Abstract: ABSTRACT OF THE DISCLOSURE          Finely divided borides, carbides, and nitrides of metals of Groups III-VI of the Periodic Table, formed by reacting vaporous metal halide and a boron, carbon, or nitrogen source reactant at high temper-atures, e.g., 1500°C., are separated from gaseous reactor effluent streamat temperatures between about 200°C. and 1500°C. with the use of a porous sintered filter.  By separating the finely divided product from the ef-fluent stream before the stream cools to below about 200°C., adsorption of impurities, e.g., unreacted metal halide or metal subhalides, on the product is reduced.  The use of a filter, e.g., a porous sintered filter, avoids the size classification of product which may result when cyclones and a bag filter are used to collect product.

Abstract: S. F. Valdes 3 PSEUDO-NOISE RADAR SYSTEM                 ABSTRACT OF THE DISCLOSURE A pseudo-noise radar system in which a maximal length binary pulse code of amplitude zero or A amplitude modulates a carrier wave and reverses the phase thereof 180 degrees in synchronism. Either one of the amplitude modulated or phase reversed waves is transmitted. The received wave is then passed through a multiplicative mixer that receives the other wave as an input. The mixer output is then effectively   when correlated and effectively zero when phase shifted one bit to one bit less than a word, where L is the word length. Signals not correlated are thus attenuated to an extreme degree. The above-described pseudo-noise radar system may be used with any other conventional equipment for fire control, missile range and/or velocity tracking or otherwise.

Abstract: ABSTRACT OF THE DISCLOSURE An inflatable bag comprising a peripheral side wall having a plurality of inflatable cells of flexible sheet material surrounding a storage cavity, and end walls to enclose each opposite end of the cavity, which end walls similarly include an inflatable cell of flexible sheet material. An opening is provided for entrance into the storage cavity, which opening includes means to open and close such as by means of a zipper. Air valves are provided for inflating and deflating the inflatable cells of the peripheral side wall and the inflatable cells of each end wall. When the inflatable cells of the peripheral side wall are inflated with air, the rigidity of the peripheral side wall increases to support the peripheral wall at points around the periphery which are spaced apart from the longitudinal axis of the storage cavity. The cells of the end wall are similarly inflated to provide rigidity and support for each end wall. When so inflated, a large storage cavity is formed and the cells of the side and end walls inflated with air provide insulation for the storage cavity.  When deflated, the bag may be folded into a compact unit for storage in a minimum of space.

Abstract: ABSTRACT     Dielectric receptor sheets which are transported seriatim from a tray into the gas-filled interelectrode gap of an ionography imaging chamber are arrested ahead of the chamber, and a corona is moved along each arrested sheet to apply a uniform electrostatic charge to or to neutralize the electrostatic charge of the arrested sheet.  Each arrested sheet whose charge is influenced by the corona is attracted by suction to the concave side of an arcuate guide. The corona is mounted on a carrier which is pivotable about an axis including the center of curvature of the concave side of the guide.          The carrier further supports a pivotable retainer which moves the central portions of the leaders of successive sheets against the concave side of the guide if the leaders exhibit the tendency to bend or bulge away from the concave side.  The marginal portions of sheets which are advanced along the guide extend into arcuate channels which flank the concave side.  The treatment by the corona can serve to destroy non-uniform positive or negative charges or to apply a uniform underground potential.

Abstract: ABSTRACT OF THE DISCLOSURE A syllabic compander uses logarithmic chains in both the compressor and expander.  The logarithmic chains are each constructed of a logarithmic amplifier, a scaler, and an anti-logarithmic amplifier or their equivalents.  The output of a logarithmic chain is equal to the input raised to a power determined by the scale factor of the scaler,  A logarithmic chain is used with a multiplier and an average value circuit to implement equations of the form   where ui is the input to the compressor or expander, u0 is the output of the compressor or expander, ? is the rms (or pseudo-rms) value of ui or u0 averaged over the time of one syllable, K is a constant, and a is the scale factor which is a function of the compression or expansion rate.  Since the scale factor a may be easily adjusted, the compander permits flexibility in changing the compression and expansion rates.
