Title: IC engine starter motor circuit - has NTC resistor in series with starter relay for controlled engagement of pinion
Inventor: SMOLKA HELMUT
IPC: F02N11/08
Filed: 1991-07-05
Abstract: The starter motor (23) is operated by a relay (22) with temperature independent control. This is achieved by a series connected NTC resistor (20) in the relay coil circuit. The voltage applied to the relay coil is constant over a temperature range and ensures that the relay moves the starter pinion into mesh at a controlled rate, before the starter motor is activated. The characteristics of the NTC resistor are selected to counteract the resistance changes in the coil due to thermal variations. The NTC resistor operates from -30 deg.C to 160 deg.C. ADVANTAGE - Even engagement of starter pinion, less starter noise, less starter wear.

Title: Oven procedure for cooking - measuring cooking temperature at successive time intervals and giving signal when weighted average temperature reaches set point
Inventor: SCHROEDER MICHAEL
IPC: F24C7/08
Filed: 1992-09-18
Abstract: The oven for baking or roasting has a user-specified set point for the temperature inside. At the end of the process, a signal is generated.

Temperatures that are so low as not advance the baking or roasting process significantly are rated as zero. The time intervals are all shorter than one minute. The signal may be an optical or acoustic one. ADVANTAGE - Optimum cooking time depending on quantity of food.

Title: Door closing unit with dual rate spring action and electromagnetic trigger - has first compression spring for normal re-closing function and second stiffer spring to ensure positive closing in emergency
Inventor: JENTNER WOLFGANG DR
IPC: E05F15/20
Filed: 1992-11-04
Abstract: The door-closing unit with pneumatic or hydraulic damping via a piston (3) and dashpot has a cylindrical housing (1) containing a spring-operated closing mechanism which incorporates a first compression spring (4) and a second more powerful compression spring (5). The spring (5) is retained in compression between the moving plate (8) and housing end (1a) by the electromagnet (10) and armature rod (9). Normal manual opening of the door compresses the spring (4) via the rack and pinion (2) door-drive connected to the piston (3) and re-closing is entirely effected by the spring (4). An emergency signal from e.g. a smoke-detector, de-energises the electromagnet (10) resulting in both springs (4,5) exerting a strong closing action. USE/ADVANTAGE - Provides gentle opening/closing action during normal operating conditions which is considerably increased in response to emergency signal to ensure positive closing. Normally energised electromagnet fails safe if power-supply fails.

Title: Reusable plastic or metal container - has blow moulded cover of desired shape with sprayed on lining of resistant polymer which can be stripped off so that cover may be reused
Inventor: LEUKEL KLAUS
IPC: B65D25/16
Filed: 1993-01-30
Abstract: A container has a plastic or metal cover of the final shape with an inner removable and replaceable protective liner made of material which is unaffected by the contents of the container. The liner adheres to the internal side of the container and is a film which can be stripped off mechanically. ADVANTAGE - The inner liner can be readily removed without contaminating the outer covering. The product is partic. a plastic blow moulding and its liner provides such protection that the outer cover layer can be repeatedly used. In an example, a barrel (1) which is a plastic blow moulding made of e.g. polyethylene, polypropylene etc., is lined with a protective layer (5) of e.g. a coating material in solvent forming a film which can be torn off without being damaged. This lining (5) is produced by spraying from a revolving nozzle (4) on to (pref.) the moulding (2) while the latter is still hot. The solvent used can be drawn off. Its film lining (5) can be stripped off when the container (1) is e.g. refilled, or filled with a different liquid, or is disintegrated for recycling. If it is water-based it can be sprayed into the blow moulding just before the latter is completely finished. It then cools off as the moulding cools.

Title: Electric charging, coagulation and filtering of particles suspended in fluid, e.g. air, water, oil, cleaning liq, working liq - arranging electric charging electrode in passage region through which fluid flows, electrode being made of conducting material
Inventor: INOUE NOBORU
IPC: B03C5/00
Filed: 1993-03-16
Abstract: The charging electrode (X) works as a filter layer. A counter electrode (Y) is arranged in the passage region opposite the charging electrode (X). A DC voltage is applied between the charging electrode and the counter electrode, in order to charge the entire filter layer so that a coulometric force, produced by the DC voltage, reacts over a large area on the suspended particles (particulate). The particles are suspended in the intermediate space between the two electrodes, in order to allow the particles to coagulate to form coarser particles. The coarser particles are delivered in the filter layer with the flowing of the liq. and the particles can flow through the filter layer, and the particulate (suspended particles) are filtered out. ADVANTAGE - Fluid to be processed flows unhindered in filter. Greater amts. of fluid can be filtered. Gives high filter reaction without applying higher voltage. AC or DC voltage can be applied.
