Patent DE-4130628-A1 (DE)
Title: Optimising use of dynamic range of  photodiode array in spectrometer with pulsed lamps - using successive flashes with different energy levels, and additively correcting combination of unsaturated spectral regions
Inventor: RINKE GUENTER DR
IPC: G01J3/28
Filed: 1991-09-14
Abstract: The method for the optimal use of the dynamic range of a photodiode array and for evaluating the array signal involves using a flash lamp as a light source with two different energy levels in successive flashes. During the weaker and stronger flashes, the most and least intensive spectral regions are evaluated respectively. The different energy levels are produced by applying corresp. adjusted charge voltages to the mains stage of the lamp so that the spectral region to be evaluated is not saturated. The unsaturated regions with different flash energy are combined additively using correction factors. ADVANTAGE - For measuring intensity distribution of light incident on photodiode array.

Title: Packing material made of waste paper - comprises press moulded waste paper-water dough giving thin walled, lightweight package which tapers to the opening, making stacking impossible
Inventor: VONRHEIN GERHARD
IPC: B65D81/09
Filed: 1991-10-24
Abstract: Hollow bodies used as packing are new and are produced from waste paper which is e.g. ground and mixed with water to give a dough which is pressed in a mould without using a binder and allowed to dry. The hollow bodies are thin walled and taper to their openings so that they cannot be stacked one inside another. Compared to conventional packing materials such as foamed polystyrene chips, wood wool, paper wool etc., the material has an extremely high air content. ADVANTAGE - The material is inexpensive uses recycled waste paper, requires no binder, is light and saves transport costs.
Patent DE-4136091-A1 (DE)
Title: Synchronising code words of cyclic, non-binary, corrected code - dividing symbol sequence to be decoded into code words with determined number of symbols
Inventor: ENGEL ANDREAS DIPL ING
IPC: H03M13/33
Filed: 1991-11-02
Abstract: The symbol sequence to be decoded is divided into code words, consisting of a number of successive symbols, determd. by the used code. For each code word, or some of them, a fault pattern is determd. in which a number value represents faulty code word symbols, while another number value represents fault-free symbols. Each fault pattern is linked to a reference pattern of a series of preset such patterns, each reference pattern precisely corresp. to the fault pattern formed with a certain synchronisation fault appearance. The link is such that its result value represents a measuring number for approximation between the fault pattern and each reference pattern. USE/ADVANTAGE - For digital transmission systems, without need of extra synchronisation signals, but using only fault correction properties of cyclic code.

Patent DE-4140742-A1 (DE)
Inventor: SCHMIDT WERNER ARTUR KARL EUGE
IPC: H04B7/26
Filed: 1991-12-11
Abstract: A method for operating a digital cellular mobile communication network for supplying mobile stations, located at continuously changing locations, from radio base stations via signal currents, uses a delay correction device which corrects for the delay differences of the signal currents produced by the radio propagation. The delay correction device consists of an adaptive transmission predistortion circuit which is arranged in the radio base station, it being possible for the distortion of the transmission predistortion circuit to be varied in accordance with the delay of the signals from the mobile station to the base station. As a result, the [lacuna] consuming relatively high power can be [lacuna] or greatly simplified or switched off, as a result of which the energy balance of the mobile station is improved and the production costs are lowered.

Title: Printed circuit board with solder contacts for edge mounting of auxiliary PCB - provides for metallised contacts to be left when auxiliary PCB is sepd. from basic board
Inventor: KRAHL BURGHARD DIPL ING
IPC: H05K3/00
Filed: 1991-12-14

Inventor: SPARRER GERALD DIPL ING
IPC: G01B9/02
Filed: 1992-03-11
Abstract: The arrangement for direct comparison and calibration of laser interferometers, or LIs, for length measurements uses an LI as a standard.

IPC: B60K15/04
Filed: 1992-12-23
Abstract: The filler port is covered by a cover (7) hinged at the edge of the filler pipe on the vehicle. A retaining catch (9) secures the cover. The edge of the filling nozzle (22) is shaped (23) to grip the release mechanism and also acts as a closing mechanism for the cover.The edge of the nozzle displaces a spring loaded catch (16) to release the security catch (9) for the cover.

Title: Manually adaptive suspension with adjustment fittings for bicycles
Inventor: ELLSAESER DIETRICH GERHARD
IPC: B62K25/28
Filed: 1993-05-27
Abstract: The system affords a shock absorption solution which is of simple construction and will cope with the demands of cycling. The combined adjustability of the damping curve, the damping and the spring pretensioning makes it possible for each cyclist to adjust his driving system to the ratio of his body weight to his pedalling force. The pronounced progressive action makes further rebound possible in the event of bounces thus partially increasing the effective spring travel. The system combines optimum lateral stability with a low system weight.
