A deployment system for an upper bundle steam generator cleaning/inspection device, the deployment system including an elongated body feedable through an access in a steam generator shell proximate the tube sheet of the steam generator, the elongated body flexible in one configuration to bend into a position for extension up through flow slots in support plates of the interior of the steam generator, and rigid in another configuration for positioning and supporting cleaning/inspection devices up through the steam generator proximate the upper tube bundles of the steam generator; and a drive device for driving the elongated body up through the support plates and for retracting the elongated body back down through the support plates.

Deployment system for an upper bundle steam generator cleaning/inspection device

A sliding lance guide flexible lance system (10) is attached to a hand hole (12) of a nuclear power plant steam generator by means of flange (14) of tilt module (16). A rail (18) extends from the tilt module (16) to a support stand (20) and is attached to the stand (20) by a pivot (22) so that the rail (18) is free to rotate with the tilt module (16). A tilt drive motor (24) is attached to the tilt module (16). A flexible lance (26) extends into the rail (18) for extension through a lance guide shoe (27). The lance guide shoe (27) deflects the lance from the rail (18) into the tube gap of the steam generator. The lance guide shoe (27) is slideably mounted in the rail (18), and is attached to a lance guide belt (30), which extends within and along the rail (18). Similarly, the flexible lance (26) extends within and along the rail (18). A lance guide belt sprocket drive (40) is mounted on support (33) to engage the lance guide belt (30). A similar flexible lance sprocket drive (42) is mounted on the support (33) to engage the flexible lance (26).

An apparatus (10) for the location and removal of foreign objects from a difficult to access geometry utilizes a flexible lance (12) formed of individual hose bar segments (14) strung on cables (16) to give a structure that is flexible along its length and fairly rigid in a direction transverse to its length. Extending from working channels (18) of nozzle block (20) of the lance (12) are a pair of multi-prong retrievers (22). A miniaturized Videoprobe camera (24) is provided in the nozzle block (20) between the two retrievers (22). The retrievers are each connected to an actuating cable (26), which extends through the flexible lance (12) to a manual control (28). The camera (24) is connected by a cable (30) to suitable video processing circuits for generation of images on a video display (32). The cable (30) also houses a fiber optic bundle which conveys light to the area being serviced by the lance (12). The flexible lance (12 ) extends through a transporter (34), which positions the nozzle block end of the lance (12) opposite a portion of a steam generator or other difficult to access geometry. The transporter (34) moves along a transport rail (36) to move the nozzle block end of the lance (12) into position. The lance (12) is then advanced through the transporter (34) to move the nozzle block end into the difficult to access geometry and retracted to withdraw the nozzle block end from the difficult to access geometry.

The present invention provides a novel deflator means for expelling excess air from packages which is used in connection with form, fill and seal packaging machines, said deflator means comprising flexible walled, fluid-filled bladder means which engages a product-containing bag and forces excess air out from the bag, the bladder fluid also being provided to be in communication with a reservoir which permits fluid exchange between the bladder, and the reservoir during the packaging cycle.

A flexible lance and drive system (10) extends through manhole (12) into blow down lane (14) of a pressurized water reactor (PWR) steam generator secondary side assembly (16). The system (10) includes a support rail (18) passing through the manhole (12) and along the blow down lane (14). A transporter (20) is suspended for locomotion along the support rail (18). A flexible lance (24) extends through the transporter (20) and can be driven by the transporter into tube bundle (26) to a greater or lesser extent as required to observe and/or clean sludge deposits (28) within the tube bundle (26). High pressure hoses (34), nitrogen purge line (36) and Fiber optics cable (32) is supported by a spacerless hosebar structure (38). The hosebar structure (38) is integrally formed from a flexible plastic material in a single piece.

A tobacco particles separator utilizes turbulent air flow, flow vortices, and a random spread matrix in an air circulation path to separate and singularize tobacco particles. A moving porous web is used to receive and to hold the separated particles which may be retained on the porous web for subsequent analysis.
