Patent number: 7010880Abstract: A fishing tool designed to attach and remove split shot to/from fishing line is disclosed. The tool comprises a top member, which is a flexible bowed strip of spring metal, pivotally connected to a base member, which is a rigid strip of sheet metal. Split shot is attached by threading line through the split and securing the shot in a splayed groove in the base member. Manual pressure applied to the plier end of the top member bends it down so as to compress the shot, causing it to close around the line. Split shot is removed from a line by placing the attached shot in a concave depression in the base member and exerting downward pressure on the prying end of the top member. A wedge-shaped prying tool in the prying end penetrates the split in the shot and pries it open, releasing the line.Type: GrantFiled: September 8, 2004Date of Patent: March 14, 2006Inventor: Steven H.

Patent number: 7010882Abstract: An electronic animal trap with a CPU-controlled, rearming, high voltage output circuit for trapping and exterminating pests. The high-voltage output circuit is connected to a pair of killing plates which are activated with a high-voltage pulse train for a period of time constituting a killing cycle when a known impedance is sensed across the plates. If, upon conclusion of the killing cycle, the impedance remains across the plates, the circuit activates a visual indicator to alert a user that the trap contains a dead mouse. However, if the impedance increases to that of an open circuit, likely meaning the animal has escaped, the circuit automatically rearms itself and no visual indicator is initiated.Type: GrantFiled: November 17, 2004Date of Patent: March 14, 2006Assignee: Woodstream CorporationInventors: Christopher T. Rich, Larry L Harman, David L. Anderson, Michael J. Gehret

Patent number: 7010920Abstract: A method for producing power to drive a load (17) using a working fluid circulating through a system that includes a prime mover (12) having an inlet and an accumulator (20) containing discharge fluid exiting the prime mover. A stream of heated vaporized fluid is supplied at relatively high pressure to the prime mover inlet and is expanded through the prime mover (12) to a lower pressure discharge side where discharge fluid enters an accumulator (20). The discharge fluid is vaporized by passing it through an expansion device (28) across a pressure differential to a lower pressure than the pressure at the prime mover discharge side. Latent heat of condensation in the discharge fluid being discharged from the prime mover is transferred by a heat exchanger (14) to discharge fluid that has passed through the expansion device (28).Type: GrantFiled: December 23, 2003Date of Patent: March 14, 2006Assignee: Terran Technologies, Inc.Inventors: Theodore Charles Saranchuk, Donald Edward Marksberry

Patent number: 7010922Abstract: According to the invention, there is provided a single shaft combined cycle power plant which can quickly switch from single operation of a gas turbine to combined operation of the gas turbine and a steam turbine, and can quickly increase output power, from low power to high power. The single shaft combined cycle power plant includes a means for maintaining the rotation speed of the steam turbine at a speed slower than but near a rated rotation speed when the steam turbine is separated from a coupled unit of a generator and the gas turbine.Type: GrantFiled: July 28, 2004Date of Patent: March 14, 2006Assignee: Hitachi, Ltd.Inventors: Hidekazu Takai, Ryouichi Ohkura

Patent number: 7010923Abstract: A method for operating a gas turbine engine facilitates reducing an amount of emissions from a combustor. The combustor includes a mixer assembly including a pilot mixer, a main mixer, and a centerbody that extends therebetween. The pilot mixer includes a pilot fuel nozzle and a plurality of axial swirlers. The main mixer includes a main swirler and a plurality of fuel injection ports. The method comprises injecting fuel into the combustor through the pilot mixer, such that the fuel is discharged downstream from the pilot mixer axial swirlers, and directing flow exiting the pilot mixer with a lip extending from the centerbody into a pilot flame zone downstream from said pilot mixer.Type: GrantFiled: August 30, 2004Date of Patent: March 14, 2006Assignee: General Electric CompanyInventors: Alfred A. Mancini, Michael L. Vermeersch, Duane D. Thomsen, Allen M. Danis, James N. Cooper, Steven J. Lohmueller, Hukam C. Mongia

Patent number: 7010924Abstract: A refrigerated display case reduces the temperature of refrigerated items in the front of the case and achieves a tighter temperature range within the case. Air drawn from a cooler is further cooled by a coil. Some of the cold air is discharged along the front of the case as an air curtain is and drawn by fans back into the cooler. The remaining cold air is directed to a duct in the rear of the case. Openings in the duct allow air to flow across the refrigerated items towards the front of the case, further reducing the temperature of the refrigerated items in the front of the case. To prevent refrigerated items in the rear of the case from freezing, air entering the duct is warmed with air that bypasses the coil.Type: GrantFiled: September 25, 2002Date of Patent: March 14, 2006Assignee: Carrier Commercial RefrigerationInventor: Michael J.

Patent number: 7010925Abstract: A method of detecting and diagnosing operating conditions for a heat pump water heating system includes the steps of monitoring system operating conditions and comparing actual operating conditions to predicted operating conditions. The predicted operating conditions are based on expected pressures and temperatures given current system inputs. A difference between the actual and expected values for refrigerant pressures and temperature outside a desired range provides indication of a fault in the system. The system controller initiates a prompt to alert of the need for maintenance and direct to potential causes.Type: GrantFiled: June 7, 2004Date of Patent: March 14, 2006Assignee: Carrier CorporationInventors: Tobias Sienel, Yu Chen, Bryan Eisenhower, Julio Concha, Young Kyu Park, Lili Zhang, Jeffrey Nieter, Nicolas Pondicq-Cassou

Patent number: 7010927Abstract: An air conditioning system includes a supplemental storage container that allows for transferring refrigerant into or out of an air conditioning or refrigeration system based upon different operating conditions. In one example, a controller controls the operation of valves that selectively couple the storage container to the high pressure side or the low pressure side of the system. Depending on operating conditions, when it is desirable to increase an amount of refrigerant in the system, refrigerant is transferred from the storage container to the low pressure side of the air conditioning or refrigeration system. Under conditions where the amount of refrigerant in the system is above a desired amount, refrigerant can be transferred from the high side of air conditioning system to the storage container to bring the pressure within the system closer to the desired level.Type: GrantFiled: November 7, 2003Date of Patent: March 14, 2006Assignee: Carrier CorporationInventors: Alexander Lifson, Michael F. Taras, Thomas J. Dobmeier

Patent number: 7010928Abstract: A clamp assembly for mounting devices such as a condensate over detection and/or prevention mechanism to a drain pan of an air cooling system includes first and second clamp members that are attachable to each other. The first clamp member includes a first engaging portion that engages a first surface of the drain pan, and the second clamp member includes a second engaging portion that engages a second surface of drain pan. The assembly includes a locking mechanism that locks the first and second clamp members to each other so that the pan is clamped between the first and second clamp members.Type: GrantFiled: December 30, 2003Date of Patent: March 14, 2006Inventor: Gerald S.
