  • Publication number: 20060124532
    Abstract: A cartridge based water purification and filtration system which permits cartridge changes without drainage at the input and output ports. Interlocking flanges at the manifold and cartridge lock the cartridge to the manifold and raised surfaces at the cartridge operate the inlet valve with a rotational seating of the cartridge. A spring biased inlet valve depends from a supply manifold input port and cooperates with the filter cartridge to prevent forward flow until the cartridge is seated to the manifold. The check valve includes a split stem which prevents chatter with valve operation. A check valve at the output port cooperates with a sealed bayonet fitting that mates to a concentric outlet port at the cartridge to prevent back flow with cartridge removal.

  • Patent number: 6973223
    Abstract: In a device (100) for continuously varying the extinction ratio, ER, a laser diode (102) is connected to a first end of a PZ fiber (108). At a second end, the PZ fiber is connected to a connector (110). At the other end of the connector a PM fiber (106) is connected. The two fibers meet in the connector, which means that opposite end facets of the fibers are located at a very close distance of each other. A rotation is produced by a rotator (104), mechanically coupled to the connector. The device can be used for: selecting a desired ER of the PM fiber; achieving high accuracy of angular alignment between the principal axes of two PM fibers (106, 506); evaluating the quality of angular alignment of a splice between two PM fibers made by a splicer; and setting the adjustment/calibration of a PM fiber.

  • Publication number: 20040079071
    Abstract: A gas turbine has a fuel injection system for supplying pressurized fuel gas to a combustion chamber of a gas turbine. The fuel injection system has at least one electrically controllable magnetic valve working with pulse-width modulation, i.e., controlling the gas flow by varying the length of its opening time pulses in relation to its closing time, in a gas supply conduit. The fuel injection system has at least one electrically controllable magnetic main valve arranged in the supply conduit. Moreover, at least one pilot valve is connected to the supply conduit with its upstream end after the main valve and with its downstream end connected to a conduit leading into a pilot flame chamber inside the combustion chamber.

  • Patent number: 6390095
    Abstract: A penile constriction collar that provides a relatively constant constriction pressure to a penis between flaccid and tumescent conditions. The collar is molded from medical grade silicone rubber having a durometer of 40-50 (±5) on the Shore “A” scale and exhibits a constriction force of 1.5 Kg (±0.5 Kg) over a range of changing diameter equal to or greater than 150%. One preferred collar exhibits a torroid or O'ring shape. Collars constructed with multiple regions of differing durometer and/or selected cross section shapes, and color can also be constructed to assure user comfort in erect and flaccid states.

  • Patent number: 6273009
    Abstract: A method for automatized combustion of solid fuel in a combustion apparatus which comprises a burner with a device, which is rotatable about the center axis of the burner for stirring the fuel in the burner which is connected to a boiler and has a feeding-in opening for fuel in the rear end of the burner outside of the boiler and an outlet opening for completely or partly combusted flue gases in the front end of the burner which opens in a combustion chamber inside the boiler which comprises a convection unit, from which a hot water conduit extends, the combustion apparatus also including a fan provided to be driven by a second motor for blowing combustion air into the burner, and a fuel charge feeder for fuel provided to be driven by a third motor.

  • Patent number: 6203315
    Abstract: A device for the combustion of solid fuel in the form of granules, pellets, chips or other fragmented or finely divided form, comprising a rotary reactor drum (1), which forms the main combustion chamber (13) and has a rear end wall (65) and at the opposite end an outlet (3) for combustion gases to a boiler part for heat transfer to water-cooled surfaces, for example, or other heat-absorbing means, an inlet (55) for combustion air to the main combustion chamber (13), means (40) for feeding fuel through the rear end wall (65) of the reactor drum and means for rotating the reactor drum around its center axis (2). Inside the main combustion chamber (13), in its rear part, is an inner, smaller drum (60), which is coaxial with the reactor drum (1) and has a perforated jacket. At least the bulk of the fuel is disposed to be fed into the inner, smaller drum (60) and from this to the surrounding main combustion chamber (13).

  • Patent number: 6164220
    Abstract: A device for combustion of granular material, for example wood flour pellets, chippings and the like, comprises a rotary solid fuel burner (1), air intake to the bumer, at least one conduit (18) for the supply of fuel and outlet (3) for combustion gases to a boiler part for heat transfer to water-cooled surfaces, for example. The rotary solid fuel burner is formed as a vessel with a rear wall, said outlet (3) for combustion gases and a jacket part between the rear wall and the outlet. A fuel feed pipe (18), which forms part of a fuel feed conduit, extends through the rear end wall, and an air admission pipe (19) surrounds the central fuel feed pipe at a distance from this, so that a space (20) which is ring-shaped in section is formed between the central fuel feed pipe (18) and the air admission pipe (19).
