  • Patent number: 8348100
    Abstract: A device and a method for delivering a fluid, in particular hot-melt adhesive. The device includes a base member having an inlet opening for receiving the fluid from a fluid source and an outlet opening for delivering the fluid to a nozzle arrangement. The nozzle arrangement has a discharge passage with a discharge opening for delivery of the fluid. A heat transfer member heats or cools the fluid and includes a heat transfer passage through which the fluid can flow. The heat transfer passage is of a flow cross-section which changes in the flow direction.

  • Patent number: 8346160
    Abstract: A signal repeating system for a wireless network includes an antenna configured for transceiving signals between a base station and a user equipment device. Repeating circuitry is coupled to the antenna and defines an uplink path for signals from the user equipment device to the base station and a downlink path for signals from the base station to the user equipment device. The repeating circuitry includes gain circuitry and gain control circuitry that is coupled to the gain circuitry. The gain control circuitry is operable for varying the gain of the repeating circuitry according to a waveform. Measurement circuitry measures the receive power in the uplink path over time from the user equipment device. Processing circuitry cross-correlates the inverted gain variation waveform with the measured receive power for determining the existence of traffic from user equipment devices in the uplink path.

  • Patent number: 8342058
    Abstract: A torsional vibration damper includes an inertia mass and a rotating shaft or hub with an elastomeric ring between the inertia mass and the rotating shaft or hub. A large portion of said elastomeric member is located in a channel located either in the inertia mass or in the hub. This allows one to achieve high contact pressure without creating a significant fatigue on the elastomeric member. This can be used with either a crankshaft damper or an internal or external drive shaft damper.

  • Patent number: 8337737
    Abstract: A dispenser for dispensing a liquid onto a substrate includes a dispenser body having an output and a reservoir in fluid communication with the output, the reservoir being defined by a wall and adapted to hold a supply of liquid to be dispensed. A piston is disposed in the reservoir and adapted to pressurize the liquid so that an amount of liquid is dispensed from the output of the dispenser. The piston includes a base portion having an outer periphery and having a first hardness, and a skirt portion integrally molded to the outer periphery of the base portion and having a second hardness lower than the first hardness. A two-shot molding operation may be used to form the piston with the base portion being, for example, formed in the first shot of the molding operation and the skirt portion being formed in the second shot of the molding operation.

  • Patent number: 8333686
    Abstract: An insertion device for inserting a cannula through tissue generally comprises an inner shaft, a tip member coupled to a distal end portion of the inner shaft, a hollow outer shaft slidably received over the inner shaft, and a compressible member received over the inner shaft between the tip member and the outer shaft. The compressible member is configured to be received in a lumen of the cannula, and the inner shaft is movable relative to the outer shaft along an axial direction to compress the compressible member between the tip member and the outer shaft so that the compressible member expands in a generally radially outward direction. The radial expansion of the compressible member releasably secures the insertion device to the cannula.
