20140202365 | COMBUSTION APPARATUS WITH DIRECT FIRING SYSTEM - The invention relates to a combustion apparatus, in particular to a burner for the combustion of carbonaceous fuel. The combustion apparatus comprises a burner having a burner inlet for receiving a supply of combustible pulverous fuel and a supply of comburant gas and a burner outlet in the vicinity of which combustion of the fuel is supported during use; at least a primary conduit defining a flow channel for conveying a mixture of fuel and comburant gas from the burner inlet to the burner outlet; a fuel feed line defining a flow channel which conveys a pulverous combustible fuel in a dense phase; and a supply conduit fluidly connecting a comburant gas supply to the primary conduit and defining with the primary conduit a primary flow stream; wherein the fuel feed line is provided with a fuel feed outlet into the supply conduit upstream of the burner inlet to supply pulverous combustible fuel in a dense phase; and wherein the primary flow stream is provided with a mixing device downstream of the fluid supply outlet. A method for combusting pulverous combustible fuel in a burner embodying such principles is also described. | 07-24-2014 |

20110271583 | Method and apparatus for extermination of pests - An extermination device for exterminating pests includes a holder, trigger mechanism and a resilient ring mounted on the holder. When a pest actuates the trigger mechanism, the ring is released from the holder onto the pest, thereby killing the pest in a humane manner. A cover may be provided to protect the trigger mechanism from dirt and animals larger than target pest size. A loading device having a tapering body adapted to allow a resilient ring to be expanded from the narrow end to the wide end of the tapering body, wherein the wide end includes a formation adapted to engage with a holder of an extermination device. | 11-10-2011 |

20110195519 | Thin-film photochemical vapour generation - A photochemical vapour generator is disclosed having a reaction chamber with a liquid sample inlet, a carrier gas inlet and a carrier gas outlet. A liquid sample support surface for supporting a film of a liquid sample is in the reaction chamber. A source of ultraviolet radiation is positioned in radiative contact with the liquid sample support surface. Also described is a process for detecting and/or quantifying an analyte by providing a liquid film of a sample containing an organic acid or a salt thereof and a precursor compound of the analyte, exposing the liquid film to ultraviolet radiation to generate a volatile species of the analyte, separating the volatile species from the liquid film to form a vapour containing the volatile species, and directing the vapour to a detector to detect and/or quantify the analyte in the vapour. Amalgamation of photochemical reactions with thin film generation and gas-liquid phase separation achieves the benefits of all of these principles in a single unit, providing a simple and effective way of enhancing generation of an expanded suite of elements. | 08-11-2011 |

20150144331 | Systems and Methods for Real-Time Evaluation of Coiled Tubing Matrix Acidizing - A matrix acidizing monitoring system wherein a sensor array is operably associated with a matrix acidizing bottom hole assembly and contains first and second sets of sensors that detect a matrix acidizing operational parameter at different times at one or more particular locations along the wellbore. This allows the effectiveness of the acidizing to be modeled. | 05-28-2015 |
