Abstract: An apparatus and method for soft-starting a three-phase motor for connection to a three-phase power source for driving a three-phase motor. Soft-start provides a way to reduce the amount of starting torque and current during starting conditions. First, second, and third conductors are connected between a three-phase power source and a three-phase motor. A power contactor interrupts and provides current along the three conductors. A phase-shifting element for shifting the phase of the power signal normally outputted from the first conductor to match the phase of the power signal normally outputted from the third conductor is connected between the first and third conductors. A switching apparatus having first and second switch elements is connected between the phase-shifting element and the third conductor. When the first switch element is closed, current flows from the first conductor to the motor via the phase-shifting element.

Abstract: A document dispenser comprises a document guide defining a guide portion of an advancing document path and a document identification code reading aperture formed in the document guide wherein a single detector in communication with the dispenser controller is positioned proximate the document identification code reading aperture and is operative to read a specific document identification code through the document identification code reading aperture. Correlated data, indicative of a specific document identification code and corresponding document data input during dispensing of a document carrying the specific document identification code, is generated subsequent the reading of the identification code. A plurality of alternative document identification code reading apertures are formed in the document guide.

Abstract: A grouping system for a packaging line is provided with first and second pin conveyors adapted to group predetermined number of articles in a line without segregating the group from the line has the ability to feed the line of articles in timed relationship to a third pin conveyor which engages the leading group of articles from the line to accelerate it into a flight bar conveyor system provided in a continuous motion packer that is capable of packing the group of articles into a case fed into the load station in timed relationship with the progress of the article group through that load station.

Abstract: A tool for roll crimping a flange cover onto a flange, the tool having a body, a first roller having an axis and being supported on and fixed to a first shaft having a coincident axis, and a second roller having an axis and being supported on and fixed to a second shaft having a coincident axis, the rollers being biased toward one another. The first shaft and second shaft are rotatingly driven and one of the axes is movable relative to the body which allows the first and second rollers to move toward one another.

Abstract: A security device comprises a cable whose ends are engageable within a plunger. The cable is threaded around a door handle or other item to be secured and then, with the cable ends engaged therein, the plunger is slid within a housing for retention by a locking slide. Retraction of the plunger into the housing moves a slide upwardly. This movement causes a pivotally mounted striker to be flipped from one end position to another by an over-center spring arrangement. In moving, the striker strikes a number of wheels each carrying a sequence of numbers. The wheels are rotated and a random number is displayed. If, subsequently, the plunger is released to release the cable, the wheels are struck again by the striker whereby the displayed number is changed. The number is changed again if the plunger is repositioned. The chance of the same number being randomly generated is insignificant. Thus, any opening and closing of the security device is immediately apparent because of the change in the number displayed.

Abstract: A process for regenerating molybdenum containing ammoxidation catalyst comprising replacing the molybdenum loss from the catalyst during the ammoxidation reaction wherein ammonium dimolybdenum is utilized as the source for replacement of the molybdenum loss from the original catalyst.

Abstract: A construction for a laminated window label is provided and includes a transparent film having an adhesive on one surface thereof, liner stock having first and second release-coated surfaces which is adhered on one surface to the transparent film, and an opaque layer which is adhered to the other surface of the liner stock. The transparent film and opaque layer preferably include die cut label portions. Variable and nonvariable information may be printed on the die cut label portion of the transparent film, and the opaque layer may be removed from the construction and replaced onto the surface of the film, thereby laminating the label portion of the opaque layer to the label portion of the transparent film. The two label portions may then be peeled away from the remainder of the construction as a single label which is then applied to a transparent surface such as a window.

Abstract: A fan assembly. The fan assembly comprises: a fan having an axis and an outer periphery; a housing about the fan; and a cutoff separating fan inflow from fan outflow. The cutoff is preferably arranged parallel to the axis and is proximal to the outer periphery. The cutoff includes first and second layers. The first layer provides structural support and has a plurality of apertures therethrough. The second layer is formed of an acoustically insulating material.

Abstract: A process for manufacturing an unsaturated mononitrile selected from the group consisting of acrylonitrile and methacrylonitrile comprising reacting an olefin selected from the group consisting of propylene and isobutylene, ammonia and oxygen in a reactor zone in the presence of a catalyst to produce a reactor effluent containing the corresponding unsaturated mononitrile, transferring the reactor effluent containing the unsaturated mononitrile to a quench column wherein the reactor effluent containing the unsaturated mononitrile is contacted with at least a first aqueous stream to cool the reactor effluent, transferring the cooled reactor effluent containing the unsaturated mononitrile to an absorption column wherein the reactor effluent containing unsaturated mononitrile is contacted with at least a second aqueous stream to separate and remove the unsaturated mononitrile as a bottom stream from the absorption column, transferring the bottom stream containing the unsaturated mononitrile to a recovery and puri

Abstract: The present invention relates to a gutter assembly for use with a longitudinally extending trough or gutter having an opening extending therethrough. The gutter assembly includes an outlet having a flange adjacent its upper end. The outlet extends through the opening with the flange adjacent the trough. A locking ring surrounds the outlet and is positioned adjacent the trough in opposed relationship to the outlet flange.

Abstract: A semi-monolithic ring cavity for a second harmonic generation of laser frequency including a nonlinear crystal, an input mirror, an output mirror, a first point, at which a fundamental wave is incident onto the input mirror, a second point, at which the fundamental wave is incident onto the output mirror along with a second harmonic wave, and a third point, at which the fundamental wave reflects totally from a side surface of the nonlinear crystal. One of the input and output mirrors is coated with a dielectric and separated from the nonlinear crystal whereas the other mirror is formed on the nonlinear crystal. The fundamental wave forms a ring cavity in such a manner that the second harmonic wave is generated only along an axis extending through the first and second points. The semi-monolithic ring cavity exhibits a stable frequency characteristic and a high transform efficiency when a second-harmonic generation of continuous-wave laser frequency is carried out.
