Publication number: 20080198524Abstract: The subject application relates to a gas arrestor system(s) and/or methodology that facilitate sensing and shutting down a gas-burning appliance via a circuit that can perform both functions. In particular, the system and method can detect specific gases and at specific concentration levels by way of a sensory-power circuit. The circuit performs vapor detection and provides power to various ignition-related portions of the appliance. When gas or gas vapors are detected in the ambient air of the circuit and satisfy a threshold for that particular type of vapor, the circuit is shorted which results in a power loss to at least the ignition-related portions of the appliance. As a result, undesirable ignition of such vapors is mitigated.Type: ApplicationFiled: February 16, 2007Publication date: August 21, 2008Applicant: DOMETIC CORPORATIONInventors: PATRICK N.

Patent number: 7412837Abstract: The invention relates to a method for controlling a running time of an absorption refrigerating system of an absorption refrigerator, which absorption refrigerator comprises two differently tempered refrigerator compartments. The method comprises the steps of: monitoring the temperature in a first compartment; activating the refrigerating system when the temperature sensed in the first compartment exceeds a predetermined value; de-activating the refrigerating system when a cut-out temperature is reached; monitoring the time period during which the absorption refrigerating system is turned off; and supplying heat to the first refrigerator compartment, when the time period exceeds a predetermined time period. The invention also relates to a microcontroller, computer program product and to an absorption refrigerator comprising means for performing the inventive method.Type: GrantFiled: February 23, 2006Date of Patent: August 19, 2008Assignee: Dometic Sweden ABInventors: Arne Karlsson, Carl Lindhagen, Fredrik Reithe

Patent number: 7410804Abstract: A process of forming an array of powder samples arranged in predefined locations where all samples have a flat surface in a common plane has been developed. A main support having at least N perforations from a first surface of the main support through a second surface of the main support in predefined locations. The main support is equipped with a flat support temporarily attached to its first surface. All samples are loaded simultaneously. A flat surface of each sample, where the flat surfaces are a common plane, is formed by forcing the samples within the perforations against the flat support. The samples are retained in position within the perforations against the flat support using at least one cover. The flat surfaces of the samples are in predefined locations and are all in a common plane.Type: GrantFiled: August 12, 2004Date of Patent: August 12, 2008Assignee: UOP LLCInventors: Rune Wendelbo, Duncan E.

Patent number: 7288411Abstract: A process for simultaneously testing a plurality of catalysts using combinatorial chemistry has been developed. The process involves containing the plurality of catalysts in an array of parallel reactors with each reactor containing a bed of catalyst. Each bed of catalyst is then simultaneously contacted, at reaction conditions, with a reactant to form an effluent of each reactor. The reactant or an inert fluid is at a space velocity sufficient to fluidize the catalyst beds. Each of the effluents is analyzed.Type: GrantFiled: August 27, 2003Date of Patent: October 30, 2007Assignee: UOP LLCInventors: Duncan E. Akporiaye, Arne Karlsson, Ivar M. Dahl, Rune Wendelbo, Kurt M.
