Patent number: 4600420Abstract: A filter having a structural framework (45) formed integral with and surrounding an active filtering area, and a process for manufacturing the filter are disclosed. The process includes (a) masking selected areas (40) on a sheet (30) of filter media, which areas will serve as the active filtering areas in the end filter product; (b) applying to the remaining exposed areas of the media a liquid-phase filler material; (c) forcing the material to fully penetrate and completely saturate the exposed media areas; (d) and curing the filler-saturated media areas whereby the filler material solidifies within the fiber structure of the media making that portion of the media sheet impervious to any air flow therethrough. The sealed media area (45) provides a structurally integral framework which is continuous with the active filtering media area (40) of the filter. The filter may then be secured along its integral framework area (45) to a suitable mounting substrate surface.Type: GrantFiled: October 21, 1985Date of Patent: July 15, 1986Assignee: Donaldson Company, Inc.Inventors: Robert M.

Patent number: 4590108Abstract: An insulating system for fluid conduit pipes and the method of insulating is disclosed. An inner layer of resilient flexible insulating material is wrapped about the outer surface of the conduit pipe. An outer layer of flexible cohesive material which is moisture and vapor impervious is wrapped about the inner layer of insulating material. The cohesive material is wrapped so that portions of adjacent edges overlap to self seal by forming a cohesive seal therebetween. Preferably the wrapping of the outer cohesive material is conducted so as to partially compress the inner resilient insulating layer both circumferentially and radically. The resiliency of the insulating material presses against the cohesive seal and thereby maximizes the cohesive seal and cooperates in holding the insulating system about the conduit pipe. The inner insulating layer and outer cohesive moisture and vapor barrier layer can be easily and concurrently applied by a single operator.Type: GrantFiled: July 11, 1984Date of Patent: May 20, 1986Inventor: Reynold B. Nippe

Patent number: 4522874Abstract: An absorbent article structure is provided comprising a permeable, internal layer (10), an intermediate absorbent layer (20) and a liquid-impervious, outer layer (30). Outer layer (30) comprises an inherently-porous paper length (32) impregnated with a selective adhesive forming a liquid-impervious and air-permeable coat (34), which only adheres to itself. A disposable diaper (50) can be manufactured with the structure, being entirely degradable and eliminating the "greenhouse" effect of traditional diapers having an outer plastic layer. The self-sticking properties of the coat (34) eliminate the need for tapes and tabs on the diaper.Type: GrantFiled: May 24, 1984Date of Patent: June 11, 1985Inventor: Philippe J. Pommez
