  • Immunoassay for tetrachloroisophthalonitrile (chlorothalonil), its derivatives and breakdown products
    Patent number: 5654178
    Abstract: Novel derivatives of chlorothalanil.RTM. (tetrachloroisophthalonitrile, TCPN), permit conjugation of the TCPN derivative to a carrier useful as an immunogen to induce antibodies specific for TCPN or a TCPN metabolite, or a screening antigen to detect such antibodies. Polyclonal and monoclonal antibodies specific for TCPN or a TCPN metabolite, as well as hybridoma cells producing such antibodies are disclosed. Also provided are immunoassay methods for detection and quantitation of pesticide chemicals, in particular, the fungicide TCPN or a TCPN metabolite, and kits containing a TCPN derivative screening antigen, an anti-TCPN or anti-TCPN metabolite antibody useful for performing the immunoassays.

  • Tank having an inner bladder
    Patent number: 5613622
    Abstract: A container for containing flowable material comprises a rigid tank having a top opening therein for filling the tank with flowable material. A bottom opening in the lowermost portion of the tank for evacuating the flowable material. A cap seals the top opening in the tank and a piping assembly is connected to the bottom opening. A collapsible bladder inside the tank prevents the flowable material from coming into contact with the tank. A mating top cover and bottom base assembly are shaped to receive and enclose the tank. The piping assembly includes a dispensing spout which utilizes a spout, a dry-lock or a spring valve.
