Patent BE-901657-A (BE)
IPC: B01J8/40
Filed: 1985-02-05
Abstract: A system for reacting solid particles flowing under gravity through a thin walled enclosure has at least one fluid flowing through the enclosure in a counter-current to the flow of the solid particles. The feeding of the solid particles into the enclosure and the discharging therefrom of the converted ash particles may be adjusted. A particle bed is controlled by feeding the fluid into the enclosure so that it has to go through a substantial part of the bed thickness. The enclosure is vibrated to obtain a vibrated particle bed, with the vibrations being directed along a direction which lies at substantially a right angle to the vertical.

Title: Reciprocating light for dance hall - governs direction of light beam by volume of music
IPC: A63J17/00
Filed: 1985-10-11
Abstract: The audio frequency music signal is fed via a low pass filter to an amplifier, to select only the bass rhythm. The amplifier output is fed via a rectifier and buffer to a thyristor circuit which controls an electric motor. The motor shaft is attached to one end of a flexible belt. The other end of the belt is wrapped around a spindle which is mounted in a frame. The spindle is attached at right angles to a lever which is held back against the frame by a spring. - When the music amplitude is hight, it causes the motor to wind the belt around its spindle, thus turning the spindle and swinging the lever. When the thyristor stops conducting, the spring pulls the lever back and the belt unwinds on the motor shaft The light source is mounted on the outer end of the lever, and its beam sweeps backwards and forwards in time to the music.

Title: Partial combustion in carburation - improved exhaust in i-c engines
IPC: F02M27/02
Filed: 1972-06-19
Abstract: Process for operating a combustion engine with partial combustion in a carburation reactor and residual combustion in the engine, involves feeding a partial flow of air to the carburation reactor from the air inlet pipe fo the engine, passing an impoverished fuel/air mixt to the carburation reactor, converting the mixt into a soot free combustible gas, and supplying this, with air, in the form of a homogeneous gas/air mixt. The process reduces the amt of toxic substances, eg.g. CO, hydrocarbons, aldehydes, organic acids and N oxides, in the exhaust gases. The fuel used is a base petrol (e.g. direct distillation petrol) which is comparatively cheap, leadfree, and pref. contains only small amts. of aromatics and olefins.

Abstract: ABSTRACT OF THE DISCLOSURE      A process and apparatus for refining platinum group metal concen-trate and the separation therefrom of silver and the majority of base metals which are present in them are provided herein.  The process aspect comprises the steps of:  (a) contacting a solid particulate mixture of base metal, silver and precious metal components, any of which may be in metallic or in chemically combined form, with substantially anhydrous sulphuric acid at a temperature which is sufficiently high (e.g. from 140°C to 250°C) to convert most of the base metal and silver components to water soluble sulphates while leaving the precious metal components in an essentially water insoluble solid state and (b) separating the water soluble sulphates from the solid precious metal-containing components by contacting the product from step (a) with water (e.g. in the form of a dilute aqueous mineral acid solution) and dis-solving therein the water soluble sulphates formed in step (a).  The appara-tus for carrying out the above process comprises:  (a) reaction chamber having (b) separated inlet means for particulate solid and substantially anhydrous sulphuric acid;  (c) means for stirring together the solid and the acid in the reaction chamber, and (d) outlet means for product, the outlet means having an opening into the chamber above the level of the sulphuric acid-solid mixture. This provides a simple and effective refining process and apparatus whereby a substantial portion of the silver and base metal components present in the mixture are separated from the precious metal com-ponents, and the concentration of the precious metal is thereby significantly increased.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved prepasted wall-paper trough assembly having a thin walled polystyrene tray with a horizontal bar.  The bar is engaged in place in the tray by forcing the ends of the bar downward into channels formed in the ends of the tray.  The width of the bar is slightly smaller than the width of the channels and therefore the channels resiliently engage the ends of the bar.  Thus, the "memory" factor of the plastic which, when deformed attempts to return to its original shape holds the bar in place during the wallpapering operation.          The assembly is simple and its shape enables it to be made ex-tremely economically by vacuum forming.
