20110117517	LIQUID JET APPARATUS AND METHODS FOR DENTAL TREATMENTS - Systems and methods for using a liquid jet apparatus for dental treatments are disclosed. In one implementation, the liquid jet apparatus may include a handpiece configured to deliver a high velocity liquid jet to a desired location in the mouth of a patient. The handpiece may include a positioning member having a channel through or along which the jet can propagate. The positioning member may have a distal end portion configured to be at least partially disposed in a pulp cavity, canal space, or opening in the tooth under treatment. During operation, the jet may impact an impingement surface of the distal end portion of the positioning member and be deflected as a spray through one or more openings in the distal end portion. The liquid jet apparatus may be used for root canal treatments.	05-19-2011

20110316284	Power Density Enhancement Apparatus For Wind Turbines - A wind deflector apparatus configured for increasing the velocity of an airstream flowing therethrough. The wind deflector apparatus comprises a hybrid conduit with one end comprising a first conduit having a distal end configured for receiving an airstream. The other end of the hybrid conduit comprises a pair of conduits wherein the distal ends of the pair of conduits are configured for releasing the airstream. The proximal ends of the pair of conduits depend together and are sealingly conjoined to the proximal end of the first conduit. The diameter of the distal end of first conduit is greater than the combined diameters of the distal ends of the pair of conduits. The wind deflector apparatus is communicable with wind tunnels and with wind-powered turbine generators. The wind deflector apparatus may have one or more wind-powered turbine generators installed in at least one of the conduits.	12-29-2011

20080286098	Wear minimization system for a compressor diaphragm - Aspects of the invention relate to a system for reducing relative movement between the outer shroud of a compressor diaphragm and the compressor shell of a turbine engine, thereby minimizing the wear and prolonging the life of such parts. Embodiments of the invention include a system for applying a preload on the outer shroud of a compressor diaphragm. The preload can be applied in the axial and/or radial directions. The preload can be applied at or proximate the joint between two shell segments, which is typically the location of the largest relative movement. In one embodiment, the preload can be achieved by providing one or more load applying members that operatively engage the outer shroud. A load applying member according to aspects of the invention includes a first portion, a second portion, and a biasing member operatively positioned therebetween. The biasing member can be a plurality of spring washers.	11-20-2008
