Abstract: Antibodies directed against idiotypes on naturally occurring human anti-animal antibodies are disclosed for use in inhibiting xenograft rejection in human patients. An effective quantity of these anti-idiotypic antibodies is injected into the actual or potential xenograft recipient in order to bind to the idiotypes expressed on anti-animal antibodies as well as subpopulations of B lymphocytes, to inhibit hyperacute rejection of transplanted animal tissues or organs by the human patient. Alternatively, anti-idiotypic antibodies are used in the form of immunoaffinity columns to deplete anti-animal antibodies from the recipient's serum. Methods of making mouse monoclonal, mouse recombinant , and human recombinant anti-idiotypic antibodies are described as well as immunoaffinity columns containing immobilized anti-idiotypic antibodies. A method and means for assessing the expected character and severity of a patient's rejection response to transplanted animal tissues is described as well as methods of identification, isolation and suppression of lymphocytes bearing anti-animal idiotypes.

Abstract: A satellite receiver system (400) provides acquisition and frequency tracking of a Doppler-shifted radio signal received from an orbiting satellite.  The satellite receiver system (400) includes a Costas phase-lock loop (100) that receives the radio signal and provides an error signal at an error signal output (134) for controlling a conversion frequency generated by a voltage controlled oscillator (200). The voltage controlled oscillator (200) is coupled to the Costas phase-lock loop (100) and generates the conversion frequency for down-converting the radio signal in the Costas phase-lock loop (100). The satellite receiver system (400) further includes a Doppler frequency acquisition and tracking element (300) coupled to the voltage controlled oscillator (200). The Doppler frequency acquisition and tracking element (300) adjusts the conversion frequency to compensate for a Doppler frequency shift occuring in the radio signal due to orbital motion of the orbiting satellite.

Abstract: L'invention concerne un procédé permettant d'inhiber la formation d'hydrates clathrates dans un fluide contenant des constituants pouvant former des hydrates. Plus spécifiquement, le procédé peut être utilisé pour traiter un courant d'hydrocarbure tel que du gaz naturel transporté dans un tuyau, pour inhiber la formation d'un bouchon constitué d'hydrates dans ledit tuyau. Les inhibiteurs d'hydrates utilisés pour mettre en oeuvre le procédé sont des polymères pratiquement solubles dans l'eau formés à partir d'un iminoéther cyclique. De tels polymères peuvent être des polymères d'iminoéther cyclique à cycle ouvert, des polymères d'iminoéther cyclique à cycle fermé, ou bien des combinaisons de ces deux types de polymères. Parmi les exemples de polymères d'iminoéther cyclique à cycle ouvert l'on compte différentes N-acylpolyalkylénimines produites par polymérisation cationique, telles qu'une polyéthylénimine à substitution N-acyle, une polypropylénimine à substitution N-acyle, une polybutylénimine à substitution N-acyle, une polypentylénimine à substitution N-acyle, et des copolymères de celles-ci. Les polymères d'iminoéther cyclique à cycle ouvert peuvent être dérivés de la polymérisation par radicaux libres ou anioniques de 2-alcényl-2-oxazolines, 2-alcényl-2-oxazines, et d'autres iminoéthers cycliques possédant un groupe fonctionnel alcène. De tels polymères d'iminoéther cyclique à cycle fermé et à cycle ouvert peuvent être copolymérisés avec d'autres polymères pratiquement solubles dans l'eau ou bien utilisés dans diverses proportions avec d'autres polymères et copolymères pratiquement solubles dans l'eau. On utilise, de préférence, un solvant tel que de l'eau, de la saumure, de l'alcool, ou des mélanges de ceux-ci, pour produire une solution inhibitrice ou un mélange inhibiteur destinés à faciliter le traitement du courant d'hydrocarbure.
