Abstract: An apparatus for purifying polyketones includes a pressure vessel 2 which communicates with a water supply line 6 for delivering pressurised water into the vessel 2. Downstream of the vessel 2 is a water drain 12 for removing water to waste. In use, a sample of polyketone is placed in the vessel 2 and liquid water at high pressure (e.g. 60 bar) and high temperature (e.g. 260° C.) is caused to flow through the vessel whereby relatively pure polyketone for example having relatively low sodium, phosphorus and sulphur impurities may be prepared.

Abstract: Embodiments of the present invention relate to a data processing system including means to play an interruptible or skipable video sequence; and a random number generator for generating a random number associated with an interruption of the interruptible or skipable video sequence.

Abstract: The invention provides compounds of formula I, R1—OP(O)(OH)2  I wherein R1 represents the non-hydroxy portion of a triazole antifungal compound of the type comprising a tertiary hydroxy group; or a pharmaceutically acceptable salt thereof. The compounds of the invention are useful in the treatment of fungal infections, and have good aqueous solubility.

Abstract: An authoring method for creating an audiovisual product. The method has three main stages. The first stage defines components implicitly representing functional sections of audiovisual content and transitions that represent movements between components. The second stage expands the components and transitions to provide a set of explicitly realised AV assets and an expanded intermediate datastructure of nodes and links. Each node is associated with one of the AV assets and the links represent movement from one node to another. The third stage creates the audiovisual product in a predetermined output format, e.g. DVD-Video, using the AV assets and the expanded intermediate datastructure of the nodes and the links.

Abstract: An active optical network switch having a switch module, a plurality of uplink modules and a plurality of downlink modules connected to a backplane for connecting the modules and passing signals among them. A CPU module assists in managing the routing of traffic signals by the switch module; said modules and backplane are enclosed in an environmentally hardened housing. Six downlink modules may include four downlink ports each, for connecting the switch to twenty-four subscribers. Multiple switches may be daisy-chained together; one being a master and the remainder being slaves, to increase the number of subscribers that are served by an uplink fiber/pair. Dense Wavelength Division Multiplexing may aggregate traffic signals between many subscribers and a CO/head end along a single backhaul fiber. Switch software may provide “network edge” functions including traffic shaping, policing, filtering and aggregation, and address control.

Abstract: In order to provide wider biaxially-stretched geogrids having high primary direction (PD) strength, crotch-forming zones of a starting material which is at least 2.0 mm thick have protuberances (6). On strectching, PD orientation passes right through the junction (27) but the protuberance (6) causes the orientation ratio of the crotch edge to decrease significiantly as orientation enters the central part of the crotch edge. After a secondary direction stretch of at least about 1.5:1, the thickness of the central part of the crotch edge is not reduced by more than about 20%. The stretching does not reduce the thickness of any point along notional ridge lines (31) to such an extent that the ratio of finished thickness to starting thickness at that point mid-point. In the biax geogrid (25), the junction mid-point is significantly thicker than the PD is less than about 80% of the ratio of finished thickness to starting thickness of the junction strand mid-point.
