  • Patent number: 12258872
    Abstract: A containment structure for a rotor includes a shroud and a shroud reinforcement. The shroud is coaxial with and partially surrounds the rotor and includes a tubular section, a transition section, and a flange section. The tubular section extends axially past a first side of the rotor. The transition section connects to the tubular section and is adjacent to a curved side of the rotor. The flange section connects to the transition section opposite the tubular section. The flange section extends radially past a radially outer side of the rotor. The shroud reinforcement is connected to a radially outer surface of the transition section. The shroud reinforcement encloses the transition section and includes a support scaffold and a reinforcing material. The support scaffold includes a series of geometric retaining features encircling a radially outer surface of the transition section. The reinforcing material couples to the support scaffold and restricts shroud radial expansion.

  • Publication number: 20250079930
    Abstract: A method for increasing stator cooling airflow in an air cooled electric motor is provided, wherein the air cooled electric motor includes a compressor outlet housing having a motor cavity separator wall and a separator plate defining a separator plate opening, wherein the compressor outlet housing defines a separator plate cavity and a compressor rotor back-face cavity configured to receive a back-face cavity airflow. The motor cavity separator wall separates the separator plate cavity from the compressor rotor back-face cavity and defines a motor cavity separator wall through-hole which communicates the separator plate cavity with the compressor rotor back-face cavity and a motor cooling housing including a motor cooling outlet structure which defines a stator outlet cavity, wherein the separator plate is disposed to separate the stator outlet cavity from the separator plate cavity.

  • Publication number: 20210221116
    Abstract: Lithographic printing plates are provided by imagewise exposing negative-working lithographic printing plate precursors having one or more radiation-sensitive imageable layers, followed by contacting with a processing solution that contains up to 10 weight % of one or more compounds represented by Structure (I) shown as follows: R1—C(?O)—N(R2)—R3 ??(I) wherein R1, R2, and R3 independently represent hydrogen or a substituted or unsubstituted hydrocarbon group, or two or three of R1, R2, and R3 are combined to form one or more cyclic rings, and the total number of carbon atoms in the Structure (I) molecule is at least 7 and up to and including 33. Both negative-working and positive-working lithographic precursors can be imaged and processed using this processing solution using one or more successive applications of the same or different processing solution. The processing solution can be derived from a corresponding processing solution concentrate that can also be used for replenishment.

  • Patent number: 10975770
    Abstract: A heat exchanging arrangement is integrated within a gas turbine engine case that at least partially encloses a gas turbine engine. The gas turbine engine has an upstream end and a downstream end which are defined by a core fluid flow through the gas turbine engine. The heat exchanging arrangement includes at least one flow passage defined within the gas turbine engine case having an inlet port and an outlet port. The at least one flow passage is configured to direct at least a portion of a fluid flowing through the gas turbine engine from between a downstream position and an upstream position while traveling between the inlet port and the outlet port.
