A production method is disclosed for separating integrally attached gutter flash from a blow-molded thermoplastic resin product utilizing tensile forces applied to the gutter flash while the product is fully restrained within the closed co-operating product mold in which the product is formed, as well as different embodiments of apparatus suitable for accomplishing the production method in a conventional industrial blow-molding machine.

Method for progressively separating integrally attached gutter flash from an in-mold blow-molded thermoplastic resin product

A method and apparatus are disclosed which are for use in installing the end segments of boiler tubes in the drum walls of a high-pressure steam boiler, and which involve expanding rather than swaging boiler tube end segment metal into intimate contact with grooved boiler tube bores provided in the steam boiler drum walls.

Method and apparatus for installing steam boiler tubes

A boiler tube peeler tool assembly useful in connection with the removal of boiler tube flared-end segments from retention within power boiler header walls is provided with a tool body subassembly, a clamp subassembly carried by the tool body subassembly and having pairs of clamp expansion jaws that engage the boiler tube flared-end segment interior surface, a peeler blade subassembly that bends and shears retained longitudinal gap metal from retention by the boiler tube flared-end segment, and a conventional pressurized-fluid actuator for reciprocally powering the peeler blade subassembly.

Boiler tube flare-end segment peeler tool

A compression tool assembly that is useful in connection with the removal of boiler tube flared-end segments from retention within power boiler header walls is provided with oppositely paired compression jaw elements that are rotated to cause the wall of a longitudinally gapped boiler tube flared-end segment to be compressed into a cross-section configuration that permits comparatively easy tube segment withdrawal.

Boiler tube flared-end compression tool

A power boiler tube removal tool assembly is provided with co-operating shear block cavity, shear blade, and anvil elements that function to shear and inwardly bend gap metal in a boiler tube flared-end segment to thereby facilitate subsequent boiler tube flared-end segment peeling, crushing, and withdrawal steps that complete tube end removal from retention within a boiler drum wall.

Boiler tube segment and bend tool

An apparatus is provided for removing the severed end-portions of boiler tubes installed and retained in a boiler header without consequential boiler header metal damage and in a manner whereby a compression gap of uniform width is machined throughout the length and thickness of each retained boiler tube end-portion selected for removal, the machined boiler tube end-portion is subsequently compressed to significantly close the machined compression gap and reduce the tube end cross-sectional circumference, and the compressed tube end is withdrawn longitudinally from engagement with the boiler header tube-mounting bore.

Boiler tube removal apparatus

A snow vehicle has a hull with a plurality of longitudinally extending bottom sliding surfaces adapted to independently contact the ground and each incorporating a control element to cause the vehicle to be steered as it is rotated about a longitudinal axis. The snow vehicle has an operator platform hull which will accommodate an operator seated on the snow vehicle when the snow vehicle is utilized as a sled and which will accommodate the feet of a rider when the snow vehicle is operated as a snow board.

Snow vehicle

A gap-cutter tool assembly for machining a longitudinal gap in an installed boiler tube is provided with clamp elements that engage the interior surface of the installed boiler tube, a cutter head track that provides a straight line cutting path within the tube interior and in the presence of different tube interior diameters, and a cutter head that co-operates with the cutter head track and that has different elevational positions during the cutter head cutting and return strokes, and at the end of the cutter head return stroke.

Apparatus for effecting boiler tube removal

A method and apparatus is provided for removing the severed end-portions of boiler tubes installed and retained in a boiler header without consequential boiler header metal damage and in a manner whereby a compression gap of uniform width is machined throughout the length and thickness of each retained boiler tube end-portion selected for removal, the machined boiler tube end-portion is subsequently compressed to significantly close the machined compression gap and reduce the tube end cross-sectional circumference, and the compressed tube end is withdrawn longitudinally from engagement with the boiler header tube-mounting bore.

Boiler tube removal method

An improved interlock panel for incorporation into a cargo space divider assembly is provided with a pair of stepped grooves throughout its length to facilitate manual insertion and manual removal of the panel into cooperation with another interlock panel, and with a retention clip member that restricts panel tilt about its base and thereby improves panel vertical stability.

Interlock panel

An interlock panel has a plurality of laterally spaced teeth which define tooth slots and pairs of spaced lugs which define interlock slots. Each tooth slot is aligned with an interlock slot to receive one of the top and bottom area of a panel to provide a double interlock when a pair of panels are joined.
