Abstract: DUAL SENSOR FOR MULTI-NOZZLE INK JET          Abstract A dual antenna structure for inductive sensing of charged ink jet drops.  The structure includes two sense rails or wires, each on an opposite side of a series of ink jet drop streams and perpendicular to the streams.  Conductive shields are located on the fore and aft sides of each sense rail to shield the rail from all but a small portion of each drop stream path.  A separate low impedance amplifier is con-nected to each sense rail and both are grounded in common to the shields.  Using the sensor, various measurements may be made on a jet stream whose drops are charged, including jet align-ment, drop arrival time for establishing velocity, charge electrode operation, and charge phasing.

Abstract: Title of the Invention TRANSFORMER SATURATION CONTROL CIRCUIT FOR A            HIGH FREQUENCY SWITCHING       POWER SUPPLY          Abstract of the Disclosure The present circuit prevents the overloading of power switching elements driving the primary winding of a saturable core transformer.  The overloading protected against is a con-sequence of the differential between the volt-seconds supplied to the transformer core from one direction as opposed to the other direction, which differential, in turn, causes the flux level to integrate up the B-H loop resulting initially in un-balanced primary winding currents and ultimately in a premature saturation of the transformer core in one direction.  The pre-sent circuit controls unbalanced transformer core saturation by forcing the core into saturation in alternate opposite di-rections during the periods when the power switching elements are off when core saturation can have no deleterious effect on the circuit operation.  This is accomplished by providing a re-set (bias) current to the transformer core during each off time, which reset current is in a direction that reenforces the trend towards saturation caused by the latest activation of the power switching elements.  The effect is that when the next power switching element is activated it looks at a flux level which is as far away from its associated saturation point as possible.  This in turn permits a maximum excursion of flux dur-ing the power switching elements drive time.

Abstract: HYDRAULIC ROCK DRILL SYSTEM     ABSTRACT OF THE DISCLOSURE    In a hydraulic percussion rock drill the operation of the working fluid distributing valve is controlled to effect a variation in percussive blow energy and blow frequency by varying the piston hammer stroke.  Actuation of the distributing valve is controlled by a remote controlled hydraulically actuated pressure control valve interposed in a fluid passage which conducts hydraulic fluid from the hammer bore to actuate the distributing valve.  Substantially infinite variation of hammer impact blow energy between high and low limits provides for selecting the maximum penetration rate of the drill for any type of rock con-ditions.  The hydraulic rock drill is connected to a source of hydraulic fluid supplied to the drill at substantially constant fluid power by a variable displacement constant power hydraulic pump.

Abstract: MASS PRODUCING MAGNETIC HEAD CORES WITH CANT ANGLES      Abstract A method for batch fabricating magnetic heads with a desired cant angle in the transducing surface of the magnetic core.  The cant angle reduces the "Minor Bit" phenomenon.  The two parts of the core which require the cant angle are mounted on a fixture so that a grind wheel is simultaneously in contact with both parts.  Materials are simultaneously subtracted (i.e., grind away) from both parts to create mirror images at the surfaces which adjoin the grind wheel.  The surfaces are then cleaned and glassed to provide a core bar with intimate fit.  The core bar is diced into individual cores and is lapped to size.  The individual cores are then fitted into a slider assembly to form the magnetic head.

Abstract: ABSTRACT        An automated mass spectrometric system which is cap-able of analyzing and identifying a wide variety of chemical compounds.  A sample of an unknown compound, in liquid, solid or gaseous state, is introduced into the invented system.  It may be a pure sample or a mixture of compounds.  In either case, its mass spectrum is searched for selected peaks and an attempt is made to compare the intensity of each mass peak to previously stored, characteristic spectra of one or more compounds in a predetermined family of compounds.  If one or more of the compounds in the family of compounds is identified as being present in the sample, its quantity is also deter-mined automatically by the invention.  Moreover, a confidence is index is generated as a measure of the likelihood that the compound identified as being present is in fact present.      The present invention comprises a sample inlet device, preferably a flash evaporator and separator, a mass spectro-meter, electronic means for controlling the operation of the mass spectrometer and electronic means for analyzing the mass peaks for identification.  Based upon the results of data analysis, i.e., comparing of spectra, the analysis means provides signals to the control means to alter the data acqui-sition, in closed loop fashion.  System sensitivity and other operating parameters are automatically varied as required to obtain accurate mass peak measurements.

Abstract: Process for Forming a Paper Web Having Improved Bulk and Absorptive Capacity Wendell J. Morton ABSTRACT          An improved low-density papermaking process particularly suited for use in conjunction with twin wire formation style papermaking machines is disclosed.  In a particularly preferred embodiment, a foraminous drying/ imprinting fabric conventionally utilized to thermally predry a moist paper web is extended to the twin wire formation zone, thereby eliminating one of the conventionally utilized Fourdrinier wire sections.  Extension of the drying/imprinti fabric to the formation zone eliminates disturbance of the deflected portions of the paper web which fill the interstices of the drying/imprinting fabric during formation of the web, thus producing unexpected improvements in finished product bulk and absorptive capacity.

Abstract: ABSTRACT OF THE DISCLOSURE           A load-restraining device is disclosed herein for use in lading-carrying vehicles, such as truck trailers, or in other lading-carrying containers.  The device includes a curtain which is suspended from an overhead support that extends laterally across the top of the trailer and is mounted for longitudinal movement therein.  The curtain includes a plurality of laterally-extending pockets, each of which carries a load-restraining belt.          Belt hooks are provided at opposite ends of each belt for cooper-ation with longitudinally-extending belt rails in the sidewalls of the trailer and a belt tensioner or buckle is provided at the center of each belt.  The pockets on the curtain are posi-tioned on the side of the curtain opposite the lading-engaging face, so as to maximize the strength of the curtain while in use under load.  These pockets may be sewn in close proximity to the belts after installation so as to inhibit passage of the belt end hooks from the curtain and thereby reduce pilferage of the belts.  A pair of corner flaps are provided for positioning between the lading and sidewalls so as to restrain lateral move-ment or bunching of the curtain at its vertical centerline.  An adjustable tamper-resistant connector is also provided for sus-pending the curtain from the overhead support and for vertically positioning the curtain relative to the trailer floor.  The load-restraining device may be used in "piggyback" service and such devices include a pair of vertically disposed corner protectors for shielding the lading from the restraining belts as they wrap around the corner edges of the lading adjacent each of the sidewalls of the vehicle.  The load-restraining device may also be used in intercity or over-the-road service.  In such service,  a plurality of identical devices can be used to separ-ate the lading into sections.  Alternatively, a single restraining device can be used and separator sheets can be provided for separ-ating the lading into sections.
