Title: Linear motor for driving model magnetically suspended trains - has moving primary winding and no sliding contacts
Inventor: ZIRKEL FRANK UWE
IPC: H02K41/02
Filed: 1973-07-03
Abstract: The object is to provide control of model speed, for example a toy railway with magnetic suspension, without the complication of either a continuous primary winding along the whole of the track or sliding power and control contacts between track and vehicle. The problem is resolved by beaming in both energy and control signals from selected points along the track. Electromagnetic radiation is typically employed, for example in the higher megahertz bands, and use may also be made of optical control links. The stationary parts of the motor may be made from ferro magnetic and, or permanently magnetic material, and these may also be used as the aerials.
Patent DE-2337351-A1 (DE)
Title: Spring clip assembly for installation mounting on support rails - has spring-loaded slider holding gear to rail and locked out for gear removal
Inventor: BAUER JOHANN
IPC: H02B1/052
Filed: 1973-07-23
Abstract: The mounting assembly fro clipping electric installation gear or components onto support rails has a spring-loaded slider whose inner end is forced by a spring underneath and against the support rail, thus holding the gear to the rail. The gear is removed from the rail by pulling out the slider. This releases a blocking arm whose spring flap tilts it down to prevent the slider from returning to its locked position. The gear can then be removed from the rail. To remount the gear it is simply placed over the rail which forces up the blocking arm by acting on a downward pointing projection which releases the slider. The slider end once again locates against and under the support rail.
