    摘要： The invention contemplates a steam-surface condenser construction wherein an assembly of spaced tube sheets, associated tubes and water boxes is axially compliantly supported with respect to the condenser shell, and wherein the said assembly further includes elongate strain-proportioning mechanism extending between the tube sheets and effectively tying the water boxes to each other independently of tube-sheet connection via the tubes. The strain-proportioning mechanism may take the form of plural spaced elongate members which effectively span the assembly, these members being positioned in substantial alignment with the region of water-box connection to the respective tube sheets.

    摘要： An improved, pressure vented, wear ring assembly is herein described for use in rotary machinery having a substantial axial pressure gradient. A rotor shaft contacting element, in the form of a plastic wear ring, is mounted in a holding member to extend generally co-axially about the axis of rotation of the rotor member. The holding member substantially encloses all but the rotor engaging portion of the wear ring and is formed with pressure relieving apertures, or exhaust ports, to release high pressure fluid, trapped between opposing surfaces of the wear ring and the holder, to a low pressure region. An intermediate ring or liner is interposed between the wear ring and the holder member, which intermediate ring comprises a porous, nonextrudable member having a relatively high compressive strength. The porous member is operable to direct the trapped high pressure fluid axially, radially and circumferentially of the wear ring, to the exhaust ports formed in the holder, while maintaining the wear ring in a properly aligned, operational posture.

    摘要： 1. A screw pump for liquids comprising a pair of similar screw assemblies each of which includes a plurality of intermeshing screws and a housing having intersecting bores enclosing said screw assemblies and defining for both of said screw assemblies inlet and outlet openings in free continuous communication with the ends of said screw assemblies, said screw assemblies and said housing bores being of types producing theoretically, except for running clearances, continuous discharge of pumped liquid, means providing a common passage receiving liquid flow from both of said screw assemblies, and a common drive means for said screw assemblies operating both at the same speed, the corresponding screws of said respective assemblies being displaced in phase substantially 180* with respect to each other from the standpoint of repetitive phases of discharge operation thereby to effect at least partial cancellation of flow disturbances in said common passage.

    摘要： An internal combustion engine drives a reciprocating compressor installed with various flow control valves in a gas pipeline. A pneumatic system using logic elements and control boards controls the starting, running and stopping of the engine and compressor and the working of the valves either from a point at the site or from a remote point. There are several choices of the relative amount of control by an attendant or automatically and including automatic imposition of load and response to variations in load and also automatic response to anomalous or dangerous conditions.

    摘要： In order to reduce the tilting of the section of a ship''s shafting system which carries the main drive gear and thereby improve the load distribution between meshing gear teeth, a bearing system is provided comprising a pair of ordinary cylindrical journal bearings, one on either side of the main drive gear, and a pair of additional bearings, each located next to one of the cylindrical journal bearings. The latter bearings serve to provide a spring scale in the horizontal direction sufficient to reduce tilting of the main gear shaft section.
