  • Patent number: 4752122
    Abstract: An apodizing filter is disclosed comprising two solid bodies of transparent material the first of which is struck by the incident light while the second receives the light from the first. The second body has a curve surface approaching the first body at a distance therefrom not greater than some wavelengths of the incident light. The plane tangent to the curve surface of the second body at the point of minimum distance from the first one forms with the direction of the incident light an angle greater than the limit angle of the total reflection related to the first body with respect to the medium in which the filter is sunk. The indexes of refraction of the two materials of which the two bodies are made are such that the light incidence on said tangent plane is lower than the limit angle of the total reflection. The combination is disclosed of the apoditic filter according to this invention with a mirror and an example is given of the filter application to a laser cavity.

  • Patent number: 4752958
    Abstract: The device obtains several characteristic parameters from a standard sentence said by a speaker and compares them with average parameters of the same speaker stored in an internal memory and previously calculated. According to the comparison, it obtains a probability value that the sentence spoken belongs to that speaker and compares the value with a threshold normalized to the average parameter variance by a threshold calculation circuit. If the threshold is overcome, the device considers the speaker verified. A circuit determines the real instants of sentence beginning and end using a noise-adaptive threshold in order to limit between these two instants the time interval over which characteristic parameters are to be calculated. A circuit aligns as to time the characteristic parameters just calculated to the parameters of a reference sentence, obtaining standard lengths of the sounds composing the sentence spoken.

  • Patent number: 4751132
    Abstract: A process is provided for preparing an elastic film of a specific elastomeric composition which is formed by melt blending two particular elastomers, each of which is composed of hard and soft segments made from poly(tetramethylene ether)glycol, 1,4-butane diol and a phenylene dicarboxylic acid or a derivative thereof. One of the elastomers has an inorganic anti-blocking agent compounded in it. The process includes the steps of melt blending, melt extrusion, quenching and providing a draw-down of 12 to 40 to form a film which is particularly suited for use as elastic leg-strips in diapers.

  • Patent number: 4749368
    Abstract: A contact strip for the electrical connection of at least one flat conductor of a flexible conductor film, which contact strip comprises a strip-type base part of electrically conducting material and at least one group of teeth projecting outwards from a surface of the base part, for cutting through the flexible conductor film and contacting the conductor while the teeth can be deformed in the direction of the base part to press the base part. According to the present invention the base part comprises at least a second group of teeth projecting outwards from the surface of the base part, in which the first and second group of teeth are positioned within the periphery of the strip-type base part. All teeth of a group are arranged in a closed peripheral line such as circle, ellipse, triangle, square or other geometrical polygon and the distance between these teeth is smaller than the smallest dimension of the flat conductor to be contacted.
