Abstract: An automatic data plotting apparatus consists of three main parts: a processor; a serial and parallel interface; and a plotter. The plotter is a flat-bed X-Y plotter. The data processor is programmed to handle one or more data inputs and instruct the plotter to record information relating to the data inputs on a plot. The processor translates the incoming data into times, bearings, tracks and any other characteristics. A pause facility is provided to suspend plotting, the incoming data being stored in a data store while the pause facility is in operation and being recorded on the plot when the pause is discontinued. An automatic data plotting apparatus provides a focal point at which incoming information can be co-ordinated and displayed. The displayed information can then be evaluated and/or stored for later analysis.

Abstract: The life of a joint in splice jointed conveyor belting is increased by providing a belting wherein the joint is protected by a covering of a breaker fabric having substantially different stretch characteristics in warp and weft directions. A suitable breaker fabric is a warp knitted fabric having a warp to weft elongation ratio of from 1:2 to 1:30, preferably 1:3 to 1:20, for example approximately 1:15. The conveyor belting may comprise a solid woven textile fabric core impregnated and/or coated with polyvinyl chloride and the joint may be one formed by finger splicing.
