Publication number: 20240115292Abstract: Exemplary embodiments of apparatus and method for obtaining one or more portions of biological tissue (“micrografts”) to form grafts are provided. For example, a hollow tube can be inserted into tissue at a donor site, and a pin provided within the tube can facilitate controlled removal of the micrograft from the tube. Micrografts can be harvested and directly implanted into an overlying biocompatible matrix through coordinated motion of the tube and pin. A needle can be provided around the tube to facilitate a direct implantation of a micrograft into a remote recipient site or matrix. The exemplary apparatus can include a plurality of such tubes and pins for simultaneous harvesting and/or implanting of a plurality of micrografts. The harvested micrografts can have a small dimension, e.g., less than about 1 mm, which can promote healing of the donor site and/or viability of the harvested tissue.Type: ApplicationFiled: October 10, 2023Publication date: April 11, 2024Inventors: Richard Rox Anderson, William A.

Patent number: 9599408Abstract: An evaporator for a loop heat pipe with high input heat transfer. The heat transfer is attained by constructing a heat pipe on the loop heat pipe evaporator heat input surface. The heat pipe then distributes the heat from limited input areas over the entire surface of the loop heat pipe evaporator, and that entire evaporator surface functions as the loop heat pipe heat input area as opposed to limited smaller areas into which the heat usually enters.Type: GrantFiled: March 3, 2012Date of Patent: March 21, 2017Assignee: Advanced Cooling Technologies, Inc.Inventors: John R.

Patent number: 8388302Abstract: A turbocharger with a high pressure (HP) and low pressure (LP) stage, designed such that swirl in a conduit providing fluid communication between the LP compressor outlet and the HP compressor inlet is received by the second stage compressor counter to the direction of rotation of the second stage compressor wheel. This is achieved without requiring vanes such as inlet guide vanes, and thus is highly efficient as well as free of blockage and excitation.Type: GrantFiled: August 31, 2009Date of Patent: March 5, 2013Assignee: BorgWarner Inc.Inventors: William G.

Patent number: 7748436Abstract: The apparatus is a capillary loop evaporator in which the vapor space is the internal volume of a cup shaped evaporator wick with sidewalls in full contact with the outer casing of the evaporator. Liquid is furnished to the wick through thicker wick wall sections, slabs protruding from the liquid-vapor barrier wick, eccentric wick cross sections, or tunnel arteries. The tunnel arteries can also be formed within heat flow reducing ridges protruding into the vapor space. The tunnel arteries can be fed liquid by bayonet tubes or cable arteries, and can be isolated from the heat source with regions of finer wick to impede vapor flow into the liquid. Tunnel arteries also enable separation of the evaporator and the reservoir for thermal isolation and structural flexibility. A wick within the reservoir aids collection of liquid in low gravity applications.Type: GrantFiled: May 3, 2006Date of Patent: July 6, 2010Assignee: Advanced Cooling Technologies, IncInventors: William G. Anderson, David Sarraf, Peter M. Dussinger, John R. Hartenstine

Patent number: 6948556Abstract: A heat transfer loop system includes a primary passive two-phase flow segment with an evaporator, a condenser and a liquid reservoir, and a secondary actively pumped liquid flow segment in which the liquid in the reservoir is drawn by a liquid pump into the evaporator, where a portion of the liquid is vaporized by the heat input and moves into the primary segment while the excess liquid is pumped back to the reservoir. The evaporator consists of a porous wick and one or more liquid arteries encased in the porous wick. The liquid arteries have porous walls to allow liquid phase working fluid to flow into the surrounding porous wick. The liquid arteries have porous walls to allow liquid phase working fluid to flow into the surrounding porous wick. The excess liquid continues to move through the arteries and eventually out of the evaporator and into the reservoir. The porous wick provides sufficient capillary force to separate the liquid inside the arteries and the vapor in the evaporator.Type: GrantFiled: November 12, 2003Date of Patent: September 27, 2005Inventors: William G. Anderson, G. Yale Eastman, David B. Sarraf, Jon Zuo

Patent number: 5975841Abstract: The apparatus is a heat pipe with an internal, multiple chamber evaporator for cooling a turbine engine stator vane. The evaporator comprises leading edge, middle, and trailing edge chambers within the stator vane, with the chambers defined by structural support ribs. Each chamber is constructed with a continuous fine pore metal powder wick coating the internal surfaces of the chamber and enclosing the chamber's central vapor space, except the wick at the very trailing edge of the vane is formed by screen embedded in the adjacent powder wick. The evaporator chambers have capillary arteries which extend through the adiabatic section of the heat pipe and terminate in a condenser wick within a heat sink structure exposed to cooler air. A capillary artery also interconnects the wick of the trailing edge chamber to the wick of the middle chamber.Type: GrantFiled: October 3, 1997Date of Patent: November 2, 1999Assignee: Thermal Corp.Inventors: James E.

Patent number: 5566751Abstract: The apparatus is a non-condensible gas venting device for vapor sources which can include a sonic orifice for vapor pressure reduction in high vapor pressure systems. A typical vapor source has a evaporator chamber with an evaporating wick containing liquid which is heated and produces vapor. The invention is a venting chamber connected to the evaporator chamber so that the vapor has access to the venting chamber. The venting chamber also includes a condensing wick interconnected to the evaporating wick in the evaporator chamber by a capillary capillary device through which the condensed liquid is returned to the evaporating wick. The condenser chamber is vented to a lower pressure region or vacuum so that non-condensible gas present moves out of the condenser chamber into the lower pressure while the vapor is trapped by the condensing wick and is retained in the system.Type: GrantFiled: May 22, 1995Date of Patent: October 22, 1996Assignee: Thermacore, Inc.Inventors: William G. Anderson, Kevin H. Richardson, Scott D. Garner

Patent number: 5492570Abstract: The apparatus is a combined Alkali Metal Thermal to Electric Converter (AMTEC) and a thermionic energy converter which are mated by the use of a common heat transfer device which can be a heat pipe, pumped fluid or a simple heat conduction path. By adjusting the heat output surface area of the thermionic converter and the heat input surface area of the AMTEC, the heat transfer device accomplishes not only the transfer of heat from the output of the thermionic converter to the input of the AMTEC, but also the transformation of the heat density to match the requirements of the AMTEC input. The electrical current through the combined devices is also matched by adjusting the heated surface area of the AMTEC.Type: GrantFiled: July 5, 1994Date of Patent: February 20, 1996Assignee: Thermacore, Inc.Inventors: Kevin Horner-Richardson, William G.
