Abstract: A unit of furniture, useful as a computer workstation such as a desk, cabinet, or armoire, includes a pullout unit that extends from the unit of furniture. The pullout unit includes a tray for supporting a computer keyboard and mouse, and provides a first writing surface adjacent the tray. The tray may be covered by a movable lid that provides a second writing surface over the tray when covering the tray and a third writing surface when moved to a position for supporting copy referenced while using the keyboard. The pullout unit may also include an extension unit mounted adjacent to the tray and extendable to provide additional writing surface. The extension unit may include a drawer that extends toward the tray. The pullout unit may include a lid stop to cooperate with the unit of furniture to maintain the pullout unit in a stable extended position.

Abstract: A crystal growth inhibitor for azo pigments is disclosed. The crystal growth inhibitor comprises: (1) one or more sulfonated or carboxylated amines, and (2) one or more coupling components selected from the group consisting of acetoacetanilides, naphthanilides, pyrazalones and benzamidazoles; the coupling component being bonded to the sulfonated or carboxylated amines. The crystal growth inhibitor can be produced separately and added to the coupling component prior to the coupling reaction, or it can be formed in situ with the pigment. Preferably, an improved pigment according to the invention includes 2% to 5% by weight of the crystal growth inhibitor. Monoazo pigments including the crystal growth inhibitor have been shown to have greatly improved gloss, transparency and tinctorial strength.

Abstract: A device for dispersing gas into molten metal, the device comprising: (1) a pump having: (a) a pump base including a pump chamber and a discharge, (b) a motor, (c) a motor shaft connected to the motor, (d) a rotor shaft connected to the motor shaft by a coupling and (e) a rotor fastened to the end of the rotor shaft opposite the motor shaft, the rotor shaft positioned in the pump chamber. The motor shaft and rotor shaft each have gas-transfer passages and the rotor preferably includes openings to transfer gas from the rotor-shaft passage into the pump chamber. The pump generates a stream of molten metal traveling through the discharge. Gas is introduced into the motor shaft passage and passes into the rotor shaft passage where it is transferred to the rotor and ultimately escapes through the openings in the rotor and into the pump chamber. As the rotor turns it mixes the gas and the molten metal and this mixture travels through the entire length of the pump discharge.

Abstract: Disclosed is a golf ball designed for longer travel relative the compression of the ball. The golf ball includes: (1) a flexible inner core, preferably comprised of crosslinked synthetic rubber, (2) a perforated barrier shell positioned outside of, and surrounding, the inner core to lessen deformation of the ball when the ball is struck by a golf club, (3) a flexible outer core, preferably comprised of crosslinked, synthetic rubber or windings, positioned outside of and surrounding the perforated barrier shell, and (4) an outer cover, preferably comprised of ionomeric resin material, positioned outside of and surrounding the outer core. The perforated barrier shell reduces deformation of the golf ball upon impact by a golf club and is preferably formed as a sphere centered in the golf ball, preferably having a diameter equal to one-half the diameter of the golf ball.

Abstract: A device for pumping molten metal that eliminates rotor bearing members comprises a pump having a pump chamber including a first bearing surface, and a monolithic rotor having a second bearing surface that aligns with the first bearing surface. The second bearing surface is formed of and integral with the material forming the rotor. Preferably a rigid rotor shaft to motor shaft connection is utilized to rigidly center the rotor within the pump chamber and, hence, within the first bearing surface.

Abstract: A probe for use in sensing moisture content of bulk grain or other granular material comprises a cylindrical tube, for example of plastics, having a tapering nose, and having adjacent said nose first and second electrical conductors wound helically around the tube so that the turns of one conductor are spaced from, and alternate with, the turns of the other conductor. The conductors are electrically insulated from one another by the plastics tube but are exposed on the surface of the tube, or project slightly from such surface, for direct electrical contact with the granular material. The conductors extend through respective apertures in the plastics tube and are connected within the tube to respective insulated conductors extending to electronic measuring circuitry within a handle of the probe.

Abstract: A two-part coating system comprises a first part comprising a blend of an aliphatic polyisocyanate with a non-reactive resin or a liquid epoxide resin and a second part comprising an aromatic polyamine, such that the two parts when mixed together and applied to a surface form a rapid-setting impervious coating. The coating system is suitable for application by spraying using equipment in which the two parts of the system are first combined at the point of spraying, at the spray head. In particular the system may be used to apply an impermeable lining to the internal surfaces of pipelines, for example by means of a centrifugal spinning head.

Abstract: A sub-periosteally implantable prosthesis support structure for a fixed or detachable dental prosthesis includes a framework fitted to and generally conforming to the inner and outer contours of the bony ridge structures of a person. The framework is configured to provide a space extending generally normal to the bony ridge structure to an apex to provide space for subsequent bone growth. A plurality of denture support posts are distributed about the framework and depend outwardly from the apex in substantial alignment with the bony ridge structure. During the fabrication of the prosthesis support structure, a bio-compatible fine mesh screen is fixed to and spans, tent-like, the framework to substantially overlay the bone structure and the space provided for subsequent bone growth.

Abstract: A generator according to the disclosure includes a control system for regulating the output of the generator. The generator, such as a permanent magnet generator, includes multiple windings. For high current applications, the windings are connected in parallel. For high voltage applications, each three-phase set of windings is connected in series. The various windings may be selectively and individually activated by the control system to achieve a desired output current or voltage.

Abstract: A rechargeable battery is charged by connecting the terminals of the battery to an electrical power source. In order to avoid overcharging and undue temperature increase in the battery cell, the course of a least one charging parameter, such as the increase rate of voltage, is surveyed during at least part of the process of charging the battery. This charging parameter surveyed is compared with a number of reference parameter courses representing idealistic or desireable processes of charging the battery for different starting states of charge of the battery. Such comparisons may for example be made by means of a microprocessor, which may also select the reference course with a starting state of charge similar to the actual starting state of charge of the battery. Thereafter the process of charging the battery may be controlled so as to approximate the course of said charging parameter to the selected reference course. The charging voltage may be limited to a maximum value (Vmax).
