  • Patent number: 7819092
    Abstract: A system that may utilize heat normally wasted in known internal combustion engines to heat a fluid is described. The fluid may be maintained under pressure and when the fluid is injected into a cylinder in place of fuel during the combustion stroke, it may expand thus driving the piston back down.
    Type: Grant

  • Patent number: 7041175
    Abstract: The invention relates to a method for the continuous production of hydrolytically broken down starch or hydrolytically broken down substituted starch products such as hydroxyethyl- or hydroxypropyl starch. The invention essentially consists of carrying out most of the hydrolytic breakdown in a pipe-shaped, temperature-controlled reactor having no mixing elements. The remaining breakdown is carried out in one or more reactors fitted with mixing elements (fine hydrolysis). The product obtained can be used both in the food industry and for medical purposes, especially as plasma diluent.

  • Patent number: 4248184
    Abstract: An improved two-cycle Diesel internal combustion engine is provided, whereby the intake and exhaust port passages are modified to provide greater circulation of the combustible fluids and air during the intake and exhaust cycles of the Diesel engine, respectively. The intake passages are so located in each piston and each cylinder to provide communication thereinbetween during the intake cycle with the piston at the bottom of its stroke which effects the exhaust cycle simultaneously substantially similar to a normal two-cycle operation. The intake passages in each cylinder communicate with intake passages in each piston which are connected to an intake flume port located epicentrically in the upper portions of each piston. The movement of the combustible fluids and the evacuation air is directed from the intake flume port and deflected off a conical protrusion in the upper surface of the cylinder, in order to promote circulation of the combustible fluids and the evacuation air, respectively.
