Abstract: Abstract of the Disclosure Control of a fractionation column is accomplished by manipulating the flow rate of the external reflux in response to a calculation of the internal reflux flow rate to maintain the actual flow rate of the internal reflux at a substantially constant, desired value. An improved method for calculating the internal reflux flow rate when the heats of vaporization of the external and internal reflux are different utilizes a constant, repre-sentative of the heat of vaporization of the external reflux divided by the heat of vaporization of the internal reflux, to obtain an accurate calcula-tion of the internal reflux flow rate. Greater accuracy in the calculation yields improved control of the fractionation column. Alternatively, the constant, representative of the heat of vaporization of the external reflux divided by the heat of vaporization of the internal reflux, may be utilized to calculate the required flow rate of the external reflux necessary to maintain some desired internal reflux flow rate. Again, use of the described constant provides greater accuracy in the calculation and yields improved control of the fractionation column.

Abstract: Abstract of the Disclosure A process for producing thermally isolated monolithic semiconductor die and die produced by the process, plus improved apparatus using the die are disclosed.  The process generally comprises the steps of: forming a desired semi-conductor component or circuit in a semiconductor wafer (preferably a silicon wafer of <100> crystal orientation) having a protective layer (SiO2) one surface; forming platinum silicide contact windows in said protective layer where external connections to the semiconductor component or circuit are necessary; forming support leads of a layer of adhesive material (which also may have resistive properties, such as nichrome) and a layer of a structurally strong metal of high electrical conductivity and low thermal conductivity (preferably 304 stainless steel) along predetermined paths extending  outwardly toward the edge of the diefrom said contact windows; simultaneously with the forming of the adhesive layerof said leads, forming one or more thin film resistors in predetermined regions of said die atop said SiO2 protective layer, if desired; removing said SiO2 protective layer from a region defined by said support leads, an island or islands in which said semiconductor component or circuit and said resistors are formed and a surrounding frame; and, removing said silicon from the region between said island or islands and said frame.  The resulting semiconductor die comprises a frame surrounding one or more islands in which semiconductor components or circuits are formed, and which support resistors, if included.  The islands are entirely supported by the support leads extending between the frame and the islands.  In addition to providing support, the support leads also provide for electrical connection to the semiconductor components or circuits and to the resistors.  The semiconductor die may be mounted in a package that also forms part of the invention.  The package includes a ceramic substrate having an aperture in its center and alignment mesas and ridges on one surface.  The ceramic substrate is formed so as to be mounted on the metal header of a conventional semiconductor canister housing.  Depending upon their specific nature the resulting die are useful in and/or improve a variety of electrical apparatus.  They are particularly useful as the dual RMS sensor element of an RMS converter.  They can also be formed so as to be useful as radiation sensors.  Or, they can be formed so as to provide a thermal platform whose temperature is controlled and stabilized at a predetermined value.  All ofthese dies and the improved circuits resulting from their use also form part of the invention.

Abstract: ABSTRACT      A fireplace heating and cooling system is disclosed which heats air in a forced air heating system and heats water for a circulating hot water heating system or for hot top water when combustion occurs in the fireplace and alternately will cool the air in a central, forced air system by circulating water cooled by a heat sink, through heat exchangers.  A water reservoir is mounted on top of a fireplace firebox, having a central passage formed therethrough communicating with the throat of the firebox for absorbing heat from the combustion gases to heat water stored in the reservoir.  A valve means selectively connects the water reservoir to a pressurized water supply, with an outlet to a circulating hot water heating system or to hot water taps. An air plenum is formed around the reservoir for circulating air from the ambient, across the reservoir to transfer heat between the water and the air.  A heat exchanging element is connected to a heat sink such as subterranean soil, through which water is circulated by means of a pump and is selectively connected by the valve means to the water reservoir.  After combustion has occurred in the fireplace, air can be warmed in the plenum for space heating and the water in the reservoir can be warmed for circulating hot water heating or for hot tap water when the valve means connects the pressurized water supply to the reservoir.  Alternately, air can be cooled by circulating it through the plenum when the valve means connects the reservoir to the water circulating through the heat sink.  In this manner, the system which is used as a heater in conjunction with the fireplace in the winter time, may also be used as an air condition-ing cooler in the summertime.

Abstract: ABSTRACT      A female contact has at least one contact arm with an out-wardly diverging tip end for guiding the tip of a male blade in-serted into the contact.  A contact arm abutment is mounted on a contact chamber sidewall and projects inwardly into the chamber.          The abutment is aligned with an elongated contact arm of the female contact and is spaced outwardly from that arm to set the limit of acceptable outward contact arm deflection.  A portion of the contact arm extending rearwardly from the diverging tip end is channeled to allow this end to clear the abutment when the contact is inserted longitudinally into the chamber from the rearward end thereof.  The abutment limits outward displace-ment of the contact arm to prevent the overstressing of the arm by an engaging male blade and in a preferred embodiment, is formed as a unitary part of the pocket sidewall.

Abstract: CONTROL METHOD AND SYSTEM FOR A HIGH VOLTAGE DIRECT  CURRENT SYSTEM          ABSTRACT OF THE DISCLOSURE            In an HVDC system, two converter stations, each of which has two converters to operate as a rectifier or an inverter and are connected in cascade, are connected through a d.c. power transmission line to each other and are connected to respective a.c. power sources through the a.c. power trans-mission lines.  Each converter is controlled depending on the difference between a current reference for the HVDC system and the actual current flowing in the HVDC system when the converter operates as a rectifier, and is controlled depending on the output of the constant margin angle control circuit when the converter operates as an inverter.  When the converter operation condition is changed, i.e. another converter operates in addition to the converters already in operation, or the direction of power transmission in the HVDC system is changed, the current reference for the HVDC system is reduced depending on the d.c. voltage for a predetermined period.  This provides an improved control method which can suppress the increase of reactive power required by the converters when the operation mode of the HVDC system is changed.

Exceeding such trip boundaries in a direction from the inside towards the outside can be utilized as a fault criterion for producing a trip signal.  With suitable trip boundaries, at least in-clined in sections towards the coordinate axes owing to the aforementioned dependency of the comparison threshold values, which trip boundaries also may be curved, and arranged in spaced relationship from the coordinate-null point in the four quadrants of the surge signal-coordinate system there is realized a rapid fault detection which is comparatively foolproof against faulty tripping and by determining the quadrants where there occurs the initial exceeding of the threshold value, there likewise can be realized an equally rapid and positive fault-direction detection.     .
