  • Publication number: 20080288059
    Abstract: Expandable intraluminal stents are provided as well their method of manufacture. These stents are made of metal, the metal characterized by a desired porosity, with a drug compressed into the pores of the stent. The stents are formed by subjecting one or more powdered metals in a die cavity to a pressure treatment followed by a heat treatment. The metal may be cast directly in a stent-like form or cast into sheets or tubes from which the inventive stents are produced. The so-formed porous metal stent is then loaded with one or more drugs.

  • Publication number: 20080087752
    Abstract: A machine for distributing blowing insulation including a shredding chamber configured to shred and pick apart the blowing insulation. The shredding chamber includes a plurality of low speed shredders, an agitator and a discharge mechanism. The agitator is mounted for rotation and rotates toward the discharge mechanism. The discharge mechanism includes a side inlet configured to receive the blowing insulation from the agitator. A baffle is disposed between the agitator and the discharge mechanism. The baffle is configured to partially obstruct the side inlet of the discharge mechanism. The baffle allows finely shredded blowing insulation to enter the side inlet of the discharge mechanism and directs heavy clumps of blowing insulation past the side inlet of the discharge mechanism for eventual recycling into the low speed shredders.

  • Patent number: 6923198
    Abstract: A fully draining valve including an upper valve portion and a lower valve portion. The lower valve body has an integral weir, which in conjunction with a resilient diaphragm, defines a fluid passage. The weir axis is sloped from a horizontal plane. A first duct axis is sloped downwardly away from the weir and sloped from the horizontal plane. A second duct axis is sloped downwardly away from the weir and sloped from the horizontal plane. A third duct axis is oriented downwardly away from the weir and substantially parallel to a vertical axis such that substantially all liquid from within the fluid passage drains from the valve by gravity.

  • Patent number: 6854657
    Abstract: A smart card package includes two on-board batteries for providing uninterrupted power to a programmed, volatile memory unit. The first battery is a non-rechargeable battery with sufficient capacity to provide power to the volatile on-board memory during an initial storage period between programming the memory and deployment of the smart card. This initial storage period may be, for example, approximately two years. The second battery is a rechargeable battery that will be charged by the host device in which the smart card is deployed. The second, rechargeable battery can provide power to the volatile memory throughout the life of the card, after the first, non-rechargeable battery is dead. Specifically, the second, rechargeable battery can provide power to the non-volatile memory when needed during, for example, any subsequent storage period or during movement of the smart card between host devices.

  • Publication number: 20040134592
    Abstract: A conduction welding apparatus and method for bonding abutted thermal plastic tubular end portions is particularly suitable for welding PFA. In a preferred embodiment, a folding weld head embraces the abutted the tubular end portions to be welded, each tubular end portion including a flange spaced from the surfaces to be joined. The weld head includes means for securing the flanges within the weld head and further include bias means. The bias means provide an inward axial bias on the adjoined tubular end portions when the tubular end portions are displaced axially outward from the weld head due to the expansion of the plastic during the weld process. The bias means in a preferred embodiment is substantially inoperative prior to the weld and provides bias, or a substantial increase in bias, when the flanges are displaced due to the expansion of the molten PFA during the weld process.

  • Patent number: 6663034
    Abstract: A data storage tape cartridge is disclosed including a housing, a single tape reel, a storage tape, and a leader block. The housing includes a front, a back, a first side, a second side, a top, and a bottom. Further, the housing forms a leader block window, a lateral datum pad, and a longitudinal datum pad. The leader block window is formed at a corner defined by the front and the first side. The lateral datum pad is formed in the top. Finally, the longitudinal datum pad is formed in the front. The single tape reel is rotatably maintained within the housing. The storage tape is wrapped about the tape reel. The leader block is coupled to a leading end of the storage tape and is selectively secured to the housing at the leader block window. With this configuration, the lateral datum pad is configured to identify a top-to-bottom position of the tape reel.
