TL;DR: The United States Demonstration Poloidal Coil (US-DPC) as discussed by the authors was designed for 10-T operation with charging and discharging from zero to full field at ramp rates of up to 10 T/s.
Abstract: The United States Demonstration Poloidal Coil (US-DPC) has been built and will be tested at the Japan Atomic Energy Research Institute (JAERI). The 2-m-diameter, 30-kA, Nb/sub 3/Sn solenoid is designed for 10-T operation with charging and discharging from zero to full field at ramp rates of up to 10 T/s. The fabrication is described. A summary of problems encountered in the manufacture of the wind-react-insulate coil made from cable-in-conduit conductor (CICC) is given.

TL;DR: In this article, an improved motor vehicle transmission locking device for use with automatic transmissions and manual transmissions is presented. But the solenoid is mounted inside of the transmission case and may also be activated by a simple switch or lock switch hidden out of sight on the motor vehicle, which can be used to lock into a notch formed on an existing transmission parking shaft to lock the transmission in the parked position.
Abstract: An improved motor vehicle transmission locking device for use with automatic transmissions and manual transmissions. The improved locking device utilizes a solenoid which is used to lock into a notch formed on an existing transmission parking shaft to lock the transmission in the parked position. The solenoid is mounted inside of the transmission case and may be activated by an encoder/decoder circuit and may also be activated by a simple switch or lock switch hidden out of sight on the motor vehicle. A modified form of the invention replaces the existing transmission parking shaft with a split shaft and positions the solenoid between the two pieces of the split shaft. This modification then accomplishes the enabling and disabling of the transmission when activated by either the encoder/decoder circuit or by other switching circuits positioned on, and hidden from a thief that may try to steal the motor vehicle.

TL;DR: This work presents a survey of the major systems required for such unconfined magnetic field design, allowing the identification of key technologies for future development.
Abstract: Many active magnetic shielding designs have been proposed in order to reduce the radiation exposure received by astronauts on long duration, deep space missions. While these designs are promising, they pose significant engineering challenges. This work presents a survey of the major systems required for such unconfined magnetic field design, allowing the identification of key technologies for future development. Basic mass calculations are developed for each system and are used to determine the resulting galactic cosmic radiation exposure for a generic solenoid design, using a range of magnetic field strength and thickness values, allowing some of the basic characteristics of such a design to be observed. This study focuses on a solenoid shaped, active magnetic shield design; however, many of the principles discussed are applicable regardless of the exact design configuration, particularly the key technologies cited.

06 Aug 1984TL;DR: In this article, an electromagnetic unit fuel injector includes a pump assembly having an external actuated plunger reciprocable in a bushing with flow therefrom during a pump stroke being directed to a fuel injection nozzle of the assembly.
Abstract: An electromagnetic unit fuel injector includes a pump assembly having an external actuated plunger reciprocable in a bushing with flow therefrom during a pump stroke being directed to a fuel injection nozzle of the assembly. Fuel flow from the pump can also flow through a passage means, containing a normally open, substantially pressure-balanced control valve actuated by a solenoid assembly in the valve closing direction to block drain flow during a pump stroke, as desired. A piston, actuated by discharge fuel pressure is operatively connected to the control valve to assist the solenoid in holding the control valve in a closed position.

21 Jan 1988TL;DR: In this paper, a fluid pressure braking system includes pressure sensors in each of the supply and service reservoirs and in the supply line to the trailer, and an air compressor which is loaded and unloaded by actuation of a solenoid valve by an electronic control module which is responsive to the pressure sensors.
Abstract: A fluid pressure braking system includes pressure sensors in each of the supply and service reservoirs and in the supply line to the trailer. The system includes an air compressor which is loaded and unloaded in response to variations in the pressure level in the supply reservoir by actuation of a solenoid valve by an electronic control module which is responsive to the pressure sensors. The system includes spring brakes which are controlled by the control module through actuation of solenoid valves. The control module is similarly responsive to supply line pressure and the pressure level in the supply line to control a solenoid valve which controls communication through the supply line.
