Abstract: A support assembly for an individual lying in a supine position comprises a first support unit, a second support unit, a first bridge slidably detachably engaging the first and second support units, a head rest, a second bridge detachably interconnecting the head rest and the first support unit, and a hinged torso compression alert strap mounted on and extending over the first support unit and including an indicator reflecting the degree of compression achieved by tightening the strap against the chest of an individual lying supine on the support assembly.

Abstract: A conveyance arrangement for conveying planar circuit boards is characterized by a roller drive in which the individual rollers have an angled driving surface formed thereon. The angularity of the driving surface is selected such that when the surface engages the edge thickness of a circuit board the board, if otherwise unrestrained, is displaced at a predetermined rectilinear velocity. However, if the board is restrained, the driving surface slips with respect to the edge of the board.

Abstract: A tensioning device for the take-up roll in an automatic laminating apparatus is characterized by a clutch member attached to the roll, the clutch member having a clutch material thereon biased into an abutting interface with respect to a drive member. The drive member is rotated at a first predetermined angular velocity. The clutch material continuously slips along the interface with the drive member to impart a second, lesser, angular velocity.

Abstract: A gripping arrangement for removing laminated circuit boards from the lamination region of an automatic laminating apparatus includes a gripping element which grasps the board after a predetermined portion has emerged from the apparatus. A carriage is simultaneously actuated to impose a displacement force on the laminate to assist in withdrawing it from the apparatus.

Abstract: A process for laminating thermoplastic film such as photosensitive film to a panel by continuous advancement and contact preheating of the panel to a lamination step which is discontinuous, being actuated according to position of the panel, to thereby uniformly space the resultant laminates from each other.
