Title: Vacuum servo for hydraulic brakes - with pressure control valve for fail safe manual overide if servo fails
Inventor: BELART JUAN
IPC: B60T13/565
Filed: 1975-05-14
Abstract: The vacuum operated brake servo has the vacuum servo cylinder between the input hydraulic cylinder and the master brake cylinder with the input cylinder having a larger dia. than the master brake cylinder in order to generate a mechanical advantage. If the servo pressure fails then the input piston operates directly on the servo linkage and thereby on the master cylinder piston, while a control valve vents the excess fluid into a reservoir in order to reduce the mechanical advantage to unity. The loss of servo pressure therefore does not affect the brake pedal stroke.

Title: Diesel engine speed governor - uses spring loaded eccentric mass to release engine stop
Inventor: HEYER EBERHARD DIPL ING
IPC: G05D13/04
Filed: 1975-07-28
Abstract: The release mechanism consists of a fly wheel ring (1) with an eccentric mass distribution held centrally by a spring (2) under normal working conditions. On reaching a predetermined excess engine revolution speed, the fly wheel ring takes up an eccentric position owing to centrifugal force and causes a push rod (3) to pivot an angle bracket and pull a wire. The wire then draws a bolt from a spring loaded pawl whose free end puses the control bar towards the engine stop position. The pawl has a profile which moves the push rod (3) further back into the release position and the pull wire is slackened so that the push rod is no longer in contact with the eccentric.
