  • Patent number: 6561775
    Abstract: The present invention provides an electric submersible pump assembly with a latch device permitting downhole connecting and disconnecting of the pump and motor. The latch device includes a pump latch connector and a motor latch connector that allows a pump and an electric submersible motor to be disposed in a wellbore independently and then connected. The pump latch connector attaches to the pump and includes a rotor connector box and a stator connector pin. The motor latch connector attaches to the motor and includes a rotor connector pin and a stator connector box. The rotor connector pin is disposable in the rotor connector box and the stator connector pin is disposable in the stator connector box thus connecting the previously suspended motor and motor latch connector to a retrievable pump, with the pump latch connector attached.

  • Patent number: 6450125
    Abstract: The present invention is directed to an enclosure for the containment of livestock. Preferably, the livestock enclosure includes a floor assembly forming a planar floor surface and an overlay assembly operably coupled to the floor assembly for selectable engagement with the floor assembly. Preferably, the overlay assembly includes a traction grid having a plurality of grid apertures extending therethrough, wherein the overlay assembly is configured to be placed adjacent the planar floor surface to provide traction for livestock placed within the enclosure. The overlay assembly is preferably configured to be moved, thereby allowing waste from the livestock to flow through the grid apertures and onto the planar floor surface to facilitate removal of said waste from the planar floor surface to clean the enclosure.

  • Patent number: 6406730
    Abstract: The present invention comprises a method and apparatus for treating a low acid food product. The low acid food product is first acidified to produce an acidified food product and then packaged as the acidified food product. The acidifying step comprises addition of a GRAS acid to adjust the pH to below about 4.5. The acidified food product is then deacidified to return the acidified food product to the low acid food product having a pH above 4.6. The deacidification is accomplished through the addition of an alkaline substance in an amount sufficient to deacidify the acidified food product to a pH of from about 5.8 to about 7.5.

  • Patent number: 6383541
    Abstract: The present invention provides a method for the disinfection of seafood. The inventive method includes the steps of (a) preparing a concentrated aqueous solution of a chlorine dioxide liberating compound having a concentration of from about 0.2% to about 25% by weight of the chlorine dioxide liberating compound and having an amount of an acid sufficient to adjust the pH to from about 1.0 to about 5.0; (b) diluting the concentrated aqueous solution to provide a dilute, acidified solution having a concentration of from about 0.00017% to about 0.17% by weight of the chlorine dioxide liberating compound; and (c)contacting the dilute, acidified solution with seafood to disinfect the seafood. Preferably, the chlorine dioxide liberating compound is an alkali metal chlorites, with sodium chlorite and potassium chlorite being particularly preferred. The acid may be any acid generally regarded as safe, as that term is used in the Code of Federal Register, 21 CFR 170.35 and 21 CFR 170.30.

  • Patent number: 6132748
    Abstract: An important and central aspect of the present invention is the use of expanded amorphous aluminum silicate (EAAS) as a vehicle for a chlorite salt. This vehicle, when exposed to moisture, will release chlorine dioxide (ClO.sub.2) for purposes of deodorization or microbial suppression. Thus, where a particular area or volume is to be deodorized or made less microbally contaminated, the EAAS-chlorite salt (most preferably sodium chlorite) is placed in the area or volume to be treated and moisture is permitted to interact with the material. The result of the moisture is to permit the chemical reaction (presumably acidification) of the chlorite salt to yield chlorine dioxide gas. While normal EAAS has some inherent acidity, the inherent acidity is low enough so that, even when a chloride salt is encapsulated in the EAAS and the resultant mixture exposed to moisture, ClO.sub.2 release is very slow and over an extended period. Under most conditions, a more rapid release of ClO.sub.

  • Patent number: 6088185
    Abstract: An apparatus and method for detecting rotational vibration applied to a disc drive having a rotary actuator adjacent a rotatable disc. The actuator supports a head adjacent a recording surface of the disc and an actuator coil in a magnetic field of a magnetic circuit of a voice coil motor. A second, velocity sense coil is further coupled to the actuator and immersed in the magnetic field of the magnetic circuit, with the velocity sense coil being electrically isolated from the actuator coil. Rotational vibration is detected in relation to a sense voltage induced across the velocity sense coil as the magnetic circuit is moved relative to the velocity sense coil. A data transfer operation between the head and a host device is interrupted when the magnitude of the rotational vibration exceeds a specified magnitude.

  • Patent number: 6023027
    Abstract: A guard for cables that extend alongside a coupling in a tubing string includes a base and a clamp member that are hingedly interconnected to fit about the coupling and portions of the cables beside the coupling. Hinge elements, formed on sections of the clamp member at opposite ends of the guard and received by hinge grooves formed in end members of the base, are connected together by a hinge rod and a projection on a rib connecting the base end members extends partially about central portions of the hinge rod to secure the hinge elements within the hinge grooves. Bolt grooves are formed in free ends of the base end members opposite hinge ends of the base members in which the hinge grooves are formed to receive the ends of a base portion of a u-bolt that is secured to the base by a projection formed on a rib connecting the base end members and extending partially about the base portion of the u-bolt.
