  • Patent number: 5855975
    Abstract: A resinous film at least partially formulated from a recycled resin and containing a vapor phase corrosion inhibitor. One embodiment of the invention is a single layer film which is formulated from three components. The first component is a recycled resin such as polyethylene, the second component is a fresh resin identical to the first, and the third component is a vapor phase anti-corrosion agent. Multi-layer films are also included. The films emit the anti-corrosion agent over a period of time to thereby protect items encased by the film.

  • Patent number: 5855594
    Abstract: A cardiac pacing and sensing system includes a body implantable unit for generating tissue stimulation pulses and manipulating information based on sensed signals, and a catheter for transmitting pulses from the unit to a pacing electrode adjacent myocardial tissue. The unit incorporates circuitry for generating response values, one associated with each stimulation pulse, based on a predetermined characteristic or parameter of the signals evoked by the pulses. To evaluate the efficacy of the parameter in distinguishing capture versus non-capture, the stimulation pulses are generated according to a protocol of high energy pulses guaranteed to effect capture interspersed with low energy pulses guaranteed not to effect capture. Data, accumulated and sorted into separate "capture" and "non-capture" sets, provides respective capture and non-capture composite values.

  • Patent number: 5855559
    Abstract: An instrument for achieving rapid hemostasis at the conclusion of a catheterization procedure comprising a hemostatic agent injection device for use with a conventional introducer sheath used to gain access to the blood vessel. The injection device includes an elongated tubular member having ejection ports proximate its distal end. A hub member is located on the proximal end of the tubular member and includes an elongated groove or track located in its surface with a transparent cover. The enclosed track is in fluid communication with the lumen extending through the tubular member. After the catheterization procedure, the instrument is inserted into the introducer sheath. Blood flows into the lumen of the device and into the enclosed track. The leading edge of the blood pulsates within the enclosed track, clearly indicating that the ports are located in the blood vessel and subjected to variations in blood pressure.

  • Patent number: 5851139
    Abstract: An improved cutting head for a water jet cutting assembly utilizing water or other liquid medium at ultra high pressure, with the cutting head including an assembly with an elongated body having a central bore along its axis and including a delivery nozzle at the distal end of the assembly. Alignment of the components is maintained by incorporating a process of manufacture which utilizes the formation of a single bore extending through the body so as to both form and maintain axial alignment of the components. The arrangement is further characterized by having mating surfaces which are free of gaskets or other packing material, thereby establishing, maintaining, and preserving proper axial alignment of components.

  • Patent number: 5851100
    Abstract: A refuse and/or collection vehicle having an automated container handling mechanism that may automatically lift and dump a container into a charging hopper of the vehicle. A microprocessor controls the extension and lift of the container handling mechanism and analyzes the output voltage of potentiometers coupled to the container handling mechanism to thereby coordinate actuation of the container handling mechanism and smoothly pick up the container from the curbside, dump the container in the charging hopper, and return the container to the same position on the curbside but above the ground a predetermined distance.

  • Patent number: 5852244
    Abstract: A non-contaminating pressure transducer module having an isolation member is disclosed. The isolation member isolates a pressure sensor within the transducer module from exposure to fluids flowing through a conduit in the module. The transducer module may be positioned in-line within a fluid flow circuit carrying corrosive materials, wherein the pressure transducer module produces a control signal proportional to either a gauge pressure or an absolute pressure of the fluid flow circuit. The pressure transducer module of the present invention also avoids the introduction of particulate, unwanted ions, or vapors into the flow circuit.

  • Patent number: 5848574
    Abstract: A multi-hull watercraft, such as a catamaran or trimaran is constructed to facilitate the righting thereof following a capsize. By providing a pivot connection between the hulls and the cross-members, in accordance with one method, it is possible to right the capsized vehicle by piecemeal rotation of the hulls through 180.degree. from an inverted to an upright disposition. Following this maneuver, the mast may be either rotated up and out of the water to an erect disposition or, alternatively, the mast can be jacked vertically through the deck.

  • Patent number: 5843136
    Abstract: A method and apparatus for attenuating polarization voltages or "afterpotentials" which develop at the heart tissue/electrode interface following the delivery of a pacing stimulus to the heart tissue such that the evoked response of the heart may be accurately detected to determine whether each pacing stimulus resulted in heart capture or contraction, thereby facilitating improved tracking of the capture threshold for minimizing power consumption while assuring therapeutic efficacy. The conventional large capacitance coupling capacitor used to suppress DC components of the pacing spike has a second, much lower capacitance capacitor connector in series with it, the second capacitor being shunted by a switch so that its value can be selectively inserted in series with the coupling capacitor to effectively lower the overall capacitance of the coupling capacitor following delivery of the pacing spike.

  • Patent number: 5839623
    Abstract: Spray bottle dispensers for liquid products featuring, in the case of a first embodiment, a refillable and rechargeable container especially designed so that the product being dispensed does not come into contact with working parts of the valve structure, thus obviating problems due to gum-up. In an alternate embodiment, loss of the propellant (compressed air) through the container wall is prevented by using a first compliant walled container for the product to be dispensed and a second compliant wall container as a liner.
