Abstract: ENCODING SCHEME FOR FAILURE DETECTION IN RANDOM ACCESS MEMORIES     ABSTRACT             A virtual encoding scheme for use in random access memories is disclosed.  Data errors, incorrect memory word access errors, and errors resulting from multiple memory word access are all detectable through use of the encoding scheme.  The novel approach includes the generation of two distinct check code fields which are stored along with the data.  A first check code field is generated as a function of the data and is cap-able of reflecting all unidirectional data failures.  A second check code field is generated as a function of the address of the memory word containing the data and is capable of reflecting incorrect memory word access.  The two check fields can be stored either in the same physical memory location as the data or in a supplementary memory at an address numerically identical to that at which the data is kept.  During readout, the two check fields are regenerated and compared to those previously stored.

Abstract: ABSTRACT OF THE DISCLOSURE      A  dual metering valve for a diesel engine pilot fuel in-jection system.  The dual valve includes a pilot fuel metering valve, a main fuel metering valve, and a logic system.  The pilot and main valves are of the spool type and each includes a sole-noid for axially moving the spool from an unactuated position to an actuated position and a spring which returns the spool to an unactuated position when the solenoid is de-energized.  The logic system controls the supply of unmetered fuel to a chamber in each spool and utilizes the position of the spools to provide the logic control.  When the main spool is in its unactuated position it ports unmetered fuel to the pilot spool chamber; when the main spool is in its actuated position it blocks the supply of un-metered fuel to the pilot spool chamber.  Pilot spool control is the reverse of the main spool control; i. e., when the pilot spool is in its unactuated position it blocks the supply of un-metered fuel to the chamber in the main spool; when the pilot spool is in its actuated position its ports unmetered fuel to the main spool chamber.  The logic allows fuel metering when the spools move from their unactuated positions to their actuated positions.  The logic prevents fuel metering when the spools move from their actuated positions to their unactuated positions.  The pilot and main spools are each provided with a diagonal shoulder and means to vary the angular position of the spools and dia-gonal shoulders to control amounts of fuel metered by the valves.

Abstract: ITERATIVE COORDINATE DATA APPROXIMATION SYSTEM FOR PHOTOEMISSIVE          PIXEL PATTERN DISPLAYS          Abstract of the Disclosure Almost any Photoemissive Pixel Pattern Display Tube (PPDT) System, such as one for a PMDT matrix display system is capable of supplying an indication of coordinate data for input to data processing systems and the like with this electronic photoresponsive data approximation system.  A photoresponsive probe with relatively large optical aperture stop is coupled to suitable electric current amplifying circuitry which in turn is coupled to data resolving cir-cuitry for gating counting circuitry coupled to the display matrixing circuitry for determining the coordinates of the location of the probe in terms of the geometrical dimensions of the display.  The probe is arranged for sensing a pre-determined differential in photoemission as the cathode ray beam passes through the aperture stop.  Conveniently, the aperture stop is circular and from the top the successive intercepted raster scans are longer up to the center of the stop.  The electronic circuitry responsive to the probe is arranged for timing the beginning of each scan as inter-cepted.  Upon timing the maximum duration of interception at the center of the aperture stop, one coordinate, y, is determined.  The other coordinate, x, is then determined by averaging the time of beginning and the time of ending this central intercepted scan.  Alternately, this x coordinate is determined by locating the central point of this central intercepted scan.  The technique is applicable to polar coordinate (?,.theta.) data systems and to spiral and serpentine scan systems with only slightly more complex circuitry required.  Variations in photoemissivity as the information is displayed are less effective in the determination than in the conventional systems and the approximation system is compatible with almost all photoemissive matrix display systems.
