  • Electronic pest monitoring system and method
    Patent number: 6445301
    Abstract: An electronic pest monitoring system includes an electronic pest monitoring device which may be used in combination with or separate from a bait box. The electronic pest monitoring device is adapted to be removably attached to a bait box. The electronic pest monitoring device includes a pest detector, such as a passive IR detector, which provides a pest detection signal in response to the presence of a pest. A processor coupled to the pest detector includes a real-time clock, and stores in memory a time and date of occurrence of the pest detection signal and a duration of the presence of the pest. Such pest detection event information may be transmitted from the electronic pest monitoring device over a wireless communications channel, such as an IR communications channel, to a hand-held computer unit for display and analysis.

  • Lock-out valve with controlled restart
    Patent number: 4995421
    Abstract: A lock-out valve is designed to direct pressure fluid to an operational port and system, and to exhaust such pressure for purposes of repair or reconstruction of a valve controlled system. The valve may be quickly moved to the exhaust phase by a manual stroke overriding threads between two concentric parts. However, reverse motion of the valve to re-establish pressure to the operational port can only be accomplished by a turning action on the manual actuator. This insures a slow return of pressure to the system and a slow start up so that the controlled system can be safely and properly reset. The thread design is such that the motion in one direction will override the threads but prevent reverse action except by turning.

  • Method of controlling Corbicula
    Patent number: 4462914
    Abstract: A method of controlling Corbicula in aqueous systems comprising treating said systems with a cationic polymer. A preferred polymer is a poly (quaternary ammonium) compound having the recurring structure:[DMDAAX.sup..crclbar. ]where DMDAAX.sup..crclbar. is a polymer unit resulting from monomeric dimethyldiallylammonium X.sup..crclbar. ; and X.sup..crclbar. is an anion; said polymer preferably having a weight average molecular weight of from about 200,000 to 400,000.
