摘要: Electrostatic transducers (10, 100) for generating and/or sensing percussion waves have an internal rigid unitary element comprising an insulating sleeve (17, 117), an electrode backplate (21, 121) situated within the sleeve (17, 117), and a dielectric layer (22, 122) which secures the electrode backplate (21, 121) within the sleeve (17, 117). The dielectric layer (22, 122) is a generally continuous layer and has support fingers (24, 124) protruding outwardly away from the electrode backplate (21, 121) for supporting an electrode diaphragm (26, 126), preferably a durable metal foil. The electrode diaphragm (26, 126) may be hermetically sealed to a housing (111), which encloses the unitary element so that the transducers (10, 100) are better suited for harsh, extreme high/low temperature, and/or extreme high/low pressure environments. Furthermore, the interior region (32, 132) of the transducer (10, 100) can be evacuated via a throughway (31, 131) so that the transducer power can be increased.

摘要: The pickup bed tool tray apparatus provides a movable, motorized tray that fits between the inner sides of a pickup bed, just below the bed top. The apparatus is therefore not in the way of storing or carrying anything in the bed. By using the control, the tray may be moved fore and aft, as needed, to best access tools and other equipment that may be carried in the tray.

摘要: An acoustic transducer for measuring a property of a fluid includes an acoustic pulse generator and buffer assembly. The buffer assembly is between the pulse generator and the fluid. The buffer assembly is composed of a core and a sleeve shrink fitted over the core to form a cladding layer. The cladding layer reduces dispersion of the acoustic pulses traveling through the core.

摘要: A page description language (PDL) is selected for use by a device driver. A PDL is assigned to an application. The assignment of the PDL to the application may then be stored to an index such as a registry or to a file. The device driver is loaded from within the application. The application, from within which the device driver was loaded, is discovered. The application from within which the device driver was loaded may be discovered by examining the host operating environment upon which the application is operating. The PDL assigned to the application is selected for use by the device driver. The PDL assigned to the application may be selected by searching the index to find the PDL assignment for the application and extracting from the assignment the PDL assigned to the application.

摘要: A flow conditioning plate for interposition in a flow line has a pattern of apertures which introduces a flow irregularity characteristic of a commonly encountered irregular flow in a plant, such as the disturbance introduced by one or more junctions or fittings in the upstream flow path. The apertures may introduce a specific flow distribution, asymmetry of flow profile or swirl component, and these may be tuned to simulate a plant condition that occurs downstream of one or more bends, elbows or T junctions. The disturbance persists, or evolves in a known way for a well defined distance along the flow path to simulate field flow conditions, and a flow meter is tested or calibrated in the disturbed segment, preferably at a defined position, under known flow to produce a calibration table. The meter may then be later installed to measure the irregular flow in an unconditioned flow line at a plant. This allows a meter factor or multiple weighting algorithm to be quickly ascertained and programmed to adapt a meter to an intended plant having known configuration involving complex or disturbed flow paths and irregular flow conditions, and the method of calibration extends the use of clamp-on metering systems to process measurement needs at many accessible conduits and segments in existing plants that carry unsettled or disturbed flows.

摘要: A radiator assembly for a locomotive is provided. The locomotive has an engine for driving the locomotive and a cooling water system for circulating cooling water through the engine to operatively control the temperature of the engine, the assembly including a radiator in fluid communication with the cooling system and a fan which selectively draws air through the radiator and into the inlet of the fan. The radiator assembly also includes a shutter for selectively controlling the drawn air flow through the radiator and a control system operatively attached to the shutter for actuating the shutter to control the drawn air flow in dependence on a determined control temperature. The control assembly is also operatively attached to the fan to select and set the speed of the fan in dependence on the determined control temperature.

摘要: A two-piece nestable cup-like container comprising a continuous side wall having an open upper end and includes a recessed bottom. The side wall is formed from a single double ended sheet of a heat-shrinkable thermoplastic material. The ends of the sheet are joined to one another along a liquid-tight seam. The side wall extends downwardly from a point near the open mouth of the upper end of the container to a point near the bottom and is thereafter folded at its lower edge upwardly to form a double wall portion and a radially inwardly extending annular portion that underlies a separate bottom member that is sealingly joined to the radially inwardly extending portion on the bottom edge of the side wall. In accordance with the method and apparatus, a sleeve made from the sheet by joining the ends is heat shrunk on a mandrel and the free edge at the lower portion of the side wall is caused to shrink inwardly. Opposed shaping members are moved toward one another while the sheet is at an appropriate temperature for shrinking and forming to define the doubled wall edge and to the heat seal the bottom member to the radially inwardly extending portion.

摘要: A device for forming a rolled rim at the unrimmed mouth of the body of a container having a body which is fabricated from a sheet of an expanded thermoplastic material, the device including a first member with a first annular rim-forming surface, and a second member which is reciprocable relative to the first member. The second member has a second annular rim-forming surface which forms a generally closed rim-forming chamber with the first annular rim-forming surface when the second member is in a first position relative to the first member, the second member being reciprocable to a second position in which the first annular surface and the second annular surface are separated to permit the withdrawal of a container with a rolled rim at the mouth from the first member. The device further includes a transfer mechanism for inserting a container with an unrimmed mouth over a frustoconical portion of the first member to position such container to have a rim rolled in the mouth thereof in such rim-forming chamber and to withdraw a container with a rolled rim at the mouth from the first member. The rim-forming chamber is heated and there is no relative rotation between the rim-forming chamber and the container during the forming of a rolled rim in the container.

摘要: A flow conditioner includes a body composed of an array of vanes generally parallel to the direction of fluid flow. The vanes create a plurality of chambers to effectively reduce large scale vortices in the flow. The vanes have surfaces with perforations to allow pressure regulation between chambers to effectively reduce asymmetric flow and reduce drag. Additional preferred features include an acoustic choke created by a reduction in cross-sectional flow area at the entrance and the exit of the flow conditioner with circular plates. The plates have rough edges to increase production of micro-vortices.
