Patent number: 8052753Abstract: The present invention is directed towards a prosthetic anchor (36) including a central layer (1) through which embedded fibers (2), such as artificial tendons, pass in defined pathways (4), a ‘deep’ surface membrane (7) which interfaces with a hard structure, whether that is a prosthesis, a bone, or other hard tissue, and a ‘superficial’ surface membrane (8) which interfaces adjacent tissue and may be configured to adhere or not to adhere to that tissue. The central layer (1) is positioned intermediate the surface membranes (7, 8) which are mechanically and/or adherently attached thereto. Also, non-limiting examples of methods of fabrication and of affixing the anchor (36) to a relatively rigid structure, natural or prosthetic, in a human or animal body with improved stress distribution in the fixed tension member end are taught.Type: GrantFiled: January 9, 2006Date of Patent: November 8, 2011Assignee: University Of CincinnatiInventor: David Boyd Melvin

METHOD FOR REDUCING THE FORMATION OF BY-PRODUCT DINITROBENZENE IN THE PRODUCTION OF MONONITROBENZENE
Publication number: 20110218368Abstract: A method for making mononitrobenzene using a plug flow reactor train. Benzene, nitric acid and sulfuric acid are introduced into the reactor and produced mononitrobenzene is removed at an outlet end. All of the benzene and at least part of the sulfuric acid are introduced at the inlet end of the reactor. A first portion of the nitric acid is introduced by a first nitric acid feed into the inlet end and a second portion of the nitric acid is introduced at one or more additional feeds that are spaced between the inlet end and the outlet end. The method results in reduced formation of by-product dinitrobenzene, improving the reaction yield of mononitrobenzene while avoiding the need for a distillation step.Type: ApplicationFiled: November 14, 2008Publication date: September 8, 2011Applicant: NORAM INTERNATIONAL LIMITEDInventors: Sergio Berretta, David A.

Patent number: 7753837Abstract: Actuator mechanisms on the heart are of several types. In preferred embodiments, they are generally simple, durable, mechanical assemblies and are driven by power delivered from a remote location, generally outside the chest, by a variety of mechanisms. The invention teaches physical mechanisms (1) for transfer of cyclic power from outside the chest to the region of the heart for that purpose, either as translational or rotary motion. Also taught are electromechanical converting mechanisms suitable for delivering power to those transfer devices. The embodiments described herein for either transmission of energy from a site of generation to a conduit (2, 10, 22), and of conduits that then deliver energy to heart actuators, have contours and interfaces designed to promote a favorable biologic response similar to the pseudosynovial capsules that surround artificial joints. Further, design features are chosen to avoid both non-vented gas-filled chambers and static collections of tissue fluid.Type: GrantFiled: December 8, 2005Date of Patent: July 13, 2010Assignee: The University of CincinnatiInventor: David Boyd Melvin

Publication number: 20090297332Abstract: Apparatuses and methods are provided for a wind diverter at least partially encircling a wind turbine support column to direct the wind from an area around a wind turbine to the rotor blades of the wind turbine. The wind diverter may also reduce turbulence and increases the laminar flow of the airstream delivered to the rotor blades. Additionally, the wind diverter increases both the volume of air and the velocity of the airstream reaching the rotor so as to increase the rotor speed. Increasing the rotor speed increases the energy available to the wind turbine. Energy increases as the cube of the rotor speed and the increased energy produces an increase in the power generated by the wind turbine. The wind diverter also allows a wind turbine to begin producing energy at lower initial wind speeds due to the concentration of air.Type: ApplicationFiled: May 28, 2009Publication date: December 3, 2009Inventor: Stephen David Boyd

Publication number: 20090074389Abstract: A method for generating heat includes passing a liquid between electrodes connected to an alternating current power supply. The liquid must have a sufficient level of electrolytes or dissolved minerals so as to be effectively heated. The level of current applied to the electrodes is preferably monitored and controlled. Exothermic, electrochemical reactions occur within the liquid and at the surface of the electrodes. More particularly, the electrodes are comprised of a material that can be oxidized, and the oxidation process during operation of the heater supplies additional current to heat the liquid.Type: ApplicationFiled: October 10, 2008Publication date: March 19, 2009Applicant: LEXINGTON ENVIRONMENTAL TECHNOLOGIES, INC.Inventors: Nathan H.
