Abstract: A drive coupling hub (60) includes a body (120) and lugs (126) that extend radially from the body (120) and are engageable with a primemover (54) of a primary power source (14). The lugs (126) have a fastening lug (80) that includes a radially extending bore (82). A bearing (88) is set within the bore (82). A setscrew (90) extends within the bore (82) and applies pressure on the bearing (88) to engage the drive hub to a shaft (58) of a secondary power source (16).

Abstract: A tool is provided to retain a fitting component and a tube gripping device prior to assembly of the fitting and tube gripping device to a conduit end. The tool has a retaining portion that is adapted to retain the fitting component and the tube gripping device on the tool as a single assembly. The tool also protects the fitting component, the tube gripping device, and the conduit end after the fitting component and the tube gripping device are assembled to the conduit end. The tool has a protective portion that is adapted to at least partially cover at least one of the fitting component and tube gripping device after the fitting component and tube gripping device have been assembled to the conduit end.

Abstract: The present application relates to valve and actuator assemblies. The valve actuator assemblies may include a capless valve actuating arrangement, include a replaceable passage defining member that includes seal members, include a valve member that is assembled in a valve chamber from an end of the valve body that is opposite an end that a piston is assembled in, and/or include a valve member that may be rotated in a valve body without affecting the ability of the valve member to perform its sealing functions.

Abstract: A stainless steel tube fittings, or components thereof, are color coded by providing an oxide coating of a different color on one or more of its surfaces, the colored oxide coating having a thickness of ?1000 .

Abstract: A welding fixture for supporting first and second workpieces in a coaxial relationship along a workpiece axis relative to each other includes a base, a left clamp on the base for holding a first workpiece, and a right clamp on the base for holding a second workpiece on an opposite side of a welding plane in a coaxial relationship with the first workpiece. The fixture also includes a left handle on the base for operating the right clamp, and a right handle on the base for operating the left clamp.

Abstract: A platform mounted drive train for a professional carpet and floor cleaner system, the platform mounted drive train being formed of a rigid platform; a power plant having two spaced apart mounting structures secured to the rigid platform; a vacuum blower having one mounting structure secured-to-the rigid platform; a rigid structural connector coupled between the power plant and the vacuum blower for rigidly securing the vacuum blower in fixed lateral, angular and rotational alignment with the power plant; and a coupler assembly interfaced between an output drive of the power plant and an input drive of the vacuum blower. The drive train is optionally mounted using one or more vibration isolators.

Abstract: The bandwidth of a group of Internet users, called listeners, is pooled, and that bandwidth is employed to broadcast a data stream, substantially concurrently, to those listeners. A broadcast manager coordinates the connections between the originator of the data stream and the listeners. The originator divides the data stream into a number of channels. Each channel is transmitted over a tree of interconnected listeners. A given listener in a given tree receives that channel from its parent in that tree, and retransmits the channel as it is received to its children in that tree. Each listener is present once in each tree, so the listener receives each channel once. Listeners combine the incoming channels to reproduce the originator's data stream. The result is that almost the entire transmission bandwidth required for the broadcast is provided by the listeners. In some embodiments, a given listener is required to transmit no more data than it receives.

Abstract: The present invention relates to a system for disbursing ozone throughout a poultry house in order to disinfect the same and to reduce the concentration of pathogens found within the poultry house. An ozone generator is associated with the poultry house and ozone produced by the generator is directed through a lower main duct that disburses ozone upwardly through litter disposed on the poultry house floor. In addition, the same generator directs the produced ozone through an upper main duct and ozone is disbursed from conduits leading from the upper main duct into the air.

Abstract: A polymeric material incorporating a polyvalent cation chelating agent in an amount effective to inhibit the growth of an ocular pathogen, particularly a protozoan, can be used to produce eye care products such as contact lens cases and containers for containing eye care solutions and contact lenses.
