Patent number: 9095923
Abstract: A method of welding alloys having a ductility drop temperature range to limit strain-age cracking. The method involves the use of a welding device to weld a weld area of an article while maintaining temperatures throughout the weld area and a heat affected zone adjacent the weld area within a non-crack sensitive temperature range that is above a ductility drop temperature range of the alloy being welded. During welding, the temperatures of the weld area and the heat affected zone are predominantly controlled with heat input from the welding device. Once the welding has been terminated, the weld area and the heat affected zone are cooled from the non-crack sensitive temperature range through the ductility drop temperature range to a temperature below the ductility drop temperature range of the alloy.

The NM imaging system also includes an immobilization plate that is configured to be positioned between the first and second NM cameras and extend parallel to the camera surface of the first NM camera. The immobilization plate is movable to and from the camera surface of the first NM camera to compress the patient tissue, and the second NM camera is movable to and from the immobilization plate. The second NM camera is oriented with respect to a roll axis that extends parallel to the immobilization plate. The second NM camera is rotatable about the roll axis while the immobilization plate and the first NM camera have fixed positions with respect to each other with the patient tissue therebetween.

Abstract: Washing machine appliances and methods are provided. A washing machine appliance has a drum positioned within a tub, the drum defining a wash chamber for receipt of articles for washing, and an ozone generation system for directing ozonized water into tub. A method includes flowing ozonized water into the tub. The method further includes rotating the drum in a first gentle cycle including rotating the drum for a first predetermined rotation period and holding the drum generally stationary for a first predetermined exposure period. The method further includes rotating the drum in a second agitation cycle including rotating the drum for a second predetermined rotation period, the second predetermined rotation period longer than the first predetermined rotation period. The method further includes draining ozonized water from the tub of the washing machine appliance, and rotating the drum to extract ozonized water from the articles within the wash chamber.

Abstract: A converterless motor-driven pump system includes an off-grid prime mover. The prime mover includes a rotational driveshaft that operates in response to a throttle or fuel input controller to control a rotation speed of the prime mover driveshaft. Operation of the throttle or fuel input controller is based on desired output characteristics of a pumping load. One or more electric power generators are driven by the off-grid prime mover to generate AC or DC power on an electrical bus shared by a plurality of variable speed electric motors. A plurality of pumps is connected to a common manifold shared by the plurality of pumps. The plurality of pumps is driven by the plurality of variable speed electric motors to generate a desired wellhead pressure or pumping load flow rate via the shared common manifold.

Application number: 20150208999
Abstract: An imaging system is provided including a plurality of detector units and a controller. The plurality of detector units are distributed about a bore. The bore is configured to accept an object to be imaged, and the detector units are radially articulable within the bore. The controller is operably coupled to the plurality of detector units and configured to control the positioning of the detector units. The controller is configured to position an external group of the plurality of detector units at a predetermined intermediate position corresponding to a ring having a radius corresponding to a total number of detector units, and to position an internal group of the plurality of detector units radially inside the ring.
