  • Patent number: 4975174
    Abstract: Vertical gel electrophoresis devices comprising a bottom tank having an electrode associated therewith, a top tank insertable into said bottom tank, the top edge of the top tank extending no higher than the top edges of the bottom tank, and a cover assembly including a lid adapted to be placed on top of said bottom tank and a second electrode. As a safety feature, the second electrode is fixedly associated with the cover assembly so that it is removed when the cover assembly is removed. The device also includes an interlock arrangement so that the cover assembly cannot be inserted in place or removed by a simple vertical motion unaccompanied by a horizontal motion.

  • Patent number: 4909918
    Abstract: A disposable comb for a vertical gel cassette of a vertical electrophoresis device is disclosed. The comb is formed from a single thin sheet of a plastic, preferrably biaxial polystyrene, which has at least a slight degree of resilience. A comb is rectangular in shape, and has a plurality of equally spaced parallel ridges or ribs which extend from one side of the sheet to the other (from top to bottom as the comb is inserted into a vertical gel cassette). The comb has a plurality of relatively wide coplanar flat portions alternating with relatively narrow parallel ridges, which resemble the teeth of a comb. The tops of the ridges are slightly convex.

  • Patent number: 4887376
    Abstract: This invention supplies lures whose polymer being applied to fish attractants and release said attractant into water at an essentially a controlled rate usually for a period sufficient for the attractant fish to arrive at the lure. These polymers may be any that are commercially available or known that has the ability to selectively absorb the lure and then release it controlably into water. The preferred polymers are copolymers of acrylic water swellable polyesters, water swellable polyesthers, water swellable poly urethanes, with the degree of water swellability being controlled by the degree of cross-linking.
