Abstract: A sports equipment surface cleaning safety device is disclosed which serves the purpose of removal of materials, such as snow, ice or mud, from boot soles or other contacting surfaces of sports equipment through motions such as scraping or brushing. The device is intended to be integrated within, or mechanically mounted to a pole, such as a ski pole or trekking pole. It is constructed with materials such as plastics and/or metal, utilizing conventional methods of fabrication such as 3d printing, injection molding, gluing, casting, or machining.

Abstract: A method for printing a structure, the structure including a plurality of pillars. The method for printing can include ejecting only a first drop of a print material such as a liquid metal sequentially at each of a plurality of pillar locations, then ejecting only a second drop of the print material sequentially onto the first drop at each of the plurality of print locations. Additional drops can be ejected at two or more of the pillar locations to form the plurality of pillars. Ejecting only a first drop at each pillar location allows the first drop to cure (i.e., cool or dry) before ejecting the second drop. The printer continues printing while the drops cure, thus improving processing efficiency and increasing production throughput.

Abstract: A downhole motor-pump assembly disposed within a tubular string includes a rotor and a stator. The rotor has a first rotor portion and a second rotor portion. The first rotor portion has a first geometrical shape and the second rotor portion has a second geometrical shape. The first geometrical shape differs from the second geometrical shape. The stator has a first stator section and a second stator section. The first stator section is spaced from the second stator section by a gapped region. The first rotor portion is located within the first stator section and the second rotor potion is located within the second stator section. The differing geometry causes a difference in displacement in the first and second sections per revolution of the rotor. Therefore the difference in displacement must be made up and is induced into the tool at the gap or drillings between sections, and this additional volume is effectively pumped.

Abstract: Methods for preparing magnetic nanoparticles comprising metal, metal carbide, metal nitride, metal sulfide, metal phosphide, metal oxide or a mixture thereof are disclosed. Methods for preparing magnetic nanoparticles having a core comprising metal, metal carbide, metal nitride, metal sulfide, metal phosphide, or a mixture thereof and a metal oxide shell are also disclosed. The methods comprise the solution-phase decomposition of a precursor at elevated temperature then exposure of the reaction mixture to an oxidizing medium, such as air.

Abstract: The present invention provides a method for preparing nanoparticles of group IV elements, particularly nanoparticles of Si, Ge and Sn, and binary and ternary alloys of these elements. The method comprises the solution-phase decomposition of one or more group IV metal precursors at elevated temperature and under an inert atmosphere at atmospheric pressure, using a decomposition-promoting reagent. A surface-bonding agent is added to the reaction mixture to form an organic layer surrounding the nanoparticles and prevent aggregation.

Abstract: A method for distributing a document by email. The method includes scanning a business document, extracting an email address from the business document, scanning a document and automatically emailing the scanned document to the email address extracted from the business document.

Abstract: A relatively compact portable tong assembly utilizing adaptable jaws for gripping the threaded box and pin ends of adjacent pipe joints without the use of an external support and thus applying final make-up torque or applying initial breakout torque to threaded pipe joints using only a spanner, socket and ratchet or other such hand tools for quickly applying torque to at least one of the tong jaws. An integral means is also provided for accurately measuring the amount of torque being applied to the joints.

Abstract: A switch and method are provided for turning on and off an electrical device. The switch includes a control module, having a time module and an electrical output to which an electrical device can be connected. The time module includes a clock which is programmable to disconnect power to the electrical device at a set-off time. A light sensor is operatively associated with the control module and transmits a light signal to the control module based on light level. The control module is adapted to provide power to the electrical output when the light module indicates that the light level is below a threshold level and the time is before the set-off time thereby providing power to an electrical device connected to the electrical output.
