  • Patent number: 6688490
    Abstract: A cover assembly for a container of coffee filters, with a tube, centrally located, extending below the cover. A plunger extending above and below the cover, slidably cooperating with the inner wall of the tube, the lower end terminated with an adhesive substance, the upper end terminated with a knob. When the plunger is depressed the adhesive attaches to the uppermost filter of a stack of nested filters and when the plunger is lifted up the filter is extracted from the nest of filters. The filter is then inserted into a coffee maker receptacle and the cover is pushed down to detach the filter from the adhesive tip on the plunger.

  • Patent number: 4936779
    Abstract: An earth planet model as illustrated in the drawings having a base supporting a globe cradle 28. The globe cradle supports a glove 40 at a north pole bearing 48 and at a south pole bearing 50 with the polar axis of the globe being inclined. The model 10 has a polar shaft 66 with a north pole shaft end 68 extending upward through the north pole bearing 48 and a south pole bearing end 70 extending downward through the south pole bearing 50. A light illuminating means is tiltably mounted on the polar shaft 66 for tilting movement and for rotation with the shaft for illuminating the interior of the globe. The model 10 has a manual adjusting means associated with the north pole bearing 48 for manually adjusting the inclination of the illuminating means in response to the setting of a manual knob. A timer drive is detachably coupled to the south pole shaft end 70 for rotating the polar shaft with respect to the globe. The timer is removably mounted on the base.
