Abstract: ABSTRACT          From a human factors standpoint, it is desirable to condi-tion the typewriter to respond to the speed at which a keyboard operator operates the keys to avoid unduly delaying the operator but, at the same time, obviating erroneous multiple printing of characters for slow typists.  The electronics which control the keyboard and processor of a word processing system may time the period for which a standard key or a datum key is depressed during normal cycles.  If, for example, the space bar is depressed for longer than a predetermined time period such as 100 milli-seconds but less than 300 milliseconds, then the delay time before the control logic indicates a repetitive printing will then be extended.  If, for example, the minimum delay time initially set with the power on of the word processing system is 300 milliseconds, then the holding of the space bar for a period of time between 100 and 300 milliseconds will result in the system operating to extend the minimum delay time to 400 milliseconds to accommodate a slow typist.          This sequence may be continued until such time as a space bar depression time greater than 200 milliseconds but less than 400 milliseconds are detected.  If such a time period is detected, then the 400 millisecond typamatic delay time will then be increased to 500 milliseconds to accommodate the very slow typist.  This cycle may be repeated as desired to increase the 500 millisecond delay time to 600 milliseconds.     The time period will then remain at 600 milliseconds until the typewriter or word processing system is turned off and then restarted at a later time. At the later time, the 300 millisecond standard delay time will then be reinitiated.

Abstract: TITLE:  METHOD AND APPARATUS FOR MAGNETIC FLUX TESTING     ABSTRACT OF THE DISCLOSURE    A method and apparatus are provided for effecting the inspection of a ferromagnetic element, or piping, and parti-cularly piping that is already installed. The invention incorporates a device for indicating wall thickness of a length of the ferromagnetic element, including means for producing a value of magnetic flux extending longitudinally through a portion of the element.  A voltage generating device is disposed in surrounding relationship to the element and is movable axially relative to the length of the element containing the value of the magnetic flux.  Means for indicating the voltage generated in the voltage generating means by the value of the magnetic flux also are provided.  Preferably, an axially split spool is provided which may be closed in surrounding relationship to an installed pipe.  A saturation level of magnetic flux is induced in the pipe by a flexible cable which is wrapped around the spool in a multi-turn configuration and supplied with electrical current sufficient to produce saturation.  The spool incorporates in its periphery three axially split pickup coils, the ends of which are brought into interengagement by the closing of the spool around the length of pipe to provide three separate multi-turn current paths around the enclosed pipe.  As the spool is moved along the pipe, the voltage induced in the central pickup coil is amplified, integrated and applied to one Y-axis of a voltage recording device.  The differential of the voltages generated by the two end pickup coils is amplified, integrated and applied to a second Y-axis of the recorder.          The position of the coils along the pipe is indicated by a transducer which generates a voltage signal applied to the X-axis of the recorder.  The recorder thus provides concurrent indication of both the average thickness of the pipe and any discontinuities from the average thickness as indicated by the amplified, integrated differential voltage signal.

Abstract: ABSTRACT OF THE DISCLOSURE           A process and apparatus for measuring, without destroying the specimen, the distribution in the thickness direction of the filler and/or coating materials of paper or cardboard.  by radiation (Ie) emitted by an X-ray tube is excited in the material component of the object of measure-ment to be examined, its characteristic X-ray radiation, the intensity of this radiation being observed.  Measurements are made on both sides of the specimen under examination and the contents of other filler components are determined by X-ray absorption measurements.  The base weight of the paper under measurement is determined for instance by beta radia-tion absorption measurements.  The distribution measurements of fillers are carried out both by measurements of the char-acteristic radiation of the material components excited in the specimen by constant energy X-ray radiation obtained from an X-ray tube and with the aid of absorption measure-ments of radiation obtained directly from the X-ray tube and of radiation produced with its aid in appropriate transfor-mation targets, for eliminating by calculation the disturb-ing effects exerted by the variation in relation to each other of the contents of the filler components.  Alterna-tively, the distribution measurements are carried out both with measurements of the characteristic radiation of the material component excited in the specimen with radiation, obtained from the X-ray tube, varying as to its energy during the measuring cycle and with absorption measurement of the same radiation, to be used in elimination by calcula-tion of the disturbing effect from the variations in rela-tion to each other of the filler components' contents.

Abstract: ABSTRACT OF THE DISCLOSURE The invention comprises a high vacuum compatible electron beam stage having an X/Y and theta coordinate positioning drive mechanism mounted from below the stage.  The stage comprises four plates: a base plate, an X plate slidably mounted thereon and constrained to slide in an X direction, a Y plate slidably mounted on the X plate and constrained to slide in a Y direction, and a theta plate mounted on the Y plate and constrained to translate in the Z direction.  Two rotary capstans, mounted on drive shafts, are coupled one each to the X and Y plates by a metallic band looped around the capstan and attached at opposite ends to the plate.          Rotation of the capstan causes the respective plates to slide in their constrained direction.  The theta plate drive shaft is limited to vertical motion.  The Y and theta drive shafts couple to universal joints.  All three drive shafts couple to bellows joints.  This permits the drive shafts to deflect at small angles.  Each of the drive shafts couples through a rotary vacuum seal to drive motors mounted on a fixed platform exterior to the electron beam vacuum chamber.

Abstract: Abstract of the Disclosure Apparatus and Method for Controlling Internal Size of An Extruded Hose An apparatus and method is provided for continuously extruding an elastomeric hose having a controlled internal size.  A controlled internal size is necessary in order to mount various types of couplings to the hose.  Other hose making processes require extruding the hose on a mandrel in order to control the internal size.  The use of mandrels restrict hose length and require additional floor space due to the lengthy mandrels.  An extruded hose having a controlled internal size is continuously made by extruding an elastomeric material over a first end portion of an internal shaping member and continuously monitoring the flow of air between a gauge member and the internal size of the hose.  The rate of extrusion is controlled in response to the flow of air between the gauge member and the internal size of the hose changing from a predetermined range.  The continuous monitoring of the internal size adjacent the internal shaping member and adjusting the rate of extrusion in response thereto produces a continuous hose with a controlled internal size without the use of long mandrels.

Abstract: Abstract:      A self-cleaning system and method for dispersing aggregates in a fluid medium is provided.  The system is comprised of first and second members operatively associated to form an internal chamber and having an inlet to the chamber for admitting the fluid to be treated.  At least one of the members is biased to-ward the other whereby the introduction of a fluid medium to be treated into the chamber under an oper-ating pressure in the range of from 50 to 1,000 psid (3.52 to 70.3 kg/cm2) provides an elongated orifice between the first and second members having a trans-verse dimension or width of from 1 to 1,500 micro-meters for egress of the fluid medium.  As the fluid passes through the elongated orifice, aggregates contained therein are dispersed. The system is self-cleaning by virtue of the biased nature of at least one of the members toward the other, thereby pro-viding longer onstream operation and requiring less servicing.  The system can be used for treating ag-gregate-containing fluids such as oil well completion fluids, dispersions used in the manufacture of mag-netic tape, and dispersion of particulates such as carbon black and other pigments.
