Abstract: Cribbing apparatus for stabilizing a post-accident vehicle against unwanted shifting of the vehicle during a rescue operation in which a victim trapped in the vehicle is to be extricated from the vehicle includes cribbing blocks hinged together for pivotal movement to fill a space between the vehicle and the ground at the site of an accident. A wedge is inserted between the pivotally connected cribbing blocks for operating the cribbing apparatus without jolts and dislocations which otherwise could cause shifting and concomitant increased danger of injury to the victim, as well as to a rescuer. A hinge includes leaves and wings in U-shaped configurations which deter skewing of the cribbing blocks during pivotal movements. The cribbing blocks include grooves for reception of the wedge such that skewing or collapse of the wedge is deterred by virtue of the confined movement of the wedge within the grooves during operation of the cribbing apparatus.

Abstract: A method of functionalizing a diamond crystal comprises hydrogenating a diamond crystal, chlorinating the hydrogenated diamond crystal; and exposing the chlorinated diamond crystal to a metal precursor. The exposing step deposits a layer of metal on surfaces of the diamond crystals. The diamond crystal formed by the method possesses surface sites that form a strong bond with the layer of metal to prevent separation thereat, and the layer of metal form strong bonds to a matrix material, for example one of a vitreous and metallic matrix. The functionalized diamond crystal can be used in abrasive products.

Abstract: The present invention is a fluid dispensing fixed abrasive polishing pad CMP system and method that utilizes fixed abrasive components to remove a portion or entire layer of a wafer while dispensing a fluid without suspended abrasive particles onto the wafer surface. A fluid dispensing fixed abrasive polishing pad is pressed against a wafer surface while rotating and fixed abrasive component apply a frictional force that planarizes a wafer surface. The fluid dispensed by the fluid dispensing fixed abrasive polishing pad assist the fixed components achieve wafer planarization in numerous ways, including minimizing scratching of the wafer surface, chemically reacting with the wafer surface to soften it, and aiding in the removal of particulate contaminants. The fluid flow in the present invention is strong enough to remove the waste (e.g., reaction products, wafer shavings, particulate contaminants, etc.) from the surface of the wafer and the fixed abrasive polishing pad during the polishing process.

Abstract: A cylinder liner removal tool (11) is shown having a gripping portion (12) capable of expanding against the inner surface of the cylinder liner (14). The gripping portion (12) has a rod (26). Concentrically disposed about the rod (26) in trailing order is a stop (32), a plate (36), a cylindrical mandrel (38), a shoulder (42), a bearing (44), and a nut (40). The mandrel (38) is hollow having a recess (52). The shoulder (42) has a plug member (66) disposed within the recess (52). Torquing down upon the nut (40) compresses the mandrel (38) between a radially extending shelf member (62) of the shoulder (42) and the plate (36). The mandrel (38) thereby expands radially outward to frictionally grip the cylinder liner (14).
