Title: Engine mixture control system - has regulator multiplying relationship between engine parameter and exhaust gas quantity returned
Inventor: ZELLER HANS DIPL ING
IPC: F02M26/00
Filed: 1975-07-01
Abstract: The system alters the mixture delivered to an internal-combustion engine, exhaust gas being returned to the intake.

Title: Anti jackknife control for articulated bus - has sensor controlled latches to limit angle of trailer without locking joint completely
Inventor: SCHULTZ OTTO WILHELM OSWALD
IPC: B62D47/02
Filed: 1976-02-20
Abstract: The articulated bus has two anti-jackknife locks (A, B) which act separately to limit the angular displacement of the trailer but which allow the trailer to swing back into line, without locking the joint completely. This provides improved steering control especially with the drive unit in the trailer. An optic or mechanical sensor on the trailer monitors the angular displacement and a control compares the displacement with the front wheel lock. If there is a discrepancy between the settings, with a max. limit on the trailer displacement, then the lock operates on the appropriate side of the coupling.

Title: Remote control system preventing information loss - uses control centre to acknowledge correct receipt of outstation data
Inventor: BIZER WERNER DIPL ING
IPC: H04L1/18
Filed: 1976-04-07
Abstract: The information loss in a remote control system is prevented by transmission of the information from the outstations to the control centre as continuous addressed block-blocks. The control centre then acknowledges the correct receipt of information blocks by transmitting their addresses back to the outstanding asynchronously. The information blocks, for which no address is transmitted back as acknowledgment of correct receipt, are repeated once or several times by the outstation concerned. The acknowledgement telegram is transmitted back at an arbitrarily chosen later thime and is asynchronous relative to the information blocks. High priority acknowledgement is provided for high priority instructions.

Inventor: WIESINGER JOHANNES PROF DR ING
IPC: H01T4/10
Filed: 1976-06-19
Abstract: The spark gap is provided for limiting overvoltages in low-voltage installations and for lightning-protection coupling of DC-decoupled circuits.

Title: Tape reel speed control circuit in tape recorder - has reversible counter operated by sensors monitoring tape loop position
Inventor: MEYER FRANZ-JOSEF
IPC: G11B15/58
Filed: 1976-09-28
Abstract: The tape recorder is used in data processing equipment. It has a driving motor for each reel. There is a tachogenerator coupled with the motor shaft, and a control amplifier which delivers a control signal to the motor, derived from the tachogenerator voltage proportional to the reel actual speed, and a reference element voltage proportional to the nominal speed.
