Abstract: 28.8.1978                                       PHB 32605 ABSTRACT Linear amplifier.              High-gain linear amplifier comprising n-MOS transistors having a load in the form of two depletion mode transistors connected in cascode. The variation of thres-hold voltage VT with back bias VSB of the cascode load transistors is compensated by applying a voltage in the opposite manner to the VT-VsB variation.           A way of producing the compensating voltage is to connect an enhancement mode transistor in cascode with a depletion mode transistor. The drain of the enhancement transistor is connected to both the source of the deple-tion transistor and the common connection of their gates which are connected to the gates of the load transistors In fabricating the amplifier as an integrated circuit, the amplifier may be a long tail pair amplifier.

Abstract: FORAGE HARVESTER RECUTTER SCREEN     Abstract of the Disclosure A forage harvester has a cutterhead housing with a rotary reel type cutterhead mounted therein, the cutterhead having a plurality of knives parallel to the cutterhead axis at the cutter-head periphery, the knife edges generating a cylinder as the cutterhead rotates.  The cutterhead reduces crop material that is fed into the housing and discharges the reduced material through a discharge opening to a conveying system that conveys the crop material to a crop-receiving vehicle.  Removably mounted over the discharge opening is a recutter screen that has an arcuate shape generally concentric with and adjacent to the cutterhead periph-ery and a plurality of elongated apertures, each aperture having parallel longitudinal edges that extend diagonally relative to the knife cutting edges.  The apertures are arranged in two transversely extending rows with the apertures in one row being inclined in one direction from the vertical and the apertures in the adjacent row being inclined in the opposite direction, the opposite angle of inclination of the apertures in the second row counteracting the tendency of the apertures in the first row to move the crop material impelled through the apertures in the direction of inclination.  Alternate screens are conventionally provided with different size apertures according to the fineness of cut desired, and the screens are removably mounted in a frame that is adjustable relative to the cutterhead to maintain the optimum minimum clearance between the cutterhead and the recutter screen.

Abstract: (U.S. 936,016) ABSTRACT OF THE DISCLOSURE           A control system for a multi-phase synchronous machine having a shaft driven at variable torque angle includes shaft angular position detectors that derive first and second output pulses respectively repre-senting a shaft angular displacement corresponding with each pole of the machine and a predetermined shaft angular displacement within each pole.  In response to a plurality of the second output pulses, a frequency locked loop derives a variable frequency pulse output. Individual pulses are selectively inserted and deleted from the vari-able frequency output to derive a variable phase pulse output repre-senting machine torque angle.  A triangle up/down counter responds to the variable phase output to derive a pulse output signal having a frequency that is a submultiple of the variable frequency output and a phase determined by the phase of the variable phase output. The time position of pulses of the first output and the up/down counter are compared to control the insertion and deletion of the individual pulses.  Eash phase of the machine is driven in response to the output signal of the triangle up/down counter.

Abstract: 90-HR-12784 - Gelbard et al ABSTRACT OF THE DISCLOSURE           The present invention relates to an air circulating and cooling arrangement for a refrigerator cabinet including a fresh food and freezer storage compartment.  A partition dividing the compart-ments includes a first wall defining the upper wall of fresh food compartment and a second wall defining the lower wall of the freezer compartment.  A divider element arranged intermediate the partition walls separates a first passage for circulating air through the fresh food compartment and a second passage for circulating air through the freezer compartment.  The evaporator is in heat exchange relation with a portion of the first passage so that air moving through the fresh food compartment contacts colder portions of the divider to remove moisture therefrom prior to passing through the evaporator.  The heat leakage from that portion of the divider in heat exchange relation with the evaporator conductively links the evaporator to the fresh food compartment.  In effect the present invention links the evaporator to the fresh food compartment conductively as well as convectively.
