Improved magnetometer uses toroidal gating coil
Improved magnetometer employs a cylindrical, high permeability magnetic core with a toroidal gating coil and a solenoid pickup coil. Flux interaction can be reduced by electrostatically shielding the pickup coil from the gating coil. The magnetometer principle can be applied to navigation devices.

Device disconnects several couplings simultaneously
Actuator assembly disconnects electric cable and fluid-line coupling from a rocket. The disconnector incorporates interconnected hydraulic cylinders which effect an equal and simultaneous displacement of pistons upon admission of compressed air through a solenoid control valve.

Respiratory transfer value has fail-safe feature
Quick-acting, remote controlled valve connects either one of two oxygen or air supplies to a breathing tube. The valve, which is fall-safe, incorporates a cammed piston arrangement that is driven by a remote controlled reversible rotary solenoid or reversible electric motor.

High-pressure, low temperature electrical connector makes no-leak seal
Flow control of cryogenic liquids is achieved through use of an electrical feed-through connector with a solenoid-type valve. To prevent gas leakage, the connector is designed and structured so that extremely high pressure and low temperatures contribute to its sealing properties.

System proportions fluid-flow in response to demand signals
Control system provides proportioned fluid flow rates in response to demand signals. It compares a digital signal, representing a flow demand, with a reference signal to yield a control voltage to one or more solenoid valves connected to orifices of a predetermined size.

Separation simulator
Separation simulator, consisting of a control panel and an electromechanical simulator unit, simulates electrical separation of space flight vehicle stages. Simulation is accomplished by electrically inserting the simulator between the normal interstage couplings of the vehicle. Actual separation is accomplished by energizing two solenoids.
