  • Patent number: 4043011
    Abstract: The invention relates to an "in-chamber" gathering and clipping unit in which the gathering members are rotatable around a common hub and the clip drive punch is driven to advance clips individually from a location coaxially within the hub along a direction radially outwardly onto a bag neck gathered by the gathering members. The radius of the gathering members can be kept short and have their arcuate gathering surfaces so designed that the gathering action takes place within a 90.degree. movement of each of the gathering members, so each gathering member retracts below the hub and still leaves the gathering head narrow in width so it can be incorporated in any one of a wide range of existing vacuum chamber packaging machines.

  • Patent number: 4032038
    Abstract: A device useful for dispensing taped bags includes spaced apart rotatably mounted carriers, a surface therebetween to wind up at least one tape, and a clutch assembly for unidirectional rotation of the wind up surface. In various embodiments, the device further includes a variety of features which facilitate removal of wound up tape, such as a spring which is compressible to provide a clearance, a pin to permit rotation of the wind up surface away from a carrier plate, use of spaced apart flexible rods as the surface whereby the free ends of the rods may be compressed to reduce the surface perimeter, and forming the surface of low friction material. The device is especially useful when used as a component of apparatus having a housing for supporting a supply of taped bags.

  • Patent number: 4025376
    Abstract: In coextruded or extrusion coated, laminated, polymeric films which have been stretched by the inflated bubble technique, liquid can be entrapped between the collapsed bubble walls and can migrate to an interior layer of the laminate to treat same when the layer adjacent to the entrapped liquid is liquid permeable. For example, in a polyethylene/nylon/ethylene vinyl acetate/entrapped water/ethylene vinyl acetate/nylon/polyethylene laminated film the entrapped water will diffuse through the ethylene vinyl acetate layers to keep the nylon layers plasticized and impact resistant.

  • Patent number: 4020228
    Abstract: The invention disclosed is directed to a gel composition, including (a) an aliphatic saturated monocarboxylic acid having from about 10 to about 24 carbon atoms; (b) an interpolymer of ethylene and a vinyl ester of a monocarboxylic acid having from 1 to about 4 carbon atoms; (c) a tackifying resin; and (d) an organic solvent. Substrate surfaces to which the gel composition is applied typically exhibit good resistance to blocking and may be effectively heat sealed to other surfaces at relatively low temperatures in minimum time. In aspects of the invention the coated substrates may be polyolefinic or cellulosic sheet materials, including laminates thereof with vinylidene chloride interpolymer layers. Improved heat sealable substrates and processes for heat sealing are also described.

  • Patent number: 4015402
    Abstract: The invention relates to an apparatus and method for loading heavy, block-like articles such as blocks of cheese weighing 40 pounds or more into flexible receptacles such as thermoplastic bags. The apparatus comprises a reciprocally movable loading carriage and means for bringing an article to the carriage and positioning the article thereon. After the article is positioned on the carriage the carriage moves forward towards a wicketed or taped bag whose mouth is held open by a stream of air. Spreader means are provided on the movable carriage to stretch the bag mouth sufficiently wide so that a block of cheese may be inserted deep into the bag without contacting the mouth of the bag thereby preventing the deposit of grease from the cheese around the bag mouth which would interfere with a heat seal closure of the bag.

  • Patent number: 3997385
    Abstract: Sheets of film-like material such as thermoplastic sheets, coated paper, or metallic foil may be clamped together for radiant energy welding by directing jets of gas against the outer surfaces of two opposed sheets to press or clamp the sheets firmly into contact with each other; and, then by irradiating the contact area to heat the material to its welding temperature, the sheets will be fused together.

  • Patent number: 3997383
    Abstract: An amide/olefin polymeric film laminate suitable for packaging, water cooking, and storing food within the package is prepared by coextruding polyamide and polyolefin layers to form a laminate and then cross-linking the laminate by irradiation. Prior art polyolefin/polyamide laminates delaminate readily when subjected to agitation in hot water, but this tendency is significantly reduced by laminates according to the present invention.

  • Patent number: 3989484
    Abstract: Various isotopes of hydrogen are separated by a cyclic sorption process in which a gas stream containing the isotopes is periodically passed through a high pressure column containing a palladium sorbent. A portion of the product from the high pressure column is passed through a second column at lower pressure to act as a purge. Before the sorbent in the high pressure column becomes saturated, the sequence is reversed with the stream flowing through the former low-pressure column now at high pressure, and a portion of the product purging the former high pressure column now at low pressure. The sequence is continued in cyclic manner with the product being enriched in a particular isotope.
