signals, or the frequency values obtained from the spectral analysis, are standardised by shifting the entire frequency spectrum to the Doppler frequency in such manner as to obtain a zero Hz value for the Doppler frequency line. The standardisation with analog evaluation of the video signals takes place by mixing the latter with the Doppler frequency. In digital evaluation the video signals may be scanned by the Doppler frequency.

Title: Enzyme modulator-ligand complexes - e.g. pepstatin-thyroxine ethyl ester complexes, and their use in enzyme mediated assay of ligands in body fluids
Inventor: THOMA HANS A DIPL CHEM DR
IPC: C12N9/96
Filed: 1980-02-22
Abstract: New enzyme modulator/ligand conjugates comprise an enzyme modulator component capable of irreversibly influencing and/or covalently binding the reference enzyme. New procedure for the determination of a ligand (esp. a biologically active cpd.) comprises (a) introducing into a liquid medium in a suitable order the (serum) specimen, the above enzyme modulator/ligand conjugate, a receptor which reacts under the influence of the enzyme modulator component, the reference enzyme and a substrate for the reference enzyme, (b) ccarrying out the reaction homogeneously or heterogeneously and (c) measuring the activity of the reference enzume. Measurement of substances such as pharmaceuticals, drugs, narcotics hormones, steroids, polypeptides, prostaglandins, toxins, etc. in body fluids such as blood or urine, e.g. in medical diagnosis. The use of enzyme modulator/ligand complexes in the determination is based on the finding that the irreversible effect of the enzyme modulator on the reference enzyme can be locked by the presence of receptors (esp. antibodies) for the ligand to which the enzymes modulator is bound. The new method is suitable for the determination of ligand concns. in the picomole range.

Title: Welding of pipes of hollow ware in protective gas atmos - where two inflatable bags form gas seals inside pipes and also feed gas to nozzle filling pipe ends with gas
Inventor: SCHOENWAELDER JOACHIM
IPC: B23K9/028
Filed: 1980-03-04
Abstract: Each workpiece, esp. two pipes (1,2) being butt welded, is sealed in its bore with an inflatable bag or balloon (3,4). The two bags are joined to each other via two hose couplings and a gas outlet nozzle (5). Both bags (3,4) are inflated by an inert or protective gas, so nozzle (5) occupies a posn. in the middle of the welding zone inside the two pipes (1,2). Only one gas supply pipe is used to supply one of the bags (3,4), because the gas flows via nozzle (5) into the other bag while also flowing into the ends of both pipes (1,2). The advantage is that one pair of bags (3,4) can be used for pipes of different dia.

Title: Standard of length for checking the accuracy of measurement of measuring instruments
Inventor: SCHUESSLER HANS-HEINRICH DIPL
IPC: G01B5/00
Filed: 1981-08-17
Abstract: The invention relates to a standard of length for checking the accuracy of measurement of measuring instruments, in which scannable measuring surfaces are arranged at a known spacing. In order to exclude temperature-induced changes in the length, the measuring surfaces are provided on a carriage which can be displaced on a guide rail and locked thereon at different positions. The measuring surfaces in this case assume their spaced positions sequentially in time. In order to determine the exact spacing of the positions which are assumed sequentially, there is mounted on the guide rail an interferometer arrangement which consists of a fixed interferometer divider with a triple reflector for the reference beam, and of a reflector on the carriage. It is likewise possible to provide on the opposite side from the interferometer divider scannable surfaces which for their part are supported by a fixed body, or likewise by a carriage. The standard of length cannot only be used to set spacings of the measuring surfaces to the finest gradation - it is also possible to simulate rows of balls or rows of bores with very fine spacing gradation.
