Title: Faulty ignition determination system for IC engine with microcomputer - includes circuit for giving reference duration signals which represent crank angle positions corresp. to ignition cycle of engine, also includes time relationship detector.
Inventor: ISHIDA YASUHIKO
IPC: G01M15/11
Filed: 1993-06-02
Abstract: The system for an IC engine (1) has a time relationship detector determining the relationship of time durations corresp. to set angle intervals. These intervals lie before and after a determined reference angle of a reference duration signal, which is given by an output unit. A faulty ignition judgement unit is provided for comparing the relationship of the time durations with a set value. The judgement unit establishes that a faulty ignition has occurred, if the relationship of the time durations is greater than the set value. If the relationship of the time durations is not greater than the set value, no faulty ignition has occurred. A unit alters the detection of the time corresp. to the set angle intervals, corresp. to the engine revolution speed. ADVANTAGE - Simple construction. Occurrence of faulty ignition can be determined in wide operating range of engine.

Title: Conveyor with holding cells
Inventor: BALLUF THOMAS DIPL ING
IPC: B65G47/26
Filed: 1994-08-16
Abstract: The roller conveyor has the rollers driven by friction contact with a drive belt. Solenoid-operated servo cylinders (10) control the friction contact in the holding cells (4, 8, 9). When the drive belt is lowered away from the drive rollers a brake belt stops the rollers.  The solenoid valves are interlocked by a simple logic which enables the load items to be stopped in each cell, with the same spacing to the other load items. The entry of the first load item into the leading cell connects all the solenoid valves to the supply while a simple OR logic enables each cell to operate independently. This replaces a group drive for the servos.

Title: Fibre optic arrangement for measuring the strength of an electric current
Inventor: PEIER DIRK
IPC: G01R15/24
Filed: 1990-07-12
Abstract: In a fibre optic arrangement for measuring the strength of an electric current using the Faraday effect, the magnetic field surrounding the current-carrying conductors (1) influence the polarization condition of the light which travels through the core of an optical fibre (2) surrounding the conductor (1) in the form of a winding (3). A reflecting surface (5) is provided at one end (4) of the optical fibre (2) and the light enters and leaves at the other end (6). In order to exploit the advantages of the twisting of the optical fibre while reducing all other measurement errors, circular double refraction is conferred in a known manner on the optical fibre (2) by twisting it about its longitudinal axis, and the end (4) of the optical fibre (2) with the reflecting surface is arranged in the immediate vicinity of the other end (6) so that the whole optical fibre (2) forms an almost completely closed loop.

Abstract: Il est proposé un procédé pour l'amorçage d'une lampe à décharge gazeuse déterminant la fréquence de résonance d'un circuit oscillant d'amorçage (11, 12, 13) attribué à la lampe à décharge (10) après l'intervention d'un signal d'enclenchement E de la lampe au moyen d'un signal d'excitation T dans un système de traitement de signaux (17). Ensuite, pour réaliser le processus d'allumage de la lampe à décharge (10), le système de traitement de signaux (17) commande une génératrice de tension alternative (16) interne à l'appareil de distribution (14) pour l'exploitation d'une lampe à décharge (10), afin de l'amener à la fréquence de résonance prédéterminée du circuit oscillant d'amorçage (11, 12, 13). Le système de traitement de signaux (17) est aussi sensible au processus de décroissement des oscillations excitées par le signal d'excitation T du circuit oscillant d'amorçage (11, 12, 13). Ce procédé permet d'une part de détecter des défauts de composants, et d'autre part d'augmenter la sécurité d'exploitation, car tout contact accidentel avec une ligne sous tension dans le circuit de la lampe peut être détecté et l'appareil de distribution (14) mis hors circuit.

Title: Pharmaceutically applicable nanosol and process for preparing the same
Inventor: WUNDERLICH JENS-CHRISTIAN
IPC: A61K9/20
Filed: 1992-12-04
Abstract: Nanosols and process for preparing the same allow colloidally dispersed solutions of scarcely water-soluble active substances to be stabilised with gelatine or its derivates, by partly or fully setting the iso-ionic point (IIP, equivalent to a neutral charge) between the gelatine and the surface charged active substance particles. In order to neutralise the charge of the system composed of active substance particles and gelatine, the surface charge of the particles is compensated by a corresponding opposite charge of the gelatine molecules. For that purpose, a determined charge in relation to the isoelectric point (IEP) and the pH value of the solution is set on the gelatine molecules. By stabilising in this way the practically monodispersed state thus generated, the Ostwald maturation of the colloidal particles of scarcely soluble active substance is strongly reduced. A new form of pharmaceutical administration having new properties can thus be obtained with generally scarcely water-soluble anorganic and organic compounds, in particular medicaments with a problematic bioavailability. Prefered medicaments are glibenclamide and 3-indolylacetic acid derivates, such as indometacin or acemetacin.
