Abstract: The containment of biohazardous substances, which may exist in the streams of sample material that are being separated in air into droplets in a testing chamber of equipment, such as cell sorters and cytofluorometers, is attained by subjecting the testing chamber to negative air pressure, so that inward air flow at the open face of the chamber is sufficient to inhibit biohazardous substances from exiting out from the face of the chamber.

The air stagnation region is formed by interposing an air diverter between the sample streams and the air flow exhaust port at the rear of the testing chamber.

Abstract: This is a new point-detonating fuze for spin-stabilized munitions. The fuze has three modules housed in a two-piece body, designed to optimize the penetration capability and to adjust the weight of the fuze. The upper body carries the point-detonating module which has a double-initiation feature, designed to function on impact against the target but preventing detonation on impact against rain droplets and against the foliage of wooded areas. The explosion, initiated at the top of the point-detonating module, is propagated by a mild-detonating fuze, first axially inside the shaft of the point-detonating module, then axially through the time-delay module, to reach the detonator in the safing-and-arming module. The point-detonating module acts as a selector designed to provide either a super-quick function or a time-delay function with several time-delay options. The desired choice is made by rotating the moving portion of the time-delay module to one of several pre-indexed positions.

Abstract: An improved railway car wheelset having a novel wheel configuration that permits greatly improved performance on existing and improved track. This means that substantially higher rolling speeds can be achieved without loss of stability and while maintaining the ability of the wheelset to self center and self steer.

This wheel configuration operates to reduce the magnitude of the effects that occur when disturbances cause the wheelset to deviate from centered position on the track.

Abstract: The present invention advantageously uses a composition which includes iron-containing waste materials to dispose of the toxic and troublesome substances, polybrominated biphenyls (PBB). First, waste materials from the conversion of iron ore to pig iron or steel combine with a reducing metal, such as aluminum or magnesium, and a small portion of a mineral acid to form a reaction mixture which gives a heat output superior to many conventional fuels and at a very high temperature. Then, this composition is heated to a reaction temperature with pure PBB or items contaminated with PBB to thereby chemically break down the PBB.
