Abstract: Apparatus and method in which a solid or liquid additive is dispensed within a mixing chamber for mixing with a fluid from the pressurized fluid flow line and is effective mixed in a vortex under vacuum while precluding contamination of the unused additive.

Abstract: An apparatus for moving parked aircraft with a tractor via an aircraft lift dolly which includes a hinged gate to entrap the aircraft nose gear. The aircraft lift dolly may be removably detachably coupled to the tractor through two attachment points to an intermediate connecting towbar. The aircraft lift dolly includes a lift mechanism having a lift carriage which is selectively elevated. The lift carriage includes a fixed forward chock and a rear chock that it repositioned longitudinally with respect to the forward chock and is hingedly coupled. The chocks are positioned about the aircraft nose gear without movement of the aircraft. Elevating the lift cradle elevates the chocks and the nose gear cradled therebetween.

Abstract: A system for delivering an additive to a flowing fluid wherein the system is in whole or in part powered by the flow of the fluid is provided. The fluid-additive delivery system includes a fluid motor, a speed sensor, an electricity generation and storage system, a clutch, an additive pump, and a flow meter, where the fluid motor and the flow meter are in fluid communication with a piping of the fluid to which the fluid additive is to be added. Preferably, the fluid is a fuel and the fluid additive to be added is a fuel additive.

Abstract: An apparatus for moving parked aircraft with an omni-directional tractor via an aircraft lift dolly that is revolvably coupled thereto which includes a hinged gate to entrap the aircraft nose gear. The aircraft lift dolly may be removably detachably coupled to the omni-directional tractor or may be integral to it through two attachment points via attachment members.

The lift carriage includes a fixed forward chock and a rear chock that it repositioned longitudinally with respect to the forward chock and is hingedly coupled. The chocks are positioned about the aircraft nose gear without movement of the aircraft. Elevating the lift cradle elevates the chocks and the nose gear cradled therebetween.

Abstract: System for determining the flow rate of a fluid and for controlling flow rates. The system provides high resolution with infinite turndown, providing a flow meter which may be used in low flow situations and with fluid additives. The flow rate of an additive fluid is determined in real time with high resolution by providing a novel reciprocating positive-displacement flow meter using magnetically coupled components and a transducer to identify the flow rate of the fluid. A system and method may be incorporated into a flow control system for monitoring the flow rate of a fluid which may be included with an additive delivery system for use with the flowing supply of an additive to be introduced into a flow of untreated fluid in relatively minute quantities.

Abstract: A liquid metering device that dispenses liquid into an adjacent reservoir at a precise ratio relative to the total volume of the adjacent reservoir as the reservoir is filled with liquid. The hydrostatic dispensing system includes an additive reservoir, a calibrated dispensing vessel, a hydrostatic pressure chamber, a pressure limiter, and a three-way valve that passively arms and dis-arms the system.

Abstract: A liquid metering device that dispenses liquid into an adjacent reservoir at a precise ratio relative to the total volume of the adjacent reservoir as the reservoir is filled with liquid. The hydrostatic dispensing system includes an additive reservoir, a calibrated dispensing vessel, a hydrostatic pressure chamber, and a three-way valve that passively arms and dis-arms the system. The precise dispensing of liquid by a calibrated dispensing vessel into the adjacent reservoir is accomplished entirely through the management and arrangement of hydrostatic pressure creating a liquid piston generated by the addition of liquid to the adjacent reservoir and its subsequent application to the liquid in the calibrated vertical column that displaces the calibrated volume of liquid into the reservoir at the same rate that liquid is added to the reservoir.

Abstract: An omni-directional vehicle (ODV) with a circular frame revolvably coupled to an appendage ring using a full circumferential coupling assembly. The appendage ring serves as a point of attachment for a push bar, trailer, tool, vehicle chassis, or other device. Two independent drive wheels located on an axis through the center of the frame are mounted at the same distance from a central vertical axis through the frame. Each wheel is powered independently and can rotate at variable speeds in either direction. The ODV is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The ODV can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground.

Abstract: A vehicle with a omni-directional cab having a circular frame revolvably coupled to a chassis having an axle, wheels and passenger seats. Two independent drive wheels located on an axis through the center of the cab are mounted at the same distance from a central vertical axis through the cab. Each wheel is powered independently and can rotate at variable speeds in either direction. The cab is capable of movement in any direction by rotating the axis of the drive wheels to a position which is perpendicular to the desired direction of travel. The cab can spin about its vertical axis such that the axis of the drive wheels can be oriented at any direction without changing the original footprint of the space that the frame occupies over the ground. Thus, the combined cab/chassis assembly can rotate about the vertical midpoint of the chassis axle.
