  • Patent number: 9656882
    Abstract: A water treatment composition includes a water soluble film formed into a sealed pouch. The pouch contains a composite of a phosphate removing substance, a polymer flocculant, or an enzyme, or any combination. The phosphate removing substance, the polymer flocculant, and the enzyme are bound to each other within the composite. The pouch is added to a body of water. The pouch dissolves to release the compounds and treat the water.

  • Patent number: 8042478
    Abstract: An automatic panel cutting and edge seaming system includes a series of side edge cutting and seaming assemblies that receive a fabric material and trim and sew seams along the side edges of the fabric material to form a desired width panel. Puller rolls pull the material through the side edge cutting and seaming assemblies and feed the trimmed and seamed fabric material to a cross-cut sewing assembly. After a sufficient length of fabric material has been fed to form a desired size panel, the cross-cut sewing assembly is engaged to cut and seam the end of the panel.

  • Patent number: 7984681
    Abstract: A system for automatically attaching a flanging material to the edges of a panel such as for a mattress, including a work table on which the panel is supported and a sewing assembly having a sewing machine located along a path of travel of the panel across the work table. The flanging material is fed from a supply of flanging material located adjacent the sewing assembly, and is attached to the side edges and about the corners of the panel by the sewing machine of the sewing assembly. A clamp mechanism engages and holds the panel as the sewing machine of the sewing assembly attaches the flanging material about the corners of the panel.

  • Patent number: 7412936
    Abstract: An apparatus for attaching a gusset to a panel includes a gusset folder that receives and folds a gusset material to form the gusset. The panel is supported by a sewing table. A sewing machine is positioned relative to the sewing table so as to be able to sew the gusset to the panel. A gusset guide guides the gusset toward a selected edge of the panel so that the gusset is held in substantial alignment with the edge of the panel. An edge detector detects when a next edge of the panel is approaching the sewing machine. A turning mechanism is positioned along the sewing table and is moveable into engagement with the panel. The turning mechanism turns the panel relative to the sewing machine when the edge detector detects the next edge of the panel is approaching the sewing machine.

  • Patent number: 7185684
    Abstract: A mobile fill station for filling propane cylinders by weight and volume. There can be up to three cabinets in the system wherein any one of the cabinets can have a beam scale with a hydraulic automatic stop device to stop filling automatically as the total weight of the cylinder reaches a pre-set scale limit. Any one of the cabinets can also include a flow meter to stop filling when an operator monitors an amount on the meter and manually stops propane flow. The cabinets could also include an electronic scale with a digital indicator where filling stops automatically as the total weight of the cylinder reaches a pre-set computer limit.
