Abstract: SEQUENTIAL INJECTION SYSTEM WITH PULSE OVERLAP    ABSTRACT OF THE DISCLOSURE       A multipoint electronic fuel injection system with overlapping sequential injector actuation is disclosed. A plurality of dual injector driver circuits are provided corresponding to an equivalent number of solenoid fuel injector pairs supplying fuel to an internal combustion engine.   The injectors are partitioned into two groups with each pair assigned one injector from each group.  By sequentially actuating first members of one group and then members of the other, every injector can be actuated for an extended portion of an injection cycle up to one full  engine  revolution.    A  bilevel  select signal initiated with the actuation signal  is gated to each driver circuit to enable each injector of a pair for one half of the sequencing period.   Associated with each driver circuit is an independent pulse generator which is additionally triggered in the sequence.  The duration of the pulse width signals from the generators are dependent on the instantaneous engine operating parameters at the time  of  actuation.    Further  included  is  an  inhibit feature for each pulse generator operable to extend the pulse width for the duration of time between two actua-tions.   The  pulse  width  is  extended  by  the  inhibit feature for cold cranking pulses during starting con-ditions   and   for   acceleration   enrichment   pulses. Provision  is  also made  for  blanking  the pulse width signals to the driver circuits during conditions when the engine may flood.

Abstract: Title of the Invention PRODUCTION OF FUEL     Abstract of the Disclosure The production of fuel comprising an emulsion of coal particles, oil and water or a dispersion of coal and oil in which pyrites, ash and other impurities are removed from the coal particles and the particles reduced in size by forming a slurry of contaminated coal particles and water and exposing that slurry to violent sonic agitation to cause the impurities to be detached from the coal particles and the particles to be reduced in size.  The coal and impurities are thereafter separated and the coal subsequently incorporated into a fuel. The process may also be used to separate other minerals which are bonded mechanically as distinct from chemically, to each other.

Title: Optical reader for bar coded labels

IPC: G06K7/10

Granted: 1983-05-17
Abstract: TITLE OPTICAL READER FOR BAR CODED LABELS        ABSTRACT A circular scan reader utilizes oscillating mirrors (34, 36) and associated optics (22, 24) to generate a circular scan pattern of laser light focused to a small spot.  The angle of the scan emanating from a point just inside the reader through a window (21) forms a conical shape which permits scanning inside a yarn tube (10) without inserting any portion of the reader into the tube.  When the scan passes over a bar coded label (12), the changes in reflection of light between the bars (12a) and spaces (12b) are detected by a photodetector (38) mounted on the face of the window (21).  These fluctuations in light which correspond in width to the bar and space width are converted to an electrical signal that is amplified, and decoded.  A driver circuit (50, 52, 53, 54, 55, 34, 35) for the oscillating mirrors controls the scan rate and scan pattern.  The scan rate is modulated to cause a variation in the sweep depth in the tube thus providing an area scan.  The area scan reduces the need for accurate label placement in the tube core.

Abstract: ABSTRACT     A self-cycling reciprocating piston motor has the piston biased in return stroke direction and driven in power stroke by air pressure introduced between the head of the piston and a closure across the end of the working chamber cylinder.  A valve which closes an exhaust port leading from the working chamber, is opened at the end of the power stroke by working chamber air pressure and the air pressure is evacuated from the working chamber.  The valve is returned to closing relation to the port by the returning piston, thereby resetting the motor for another cycle of operation.  The cylinder is mounted on a ring member which in turn is mounted on a base plate, a guide bearing bushing guides the piston rod through the base plate, and the end of the ring member serves as a power stroke stop for the piston.

Abstract: ABSTRACT OF THE DISCLOSURE         The present invention is for an induction meter having  a voltage  and a  current magnetic sections each producing magnetic flux for rotating an electroconductive disk  at  a  rate  responsive  to the magnetic  flux.  The voltage magnetic section is comprised of a substantially E-shaped  laminated  magnetic  core  having  a  center  leg terminating at a main pole face and two  adjacent  legs terminating at coplanar auxiliary pole faces on opposite sides of the main pole face.  The first and last laminae of  the core define a first and a second side,  respec-tively,  of the core.  A voltage coil is wound about the center leg.  A fixed light load adjuster bracket is lo-cated in magnetic proximity to the first side of the core.          The bracket has a fixed tab extending over a portion of one of the auxiliary pole faces.  A nonmagnetic spacer is located between the first side of the core and the light load adjuster bracket.  The spacer,  the light  load ad-juster bracket and the laminae of the core are fastened together so as  to provide a rigid assembly.  The light load adjuster bracket carries a movable tab extending over adjustable portions of the other auxiliary pole face and the main pole face thereby providing an adjustable mag-netic flux shunt path.  The light load adjuster bracket toether with both the fixed tab and the movable tab act as an additional magnetic flux shunt path.
