  • Patent number: 5964388
    Abstract: Coin roll wrapper cutter for assisting in removing the wrapper from a roll of coins. The wrapper cutter has a cutter body which is generally an elongated cylinder. A roll of coins secured by a wrapper is pushed into the top of the cylinder and the side of the roll is contacted by a sharp knife which forms an elongated slit along the wrapper. The slit wrapper easily permits the removal of the coins. Preferably, the knife is spring loaded and moves out sufficiently so that coin rolls of different denominations can be opened by a single size of coin roll wrapper cutter.

  • Patent number: 5964703
    Abstract: A medical extravasation device has an electrode patch that can attach to the skin for sensing electrical information. Tissue impedance is calculated from the electrode patch signals. The patch has elongate pick-up electrodes inboard of elongate energizing electrodes. The measuring zone determined by the elongate space between the pick-up electrodes enhances sensitivity and specificity. The presence of an extravasation is determined by interpreting the tissue impedance measurement. The method for determining the extravasation includes a first step of determining a pre-injection baseline measurement of the tissue impedance. Then, the tissue impedance is monitored during the procedure itself. A predetermined amount of change in tissue impedance is determined to indicate an extravasation.

  • Patent number: 5965380
    Abstract: A small diameter flexible electrode designed for subcutaneous in vivo amperometric monitoring of glucose is described. The electrode is designed to allow "one-point" in vivo calibration, i.e., to have zero output current at zero glucose concentration, even in the presence of other electroreactive species of serum or blood. The electrode is preferably three or four-layered, with the layers serially deposited within a recess upon the tip of a polyamide insulated gold wire. A first glucose concentration-to-current transducing layer is overcoated with an electrically insulating and glucose flux limiting layer (second layer) on which, optionally, an immobilized interference-eliminating horseradish peroxidase based film is deposited (third layer). An outer (fourth) layer is biocompatible.

  • Patent number: 5961795
    Abstract: The invention relates to an electrochemical cell which has an electrode, a membrane disposed in contact with one side of the electrode, and a resilient flow field disposed on the other side of the electrode. The resilient flow field provides uniform electrical contact with the electrode. Such a flow field is preferably an elastomer, which can be be made by molding techniques, thereby decreasing the cost and increasing the ease with which such a flow field may be manufactured. The resilient flow field of the present invention is particularly useful in converting anhydrous hydrogen halide directly to essentially dry halogen gas, such as anhydrous hydrogen chloride to chlorine gas, although it may be used in a cell which converts aqueous reactants.

  • Patent number: 5962727
    Abstract: An improved method for manufacturing diesters of polytetramethylene ethers involving the polymerization of tetrahydrofuran (THF) optionally with one or more comonomers (e.g., 3-methyl THF, ethylene oxide, propylene oxide, or the like) utilizing a solid acid catalyst (e.g., Nafion.RTM.) and a carboxylic acid with carboxylic acid anhydride (e.g., acetic acid with acetic anhydride) as molecular weight control agents wherein setting the pressure of the reactor while simultaneously achieving removal of the heat of reaction by operating under solvent/monomer evaporative reaction conditions effectively controls the reaction temperature. Such a process is useful in producing high purity commercial grade PTMEA that advantageously avoids problems caused by the high heat of reaction when such a process is scaled up to commercial level.
