Title: Gain control circuitry for quadrature amplitude modulation demodulator
Inventor: YAMAMOTO TAKESHI
IPC: H04L27/38
Filed: 1992-02-26
Abstract: In a QAM (quadrature amplitude modulation) demodulator, gain-controlled amplifiers are provided respectively for the in-phase and quadrature channel baseband components of the signal, and a set of data and error signals is recovered from the output of each gain-controlled amplifier.  To determine the location of the signal point of each channel component, the QAM signal constellation is divided along the axis of the channel into two outermost regions A, an innermost region B and two intermediate regions C, and further divided along the axis of the channel into two outer regions E and an inner region D therebetween.  In response to each set of data and error signals, the location of the signal point of each baseband component is determined with respect to the regions A, B and C to produce a first logical output signal and with respect to the regions D and E to produce a second logical output signal.  Each of the gain-controlled amplifiers is controlled in response to the first logical output signal derived from one channel and the second logical output signal derived from the other channel.

Title: Circulating bed cofeed conversion reactor and method for converting light hydrocarbons to olefins, gasoline and methanol
Inventor: BAINS CHARANJIT S
IPC: C07C29/152
Filed: 1991-02-12
Abstract: The invention provides a method of converting light hydrocarbons to olefins, gasoline and methanol. In the first stage, a gas containing one or more light hydrocarbons is synthesized to higher hydrocarbons including raw gasoline. However, at commercially acceptable selectivities using currently available catalyst, a majority of the light hydrocarbons remain unsynthesized. In addition, the synthesis produces significant quantities of carbon dioxide and some carbon monoxide. In this method the unsynthesized light hydrocarbons and the oxides of carbon are used to produce methanol, which can be used for several purposes including gasoline or ethylene synthesis.

Abstract: A domestic composter of molded plastic has an upwardly tapered body comprising an upper and a lower half,  with tongue and socket connectors such that the two halves may be firmly assembled together or separated without the use of tools.   The upper half fits readily within the lower half, permitting transportation of the composter within a standard size automobile.  The tapered construction enables multiples of the respective body portions to be nested, for economical bulk transportation.   An access door is provided,  having securing lugs that may be padlocked, and the removable lid of the composter may be  rotated into a selectively variable position  that  precludes  removal  and  affords  ventilation control.  The lid may be readily removed, or may be elective-ly opened to a partial-access position for one-handed depos-iting of waste therein.  A comprehensive vent system allows controlled cooling and ventilation while precluding access even to small animals such as mice.  Screw-down earth anchors may be used to anchor the composter to the ground, or over a plain base plate.

Title: Microwave, rf, or ac/dc discharge assisted flame deposition of cvd diamond
Inventor: ANTHONY THOMAS R
IPC: C23C16/513

Abstract: MICROWAVE. RF. AC/DC DISCHARGE ASSISTED    FLAME DEPOSITION OF CVD DIAMOND                         Abstract of the Disclosure Broadly, the present invention is directed to improving a chemical vapor phase deposition (CVD) method for synthesis of diamond wherein a hydrocarbon/hydrogen gaseous mixture is subjected to a combustion flame in the presence of oxygen to at least partially decompose the gaseous mixture to form CVD diamond. The improvement in process comprises subjecting said combustion flame to one or more of dielectric heating, d.c. discharge, or ac. discharge. Dielectric heating can be accomplished by subjecting the combustion flame to microwave (MW) frequency discharge or radiofrequency (RF) discharge. By superimposing dielectric heating or d.c./ac. discharge plasma generation on combustion flame process, the carbon utilization rate of the combustion flame process should improve substantially. As noted above, given the low carbon utilization rate for combustion flame techniques already, small percentage improvements in the carbonutilization rates translate into substantial cost savings in generation of CVD diamond by such combustion flame technique.
