A system for moving a portion of a patient's body including a housing having a first cavity extending along a longitudinal axis, a first distraction rod having a proximal end and a distal end, the first distraction rod and the housing being telescopically displaceable with respect to each other along the longitudinal axis, the first distraction rod having a cavity extending along the longitudinal axis, a second distraction rod having a proximal end and a distal end and configured to be telescopically displaceable from within the second cavity along the longitudinal axis, and a drive system configured to move the first distraction rod in relation to the housing and to move the second distraction rod in relation to the first distraction rod.

The Seat Base Motion Controller provides automated control of seat motion for seat systems employed in providing combined visual and motion experience for patrons in amusement rides and the like. Occupant safety features are integrated within the seat motion control system and centralized control of multiple motion bases is accomplished. Motion control of the seat bases is responsive to a position signal input coordinated with a visual presentation viewed by the patrons. Self contained power systems for the actuation means of the seat base allows sizing of an entertainment threater to accommodate anticipated audiences. Independent control and operation of each motion base precludes the need for shutting down the entire theater if a fault exists in one motion base or the safety systems on that motion base are activated.

A fluid dispensing method and apparatus particularly adapted for post-mix dispensing of a soft drink, with accurate relative proportions of carbonated water and soft drink syrup. Separate syrup and water valves are controllably turned on and off, independently, at prescribed duty cycles, to provide a prescribed mix ratio, and syrup and water flow meters monitor the instantaneous flow rates of the water and syrup to minimize the effects of any pressure variations in the initial syrup and water supplies. The apparatus is conveniently modified for use with different soft drink syrups using a separate removable personality module for each syrup, characterizing its prescribed mix ratio and its viscosity.

Fluid dispensing system

A post mix dispensing system for mixing together and dispensing carbonated water and a flavored soft drink syrup, while generating substantially reduced amounts of foam. Carbonated water is injected into a special staging chamber, where it circulates turbulently at about atmospheric pressure. The water is ported from the chamber through a plurality of elongated ports, substantially under gravitational forces alone, and the ports are configured to straighten the flow of water and remove most of its kinetic energy. A nozzle deflects the water to converge upon a stream of syrup and to mix with the syrup in an unconfined region, after a substantial proportion of the gases released from the water has escaped, thereby substantially reducing the generation of foam.

Post mix dispensing method and apparatus

A fluid flow meter having a paddle wheel rotatably mounted in a cylindrical cavity and an inlet conduit and an outlet conduit tangentially aligned with the periphery of the cavity for directing a fluid to flow through it. The paddle wheel's axis of rotation is displaced from the cavity's centerline, in the direction of the inlet conduit and substantially perpendicular to the flow of fluid entering the cavity, such that the flow meter operates effectively over an extended range of Reynolds numbers, spanning both turbulent and laminar flows.
