  • Gyroscopic vertical reference system
    Patent number: 4297905
    Abstract: A vertical gyroscopic reference system consists of a gimballed platform solid with a stator in the form of a hollow spherical chamber in which a substantially spherical gyro rotor revolves, the rotor being both driven and supported by air pressure, and having a pressure-fed hole through its spin axis which cooperates with ports in the stator to provide signals to a pair of pneumatic actuators which slave the platform to follow the gyro rotor.

  • Fuel control systems
    Patent number: 4261308
    Abstract: A fuel control system for a diesel engine comprises a fuel pump with a fuel control member and an excess fuel member. A reversible electric motor drives a rotary member which cooperates with these two members. The driver can control a switch to "stop" and "run". A heat-sensitive switch on the engine responds to "cold" or "hot". An electric circuit causes the engine when cold to start with automatic transient actuation of the excess fuel member.
