Abstract: A throttle body assembly for a combustion engine includes a throttle body having a pressure chamber including a supply of liquid fuel, and a throttle bore with an inlet through which air is received. A throttle valve is carried by the throttle body with a valve head movable relative to the throttle bore. A metering valve is coupled to the throttle body, and has a valve element that is movable between open and closed positions. A boost venturi is located in the throttle bore and has an inner passage that is open at both ends to the throttle bore. The boost venturi has an opening through which fuel flows into the inner passage when the valve element is in the open position, wherein fuel flows from the pressure chamber to the metering valve under the force of gravity or under a pressure of less than 6 psi.

Abstract: A filtration vessel is provided with improved sealing surfaces and alignment methods. The sealing surface is provided by a perforated sleeve within the filtration vessel. An alignment mechanism is provided which allows for improved servicing of the filtration vessel.

Abstract: Multi-stage filtration apparatus is provided. A fluid is forced through different filter stage elements allowing for removal of various contaminants from the fluid.

Abstract: A filtration device that includes a pressure vessel having an inlet and an outlet, the filtration device configured to filter a pressurized fluid stream. In an embodiment, the filtration device has at least one disk-shaped filter element housed within the pressure vessel arranged to filter fluid flowing from the inlet to the outlet, and an inlet flow tube disposed within the pressure vessel proximate the inlet tube, wherein the inlet flow tube is configured to direct the pressurized fluid stream from the inlet tube towards a central portion of the at least one disk-shaped filter element.

Abstract: A filter element that includes a disk-shaped filter medium having an axially upstream surface, an axially downstream surface, and an outer peripheral surface extending axially therebetween. An embodiment of the filter medium has a radial inlet flow surface formed along the outer peripheral surface. Further, there is an inlet flow surface formed along the axially upstream surface, wherein a fluid is able to flow both radially and axially through the filter element.

Abstract: There is disclosed a method and apparatus for treating fluid in a fluid treatment system with self-cleaning filters. The liquid treatment system includes a tank defining an interior volume of at least 25 gallons. The tank includes a gravity settling portion proximate a lower end of the tank and generally configured in a frustoconical shape. A self-cleaning filter device is coupled to a top portion of the tank. The self-cleaning filter device is configured to filter out solids from fluid entering the tank and return filtered solids to the tank. Solids in the fluid, entering the tank, are removed from the fluid both by the filter device and by gravity.

Abstract: A fifth wheel hitch for towing a trailer behind a motor vehicle is adjustable between a forward position and a rearward position. The fifth wheel hitch includes a base assembly for mounting to the motor vehicle, head assembly for engaging the trailer and at least one pivoting arm coupled between the base assembly and the head assembly. The head assembly moves in an arcuate path between the forward position and the rearward position as the pivoting arm articulates relative to the base assembly. Once positioned in the forward or rearward position, the head assembly is locked relative to the base assembly so as to prevent further movement.

Abstract: A fifth wheel hitch cart is used for positioning a hitch in a truck bed. The cart is provided with a plate and a pivoting arm disposed between a rolling device and the plate. At least one handle is coupled with the plate. A plurality of cams are operably coupled with the at least one handle and disposed between the plate and the pivoting arm such that rotational movement of the handle causes the cams to lift the plate.

Abstract: The present invention provides a method and system for connection verification. An embodiment includes a DSL based system, with a tester resident at a central office respective to a DSLAM. When a problem is encountered by a subscriber, the tester can be readily connected to the DSLAM to allow performance of tests on the connection between the tester, the DSLAM and the Internet. If such tests are successful, then service provider can eliminate that portion of the link as the source of the connectivity problem. If unsuccessful, the service provider can repair that portion of the connection, and thereby potentially obviate the need to send a technician to the subscriber premises.

Abstract: There are disclosed methods and systems for verifying a connection between a subscriber station and a network wherein a gateway resides intermediate the subscriber station and the network. A method may include receiving instructions from a remote verification host. In response to the instructions, a tester may be introduced into the connection. The tester may receive an IP address of the subscriber station. The tester may use the IP address to perform at least one connectivity test between the gateway and the network. The tester may generate an output reporting a result of the at least one connectivity test.

Abstract: A novel method and system for testing network connections is provided. In an embodiment, the system includes a network, such as the Internet, which is connected to subscriber devices in a subscriber site via an service provider, a gateway in a telephone company central office, and a DSLAM in an open plant interface. The system also includes a test apparatus operable to inject itself in the connection between the subscriber devices and the Internet at the gateway. The test apparatus can mimic the service provider and, thereby connect directly with the device at the subscriber site and try to test network connections for issue between the service provider and the device. The test apparatus can also mimic the customer and, thereby connect directly with the device and the test network connections between the service provider and the device.
