Patent DE-4233419-A1 (DE)
Title: Production of windings for transformers and inductance coils - has adjustment provided to vary diameter of winding former using cone-shaped elements to radially displace supports
Inventor: WEBER HANS DIPL ING
IPC: H01F41/098
Filed: 1992-10-05
Abstract: The production of electrical windings requires an adjustable unit that provides a variable winding former. The unit has a number of radial support arms (14) spaced around a winding axis. Each arm has fixed supports (24) with rollers (26) that engage the tapered surfaces of cone shaped elements (16) having a central spindle (22). By rotating the central spindle, the cones may be axially displaced and this causes the support elements to move radially outwards to vary the diameter. USE/ADVANTAGE - Improved adjustment for size of winding.

Title: Assembly separating solids and fluids in suspension - by using micro:filtration fixed pore membrane from spirally-wound wire, uses no pore size setting mechanism reducing mfg. costs and eliminates pore dimension errors
Inventor: SIEGFRIED HANS GUENTHER
IPC: B01D63/04
Filed: 1992-10-06
Abstract: An assembly which separates fluids and solids in suspension has a spiral-shaped wire tubular micro filtration membrane whose pore size can be constructed to an accuracy of less than one micron. The novelty is that the pore size of the micro filtration membrane (2) is selected to match the requirements of the fluid under treatment and that no adjustment mechanism is used to vary the membrane pore size. Also claimed is the mfr. of the micro filtration membrane. The tubular micro filtration membrane (2) is made of spirally woven wire at a predetermined tension so that the required pore size remains constant (claimed). USE/ADVANTAGE - The assembly separates fluids and solids in suspension. The assembly is simplified in comparison with previous units and precludes errors arising from incorrect settings associated with adjustment mechanisms applying pressure or tension to the coil.

Title: Method and device for measuring the radon content in ground gas
Inventor: HORN WOLFGANG DR ING
IPC: E02D1/00
Filed: 1993-03-25
Abstract: For measuring the radon content in ground gas, especially for building-site inspection, it is known to suck the ground gas out of a borehole which is sealed from the external air, via a measuring tube using a suction pump, and to supply it to a measuring station for measuring radon. The novel method and the device are intended to make it possible to determine the availability of radon in as big a ground volume as possible in the ground under different conditions and to ascertain the effects on the buildings to be erected. A measuring tube is inserted into a bore of predetermined depth in the soil and the ground gas is sucked out, supplied to the measuring station for measuring radon and the radon content in the ground gas is there continuously measured and registered, the negative pressure generated by the suction pump being simultaneously continuously regulated and thus adjusted to predetermined values, the negative pressure and the volumetric flow of ground gas produced thereby being measured separately and registered in a characteristic curve. Measurement of the radon content in ground gases, especially those sucked out of the soil during building-site inspections. <IMAGE>

Title: Method and apparatus for gear-changing in transmissions with tensile transmission elements
Inventor: KWAUKA GERD-GEORG DR
IPC: B62M9/10
Filed: 1993-07-01
Abstract: The technical object is to find methods and devices which make it possible to change gear in transmissions with tensile transmission elements from one transmission stage to the other under full load without twisting the tensile transmission element. There should also be no reduction in the high efficiency of positive transmissions. The associated structure must be of simple and space-saving construction. A reversal in the direction of rotation must also be possible. The solution consists in that the wheels for the tensile transmission elements are divided into segments and the segments are moved into the range of action of the tensile transmission element at precisely the moment at which they are not subjected to a load by the tensile transmission element. A space saving can be achieved by virtue of the fact that the wheel segments for the tensile transmission elements are mounted centrally on levers and are nested one inside the other. Applications are in the areas of bicycle and motorcycle drives and of motor vehicles of all kinds and in technical drives, i.e. wherever a highly efficient close-ratio mechanical gear change that can be switched under full load is important.

Title: Illumination device
Inventor: CROMBACH PETER
IPC: F21V8/00
Filed: 1993-07-27
Abstract: An illumination device is described for illuminating a plane useful surface in accordance with a predetermined characteristic. The device is distinguished by the combination of a strip-shaped light guide with a glass body, the light inlet surface and the light outlet surface of the glass body consisting of optically active surfaces which are pressed so as to be shiny. These optically active surfaces may either be aspheric surfaces, but they can also be hand-forged surfaces, or they may also consist of a combination of both types of surfaces. The light inlet surface and the light outlet surface of the glass body may in particular be at an angle relative towards each other. In this case, the glass body has a mirrored surface which deflects the illumination beams from the one surface to the other surface.

Title: Antimicrobial material
Inventor: BOETTCHER HORST PROF DIPL CHEM
IPC: A23L3/3508
Filed: 1993-08-31
Abstract: The invention describes the preparation of materials for the delayed release of antimicrobially active substances, resulting in a reduced exposure of objects which are in contact with the materials to antimicrobially active substances and carrier material components, and, on the other hand, an improvement with regard to the long-term availability of the active substances. The delayed release of active substance is achieved by incorporating the active substances into a diffusion-inhibiting metal oxide matrix, for example by sol/gel technology or by co-evaporation. Advantageous applications are the preservation of foodstuffs and the disinfection of any desired object.

Patent DE-4404073-A1 (DE)
Inventor: LINZENICH UWE
IPC: H01H71/46
Filed: 1994-02-09
Abstract: The invention relates to a low-voltage power switch with a relative auxiliary switch which is actuated as a signalling switch only when the generally multi-pole low-voltage power switch is triggered. The problem to be solved is that of controlling relative auxiliary switches simply and independently of the switch latch. To this end, the switch latch is designed in such a way that the included angle of the movable contacts or the switching spindle (18) is greater in the "triggered" than in the "off" state. A radial extension (60) is arranged on the switching spindle (18) in such a way that, in the "triggered" state, it engages a fixed pivoted lever (68) which itself is effectively connected to the prestressed actuating pushrod (66) of the relative auxiliary switch (56).
