Title: Electric generator without external mechanical energy source - uses conventional generator and electric unit carrying field magnets and armature
Inventor: MUKHERJEE CHITTA RANJAN
IPC: H02K53/00
Filed: 1977-07-26
Abstract: The magnetic to electrical energy conversion machine, e.g. generator, is designed such that, unlike conventional generators requiring an external source of mechanical energy to be input into the generator before electrical energy can be generated, no energy is required from any external source other than from the generator itself in order to generate electrical energy. Thus, the invention comprises a conventional electrical generator and an electrical unit fitted with excitation (field) magnets and an armature containing conductors that carry the electrical current opposing the counter force generated at the conventional generator shaft, to generate the drive force required to rotate the generator shaft. The electrical unit is mounted on the generator shaft and rotates together with the shaft and continuously exerts the drive force onto the shaft.

Title: Telephone exchange signalling system - has code verifier to ensure only correct and full codes are fed to common control
Inventor: POLLACK WOLFGANG
IPC: H04Q3/42
Filed: 1978-12-21
Abstract: All aborted calls, and those of incomplete structure or information are not routed into the common control so that the latter only has genuine routings for useful traffic to handle, thus effecting savings in equipment cost. All incoming information from junctions, or dialled by local subscribers, is routed via a code verifier which aborts the attempt if the information is incomplete and thereby protects the common control from having to attempt to set up a call which cannont be completed. The code verifier also has a delay facility to hold information in cases where the common control is heavily loaded and there is a delay before the call can be routed. Local subscribers are connected to the code verifier through the switch block and a local relay set. A direct highway exists for the incoming junctions.
