Abstract: A method for the total precipitation of valuable metals from a leaching solution that has been acidified with sulphuric acid and that is substantially free from impurities, by neutralising the solution with lime and/or limestone.  Neutralisation is effected in at least two stages, wherewith only partial precipitation is effected in the first stage, and wherewith full precipitation of remaining valuable metal content is effected in the last stage, by adding a surplus of neutralisation agent. Slurry containing precipitates and remaining solid neutralisation agent formed in the last stage in the neutralisation process is returned to the first neutralisation stage, possibly after re-dissolving the slurry in the incoming acid leaching solution. The amount of slurry returned together with any further neutralising agent added manages said partial precipitation of the valuable metal content.  Metal hydroxide/gypsum precipitate free from neutralising agent and formed in the first stage is washed and then removed from the process for winning metal therefrom in some known manner.

Title: Method and architecture for converting mpeg-2 4:2:2-profile bitstreams into main-profile bitstreams
Inventor: CHEN XUEMIN
IPC: G06T9/00
Filed: 2000-02-16
Granted: 2011-07-05
Abstract: A system for converting the color format of a digital video bitstream. The system accounts for the allowable formats of the pre- and post-conversion bitstreams, including quantizer (355) precision level, and whether luma and chroma data have separate quantization matrices (385, 390), or share a common quantization matrix. In a particular implementation, an MPEG-2 4:2:2P  bitstream having a color format of 4:2:2 or 4:2:0 is converted to an MP  bitstream having a color format of 4:2:0. Coding efficiencies are achieved by using the luma quantization matrix (390) to re-quantize the chroma data, and re-using luma motion vectors MV for performing motion compensation (320, 325, 510) of the chroma data. Further efficiencies can be achieved by representing a 4:2:2 reference picture in a 4:2:0 format for converting intercoded frames, and changing the position of a pixel downsizing filter (340) and clip function (335). Adjustment (130, 230, 382), of the quantization precision is provided as required. A transcoding function (800) can also be achieved.

Abstract: An auxiliary elastomeric sealing adaptor is dis- closed which effectively provides a high degree of sealing, and prevents fuel leakage, between the metering valve stem and the tool stem components of a fuel-cell powered fasten- er-driving tool despite bending; tilting, or pivotal move- ments of the metering valve stem attendant a fastener-firing operation. In addition, the incorporation of the elastomeric adaptor between the stem components reduces the need for high tolerance manufacturing techniques and also enhances the service lives of the stem components. The sealing adapt- or is mounted upon the free or distal end portion of the metering valve stem and is seated within a counterbored re- gion of the fastener-driving tool stem.
