Abstract: A trough assembly with adjustable drain is provided. The trough assembly is designed to address seepage problems associated with traditional drain and trough industry standard installation methods. The trough assembly includes a drain assembly. The drain assembly includes a seepage flange. The seepage flange includes a collar having open-ended slots. These slots are configured to cooperate with coupling protrusions to allow for adjustability of the drain assembly. This adjustability allows for accommodation of construction errors, including, but not limited to, variations in the elevation of the finished floor elevation. The seepage flange is also configured to collect seepage fluids into the central aperture of the drain assembly.

Abstract: An improved fluid management system for irrigation of a body cavity and in particular for use in arthroscopic surgery having a pressurized fluid circuit for supplying irrigation fluid and a vacuum fluid circuit for withdrawing waste fluid from the cavity. In a preferred embodiment there is an uninterrupted fluid supply comprised of a plurality of sterile solution saline bags with an automatic spiker to perforate the bags. The system is processor controlled with numerous safety and design features to automate arthroscopy to the highest degree possible. Some of the features include the monitoring and tracking of cavity pressure and flow rates to predetermined pressure and flow rates, tracking cavity to mean blood pressure, overpressure protection, a plurality of pressure and flow rate baseline settings, monitoring, setting and controlling saline supply, and specialized functions for providing pressure and flow rates for typical surgical procedures such as lavage, clear view, and burr/shaver.

Abstract: A continuously variable drive transmission which includes journals and counterweights which are simultaneously displaced in opposite radial directions by operation of a cam keyed to a rotatable operating shaft extending axially through a crankshaft to vary the eccentricities of each connecting rod big-end and thus vary the throw of the crankshaft.

Abstract: An actuating mechanism for adjusting the angular relationship of co-axial primary and second drives while both are running comprises a double planetary gear train having a freely rotatable common sun gear (201) and first and second ring gears (213, 223) rotatable relative to each other and each coupled to the sun gear by respective sets of caged planet gears (208, 218). One ring gear (213) is normally held against rotation and the other (223) is adjustable relative thereto. The gear cages are fast with the respective drives.

Abstract: The disclosure relates to a process for the fabrication of low cost dual property turbine rotors having blades that are diffusion bonded to a blade ring that is simultaneously diffusion bonded to a central hub.

Abstract: The disclosure relates to a turbine rotor and method of manufacture thereof. A plurality of blades having dovetails at the radially inner ends thereof are arranged in a circumferentially spaced circular array. A metallic hub is cast about the dovetails of said blades which are metallurgically bonded by the operation. Alternatively, the blades may be joined to the hub thereafter by an electron beam weld that extends axially to the rotor.
