  • Plastic bag sealing apparatus with an ultracapacitor discharging power circuit
    Patent number: 6058998
    Abstract: An energy discharge circuit includes a high-power ultracapacitor 4 for providing pulses of electrical energy to a sealer 8 in an apparatus for sealing a plastic bag 38. The ultracapacitor 4 is charged by a power supply 30 and discharges the stored energy to the sealer 8, thereby enabling the sealing apparatus to seal the plastic bag 38 without the need for a high energy continuous electrical power source.

  • Exhaust flow rate vacuum sensor
    Patent number: 5655357
    Abstract: A vacuum sensor for use in devices for the vacuum packaging of perishable items. The vacuum sensor senses fluid pulses or flow expelled from an exhaust port of a pump of the vacuum packaging device. The sensor converts a force of the fluid pulses or flow into a signal that changes with a change in the force of the fluid pulses or flow. The signal is then communicated to a control circuit which uses the signal to display the progress of the vacuum process and/or shut down the pump upon establishing a substantial vacuum within the package.
