| 20090296880 | DISTORTION CORRECTION METHOD FOR LINEAR SCANNING X-RAY SYSTEM - Imaging apparatus comprises a radiation source arranged to generate a divergent imaging beam and an associated radiation detector mounted on a C-arm which can rotate. A first drive is arranged to move the radiation source and the detector relative to a subject in a scanning direction to generate output signals from the detector, thereby performing a scan generating image data containing distortion in a direction transverse to the scanning direction. A second drive is arranged to rotate the C-arm, to change the orientation of the radiation source in a direction transverse to the scanning direction incrementally between repeated scans, thereby to generate a plurality of sets of image data. A processor, which can be a PC or a dedicated processor, is provided for processing each set of image data to obtain equivalent parallel imaging beam data therefrom, corresponding to a given angle in the divergent imaging beam, and for combining a plurality of said equivalent parallel imaging beam data to generate a synthesized parallel imaging beam image. The apparatus includes a display for generating a visual display of the synthesized parallel imaging beam image. The resulting synthesized image has the distortion removed and measurements can be made from the image. The invention extends to a method carried out with the apparatus. | 12-03-2009 |

| 20110155549 | Pushbutton - A pushbutton comprises a cap, a housing with an interior space, a reset element for connecting the cap to the housing, and an electrical switch element. The cap is able to move from a rest position to a switch position relative to the electrical switch element so that the electric switch element, which is disposed inside the housing, can be actuated. The reset element returns the cap to the rest position after actuation. The reset element comprises a first spring means and a second spring means, wherein the first spring means is offset relative to the second spring means at least in the direction of the actuation axis of the cap. | 06-30-2011 |

| 20110011141 | METHOD FOR TREATMENT OF OIL AND/OR GAS FIELD WASTE AND BY PRODUCT MATERIALS - A method for the treatment of oil and/or gas field waste and by product materials, the method comprising composting the waste materials. The present invention is typically suited to the treatment of waste and by-product materials from oil and gas wells that are contaminated by organic compounds, such as hydrocarbon residues, either from oil based drilling muds, or from hydrocarbons produced from the well. The composting is typically accomplished by an endogenous microbial population on the composted mixture, and optionally a feeder material to provide N and C sources for the microbes. The composting operation is typically carried out in a composting chamber, and typically an auger or some other tilling device is used to mix the material within the composting chamber. | 01-20-2011 |
