Title: Tubular expander with lubricant delivery system
Inventor: SHUSTER MARK
IPC: B21D39/20
Filed: 2004-09-07
Abstract: In a system 7200 for lubricating the interface between an expansion cone 7202 and a tubular member 7230 during an expansion process, the cone 7202 is displaced relative to the expandable tubular 7230 by injection of a pressurized fluidic material 7232, which may include lubricant, into and through a passage 7228a of a tubular member 7228. The fluidic material flows into a annular chamber 7234 then, at a pressure predetermined by spring-biased check valves 7226a,b or the like, into an annular chamber 7236 leading to external grooves 7224a,b,c of the expansion cone 7202. A high-pressure gaseous expansion of vaporising lubricant caused by capacitor discharge in an annular chamber (figure 67) may be used to increase the lubricant pressure and create a pressure impulse of lubricant flow.

Title: Chain pin having an outer two part chromium carbide layer having recesses
Inventor: MIYANAGA SHOTA
IPC: B21L9/02
Filed: 2007-08-29
Abstract: The pins of a roller chain or rollerless bushing chain for an automobile engine are subjected to chromizing treatment that forms a two part outer chromium carbide layer having a thick inner section composed primarily of Cr7C3 and a thinner, outermost, layer composed primarily of Cr23C6. The outer layer has convex protrusions and concave recesses. The protrusions are partially removed by barrel polishing to a level such that the depth of each recess is sufficient, but not substantially greater than necessary, for an inclusion in the lubricating oil received therein to be substantially entirely below the outer surface of the pin, thereby making the surface pressure exerted by portions of the pin on a surrounding bushing substantially as small as possible without exposure of inclusions beyond the outer surface of the pin.

Title: Video processing hardware architecture for video conferencing
Inventor: EVANS SIMON JAMES WINN
IPC: G06F15/173
Filed: 2007-11-20
Abstract: A video processing hardware architecture for a multipoint control unit (MCU) is presented wherein a motherboard 20 carries a field programmable gate array (FPGA) connected to a plurality of additional video signal processors. These additional processors, illustrated by daughterboards 22, are interconnected with a plurality of high bandwidth (ie   /  3Gb/s) links 26. Each daughterboard typically comprises a field programmable gate array (FPGA) (32, figure 4) and four digital signal processors (DSP) (28, figure 4). Also provided are stream processors P (36, figure 4) which may carry out compression, composition, motion compensation, encoding and other operations, which removes some of the processing load from other DSPs 28, and avoids using up available bandwidth by passing data between processors. The hardware architecture presented ensures that data processing is ideally performed by local DSPs thereby avoiding local bottlenecks, and where necessary, data may be moved in an efficient manner using the high bandwidth links. This architecture is particularly suited to video conferencing systems wherein the MCU is required to provide different content to each participant, dependent upon the capabilities of their local equipment. This overcomes the disadvantage of present MCUs which lack the processing capability or internal bandwidth availability to meet these processing-intensive demands. By processing the data internally using intelligent multicasting decision, intelligent scaling and compression decisions and acknowledging that the video data may be compressed without loss of visual quality, processing and bandwidth requirements may be met.

Title: A method of isolating and recovering thiol-containing compounds
Inventor: CLERY ROBIN
IPC: C07C319/06
Filed: 2009-10-02
Abstract: A method of isolating and recovering thiol-containing compounds from a natural material, especially a plant extract or an essential oil, comprises the treatment of the mixture with a compound of formula (I):X-Y-S-S-Z (I)in which X is a support substrate; Y is a connecting moiety; S is a sulphur atom; and Z is a chemical moiety which, in combination with the sulfur atom to which it is attached, forms a leaving group S-Z. Thiols may react with disulfide (I) to displace —SZ; the thiol may be subsequently released from the resin by treatment with a reducing agent. The support substrate (X) may be a styrene based polymer or copolymer, a silica or an alumina. Z may be 2-pyridyl. Compound (I) may be produced by taking polymer bound thiophenol and adding 1,3-dibromo-5,5-dimethylhydantoin and subsequently mixing the resin with 2-mercaptopyridine. The method may be useful in trapping and isolating thiol containing components in a mixture. The method may be superior to agarose based systems.

Title: Phosphoric acid recovery
IPC: C01B25/234
Filed: 1965-03-10
Abstract: A process for recovering phosphoric acid from an aqueous solution thereof comprises treating the solution with an extracting solvent capable of extracting phosphoric acid from an aqueous solution thereof having a concentration of H3PO4 above a threshold value of 35%, whose capacity for extracting phosphoric acid from water varies inversely to a temperature and which does not extract phosphoric acid from an aqueous solution thereof having a concentration below a threshold value of 35%, a temperature of the treatment being low enough for the formation of a clear homogeneous extract phase distinct from a residual aqueous phase, separating the extract phase from the aqueous phase, raising the temperature of the extract phase to that at which it separates into a lower layer containing phosphoric acid and an upper layer containing solvent, and separating the lower layer from the upper layer. Suitable solvents may be ester, ketones, glycol ethers and ethers, such as ethers and esters containing 2-15 carbon atoms.  Ethers specified are diethyl, di-isopropyl, di-n-butyl, isopropyl-n-butyl, di-n-amyl and di-isoamyl ethers.  During the heating to separate the aqueous acid from the solvent a small amount of water or purified phosphoric acid may be added.  The lower temperature for the extraction of the acid may be obtained by evaporating in vacuo an adequate proportion of the solvent added to a technical-grade acid.
