Title: Internal calling between two phones on small PBX - operates after delay when one receiver lifted unless key pressed for outside call
Inventor: POLLET JOHAN
IPC: H04M9/00
Filed: 1979-07-13
Abstract: In a small PBX with one exchange line and two phones, either can call the other by lifting the receiver and spinning the dial. The dial pulses are detected and connect a local ringer to the other phone. To make an outside call, an earth key must be pressed before dialling. However, contact bounce on the hook switch is liable to call the other phone before the E key is pressed. This defect is avoided by introducing a time delay of 4s before ringing the other and dispensing with the need to spin the dial. This is long enough to replace the receiver if the other is found to be engaged on an outside call.

Title: Brake fluid filter valve - with push open ball valve piston for quick emergency braking action
Inventor: ENGFER ORTWIN
IPC: B60T11/18
Filed: 1979-11-24
Abstract: A filter valve, specially for use in the hydraulic braking circuits of motor vehicles, consists of a cylinder with a spring-loaded piston which is fitted with two axial bores carrying a ball valve and a filter. When the brake pedal is used in normal gentle braking, the displaced fluid passed just through the filter and is cleaned thereby. In case of emergency braking or a clogged filter, the piston is moved against the force of the spring and a push rod contacts the far end of the cylinder to lift the ball off its seat so that the fluid reaches the brake cylinder unfiltered. This ensures a quick breaking action in case of an emergency and protects the downstream circuit from impurities in the fluid.
