  • Patent number: 5215323
    Abstract: By incorporating an infinitely adjustable, variable speed transmission unit into a bicycle driving mechanism, it becomes possible to vary the speed of the bicycle in a very easy and continuous manner from any predetermined maximum value of rotation in the forward direction to zero. By using a similar, infinitely adjustable, variable speed transmission unit in combination with a standard, two speed and reverse gear box, a very efficient automotive transmission system is also achieved, having a stepless speed control with a large power input.

  • Patent number: 4913222
    Abstract: A heat recovery unit for use to preheat fresh air with hot air produced in an industrial process, such as the hot air exhaust from a dryer of a pulp and paper mill. The recovery unit makes use of water circulating from one air/water heat exchanger tank to another air/water heat exchanger tank as heat transfer medium. Hot air whose heat is to be recovered at least in part, flows past a set of revolving discs of metal partially immersed in the water flowing in one of the heat exchanger tanks. The portions of the discs which are exposed to the hot air above the water level transfer the heat they recover to the flowing water. The water which is so heated passes into the other heat exchanger tank where it raises the temperature of an identical set of revolving discs which in turn heats a fresh air intake to provide warm air. The main advantage of this recovery unit is that the heat recovery conditions can be easily adjusted to fit any seasonal fresh air change.

  • Patent number: 4566860
    Abstract: The present invention relates to a method and to systems which can be used to recover waste heat available in the form of low pressure steam by compressing such steam in a compression system of the liquid piston type to provide steam of a higher pressure. The higher pressure steam can then be more advantageously used in industrial processes.
