Inventor: SCHATZ PETER
IPC: B02C23/32
Filed: 1990-08-25
Abstract: The proposal is for a device for crushing and sorting loose materials consisting of a rotor (5) in a housing with a material feed device (6) above it, an air separator (7), a finished product extractor (22) and a conveyor (6) to return insufficiently crushed material to the crushing section in the form of an upwardly directed air stream.

Title: Digital signal transmission system with switchable substitute path - performs multistep switching to this path from manually switched channel or one having excessive error rate
Inventor: BAYER JOHANNES DIPL ING
IPC: H04L1/22
Filed: 1990-10-04
Abstract: Signals are transmitted normally over parallel paths (B1-Bn) between channel units (K) linked to input and output multiplex arrangements (MI1,MII1 etc.). Each path (e.g. B1) includes two line termination units (L) and one or more repeaters (R). The substitute channel (E) may be used for low-priority messages (LP) while the other channels operate normally.
