Publication number: 20210154799Abstract: An abrasive suspension jet cutting system, the system includes a cutting head. The cutting head has a feed assembly, nozzle and acceleration cavity therebetween. The feed assembly has a slurry orifice and a shielding fluid orifice. Within the acceleration cavity abrasive slurry and shielding fluid are accelerated together from the slurry orifice to the nozzle while maintaining a shielding fluid barrier substantially unmixed with the abrasive slurry around the abrasive slurry. The cutting head is further configured to have both the slurry and shielding fluid pass substantially unmixed through the nozzle thereby limiting nozzle wear. A wear control system is provided to reduce wear of the nozzle and other system components during start and stop. The system may further include a reclamation system that collects and reclaims used abrasive particles and fluid and returns them back to the cutting head to be reused thereby reducing system operational costs.Type: ApplicationFiled: November 23, 2020Publication date: May 27, 2021Applicant: Synticos, LLCInventors: Robert C. Dean, JR., Erik Keith Johnson, Alex David Perkins, Read Ferguson Frost

Patent number: 8025371Abstract: A device, method and system for causing a controlled collapse of cavities formed within liquid droplets wherein a pressurized jet comprising a liquid and nanoparticle material produces droplets from the breakup of the jet stream. The liquid droplets may be irradiated with energy to produce and expand cavities formed within the droplets by irradiation of the nanoparticles contained within the droplets or alternatively, a volatile fluid with or without a metal nanoparticle may form the cavity. The droplets are collided with a target to collapse the cavities within the droplets. The irradiating (if provided) and colliding are timed to enhance implosion energy resulting from the cavities' collapse. The implosion energy and the fuel in the cavity may be used to activate and sustain a fusion reaction or from any other purposes.Type: GrantFiled: November 3, 2008Date of Patent: September 27, 2011Assignee: Synergy Innovations, Inc.Inventors: Robert C. Dean, Jr., R. Glynn Holt, Ronald A. Roy

Patent number: 6667459Abstract: A configurable baffle to configure fluid flow through a nozzle. To improve the quality and accuracy of processing apparatus used in the cutting, welding, and heat treating of materials, a self-aligning nozzle includes a configurable baffle. This configurable baffle can be a metallic grid (e.g., a screen) or other type of membrane (e.g., porous, permeable, etc.). During its initial use in the processing apparatus, this configurable baffle is tailored with an energy beam, such as a laser beam or plasma jet, to create an optimal fluid flow velocity profile. When the configurable baffle deteriorates from use, it is easily replaced by another baffle or by using an in situ replacement mechanism. To ensure proper alignment between the nozzle and the energy beam, mating contoured surfaces are used among adjacent components. Threaded surfaces can also be employed to assist in achieving the proper coaxial alignment.Type: GrantFiled: November 21, 2000Date of Patent: December 23, 2003Assignee: Hypertherm, Inc.Inventors: Kenneth J.

Publication number: 20030155300Abstract: Disclosed are chromatography methods and matrix geometries which permit high resolution, high productivity separation of mixtures of solutes, particularly biological materials. The method involves passing fluids through specially designed chromatography matrices at high flow rates. The matrices define first and second interconnected sets of pores and a high surface area for solute interaction in fluid communication with the members of the second set of pores. The first and second sets of pores are embodied, for example, as the interstices among particles and throughpores within the particles. The pores are dimensioned such that, at achievable high fluid flow rates, convective flow occurs in both pore sets, and the convective flow rate exceeds the rate of solute diffusion in the second pore set. This approach couples convective and diffusive mass transport to and from the active surface and permits increases in fluid velocity without the normally expected bandspreading.Type: ApplicationFiled: April 12, 2002Publication date: August 21, 2003Applicant: PerSeptive Biosystems, Inc.Inventors: Noubar B.

Patent number: 6585774Abstract: A dynamic variable geometry fitting system with fluid-filled bladders and automatically regulating their volumes to provide a continuously secure fit. This system can vary volume continuously to accommodate natural variation in an amputee's residuum. It makes reliable suction retention of a prosthesis easier for the prosthetist to achieve while reducing the potential for tissue lesions. By maintaining a continuous, secure fit, the amputee's sense of confidence and willingness to use the prosthesis increases.Type: GrantFiled: April 24, 2001Date of Patent: July 1, 2003Assignee: Simbex, LLCInventors: Robert C.

Patent number: 6270445Abstract: Methods of use of a portable in-bed exercising machine are provided for strengthening and/or strength maintenance of the musculature and ligaments associated with an extremity. The exercise apparatus employs the principles of closed kinetic chain exercise of the extremity in both concentric and eccentric modes and for isometric, isotonic and isokinetic exercise. Each extremity is engaged separately allowing for bilateral, unilateral and reciprocal motion. As exemplified for lower extremities, force is actively applied to the feet with each lower extremity having the force level continuously adjustable from zero force to a force equal to or greater than body-weight The exercise motions and force applications use the same major muscle groups as functional activities such as standing from a chair, climbing stairs walling, jumping and jogging. Vertical support is provided for the lower extremity to stabilize and control the lower extremity motion within safe limits.Type: GrantFiled: September 20, 2000Date of Patent: August 7, 2001Assignee: Simbex LLCInventors: Robert C. Dean, Jr., Solomon Diamond, Elizabeth K. Deneen, Amanda G. Heermans, Gayle B. O'Neil, David S. Smith
