  • Publication number: 20050040946
    Abstract: A remote controlled tree stand or hunting blind locating device which utilizes an LED having a substantially 360° light output which may be remotely activated by a user activated control device. The LED may be selectively activated in either a continuous or flashing mode by the paired activator. Due to the fact that the LED provides a 360° view angle, the functionality of the device is not dependent upon a user approaching from a particular angle.

  • Publication number: 20020192219
    Abstract: DAN (Differential-screening-selected gene Aberrative in Neuroblastoma) and gremlin proteins and related nucleic acids are provided. Included are natural DAN and gremlin homologs from several species and proteins comprising a DAN or gremlin domain having specific activity, particularly the ability to antagonize a bone morphogenic protein. The proteins may be produced recombinantly from transformed host cells with the subject nucleic acids. Also provided are isolated hybridization probes and primers capable of specifically hybridizing with the disclosed genes, specific binding agents and methods of making and using the subject compositions.

  • Patent number: 5408988
    Abstract: A soldering tool has a tip including a dispersing cylinder contained therein to disperse a gas stream and has a plurality of cooling fins at two sides of intermediate tubes. A hollow mixing tube has a needle hole disk surrounded by a plurality of air orifices to communicate with the inside, and a rotatable knurled knob for adjusting gas flow. A circular valve seal, made of elastic material has a radial shallow slot and a hollow valve seat body that is connected to a gas tank via a flexible tube.

  • Patent number: 5007405
    Abstract: A soldering tool comprises a cylindrical gas tank 10 which stores fuel gas and also encloses the greatest part of a switching and pressure regulating device. This device is composed of a rear barrel assembly 20 which contains a gas intake rod 25, a needle valve 311, gas filters, sealing or stopping rings and a gas inlet hole 314 through the valve stem wall, sealing or stopping rings, and a front barrel assembly 40 which is connected to the rear barrel assembly with a connector 42 provided with a further filter and a nozzle 426. Air inlet hole 314 provided in the side wall of the front barrel lets air mix with the gas flow just passing through the nozzle. The mixed fuel stream passes through a cooling fin assembly 50 and reaches the tool head which may have a catalytic heated soldering tip or a hot knife, or a torch. Through successive filtering, stopping, expanding and mixing, the fuel-air mixture of clean and well controlled pressure provides a desired quality and quantity for use with water.

  • Patent number: 4858593
    Abstract: The invention provides a portable soldering tool which eliminates the drawbacks such as unsteady heating and high fuel consumption of the conventional tools known heretofore. Essentially the soldering tool comprises a housing serving as a handle, wherein a gas tank, a gas duct with flow regulating means are housed. A tip assembly having a catalytic combustion element wrapped as the heating medium is connected to the front end of the housing, to be heated by the gas after it is mixed with air. An air-gas mixing chamber is provided at the end of the duct where the tip assembly is connected, the chamber being dome shaped and the flow regulator having dual assemblies including a needle valve and a nozzle both implemented with devices to retard the flow.
