  • Patent number: 9245465
    Abstract: An extended school stop sign, which may but need not be retrofitable, and barrier is mounted on a conventional school bus stop sign and extends further into the adjacent lane to reduce instances in which motorists pass a stopped school bus. A first frame is permanently secured to conventional stop sign mechanism. A second breakaway frame or arm is attachable to and detachable from the first frame, and extends beyond the conventional stop sign. If a vehicle strikes the second frame, it separates without significantly damaging the conventional stop sign mechanism. The extension arm can be moved between a retracted and extended position by the same mechanism that opens and closes the conventional stop sign, or with a new mechanism entirely.

  • Patent number: 8956340
    Abstract: A urethral catheter assembly utilizing a removable guide wire for navigating the catheter through a patient's urethral lumen during the insertion procedure. The guide wire being very flexible and having a low coefficient of friction, thus reducing the likelihood of injuring or puncturing the urethra during insertion. The guide wire extends beyond the distal end of the catheter assembly to ensure that the flexible tip of the guide wire is the first contact point between the catheter assembly and the urethral lumen. In one embodiment, the guide wire extends beyond the proximal end of the catheter assembly and is adapted to be handled by a medical doctor to manually maneuver the guide wire through the urethra.

  • Patent number: 8234864
    Abstract: An engine system is disclosed. The engine system includes an engine, an intake system for providing intake air to the engine and an exhaust system receiving exhaust gas from the engine. The engine system also includes a first exhaust turbine arranged downstream of the engine and a second and third exhaust turbines coupled in parallel and arranged downstream of the first exhaust turbine. A first valve is associated with the second and third exhaust turbines, the first valve configured to at least partially restrict exhaust gas to one of the second and third exhaust turbines and increase exhaust gas to the other turbine. The engine system also includes an exhaust gas recirculation system configured to redirect at least a portion of exhaust gas from the exhaust system to the intake system.

  • Patent number: 7591131
    Abstract: An exhaust treatment system for an engine is disclosed and may have an air induction circuit, an exhaust circuit, and an exhaust recirculation circuit. The air induction circuit may be configured to direct air into the engine. The exhaust circuit may be configured to direct exhaust from the engine and include a turbine driven by the exhaust, a particulate filter disposed in series with and downstream of the turbine, and a catalytic device disposed in series with and downstream of the particulate filter. The exhaust recirculation circuit may be configured to selectively redirect at least some of the exhaust from between the particulate filter and the catalytic device to the air induction circuit. The catalytic device is selected to create backpressure within the exhaust circuit sufficient to ensure that, under normal engine operating conditions above low idle, exhaust can flow into the air induction circuit without throttling of the air.

  • Publication number: 20070184205
    Abstract: A method of producing paperboard and cartons made therefrom is described incorporating a waterproof or water resistant coating applied to the interior of the carton except for areas intended for gluing. A coating material is applied to the surface of an applicator roll, and a portion of the coating material is then removed from the roll. Contact between a paperboard web and the roll transfers coating material to the web, creating a coated surface except for an uncoated stripe. A carton may be formed from the coated web with the uncoated portion of the carton cut from the uncoated strip.

  • Publication number: 20060120934
    Abstract: In a method to decrease emission of mercury, a factor is selected to control a combustion process to generate a flue gas comprising fly ash with enhanced unburned carbon; the combustion process is controlled according to a factor selected from reburning fuel, flue gas temperature, OFA injection, coal particle size, LNB flow, LNB design, combustion zone air, stoichiometric ratio of fuel, fuel/air mixing in a primary combustion zone and fuel/air mixing in a secondary combustion zone to produce the flue gas comprising fly ash with enhanced unburned carbon and to vaporize mercury; and the flue gas is allowed to cool to collect fly ash with enhanced unburned carbon with absorbed mercury. A system to decrease emission of mercury; comprises a combustion zone that is controlled to generate a flue gas comprising fly ash with enhanced unburned carbon and that produces vaporized mercury; and a post combustion zone to cool the flue gas to collect fly ash with enhanced unburned carbon with absorbed mercury.

  • Publication number: 20050260761
    Abstract: A method for monitoring and/or controlling performance of a selective catalytic reduction (SCR) emission control system includes injecting a quantity of a pollution neutralizing gas into a combustion gas stream containing a pollutant gas. The method also includes passing the stream over a catalyst bed to facilitate a reaction of the pollution neutralizing gas with the pollutant gas to produce an effluent and measuring a ratio of the pollution neutralizing gas to the pollutant gas in the effluent.
