Abstract: A system for continuously processing a combination of materials includes a continuous process vessel having an outlet and one or more inlets. The continuous process vessel is configured to oscillate along an oscillation axis. An acoustic agitator is coupled to the continuous process vessel. The acoustic agitator is configured to oscillate the continuous process vessel along the oscillation axis. An outlet passage is in fluid communication with the outlet. At least a portion of the outlet passage or at least a portion of the continuous process vessel is disposed within a portion of the acoustic agitator.

Abstract: Provided herein are resonance-enabled machines, comprising one or more voice coil actuators mounted on a non-moving mass, such as a housing, one or more moving masses, and one or more pluralities of springs coupling the non-moving mass to the one or more moving masses. One or more of the moving masses can perform a specific task. For example, the moving mass may drive a pump as a vacuum pump or a compressor. The moving mass may drive a hammer chisel, for example, to break or fracture structures. The moving mass may drive a device to consolidate, for example, soil. The moving mass may impact a member to drive the member into another member, such as a pile into the soil. Each moving mass may be coupled to a voice coil actuator, and the machine is an electrical-mechanical-electrical transformer.

Abstract: The present disclosure provides a blended powder comprising a first ferroalloy powder and at least one iron powder or second ferroalloy powder. The present disclosure also provides a method for dry metal alloying, comprising combining powder comprising a first ferroalloy powder and at least one iron powder or second ferroalloy powder, and mixing the combined powders to form a blended powder.

Abstract: Provided herein is a mechanical resonant system, comprising a frame; at least one pump disposed on the frame; one or two masses coupled to the frame by a first plurality of resilient members; and at least one voice coil actuator disposed within the frame and coupled to the at least one pump or to the one or two masses; wherein when the system comprises two masses, a second plurality of resilient members couple the masses to each other. Also provided are methods for using these mechanical resonant systems to evacuate a chamber, to compress air, or sense changes in pressure.

Abstract: Provided herein is a resonance-enabled drill, comprising a housing; one or more force generators chosen from one or more voice coil actuators, one or more eccentrics driven by one or more electric motors, or combinations thereof; one or more sonic heads coupled to the one or more force generators; a plurality of springs coupling the housing to the one or more sonic heads; and a drill rod disposed on its proximal end to the one or more sonic heads. Also provided is a gauge for a sonic drill configured to display information to an operator, for example indicating to the operator when the drill is on or near resonance. Further provided are methods for selecting a resonance frequency in a sonic drill.
