Title: Water driven power generating installation - has walls narrowing stream course to increase water force on turbine blades
Inventor: NOERGAARD JAKOB
IPC: F03B17/06
Filed: 1975-02-18
Abstract: The construction makes it possible to extract energy from any stream without the use of a dam. A river with a bed (2) flowing between banks (1) is channeled into a narrower course by walls (3) parallel to the banks and diagonal walls (4) tapering from the parallel walls (3) out to the banks (1) at the inlet and outlet of the power generating section. The flow of water (5) is thus forced into a narrower cross section with a resulting increase in its propulsive momentum. A water wheel is placed in this section and obtains energy from the increased flow of water. The end and side walls (3, 4) can be movable to allow the passage of shipping when necessary.

Patent DE-2537639-A1 (DE)
Title: Shell and tube heat exchanger for sublimate recovery - with vapour flowing axially aong the outside of vertical finned tubes
Inventor: GUETLHUBER FRIEDRICH
IPC: B01D7/02
Filed: 1975-08-23
Abstract: Vertical exchanger has process vapour flowing outside the tubes, and the shell side is baffled so that this vapour flows axially along the tube walls which have longitudinal fins. The baffle holes are sized so that there is the same flow rate over each tube and the tubes are angled so that they are closer together at the bottom than at the top. Heat transfer medium flows inside the tubes. The appts. is used as condenser-melter for the batchwise collection of sublimable solids from a gas-vapour stream. As compared with conventional sublimate condensers where vapour flows across banks of tubes, there is minimum tendency to blockage of the rows first exposed to the vapour strem, and the uniform flow pattern and velocity distribution gives efficient use of all the heat transfer surface, with low pressure drop. Also the normal condenser design has flat walls suitable only fo r low pressure operation, and being readily damaged as a result of the frequent temp. cycles which take place, the new design obviates these disadvantages.
