Title: Vehicle location monitoring system - has range and travel direction sensors to provide signal for memory
Inventor: HENSON ALFRED J
IPC: G01C21/26
Filed: 1973-08-14
Abstract: The pulses of travelled distance sensor are counted down by a divider connected to a counter while the transducer sensing the direction of motion and the keyboard combine with a sensor to feed a multiplexer. The keyboard is connected to a coding matrix and the multiplexer is controlled by pulses from a line. The h.f. carrier of the transmitter is modulated by the train pulses with its output feeding aerial. The memory stores the coordinates of the last known vehicle location which are then replaced by the new date of the second memory. The contents of the two memories are compared by a discriminator for updating the first memory.
Patent DE-2341672-A1 (DE)
Title: Anti-blocking brake with fail safe facility - which moves control piston to safety bypass setting on servo failure
Inventor: MAYER FRIEDRICH
IPC: B60T8/94
Filed: 1973-08-17
Abstract: The brake control valve has a piston which is held in a normal braking position by the combined action of the spring and the brake pressure. When the wheel sensors detect wheel lock, a servo force acts on the other side of the piston and moves it into a blocking position, while an expansion chamber reduces the wheel brake pressure. To cater for servo failure such as when the servo control valve sticks, and servo force cannot be reduced, a safety control, with electric contacts to hold the piston in the second position, is activated to enable the piston to move into a third position where the fluid flow through the valve is re-established.

Title: Controlled braking of audio recorder tape drive mechanism - involves counter dials set to actuate contact when pre-arranged sequence occurs
Inventor: HERLETH KARL
IPC: G11B15/22
Filed: 1973-08-21
Abstract: The arrangement for braking the drive mechanism for the tape spools of an audio recorder, particularly a casette machine, comrises an advance contact. This contact is actuated when projections on the tens, hundreds and thousands counter dials of the tap movement counters, which are arranged on one shaft connected to the tape drive mechanism, contact projections on a connected key. Actuation of the advance contact leads to the electric motors being braked by disconnection of the electric current. The projections for the advance contact are pref. of a different form from those which stop the drive mechanism through a similar contact, these being pref. detents in the opposite edges of the dials to those with the projections.

Title: Telephone exchange with a switching network - has input and output terminals connected to row wires arranged in groups
Inventor: HAFERKAMP VOLKER
IPC: H04Q3/00
Filed: 1973-08-28
Abstract: The row wires can be connected through switching points to column wires divided in different stages. Junction wires are connected to the switching network terminals and arranged in bunches, from which a free wire is selected in connection with route search. Column wires are also arranged in groups. Wires in the lowest group can be connected with row wires in one group only. Column wires in a second and further groups can be connected to row wires in two or more groups, while the wires in the highest group can be connected to row wires in all groups. When a bunch of junction wires is selected, a free wire is chosen, which lies if possible in the same group of row wires as that connected to the incoming terminal, and can be reached through a free column wire of the lowest possible group. The selector always operate in a fixed scanning order, but start from an initial position determined by the incoming engagement.
