Granted: 2009-05-19
Abstract: A convection cooking appliance includes an oven cavity in communication with an air channel assembly incorporating a catalyst. The catalyst includes multiple stages defined by first and second, spaced honeycomb structures. The first honeycomb structure is arranged to initially vaporize the carbon cooking byproducts which then directed to the second honeycomb structure wherein the vaporized byproducts are broken down into carbon dioxide and water prior to being expelled from the catalyst. Between the first and second honeycomb structures is a gap which functions to create a turbulence for the delivery of the vapor to the second honeycomb structure.

Granted: 2012-11-27
Abstract: A frost plug adapter assembly having a locking mechanism that provides a positive capture through an existing frost plug aperture. A cylindrical body is engaged within a frost plug aperture and is maintained in place by a bolt, a locking element and a wing nut. The bolt is advantageously positioned through the cylindrical body with a bolt head at the outer end. The wing nut is screwed onto a threaded end of the bolt so that the wings engage channels of arms of the locking element to spread the arms until they contact an inner annulus of the frost plug aperture. The frost plug adapter assembly is also capable of providing access to engine fluid by providing channels through the inner end of the cylindrical body. The frost plug adapter assembly is easy to install and the locking mechanism prevents the assembly from falling out under severe conditions.

Granted: 2011-02-15
Abstract: A method for logging a wellbore includes actuating a positioning device to adjust the position of a module relative to a reference point or object such as a wellbore axis or proximally positioned downhole device. With respect to a wellbore (14), an exemplary positioning device (140A, 140B) can set the measurement tool (104A, 104B) such as an acoustic device to successive radial positions (e.g., substantial concentricity or substantial eccentricity relative to an axis of the wellbore). In one embodiment, the module includes a measurement tool to measure different parameters of interest (e.g., acoustic logging data, check-shot data measurement, bonding of cement to casing). With respect to an adjacent downhole device, the positioning device can provide a selected relative orientation (e.g., azimuth, inclination, radial displacement) between the module (102A, 102B) and the adjacent downhole device. The positioning device can also be adapted to apply a jarring force to a wall of the wellbore to free a downhole device.
