The bag has an opening around its first end, and another at the second end. The opening at the first end is generally circular, with a drawstring to facilitate attachment around the discharge tube and hood of the mower. A cleat in proximity to the opening allows for securing the drawstring. The opening at the second end is likewise secured by a drawstring and cleat combination, or by a hook-and-loop fastener. A mesh area in the surface of the bag relieves the pressure within the bag caused by the entry of air forced up the discharge tube by the action of the cutter blades of the mower.Type: GrantFiled: November 24, 2000Date of Patent: April 15, 2003Inventor: Damon H.

Patent number: 6546711Abstract: A sewing yarn comprises at least two roving yarns, which are twisted together with one another, whereby each roving yarn has the structure of a core yarn, comprising at least one first multifilament yarn component, forming a yarn core, and a second fiber yarn component spun over the core. In the cross-section of the sewing yarn, the fiber yarn thread covering of at least one roving yarn contains less than 41 individual fibers. For the manufacture of each roving yarn, a slubbing made of fiber yarns is compacted to 10 to 25 times of the volume of the roving yarns, introduced into a spinning device with the multifilament yarn component serving as the core, and is spun in said device, with at least two roving yarns being thereafter twisted together with one another.Type: GrantFiled: April 30, 2002Date of Patent: April 15, 2003Assignee: Amann & Soehne GmbH & Co.Inventors: Karl Greifeneder, Kurt Truckenmueller

Patent number: 6546712Abstract: A method, apparatus and system for improving reverse oscillating lay (ROL) consistency during an optical cable manufacturing process. A torque capstan receives an optical fiber cable from an ROL machine that places reverse-oscillating lay on the core of an optical cable, but also generates some undesirable fluctuating back-tension in a direction opposite a direction in which the optical fiber cable is being pulled during manufacturing of the optical cable. The optical cable comprises a plurality of subunit cables. A drive system coupled to the torque capstan is controlled by a control system in such a way that the torque capstan applies a certain amount of force to the optical cable in a direction substantially parallel to the direction in which the optical cable is being pulled during manufacturing.Type: GrantFiled: April 12, 2001Date of Patent: April 15, 2003Assignee: Fitel USA CorporationInventors: Parry A. Moss, Wayne M. Newton, Eugene R. Rusiecki, Mark I. Shmukler, Carla G. Wilson

Patent number: 6546713Abstract: A gas turbine for power generation operated at a turbine nozzle inlet temperature ranging from 1200 to 1650° C., which is improved to obtain a high heat efficiency by making disk blades and nozzles arranged in first to final stages from optimum materials and optimally cooling these disk blades and nozzles, and to obtain a combined power generation system using the gas turbine. The combined power generation system includes a highly efficient gas turbine operated at a turbine nozzle inlet combustion gas temperature ranging from 1200 to 1650° C., and a high pressure-intermediate pressure-low pressure integral type steam turbine operated at a steam inlet temperature of 530° C. or more, wherein the gas turbine is configured such that turbine blades, nozzles and disks are each cooled, and the blades and nozzles are each made from an Ni-based alloy having a single crystal or columnar crystal structure and disks are made from a martensite steel.Type: GrantFiled: June 8, 2000Date of Patent: April 15, 2003Assignee: Hitachi, Ltd.Inventors: Kishio Hidaka, Shigeyoshi Nakamura, Yutaka Fukui, Masao Shiga, Ryo Hiraga, Hajime Toriya, Toshio Fujita

Patent number: 6546714Abstract: A reduced toxicity fuel satellite propulsion system including a reduced toxicity propellant supply (10) for consumption in an axial class thruster (14) and an ACS class thruster (16). The system includes suitable valves and conduits (22) for supplying the reduced toxicity propellant to the ACS decomposing element (26) of an ACS thruster. The ACS decomposing element is operative to decompose the reduced toxicity propellant into hot propulsive gases. In addition the system includes suitable valves and conduits (18) for supplying the reduced toxicity propellant to an axial decomposing element (24) of the axial thruster. The axial decomposing element is operative to decompose the reduced toxicity propellant into hot gases. The system further includes suitable valves and conduits (20) for supplying a second propellant (12) to a combustion chamber (28) of the axial thruster, whereby the hot gases and the second propellant auto-ignite and begin the combustion process for producing thrust.Type: GrantFiled: April 17, 2001Date of Patent: April 15, 2003Assignee: The United States of America, as represented by the Administrator of the National Aeronautics and Space AdministrationInventor: Steven J. Schneider

Patent number: 6546715Abstract: A thrust reverser for a turbofan engine having an air duct defined radially inwardly by a cowl around a gas turbine and radially outwardly in part by a fan case of the engine includes a bulkhead that is adapted to be mounted on the fan case. A translating sleeve is supported for movement axially between a closed position adjacent the bulkhead and an open position spaced apart axially to the rear of the bulkhead so as to form a outlet opening for discharge of air from the air duct. A cascade array fixed in the outlet opening has a substantially conical portion, the forward end of which is of a diameter substantially smaller than the diameter of the rearward end.Type: GrantFiled: January 25, 2001Date of Patent: April 15, 2003Assignee: Rohr, Inc.Inventors: Robert D. Blevins, Michael R. Aten, Jihad I. Ramlaoui

Patent number: 6546716Abstract: A variable area exhaust nozzle with a variable thrust vector angle for a turbo-fan engine and mounted on the aft portion of the nacelle which wraps said engine. The nozzle may include a fixed structure having at least two lateral arms separating two radial cutouts. The cutouts are positioned one above the other, one being located above the engine axis, the other one below the engine axis. At least two shells close the fixed structure cutouts and are pivotally mounted on the fixed structure to form a portion of the exhaust nozzle of the engine. A sealing means ensures fluid tightness between the shells and the fixed structure for any angular position of said shells. Actuator means are provided for pivoting the shells either to a symmetrical configuration for changing of the value of the exhaust area of the nozzle or to an unsymmetrical configuration for changing the angle of the thrust vector of the exhaust nozzle.Type: GrantFiled: April 26, 2001Date of Patent: April 15, 2003Inventor: Jean-Pierre Lair

Patent number: 6546717Abstract: In the control of pollutants such as NOx in the exhaust gases from internal combustion engines, ozone is reacted with NO to form NO2, which is then reduced catalytically to N2, by reacting NO2 with ammonia. The NO2 produced can react with the particulates of Diesel engine to exhaust gas to regenerate a particulate filter.Type: GrantFiled: October 2, 2000Date of Patent: April 15, 2003Assignee: Johnson Matthey Public Limited CompanyInventors: Guy Richard Chandler, Alan Francis Diwell, Raj Rao Rajaram
