Patent DE-4341826-A1 (DE)
Title: Vehicle battery charge evaluation procedure
Inventor: LANGNICKEL WOLFGANG DIPL ING
IPC: G01R31/36
Filed: 1993-12-08
Abstract: The charge evaluation system uses the measured voltage during operation of the IC engine starter motor and the measured battery temp. The dead point timing of one of the reciprocating pistons is detected and the voltage at this point is recorded for conversion into a value characteristic of the battery charge.Pref. the dead point timing is determined by monitoring the current provided by the battery (13) which is differentiated, the battery voltage being recorded when the current characteristic exhibits a relative extreme value, or a turing point. The charge measurement is terminated in accordance with a given criteria, e.g. elapsed time or a defined engine revs.

Patent DE-4400865-A1 (DE)
Title: Optimising stereo reproduction in FM receiver
Inventor: KRAMER WOLFGANG
IPC: H04H1/00
Filed: 1994-01-14
Abstract: The method involves introducing a sliding mono blending when audible hiss occurs. The amount of mono blending depends on a quantitative value of the received signal, which is derived from the received field strength and modulation content of the audio frequency signal. The mono blending is optimised with regard to channel separation and signal-to-noise ratio. The threshold at which mono blending begins can be altered to take account of the type of broadcast, e.g. rock, pop, classical music or news. This information can be derived from RDS data. The amplitude and difference signals of the audio signal can also be used as determining values.

Patent DE-4436323-A1 (DE)
Title: Automatic seat belt winder
Inventor: SPECHT MARTIN DIPL ING
IPC: B60R22/44
Filed: 1994-10-11
Abstract: The winder has a shaft (4) for a spool with which a safety belt can be unwound and rewound in the normal manner, under the influence of a rewind spring. A mechanism (20) is also provided to superimpose an additive or subtractive force on the rewind spring, which is dependent on the length of unwound belt. The supplementary force may assist the normal force over a first range of unwinding angles, and may resist it over a second range, and may also have a dead point with no overall effect. A four bar mechanism (8-11) and a toothed rod (6) transmit the effect of a spring (17) in the unwind or rewind direction to the shaft of the winder.
Patent DE-4438227-A1 (DE)
Title: Sawn timber etc. handling and compacting machine
Inventor: BELTER ADOLF DIPL ING
IPC: A01G23/00
Filed: 1994-10-26
Abstract: The machine has pivotal flats (10), curved round the drums, which swivel towards the drum axis in the pick-up region (2) and out to the drum peripheries in the transfer region (3). Fixed entraining elements (1) fitted to the drums are closed off in the intervals between the elements by the flats. The flats swing in and out to drum axis and periphery respectively, have end-mounted rollers (5) and engage tensile springs (9) hinged to the drum cylinder shaft. The rollers associate with controlling cams (7) mounted in the main framework. The edges of the entraining drivers (11) should be profiled. As the drums rotate so the flats ride out via their rollers and the control cam to the drum periphery and back again so as to engage and grasp the gathered material, e.g. sawn timber, as against the compacting movement when the flats between the drums move steadily out to the periphery so as to produce a smooth faced drum system hence the timber etc. can be transferred to the offtaker belt etc.

IPC: H01M8/04
Filed: 1994-11-11
Abstract: A protection circuit (11) against gas shortage in a fuel cell has the cell (1) connected to an inverter (2) for the load and a voltage regulator (3) working on the output of the inverter. The protection circuit is connected to the latter. There is a calculation stage (12) for a permitted excess current, based on a fuel  coefficient and the output current of the cell, so that an earlier value can be updated. There is a response speed control stage 913) which eliminates fluctuations in this calculated excess current value. There is an overcurrent limiting stage (15) which gives a signal to reduce the voltage at the regulator when the output current from the cell exceeds the permitted value.

Title: Haematogenic oxidation therapy device
Inventor: LAATSCH KARL PETER DR MED
IPC: A61M1/36
Filed: 1994-12-23
Abstract: The device has a similar construction to the conventional design for this type of therapy but instead of having only one apparatus for producing UV light with a wavelength of 253.7 nm a separate light source is available with a wavelength of 258.59 \!1 nm. In use the blood is mixed with oxygen in the device and then irradiated with UV light of a wavelength of 253.7 \!1 nm for approx. 30 minutes. The light source is then removed and a second light source is used with a wavelength of 258.59 \!1 nm. The intensity of both light sources is the same. The gas introduced to mix in the blood to create a foaming consistency is oxygen but an oxygen and ozone mix can be used instead or other inert gases. The treated blood is then injected back into the veins or the muscle of the patient.

Abstract: L'invention concerne un procédé et un dispositif pour la correction d'erreurs de position d'un rayon lumineux (2) diffracté par un dispositif de diffraction (17) présentant au moins une surface formant un miroir (18) au-dessus d'une surface (23), rayon qui se déplace perpendiculairement à la direction de lignes par rapport au dispositif de diffraction (17). Le rayon lumineux (2) est produit par une diode-laser (1) qui est déplaçable perpendiculairement à la direction du rayon lumineux sortant (2), en fonction des valeurs de correction. Avant la mise en service proprement dite, on mesure, pour chaque surface à miroir (18) du dispositif de diffraction (17), un certain nombre d'erreurs de position du rayon lumineux (2) en direction des lignes (erreur de position X) et perpendiculairement à celle-ci (erreur de position Y), sur des points de mesure (32a; 32b; 32c) sur la surface (23), orientés en direction des lignes. Au moins une valeur de correction X et une valeur de correction Y sont fournies pour chaque surface à miroir (18). La diode-laser (1) est déplacée en fonction des valeurs de correction X et des valeurs de correction Y, de telle façon que le rayon lumineux (2) frappant la surface (23) subisse des déplacements de correction dans la direction des lignes et perpendiculairement à celle-ci, en vue d'éliminer l'erreur de position X et l'erreur de position Y. Les valeurs de correction sont modifiées par vérification simultanée des erreurs de position, jusqu'à ce que lesdites erreurs de position soient compensées. Les valeurs de correction déterminées de cette façon sont mémorisées et distribuées pendant l'exploitation proprement dite, en vue d'assurer la compensation en continu des erreurs, en synchronisation avec le déplacement du dispositif de diffraction (17).
