Abstract: An adapter for modifying a spring clamp for use as an edge clamp. The adapter is essentially a flexible intermediate section with pockets attached at each end. Each pocket slips over one of the jaws of the spring clamp. When the clamp is forced open, the intermediate section extends from jaw to jaw across the jaw cavity of the clamp. When the clamp is placed over a workpiece, the intermediate section of the adapter deforms elastically around the contour of the workpiece that extends into the jaw cavity. The edge clamp exerts an edge-clamping force against the workpiece in a direction that is substantially perpendicular to the clamping forces exerted by the jaws and parallel to the longitudinal axis of the spring clamp.

The holder and oil filter may then be placed in a vice, and the filter cut open in accordance with established procedures.

Abstract: A dual force rapid action lever clamp provides clamping forces essentially perpendicular to each other for accurate alignment of face frame stiles of adjacent cabinet units. The clamps are used to tightly draw together stiles of adjacent cabinets while at the same time providing pressure at the front of the stiles resulting in a tight and flush installation of the cabinets. While in a clamped position holes can be drilled and countersunk and installation screws can be driven through a drill guide hole assembly which is built into one jaw of the clamp. A short, quick, one-handed motion enables immediate adjustment and application of this clamp.

Abstract: A laser processing fixture is formed to allow for facet processing of cleaved laser bars, either individually, or allowing for multiple bars to be processed simultaneously. The fixture holds the bars at a precisely-controlled distance with respect to a predefined reference plane, and holds the bars rigidly enough so as to minimize the possibility of vibration, but not so forcefully as to cause damage. The fixture comprises a fixed jaw and a movable jaw, with a pair of spaced-apart support members extending between the jaws. One or more laser bars may then be positioned between the jaws such that the front and rear facets will be exposed above and below the jaws. Therefore, each facet may be processed without unloading and re-loading the bars in the fixture. The support members, which may comprise a pair of wires, are spaced a sufficient distance so as to be disposed beyond the location of any active device region.
