A magnetic field is induced in the tube having lines of flux which flow through the polepieces along a magnetic axis. Heat formed within the circuit flows through the spacers to an external planar surface along a thermal axis, which is non-coincident with said magnetic axis. In an alternative embodiment, a plurality of the tubes can be combined into a common system for focusing a plurality of electron beams. The tubes within the common system share heat sinks which attach to the planar surfaces.

Abstract: A process for preparing a coal-water fuel from a low rank coal. The first step of the process provides for an aqueous slurry containing particles of the low rank coal. A quantity of an agglomerating agent in the range of about 10% to 30% weight to dry ash - free low rank coal weight is added to the slurry to produce a mixture. The mixture is then agitated to form agglomerates. Following separation of the agglomerates, the agglomerates are contacted with steam or an inert gas having a temperature in the range of about 250°C to 420°C at substantially atmospheric pressure to produce partially deoiled agglomerates containing less than about 7% by weight of residual bridging liquid and having a moisture capacity reduced by a factor of at least about 2.5 at a relative humidity of 96% compared to the moisture capacity of the low rank coal. A first amount of the partially deoiled agglomerates is then first wet milled in the presence of water and at least one anionic dispersant, wherein the concentration of the first amount of the partially deoiled agglomerates in water is about 35% to 55% by weight, to produce a micronized fraction of the first amount of the partially deoiled agglomerates having a maximum size of about 15 to 25 micrometres and an average diameter of about 4 to 10 micrometres. Finally, a combination of the micronized fraction of the first amount of the partially deoiled agglomerates and a second amount of the partially deoiled agglomerates is final wet milled in the presence of water, wherein the combination is comprised of about 20% to 50% by weight of the micronized fraction, to produce the coal-water fuel which contains solid particles having a maximum size of about 250 to 300 micrometres and an average diameter of about 15 to 30 micrometres. In a further embodiment, the process utilizes a paste in place of the agglomerates, the paste being formed by mixing particles of the low rank coal with a quantity of a bridging liquid.

Title: Filter for free-flowing materials, in particular plastic melts containing impurities
Inventor: SCHULZ HELMUTH
IPC: B29C48/694
Filed: 1993-02-12
Granted: 1998-08-04
Abstract: Described is a filter for plastic melts containing impurities, the filter having a housing in which a cylindrical or conical filter element is mounted so that it can be rotated by a drive shaft about its longitudinal axis. Lying against the outside surface of the filter element is a scraper which surrounds the filter element in the form of a spiral. The material to be filtered is fed into the filter element from the outside through an inlet port. The filtrate passes through apertures in the filter element into the central cavity inside the filter element, from where it is removed through an outlet port. The impurities cannot pass through the apertures in the filter element, but collect on the outside surface of the filter element and are conveyed by the fixed scraper to a discharge port. This gives a simple design which is reliable in operation.
