Abstract: The velocity of a fluid in a positive or negative direction is measured by se of a thermistor in a feedback circuit. The temperature of a flow thermistor is balanced with the temperature of a reference thermistor by sensing temperature through resistance by way of its voltage and adding power until the flow thermistor is at the same temperature as the reference thermistor. The ratio of reference power used as compared to flow power is indicative of the fluid's speed. Power is added by sending a signal of varying frequency to the flow thermistor; the reference thermistor is powered by a constant frequency signal. Power is measured by comparing the frequencies of the reference signal to the flow signal. Fluid direction is measured by placing a direction thermistor on either side of the flow thermistor, measuring the temperature of each direction thermistor, the cooler thermistor being upstream of the flow thermistor.

Abstract: The present invention is a process of degrading 1,4-dibenz-oxazepine with a icroorganism enzymatically capable of converting the 1,4-dibenz-oxazepine into at least o-nitrophenol which is further converted to catechol. The present invention is preferably carried out using a strain of Alcaligenes denitrificans denitrificans. Additional related compounds which can be degraded with Alcaligenes denitrificans denitrificans include: o-nitrophenol, catechol, and 3-methylcatechol.

Abstract: Apparatus and a method for producing submicron and smaller metal alloy pacles using a main chamber having a longitudinal axis and a feeder for introducing a quantity of molten alloy under pulsed gas pressure in a direction generally radial to the axis. The feeder has a gas stream for forming metal droplets from said alloy. A gas accelerator directs axially flowing gas against the droplets from the feeder in the chamber. The accelerator directs the droplets in an axial direction to a substrate located along the axis and in the direction of flow from the accelerator to receive the droplets at a predetermined distance from the feeder, whereby the particles are produced.

Abstract: A millimeter wave screening cloud is formed comprised of an aerosol of fine ibers of a carbon composition, in which the particles are of micron diameter and millimeter length. The cloud is formed by aerosolizing a compact mass of carbon composition fibers through the action of explosively bursting such compact mass in the atmosphere at the desired cloud location.

Abstract: An improvement when 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane is preed by nitrolysis of 1,3,5,7-tetraacyl-1,3,5,7-tetraazaceyloctane with a solution of nitric acid and nitrogen pentoxide or phosphorous pentoxide. This improved process herein before set forth produces 99% yield and purity of product.

Abstract: A smoke forming composition is provided suitable for being explosively dirsed in projectiles, bombs, grenades and the like munitions which is composed of a mixture of finely divided solid particles of smoke forming material and a liquid component in an amount sufficient to densify the solid particles of smoke forming materials to increase the bulk density thereof as well as reducing the danger of ignition or "flashing" of the smoke forming materials when explosively dispersed.

Abstract: Tungsten heavy alloys comprising by weight from about 80 to about 100% tuten and from about 0 to about 20% of one or more heavy alloying metals are produced by introducing powders of tungsten and the alloying metals into a thermal spray plasma gun, melting the powders in the hot zone of the gun to form a molten alloy and then spraying the molten alloy in droplet form into a collecting chamber where the droplets are solidified, and the resultant alloy in powdered form is collected. The powdered alloy can be further mixed with powdered copper, iron, nickel, cobalt or tantalum and compacted by dynamic or explosive compaction to form a near full density material. Full density materials are produced by further thermomechanical processing of the compact.

Abstract: This invention describes a process for producing copper alloys by rapid sdification in order to improve their strength and thermal stability after being exposed to elevated temperatures. The method used to rapidly solidify the molten alloy is either by use of a high pressure non-oxidizing gas spray to atomize the molten alloy into a powder or to pour the molten alloy onto a rotating wheel to form a ribbon which is then attrited into powder. The powder is canned, compacted to full density and cold worked to the desired shape.
