Abstract: ABSTRACT An improved automated engine diagnosing device employing a digital data processor and a cathode ray tube monitor for displaying individual engine cylinder numbers in separate association with correlated values of exhaust gas emissions pollutants, Engine timing data associated with the time of firing of individual cylinders of the engine being tested synchronizes select cylinder firing inhibition for orderly accumulating gas emissions data generated from an exhaust probe placed in the tail pipe of the automobile under test. An auto-matic sequential firing inhibition and a manually selectable firing inhibition permits dual modes of data acquisition for developing pollutant data to be utilized by the processor for generating the analysis display on the cathode ray tube monitor.

Abstract: A process for finishing fishing nets Abstract Crimping  of  fishing nets, particularly of the codends of fishing nets  of synthetic filamentary yarn, to be subjected to severe mechanical stressing, can be considerably avoided by impregnating the nets with finish consisting of a mixture of a vinyl pyridine copoly-mer latex, a formaldehyde resin precondensate, formalde-hyde, water and, optionally, a dye, drying the nets thus impregnated and subsequently subjecting the nets to a heat treatment at 130°C to 180°C.

Abstract: SPECIFICATION         SPRAYING APPARATUS AND ADAPTOR WITH EXPENDABLE VALVE ASSEMBLY             ABSTRACT OF THE DISCLOSURE        A valve assembly which mixes two components for delivery to a spraying apparatus.  The assembly is comprised of a core valve mounted in a housing or body which is secured in a chamber in a manner which provides passageways between the housing and the chamber.  A fluid is delivered to the core valve by a first conduit attached to the housing, while air is delivered to the chamber by a second conduit coaxial with the first attached to the chamber.  The core valve is operated by a plunger or push rod which opens the valve permitting the fluid to enter the chamber and causing it to be mixed internally with the air for delivery to a spraying nozzle device.  The valve assembly is operated simultaneously with the valves of the spraying device and may be incorporated into the spraying nozzle device or provided as an attachment thereto.  The valve is also incorporated into a spraying apparatus with an internal fluid mixing chamber which simultaneously mixes two fluids, then delivers mixture to a nozzle for blending with another fluid component.  The spraying apparatus is comprised of a gun body with an integral fluid mixing chamber, a nozzle body attached to the gun body, and a nozzle configured to blend two fluid components coming from the nozzle into a uniform spray.  The nozzle body is connected to the gun body by a hollow tubular nut, having a threaded nipple as a conduit for delivery of a fluid.  The nozzle body has a passageway in communication with the hollow nut for delivering the fluid to a chamber and valve connected to a central aperture of a nozzle removably attached to the nozzle body.

Abstract: TRIM PRESS WITH OSCILLATING    CANOPY SHEET FEED      ABSTRACT OF THE INVENTION           An oscillating canopy is employed in the feeding of an elongate sheet of synthetic plastic material having articles, such as cups, for example, formed in the sheet, to a die which trims the articles from the sheet.  The canopy has a downwardly concave curved upper portion upon which the sheet is supported by a series of rollers.  The canopy is driven in forward and return strokes in pivotal movement about an axis located at a radial distance from the curved upper portion which is a greater distance from the discharge end of the curved upper portion than from the sheet receiving end so that tension is maintained on the sheet during the feeding stroke.  The sheet-supporting rollers are mounted for rotation in one direction only, this direction being that in which the rollers can roll relative to the sheet on the return stroke of the canopy.

Abstract: ABSTRACT OF THE DISCLOSURE:           The step-by-step motor is provided with a stator having an energizing coil for producing a magnetomotive force, and a rotor surrounded by the stator and having an axis about which it is rotatable.  This rotor comprises along its circumferential periphery a succession of alternate magnetic dipoles to which is applied the magnetomotive force from the coil.  The axis of the rotor passes through a bearing positionally fixed with respect to the stator.  The stator of the step-by-step motor includes an inner cylindrical wall adapted for dividing the magnetomotive force of the coil applied to the rotor dipoles and comprising two end rings having polar teeth equal in number to the magnetic dipoles of the rotor, and at least an intermediate ring disposed between the two end rings and made of ferromagnetic material.  This intermediate ring is secured to an inner wall of the coil and comprises two annular rows of polar teeth, the teeth of each row being angularly offset between the teeth in the other row.  The number of teeth in each of these rows is equal to the number of the teeth of the end rings and to the number of the magnetic dipoles of the rotor.

Abstract: CONTROL SYSTEM FOR MANIPULATOR APPARATUS         ABSTRACT OF THE DISCLOSURE         A control system is provided for a programmable manipulator having an arm movable in a plurality of axes that results in improved dynamic performance and control of a mani-pulator arm over a wide range of arm loads, dynamic operating parameters of the arm, and over the full range of arm operating positions.  The control system for one or more of the controlled axes includes several servo control loops utilizing force or pressure feedback from the axis actuators and variable inertia scaling of selected loop command signals and loop parameters.          The variable inertia scaling in accordance with the inertia of the arm provides improved dynamic performance of the mani-pulator arm while maintaining stable servo-loop operation over a wide range of operating parameters.  In a preferred arrangement, the variable inertia scaling is accomplished by the use of a look up table with appropriate interpolation of the table entries.  The look up table is stored in a digital axis processor with the appropriate variable inertia scaling factors being determined by the axis processor for use by the respective axis servo-loop.  The look up table in accordance with various predetermined operating requirements of the mani-pulator apparatus includes data entries representing inertia scaling factors according to the mass of the arm load, the commanded velocity in a particular axis, and the operating positions of one or more of the major control axes of the arm.

Abstract: ABSTRACT OF THE DISCLOSURE         Olefins are polymerized in the presence of a catalyst prepared by reacting trivalent or tetravalent titanium compounds such as a titanium trichloride or a titanium tetraalkoxide, zirconium compounds such as tri-n-butoxy zirconium chloride, an organomagnesium component such as di-n-hexyl magnesium, a halogen source such as ethyl aluminum dichloride and an organo-aluminum compound if the halide source or magnesium component does not contain sufficient quantities of aluminum.  Polymerization processes employing these catalyst compositions do not require conventional catalyst removal steps in order to provide polymers having suitable color and other physical characteristics and these catalysts produce polymers having broader molecular weight distributions and, at higher zirconium amounts, lower melt indices than do corresponding catalysts without the zirconium compound.

The system makes possible the remote determination and constant monitoring of transducer sensitivity, at the controller.  The sensitivity can be adjusted remotely at the controller, and different transducers can have different thresholds simultaneously. These thresholds (limits) can be changed collectively or individually to different settings manually or automatically at the controller.  The system trans-mits reference data for supervision of system ac-curacy.  Compensation for long-term changes is provided for both transponders and transducers in this system.
