Abstract: The present technology provides systems and methods for treating a fluid by contacting a compound to the fluid. The compound comprises an azodicarbonamide or an azodicarbonamide derivative, wherein the treatment reduces the amount of hydrogen sulphide, iron sulphide and/or mercaptan in the fluid. Certain embodiments of the present technology provide a composition comprising an azodicarbonamide or an azodicarbonamide derivative and a support and/or a suspension agent.

Abstract: The present technology relates to a method of treating hydrocarbon compositions such as crude oils to reduce or prevent naphthenate soap problems in upstream and downstream processes. It also relates to compositions for this use, for example.

Abstract: Locations of IC tags affixed to items are automatically recognized without requiring interrogators or antennas are allocated at respective inventory locations. To attain this object, interrogator 1 firstly transmits a unique ID readout command specifying read range, and corresponding IC tags 2a, 2b, 2c sequentially reply their unique IDs (Xa), (Xb), (Xc) respectively. At the same time, interrogator 1 transmits a probe signal send out command specifying ID, and corresponding IC tags 2a, 2b, 2c sequentially send out probe signals respectively. IC tag 2 that detects a probe signal with reception strength more than a predetermined level stores in its memory IDs (Xa), (Xb), (Xc) that interrogator 1 specified as adjacent ID. Then, interrogator 1 transmits an adjacent ID readout command specifying ID, and corresponding IC tags 2a, 2b, 2c sequentially reply adjacent IDs (Xb), (Xa.Xc), (Xb) stored in their memory respectively.

Abstract: The present invention is directed to a mousetrap comprising: an enclosure comprised of a top, a base and apertures located on each of the top and the base, wherein the enclosure is in an open position upon substantial alignment of the apertures; and a trigger mechanism comprising a lever arrangement and a biasing means operably connected to the top and the base, wherein the lever arrangement defines a gap through which a mouse is able to move through and as a result, raise the lever, wherein the enclosure, when in the open position, is able to admit the mouse into the enclosure and when in the closed position, the trapped mouse is substantially concealed within the enclosure, the mousetrap being set to trap the mouse by manual rotation of the top relative to the base to open the enclosure by substantial alignment of the apertures, the enclosure being held open against the force of the biasing means by engagement of the lever arrangement with a stop means, the mousetrap being activated to trap the mouse by the

Abstract: With reference to a preferred embodiment as depicted in FIG. 4, the present invention provides a mousetrap comprising a first part (5) and a second part (10) that together define an enclosure wherein the first part (5) and the second part (10) are operably connected to a first biasing means (60). Within the enclosure is retained a lever (45) having a first end (47), a bridge (49), a pivot means (40), a releasable catch means (57) and a second biasing means (55). The mousetrap is able to be set from a closed to an open position by rotation of the first part (5) in relation to the second part (10) against the force of the first biasing means (60). The mousetrap is held in the open position, ready to receive a mouse, by engagement of the releasable catch means (57) located on the lever (45) with a stop means (59) located on the first part (5). The mousetrap is activated by movement of the lever (45) by the mouse so that the releasable catch means (57) disengages the stop means (59).
