  • Publication number: 20180216747
    Abstract: A multifunctional restrictive valve for controlling the flow of water therethrough. The valve has a main body with a flow channel through the main body. The main body receives water upstream thereof through an inlet port and passes it out through an outlet port at the downstream end of the body. A flow control assembly is located in the flow channel and includes a temperature sensor/actuator acting on a piston to move, when the temperature sensor heats up the piston, to block water flow control ports. The flow control assembly also includes an override feature wherein the piston is located within a slide and the flow control ports are located in the slide. By moving the slide away from the piston when the piston is blocking the flow control ports, the temperature sensor and piston may be overridden and flow may resume through the main body.

  • Publication number: 20170340797
    Abstract: Doxorubicin is extracted from blood using anionic material, such as a resin comprising sulfonated polystyrene divinylbenzene beads, and polyethersulfone membrane, or both. After exposing the resin and/or membrane to blood in order to remove doxorubicin therefrom, the doxorubicin maybe extracted from the resin and/or membrane by exposing the material to an extraction solution, sonicating the extraction solution to enhance release of the doxorubicin, and repeating the exposure and sonication in order to remove substantially all of doxorubicin from the resin.

  • Publication number: 20130344746
    Abstract: A system and method for connecting a number of network devices together in a daisy chain configuration is disclosed. A connector device comprising a number of cable interfaces for a cable is used to allow a number of network devices connected to a network to be connected in a free-form manner, yet still maintain a daisy chain configuration. A cable comprising at least two conductors, wherein the conductors are preferably a twisted pair of copper wire, is used to connect the network devices, so that each network device only has a single cable connected to it. Additional network devices can be added to the network by simply connecting the additional network device into the existing network with the use of an additional cable and an additional connector device. Wherever the additional network device is added to the existing network, the network will be maintained in a daisy chain configuration.

  • Patent number: 8588222
    Abstract: A network device configured to allow the connection of the network device to a network in a daisy chain configuration using a single cable. The network device is connected to a cable with two conductors by a socket that is adapted to receive a plug connected to the end of the cable. When the plug on the end of a cable is inserted into the socket, a first conductor in the cable is connected to an input port of a network component and a second conductor of the cable is connected to an output port of a network component. A signal from the network is transmitted down a first conductor in a cable to a network device and the signal is then transmitted back from the network device down a second conductor in the same cable.

  • Patent number: 8464962
    Abstract: A temperature control valve that effectively manages fluid pressure therethrough, including pressure differentials which may exist therein, such as from the upstream port to the downstream port, and about a piston slidingly disposed therewithin proximate a fluid flow path. In one embodiment a 3 stage valve is provided whereby fluid flows therethrough when the piston is in a first position, fluid flow is inhibited in a second piston position, and an override third position whereby fluid flows therethrough. When the piston is in the second position, the fluid pressure differential across the piston is balanced and an axial spring force on the piston is relatively small, thereby reducing any subsequent axial force required to advance the piston to the third free flow position, and allowing the valve to be comprised of cheaper materials including plastic.
