Granted: 1993-06-29
Abstract: ABSTRACT      A method of forming a carbothermally reduced powder of nitrides or carbides is disclosed.  The product powder consists principally of unagglomerated particles and is formed by providing a collection of precursor particles in colloidal dispersion, adding to the dispersion a polymerizable monomer, polymerizing the monomer to matrix the precursor particles in discrete, well dispersed positions and carbothermally reducing the particles followed by removing excess carbon by burning.          The polymer matrix acts as an agglomerate-inhibiting carbon source during carbothermal reduction.

Abstract: Abstract Mechanical drilling aid A mechanical drilling aid serves for guiding a drilling tool (42) when drilling a bore into an object, in particular into a wall (39), eccentrically to an existing faulty bore (20), when the cross-sections of the faulty bore (20) and the correct bore intersect each other or extend immediately adjacent each other. In order to ensure simple and exact guiding of the drill during the drilling operation, the mechanical drilling aid comprises a guide element (14) provided with a cylindrical opening (25) for guiding the drilling tool (42). A rod-shaped part (16), which is capable of being introduced into the faulty bore (20) projects from the guide element (14) and can be applied against the inner wall (21) of the faulty bore (20), at least along one outer edge (18), the distance between the outer edge (18) of the rod-shaped part (16) and a longitudinal center axis of the cylindrical opening (25), measured across the center point of the cross-section of the faulty bore, being equal to the sum of the amount of eccentricity between the faulty bore and the bore, and the radius of the faulty bore (fig. 7).

Inventor: TURNER HOWARD WILLIAM
IPC: C08F10/02
Filed: 1996-04-16

Abstract: A catalyst is prepared by combining, in a suitable solvent or diluent, at least one first component consisting of a bis(cyclopentadienyl) derivative of a Group IV-B metal containing at least one ligand capable of reacting with a second component, which second component comprises a cation which will irreversibly react with at least one ligand in said first component and a stabilizing anion comprising a plurality of boron atoms which anion is bulky and stable to any reaction involving the cation of the second component and sufficiently labile to permit displacement by an olefin, diolefin, and/or acetylenically unsaturated monomer, and (b) maintaining the contacting in step (a) for a sufficient period of time to permit the cation of said second component to react with said ligand in said first component thereby forming an active catalyst either as a direct product or as a decomposition product thereof.  Many of the catalysts thus formed are stable and isolable and may be recovered and stored.  The catalysts may be preformed and then used to polymerize olefins or the catalysts may be formed in situ during polymerization by adding the separate components to the polymerization reaction. The catalyst will be formed when the two components are combined at a temperature within the range from about -100°C to about 300°C.  The catalysts thus prepared afford better control of polymer molecular weight and are not subject to equilibrium reversal.  The catalysts thus produced are also less pyrophoric than the more conventional Ziegler-Natta olefin polymerization catalysts.

The barium compound is added to the phosphoric acid to be purified, and the resulting mixture is fed to the top of the extraction installation, in which the organic solvent phase is dispersed in the aqueous phase. The sulfuric acid is led in counter-current fashion to the phosphoric acid by adding it to one of the stages n=4 to at most n-1.

Abstract: In a method of producing a substantially U-shaped guide rail in a groove formed in the respective window frame portion (23) of a slidably hinged window, a web-shaped elastic material which in the transverse direction is substantially flat, is formed into U-shape by bending the side sections (16, 18) relative to each other, said side sections being defined in the web-shaped material by longitudinal weakening grooves or weakening lines extending in parallel to one another and preferably formed in the side of the web material constituting the front face of the rail, and the material which is bent into U-shape is inserted in the groove of the associated window frame portion (23) in which it is secured by suitable means.     To produce the guide rail, use is made of a blank of an elastic web material which is made by extrusion and stored in wound-up state. The lateral faces of the weakening grooves make an angle of slightly less than 90° with each other, such that the cross-section of the grooves is completely closed as the side sections (16, 18) are bent in order to form the guide rail.

A splitter splits the optical WDM signal correspondingly to the wave-lengths .lambda.i to generate optical wavelength-corresponding WDM signals Wi.  Wavelength extracting circuits extract optical FSK     signals Fj (j = 1 to N) pertaining to wavelengths .lambda.j, to which the wavelengths .lambda.i are to be switched, from the optical wavelength-corresponding WDM signals Wi to generate optical amplitude-shift keying (ASK) signals Aj pertaining to the wavelengths .lambda.j to be switched to.  Wavelength switches switch the optical ASK signals Aj to second optical FSK sig-nals Fi corresponding to the wavelengths .lambda.i.  A wavelength multiplexer wavelength-multiplexes the second optical FSK signals Fi into an optical switched WDM signal.

Title: Spread spectrum signal detector
Inventor: CANTWELL ROBERT H
IPC: H04B1/707
Filed: 1990-02-20
Granted: 2001-01-16
Abstract: A spread spectrum signal detector for sampling a modulated carrier employing a zero-crossing detection means having two independent control loops, a first loop for a zero-mean threshold control and a second loop for AGC control. An IF sampler quantizes the received spread spectrum signals at IF and provides high immunity to interference or jamming. The IF signal is sampled at a number of quarter cycle intervals to allow sampling in sequence of the in-phase (I) and quadrature-phase (Q) components. The output of the IF sampler is two bits, a sign bit and a magnitude bit. The zero-mean threshold control loop using only the sign bit of the I and Q samples sets a threshold level (T0) to detect the zero-crossings of a received waveform. Two magnitude threshold levels are set at fixed offsets from the T0 threshold level. A normalized statistical accumulator using the magnitude bits of the I and Q samples determines the AGC control level for a fixed percentage of outside threshold crossings of the most significant magnitude bit. The I and Q samples are aligned in time, and every other pair of I and Q samples are inverted for digital demodulation of the IF samples to baseband. The baseband samples are provided to a signal processor for generating range and range rate information.
