Abstract: A drill pipe mountable wellbore cleaning tool apparatus is of an improved configuration that enables attachment to a drill pipe joint having first and second connector end portions and a cylindrically shaped portion in between the connector end portions. The drill pipe joint with attached debris cleaning tool or tools is made part of a drill string. The apparatus includes a support sleeve that is mounted to the drill pipe joint in between the connector end portions. The support sleeve abuts but does not invade the integrity of the cylindrical portion. Centralizers are attached to the opposing ends of the support sleeve, with each centralizer overlapping a portion of the support sleeve. The support sleeve carries one or more debris cleaning tools in between the centralizers. These tools enable debris to be removed from a wellbore.

Abstract: Methods and systems are provided for independent audio volume control. An example audio system may include a hearing device operable to adaptively control a first signal, according to a setting, to provide an audio output. The hearing device may be operable to generate a new value of the setting according to an input that is received at a particular time, and adjust the setting from an old value to the new value according to a delay with respect to the particular time. The adaptive controlling may include one or both of mixing of the first signal with a second signal and applying a volume adjustment of the audio output according to the setting. The second signal may include audio generated via a game console and/or via a smartphone.

Abstract: A new process for the decomposition of hydrocarbon feed stream(s) that achieves the conversion of a hydrocarbon feed stream to hydrogen and filamentous carbon, with minimal resulting production of carbon oxides is described herein. In this invention it is proposed to achieve the hydrocarbon conversion by the use of dual fluidized bed reaction zones, fluidly connected, for (i). hydrocarbon reaction (the reactor) and (ii). catalyst regeneration and heating (the regenerator) and to use a transition metal supported catalyst to achieve high hydrocarbon conversion and to produce high quality filamentous carbon.
