Abstract: Methods, devices, and systems for treating blackwater are disclosed. A storage tank and a tumbling kiln charged with a solid media are provided. Blackwater is passed into the storage tank. The blackwater contains a liquid component and a solid component. The solid media and the tumbling kiln are heated. The blackwater is passed from the storage tank to the tumbling kiln. A portion of the liquid component is vaporized as vapor. A portion of the solid component is combusted to produce combustion gases. Fresh air is circulated into the tumbling kiln. The vapor and the combustion gases are removed from the tumbling kiln.

Abstract: The invention is a system for optimizing a trailer path and a tow vehicle path. The system includes image sensors configured to capture images of a trailer and images of a path of travel both in front of and behind the trailer and tow vehicle, a weight determination system, accelerometers that sense acceleration of the tow vehicle and/or the trailer, a data input device configured to receive input data, and a processing device. The processing device includes a processor and non-volatile memory. The processor is configured to receive image data from the image sensors, receive weight data from the weight determination system, receive accelerometer data from the one or more accelerometers and receive the input data from the data input device. Additionally, the processor is configured to determine a trailer path and a tow vehicle path based on the image data, accelerometer data, and the input data. The processor is also configured to determine a safety parameter, communicate the trailer path and tow vehicle path to a user or vehicle control system, thereby prompting adjustments to the tow vehicle path and or acceleration when the trailer path or tow vehicle path is not optimum.

Abstract: A winch is disclosed having a drive cylinder, configured to be rotated by an applied force about its longitudinal axis and having at least three drive grooves. The winch also includes an idler with a longitudinal axis spaced apart from the longitudinal axis of the drive cylinder. A line is fed onto the winch by passing it over a first of the at least three drive grooves then around the idler and then around a second of the at least three drive grooves. The line is attached to one of a fixed object or the object to be moved. The winch is attached to the other of the fixed object or the object to be moved. As the applied force is applied to the drive cylinder, the line is gripped by the at least three drive grooves and a length of the line between the fixed object and the object to be moved is shortened, whereby the object is moved.

Abstract: A device for filtering air for a user comprising a frame formed in a generally oval-shaped band, the band encircling the user's head, with an upper portion above the user's head and a lower portion proximate to and spaced apart from the user's chin, an intake aperture formed in the frame, and an intake air filter covering the intake aperture. The device includes an air mover chamber attached with an air-tight seal to an inside surface of the frame and communicating on one end with the intake air filter and communicating on another end with a filtered air supply inlet inside the device and an air mover disposed within the air mover chamber and configured to draw air through the intake air filter and push air out the filtered air supply inlet. The device also includes an exhaust aperture formed in the frame and an exhaust air filter covering the exhaust aperture. The device further includes a transparent face shield attached with an air-tight seal to a front surface of the frame, the shield providing a space for air between an inside surface of the face shield and the user's face, and a fabric component comprising a first portion that is air permeable configured to cover the frame and filters and a second portion that is air impermeable extending from a back surface of the frame to cover a remaining portion of the user's head and encircle the user's neck.

Abstract: Methods and system for treating blackwater are disclosed. A pyrolysis chamber and a condensing heat exchanger are provided. A blackwater slurry, consisting of blackwater solids, water, and volatiles, is passed into the pyrolysis chamber. The blackwater slurry is heated to produce steam, to separate at least a portion of the volatiles, and pyrolyze the blackwater solids, the separated volatiles passing out of the pyrolysis chamber. The steam and separated volatiles are cooled in a condensing heat exchanger, condensing at least a portion of the steam and at least a portion of the separated volatiles as a contaminated water stream. A water-clarifying chemical is added into the contaminated water stream that reacts with the volatiles, resulting in a treated water stream.

Abstract: A device for filtering air for a user comprising a rigid component comprising, a transparent face shield that provides a space for air between an inside surface of the face shield and the user's face, an intake port, through which intake air enters the device, an exhaust port, through which exhaust air exits the device, a fabric component affixed to the rigid component that, combined with the rigid component, covers the user's head and seals around the user's neck, an intake filter that filters intake air passing through the intake port, an exhaust filter that filters exhaust air passing through the exhaust port, and an air mover assembly mounted on the rigid component that moves intake air through the intake port and exhaust air through the exhaust port, wherein the air mover assembly is mounted on the rigid component by vibration absorbing members, to thereby reduce transmission of the vibration of the air mover assembly to the rigid member, thereby reducing noise from the air mover assembly within the device.

Abstract: A counterbalance system for an overhead door is disclosed. The system includes a torsion adjustment comprising a first portion and a second portion, the first and second portions being rotatable relative to one another in a first direction and not in a second direction opposite the first direction. The system also includes an anchor fixed to the first portion, a collar fixed to the second portion, the collar being selectively fixable to a shaft of the overhead door, and a spring coupled between the collar and the anchor. The spring supports at least a portion of the weight of the overhead door as the overhead door is raised and lowered. Rotating the first portion of the torsion calibration collar relative to the second portion of the torsion calibration collar increases torsion in the spring and therefore calibrates the spring to support a desired amount of the weight of the overhead door.

Abstract: Systems and methods for incinerating waste solids are disclosed. A fluidized bed of solid particles is provided at an elevated temperature in a reactor. The waste stream, comprising the waste solids and water, is passed onto the fluidized bed of solid particles. The fluidized bed of solid particles has a sufficiently elevated temperature to vaporize substantially all of the water into an offgas stream. The waste solids are mixed among the bed of solid particles. Sufficient heat and oxygen are provided to incinerate the waste solids.
