  • Patent number: 5904358
    Abstract: A chuck device has a pair of grippers pivotally supported in a recess defined in an end of a body for angular movement about a predetermined angle, a joint member connected to a piston reciprocally movably disposed in a cylinder chamber defined in the body, and a pair of rollers engaging respectively in grooves in the grippers and angularly movably mounted on the joint member. Linear movement of the piston can be transmitted as angular movement to the grippers through the rollers while the rollers are angularly moving with respect to the joint member. A cover is mounted on the end of the body in closing relation to the recess.

  • Patent number: 5826866
    Abstract: Each of a plurality of thin-walled workpieces is held for machining in a machine in a respective rigid holder. Ends of unmachined workpieces are each first imbedded in a molten body of a metal alloy having a melting point between C. and C. contained in a respective one of the rigid holders in a cooling station and having a negative expansion coefficient. The holder and the alloy body are cooled in the cooling station to solidify the body around the imbedded end of the unmachined workpiece and the cooled holder is displaced with the unmachined workpiece from the cooling station into the machine. After machining of the workpiece in the holder, the holder is displaced from the machine into a heating station where it is heated to melt the alloy body. Then the machined workpiece is lifted out of the molten body in the heating station and the holder with the molten alloy body is recirculated from the heating station to the cooling station.

  • Patent number: 5741111
    Abstract: An electro-pneumatic machining jig is adapted to be attached to the bed of a machine such as a milling machine, grinding machine or the like. The jig holds a workpiece, such as a cylinder head, for machining in a desired position relative to a tool head. The machining jig has a pair of jig stands (10) for clamping the workpiece therebetween, with the jig stands (10) mounted in selected spaced relationship on the bed of the machine. Each jig stand (10) has a workpiece connection means (22, 25) mounted on an adjustable stand (16, 17, 18). The stand is supported on a base (11, 12) which includes air-float means (54, 55, 50) and electromagnetic means (13, 53). The air-float means (54, 55, 56) permits alignment of the clamped workpiece relative to the tool head whilst the bases of the pair of jig stands (10) are floating. When the air-float is terminated, the electromagnetic means (13, 53) are energized to clamp each jig stand (10) to a mounting plate on the machine.

  • Patent number: 4984775
    Abstract: A woodworking corner clamp assembly having two screw clamp assemblies, each clamp assembly being oriented perpendicular to one leg of an L-shaped frame. Each clamp is also capable of longitudinal sliding movement along one leg of the L-shaped frame. The longitudinal position of each clamp along the respective leg of the L-shaped frame is controlled by the rotation of a threaded rod which passes through a longitudinal slot located in the leg of the frame and through a portion of the base of the clamp member, such that rotation of the threaded rod causes the clamp to be driven longitudinally along the length of the frame.

  • Patent number: 4835851
    Abstract: A clamp is provided for securely aligning opposed longitudinal halves of a pipe. The clamp comprises a support having a recess therein for receiving a portion of the pipe. First and second levers are pivotably mounted to the supports on generally opposite sides of the recess therein Each lever includes opposed gripping and actuating ends. A piston and cylinder assembly extends between and is pivotally connected to the actuating ends of the first and second levers. As a result, the movement of the piston relative to the cylinder causes the sequential rotation of the first and second levers about their respective pivotable mountings to the support, to securely urge the gripping ends thereof into contact with the pipe mounted in the recess of the support.

  • Patent number: 4712295
    Abstract: A process and an apparatus for forming an air gap pipe are provided. Inner and outer pipes are bent or deformed into comparable configurations such that the inner pipe can be mounted within the outer pipe. The outer pipe then is split longitudinally by a preprogrammed cutting apparatus. The cutting of the outer pipe terminates just short of the complete longitudinal length of the pipe to facilitate rematching later in the process. The cutter includes a follower to trace the actual configuration of the pipe and thereby to offset differences from one pipe to the next. An array of clamps are provided to align the outer pipe halves relative to one another and to facilitate the reattachment.

  • Patent number: 4700935
    Abstract: A fixture for supporting integrated circuit packages during wave soldering of leads on the packages includes a carrier portion including two sets of orthogonal support members. The support members have formed edges for defining seats for receiving the packages. A frame cover includes appendages for engaging the packages and maintaining the packages in the seats. The arrangement of the orthogonal support members and cover appendages facilitates solder wave access to all leads of the packages and cleaning and drying of the packages. Heat transfer from the molten solder during the wave soldering procedure is minimized due to the low mass of the cover appendages.

  • Patent number: 4260347
    Abstract: In the invention, an apparatus is designed for producing spacer frames for insulating glass window structures, made up of lengths of hollow molding joined together by male cornerpieces. Hollows and spaces at the corner joins are sealed or filled by injection of a sealing composition forced in by the use of a female injection head designed to take up a frame corner, and a driver for pushing the frame corner structure into the injection head. There is furthermore a work table for the frame parts in the working position on injection of the compound or sealant, and gripper structures for keeping the hollow molding lengths, forming the corner, in the desired position. At least one of the gripper structures is able to be moved towards the put-in male part of the cornerpiece after the hollow molding part has been gripped.

  • Patent number: 4129292
    Abstract: The specification and drawings disclose an anode assembly for use in electrolytic cells, and apparatus for forming such assemblies. The anode assembly comprises an anode riser to which is joined a parallel pair of metal sheets which form anode surfaces. The sheets are joined to the riser by connecting means which permit movement of the sheets toward and away from one another while maintaining their parallel relationship. Additionally, the connecting means is such that it maintains a tension on the sheets to prevent them from warping or assuming a non-planar configuration. The disclosed apparatus permits assembly of the sheets to the riser in a simple, rapid manner.
