Abstract: INK JET PRINTER APPARATUS AND METHOD OF PRINTING             ABSTRACT OF THE DISCLOSURE               An ink jet printer prints dot matrix characters by removing unwanted drops from a sequence of uniformly spaced drops in an ink jet stream and subjecting the remaining print drops to a vertical raster deflection in timed relation with relative horizontal motion of the jet stream and a record medium.  Selected print drops are individually de-flected fractional amounts in either the horizontal or vertical direction prior to the vertical raster deflection to cause the selected print drops to be deposited at positions intermediate the coordinate intercepts of a rectilinear matrix pattern to cause dot matrix characters to be printed with arcuate line segments and various angles corresponding with con-ventional character shapes.

Abstract: METHOD AND APPARATUS FOR ILLUMINATING      AN OBJECT BEARING INDICIA                    Abstract of the Disclosure A light source in an optical character recognition system is automatically controlled to operate at a plurality of light intensities.  A relatively high light intensity is used to illum-inate an object bearing indicia to be read.  A relatively low light intensity is used at all other times.  A plurality of detec-tors sense reflected or ambient light and produce output signals indicative of the intensity of the reflected or ambient light.          First and second signals are generated to indicate whether the detector output is greater than or less than a predetermined threshold.  The number of first and second signals generated in response to the outputs of the detectors are summed separately.          If the number of first signals equals or exceeds a first predeter-mined number, the object is illuminated at a high light intensity.          If the number of first signals is less than the first predeter-mined number, or if the number of the second signals generated equals or exceeds a second predetermined number, the light source is switched to a low light intensity.

Abstract: TITLE            HIGH-INTENSITY IONIZER            ABSTRACT OF THE DISCLOSURE         A high-intensity ionizer including one or more planar discharge electrodes concentrically mounted in a tubular outer electrode.  In one embodiment, the tubular electrode forms a venturi, and the planar discharge electrode in the form of a disc is mounted on an insulated probe in the throat of the ven-turi.  The walls of the venturi are kept free of particulate matter by either a thin layer of water or an airstream along the wall of the venturi.  Particulate matter is prevented from building up on the surface of the probe by an air vent extending around the probe upstream of the discharge electrode.  A high voltage placed between the discharge and outer electrode gener-ates a high-intensity, corona current-producing, electrostatic field within the electrode gap between the discharge electrode and venturi.  The electrostatic field expands radially and cir-cumferentially so that it is radially and circumferentially uniform.  In another embodiment, a plurality of planar elec-trodes are mounted on a support electrode.  The discharge elec-trodes are spaced apart from each other by at least 1.2 times the distance between the discharge and outer electrodes so that the electrostatic fields extending from adjacent discharge elec-trodes do not interfere with each other.  The planar discharge electrodes may have varying diameters so that the intensity of the electrostatic fields through which a gas flowing through the tubular electrode sequentially passes is varied.  Contaminants in gases flowing through the outer electrode thus sequentially flow through a plurality of alternating electrostatic charging fields and electric collecting fields.

Abstract: FILLER PLUG FOR COIL INSERT IN CONCRETE PRODUCT           Abstract of the Disclosure A plug assembly, for temporary use with a concrete product insert having a coil defining an interior threaded surface, holds the  insert in position adjacent a mold wall and prevents the interior of the coil from being filled with concrete.  The plug assembly includes a plug having a hollow cylindrical elastomeric body defining a cavity which is open at one end of the body and a stem in the cavity attached to the body internally and extending out of the cavity a distance sufficient to provide for use of the stem as a handle. The outer surface of the cylindrical, elastomeric body is proportioned and threaded for firm matching engagement with the threaded coil interior surface upon predetermined radial compression and axial expansion of the body from its substantially unstressed condition.  A support means has a first portion for insertion into the cavity in the elastomeric body and a second portion for attachment to a mold wall.  The support means may be removed from the cavity as the mold wall is removed from the concrete product, and the plug may there-after be removed from the coil by applying a pulling force to the stem.  By use of a cavity closure means, such as a disc having a central opening for surrounding the stem, the plug may be used without the support means in a concrete product insert of the type which is positionable with the coil held vertically in the mold.  The disc has a central opening for surrounding the stem and the diameter of the central opening is less than the unstressed diameter of the stem such that the disc will be held firmly by the plug.

Abstract: TITLE:  VALVE ACTUATOR AND PILOT ASSEMBLY THEREFOR           ABSTRACT OF THE INVENTION A valve actuator and a pilot assembly which may be utilized either alone or with the actuator is responsive to control fluid pressure for moving an operative means of a valve between open and closed positions.  The actuator has a housing defining a cylindrical bore therethrough and a shaft is carried in the housing which is engagable with the operative means.  A piston is carried by one of the shaft and the housing and is sealingly slidable along the other of the shaft and the housing and is longitudinally movable within the cylindrical bore.  A plurality of piston chambers are companionly associated with the piston and is responsive to control of source fluid pressure within a pilot assembly to manipulate the piston.     The pilot assembly comprises a cylindrical housing having pilot means within the housing, the pilot means having valve seat means thereon.  normally free traveling spherical members are provided immediate the pilot means and define valve head means selectively sealingly engagable on the pilot means to open and close the pilot means to control fluid flow therethrough.  A pilot spool within the housing and immediate the pilot means and operably associatable with the pilot means and the spherical members permits selective movement of the spherical members to the immediate vicinity of the valve seat means of the pilot means. The spool is manipulatable in at least one of linear and rotary directions.  Fluid flow causes the spherical members to seek and selectively seal onto the valve seat means.  The spool is selec-tively shiftable in response  to variation of fluid pressure to permit the fluid pressure to act within the actuator to manip-ulate the operative means between open and closed positions.  A     stem extension is provided within the actuator housing and is engaged to the spool, together with resisting means, such as compressible springs and the like, within the housing and are carried around the stem for resisting travel of the spool in one direction.  Differential pressure areas are defined across the spool and are responsive to fluid pressure variance to selec-tively overcome travel resistance of the spool by the resistance means and to thereafter shift the spool.     The present actuator is a self-contained unit and is respon-sive to variations in pressure normally transmitted through the valve manipulated by the operative means thereof.  The pilot assembly and actuator have particular utility on fluid flow lines, such as oil and gas transmission lines.  The invention is equally adaptable to pneumatic and hydraulic systems.
