| 20110028296 | BOWL STRUCTURE FOR A CENTRIFUGAL SEPARATOR - A centrifuge concentrator bowl has feed deposited onto a base of the bowl and includes a plurality of recesses at axially spaced positions along a peripheral wall of the bowl. The peripheral wall is formed of a rigid metal skeleton frame of rings and upstanding support members on which is molded a urethane liner material to form an integral structure with the rings located at ribs between the recesses. A fluidization water injection system includes an outer container on the bowl, which also acts as a clamping assembly and a plurality of liquid entry openings through the peripheral wall at the base of the recesses allowing flexing of the peripheral wall in response to changes in pressure in the fluidizing liquid. The bowl is formed of separate sections defined by a bottom concave base section and the cast skeleton wall all clamped together to allow replacement of the separate parts. | 02-03-2011 |

| 20090308942 | Thermanator Thermal Insulation Retrofit Panel - A heating system for heating an interior room may include a radiator member for generating heat, a wall member being positioned in a space relationship to the radiator member and a panel member being positioned between the radiator member and the wall member. The panel member may include an attachment member to attach the panel member to the wall member, and the panel member may include an inclined surface. The panel member may include a horizontal surface, and the panel member may include an inclined surface and a horizontal surface. The inclined surface may extend to an edge of the horizontal surface, and the panel member may include a substantially flat back surface. The attachment member may be a layer of adhesive, and the attachment member may substantially cover a back surface of the panel member. The attachment member may only cover a portion of the back surface of the panel member. The panel member may encapsulate air for insulation. | 12-17-2009 |

| 20090289125 | Thermanator Radiator - A heating system for heating an interior room may include a radiator member for generating heat, a wall member being positioned in a space relationship to the radiator member; and a panel member being positioned between the radiator member and the wall member. The panel member may include an inclined surface, and the panel member may include a horizontal surface. The inclined surface may extend to an edge of the horizontal surface, and the panel member may include a substantially flat back surface. The panel member may be attached to the wall member by a first attachment device, and the panel member may be attached to the radiator member by a second attachment device. The second attachment device may be a hook device, and the second attachment device may detachably connect the radiator member to the panel member. | 11-26-2009 |
| 20100237056 | Thermal Insulation Energy Saver Device - A heating system for heating an interior room may include a radiator member for generating heat, a wall member being positioned in a space relationship to the radiator member and a device member being positioned between the radiator member and the wall member. The device member will have two inner radiant barriers of silver aluminized material protected by paint or lamination. The device member may include an attachment member to attach the device member to the wall member, and the device member may include an inclined surface. The device member may include a horizontal surface, and the device member may include an inclined surface and a horizontal surface. The inclined surface may extend to an edge of the horizontal surface, and the device member may include a substantially flat back surface. The attachment member may be a layer of adhesive, and the attachment member may cover the perimeter of the back surface of the device member. The attachment member may only cover a portion of the back surface of the panel member. The device member may encapsulate air for insulation. | 09-23-2010 |
