Abstract: An optical coupler comprising N (where N stands for an integer of not less than 2) optical fibers having one end coupled and the other end branched, and N optical coupler parts. The coupling end of each optical fiber comprises two planes angled at 360°/N, including a fiber-abutting plane inclined at an angle ϑ to the optical fiber axis, and also a light-coupling plane perpendicular to the abutting plane. Each of the optical coupler parts is constructed by inserting an optical fiber in an optical fiber-retaining hole (12) of a block (1, 2) and forming a fiber-abutting plane and a light-coupling plane perpendicular to the abutting plane. The fiber-abutting planes of the optical coupler parts are eengaged with each other to construct an optical coupler.

Abstract: A multiple light valve (MLV) projector apparatus for producing a color display includes two separate light valves of the Schlieren dark field type. One of the light valves produces a first primary color, for example green, and the other light valve, including an array of lenslets (19) and a cooperating input mask (60) having slots (62,66) extending in orthogonal directions, produces two other primary colors, for example red and blue. In such an apparatus the output brightness is usually limited by the red light output. An improved two-color light valve is provided having an input (and complementary output) mask (60) which optimizes the transmission of the first, second and third diffraction orders through the slots (62) in the portion of the input mask which transmits red light, these slots being asymmetrically disposed relatively to the lenslets in the corresponding direction. Such an optimization provides a substantial increase in red light output compared to a conventional input mask.

Abstract: A method of forming an electrical heating element in the form of an electrically non-conductive supporting body onto which an electrically resistive material is deposited, the method comprising the steps of preparing a dry metal powder of irregularly shaped metal particles of widely varying sizes, in the range 20-150 microns, roughening the surface of a supporting body onto which a heating element is to be formed, pre-heating said surface of the supporting body to a temperature within the range of 150-250°C and flame spraying the dry metal powder onto said heated surface of the supporting body in a plurality of passes over the supporting body. The effective resistivity of the flame sprayed deposit is predetermined by adjusting the amount of oxidation on the surfaces of the metallic particles sprayed onto the supporting body. The amount of oxidation on the surfaces of the flame sprayed particles, and hence the resistivity of the sprayed deposit, can be varied by selecting the size range of the particles used, within said range of 20-150 microns. Alternatively the amount of oxidation on the surfaces of the flame sprayed particles can be varied by blending selected alloys into the powder to by sprayed such as to adjust the quantity of conductive oxides present on the sprayed particles.

Abstract: When analog video signals including half-tone video signals and binary video signals are converted into a video signal having an increased number of scanning lines, a video signal processor of the invention does not lose vividness in the binary video display. In this processor the input video signals are divided into half-tone video data and binary video data. The portion in the half-tone data, from which the binary data were removed, are filled with the half-tone video data appearing just before the binary video data start. The half-tone video data and the binary video data are separately stored in a storage means. The half-tone video data are subjected to an ordinary analog enlargement interpolation such as linear interpolation, and the binary video data are subjected to a binary enlargement interpolation. The resultant half-tone video data and binary video data are combined together again.

Abstract: The invention relates to a process for the elimination or diminishing of halogenated aromatics, in particular polychlorinated phenols or polychlorinated dibenzodioxins and polychlorinated biphenyls, from exhaust gases from waste incineration plants by thermal treatment at temperatures between 300 DEG C and 700 DEG C in the presence of a catalyst containing iron oxide, where a) air and NH3 are added to the hot exhaust gases for the simultaneous reduction of the NOx fractions, and b) the catalyst used is a sulphate- and/or phosphate-containing iron oxide catalyst. The process according to the invention is characterised in that in step a) a reaction temperature of at least 400 DEG C is used and the amount of ammonia added is adjusted to be greater than the stoichiometrically required amount for the reduction or complete elimination of NOx fractions. The process according to the invention has the advantage that excess ammonia is completely combusted, so that exact stoichiometric metering and the associated controlling effort can be avoided. <IMAGE>
