Publication number: 20160186321Abstract: An apparatus and method for plasma finishing of fibrous materials including paper and knitted, woven and non-woven fibrous substrates such that desired characteristics are imparted are described. The method includes depositing a monomer comprising at least one fluorocarbon monomer with chemical additives, as required, at atmospheric pressure onto the paper or knitted, woven or non-woven substrate; exposing the monomer on a single surface of the fibrous material to an inert gas, atmospheric-pressure plasma, thereby causing polymerization of the monomer species; and repeating this sequence using multiple sequential deposition and plasma discharge steps to create a layered surface having durability against abrasion for both water-based laundry methods and dry-cleaning methods, and normal wear, without affecting the feel, drape, appearance or breathability of the substrate material.Type: ApplicationFiled: October 13, 2015Publication date: June 30, 2016Inventors: Gary S.

Patent number: 6994433Abstract: An eyewear has a gasket between the user and lenses that electrostatically filter the air flow of particulate while still permitting a gentle flow of air to maintain comfort to the wearer of the eyewear, and prevent fogging on the lenses. The electret filter material forms a perimeter around the eyes and lenses to remove, small to large particulates, from microns to millimeters. The filters can be formed with a choice of face contact gasket, baffles, coarse filters, and electret filter density. Baffles or coarse filters over the electret filters are used to protect the electret filter from damage from larger particles and transfer heat to the airflow.Type: GrantFiled: October 7, 2003Date of Patent: February 7, 2006Assignee: Energy Related Devices, Inc.Inventors: Robert G. Hockaday, Patrick S. Turner, Marc D. DeJohn, Carlos J. Navas, Heathcliff L. Vaz

Patent number: 6953637Abstract: A selective gas permeable membrane allows hydrogen to vent from a battery while preventing other gases from entering the battery. The surface of the filter membrane also catalytically combusts hydrogen and oxygen if both are evolved inside the battery and retains the resulting water for use in the battery. The membrane is made with a porous plastic substrate coated with a thin metal film permeable to hydrogen, and additional coatings. These coatings protect the surfaces, and catalytically combust hydrogen and oxygen.Type: GrantFiled: June 1, 2001Date of Patent: October 11, 2005Assignee: Energy Related Devices, Inc.Inventors: Robert G. Hockaday, Patrick S. Turner, Zachary R. Bradford, Marc D. DeJohn, Carlos J. Navas, F. Wade Uhrich, Heathcliff L. Vaz, L. Luke Vazul

Patent number: 6772448Abstract: A goggle resistant to fogging is provided. The goggle consists of a water wicking and thermal transfer face gasket combined with heat transfer inlets and outlets optimized for heat transfer to air flow through the goggle. With low airflow resistance in the vertically oriented inlets and outlets, the goggle ventilates by natural convection removing moisture and keeping the goggle from fogging. Simultaneously, the present goggle results in greater comfort for the user.Type: GrantFiled: December 12, 2002Date of Patent: August 10, 2004Assignee: Energy Related Devices, Inc.Inventors: Robert G.

Patent number: 6645651Abstract: A system of two fuel ampoules that can deliver a reactant by diffusion through one of the ampoule walls to the other, such that when said reactant enters the second ampoule, it reacts with another reactant in said second ampoule, making hydrogen gas as a product. Both ampoules are stored in a fuel impermeable container. These ampoules used with small low power fuel cells which need a steady controlled uniform delivery of vaporous fuel such hydrogen and alcohols. This fueling system provides a simple safe fuel interactive system for small hydrogen fuel cells that prevents inadvertent hydrogen production by any single ampoule being exposed to water or typical consumer environments.Type: GrantFiled: June 1, 2001Date of Patent: November 11, 2003Inventors: Robert G.

Patent number: 6544400Abstract: A hydrogen source system delivers a controlled fuel stream to applications, using wicking to control the contact between a mixture of NaBH4, NaOH and H2O and a hydrolyzing catalyst to create a feedback mechanism to automatically maintain a constant pressure production supply of hydrogen. A small compact device packaged for storage, the system operates in any orientation and is mobile. The system is a small portable packaged hydrogen generator for small fuel cells to power applications that are currently powered by batteries. These packaged devices have higher energy per unit mass, higher energy per unit volume, are more convenient for energy users, environmentally less harmful, and less expensive than conventional power sources.Type: GrantFiled: March 30, 2001Date of Patent: April 8, 2003Assignee: Manhattan Scientifics, Inc.Inventors: Robert G.
