  • Publication number: 20180279668
    Abstract: An automatic cigarette-making machine includes a material bin for receiving and selectively dispensing a loose combustible substance suitable to be received and packed within a hollow tube to form a cigarette. A tube bin receives and selectively dispenses hollow tubes. A tube transporting carriage selectively receives a tube from the tube bin and selectively transports a tube between positions at the tube bin and filling station. Filling apparatus selectively moves the combustible substance from the material bin into a tube at the filling station. A pressure sensor is movably positionable proximate to a tube being filled at the filling station to measure or monitor pressure of the combustible substance within the tube while it is being filled. A user interface allows a user to select a desired packing density or pressure within the tube while it is being filled and/or the number of cigarettes to be automatically produced.

  • Patent number: 7570003
    Abstract: A lid assembly for use with a garbage can having a frame that includes a lip at the bottom of lid and a housing. The housing is defined by a lower wall and a sidewall with an opening. A static electricity sensor is positioned in the housing. The lid assembly also includes a displaceable door that moves with the lip to open the garbage can. So that when the static electricity sensor detects the static electricity of a user, the displaceable door slides to open the garbage can and when the static electricity sensor does not detects the static electricity of a user, the displaceable door slides to close the garbage can.
