摘要： Natural gas is stored in a closed vessel under a pressure of about 1400 to 4500 kPa using a carbon molecular sieve adsorbent. The deliverable volume of natural gas from a vessel packed with carbon molecular sieve particles is increased by impregnating a polymer precursor of the carbon molecular sieve with additional monomers and polymerizing the monomers before carbonizing the precursor.

摘要： A speed adjuster is provided in a belt-disc sander for controlling the rotating speed of a motor of the belt-disc sander. A speed adjust knob is disposed outside the belt-disc sander. The speed adjuster has a control circuit, a current sensor, a drive circuit, and a converter. The current sensor detects the motor current and feeds back to the control circuit, which controls the frequency variation of a SPWM signal of the drive circuit in response to the input of the speed adjust knob. The converter transforms the square wave voltage into an AC voltage for driving the motor. The desired rotating speed can be adjusted through the speed adjust knob. The control circuit will compare the present rotating speed of the motor with the set rotating speed to determine whether the present rotating speed conforms to the set one for correcting the rotating speed of the motor.

摘要： A process for separating isoprene from isobutylene, isopentane, and pentene-1. The process uses an adsorbent comprising activated carbon or molecular sieve carbon to selectively adsorb isoprene from the other hydrocarbons. High purity isoprene is recovered by desorption using desorbent materials which include olefinic hydrocarbons. The process is particularly suited for a simulated moving bed apparatus.

摘要： An electronic ballast system with emergency lighting features is presented. Especially, the electronic ballast system is relative to a single-stage converter configuration. The electronic ballast system serves as a regular ballast, a regular/emergency ballast, a battery charger or discharger and a power failure detector, fulfilling emergency lighting features. The single-stage converter used in the ballast is an integration of a bi-directional flyback converter and two half-bridge series-resonant parallel-loaded inverters. Unlike conventional approaches, the rectified and filtered input voltage is directly added to a set of battery voltages in the proposed system, so as to reduce the fabrication cost by simplifying the circuit configuration and the number of active switching elements.
