Abstract: A display fixture for holding one or more cycles includes a linear track, a stop, a wheel mount, and a coupling member. The linear track defines a channel along the linear track. The channel is open upwardly and extends from a first end to a second end of the linear track. The stop is secured to the first end of the linear track. The wheel mount is slidably received along the linear track. The wheel mount includes a cam member, slidably interacting with the linear track, and an extension member, extending as an upward bridge between opposing sides of the cam member to receive a wheel of one of the one or more cycles by extending over a portion of the wheel. The coupling member extends through the wheel mount and the linear track to selectively secure the wheel mount in of position along the linear track.

Abstract: A platform fixture for displaying a wheeled good includes a frame, a rail, a wedge stop, and a mounting bracket. The rail extends across a top of the frame. The wedge stop is configured to selectively receive one or more wheels of the wheeled good and includes longitudinal flanges and two coupling flanges. Each of the two longitudinal flanges extends downwardly from a V-shaped top surface of the wedge stop. Each of the two coupling flanges extends inwardly from a different one of the longitudinal flanges. The mounting bracket is coupled to the rail and includes two T-shaped side segments defining a base portion and a cross bar that is wider than the base portion. Each of the two coupling flanges includes a cutout. The wedge stop is coupled to the mounting bracket by placing each base portion within the cutout of a different one of the two coupling flanges.

Abstract: A modular shelving system comprises a first upright, a second upright, first and second rails, and a rail spanner. The first upright includes a first body and a first cleat having a base portion secured in the first body. The second upright includes a second body and a second cleat having a base portion secured in the second body. Each of the first and second rails defines an upper cleat hole and a lower cleat hole. The first cleat of the first upright is slidably received in the upper and lower cleat holes of the first rail, and the second cleat of the second upright is slidably received in the upper and lower cleat holes of the second rail. The rail spanner extends between the first and second rails and includes first and second retaining claws each connected to the rail spanner.

Abstract: A monitoring system is presented. The monitoring system may include a first chemical vessel containing a first chemical mixture and a second chemical vessel containing a second chemical mixture. The monitoring system may further include a sensor configured to selectively receive a first sample flow of the first chemical mixture from the first chemical vessel and a second sample flow of the second chemical mixture from the second chemical vessel. The sensor may be configured to measure a first sample attribute value of the first sample flow and a second sample attribute value of the second sample flow. By multiplexing multiple sample flows through a sensor, the monitoring system may monitor attributes of multiple chemical mixtures without requiring separate sensors for each chemical mixture monitored by the system. In an embodiment, the monitoring system is preferably configured to control an attribute of a chemical mixture.

Abstract: Assembly of a structurally sound modular shelving system includes forming an H-shaped base structure, or otherwise-shaped base structure, by releasably hooking a tie beam into a first base piece and a second base piece. A first column member is slid into the first base piece by sliding an insert tab at an end of an elongate body of the first column into a vertical passage through the first base piece. A second column member is similarly slid into a second base piece. A header member is releasably hooked into the first and second columns, the header member extending substantially horizontally between the first and second columns and substantially perpendicularly to the first and second base pieces.

Abstract: Method and system for purging a process line of a process gas used in a semiconductor wafer fabrication process. Inert gas (e.g., nitrogen gas) is repeatedly charged from an inert gas source into the process line and evacuated using a vacuum system. The vacuum system is preferably supplied with inert gas having a pressure in excess of 30 psig from the inert gas source. The inert gas is introduced into the process line from an inert gas conduit at a predetermined pressure to prevent process gas from liquefying in the process line. A set pressure regulator or an absolute pressure regulator may be used to reduce he pressure of the inert gas to below the vapor pressure of the process gas.

Abstract: Data incorporated in call detail records (CDR), obtained from network switches, are subjected to processing by a statistics engine which maintains separate counts for CDR events relating to certain calls, such as 800 number and 900 number calls. Such events, such as attempted calls, completed calls, and duration, form statistics for network users. Compilation of statistics may be done for different services, such as total summary counts and counts by originating area code. In case of 800 numbers, the statistical counts for the various services are compiled in accordance with the 800 number or 900 number called. When a network user decides to change the statistical services required, this is easily accomplished by changing the rules for interrogating the CDR data, as opposed to the prior art approach of changing programming coding.

Abstract: A laser welding apparatus comprises a mount attached to a laser beam delivery system and a cylinder attached to the mount. A piston having first and second piston ends and a piston body sealingly and slidably engages with the cylinder dividing the cylinder into first and second piston chambers. The piston is slidable between an extended position and a retracted position and has a central axial bore through which a supplemental wire is fed.

Abstract: An apparatus comprises a fixture for positioning a first sheet metal part in proximity of a second sheet metal part so that each sheet metal part has one surface facing the other sheet metal part across a gap and one surface facing away from the other sheet metal part, wherein at least one of the sheet metal parts comprises galvanized steel. A laser beam delivery device applies a laser beam to one of the facing away surfaces. A feed wire source provides a feed wire comprising a supplemental wire and a reactive agent at an intersection of the laser beam and the one facing away surface. The apparatus affects relative movement between the one facing away surface and the laser beam to provide a laser weld between the two sheet metal parts.
