Title: Pneumatic brakes for trailer - has fail safe interlock to isolate and vent trailer brakes in emergency
IPC: B60T15/36
Filed: 1975-10-21
Abstract: The trailer pneumatic brakes are coupled to the towing unit brakes by a control valve which provides sufficient pressure to hold off the emergency brakes on the trailer. In the event of a defect in the trailer brakes a pressure sensing valve in the connecting line senses the pressure difference of the trailer and towing unit systems and above a set threshold it isolates the trailer brakes and vents them to atmosphere. This enables the emergency brakes to operate with a minimum of delay. Operating the towing unit emergency brakes results in sudden pressure rise which has the same effect on the trailer brake control valve.

Title: Electronic seven segment display with checking system - uses seven double segments with parallel drive converters connected to comparator
Inventor: BERG WALTER
IPC: G09G3/04
Filed: 1976-01-19
Abstract: A seven segment numerical display, suitable for liquid crystal elements, is designed to provide some indication of erroneous display conditions. Each segment (2) of the display element is composed of two elements side-by-side. Seven bit words for driving the display are generated by two BLO/7 segment code converters. Identical bit positions from each of the converters are coupled to a pair of display elementS. Inputs to the converters are provided by a 5 bit shift register, with the fifth bit being an odd parity checking bit. The system is completed by seven-two bit comparators coupled to each bit position of the converter output. A check on a individual comparator output as compared with the actual display enables the source of error to be located.
