Abstract: ABSTRACT      A method for the continuous fabrication of blankets or sheets of expanded phenolic resin displaying a hard skin on each of their sides, according to which a mixture, comprising in particular a resole resin, a blowing agent and a hardening catalyst is placed on an essentially flat surface of a moving element, is brought to foam and is conformed between two par-allel surfaces entrained in the same direction, the lower sur-face being situated in the same plane as the surface of the moving component, characterized in that, in a first stage, the mixture is brought into free air towards the conformation surfaces by being submitted to a heating so as to have it expand and then the expanded mass is conformed by exerting a pressure on its free side, at the moment of entry between the conformation surfaces, and the hardening of the resin is completed while maintaining the pressure and the heating.

Abstract: ABSTRACT Carbonaceous materials are pyrolyzed by simultaneous feed of the carbonaceous materials and a particulate source of heat to a cyclone reactor-separator wherein the centrifugal forces separate the vaporized product of pyrolysis from the solids.  The carbon in the solids is partially combusted for recycle to the cyclone reactor separator and the vapourized products quenched and recovered.  The yield of liquid hydrocarbons may be maximized.

Abstract: ABSTRACT OF THE DISCLOSURE    High-speed hardware is employed to: subdivide an input angle into a series of smaller subangles according to the sine approximation algorithm:            SIN(INPUT) = SIN(A) + COS(A)SIN(B) + COS(A)SIN(C) +                       COS(A)SIN(D); process the above terms separately through individual look-up tables; and sum the table results to provide the sine function of the input angle.        The above algorithm is derived from a series of approximations re-lating to the sine and cosine functions of very small angles.  The relative sizes of the above subangles is expressed by:             A >> B > C > D           The actual size of each subangle is dependent on the number of in-put bits, the size of the look-up tables available, and the accur-acy desired.

Abstract: ABSTRACT OF THE DISCLOSURE    A coating formed on a surface of an article, which is heated during use as typified by a cooking device, to accomplish catalytic oxidation decomposition of oil and grease spattered thereon.  The coating is fundamentally a porous matrix layer of an inorganic binder having a matte surface and comprises, in the form of uniformly dispersed particles, an oxidation catalyst and a non-discoloring material, for example a ferrite, which has the effect of concealing a change in color of the oxidation catalyst resulting from its catalytic action.          Preferably the coating comprises additonally a solid acid catalyst such as a zeolite as a decomposition-inducing catalyst in order to acquire an improved catalytic self-cleaning ability at relatively low tem-peratures such as 200-300°C.

Abstract: ABSTRACT         This specification discloses oral or edible compositions and their manufacture.  It includes foods and pharmaceutical preparations containing sugar and very little water.  In particular it discloses hygienic agents for tooth and mouth care.  It is known that in the oral cavity foodstuffs, beverages and medicaments with a high sugar content lead, in the presence of micro-organisms, to the formation of so-called "plaques" and acid decomposition products which severely attach tooth enamel.  This effect is known by the name caries.  Caries is understood to be an initial attack on the surface of teeth which are then progressively destroyed by cavities being formed therein.  Thus the specification discloses an oral or edible composition which composition contains sugar and very little water and having a content of lactate dehydrogenase which limits promotion of tooth decay.  Thes preferably com-prises foodstuffs with a residual moisture content of 0.1 to 2%.  It includes foodstuffs which contain a proportion of naturally occurring sugars, such as sucrose, glucose, fructose and the like t as well as sugar alcohols, as sugar substitutes. Foodstuffs containing sucrose are particularly preferred.  If appropriate, foodstuffs or confectionery or pharmaceutical preparations which contain no customary sugars can be used. These can be materials which are sweetened on the basis of sugar substitutes, for example saccharin, cyclamate, protein sweeteners extracted from tropical plants, xylitol and the like.
