Abstract: A pressurized hydraulic fluid actuated coupling assembly for detachably coupling to an element. The assembly has first and second concentric walls secured together at the ends. The second wall is adapted for engaging the element. One of the walls has grooves defining corresponding recesses between the first and second walls. Ridges on such one wall are defined between adjacent recesses. Means is provided for introducing hydraulic fluid into the recesses. Means is provided for varying the pressure of the hydraulic fluid such that in the absence of fluid pressure, the ridges on the one wall are in contact with the other wall and upon pressurization of the fluid the second wall moves away from the first wall such that the second wall rigidly couples to the element and such that the ridges are spaced a predetermined distance from the other wall.

Abstract: An automatic, cam-actuated precision transfer apparatus operable to transfer and simultaneously invert workpieces between adjacent work stations. The transfer apparatus utilizes a common input shaft to provide input rotation to both a stationary oscillator device as well as an indexer device rotatably mounted atop the oscillator. The output of the oscillator device horizontally oscillates the rotatable indexer device through a desired number of degrees of rotation, and the indexer's output vertically indexes a turret-type transfer arm assembly which has associated pick and place units. The combined indexing and oscillating movements produced by the transfer apparatus allow a workpiece to be picked up at a first work station, vertically inverted while being horizontally transferred, and finally deposited at a second work station. The transfer apparatus is adjustable to accommodate any variations in manufacturing setups.

Abstract: The method of die casting a metallic cast product having a hollow metallic member embedded therein by locating the hollow member in position in a casting cavity and injecting molten metal into the cavity around the hollow member including confining a pressure resisting medium within the interior of the hollow member by seals prior to injecting the molten metal into the cavity, thereby positively preventing the hollow member from being collapsed by the pressure of the molten metal injected into the cavity. The pressure resisting medium is sealingly confined within the hollow member by tightly applying a sealing plug to the respective open ends of the hollow member after the pressure resisting medium completely fills the hollow member. One of the sealing plugs may be movable in response to the increase in the internal pressure of the pressure resisting medium. The movable plug is located in cooperation with a plunger actuated by a fluid actuated cylinder mechanism so as to apply to the movable plug a constant resisting force resisting against the internal pressure of the pressure resisting medium. This permits the movable plug to be moved depending upon the increase in the internal pressure of the pressure resisting medium so as to relieve the internal pressure and prevent the hollow member from being damaged due to the excessive internal pressure of the pressure resisting medium.
