Abstract: 47,479 VOLTAGE REGULATOR UTILIZING A STATIC VAR GENERATOR WITH HALF PERIOD AVERAGING AND   SATURATING TYPE FIRING ANGLE CONTROL      ABSTRACT OF THE DISCLOSURE A voltage regulator is taught for maintaining the terminal voltage of a three phase transmission line at a fixed reference value.  The voltage regulator system utilizes the reactance of the transmission line in conjunction with reactive current from a VAR generator to compensate for the voltage effect of line current as it flows through the line reactance.  me VAR generator is of the parallel capacitor-inductor type where the inductor is controlled by a thyristor switch.  The conduction of the thyristor is controlled by utilizing a control system which generates an error signal based on the half period average of line voltage. The error signal is converted to a signal which is proportional to flux linkages by an integrator and then compared with the integral of the voltage signal for determining the conduc-tion angle of the thyristor switches.

Abstract: ABSTRACT    A monolithic digital/analog converter comprising N current sources provides weighted currents to associated switching circuits which steer the weighted currents either to an output summing line or to a dump line under control of the bits of the word to be converted.  Set of the pairs comprising a current source and a switching circuit are divided into two groups of distinct structures.  The first group comprises n pairs and the second one comprises m pairs with N = n+m. The continuity between the currents provided by the sources of the two groups and their scaling are assured by three auxiliary sources, namely a master source for monitoring the n high order currents, an high order image source and a master source for monitoring the m low order currents, and two scaling circuits, namely a high order current scaling circuit and a low current scaling circuit for controlling the value of the current provided by the low order current monitoring source from the current provided by the high order image source.  In addition to the bit controls, the converter has two controls called "Force" and "Inhibit".  The "Force" control forces the currents provided by all the sources into the output summing line whatever the converter input bit pattern.  The "Inhibit" control causes the currents provided by all the sources to be sent into the dump line.

Abstract: MAST LEVELING AND SUPPORT APPARATUS           Abstract of the Disclosure.  A box-like platform having a mast leveling hinge support anchored thereto and a mast struc-ture pivotally attached to the upper end of the hinge support is pivotally attached at one of its ends to an elongated skid unit. The opposite end of the platform is arranged to be raised or lowered by a pair of jacking assemblies connected to the skid unit to effect leveling of the platform.  A hydraulic ram having one end connected to the mast and the other end connected to a ram beam supported by a lower extension of the platform enables the mast to be raised to its upright position.  By utilizing the ram in conjunction with the leveling characteristic of the plat-form, the mast assembly can thus be raised to a level and stable condition without the skid unit being perfectly level with respect to the earth's surface.  The apparatus permits proper alignment of the mast to the center line of the well to compensate for settlement of the skid unit on an unlevel foundation.                             -1a-

Abstract: ABSTRACT OF THE DISCLOSURE Fluoridic spent and waste materials, such as are generated in electrolytic aluminum reduction systems, are pyrohydrolyzed in a fluidized bed reactor. For fluidiza-tion of these materials, as well as for the combustion of carbon present in the materials, an 02-containing gas Stream containing at least about 90% by volume 02, is employed. This results in the generation of an HF-contain-ing offgas of significantly increased HF level, which can be employed for the manufacture of an AlF3 product of at least about 85% by weight AlF3 content from hydrated alumina. The offgas having the increased HF content can also be employed for the production of highly concentrated HF acid with significantly lower energy requirement needed for concentration than in conventional systems.

Abstract: ABSTRACT OF THE DISCLOSURE.      To increase the response speed and sensitivity, while providing higher output voltages and permitting higher loading of the electrodes of gas sensors, particularly exhaust gas sensors to determine the transition of exhaust gases from internal combustion engines between reducing and oxidizing state, the sintering activity of the electrode which, typically, a cermet electrode, is selected to be less than that of the solid electrolyte body so that the resulting pore structure will be more open than that of the solid electrolyte body.  The electrodes, essentially, consist of finely divided ceramic material, such as zirconium oxide, and finely divided electron conductive material such as platinum.  On the pre-sintered solid electrolyte body, a mixture of the ceramic and the electron conductive material is applied in which the ceramic of the lattice support structure for the cermet electrode is less sinter-active than the ceramic of the solid electrolyte body, resulting in the improved pore structure of the cermet electrode layer.
