  • Patent number: 11752727
    Abstract: A machine and method for making bags is described and includes a web traveling from an input section to a rotary drum, to an output section. The rotary drum includes at least one seal bar, having a first sealing zone, and an adjacent weakening zone. The weakening zone may be a heated perforator, includes a heating wire, or be disposed to create an auxiliary sealed area. The heating wire can have connected thereto, a source of power that is an adjustable voltage or magnitude, and/or pulsed, and/or a feedback loop. The heating wire ay be an NiCr wire and make intermittent contact with the web and be disposed in an insert. The weakening zone may create a line of weakness that is uniform or varies in intensity, is a separating zone, or includes a heat film, a toothed blade, a row of pins, a source of air, or a source of vacuum. The sealing zones ma include temperature zones, cartridge heaters, cooling air, or hated air, or a source of ultrasonic, microwave or radiative energy.

  • Publication number: 20210003255
    Abstract: A method and apparatus fueling vehicle with gaseous fuel includes storage vessels, dispensing sub-stations and a controller. The storage tanks or vessels can be at different pressures. The plurality of dispensing sub-stations each include a dispensing hose and a control valve. Each dispensing sub-station is in controllable fluid communication with the storage vessels so that fluid can flow from the storage vessels through the dispensing sub-station to a vehicle tank. A dispensing hose, and a control valve of the dispensing sub-stations are in the fluid flow paths. The controller receives feedback indicative of a filling parameter from the dispensing sub-stations, and provides control signals to the control valves of the first and second dispensing sub-station to implement one or more desired fill schemes.
