The guides are distributed over the breadth of the drafting frame, spaced at intervals on the appropriate mounting...

The navigational aid system has a CRT display (26) onto which is shown a route map of the stated region defined by the user. The user has optical inputs (27, 29) to define start and end points for a required journey. The system is operated by a controller (1) that reacts to inputs generated by a number of switches. Route maps are provided in the form of data stored on CD discs. Instantaneous posit...

A method of concentrating waterborne pathogenic organisms from water potentially contaminated by dilute densities of the organisms is described. Potentially contaminated water is directed along an elongated flow path (34) which rests generally within a plane perpendicular to an axis of rotation, and is subjected to centrifugal forces by rotating the flow path about the rotational axis. The method ...
