Title: Electronic control system for track signalling - uses cyclic interrogation of track section and command registers
Inventor: ZILLMER ADALBERT DIPL ING
IPC: B61L19/06
Filed: 1976-08-23
Abstract: The electronic control system for railway tracks using a central data processor, is based on cyclic interrogation of each track section to determine whether the command signal has been executed. The comman signals are transmitted in several successive stages. First, an interrogation is made of all track sections which are to be included in the route being set up and subsequently, a check made between the required status of the section and its actual situation. Commands are stored in a signal register according to the type, track code, start signal, destination and overrun length. The command register and a store which holds the tract section status data are strobed by a cyclic selector so that when one section has been established, the selector searches for the next entered in the command register.

Title: Rotary electric machine with reduced armature reaction - has pole laminations interleaved with non-magnetic material for flux to encounter high magnetic reluctance
Inventor: BHONGBHIBHAT WISNU DIPL ING
IPC: H02K1/24
Filed: 1977-10-10
Abstract: The rotary electric machine includes laminations in the poles and yokes associated with the energising windings. The laminations are arranged to be parallel to the axis of rotation and are interleaved with non-magnetic or poorly magnetic material. Thus in order to reduce armature reaction the laminations are so arranged that the magnetic flux which is provided by armature current flow encounters a high magnetic reluctance. Armature reaction may be further reduced by leaving a space between adjacent halves of the poles. This construction is also applicable to machines with commutating poles.
