Patent DE-2510660-A1 (DE)
Title: Deicing cooling surfaces with local heating - using electrical surface heat to detach ice from surface
Inventor: RAUTENBACH ROBERT PROF DR ING
IPC: F25D21/08
Filed: 1975-03-12
Abstract: Heat exchanger on which ice or frost formation occurs has provision for local heating to remove this. The solid phase (ice or frost) is not completely transformed into the liquid phase but only a very thin layer on the surface adhering to the cooling surface is melted sufficiently to allow the solid to drop off. This is achieved by heating the layer on the surface but while this is occurring, it is not necessary to half the flow of coolant. The heat in this layer on the surface is obtd. by electrical resistance heating in a special layer or by a skin effect. This heating layer is formed by putting a thin layer of insulation on the cooling surface and laying a film of conducting material on top of this. Wires or wire mesh can also be used. For use in cooling applications where solids condense from gases esp. in cooling operations where frost and ice form e.g. in freezedrying. Often defrosting is achieved by general warming to melt the ice or by scraping. The system allows for the physical removal of solid ice merely by melting the surface which has adhered to the cooling surface. This saves energy and does not binder operation of the cooler because the coolant or refrigerant flow need not be stopped.

Title: Determination of position of radiation source - with radiation compared with reference source after passing rotating shutter
Inventor: DAMMANN HANS DR
IPC: G01T1/29
Filed: 1975-06-26
Abstract: The method is for determining the exact position of a point source of radiation, especially applicable to the determination of the X-ray source in tomosynthesis, in which the determination of the precise position of the source at each successive brief exposure is of great importance for the evaluation of the result. The radiation from the source passes through a stop (1) to define a narrow beam along the direction in which the position is to be determined, and this impinges on a detector (18). A reference source (7) similarly feeds a beam defined by the same stop (1) to a second detector (9), and means are provided to measure the time or phase difference between the two detector output signals.

Title: Cylindrical filter sleeve on support - consisting of synthetic resin coated plastic foam spheres bonded together
Inventor: HOERTEL WILLY
IPC: E21B43/08
Filed: 1975-08-09
Abstract: Filter medium consists of a packing or spherical particles made from plastic foam. These are coated with synthetic resin and bonded together by means of resin to form a rigid filter body. The individual particles can be made from polystyrene foam. To these can be added at least 8% quartz particles uniformly distributed and bonded with resin. Epoxy type resins are suitable for this duty. It can be used with a filler powder which has the same density as the resin. The filler can be constructed in the usual way with layers of differing particle size. Esp. for use in obtaining water from deep wells. Normally the filler is suspended by the pipe down the well and therefore its weight is of considerable importance. If plastic pipe is to be used, the wt. of the filter is limited because of the low tensile strength of the material. The use of plastic foam cores in the filter element allows a significant reduction in total wt. The relative amount of quartz allows the bulk density to be adjusted.
