Controlling a productivity application to integrate a revision stream and an undo stack to perform out of order undo operations
A computing system runs a productivity application that maintains an integrated, time ordered revision/undo stack. Entries in the revision/undo stack identify revision operations that a user has made to a document and corresponding undo operations that can be executed to undo the revision operation. The computing system detects an undo input indicative of a user actuating un undo actuator to undo a previous operation, that is prior to a most current operation that the user has performed. An operational transform system identifies an undo operation in the undo stack, corresponding to the revision that the user selected in the revision/undo stack. The operational transform system traverses the revision/undo stack to identify subsequent operations that were performed subsequent to the previous operation, and identifies one or more transforms to be applied to the undo operation based upon the identified subsequent operations. The operational transform system then transforms the undo operation, using the transformation function, and applies the transformed undo operation to the document. |

Vapor chamber water-filling section sealing structure
A vapor chamber water-filling section sealing structure. The vapor chamber water-filling section sealing structure includes a main body and a capillary structure. The main body has a first plate body and a second plate body, which are correspondingly mated with each other to together define an airtight chamber and a water-filling section. A flange is disposed along an outer periphery of the main body. The water-filling section has a water-filling notch and a water-filling passage. Two ends of the water-filling passage are respectively connected with the flange and the water-filling notch to communicate with the airtight chamber. A portion of the water-filling passage that is connected with the flange is pressed to have a height equal to the height of the flange or lower than the height of the flange. The capillary structure is disposed in the airtight chamber of the main body. |

Shell and tube heat exchangers
A heat exchanger in one aspect includes a longitudinal shell and a transverse shell oriented transversely thereto. A J-shaped tube bundle carrying a tube-side fluid extends through the longitudinal and transverse shells from a first tubesheet in the longitudinal shell to a second tubesheet in the transverse shell. The first and second tubesheets are oriented perpendicular to each other. In a related aspect a dual heat exchanger unit includes a first longitudinal shell, a second longitudinal shell, and a common transverse shell extending transversely between and fluidly coupled to the longitudinal shells. The longitudinal shells may be parallel to each other. The shells are fluidly coupled directly together to form a common shell-side space between pairs of inlet and outlet tubesheets. A pair of J-shaped tube bundles is disposed in the dual heat exchanger unit for heating two tube-side fluids. |

Heat exchanger with multistaged cooling
A heat exchanger for abating compounds produced in semiconductor processes. When hot effluent flows into the heat exchanger, a coolant can be flowed to walls of a fluid heat exchanging surface within the heat exchanger. The heat exchanging surface can include a plurality of channel regions which creates a multi stage cross flow path for the hot effluent to flow down the heat exchanger. This flow path forces the hot effluent to hit the cold walls of the fluid heat exchanging surface, significantly cooling the effluent and preventing it from flowing directly into the vacuum pumps and causing heat damage. Embodiments described herein also relate to methods of forming a heat exchanger. The heat exchanger can be created by sequentially depositing layers of thermally conductive material on surfaces using 3-D printing, creating a much smaller footprint and reducing costs. |
