Abstract: A first plurality of wireless devices each having a microphone and a wireless antenna forming a first plurality of microphones and a first plurality of wireless antennas may be provided. The first plurality of wireless devices may be configured to transmit the first plurality of signals over Bluetooth. A master transceiver with a first microphone and a first wireless antenna may also be provided and the master transceiver can be configured to receive the plurality of signals from the plurality of wireless devices over Bluetooth. The master transceiver can be configured to combine the plurality of signals and the master signal into a combined signal. And the master transceiver can be configured to broadcast the combined signal over Bluetooth and Wi-Fi simultaneously with the transmission over Bluetooth for redundancy.

Abstract: A method and apparatus for treating the production tubing string of a flowing gas well is disclosed. The method includes introducing treatment fluid into the wellhead end of the production tubing string, allowing an applicator fall through the production tubing string thus applying a first coating of treatment fluid and retracting the applicator thus applying a second coating of the treatment fluid.

Abstract: A method for cleaning and treating the walls of a kettle containing a molten metal such as zinc comprises injecting nitrogen or other gas into the molten metal through a reaction container. The reaction container may contain a second metal capable of forming an alloy with the molten metal. The reaction container is immersed in the molten metal adjacent the sidewall of the kettle and is moved around the peripheral edge of the kettle to disperse the second metal and the nitrogen into molten metal. The reaction container includes a gas feed pipe having a lower end with a plurality of gas outlets. An enclosure for containing the second metal surrounds the lower end of the feed pipe such that gas exiting the feed pipe bubbles upwardly through the enclosure to contact the second metal. In a preferred embodiment, the gas is nitrogen and the second metal is aluminum which form aluminum nitride in the molten metal.

Abstract: An arrow release mechanism having opposed pivotal jaws with substantially hemispherical sockets on facing sides for releasable reception of a substantially spherical arrow nock. One embodiment includes a pivotal trigger for locking and unlocking the jaws in their nock grasping position and a universally coupled handle. A second embodiment includes two linkage members for locking and unlocking the jaws.

Abstract: An arrow release mechanism formed of only eight separate parts, such mechanism including a handle, a pair of opposed jaws pivotally coupled to the handle, and a trigger, pivotally coupled to the jaws, for releasing a locking assembly to thereby release a substantially spherical arrow nock grasped in substantially hemispherical sockets in the jaws. The pivotal coupling of the jaws and the handle together with the reception of the substantially spherical nock in the substantially hemispherical sockets provides a universal coupling between the arrow and the handle so that relative movement therebetween during aiming of the arrow will not mar the accuracy of the aiming.
