  • Patent number: 6672001
    Abstract: A method is provided for mulching an agricultural soil bed using a biodegradable protein mulch material. The method includes the preparation of a film forming solution of a film forming protein material. The film forming protein solution is then sprayed directly onto a surface of an agricultural soil bed. The solution dries to form a thin film of protein material on the surface of the agricultural soil bed. The protein material may comprise a plant protein, a milk protein, an animal protein, a whey protein, casein, an egg protein or gelatin. Following a harvest, the mulch material, which is biodegradable, may simply be plowed under.

  • Patent number: 6273960
    Abstract: Methods for cleaning soiled contact lenses are disclosed. The methods involve contacting the soiled lens with a cleaning composition comprising carbon dioxide and carbonic acid as cleansing agents. The cleaning compositions do not require abrasive agents such as polymeric beads, nor ocularly irritating agents such as enzymes or surfactants in order to effectively clean proteinaceous and nonproteinaceous deposits from the surface of contact lenses.

  • Patent number: 5679336
    Abstract: Aqueous pharmaceutical compositions containing a synergistic combination of a quinolone and a polystyrene sulfonic acid polymer are described, wherein the compositions are clear solutions which are comfortable and have sustained release. Methods for use of the compositions are also disclosed. This type of formulation is particularly useful with ciprofloxacin-type quinolones by greatly increasing the solubility of these quinolones, making it feasible to have aqueous solutions containing such quinolones at or near physiological pH.
