Abstract: Abstract A fiber-optic polarizer comprising the combination of an optical fiber having a core and cladding with different refractive indices and forming a single-mode guiding region, the core having a non-circular cross-section defining two transverse orthogonal axes which, in combination with the different refractive indices, permit the de-coupling of waves polarized along the axes, the guiding region being located sufficiently close to the surface of the fiber, along a selected length of the fiber, to allow coupling to a contiguous medium, and the outer surface of the fiber having a non-circular cross-section with a predetermined geometric relationship to the guiding region and the orthogonal transverse axes so that the location of the guiding region and the orientation of the axes can be ascertained from the geometry of the outer surface.  A polymeric film extends longitudinally along a selected length of the fiber and is coupled to the fiber surface that is closest to the core, the film having different indices of refraction along axes aligned with the transverse orthogonal axes of the core, one of the indices of refraction of the film being less than the effective index of refraction of a desired wave in the guiding region of the fiber, and the other index of refraction of the film being greater than the effective index of refraction of an unwanted wave in the guiding region of the fiber.

Abstract: ABSTRACT OF THE DISCLOSURE     The present invention relates to a multi-stage wood chip cooking process performed in a single digester in a batch type operation.  The wood chips to be cooked are introduced into the digester and soaked with a warm black liquor to remove most of the air from the digester and the chips.  This warm black liquor is thereafter displaced from the digester with a mixture of a first stage hot black liquor and hot white liquor, the proportionate amount of hot white liquor being relatively high.  The temperature of the digester contents is then raised to a cooking temperature for a predetermined amount of time.  The original cooking liquor is then displaced with a mixture of a second hot black liquor and hot white liquor, the proportionate amount of hot white liquor in this second cooking liquor being less than in the first,  Again, the temperature of the digester is raised to a cooking temperature and the cooking is carried out for a shorter period of time than in the first cooking stage.  After the required number of cooks which may be preferably three but may be as low as two or more than three, the cooking liquor is displaced from the digester with a liquid filtrate derived from pulp washing.  Finally, the contents of the digester are  emptied by applying gas under pressure to the interior of the digester.

Abstract: ECHO CANCELLATION IN TWO-WIRE TRANSMISSION PATH REPEATERS          Abstract of the Disclosure A two-wire transmission path repeater includes, between two hybrid circuits coupled to the path, an echo canceller and an amplifier for each direction of transmission, each echo canceller including a transversal filter and a subtracting circuit.  The power ratio between signals before and after the subtracting circuit of each echo canceller is used to distinguish between simplex and duplex signals.  If the power ratio exceeds a given value, which is dependent upon the input signal power, for only one transmission direction then a simplex signal in the opposite direction is determined, the gain of the amplifier for the one transmission direction is reduced, and adaptation of the transversal filter coefficients for the opposite direction is prevented.  If the power ratio for both directions falls below the given value then a duplex signal is determined, the gain of both amplifiers is increased and adaptation of the coefficients of both transfer filters is continued for a short period, then the gain of both amplifiers is reduced and adaptation prevented, thereby facilitating stable operation of the repeater.
