Abstract: A tool or accessory that has two parts that needs to be attached comprising of a pin, rivet, screw, etc thru the fulcrum to make it a one part tool. The tools handles is what the invention pertains to. The two handles will be compromised of different grip handles. The said tool or accessory can be comprised of metal or plastic. The over grip that inserts onto the main material of the said tool or accessory can be compromised of rubber or plastic. The handle that does not have the rubber or plastic over grip will have the main tool material as the formed grip.

Abstract: A portable system for treating, for example, cleaning and/or drying, surfaces, including both indoor and outdoor surfaces, is provided. The system includes a pressurized air outlet assembly, or “air knife” assembly, coupled to a source of pressurized air, for example, a blower, a fan, or a turbine. The air knife assembly concentrates a high volume exhaust flow of air into a high velocity, high temperature, and/or high pressure air stream directed at a target surface. The air stream can be angularly varied to propel water, snow, debris, and other particulate from the target surface, for example, a path or roadway being cleaned or dried. The air knife blade assembly is substantially long enough to allow a single lane of roadway or runway to be dried and cleaned in one pass, but can also be shortened to allow treatment of narrower paths.

Abstract: A reaction turbine stator vane segment comprising an integral grouping of plural vanes, an arcuate tip shroud connected between radially inner tips of the vanes, and an arcuate mounting portion extending across radially outer tips of the vanes, the arcuate tip shroud formed with plural seal components extending radially inwardly from the tip shroud.

Abstract: Disclosed herein is a stator assembly for a steam turbine. The stator assembly includes a stacked stator section and a retention device. The stacked stator section has a plurality of adjacently disposed stator plates. The retention device retains the adjacent stator plates proximate to each other.

Abstract: The seal between high and low pressure regions in a turbine or turbo-machinery includes arcuate segments having a brush seal flanked on one or both sides by a plurality of beams lying adjacent to and in contact with one another. Shims separate the bristles of the brush seal from the rows of beams. The cross sectional dimension of the beams is 20-60 times the diameter of the bristles. The beams terminate short of the rotary component while the bristle tips engage the rotary component. The beams take up most of the pressure difference while the bristles take up the balance of the pressure difference across the seal.

Abstract: An integrated nozzle wheel for a turbine stator component includes a three hundred sixty degree wheel formed from a single piece of stock material, a radially inner portion of the wheel machined to include a plurality of nozzles, each having an airfoil portion and a radially inner tip shroud portion; a radially outer portion of the wheel machined to include one or more assembly features.

Abstract: A sealing ring for a turbine housing. The sealing ring may include a sealing face with a number of teeth thereon, an axial slot positioned within the sealing face, a head portion for positioning within the turbine housing, and a connector for attaching the sealing face to the head portion through the axial slot.

Abstract: An abradable coating and/or an abrasive coating applied to the rotor of a steam or gas turbine allows the temperature and pressure drop capabilities of conventional brush seal assemblies to be increased. The pressure drop capability of brush seals is closely related to fence height, i.e., the distance between the rotor and the bottom edge of the backing plate supporting the brush seal wire bristles. Application of the abradable or abrasive coating allows the fence height to be reduced and the pressure capability of a brush seal assembly increased commensurately because the risk of the backing plate rubbing against the surface of the rotor, so as to cause damage to the rotor, is reduced. In addition, the backing plate can be made from a higher strength material that can withstand higher temperatures because any contact between the backing plate and the rotor results in no damage to the rotor, but rather a gradual reduction of the backing plate as it wears.

Abstract: A seal between rotary and stationary turbine components includes an abradable coating on the surface of the stationary component between axially spaced caulked-in seal strips. The rotatable component includes a plurality of axially spaced teeth interdigitated with the teeth of the stationary component and engaging the abradable coating on the stationary component in the cold condition of the turbine. The teeth on the stationary component have larger clearances to prevent mushrooming of the tips in the event of a transient condition. By utilizing caulked-in teeth, a larger number of seal teeth are provided for the same axial extent as compared with conventional labyrinth seal teeth.

Abstract: The turbine includes a diaphragm having a seal carrier mounted in opposition to seal teeth carried by the rotary component. The seal carrier includes a seal face having a coating of abradable material enabling the rotary component to abrade the material from the seal face. The seal carrier is removable from the diaphragm and is carried by an axial extension integral with or removable from the outer diaphragm ring. A spring may be interposed between the seal carrier and the stationary component.

Abstract: A reaction turbine stator vane segment comprising an integral grouping of plural vanes, an arcuate tip shroud connected between radially inner tips of the vanes, and an arcuate mounting portion extending across radially outer tips of the vanes, the arcuate tip shroud formed with plural seal components extending radially inwardly from the tip shroud.

Abstract: The invention provides spray coatings to achieve circumferentially non-uniform seal clearances in turbomachines. In steam and gas turbines it is desirable to assemble the machines with elliptical seal clearances to compensate for expected casing distortion, rotordynamics or phenomena that cause circumferentially non-uniform rotor-stator rubs. The claimed invention allows the casing hardware to be fabricated round, and a spray coating is applied to the radially inner surface such that the coating thickness varies circumferentially, providing the desired non-uniform rotor-stator clearance during assembly.

Abstract: A rotary machine includes a rotatable rotor, buckets radially mounted on and spaced apart about the rotor, a stationary stator/casing disposed about and radially outward from the rotor defining an annular gap between the casing and tips of the buckets, and an abradable seal member provided to the bucket tip portions and disposed within the annular gap such that during differential growth of the rotor and buckets relative to the casing the seal member abrades in response to contact with a base seal member provided to the stator casing. Thereby, clearance between the stator casing and bucket tips is minimized between the moving bucket tips with the stator casing.
