Abstract: A rotor includes a shorting ring defining a plurality of cavities therein, and a plurality of conductor bars each integral with the shorting ring and having an end disposed within a respective one of the plurality of cavities. The shorting ring and each of the conductor bars are formed from an aluminum alloy including a lanthanoid present in an amount of from about 0.1 part by weight to about 0.5 parts by weight based on 100 parts by weight of the aluminum alloy. An aluminum alloy, and a method of forming a rotor are also disclosed.

Abstract: A partial-leg support and method for comfortable, adjustable, cleanable, and portable support for the leg stump or stumps remaining after partial amputation of the leg or legs while seated.

Abstract: A motor has an engine block with cylinders arranged to fire in a firing order. A recirculation system delivers combusted mixture from a cylinder which has just fired to at least partly mix with fuel for the next cylinder in the firing order. Injector bodies (401-405) are associated with each cylinder. Each injector body (401-405) has an internal chamber (424) in communication with a fuel inlet port (426) for delivering fuel into the internal chamber, a fuel outlet port (428) for delivering fuel under pressure from the chamber into the associated cylinder and a combusted mixture out-let port (442). The combusted mixture outlet port (442) of each injector body (401-405) is fluidly connected to the combusted mixture inlet port (438) of the next cylinder in the firing order. Alternatively, the recirculation system is arranged substantially internally within the cylinder head.

Abstract: An axial motor (100) driven by opposed pistons/cylinder (101a–105b, 111a–115b) pairs arranged in a circular array about a central axis of the motor (100). The opposed pistons (101a, 101b; 102a, 102b; 103a, 103b; 104a, 104b; 105a, 105b) in each pair are linked by a corresponding connecting rod (106–110), which transfers the thrust from the pistons (101a–105a) to an output shaft via a power transmission apparatus (300) and z crank (114) arrangement. Reciprocating couplings disposed in the transmission apparatus (300) connect the connecting rods (106–110) to the apparatus (300). During operation, the reciprocating couplings oscillate to retain the connecting rods (106–110) substantially aligned with the corresponding piston pair to reduce side thrust on the pistons.

Abstract: The invention provides methods for reducing circulating levels of antibodies, particularly disease-associated antibodies. The methods entail administering effective amounts of epitope-presenting carriers to an individual. In other embodiments, ex vivo methods for reducing circulating levels of antibodies are provided which employ epitope-presenting carriers.

Abstract: The present invention relates to an axial two-stroke motor (100) which includes an integral turbocharger (308). The motor (100) includes more than two cylinders (101-105) arranged in a substantially circular arrangement about a longitudinal axis (305) of an engine block (106). A chamber is disposed in the engine block (106) which forms an exhaust duct (307) and an intake duct (306). The turbocharger (308) is disposed in the chamber so that it is substantially located within the engine block (106). An exhaust turbine (107) of the turbocharger (308) resides substantially in the exhaust duct (307) and a compressor turbine (200) resides substantially in the intake duct (306).

Abstract: A multipurpose residential plumbing and fire sprinkler system or, more simply, a multipurpose piping system ("MPS") is a system for providing water to both domestic uses (e.g., showers, sinks, toilets) and to sprinklers for fire protection. The invention provides an apparatus and method for alarming when one or more sprinklers connected to the MPS are activated by a fire. The invention uses a water flow detector. In particular, the invention provides an apparatus and method for distinguishing typical domestic water flow from the flow caused by one or more sprinkler heads.

Abstract: An electrolyte chamber includes a cathode movable in the chamber toward a workpart to machine same and spaced from a wall of the chamber by a transverse clearance space and further includes a sealing piston movable transversely in the chamber in opposite directions toward and away from the cathode to substantially close off or open the clearance space. The sealing piston includes one or more fluid passages extending therethrough such that electrolyte pressure exerted on the sealing piston is substantially balanced in the opposite directions of movement such that unbalanced electrolyte pressure forces do not prevent the sealing piston from closing off the transverse clearance.
