Filed: 1989-04-24
Abstract: An effective process is provided for cleanly and safely combusting coal or other carbonaceous material in a manner which enhances the environment by reducing emission of pollutants. In order to reduce nitrogen oxide and sulfur oxide emissions during combustion, combustion is carried out in the presence of one or more additives comprising an alkali metal salt, such as sodium chloride. To further enhance the reaction and removal of sulfur oxides and nitrogen oxides, the additive can include an iron-containing compound, such as iron oxide, and/or a metal oxide, such as manganese oxide.

Abstract: A system for automatically positioning a plurality of tool-holding carriages (32) along an elongate guide member (10) utilizes a single drive member (36) to move all of the carriages simultaneously. The carriages (32) each have clutches (50, 52) for selectively engaging or disengaging the drive member (36) so that the carriages (32) can be moved relative to each other by the drive member (36), and can be moved simultaneously in opposite directions along the guide member if desired. The drive member (36) is capable of moving each carriage (32) throughout its respective maximum range of movement with a continuous motion, without any reversal of the drive member of any disengagement of the respective carriage from the drive member. Each carriage (32) has an electrically-powered position sensor (54) capable of transmitting different discrete signals for different positions of the carriage so that it provides absolute indications of position rather than indications which are relative to some reference position.

Abstract: Degreasing of shaped ceramic bodies containing a large quantity of paraffin wax, comprising the step of constant-temperature heating for a period of time appropriately determined according to the size and shape of said shaped ceramic bodies, said temperature ranging immediately below the temperature of the beginning of contraction of the shaped ceramic bodies, essentially in a low temperature region, wherein the contraction occurs due to liquefaction of the paraffin wax, and optionally in a high temperature region, wherein the contraction occurs due to thermal decomposition of the paraffin wax. The stress build-up by heating in the shaped ceramic bodies is prevented, and the temperature gradient between the surface and the inside is leveled, so that crack-free bodies are obtained with a shortened degreasing schedule.

Abstract: In a fluid machine for incompressible media with a delivery chamber (4) arranged in a fixed housing (1, 2) and formed in the manner of a circularly extending slot, a displacer (8) associated with the delivery chamber and likewise of circular design is held on a disc-shaped rotor (3) which can be driven eccentrically in relation to the housing. The displacer touches the inner and outer circumferential walls of the delivery chamber at at least one sealing line advancing continuously during operation and conveys the medium from an inlet (6) to an outlet (7). The inlet and the outlet are separated from one another by a web (5) extending radially in the delivery chamber (4). A cross-keyed coupling (9, 10) is provided for the purpose of guiding the displacer relative to the housing and, for the purpose of driving it in a circle, a wobble rod (12) is connected to a driving crank mechanism (13). In the region of the web (5), the working chambers (27, 28) communicate at the inlet (6) and at the outlet (7). In the majority of their circumference, the displacer (8) and the delivery chamber (4) have a pure circular shape. In an angular range of at most 20 DEG , the inlet and outlet ends of the displacer and of the delivery chamber have considerably smaller radii of curvature than those of the majority of their circumferences.

Abstract: In order to prepare alkali metal phosphate solutions having a fluorine content, relative to P2O5, of less than 20 ppm, first crude phosphate is digested using sulphuric acid, and the calcium sulphate is separated off from the crude phosphoric acid. An alkali metal compound is then added to the crude phosphoric acid, and the precipitated solid is filtered off from the mixture. The pre-purified crude phosphoric acid is neutralised until reaching a pH of at least 7, and any solid formed is separated off. The resulting alkali metal phosphate solutions having a P2O5 content of 10 to 30% by weight are brought back to a pH of between 4.8 and 6.0 using phosphoric acid. After heating the solutions to 60 to 120 DEG C, 1 to 6% by weight, relative to the weight of the solution, of an alkaline earth metal/oxygen compound is stirred into the alkali metal phosphate solutions. Finally, after a residence time of 0.5 to 4 hours, the precipitated solid is separated off from the alkali metal phosphate solutions by filtration.
