摘要:
In a satellite control system, a liquid is ejected by thermal ejection from holes in a substrate structure to create a reactive force on the satellite allowing the position, such as the attitude, of the satellite to be adjusted.

摘要:
Provided is a method for operating a gas-phase, fluidized-bed reactor. The method has the steps of (a) receiving a signal from a probe in contact with the interior of the reactor or a process component in communication with the reactor, wherein the signal is derived from a physical property or condition within the reactor or the process component; (b) modifying the signal to create a modified signal; and (c) adjusting one or more operating parameters of the reactor in response to the modified signal if the physical property or condition is different than a desired value. There is also a method for reducing fouling in a distributor plate of a gas-phase, fluidized-bed reactor with a recycle line.
摘要:
The invention includes a dust mitigation device that utilizes electromagnetic waves to protect devices from dust deposition. The device includes a nonconducting (dielectric) material separating at least one electrode, and in some embodiments a plurality of electrodes, from a grounded layer. The electrodes are connected to a single phase AC signal or a transient voltage signal. In some embodiments the grounded layer is created using a continuous conductor or a conductive grid. In some embodiments, the dielectric, the electrodes, and/or the grounded layer are transparent. The electromagnetic fields produced by the electrodes lift dust particles away from the shield and repel charged particles. Deposited dust particles are removed from the dust mitigation device when the electrodes are activated, regardless of the resistivity of the dust. The invention further includes a method of mitigating dust using such components.
