Abstract: Many automotive radiators are now made with a metallic heat exchanger core and plastic top and bottom portions. A circumferencial lip on the plastic portions receives an O-ring. A flange on the core is folded over the lip and crimped to compress the O-ring between the lip and the flange to achieve a seal. When the crimp loosens, the radiator leaks. Current practice is to remove and replace the radiator since the leak cannot be repaired by brazing. The invention provides a clamp for slipping over the flange at the leak. Rotating one or more screw fasteners on the clamp compresses the crimped portion of the flange at the leak and the O-ring to repair the leak. The clamp remains in place without significant interference with function. The method of repair may be employed without removing the radiator from the vehicle. In may be performed without special skills or tools to greatly reduce the costs of leak repair.

Abstract: A pole clamp assembly (10), and a method of using same, involves two jaws (14, 16) mounted on a base frame, or housing, (12) with a first (14) of the jaws being movable on the frame along two parallel curved tracks between closed and open positions and a selectively-actuatable biasing mechanism (18) comprising an elastic or spring member (38, 102) attached between the movable jaw (14) and a reel or hub (36, 36'). By selectively moving the hub between open and closed positions, the biasing mechanism moves the jaw between the closed and open positions, but if the jaw is held in the closed position, for example, which it will be if the clamp is engaged with a pole, the biasing mechanism flexes when the hub is moved to the open position to allow the movable jaw to remain in the closed position. When the jaw is no longer held in the closed position it snaps to the open position under the influence of the biasing mechanism.

Abstract: The moving parts of the clamping mechanism are enclosed within a hollowed out enlarged casing at the base of the stabilizer post. The hooked base of the post forms the bottom of the clamp. Inside the post casing the hooked top of the clamp is attached to two side panels with angled slots. A screw through a back panel engages a large rectangular nut fitted with angled protruding blocks on each side of the nut. The nut protruding blocks fit into the angled slots of the side panels. The bolt is rotataly fixed at one end so turning it moves the nut forward and backward along the screw. When the bolt is turned and the nut moves horizontally on the bolt, the side panels move up and down. The hooked top of the clamp moves up or down engaging and releasing a side rail of an operating table between the clamp elements. A relatively flat knob to turn the screw is the only protrusion from the post casing at the base.
