  • SELF-LOCKING FLUID CONNECTION
    Publication number: 20090299337
    Abstract: A self locking luer type connection. The luer lock includes a male and female luer portion adapted to removably connect to each other and capable of forming a sealed fluid flow path. A combination of both hard and semi-hard materials is utilized for either a male luer portion or a female luer portion to create a sealing surface that features the benefits of both materials. By applying a less rigid material to a rigid base, the luer lock connection is able to be used multiple times, have a large range of tightening positions that function to create a seal, will be reliable in high-pressure connections, and will function with multiple types of the corresponding luer portion.

  • Bypass circuit to prevent arcing in a switching device
    Patent number: 7342754
    Abstract: A device is provided for preventing arcing between contacts of a switching device as the contacts of the switching device are opened. The device includes a coil suppression circuit connected in parallel with the coil. The coil suppression circuit dissipates the energy stored in the coil in response to the de-energization of the coil. A first solid state switch has a gate operatively connected to the coil suppression circuit and is connected in parallel with the contacts. The first solid state switch is movable between an open position preventing the flow of current therethrough and a closed position in response to the dissipation of energy by the coil suppression circuit.
