Abstract: A process for producing silicon carbide platelets and the platelets so produced. The process comprises reacting particles of a non-graphitizable form of hard carbon containing 0.5-1.5% by weight of aluminum and at least 0.2% by weight of iron (preferably anthracite coal, most preferably Pennsylvania anthracite), with silica or a silica precursor at a temperature in the range of 1900 - 2100 DEG C under an inert atmosphere. If the carbon contains 0.2 - 1.0% by weight of iron, 0.1 - 10% by weight of boron, relative to the weight of SiO2, is added (if not already present). The carbon is in the form of particles of less than 50 mu  and the silica or precursor is preferably in the form of particles of less than about 1  mu . The weight ratio of silica to carbon is greater than 1.67:1. The resulting platelets are substantially unagglomerated and preferably of a size of less than 50 mu  with an aspect ratio greater than 5. The platelets can be used as reinforcements for ceramic and metal matrix materials.

Abstract: PCT No. PCT/EP90/00335 Sec. 371 Date Oct. 25, 1990 Sec. 102(e) Date Oct. 25, 1990 PCT Filed Feb. 28, 1990 PCT Pub. No. WO90/10086 PCT Pub. Date Sep. 7, 1990.This invention is directed to a smelting plant with shaft-like charging material preheater. In a smelting plant with an electric arc furnace (1) and a charging material preheater (2) of shaft configuration arranged laterally on the furnace, the outer walls of the charging material preheater in the lower region thereof are formed by the vessel wall (5) of the furnace while in the region thereabove they are formed by the walls of a shaft which is fixed in a holding structure (27). By a horizontal relative movement between the furnace vessel (3) and the holding structure (27) together with the vessel cover (6), without being impeded by the shaft (10) charging material can be charged from a scrap basket directly into the furnace vessel or through the displaced shaft into different regions of the furnace vessel (3). Charging material can be retained in the shaft by means of a blocking member (51) therein, and heated up during the refining phase.

Abstract: An adaptive system and method for reducing interference in a signal received from an array of sensors. Adaptive filters are used to generate cancelling signals that closely approximate the interference present in the received signal. The adaptive filter weights are converted into the frequency domain where the frequency representation values in a selected frequency range are truncated to avoid signal leakage involving narrow band signals. Deodorizing filters are used to produce the cancelling signals having a flat frequency spectrum. Normalized power difference is used limit the operation of the adaptive filters to the case where there is some directional interference to be eliminated.
