  • Patent number: 6447674
    Abstract: A gravity flow sludge load-out system for rapid and accurate loading-out of large volumes of treated biosolids from a wastewater dewatering plant, said system includes a plurality of hoppers 12, 14 supported by a main structure 16 having a plurality of vertical support members 20, each resting on a load cell 28, a sludge inlet at the tip of each hopper, and hydraulically controlled metering gates 40 at the bottom. A PLC 70 controls delivery of sludge from a dewatering facility, including e.g. a dewatering centrifuge 56, into the hoppers and then controls load-out of the sludge to a container truck by providing real-time monitoring of net sludge load-out and tight control of metering gates.

  • Patent number: 5891693
    Abstract: The present invention relates to vectors useful for transforming a lymphoid cell line to glutamine independence. The vectors comprise an active glutamine synthetase (GS) gene as well as a heterologous gene of interest to be expressed. The preferred embodiments encompass vectors wherein the heterologous gene is expressed from a relatively strong promoter and the GS gene is expressed from a relatively weak promoter. In one example, the heterologous gene is operatively linked to the hCMV-MIE promoter and the GS gene is operatively linked to the SV40 early region promoter.

  • Patent number: 5335748
    Abstract: A vehicular anti-theft apparatus uses the unbuckling of a seatbelt to produce a surreptitious signal that activates a timing circuit which disables the motor after a preselected period of time. When the seatbelt is unfastened, an electrical signal is generated by a sensor switch within the seatbelt buckle and sent to the timing circuit. This circuit activates a solenoid after the preselected time has elapsed. Activation of the solenoid opens the ignition circuit, which makes the vehicle stall. In order for the motor to be restarted, the timing circuit must be reset using a circuit control keypad. The circuit control keypad is a separate and portable hand-held push-button device that allows an authorized operator manually to enter a secret code. The circuit control keypad plugs into a hidden port, thereby electrically interfacing with the timing circuit.

  • Patent number: 5122464
    Abstract: Recombinant DNA sequences which encode the complete amino acid sequence of a glutamine synthetase, vectors containing such sequences, and methods for their use, in particular as dominant selectable markers, for use in co-amplificiation of non-selected genes and in transforming host cell lines to glutamine independence.
