Patent DE-2332944-A1 (DE)
Inventor: BELLHOUSE BRIAN JOHN
IPC: B01D69/02
Filed: 1973-06-28
Abstract: A method and apparatus for effecting heat or mass transfer between two fluids through a membrane comprises a conduit for flow of one fluid, said conduit being at least partly defined by said membrane and the configuration of said conduit in a plane orthogonal to the general direction of flow varying periodically along the general direction of flow either inherently or in response to fluid pressure therein in such a manner that when said fluid is pulsated along the line of the general direction of flow a component of motion is induced therein which is mutually orthogonal to the surface of the membrane and general direction of flow. In preferred embodiments the conduit configuration varies periodically along the general direction of flow in order to give rise to separation and reattachment of flow at a multiplicity of zones within the conduit, whereby secondary flow is induced within said zones. The apparatus is particularly applicable to blood oxygenation and dialysis.

Title: Signal transmission method - signals are split into groups and distorted signal parts are retransmitted
Inventor: PREY GERHARD
IPC: H04L1/00
Filed: 1973-10-09
Abstract: Signals are split into groups with a number of signal elements, and cyclic counters at both ends identify individual signal elements or groups in each counting cycle. In order to ensure continuous signal flow, filling signals are transmitted when no signals are present for transmission. The sender end counter reading is transmitted within the filling signals, and the transmitted reading is compared with the reading at the receiving end. When the two readings do not coincide, the last signal or group of signals are transmitted. An assured identification of a single element or group of elements of a signal is made possible with reduced redundance.

Title: Hot clinker furnace cooling - uses air streams and high pressure water jets at hottest zone to loosen, spread and cool the bulk
Inventor: HECHENBACH HORST
IPC: F27D15/02
Filed: 1974-03-16
Abstract: The red hot clinker arrives in a plastic state from the relatively narrow discharge opening of the sintering furnace and due to high required outputs has to be spread out over a considerable width for quick cooling down. When the high pressure jets applied at the entry of the clinker onto the cooling grate hit the hot clinker an explosion-like disintegration of the clinker lumps accompanied by an intense steam generation follows, which loosens and lifts the clinker layer, hereby supporting the trend to spread out and being cooled by air streams introduced from under the grate. The jet pressures applied are in the region of 100 atm. The jet operation is controlled as far as duration and direction is concerned.
