Abstract: This is mainly a one-cylinder environmental friendly two stroke engine with a lubrication and a gas control mechanism similar to a four stroke engine. An additional rotation inside of a cylinder of a piston making a stroke motion is utilized for a better gas control mechanism. Control edges on the rotating piston open and close ports in the cylinder in the right sequence, most importantly the exhaust port will be closed prior to the opening of the transfer port. The piston with the rigidly connected L-shaped piston rod rotate around the axis of symmetry of the piston by a rotating spherical bearing rigidly, but eccentrically connected to a rotating shaft. A certain angle between the shaft and the axis of rotation of the piston creates also a stroke motion. An oil-ring around the piston rod works in the same way as by a four stroke engine.

Abstract: To protect moveable—mostly sliding parts from dirt porous filter material is placed in a closest way directly on one of the moveable partners; for instance directly in both fronts of a ball bearing running submerged in sea water to repel and absorb dirt particles on the way to the inner rolling parts. This will extend the service live under difficult conditions. In case of a mechanical shaft seal a filter ring is placed directly besides the sealing ring sliding together on a seat ring. Such filter ring protects the sensitive sliding surfaces much more completely than dirt rings in use, because they not only repel dirt, but absorb single dirt particles in its pores even in the sliding surface.

Abstract: This flow controlling device is a self regulating, reusable blowout preventer or smart pipe plug by limiting the flow in a pipe to a predetermined volume. This flow controlling device or BOP consists mainly of a tapered compression spring in a pipe. The spring measures the dynamic pressure, get compressed by increasing dynamic pressure and closes simultaneously and gradually the cross section for the flow. It closes automatically the pipe completely at a high pressure spike and opens up again after the pressure is normal again. This BOP can be placed deep in the casing of an oil well. It accommodates the drill stem and it works without any human interference. A modified device can be used in any sort of pipe and any flow as a pressure spike preventer (PSP) and also as a smart pipe plug (SPP) manually operated or via remote control.

Abstract: This invention relates to rotary piston machines with a positive displacement principle, pressure-tight work chambers and a strong piston actuating mechanism without power transmitting bearings. A piston rotor is rotationally coupled via its pistons or plungers, which reciprocatingly move in the cylinders of a cylinder rotor. Both axial and radial machines are included having a short stroke motion, but only in a co-rotating system. No oscillating mass power exists. This new piston actuating concept is applicable for all machines having at least one rotating pair of piston and cylinder. On top of the wide variety is an axial piston machine with a self-aligning pulling piston actuating mechanism and a quasi complete hydrostatic pressure balance of all movable parts including an outgoing shaft.

Abstract: A new kind of rotary piston machine with sealed work chambers and a wear resistant driving mechanism. Pivotal pistons move within respective cylinders and both the pistons and the cylinders revolve about circular orbits which are relative to one another. Both pistons and cylinders are included in a single piece rotor of unitary construction and can have either an axial or a radial configuration. Single-cylinder or multi-cylinder engines are included. This invention eliminates the necessity of piston bearings and thus, provides a wear-resistant, oil-free, driving mechanism. This invention further unites the sealing performance of the classical piston machine with the kinematic qualities of the rotary system.

Abstract: A rotary piston displacing machine for use as a pump compressor or power engine, as well as a hydrostatic coupling. The machine has a disk-shaped rotor rotatable in a housing, several similar diametrically opposed rotary vanes which penetrate the annular groove of the working space, which vanes can be joined or formed together in a second rigid rotor, the impeller, the disk-shaped rotor having a rotational axis forming an acute angle with the axis of the impeller. The disk-shaped rotor is positioned obliquely on the working space and is provided with radial slots for receiving the vanes which reach down to the bottom of the working space to sealingly lock the adjacent working chambers formed in the working space. The displacement operation takes place by the rotation of the vanes and the changing cross-section of the groove of the working space. If the cross-section of the working space approaches zero on one point of its periphery, i.e.
