  • Patent number: 11959683
    Abstract: A modulating refrigeration system includes an evaporation unit and a condensing unit. The evaporation unit generates a first output airflow comprising a lower temperature, a lower relative humidity, or both than a first supply airflow and directs the first output airflow into a building. The condensing unit generates a second output airflow at a higher temperature than a second supply airflow and discharges the second output airflow to an unconditioned space. The evaporation unit comprises a first valve operable to direct a portion of refrigerant to a secondary evaporator and primary evaporator or to direct the entire flow of refrigerant to the primary evaporator and bypassing the secondary evaporator.

  • Publication number: 20170173930
    Abstract: A method for producing a primary laminate including a tabstock by feeding a seal laminate comprising bottom food contact layers including a foil layer and a top polyester layer to a laminating station wherein either the foil layer of the underside of the polyester layer has been printed; simultaneously feeding a tabstock, which is narrower than the seal laminate, to the laminating station such that the bottom of the tabstock and the top polyester layer of the seal laminate come into contact to form a primary substrate, simultaneously feeding a plastic film stock; and continuously extruding a polymeric adhesive between the top face of the primary substrate and bottom surface of the plastic film stock.

  • Patent number: 9586557
    Abstract: A seat belt buckle for engaging a latch inserted into buckle and retained in a latched mode until released by depressing a press release button. In a locked mode, with the vehicle ignition switch ON and the latch inserted into buckle, a complementary lock is activated preventing press the release button from effecting release of latch from buckle.

  • Patent number: 9533805
    Abstract: A method for producing a primary laminate including a tabstock by feeding a seal laminate comprising bottom food contact layers including a foil layer and a top polyester layer to a laminating station wherein either the foil layer of the underside of the polyester layer has been printed; simultaneously feeding a tabstock, which is narrower than the seal laminate, to the laminating station such that the bottom of the tabstock and the top polyester layer of the seal laminate come into contact to form a primary substrate, simultaneously feeding a plastic film stock; and continuously extruding a polymeric adhesive between the top face of the primary substrate and bottom surface of the plastic film stock.

  • Patent number: 8852725
    Abstract: A vessel closing laminate comprising: a seal laminate comprising a bottom subassembly of layers including a foil layer; and a seal substrate attached to the uppermost layer of the bottom subassembly of layers wherein the seal substrate has a bottom foam layer and a top plastic material layer and further includes a free tab lying wholly within the circumference of the seal; a wax layer on top of the plastic material layer of the seal substrate; and an absorbent liner adhered to the plastic material layer of the seal substrate by means of the wax layer.

  • Patent number: 8308003
    Abstract: A seal for a container for comestibles, especially potable liquids, and in particular for use for sealing polyester containers such as bottles, which is suitable for passage through a PET recycling process, comprises a metal foil layer, a foam layer and a plastics film layer as well as a heat sealable layer below the foil. The foam is selected for its density and thickness so is to confer upon the seal a high buoyancy. The adhesion a between the foam and the foil is increased compared to currently available products, in order to prevent de-lamination between the foil and the foam during the recycling process.
