Abstract: Systems and methods which provide enhanced isolation for receivers using relatively simple and inexpensive modifications or additional circuitry at a receiving station. Embodiments augment a primary antenna of a receiving station with a correlated heterogeneous antenna element. Augmented antenna systems of embodiments provide an appreciable increase in front-to-back isolation with respect to desired signals received at a receiving station. Such augmented antenna systems are particularly useful in a high interference environment, such as an interference limited environment as may be experienced at the edge of two Single Frequency Networks (SFNs). For example, embodiments of an augmented antenna system may be utilized in situations in which positive carrier to noise ratio (C/N) conditions are present (e.g., more signal than noise is present in the desired signal and more signal than noise is present in the interfering signal).

Abstract: The invention concerns an installation for cryogenic cooling comprising: a main reservoir (1) for a two-phase cryogenic fluid wherein is immersed a superconductor device (4) to be cooled; an auxiliary reservoir (9); and a hydrostatic duct between the bases of the main and auxiliary reservoirs; the auxiliary reservoir being arranged relative to the main reservoir and being dimensioned so as to be able to receive at least a large part of the cryogenic fluid present in liquid form (2) in the main reservoir; restricting means (11) being incorporated in an output manifold (7a) connected to the main reservoir; thus, when the superconductor gets rapidly heated, cryogenic liquid from the main reservoir is delivered, by the vaporized cryogenic fluid pressure, into the auxiliary reservoir wherefrom it flows again by gravity towards the main reservoir when the pressure of the vaporized fluid decreases.

Abstract: The invention relates to novel benzopyran derivatives of formula I, to their method of production, to composition comprising the derivatives and use thereof.

Abstract: A pharmaceutical composition suitable for administration to human beings in the prevention or treatment of immunologic disorders includes: an immune complex of an antigen and a purified antibody specific thereto, the antigen being selected from a group consisting of antigens that cause pathogenic immunologic reactions in autoimmune disease and graft rejections, and the antigen and antibody being present in a ratio whereby the antibody blocks essentially all binding sites of the antigen; and a pharmacologically acceptable carrier or diluent. The invention also provides a method of administering the composition for treatment of autoimmune disease and treatment or prevention of graft rejections.

Abstract: A pharmaceutical composition suitable for administration to human beings for suppressing the production of factor VIII inhibitor includes:an immune complex of factor VIII antigen component and factor VIII inhibitor component, the components being present in a ratio such that the inhibitor blocks essentially all relevant binding sites of the antigen; anda pharmacologically acceptable carrier or diluent. The invention also provides a method of administering the compositions to suppress the production of inhibitor to factor VIII.

Abstract: A pharmaceutical composition comprises an immune complex of an allergen and a purified antibody specific thereto, the allergen being selected from a specific subclass of antigen which causes immediate hypersensitivity that is mediated by IgE antibody, and a pharmacologically acceptable carrier or diluent. The method of using the compositions in the treatment of immediate hypersensitivity to the allergen is also described.

Abstract: In the treatment of allergy, desensitization is effected by administering the allergen in admixture with an antibody thereto, the antibody being present in a molar excess. The antibody is preferably one raised in the patient.

Abstract: The invention provides a method for combatting and/or preventing allergic diseases which are caused by house-dust mites by treating said mites or places or areas which are afflicted or may be afflicted by said mites with an effective amount of natamycin.
