Abstract: A method and apparatus for removing the lowest workpiece from a stack of a plurality of substantially similar workpieces. A horizontal shuttle has a lip on its edge, and is driven in one direction to remove the lip from a void beneath the stack, thereby permitting the stack to fall. The lowest workpiece drops into the void, and the next higher workpiece rests on the upper surface of the shuttle lip. The shuttle is subsequently reversed to drive the workpiece into a slot in a vertical clamp body. The clamp body is driven downwardly, thereby driving the workpiece downwardly, to be acted upon by a secondary device, such as a conventional degating apparatus.

Abstract: A testing method and apparatus for determining whether surgical cartridges have excess drivers. A blade is disposed in the slots of the cartridge and displaced while it contacts the floor of the slot. If an excess driver is encountered, the blade is displaced away from the floor and this movement is detected, preferably by an electronic sensor. The apparatus includes a base plate to which a carriage is mounted, either directly or through other structural members. The carriage is configured to slide along a pair of parallel shafts, and is driven by a pneumatic ram or other linear prime mover. A tooling plate is moveably mounted to the carriage, and the blade is mounted to the tooling plate. Movement by the blade due to excess drivers results in movement by the tooling plate relative to the carriage, which is detected and recorded, such as by a computer.

Abstract: A method and apparatus for moving objects, such as pallets, between an upper horizontal conveyor and a lower horizontal conveyor. A lift raises the pallet from a lower conveyor, and a clamp disposed above the lift with inwardly and outwardly pivotable arms, having inwardly facing fingers at the ends of the arms, clamps the pallet and raises it up to be substantially coincident with the upper conveyor's pallet-supporting surface. A pusher displaces the pallet from the fingers to the upper conveyor. The apparatus can also be operated in reverse to lower pallets from an upper conveyor to a lower conveyor if a fastener, such as electromagnets, is mounted to the end of the pusher.

Abstract: A method and apparatus for moving loaded pallets from one location to another, such as from a region of an assembly line to a vertically lower region of the same assembly line. A first conveyor track is angled downwardly from a source of loaded pallets toward a diverter, which is driven to pivot about one end. The diverter receives the pallet when the diverter is parallel to the first conveyor track and then pivots to a horizontal orientation at which it is unloaded. Upon the last object on the pallet being removed, the diverter pivots downwardly to become parallel to a second conveyor track that is angled downwardly from the diverter, and is released to slide down the second conveyor track. The pallet is preferably precisely located and clamped in the diverter.

Abstract: An improved method and apparatus for inserting surgical staple drivers into a cartridge, including a base, a cartridge-receiving plate having a channel, upper and lower degating plates having a passage through them, a knife with a sharp edge adjacent the passage and a plunger apparatus that drives the drivers downwardly through the guide passage and into pockets in the cartridge. A cartridge locator plate seats the cartridge against stops in the channel. The cartridge-receiving plate is adjustable relative to the base. The upper and lower degating plates and the knife are not adjustable relative to the base, which avoids the need for re-alignment of the knife and degating plates upon re-mounting on the base. The cartridge-receiving plate is aligned relative to the base. A top riser is adjustably mounted to the base, and a cylinder arm, which holds the plunging apparatus, is non-adjustably mounted to the top riser.

Abstract: Resistance to deformation of a support spring for the mask-frame assembly of a cathode ray tube is improved by adding strengthening ribs running longitudinally along the edges of the body and partially into the base of the spring.
