  • Publication number: 20090140481
    Abstract: A solid surface clamp is provided. The solid surface clamp has a top jaw and a bottom jaw. A connecting rod is attached to one of the jaws, and slideably extends through the other jaw. Alignment surfaces may be incorporated into the jaws to assist in accurately positioning the material to be laminated. A compression device is connected to the portion of the connecting rod that extends through the jaw. A shroud shields the compression device, thereby protecting the compression device from contamination by the laminating adhesive. An elongated stiffening member may be used to apply the clamping force over a longer surface, allowing for greater spacing between clamps and extended regions of even clamping pressure.

  • Patent number: 5971378
    Abstract: A clamp is provided that has a pair of clamp bodies which each have an inner surface. The inner surfaces of each clamp body are oriented to face one another in a spaced parallel relationship. A pair of parallel scissors linkages are coupled to the device that operate to move the clamp bodies in parallel relation relative to one another. Each scissors linkage extends from one side surface of one clamp body to a corresponding side surface of the other clamp body. A threaded rod is coupled to the pair of scissors linkages between the clamp bodies and is oriented with its axis of rotation parallel to the inner surfaces of the clamp bodies. The threaded rod is operable to move the clamp bodies either towards one another or away from one another in spaced parallel relation by rotation of the rod.

  • Patent number: 4807059
    Abstract: An electromechanical vault cartridge receptacle has an opening for inserting a vault cartridge, the cartridge passing between a pair of laterally biased rollers which continuously engage asymmetrically contoured sided surfaces of the cartridge. A front surface edge of the cartridge bears upon and causes the backwards motion of a movable frame, the motion of which causes top and bottom surfaces of the cartridge to be securely engaged between an opposed pair of horizontally planar cartridge bearing members. The backwards motion of the movable frame also results in roller supporting members to be locked when the cartridge is fully inserted, thereby preventing lateral movement of the rollers. A cartridge ejecting means comprises electromechanical means adapted for engaging a back surface of the movable frame to move the movable frame in a forwards direction, disengaging the cartridge engaging members and unlocking the roller supporting members, whereby the cartridge is pushed back out of the opening.
