Abstract: A ferrous metal object separator (10) is removably attachable to a conveyor which transports a moving stream of non-ferrous material (26) (e.g. wood chips) in which some ferrous metal objects (30) (e.g. screws, nuts, broken machinery parts, spikes, nails, steel filings, steel chips, etc.) may be commingled. The separator, which has a non-ferrous body, has an inclined surface (19) extending upwardly from a leading edge (12) to an abrupt traili ng edge (14). A separating magnet (24) embedded adjacent the trailing edge magnetically retains the ferrous metal objects (30) without substantially impeding transport of the non-ferrous material (26) along the conveyor. A fastening magnet (16) embedded in the separator removably magnetically faste ns the separator on the conveyor.

Abstract: Systems and methods for determining the elbow or Ct value in a real-time, or kinetic, PCR amplification curve data set. A PCR data set may be visualized in a two- dimensional plot of fluorescence intensity vs. cycle number. The data set may be adjusted to have a zero slope. In one aspect, a data set is fit to a double sigmoid curve function with the function parameters determined using a Levenberg-Marquardt regression process. The determined parameters are used to subtract off the linear growth portion from the data set to provide a modified data set. For multiple data sets, all the data curves can be aligned in this manner to have a common baseline slope, e.g., a slope of zero. A rotation transform is applied to a modified data set to rotate the data about a defined coordinate such as the origin so that the data point representing the Ct value becomes a minimum or a maximum along the intensity axis. The data point representing the elbow or Ct value of the curve is identified, and this data point is then rotated back and the cycle number of the data point is returned or displayed.

Abstract: A spray gun (1) has a fluid reservoir (11) which contains a removable liner (13). The liner (13), which may be thermo/vacuum-formed from a plastics material, is a close fit within the interior of the reservoir and collapses as fluid is withdrawn from within the liner during operation of the gun. Preferably, the liner has a comparatively-rigid base and is capable of standing, unsupported, outside the reservoir. The side walls of the liner are preferably thin in comparison to the base and can be collapsed for disposal of the liner. The reservoir (11) has a removable lid (15) and is capable of standing, inverted, on its own so that it can be filled with fluid. The lid (15) also functions to secure the liner (13) in the reservoir and, at the end of a spraying operation, the lid (15) and the liner (13) are removed together from the reservoir (11) and discarded, thereby simplifying the cleaning of the spray gun.
