Abstract: A system, particularly suited for after market applications, for enclosing an overhead guard with window and prehung door assemblies. The window and door assemblies are arranged with portions that overlie outer surfaces of the guard and portions engageable with inner surfaces of the guard to retain the respective assemblies in place on the guard. The retaining structure of each of the assemblies extends through original vision or ingress/egress openings in the guard so that installation is simplified and structural alteration of the guard is avoided.

Abstract: The invention relates to a safe mechanism for resistance to drilling, by use of a door mounted crankshaft mechanism. The crankshaft includes a shoulder which transfers force to the safe door rather than transmitting it to other lock mechanism components. A crank plate attached to the crankshaft rotates from an open position to a locking position, and by rotation moves a link arm with attached locking pins laterally into engagement with the doorframe. A re-locker device locks both the crank plate and the link arm in place to make entry more difficult.

Abstract: A powder metal main bearing cap has integral dowels at its adjoining face around bolt holes and tooth projections surrounding the dowels. The dowels are force fit into counterbores in the engine block and the teeth bite into the metal of the block around the bolt holes to inhibit fretting wear. Elongated bolt holes can be formed in the main bearing cap to accommodate a splayed joint, with the bolt head supporting face of the cap at an oblique angle to the hole. The bearing cap can be first pressed into the engine block so as to assure indentation by the teeth and insertion of the dowels, followed by bolting.

Abstract: A container device with an adjustable volume is provided for holding and immobilizing solder spheres used in manufacturing printed circuit boards and other electronic assemblies. The container device includes a hollow containing portion having a first terminal end and a second terminal end with a side wall connecting the first and second terminal ends and a removable sealing mechanism connected to the first terminal end. An adjustable piston is positioned within the containing portion having a length and a width such that when the piston is inserted into the containing portion of the container device, the piston exerts a sufficient pressure against the side wall of the containing portion to rigidly position the piston within the container device. The pressure exerted by the piston forms a seal between the piston and the side wall of the containing portion, thereby preventing solder spheres contained therein from slipping between the piston and the side wall.

Abstract: The present invention provides a method for purifying ruthenium sources to obtain high purity ruthenium metal without the need for high temperature processing, expensive reagents, complex series of wet processes, or expensive equipment. According to the present invention, a gas stream including ozone (O3) is brought into contact with a ruthenium source, such as a commercial ruthenium metal sponge, in one or more reaction vessels. The ozone reacts with the ruthenium present in the ruthenium source to form ruthenium tetraoxide (RuO4), a compound that is a gas at the reaction conditions. The ruthenium tetraoxide, along with unreacted ozone and the remainder of the gas stream is then fed into a collection vessel where a major portion of the gaseous ruthenium tetraoxide is thermally reduced to form ruthenium dioxide (RuO2) deposits within the collection vessel.

The lid insert forms a mechanical seal which immobilizes the solder spheres until the lid insert is removed from the containing device.

Abstract: Copper-containing surfaces, such as a copper surface for use in an electrical circuit, are protected by the provision of a bismuth metal coating immersion-plated from a moderately to strongly acidic plating bath. The plating bath preferably contains dissolved bismuth, halide, and a sulfur-containing ligand as a complexing agent that promotes adhesion of the bismuth coating. The bath may be formed from a concentrate system combined with water. The concentrate system may be a two-component system having an acidic first component containing the bismuth, halide, and sulfur-containing ligand, and an alkaline second component containing an additional complexing agent (e.g., EDTA salt). Tarnish resistance of the plated bismuth can be improved by the application of an alkaline composition to neutralize residual acid. Plating thickness can be enhanced by pre-cleaning the surface to be plated with a pre-cleaner containing nitric acid.
