Abstract: A syringe includes a syringe body having a syringe barrel for receiving and administering a medicament, a hollow needle fluidly communicating with the syringe barrel, and a needle adapter disposed on the syringe body. An outer diameter of the needle adapter is wider than an outer diameter of the syringe barrel, and a distal surface of the needle adapter is substantially flat. The needle adapter facilitates a flush alignment of the distal surface of the needle adapter with at least one of a vial stopper and a vial stopper holder of a medicament vial to ensure that a tip of the needle is properly inserted into the vial to aspirate the medicament within the vial.

Abstract: The present inventive apparatus relates generally to the field heat reflective radiant barriers that may be installed on a structure without the need to simultaneously replace rigid construction deck panels or roofing felt. The heat reflective radiant barrier is for use as a part of the outer protective water-shedding materials of a building and is substantially shingle-shaped. The heat reflective radiant barrier may be flexible or rigid.

Abstract: A nickel-base alloy that exhibits a desirable balance of mechanical properties, environmental properties, and microstructural stability suitable for gas turbine engine applications. The nickel-base alloy is in the form of a single-crystal casting consisting of, by weight, 5.75% to 6.5% aluminum, 4% to 5% tantalum, 2% to 6% chromium, 5.5% to 7% tungsten, 1.5% to 3% molybdenum, 4% to 5% rhenium, up to 1.0% niobium, 10% to 16% cobalt, up to 1% titanium, 0.01% to 0.05% carbon, up to 0.005% boron, up to 0.01% yttrium, 0.5% to 1.0% hafnium, the balance nickel and incidental impurities. The alloy has a density of not more than 0.320 lbs/in3 (about 8.87 g/cm3), and contains a combined amount of aluminum, tungsten, molybdenum, niobium, titanium, and hafnium specified relative to the combined amount of tantalum and rhenium.

Abstract: A turbine engine combustor member, for example a deflector including an inner surface at a combustor interior and an outer surface away from such interior includes a body of a high temperature alloy having properties combining resistance to hot corrosion and oxidation to avoid coating the outer surface. In one embodiment, the inner surface includes an environmental resistant coating comprising a ceramic-base thermal barrier coating. In some forms such coating includes an inner coating including Al under the ceramic-base coating. In another embodiment, the member includes air cooling passages and is substantially uncoated. Provision of such a member enables complete combustor assembly including a plurality of members and then coating all inner surfaces concurrently rather than individually before assembly.

Abstract: A superalloy article has a composition consisting essentially of, in weight percent, from about 4 to about 12 percent cobalt, from about 3.5 to about 7 percent tungsten, from about 2 to about 9 percent chromium, from about 0.5 to about 4.5 percent tantalum, from about 5.5 to about 7.5 percent aluminum, from 0 to about 5.5 percent rhenium, from about 0.1 to about 1.2 percent titanium, from 0 to about 3 percent molybdenum, from 0 to about 3 percent ruthenium, from about 0.5 to about 2 percent columbium, about 0.01 percent maximum boron, about 0.07 percent maximum carbon, from about 0.3 to about 1 percent hafnium, about 0.01 percent maximum zirconium, about 0.03 percent maximum yttrium, from 0 to about 0.5 percent vanadium, about 0.01 percent maximum cerium, and about 0.01 percent maximum lanthanum, balance nickel and impurity elements. The article is preferably substantially a single crystal or oriented polycrystal in a shape such as a gas turbine blade.

Abstract: An inkjet consumable cartridge having an inkjet cartridge having nozzles. The inkjet consumable cartridge also has an inkjet cartridge holding device for holding the inkjet cartridge, a cap configured to interface with the inkjet cartridge, and a cap actuator that, when actuated, moves the cap from a position where the cap does not interface with the inkjet cartridge to a position where the cap interfaces with the inkjet cartridge sealingly covering the nozzles. Furthermore, the consumable cartridge is removable from a printer as a self-contained unit.

Abstract: A modular duplex media handling system is installable for use with a print recording system having a simplex media handling system. During first side printing a media sheet is fed along a first media path in the simplex system from feed rollers to metering rollers and into a print zone. After first side printing and prior to releasing the media sheet, the metering rollers feed the media sheet back along the first media path to the feed rollers. The feed rollers in turn feed the media sheet completely into the duplex module where the media moves along a loop path (in effect flipping the media sheet). The media sheet then is fed back to the feed rollers and along the first media path for second side printing. A humidity sensor in the duplex module signals to the print recording system whether the duplex handling system is installed.

Abstract: A reciprocating piston pump provides pulsation free delivery of liquid. It is suitable for use in compact environments or for the delivery of small amounts of liquid, as in chromatographic analysis devices. The pump includes two pistons with pumping chambers that are alternately connected to inflow and outflow lines through a control valve. The control valve moves between a first position in which inflow is directed to the first piston chamber and outflow to the second piston chamber, and a second position in which outflow is directed to the first piston chamber and inflow is directed to the second piston chamber. Each outflow pulse from the piston is sustained longer than each inflow pulse, and the outflow pulses are staggered and partially superimposed to provide substantially pulsation free delivery of liquid from the pump. A rotating cam moves the pistons of the pumps and the control valve between their operating positions described above.

Abstract: A pump motor controller for making pump motor speed independent of fluid pressure at the inlet and outlet of the pump. A first embodiment employs feedback to cause pump motor speed to converge to a desired speed established with a reference input signal. Based on this feedback, forward and reverse drive amplifiers in the first embodiment cause the pump motor speed to track the desired speed. A second embodiment employs a controller that produces drive signals to a stepper motor in proportion to a reference frequency. The controller and stepper motor in the second embodiment achieve speed control at low speeds without the use of a feedback control loop.
