  • Publication number: 20230293372
    Abstract: A self-righting portable urinal container includes a housing, a semispherical drip lip, a screw top and loop handles. The housing defines an inner space and has a round open top opposite a base. The base is either rounded or planar (flat base). The round open top has an internally threaded neck at an offset to the housing and the base has a weighted ballast. The semispherical drip lip surrounds at least a portion of portion of the round open top or the threaded neck. The semispherical drip lip forms a urinal receptacle. The screw top has a top handle and a threaded bottom. The threaded bottom includes a seal. The threaded bottom is removably connected to the internally threaded neck of the round open top. The first loop handle is fixed to a first outer portion of a continuous wall of the housing.

  • Patent number: 10113491
    Abstract: An actuation system for a valve is disclosed. The actuation system comprises a housing having an end wall. A first piston and a second piston is slidably positioned within the housing. The second piston is positioned between the first piston and the end wall. A piston rod is coupled to the first piston and slidably extends through the second piston and the end wall. The piston rod is configured to be coupled with the valve. A first spring is arranged between the first piston and the second piston. Further, a second spring is arranged between the second piston and the end wall. The first spring and the second spring are configured to bias the valve to a closed position.

  • Publication number: 20070080047
    Abstract: Commercial production transport systems, mechanisms, and guides for food processing are configured so as to automate food transport. The system can direct food to travel serially over side-by-side predetermined travel lanes using one or more of a pick-up mechanism and/or router guide channels to pick-up and/or laterally translate the food product form the first travel lane to the second travel lane so that it travels greater than one, and typically a plurality, of revolutions about a tier or level in a vertically stacked food processing unit before moving to the next tier. Associated methods redirect and/or laterally translate food being transported in an automated food processing system.

  • Publication number: 20060288879
    Abstract: Commercial production transport systems, mechanisms, and guides for food processing are configured so as to automate food handling and/or transport. The systems employ fingers that can be inserted to gap spaces in a carrier surface so as to dislodge, guide and/or route food to travel over predetermined travel lanes. Associated methods can angularly translate food being transported in an automated food processing system in a longitudinally offset direction.

  • Publication number: 20060128295
    Abstract: Methods, systems, and associated devices for supplying support members to a product loading station, loading, and automatically removing loaded members therefrom include: (a) advancing in spaced-apart relationship, a plurality of carrier members having opposing first and second ends and an associated width and length, along a selected travel path to a loading station; (b) presenting, in serial order, the carrier members to the loading station in a substantially horizontal orientation; (c) discharging elongated product from a winder arm that moves in a selected pattern about the carrier member at the loading station; (d) straddling elongated product over each respective carrier member at the loading station responsive to the discharging step so that portions of the elongated product are serially draped over the carrier member along a length thereof, the straddling being carried out so that certain lengths of the elongated product hang from opposing sides of the carrier member; and (e) advancing the carrier mem

  • Publication number: 20050130572
    Abstract: Methods, systems, and associated devices for supplying support members to a product loading station and automatically removing loaded members therefrom include: (a) advancing in serial order and spaced apart relationship, a plurality of elongated support members having opposing first and second ends and an associated length, along a selected travel path; (b) loading each of the elongated support members individually with a respective continuous length of multiple loops or multiple discrete lengths of elongated product at the loading station; and (c) advancing the loaded elongated support members away from the loading station along the selected travel path.

  • Publication number: 20050124279
    Abstract: Automated loaders are configured with winding mechanisms that wind elongated products directly onto transfer members, such as sticks or rods, by causing the arm to follow a repetitive motion pattern above and below the stick or rod to discharge the elongated product in a winding motion onto the stick or rod. Methods for discharging elongated product, such as encased meats, so that they loop directly onto the stick, bar or other desired food support is also described.
