Granted: 1989-10-12
Abstract: Organic sulphides are extremely malodorous compounds that are found in gaseous or aqueous effluents from many industries such as paper and pulp manufacture, hydrocarbon refinering, tanneries, and in the synthesis of organic sulphur compounds. Their removal is necessary before such effluents can be discharged into the environment.In the present invention their removal is effected using hydrogen peroxide at a pH controlled to pH 8.5 to 11.5 and in the presence of a catalytic amount of a soluble tungstate. Such a process is especially applicable to the removal of dia-Ikyl disulphides, which are regarded as being especially difficult to remove oxidatively. In especially preferred conditions. the pH is about pH 11 and about 3-4 moles H<sub>2</sub>0<sub>2</sub> is used per mole equivalent of sulphur, in the presence of at least 20 ppm sodium tungstate las W).

Abstract: The invention relates to a spark-ignition internal combustion engine having a combustion chamber which, at least in part, presents surface areas (10) which have been treated to reduce the octane number requirement of the engine. 
<??>The surface area to be treated may, for example, be either blasted or etched to produce surface depressions, and is then flame sprayed with copper particles to form heat-reflective surfaces. At least this latter method results in solely low-temperature heating of the walls of the combustion chamber, which can be advantageous in the case of diesel engines, but not in the case of Otto-cycle engines. 
<??>The improvement in such engines afforded by the invention is that the surface areas (10) are instead provided with at least one layer (12) which presents to the combustion chamber (1) a defining surface (9) which exhibits an extremely low reflectivity to electromagnetic waves in the wavelength range of about 0.2-7.0 microns, and which also results in diffuse reflection of non-absorbed incident waves (14).

Abstract: The progressive spectacle lens has one or more surfaces contributing to improvement in efficiency from the distant, via the progression, to the close zone. The radii of the intersecting curves of the surfaces, contributing to the increased efficiency decrease as a function of the distance from the main meridian on the front surface in the distant zone, and increase in the close one, the converse applying to the eye facing side. The pattern, to which the radii alter on both surfaces, is determined by two formulae, the direction of alteration of the radius changing at 14 to 26 mm from the main meridian.
