Title: Multi-phase electric machine mfr. - has soft T-section magnetic segments, arrow or gearwheel shape which are inserted radially into prefabricated self-supporting conductor structure.
Inventor: HILL WOLFGANG
IPC: H02K15/02
Filed: 1992-10-09
Abstract: The method involves forming overlapping conductor strands by radial insertion of soft magnetic segments into a prefabricated self-supporting flexible multiphase winding. The coils of wire and encapsulating resin are impregnated and subjected to compression and tension before the resin is hardened. Shaped coils and rod windings are axially butted together after welding or soldering, making for very compact windings with short connection paths in the winding heads. The soft magnetic segments are inserted radially without deformation. An axially fitted supporting ring guarantees tight assembly without bonding. ADVANTAGE - Magnetic strips or sheets are used effectively even for annular components. Joints can be fusion-bonded without damage to insulation of adjoining conductors.

Title: Time-code radio receiver synchronised clock
IPC: H04B1/28
Filed: 1993-12-01
Abstract: The radio receiver has an antenna oscillator circuit (A) inputting signals to the terminal (1) and an input amplifier with AGC. The signal is mixed with the 32768 Hz signal of the clock quartz oscillator (8) and amplified in the IF strip using two piezo-resonators of 110.268 kHz. The signal is then passed to a full-wave rectifier, demodulator and Schmitt trigger to generate a time code signal (G). The IF signal is generated using the clock oscillator to generate a sum mixer frequency. The piezo-resonator frequency is the sum of the input frequency and a multiple of the oscillator frequency.
