Abstract: ABSTRACT OF THE DISCLOSURE         An electronic kWh meter is disclosed which measures electrical energy consumed in an electrical system.  A current transformer generates an analog voltage which is proportional to a current in the electrical system.  An operational amplifier has an input resistor connected across the load impedance of the electrical system and has a feedback resistor connected across the input and output of the amplifier.  The input resis-tance of the amplifier is very small compared to the resistance of the input resistor to thereby virtually isolate the operational amplifier from the electrical system.  The operational amplifier generates an output signal which is proportional to the voltage across the load impedance in the electrical system.  The in-phase components of the voltage and current are multi-plied to provide a signal which is proportional to the instantaneous power in the system.  This signal is converted to a pulse train wherein each pulse represents a quantized amount of energy consumed within the system.          The pulse train is accumulated, recorded, and a display is provided for indicating the energy being consumed within the system.  Both single phase and polyphase embodiments of the meter are described.

Abstract: MACHINE TOOL                     ABSTRACT OF THE DISCLOSURE An improved machine tool includes an extendible ram or tool support arm.  As the ram is extended, the outer end portion of the ram deflects downwardly under the influence of gravity.  To compensate for the deflection of the ram, the angular orientation of the ram relative to upwardly extending tracks is changed to raise the outer end portion of the ram.          This is accomplished by means of gibs or deflection compensation cams which are moved to rotate a carriage or saddle on which the ram is mounted.  The extent of deflection of the ram varies as a function of the distance which it extends outwardly from the carriage.  Therefore it is necessary to store data indicative of the deflection of the ram at various degrees of extension and to adjust the orientation of the ram in accordance with this data as the ram is extended.  The data indicating the extent to which the ram deflects is stored by means of a cam mounted on the carriage.          The cam is read by a transducer which moves with the ram.  The extent of deflection of a second tool support arm or boring bar carried by the ram varies as a function of the extent to which the boring bar extends outwardly from the ram.          Accordingly, a cam connected with the ram is read by a transducer connected with the boring bar to determine the compensation for deflection of the boring bar relative to the ram.  Relatively heavy right angle drive attachments may be utilized in association with the ram.  Therefore a third cam is provided to store data indicative of the deflection which results from mounting of the attachment on the outer end of the ram.

Abstract: DISCHARGE ARRANGEMENT FOR            AN AXIAL FLOW ROTARY SEPARATOR              Abstract of the Disclosure In an axial flow rotary separator, a rotor and a cylindrical housing are provided with material control elements so that, as is conventional, when the rotor is rotated, crop material in the annular space between rotor and housing is propelled downstream in a generally helical path.  The lower portion of the downstream end of the wall of the cylindrical housing is notched or cut back to facilitate discharge of straw from the housing in a generally downward and rearward direction.  The relief or notching of the lower portion of the cylindrical housing is defined by an "exit" edge extending helically upstream from the downstream extremity or edge of the cylindrical portion of the housing wall, from a point somewhat below the axis of the rotor and extending (circum-ferentially) around the lower half of the housing and up to approximately the level of the rotor axis on the other side of the housing, and by a horizontal "outlet" edge extending from the downstream extremity of the cylindrical wall portion upstream to meet the upstream end of the helical edge.  The "notch" so formed is triangular shaped in its flat development.  The transverse opening defined by the downstream end of the cylindrical housing may be left open or may be partially closed by a transverse bulkhead extending over an upper portion of the opening so as to limit the axially rearward or downstream movement of the dis-charged material.  To facilitate the discharge and flow of mate rial, a crop material cutter is optionally provided close to the junction between the horizontal outlet and helical exit edges of the discharge opening or notch in the housing wall.
