Patent number: 10739014Abstract: An appliance comprising a firebox, a first air duct and a room air chimney. During operation of the appliance heated room air adjacent to a viewing pane or the screen and heated room air from the first air duct is received within the chimney. The heated air within the chimney rises toward an open upper end causing the chimney to draw additional room air from adjacent to the viewing pane or screen.Type: GrantFiled: February 23, 2018Date of Patent: August 11, 2020Assignee: Wolf Steel Ltd.Inventors: Wolfgang Schroeter, David Shulver, Richard Tjart, Clifford N. Lilley

Patent number: 9889420Abstract: A feed injector for a circulating fluid bed reactor is fitted with a discharge nozzle with a circular, radially notched discharge orifice to improve the surface-to-volume ratio of the spray pattern formed by the nozzle. The feed injector is useful for injecting fluids into various types of circulating fluid bed reactors in which good contact between the components of the fluidized bed and the injected fluid is required. It is particularly useful in fluid coking reactors.Type: GrantFiled: December 1, 2015Date of Patent: February 13, 2018Assignee: EXXONMOBIL RESEARCH AND ENGINEERING COMPANYInventors: Brian Allen Knapper, Christian Wolfgang Schroeter, Robert William Skwarok, Nicholas Prociw, Jennifer McMillan

Patent number: 7080472Abstract: A flame simulating apparatus to simulate flames emanating from a wood or fossil fuel burning fire. The flame simulating apparatus includes a light source, a light reflecting element, and a fire simulation screen. The light reflecting element produces a moving and generally random pattern of reflected light when light is cast upon it by the light source. The fire simulation screen has the image of a fire thereon and is positioned so that reflected light from the light reflecting element is cast upon its rear surface. The fire simulation screen includes at least one portion that is at least partially translucent such that light cast upon the partially translucent portion by the light reflecting element is diffused and at least partially passes through the translucent portion to present a moving flame image when viewed from a position in front of the fire simulation screen.Type: GrantFiled: November 23, 2004Date of Patent: July 25, 2006Assignee: Napoleon Systems and Develpements Inc.Inventors: Wolfgang Schroeter, Cliff Lilley, Jeremy Kurtin

Patent number: 5839428Abstract: An unvented fuel burning appliance that includes a firebox, a burner and a front door releasably securable to the firebox. The firebox has an open front and enclosed bottom, rear, side and top surfaces. The door has a central panel with a catalytic converter positioned on the upper portion of the central panel. Exhaust gases from the burner are directed through the catalytic converter prior to exiting the firebox such that the catalytic converter eliminates or reduces harmful or noxious gases and particulate material contained within the exhaust gases. Heat that is generated by the operation of the catalytic converter is substantially directed, by way of radiation and convection, outwardly through the front of the appliance to reduce heat generated and maintained at the top of the firebox and thereby reduce the heating of the top surface of the appliance.Type: GrantFiled: March 18, 1998Date of Patent: November 24, 1998Assignee: Napoleon Systems, Inc.Inventors: Wolfgang Schroeter, Cliff Lilley, Richard Tjart

Patent number: 5755154Abstract: A gas barbecue that has a housing having a generally rectangular shape with opposing side and end walls, an open interior, an open top, gas control means, a cooking grill, a primary burner assembly located below the cooking grill, and an upper radiant burner. The upper radiant burner is positioned above the cooking grill and includes a tube burner and a radiating means. The radiating means has a perforated mesh with the tube burner positioned beneath the perforated mesh such that heat generated by the tube burner passes through holes in the perforated mesh thereby heating the perforated mesh and causing the mesh to generate and direct infrared radiant heat into the open interior of the barbecue. The holes in the perforated mesh help to enhance the heating of the radiating means and assist in the radiation of infrared heat into the open interior of the barbecue.Type: GrantFiled: September 16, 1996Date of Patent: May 26, 1998Assignee: Napoleon Appliance CorporationInventors: Wolfgang Schroeter, Cliff Lilley, Steven Schwarz

Patent number: 5676048Abstract: A gas barbecue having a rectangular body, gas control means, a cooking grill, and a burner assembly. The burner assembly includes an elongate tube burner and a generally L-shaped tube burner having a primary tube member and a secondary tube member intersecting the primary tube member thereby forming the general L shape. The free end of the secondary tube member is positioned in close proximity to the elongate tube burner such that the ignition of the elongate tube burner causes cross-ignition of the L-shaped tube burner when gas is supplied thereto.Type: GrantFiled: September 16, 1996Date of Patent: October 14, 1997Assignee: Napolean Appliance CorporationInventors: Wolfgang Schroeter, Cliff Lilley, Steven Schwarz
