  • Patent number: 6434789
    Abstract: A moveable sliding glass door track clip guide, ideally formed of plastic, and attached to the bead on the top of the rail on the sill which is subsequently secured in place by a sliding glass door track clip cover which will inhibit the door from jumping the track in strong wind loads. The guide contributes significantly to the general security of the SGD installation, since SGD's, by design, must be lifted then set upon their track. The guide slidably engages the upper bead on the track on the sill and thus resists the effort of the door to jump off the track by actually gripping the track itself. The method of the present invention involves the steps of first positioning a moveable panel in place. Thereafter, the main attachment screw is removed, and passed through the clip assembly. Only after the track clip guide has been positioned over the bead on the rail.

  • Patent number: 3973602
    Abstract: A funnel apparatus for use in filling a container without overflowing and which sealingly engages the filling opening of an imperforate container when the container is being filled with liquid and such apparatus has a vent which terminates below the normal liquid level in the upper portion of the apparatus when in use and through which air displaced from the container being filled must pass. The displaced air from the container creates a signal in the form of bubbles which pass through the liquid within the apparatus until the liquid level in the container closes the vent at which time the bubbles stop and the user is apprised of the fact that the container is substantially full and that pouring into the apparatus should stop. Thereafter the liquid remaining in the funnel apparatus can drain into the container without overflowing.
