Title: Current limiting ignition circuit for IC engine - uses Zener diode to hold base bias of drive transistor for ignition coil prim. winding
Inventor: NOBE HISANORI
IPC: F02P3/05
Filed: 1991-06-28
Abstract: The ignition circuit has a drive transistor (14) controlling a Darlington pair (17,19) which switch the primary current of the ignition coil (20). A Zener diode (31) linked to a resistor chain (13,30) holds the base of the drive transistor at the optimum setting irrespective of changes in the battery supply (8) voltage. This prevents the circuit from oscillations and ensures accurate ignition pulses. The ignition pulses are initiated by an e.m. control element (1) whose output is passed through a comparator (3) to generate control signals for the drive transistor. The primary current is held at the selected level by a series resistor (22) and a control circuit (23). ADVANTAGE - Stable ignition despite variations of battery voltage.
Patent DE-4123194-A1 (DE)
Inventor: HUVER THOMAS DR
IPC: C08F2/00
Filed: 1991-07-12
Abstract: Compositions of this kind begin to polymerize as soon as the components are mixed together. In order to widen their field of application, they have been made stable to storage. To this end, O2 and peroxides must be removed. Suitable ways of doing this are degassing and the addition of a deoxidizing agent. This makes controlled polymerization possible: thus adhesives and sealing, coating and moulding compounds, for instance, can first be rendered storage-stable for a period of several months, which is a suitable length of time for normal use, and they will then cure within an hour at room temperature simply on admission of air.

IPC: D06F34/18
Filed: 1991-12-13
Abstract: A method of determining operating parameters of a program-controlled washing machine with a resiliently mounted water container (1) housing a laundry drum (2) comprises ascertaining the height position of water level in the container as a measurement value with respect to a fixed reference point in the machine on each occasion of introduction of water (29) into the container and laundry (28) into the drum. The ascertained values are stored in a computer where they can be processed to determine parameters such as mass of the dry laundry, type of laundry, water level, water quantity absorbed by the laundry and residual absorbed water quantity after spinning. Such parameters can then be utilised in control of the machine operation. <IMAGE>
Patent DE-4141469-A1 (DE)
Title: Operating optical sensor for detecting objects - using periodically transmitting light source and receiver, evaluation unit extracting useful signal from measurement signal using noise signal measurements
Inventor: KAPPELER OTMAR DIPL ING
IPC: G01V8/12
Filed: 1991-12-16
Abstract: The method involves transmitting a light signal to a receiver which detects essentially no light when no object is present in a detection region. When an object is present, the receiver receives light by reflection or transmission from it and a connected receiver signal evaluation device produces an object detection signal. Before and/or after the light signal is transmitted, a noise signal is received by the receiver. The information derived from the resulting receiver signal is used to extract the useful signal from the measurement signal, e.g. using linear interpolation. ADVANTAGE - High noise immunity, esp. in presence of periodic noise, e.g. stray light or electromagnetic radiation.
