Abstract: ABSTRACT OF THE DISCLOSURE           A video display system comprising a stress wave propagating means defining a viewing plane and including means for initiating the propagation of stress waves along the propagating means in a first scanning direction in the viewing plane.   A light emitting means is disposed to emit light along a scan line in a second scanning direction generally perpendicular to the first scanning direction.   The light emitting means is disposed in relation to the stress wave propagating means to emit light incident upon each of the stress wave propagated along the propagating means over the extent of the viewing plane in the first scanning direc-tion so that the emitted light interacts with the propagated stress waves over an entire scanning interval in the first scanning direction and so that the light emitted along the scan line in the second scanning direction is scanned in the first scanning direction over the  entire viewing plane by the stress waves.  The emitted light is selectively modulated in intensity by a video signal resulting in the display of an image in the viewing plane.   In one embodiment of the invention, the stress wave propagating means is trans-parent and the light emitting means is disposed to emit light through the propagating means.   A first sheet of transparent polarized material is disposed intermediate the propagating means and the light emitting means to linearly polarize light passing therethrough in a first polarization direction.   A second sheet of transparent polarized material is disposed in the path of light passing through the first sheet and propagating means and has a polarization axis disposed perpen-dicular to the polarization axis of the first sheet.     In another embodiment of the invention, the stress wave propagating means comprises a surface wave propagating medium and surface waves are propagated along a planar sur-face of the medium.  The surface of the medium along which surface waves are propagated is light reflective over at least the area of the viewing plane and the light emitting means is disposed to emit light parallel to the planar sur-face of the medium so that the emitted light strikes the propagated wave and is reflect away from the planar surface by the propagated surface waves. A color embodiment and a parallel output feature are also disclosed.

Abstract: GRAIN ACCELERATOR PRECLEANER                 ABSTRACT OF THE DISCLOSURE         The threshed material leaving the threshing cylinder of a grain harvester or combine is accelerated into a transverse air stream by a pair of rolls.  The rolls are disposed on parallel axes and are rotated at a relatively high speed in opposite directions whereby their confronting peripheries engage and accelerate the threshed material to a velocity substantially in excess of the speed at which such material would fall by gravity.  A wide band of relatively high speed air is directed transversely through the accelerated material to provide a precleaning of straw and chaff from the material normally passing to the grain separation or cleaning shoe section of the combine.  The grain in the accelerated material continues in a relatively straight line trajectory and the straw and chaff are separated from the grain by the transverse air stream.

Abstract: ABSTRACT OF THE DISCLOSURE       A gas-blast interrupter of the puffer type comprises a piston positively connected to the movable contact rod of the interrupter and means defining a pumping space at one side of the piston containing gas compressed by piston motion during an opening operation.  At the opposite side of the piston there is a working space in which compressed gas can act upon the piston to aid an opening operation.  A blast passage is provided through which gas from the pumping space can flow into the arcing region. An auxiliary passage affords communication between this blast passage and said working space.       Valve means effective during a low current interruption blocks flow through the auxiliary passage and allows free communication between the pumping space and the blast passage, whereby during a low current interruption, compressed gas from the pumping space can flow into the arcing region via the blast passage  The valve means is effective when pressure in the arcing region is high during high current interruptions: (i) to allow arcing products to flow through the auxiliary passage into the working space and (i.i.) to block free communication between the pumping space and the blast passage, thus decreasing contamination of gas in the pumping space and reducing pressure build-up therein.

Abstract: VACUUM CLEANER FILTER BAG CONDITION INDICATOR            ABSTRACT OF THE DISCLOSURE    A vacuum cleaner filter bag condition indicator that detects when the bag is substantially full and should be replaced.  The indicator includes a pressure responsive member having internal filter bag pressure applied to a small area of one side thereof and filter bag compartment pressure applied to the entire other side.  When the bag becomes substantially full the bag pressure increases and the increased pressure differential causes the pressure responsive member to move slightly to allow the filter bag pressure to act on the entire area of the one side.  The pressure responsive means thereafter quickly moves toward the lower pressure side and forces an indicator button out the cleaner.

Abstract: SHARED DIRECT MEMORY ACCESS CONTROLLER     ABSTRACT OF THE DISCLOSURE             A microprocessor system includes a microprocessor, a memory, and one or more direct memory access controllers, all connected to a common system bus which includes a system address bus and a system data bus. At least one of the direct memory access controllers is shared by a plurality of subsystem device controllers which may control peripheral devices having diverse characteristics.  The microprocessor is limited in its instruction repertoire and may control peripheral devices only by means of an input and an output instruction.  The shared direct memory access controller includes no circuitry which is specifically for controlling only a single type of peripheral device, the device dependent logic being located in subsystem device controllers.  Data transfers may take place directly between the memory and, through the shared direct memory access controller, any selected one of the peripheral devices.  In order to set up the actual data transfer, the microprocessor executes an Input instruction which addresses the status register in a selected subsystem device controller and returns this status to the microprocessor.  Next, two Output instructions are executed to load a memory starting address into an address pointer counter in the shared direct memory access controller.  Finally, an Output instruction is executed to address a control register in the selected subsystem device controller to load it with a command.  After this last operation the actual data transfer takes place on the byte basis through the shared direct memory access controller between the memory and the selected subsystem device con-troller.  The shared direct memory access controller includes an interrupt priority encoder and circuits responsive to an interrupt that is granted priority for placing the status and address of the interrupting subsystem device controller on the system bus.  Circuits are included in the shared direct memory access controller for "handshaking" between it and the memory, and between it and the subsystem device con-trollers.

Abstract: CONTROL MECHANISM                   ABSTRACT OF THE DISCLOSURE         A vehicle control-mechanism for manipulating three controllable members through one control handle.  The control mechanism includes a support rigidly attached to the vehicle.          The support rotatably carries three control assemblies which are operably connected to one of each of the three controllable members.  The control mechanism also includes a drive assembly rotatably carried by the first and third control assemblies.          The first, second and third control assemblies and the support have force selectively transmitted therebetween by a roller which is contained in the control assembly by roller retainers of the support.  The force which manipulates the controllable members is derived from the operator selectively pivoting the handle about the third control assembly.  To manipulate the various control assemblies the operator will either pivot the handle to engage the handle and the drive assembly or pivot the handle to engage the handle and the second drive assembly.          The controlling force is supplied to the respective control members by the operator's rotation of the handle about its rotational connection to the third control assembly after the handle has been selectively pivoted about its pivot point.          The final features of the control mechanism are a centering spring which urges the handle into a normal position about its pivot point, which normal position cooperates with a regulator that produces selective engagement of the individual controllable members by sequential pivoting and rotation of the handle.

Abstract: ABSTRACT      An electrical load in series with a source of AC power is connected across the anodes of a triac with the secondary of a transformer being connected between the triac gate and one of the triac anodes.  An electronic switch controls current flow in the primary of the transformer such that a negative voltage is supplied at the gate of the triac during conduction by the primary until saturation of the transformer occurs. After saturation, the electronic switch opens the transformer primary initiating a flyback period during which the triac gate potential rings positive and a consistent peak positive current is supplied to the triac gate from the secondary of the transformer. A half-wave rectifier circuit and transistor may be substituted for the triac for DC load control, or a pair of these transistor circuits may be connected in series to provide AC load control.
