Title: Inlet connection for injection moulding of liq. silicone rubber - has cooled front end with hydraulically operated needle valve
IPC: B29C45/28
Filed: 1990-05-04
Abstract: Feed valve has a hydraulically operated valve needle and a heat shield made of Ti alloy valve is in a housing which has a conical valve seat and a flat end in a flat ended projection. Valve is only cooled at the front region. Cylindrical heat shield is pressed into a recess in the valve and provides the only guide for the valve needle at the front. At the rear the needle has a guide and between the guides has a flat section which provides a channel connected to the feed. Heat flow between the valve and the mould is prevented by heat insulation which also allows some adjustment in the projection of the valve into the mould. Cooling water is supplied through a channel and tolerance (s) allows the valve seat to be maintained. USE/ADVANTAGE - Valve provides clean castings when used with liq. silicone rubber which has a low viscosity.

Inventor: BASTIAN UDO DIPL CHEM DR
IPC: B29C35/08
Filed: 1990-07-12
Abstract: In the state of the art, windings are fixed by impregnation with radically polymerizable compositions, followed by thermal curing. The process and device disclosed involve the curing by energy-rich radiation of the exposed surface of the impregnated windings between their impregnation and the thermal curing of the radically polymerizable composition. The emissions occuring during thermal fixation are thus strongly reduced, so that the operation is particularly harmless to environment.

Title: Breaking up old motor vehicles containing plastics parts - involves first breaking plastics parts away from bodywork
Inventor: SCHAETZING WOLFGANG DR ING
IPC: B09B5/00
Filed: 1990-09-19
Abstract: The breaking up of old motor vehicles with bodywork containing parts made of plastics, is carried out in the following way. Lines of weakness are formed in each plastics part in the region of its attachment to the vehicle bodywork.

Title: Heat-concentrating and heat-pumping solar collector - maximises efficiency by minimising heat losses to surroundings
IPC: F24S10/95
Filed: 1991-11-05
Abstract: A solar collector is covered with a pane which allows the passage of solar radiation and is held within a heat-insulated mount. A two-component fluid heat-carrying medium flows through the collector one of the media can be evaporated at the operating temp. the heat medium proceeds in a direction contrary to that taken by the heat towards the covering pane, and seeps through the heat insulation elements such as aquare or hexagonal honeycomb; the heat medium absorbs heat and increasingly evaporates; the evaporated components and the residual sole are led to the lower end of the collector along a light-absorbing area; and the heat medium is led through pipes or other suitable vessels behind the light-absorbing area so that it surrenders its residual heat in contraflow to the heat medium flowing downwards along the light-absorbing area. USE/ADVANTAGE - The arrangement maximises the efficiency of the solar collector by minimising heat losses to the surroundings.

Patent DE-4142155-A1 (DE)
Inventor: HECK KLAUS
IPC: F02D41/14
Filed: 1991-12-20
Abstract: A digital adaptive regulation system, eg for an i.c. engine, comprises a regulation loop 12.1, 14, 16.2, 11, 10 by means of which a measured parameter such as exhaust oxygen concentration measured at 12.1 is held constant against a preliminary control valve VS. The preliminary control valve is obtained by addressing table 13 with parameter values  alpha , n such as throttle angle and engine speed. The adaptive system 15 corrects the preliminary control valve at 16.1 using learnt correction values in each range of parameter values alpha , n. A new learning value is stored at 17 each time the parameter value range is visited, and a corresponding counter 20 is incremented at the same time. At intervals, for example when starting the engine, learning values with counters below a predetermined threshold (ie poorly adapted) are updated by calculation from other learnt values in adjacent parameter value ranges. Also, the counter values which are low, or all counter values may be reset below the predetermined threshold at intervals to allow repeated updating by calculation. <IMAGE>
