Abstract: CIRCUITRY FOR PERFECTING INK DROP PRINTING AT NONLINEAR    CARRIER VELOCITY          Abstract of the Disclosure Electronic lead determining circuitry operates to advantage with nonlinear relative movement between a paper record medium and an ink drop projector carrier of ink drop printing apparatus.  Electronic lead determining circuitry is arranged for calculating the proper lead times for displacing the normal print enabling signals by factors dependent on the actual carrier positions and the lead for projecting ink drops at the desired positions.    Ink drop printing apparatus of the type having a carrier bearing an ink drop projector across a record medium at a velocity relative to the record medium which may be varying substantially --either by design or unintentionally--, and bearing print position location detecting elements, and bearing ink drop projection controlling elements is perfected by controlling electronic circuitry for calculating lead time at a given print position for enabling printing at a predetermined designated print position precisely at the predetermined desired location on the paper.  Preferably, a velocity-time profile for the apparatus is chosen for low g-force loading of the moving components, and printing is effective over most of the profile in contradistinction to conventional printing over linear portions only of conventional profiles.  Phase locked oscillator loop circuitry is used for tracking the carrier position and adjusting phase, while several alternate lead calculating circuitry are arranged in cooperation therewith.  Print position and carrier travel direction data are updated in real time as the apparatus operates under data processing control.

Abstract: METHOD AND APPARATUS FOR COMMINUTING        PULVERIZABLE MATERIAL                 Abstract of the Disclosure An impact pulverizer mounts a rotor concentrically within an octagonal shaped reduction chamber.  The rotor has a substantially solid core and generally radially extending impact blades, each of which slopes in the axial direction of the rotor.          Upon rotation of the rotor, the blades strike pulverizable material and propel the same radially of the chamber and against the interior walls thereof.  The slope of the blades moves the pieces longitudinally of the chamber from the intake toward the egress end  in a generally spiral rotational motion as the pieces ricochet off the interior walls and back against the rotor blades, striking each other as they so progress.  The striking and rico-cheting cause the pieces to break up and be reduced in size as they travel towards an outfeed opening.

Title: Coded record and methods of and apparatus for encoding and decoding records

Abstract: A CODED RECORD AND METHODS OF AND APPARATUS      FOR ENCODING AND DECODING RECORDS                 Abstract of the Disclosure A novel record with alternate width modulated bars and spaces is decoded by comparing the width of each bar or space with a pair of reference values based on the product and quotient of a constant and the width of another bar or space to establish bit value.  When the width value is greater or less than the reference value, the bit value is established.           When the width values lie between the reference values, a state of equality is established which is resolved into a bit value by reference to the results of a prior or subsequent comparison.  A system embodying the method includes storage means for storing width values, reference registers for establishing successive different sets of product and quotient reference values, and comparators controlled by the stored width and reference values for establishing the greater and less than and equality status conditions.  In one embodiment, a shift register and logic circuits controlled by the status conditions provide dynamic interpretation of the status conditions into code bits as the character is read.           In another embodiment, the status conditions are stored and then translated into code bits after a complete character has been read.  In one code set, each character code of seven bits formed by four bars and three spaces uses five bits to define the character and the remaining two bits to provide separate bar  and space parity bits.  This and the fact that only one space "1" and one bar "1" are included in a proper code results in a code with an extremely low expected rate of undetected error.  The system also includes separate parity check circuits for the decoded bar and space bits.

Abstract: MODE CONTROL OF HETEROJUNCTION  INJECTION LASERS AND METHOD     OF FABRICATION                    ABSTRACT OF THE DISCLOSURE           Mode control both for longitudinal and fundamental transverse modes can be achieved by employing a mesa structure on the laser substrate during fabrication.  The mesa will provide significant variations in the thickness of one or more hetrostructure waveguiding layers that may be fabricated on the mesa formed substrate.  As a result, the equivalent index of refraction for each waveguiding layer will be different.          For longitudinal mode operation, a branching directional coupler can be directly fabricated during preferential LPE growth due to the presence of the mesa formed on the sub-strate.  For fundamental transverse mode operation, oscil-lation can be restricted to a high gain region in a wave-guiding layer due to the presence of the mesa and thickness variation and curvature in the active layer.  Connected or juxtaposed stripe contact geometry can also be employed to provide a multicavity effect in a light waveguiding layer to enhance longitudinal mode selectivity.
