  • Patent number: 8349059
    Abstract: A number of pocketed apparatus for separating various materials are described. A pocketed cyclonic separator that includes a cyclone chamber, which includes interior chamber walls, an inlet connected to the cyclone chamber, and one or more pocket separators, located on the interior chamber walls, is described. A substance may be introduced through the inlet into the cyclone chamber so as to create a rotational force sufficient to generate a cyclone in the cyclone chamber. Forces generated by the cyclone will cause heavier material in the substance to move towards the interior chamber walls when in use. The one or more pocket separators define one or more pockets that trap heavier material in the substance when in use.

  • Patent number: 8351114
    Abstract: A system for combining multiple fiber amplifiers, or multiple fiber amplifiers. The system includes a fiber combiner with multiple cores for connecting with the multiple fiber amplifiers and for combining the beams of the fiber amplifiers into a single beam. The fiber amplifiers are aligned, tapered, and stretched. A method for combining fiber amplifiers includes emitting a beam from a tapered fiber combiner and transmitting and coupling a portion of the emitted beam back into the fiber combiner via a feedback fiber. The transmission and coupling of the feedback fiber includes mixing the feedback fiber with the output of an auxiliary laser and boosting the feedback fiber by a pre-amplifier. The feedback fiber is split into a plurality of beams by a fiber splitter. The beams are fed into an array of fiber amplifiers and combined with output of the individual fiber amplifiers to form the tapered fiber combiner.

  • Patent number: 8293120
    Abstract: A wet cyclone particle collector is disclosed. The wet cyclone particle collector includes a cyclone unit, a liquid delivery unit and a sample collection unit. The cyclone unit draws a gas sample into a cyclone chamber and creates a circular flow of the gas sample inside the cyclone chamber so that particles in the gas sample are separated from said gas sample by centrifugation force. The liquid delivery unit delivers a collection liquid into the cyclone in a non-continuous fashion. The sample collection unit harvests the collection liquid from the cyclone unit. The non-continuous delivery of the collection liquid significantly reduces consumption of collection liquid during operation of the particle collector.
