Patent number: 8771794Abstract: A method for treating flooring not designed for sanding and having a multi-layer wax finish reduces the frequency of stripping the wax layers down to the flooring and recoating the flooring in carrying out periodic maintenance on the flooring. A mobile floor treating machine includes at least one rotating brush which is driven at a first circular speed x for cleaning the flooring and is driven at a second circular speed y for removing the two uppermost layers of wax, where y?2x. The top remaining wax layer is then cleaned with the brush operating at the original circular speed x. Two layers of wax are then sequentially applied to the top remaining wax layer in replacing the two removed layers of wax on the floor and restoring the flooring to its original finish. The brush may be operated at 800-1500 RPM for burnishing and polishing.Type: GrantFiled: October 18, 2011Date of Patent: July 8, 2014Assignee: Minuteman International, Inc.Inventors: Jeffrey W.

Patent number: 8647699Abstract: The invention relates to a process for producing biomedical articles, in particular, silicone hydrogel contact lenses having durable hydrophilic chitosan coating. The chitosan coating is covalently attached to the medical device by performing a crosslinking reaction between chitosan and the carboxylic groups on the surface of a medical device directly in a sealed package during autoclave. The coated biomedical articles obtainable by the process of the invention have desirable characteristics regarding adherence to the substrate, durability, hydrophilicity, wettability, biocompatibility and permeability and are thus especially useful in the field of ophthalmic devices.Type: GrantFiled: February 23, 2012Date of Patent: February 11, 2014Assignee: Novartis AGInventors: Achim Müller, Monika Knuth, Ralf Pasternack, Jens Zotzel, Christine Reiff
