摘要： An integral seal for priming or maintaining the nozzles or orifices of an ink jet printhead in an ink jet printer. The ink jet printhead includes a plurality of ink ejecting orifices arranged on a surface of the printhead and includes a seal integral with the surface which surrounds the ink ejecting orifices. The seal member is located within a recess formed in the surface and has a contacting surface which can be recessed from the ink ejecting orifices so that cleaning operations of the surface which, for instance, use a wiping blade, are not impeded. A capping member on a maintenance station contacts and slightly compresses the seal member to provide an airtight seal during priming/maintenance operations.

摘要： A plasma arc torch used in underwater cutting is disclosed. The plasma arc torch includes a torch body having a front end of substantially cylindrical configuration, and an electrode supported by the torch body and defining a discharge end extending toward the front end. A nozzle is mounted on the front end of the torch body adjacent the front discharge end of the electrode, and has a bore through which plasma is ejected. A cylindrical support body is secured onto the outer surface of the torch body and extends in spaced relation from the torch body outer surface toward the front end and forms an annular opening. A cylindrical sleeve has a rear portion received within the annular opening of the cylindrical support body and extends in spaced relation along the front end of the torch body to define an annular air chamber extending along the front end and forming an annular outlet opening positioned adjacent the nozzle. A high velocity gas is injected into the annular air chamber. The high velocity gas swirls downward through the outlet opening for generating a protective air curtain for the plasma during underwater torch operation.

摘要： An ink jet printer is disclosed having a rotatable intermediate drum having a thermally conductive surface on which the ink droplets are printed from the printhead. The drum surface material is a suitable film forming silicone polymer having a high surface energy and surface roughness to prevent movement of the droplets after impact thereon. The printhead is located relative to the intermediate drum surface so that the ink droplets impact the drum surface with a large contact angle and the ink droplet image is transferred at a second location spaced from the printhead to minimize contaminating particles from the recording medium from reaching the printhead nozzles. The intermediate drum surface is heated to dehydrate the ink droplets prior to transfer from the intermediate drum to the recording medium. The silicone polymer coating enables substantially complete transfer of the dehydrated droplets to the recording medium, so that subsequent removal of the residual ink from the drum by a cleaning system is eliminated.

摘要： A preform is made by casting a copolyester polymer elastomer into a block. While the block is solidifying, pressure is supplied to the central portion thereof. After a block is formed, it is annealed and a precompression force is applied thereto sufficient to compress the block to an extent greater than thirty percent of the original dimension of the block as measured parallel to the precompression force. In one embodiment a cushioning unit using the block is made by placing a pair of multi-apertured metal plates on opposite sides of the block with projections on the plates extending against the block and applying a second precompression force to the block and plates sufficient to cause the copolyester polymer elastomer to flow into the apertures in the plates and form a mechanical bond between the block and the plates.

摘要： A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein, are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Sample flow rate is important in the jet fuel thermal oxidation test. Current practice requires manual drop counting or flow confirmation with the use of volumetric glassware. An apparatus is described to precisely measure the flow rate and automatically perform flow rate check using a drip rate method and/or volumetric method.

摘要： A motion restoring intervertebral prosthesis for replacing a failed or partially failed natural disc comprises two components defining an imaginary longitudinal axis generally aligned with the spinal axis when installed, the components having vertebral body engaging surfaces on one side and mating articulating surfaces on the other side, with peripheral rims encircling the articulating surfaces. The articulating surfaces accommodate rotational motion about the longitudinal axis and limited pivotal motion about the A/P and M/L planes. The rims are arranged to contact and limit the pivotal motion between the components to about +/−6° and preferably +/−4° in both directions in the M/L plane and in the A/P plane in the forward direction. Optionally, the encircling rims allow pivotal action of about 20° to 30° in the A/P plane in the rearward direction.

摘要： A fluid ejecting method and system include one or more fluid ejectors within a fluid ejector frame and an interposer frame and movably mounted upon a fluid ejector carriage. The fluid ejector carriage traverses across a recording medium for placing swaths of fluid droplets upon the recording medium. A biasing structure urges the fluid ejector frame to a first position to obtain highly accurate and repeatable placement of fluid droplets when the fluid ejector frame is in the first position. A second position of the fluid ejector frame is achieved by energizing a position actuator to move the fluid ejector frame from the first position to the second position to obtain highly accurate and repeatable placement of fluid droplets when the fluid ejector frame is in the second position. The recording medium is advanced separately upon completing a set of at least one swath of fluid droplets.
