Title: Cooling device for semiconductor rectifier - consists of hollow shaft with radial or axial fan blades to circulate cooling air
Inventor: MAASLAND HANS-HERMANN
IPC: H01L23/40
Filed: 1979-07-18
Abstract: The cooling device for the semiconductor rectifier may be a fan of either axial or radial type. The rectifier unit may be mounted inside a hollow shaft in a generator system. In particular, it may be used to rectify the current from the windings of an excitation current generator in a synchronous machine. Where an axial cooling fan is used, the individual blades are fastened or formed on the outside of the thin-walled hollow shaft. There is a bolt with its axis at right angles to the thickness of the wall of the shaft, holding a support for the rectifier. This support holds a further bolt which is connected to the rectifier element. The rectifier element rests against the side of the shaft.

Title: Synthetic formation of defect-free images - by superimposed blurring images of defect on reconstituted multiple perspective images
Inventor: LINDE ROLF ING GRAD
IPC: A61B6/02
Filed: 1980-11-10
Abstract: A method and arrangement for tomographic synthetic image formation involve passing light through the object (6) from several positions to form perspective images (11) on a recording medium (10). The images are smapled by placing a lens at the source positions so as to superimpose them on a light sensitive layer, thus recording the visual image. The arrangement is designed to produce a natural locking image without defects. The perspective image is partially overlayed by a blurred image derived from the perspective image and of an intensity corresp. to that of the defect present in the image. The blurred image may be conducted by superimposing several visual images lying in front of and/or behind the layer image. This may involve moving the recording medium, lens and/or light sensitive film along the optical system axis.

Title: Cleaning device for air coolers
Inventor: STOG WILHELM ING GRAD
IPC: E21F3/00
Filed: 1981-04-04
Abstract: Air coolers which are used in underground mining for cooling the mine air are subjected to considerable contamination because the air to be cooled is usually dust-laden. A cleaning device to be operated intermittently consists of one or more nozzle beams (18) allocated to one tube assembly each. The nozzle beam (18) has two or more arms (19, 20) and is rotatably mounted on the housing (2). This nozzle beam or the nozzles are designed in such a way that the arms automatically rotate when cleaning water is admitted. The cleaning water is thereby distributed evenly over the tube assembly. In the event of considerable contamination, identical nozzle beams (18) can be arranged at the various walls as well as at the top (3) or at the base (6). <IMAGE>
