Title: Pelletised fuel for water reactor - has fission product duct through pellet centres connected to grooves at periphery
Inventor: WUNDERLICH FRANK DIPL PHYS DR
IPC: G21C3/17
Filed: 1978-05-26
Abstract: Fuel rod, esp. for a light water reactor, consists of a sealed tubular can containing a stack of fuel pellets and a helium atmosphere. Each fuel pellet has a central bore to permit gaseous fission products to escape to the accumulation spaces within the can. The cylindrical outer face of the pellet comprises a number of (vertical) grooves designed to offer min. hinderance to heat transfer between pellet and can. These grooves are pref. connected to the central bore by depressions or grooves on the upper and/or lower faces of the pellet. In additions, there may be radial bores connecting the vertical grooves on the outer face of the pellet to the central bore. Arrangement conveys fission products away from the gap around the perimeter of the pellet and thus prevents precipitation of these prods. there, which can lead to a deterioration in the heat transfer between pellet and wall and consequent damage to the can.

Title: Friction reduction system for boat - uses layer of gas ejected through slots in hull to act as lubricant film
Inventor: BIESTERFELDT HARALD
IPC: B63B1/38
Filed: 1978-07-17
Abstract: The technique for reducing the frictional resistance of a buoyant body travelling over water uses a layer of gas to separate the body- and water-surface and to act as a low viscosity lubricant film. This gas can come from the propulsion engine exhaust or a forward-facing air intake; is discharged through one or more transverse slots in the hull underside. The hull shape is designed to prevent sideways escape of the gas, or alternatively the boat is fitted with skids parallel to the keel for that purpose. Speed-of-passage driven wind- or water-wheels can power flow augmenting blowers.

Title: Solar energy power generating plant - has solar heat collector rotatable about long axis, whose rear is heat insulated and mirrored
Inventor: RENZLAND WOLFGANG KARL
IPC: F24S90/00
Filed: 1979-07-05
Abstract: The solar power plant converts the solar energy into mechanical and electric energy without focussing arrangements, using a compression power mechanism in a closed system with a low boiling point and easily evaporable medium. It contains a heat collector, functioning alternately as a condenser. The heat collector is rotatably mounted on a long axis about which it can rotate through 180 deg. During cooling it experiences a 180 deg. rotation upwards. During this cooling phase two working elements (4,1) are at one end hinged to a leverage (4,2) and at the other end to double connecting rods. Thus the construction or expansion imparts a motion to an axis, driving a generator via a gear train, while the point of gravity of the generator plant lies on the axis of rotation. The rear side of the heat collector is thermally insulated and mirrored, the cooling taking place when this side turns upwards.
