Title: Voltage-regulated permanent magnet dynamo for bicycle - uses ferromagnetic particles displaced outward by centrifugal force to alter magnetic resistance
Inventor: VOLKRODT WOLFGANG DR ING
IPC: H02K21/24
Filed: 1990-04-14
Abstract: The magnetic flux return path for the permanent magnets is provided by ferromanetic particles, instead of by a solid yoke. The ferromagnetic particles are in the form of a magnetic powder or miniature balls which are displaced outwards in response to the centrifugal force for increasing the magnetic resistance of the magnetic circuit. This prevents any further increase in the induced electromagnetic voltage in the stator winding at high r.p.m. USE - Maintaining constant output voltage.

Filed: 1990-06-08
Abstract: Described is a process for treating the surfaces of workpieces (12) by using laser radiation (10) to heat edge zones, in particular for treating shafts for motor vehicles. The process calls for a laser beam to strike the surface (13) of the workpiece at an angle of incidence which is other than zero, producing an oval light spot (14), the beam being moved at right angles to it. In order to be able to work at high speed and produce products of high quality, linearly polarized laser radiation (10) is used and, to optimize the transfer of energy into the workpiece (12), the angle of incidence ( alpha 2) in at least one sector (15) of the light spot (14) differs from the angle of incidence ( alpha 3) in the other sectors (e.g. 16) of the light spot (14).

Title: Long-term heat store in basement of building - has concrete brick walls, deformable internal insulation layer, and water-proof sealing film
Inventor: NEUERBURG THOMAS
IPC: F28D20/00
Filed: 1991-05-22
Abstract: The highly insulated heat accumulator (1) is located in the basement of a building. It stores heat, which has been collected by collectors in the summer months, for use in the winter. The outer walls of the heat store consist of concrete or conventional brick walls. It contains a large volume greater than 20m3 for storage medium.

Any heat passing through the insulation is therefore distributed through the building. USE/ADVANTAGE - Heat accumulator can store large heat volume of period of months. It is easy and economical to integrate in existing buildings. Water may be used as the storage medium.
