Abstract: A system and method for controlling bending modes of a rotor assembly is disclosed. The rotor assembly can be supported by one or more bearings in an integrated machine. The method can include accelerating the rotor assembly to a first rotational speed via a first torsional force applied to the drive shaft and then removing the first torsional force. The method can also include obtaining first measurements of the rotational speed and frequency of one or more bending modes of the rotor assembly during a first rotary machine coast down period from the first rotational speed. The process can be repeated to determine a relationship between rotational speed, bending mode frequency, and gain. The one or more bearings can then be controlled based on the measurements and the relationship. The system can have one or more processors or controllers to implement the method.

Abstract: A power connector for an electric motor is disclosed. The power connector includes a flange, a conductor rod, and an insulation sleeve. The conductor rod includes a first portion extending in a first direction from the flange and a second portion extending from the flange in a second direction, opposite the first direction. The second portion includes a lead wire connection end distal to the flange. The insulation sleeve covers the second portion from the flange to the lead wire connection end. The insulation sleeve includes a sleeve outer surface, and a sealing rib extending outward from the sleeve outer surface.

Abstract: A method forming a metallic structure having two or more portions is provided. The method can include providing a first layer of metal-forming material and then applying energy of a first power level to a first area of the first layer of metal-forming material to form a first portion of the metallic structure having a first density. Energy of a second power level can then be applied to a second area of the first layer of metal-forming material to form a second portion of the metallic structure having a second density. A second layer of the metal-forming material can be applied on top of the first portion and the second portion. The energy of the first power level can be applied to a first area of the second layer of metal-forming material and the energy of the second power level can be applied to a second area of the second layer to form the metallic structure.

Abstract: This invention discloses 3-aminobenzamide derivatives as ?-lactam antibiotic adjuvants of chemical formula (I), processes for preparing them and their use. The derivatives can act as ?-lactam antibiotic adjuvants for the treatment of methicillin-resistant staphylococcal infections.

Abstract: The present invention relates to a downhole support device (100) for use in a wellbore and which is adapted to be run into the wellbore through an elongate member string (2) such as on a string of tubulars, a coiled tubing string or a slickline. The downhole support device comprises an inflatable element (102), which in use is adapted to be selectively connectable to the elongate member string and is further adapted to apply a biasing force in the direction of the wellbore walls. The inflatable element has an inlet (104) for receiving fluid and/or fluidized solids. The support device is further adapted to be selectively disconnectable from the elongate member string.

Abstract: A method for controlling a gas compressor is disclosed. The method includes communicating feedback data about two magnetic bearings to a computer including a multi-core processor via a communication link. The method also includes processing the feedback data about the two magnetic bearings where the feedback data for each of the two magnetic bearings is processed on separate cores of the multi-core processor in parallel and issuing a bearing control command to each of the two magnetic bearings in response to the feedback data. The method further includes communicating the bearing control commands to the two magnetic bearings from the computer via the communication link.

Abstract: An electric motor for a rotary machine is disclosed. The electric motor includes a first lamination section and a second lamination section radially spaced apart from a driver shaft forming a first air gap and a second air gap respectively. The second lamination section is axially spaced apart from the first lamination section forming an air gap cooling outlet there between. The electric motor also includes motor windings extending through the first lamination section and the second lamination section, and across the air gap cooling outlet in circumferential groups. A winding shield is located around each of the circumferential groups of the motor windings.
