The connector assembly joins first and second hollow tubular elements. The connector assembly includes an anchor plug inserted into the first hollow tubular element, and having a second anchor plug opening that is elongated. A connector fitting is inserted into an end of the second hollow tubular element, and has a receiving portion to receive an exterior surface of the first hollow tubular element. The connector fitting includes an elongated-shaped receiver extending inward from the receiving portion, and includes a fastener receiver at a bottom of the elongated-shaped receiver. A torsion bar is configured to extend between the anchor plug and the connector fitting, and includes a tapered top defining a wedge. In operation, when a fastener is positioned and tightened, the bottom of the torsion bar is rigidly secured within the elongated-shaped receiver of the connector fitting, and the tapered top of the torsion bar is rigidly secured within the anchor plug via the second anchor plug opening.

The invention is a detection and prevention system to detect and prevent fluid leaks in a property that may cause damage to the property. The sources of the leaks may include, for example, toilets, hot water heater, sinks, washing machines, water makers and broken pipes or other sources of fluid leaks. The inventive may include one or more sender units that may be positioned at various locations on a property. The sender units may have a fluid sensor (for detecting a fluid leak) and a transmitter (for communicating with a base unit). The base unit may receive signals from the transmitter when the fluid sensors detect a fluid. The base unit may then communicate with a main shut off valve to restrict the flow of fluids onto the property.

The invention is an improved reflow tool for performing a reflow process on a wafer. An input robot may be used to transport wafers from an input carrier to an oven where a reflow process is performed. After processing the wafers in the oven, the wafers are transported to a storage carrier. In a preferred embodiment, the storage carrier includes a plurality of left and right slats that use chamfer tabs and centering tabs to precisely position the wafer as the wafer is loaded into the storage carrier. The storage carrier may be part of a buffer indexer that also includes an actuator for vertically positioning the storage carrier. An output robot may be used to sequentially remove the wafers from the storage carrier and to place the wafers in an output carrier. In another preferred embodiment, the power from a main power supply to the reflow tool is monitored and an uninterruptible power supply is used to power the oven and buffer indexer if power is lost. This allows the wafers in the oven to be safely moved to the storage carrier in the event of a loss of power from the main power supply.

The invention is a multiple size workpiece positioning device for the precise positioning or centering of workpieces, such as semiconductor wafers, in a processing station. The inventive includes a plurality of ring bars that may be pivoted on one end. The distal end of the ring bars form a circular shape that may decrease or increase in diameter as the ring bars are pivoted. This movement may be used to position or center the workpiece. A single combination pin or two pins of different heights may be mounted on the distal end of the ring bars. A combination pin or a rest pin and an alignment pin may be used to support the bottom of the workpiece to provide a contact point for an urging force on the edge of the workpiece.

A water pump normally used in a system circulating pool water through a filter cartridge is used to clean the filter cartridge by coupling a 3-way or inline valve and a tee in the piping between the pump and the filter. In a first valve position, the filter housing receives the entire water output from the pump, and in a second position, the entire water output of the pump is diverted to a flexible hose secured to a first water discharge wand . A circular ring-shaped manifold with an array of discharge apertures directs streams of water radially outward into the filter cartridge in a direction opposite the normal flow of water for hydraulically flushing debris from the filter cartridge. A second wand with a C-shaped manifold (FIG. ) is then connected to the hose and used to direct water streams onto the outer periphery of the filter cartridge.

A foldable table comprises a flat table top supported upon a collapsible frame which is removably fitted within the trunk of an automobile or similar space in an automotive vehicle. The frame includes lower frame members which are rested upon the floor of the vehicle and upper frame members which support the table top. The upper and lower frame members are connected together by pivotal table leg members which enable the upper frame members, with the supported table top, to be raised or lowered relative to the lower frame members. The table top is slidably connected to the upper frame members for sliding part-way out of the vehicle. The table top, which normally is in a horizontal, lower, storage position within the vehicle can be manually raised while still horizontal and then slid part-way out of the vehicle for table use. Thus, articles may be supported upon the table in both its raised table use position and in its lowered storage position.

An electric violin includes a body having a top, bottom and a ribcage situated between the top and bottom. A neck is attached to the body and includes an unfretted fingerboard. A bridge is attached to the body and strings extend from the distal end of the neck over the bridge and are attached to the body. The body includes a narrow portion adjacent the neck enabling easy access to the upper portion of the fingerboard. The fingerboard portion of the neck extends over the body a fixed distance. The underside of the neck includes a projection which defines a first registration point normally associated with the fourth finger position of a violin. The neck also includes a second projection located on the underside of the neck that defines a second registration point for a predetermined fingerboard position, preferably the eighth finger position corresponding to a one octave higher position on the strings. An optional third registration location is defined by a groove located on the underside of the fingerboard where the fingerboard extends over the body and is associated with a predetermined finger position near the extreme upper portion of the neck thereby enabling positive fingering of the strings to produce musical notes on the upper portion of the neck. The bridge includes piezoelectric transducers for detecting vibrations of the strings and producing corresponding electrical signals. The transducers are connected to amplifier electronics contained within the body of the violin. Electrical connectors mounted on the ribcage of the violin enable connection of the amplifiers within the body to external power amplifiers.
