Title: Electrolytic emulsion additive - comprises unsatd. plant oil, lead-free petrol and mineral-enriched water for altering combustion stage of hydrocarbon material
Inventor: STUTE HANS-JOACHIM
IPC: C10L1/32
Filed: 1992-04-08
Abstract: Direct colloid determined conversion of fluid fuels produced in a refinery, e.g. petrol, kerosene and diesel, to a state in which they are consumed in internal combustion engines to produce and exhaust gas, which is practically harmless ecologically is claimed. A special emulsion is used comprising mineralised water, unsatd. plant oils and lead-free petrol which produces an auto-catalytic, kinetic and electrodialytic alteration of the hydrocarbon content of the fuel. Oxygen is applied and hydrogen is chemically integrated in the cyclic hydrocarbon, whereby a catalytic sec. combustion with hydrogen and oxygen is activated in the engine. This alters the harmful materials in the exhaust gas so that they are environmentally harmless, preventing the formation of lead acids, cyanic acids and sulphur oxide in the catalytic convertor. USE/ADVANTAGE - To render the exhaust gas of an internal combustion engine environmentally harmless.

Title: Device for pressing the sealing plugs into spare chambers in a plug
Inventor: NAHRWOLD FRANK
IPC: H01R13/52
Filed: 1993-03-10
Abstract: Until now, sealing plugs have been pressed manually into spare chambers, which are not provided with cables or cable ends, in order to close these chambers off in a sealed manner. Since this is very time consuming and cost-intensive, the new device is intended to make it possible to automate the pressing-in process. To this end, a separating device (1) is provided which is connected to a pressure tube (19) to which compressed air can be supplied and which opens into the chamber which is to be fitted, into which pressure tube (19) a sealing plug (21) can be guided. This design refinement of the device now makes it possible to dispense with manual insertion of the sealing plugs, so that considerable cost savings result. <IMAGE>

Title: Silent pneumatic damper to control closing of door
Inventor: MENKHOFF KARLHEINZ
IPC: F16F9/44
Filed: 1994-03-22
Abstract: The damper has a piston (3), which when pushed into the cylinder (1), must pass through the seal. It is damped by the compression of the air in the cylinder.
