Abstract: A demolishing method utilizes an aggregate stack demolishing scaffold apparatus mounted to an upper part of an aggregate stack including four smoke funnels arranged adjacent to each other. An uneven scaffold including one plate-shaped upper scaffold portion is placed on an upper end of each smoke funnel. A lower scaffold portion is coupled to the upper scaffold portion and located in lower positions in the smoke funnels with the upper scaffold portion being placed on the upper ends of the smoke funnels. A chain block suspends and supports the uneven scaffold from and on an inner wall of each smoke funnel, and adjusts a suspending height. With this configuration, the upper scaffold portion is located on the upper ends of the smoke funnels, and thus there is no possibility of contact between the scaffolds in the smoke funnels causing a worker to lose his balance, thereby improving safety.

Abstract: Display module mounting apparatus and methods provide mounting features enabling ease of installation and service. The apparatus may have one or more releasable frame couplers and pivoting releasable frame couplers coupled to a display module having a display plane defined in relation to a substrate.

Concave and convex adjustments to the display plane may be made. Operation of pivoting action to tilt the display plane enables installation, removal, and serviceability of large displays constructed with a tiled plurality of display modules.

Abstract: To produce a combined service brake cylinder and spring-loaded brake cylinder for a vehicle brake system, force-actuation path characteristic curves of the brake system with the elements that can be actuated by a storage spring of the spring-loaded cylinder are measured/recorded under different operational conditions. Force-actuation characteristic curves of different storage springs for use in the spring-loaded cylinder are also measured/recorded. The minimum necessary actuation stroke of the piston of the spring-loaded cylinder and the minimum necessary spring force for a storage spring to effect a parking brake function are determined by the intersection of the force-actuation curves of the brake system with those of the storage springs. The storage spring that generates a sufficient actuation force under certain operating conditions and the dimensions resulting from the smallest possible piston actuation stroke are selected for producing the combined service brake cylinder and spring-loaded cylinder.

Abstract: A manually actuated robotic tool changer comprises master and tool units, each adapted to be connected to a different one of a robotic arm and a robotic tool. The tool changer includes a plurality of rolling members retained in one of the units and a piston mounted in one of the units and moveable in an axial direction. The piston includes a multi-faceted cam surface including an initial contact surface, a locking surface, and a failsafe surface interposed between the initial contact surface and the locking surface. When the piston is in a locked position in the tool changer, the cam surface is operative to contact the rolling members in one of the units and to urge each rolling member against a surface of the other unit to couple the master and tool units together.

Abstract: An apparatus and method for supporting a tubular medical device, such as a stent or scaffold, includes a rod disposed between two collets. The rod can be shaped to form a range of different size or length helical supports to support a wide range of tubular medical devices. The rod is shaped into a full or partial helix by rotating one of the collets relative to the other.

Abstract: A travel system (20) for a canister storage, transfer, or transport system generally includes a support structure (22), at least one traveling device (24) for preparing, inspecting, and/or repairing the canister, and a base ring (26) for supporting the traveling device and providing for rotational movement of the traveling device relative to the support structure.

Abstract: A medical device-includes a scaffold crimped to a catheter having an expansion balloon. The scaffold is crimped to the balloon by a process that includes one or more balloon pressurization steps. The balloon pressurization steps are selected to enhance scaffold retention to the balloon, maintain a relatively uniform arrangement of balloon folds about the inner surface of the crimped scaffold so that the scaffold expands in a uniform manner when the balloon is inflated, and to avoid any possible over-stretching of balloon material.

Abstract: A system and method of making a forged part. The method may include forming a workpiece in a first die unit that may be disposed in a first press, transferring the workpiece to a tooth forming die unit that may be disposed in a second press, and forming the workpiece into the forged part by forming a set of teeth on the workpiece with the tooth forming die unit.

Abstract: A piston assembly mounting apparatus for an engine may include a robot having two multijoint arms movable in a predetermined range, a taking-out unit mounted at a free end of one of the arms of the robot and clamping and taking out one of a plurality of piston assemblies, and a fitting unit mounted at a free end of another of the arms of the robot, receiving and clamping the one piston assembly taken out of the taking-out unit, and then inserting the one piston assembly into a cylinder of a cylinder block.

Abstract: A method of assembling a gas turbine engine includes locating a consumable assembly tool clip within the engine.

Abstract: A training method and apparatus are disclosed. The training method may include converting a firearm capable of firing live ammunition to a pneumatic training device incapable of firing live ammunition. The training method may further include cycling a pneumatic training device through one or more cycles. Each of the cycles may simulate an actual firing of the firearm. Each of the cycles may also include triggering a trigger assembly of the pneumatic training device, using a charge of a pressurized gas to reset the trigger assembly, and advancing a counter of the pneumatic training device. After a certain number of cycles have been completed, a next cycle may be attempted, but not completed. Accordingly, the training method may enable a user to safely and realistically practice reloading, jam or malfunction clearing, or the like.

Abstract: In a method for installation of a transition duct in a gas turbine engine, a guide structure is positioned that extends in an inclined direction with respect to a gas turbine axis. At least a portion of the guide structure is disposed between a turbine section and a combustor section of the gas turbine engine. The transition duct is engaged with the guide structure such that the transition duct is movable along the guide structure. Motion is imparted to the transition duct along the guide structure in a forward-to-aft direction, to move the transition duct to an installed position in which an aft end of the transition duct is aligned for attachment to a forward face of a stator component of the turbine section.
