Abstract: A industrial fabric of monofilament of polyphthalamide having recurring units including copolymerized hexamethylene diamine and mixtures of copolymerized terephthalic acid, isophthalic acid, and adipic acid. The monofilament has excellent hydrolysis, chemical, and abrasion resistance. It is particularly useful for the cloth in the forming and pressing sections of a papermaking machine.
Abstract: A micro-keratome device for performing eye surgery is disclosed. The device is comprised of a vacuum ring, an applanation shoe and a cutting blade. The cutting blade and applanation shoe are mounted on the vacuum ring with the cutting blade being pivotally mounted to the applanation shoe so that movement of the cutting blade, while the vacuum ring is still mounted to a patient's eye, permits the user to have an unobstructed path to that portion of the eye exposed by the cutting blade. In a further embodiment, the device includes a guard, mounted at one end of the applanation shoe, which collects, protects and positions the previously cut portion of eye tissue.
