Publication number: 20150361834Abstract: The thermodynamics of an engine require that there be a source of energy (usually in the form of heat) from which energy is taken, processed to convert this heat energy into useful torque (energy) on an output shaft, and the energy returned to a lower temperature sink. The amount of useful energy that a thermodynamic engine can transfer to the process fluid from the heat source is some proportion of the difference in the energy available between the source and sink, and the efficiency of converting the process fluid energy into useful output shaft torque. This renewable energy source thermodynamic engine manipulates the process fluid temperature to lower it below ambient temperature to use ambient heat as the source, then processes the fluid to elevate the fluid above ambient temperature to us the ambient as the sink.Type: ApplicationFiled: June 13, 2014Publication date: December 17, 2015Inventor: Alan J.

Publication number: 20150297265Abstract: Fusion of spinal vertebrae requires fixation across the disk. This fixation needs to be rigid to allow the bone to grow across the region being fused. The current approach fixes this section of spine during surgery. The patient is under anesthesia and lying flat as the surgeon sets the lordosis for this region of the spine. If the lordosis is not set right the adjacent vertebrae have to adapt to correct the lordosis. This causes the fused portion of the spine to have incorrect curvature and the adjacent vertebrae to carry higher loads. Correction of this fixated section would require additional surgery. This remote operated adjustable spine device allows the lordosis of the area to be fused to be adjusted after surgery with the patient awake and in a natural standing position. The spine device also incorporates benefits for spinal sclerosis stabilization using a simpler smaller implanted device.Type: ApplicationFiled: February 18, 2015Publication date: October 22, 2015Inventor: Alan J.

Patent number: 5015933Abstract: 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.Type: GrantFiled: November 15, 1989Date of Patent: May 14, 1991Assignee: Ridewerks, Ltd.Inventors: William M. Watkins, David L. Toyne, Alan J. Arena, Larry D. Lawver, Daniel S. Birket

Patent number: 4487333Abstract: 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.Type: GrantFiled: February 26, 1982Date of Patent: December 11, 1984Assignee: Signet Scientific Co.Inventors: Edwin Pounder, Alan J. Arena, Michael Pawlowski, Adrian M. Totten

Patent number: 4445781Abstract: 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.Type: GrantFiled: February 26, 1982Date of Patent: May 1, 1984Assignee: Signet Scientific Co.Inventors: Alan J. Arena, Edwin Pounder, Michael Pawlowski, Adrian M. Totten

Patent number: 4440030Abstract: 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.Type: GrantFiled: February 26, 1982Date of Patent: April 3, 1984Assignee: Signet Scientific Co.Inventors: Edwin Pounder, Alan J. Arena, Michael Pawlowski, Adrian M. Totten
