Patent number: 7919290Abstract: The invention provides a method to decrease emission of carbon dioxide from combustion of fossil fuels or other hydrocarbons and to enhance the efficiency of methane production from anaerobic biodigesters. The invention involves feeding carbon dioxide from the exhaust gas of hydrocarbon fuel combustion to an anaerobic biodigester where biomass is anaerobically fermented to produce methane. Carbon dioxide is an electron acceptor for anaerobic fermentation, and thus some of the carbon dioxide is reduced to methane, which can again be used for fuel. In this way, at least a portion of the exhaust gas CO2 is recycled to form fuel methane instead of being released into the atmosphere. Thus, the net CO2 emission from burning a given amount of fossil fuel is decreased. Adding carbon dioxide to an anaerobic fermentation also increases the efficiency and amount of methane production in the fermentation.Type: GrantFiled: February 24, 2009Date of Patent: April 5, 2011Inventors: John D.

Publication number: 20020045245Abstract: An apparatus for growing anaerobic microorganisms is provided having a dish top that contains a sealing ring upon which the media surface in the dish bottom rests when the apparatus is inverted. The contact between the sealing ring and the media surface forms a seal that traps the gas in the headspace between the media surface and the inside of the dish top. A oxygen reducing agent can also be incorporated into the media together, in some instances, with a substrate which react with oxygen in the media and with oxygen in the headspace thereby creating an environment suitable for growing anaerobic, microaerophilic and facultative anaerobic microorganisms.Type: ApplicationFiled: March 19, 2001Publication date: April 18, 2002Applicant: Oxyrase, Inc.Inventors: James C.

Patent number: 6265210Abstract: Controlled atmosphere cabinet has enclosure (110;210) with means providing visibility (110F; 210F) of its interior from outside, gas supply (113-116, 212-216) for desired or target composition of internal atmosphere, controlled lock-type access (112) for manual introduction and removal of items, and hand/arm access port provision (111A, B; 211A, B) for manipulation of said samples in the cabinet. Gas supply associated control means (230-240) serves during use of the cabinet (other than normal atmosphere augmenting in use of the lock-type access) for additional gas supply further to correct or compensate for effects actually or potentially adverse to maintaining the desired or target internal atmosphere composition, via operator-actuated input means (121t, 123; 222) and/or means (122, 124, 139; 225) for sensing prescribed conditions to which the control means is responsive for said additional gas supply.Type: GrantFiled: March 8, 1999Date of Patent: July 24, 2001Assignee: Don Whitley Scientific LimitedInventors: Peter Silley, Michael John Annable

Patent number: 6177271Abstract: A laboratory incubator (10) having an improved temperature control assembly (14) that more effectively maintains the temperature within the incubator in a desired range and more accurately controls the rate of heat loss from the laboratory incubators as ambient temperatures rise. The incubator includes a housing (12) having an enclosed incubation chamber (18) therein; a heater (22) positioned within the housing for heating the chamber; a cooling device (24) positioned within the housing for cooling the walls of the housing; and a controller (26) for controlling the operation of the heater and the cooling device to maintain a temperature in the chamber within a set temperature range. The cooling device includes an electrically operated peltier device operable to both cool the chamber and to assist the heater in heating the chamber.Type: GrantFiled: April 19, 1999Date of Patent: January 23, 2001Assignee: SPX CorporationInventors: Charles G.
