  • Patent number: 8235712
    Abstract: A device intended to assist in the accurate and controlled shrinkage of thermo-shrinkable container-jacketing material. Said device producing at least an elevated temperature in a heated processing zone. Heat energy available in said heated processing zone primarily derived from a first heat source, preferably pressurized steam. Said first heat source steam exhibiting preferred characteristics related to the controlled shrinking of thermo-shrinkable materials. A second heat source, other than steam, acting in cooperative relationship with said first heat source steam, delaying the decay of one or more preferred characteristics of said first heat source steam. Said first heat source steam, urging said heat-shrinkable materials to shrink, substantially conforming to receiving containers in a preferred manner along one or more axis.

  • Patent number: 8156987
    Abstract: A container labeling machine comprises a conveyor, a pressure sensitive label applying apparatus, a star wheel and at least one indexing mechanism, the conveyor supplying containers to the star wheel and taking away the containers upon release from the star wheel. The star wheel is fitted with rollers at the apices of points of the star wheel, the star wheel receiving containers between the rollers of adjacent apices. The label applying apparatus is adapted to apply the label to the container and rotate the container within the star wheel to adhere the label to the container. The indexing mechanism aligns the star wheel to present the container into a perpendicular relation with the label applying apparatus and retains the container in the perpendicular relation until the label is adhered to the container, the indexing mechanism releasing the star wheel allowing the container carrying the label to the conveyor.

  • Patent number: 7878342
    Abstract: A clothesline system comprises at least two separate cables that are independently tensionable through separate cable tensioning devices. The tension devices are attached together to provide for common, parallel movement of the separate cables though the cables are separately passed around separate pulleys at the both ends of the system. The two separate cables add strength to the system. The separate cables are preferably wound in left and right windings to prevent unraveling of the braid of the cable. By providing separate cables, assembly of the system is less complex as the two loops of cable are separate.

  • Patent number: 7309218
    Abstract: A pump suitable for use with contamination-sensitive fluids such as food products or pharmaceutical fluids includes an outer casing containing an internal cavity, the outer casing having an enlarged opening on one end, a second opening on an opposite end, a first inlet port and a first outlet port. The internal cavity has pumping parts disposed substantially within the cavity, the pumping parts comprising end blocks each having a drive and idler shaft support, a drive shaft and an idler shaft, a plurality of pumping wheels, and a center block with an internal cavity defining a pumping chamber. The enlarged opening of the outer casing is sealed by an end cap, an elastomeric seal and a quickly removable industry-standard clamp. The second opening of the outer casing is provided for the drive shaft and is sealed by an elastomeric shaft seal. The pumping wheels are rotationally active with, but not axially retained, on respective support shafts and are substantially free to slide on their respective axes.
