Patent EP-0026085-A1 (EP)
Inventor: BRAINE MICHAEL RODNEY
IPC: H04B7/00
Filed: 1980-09-17
Abstract: In a satellite communication system a ground station transmits an information carrying plane polarised signal to the satellite where it is broadcast to a number of individual receivers on the earth. The effect of the earth's atmosphere partially de-polarises the plane polarised signal and to provide compensation for this effect, the earth station transmits simultaneously with the information carrying signal an additional plane polarised signal, which is polarised at right angles to the first signal so as to provide forward correction for the de-polarising effect. The additional signal is arranged to cancel the cross-polar components of the de-polarised signal produced within the atmosphere. A number of methods are described for determining the properties of the additional signal which are necessary to achieve compensation.

Abstract: The die-cast pieces are cast in a mold shell (4, 5) of a metallic material having a high heat conductivity. A refrigerating chamber (8) is connected to the shell. A refrigerating agent cools down the shell to the temperature of withdrawing from the mold. The refrigerating agent can be preheated and compressed to a pressure greater than the air pressure and during the cooling it can be vaporized. In order to obtain the greatest freedom in the choice of the solidification direction, the melted metal is supplied from a cavity avoiding a heating of the mold and the thinwalled shell of the mold is heated by the metal at a temperature close to the temperature of withdrawing from the mold. In the cooling phase during the filling of the mold, the vaporization of the liquid refrigerating agent takes place on the outer walls of the thin-walled shell.

Abstract: Procédé permettant de revêtir la surface d'un substrat en verre chauffé (16) avec un film d'oxyde métallique. Le substrat en verre se déplace dans une direction sélectionnée d'un procédé de fabrication de verre (20) et possède une température de l'ordre de 700 à 1200oF (370-650oC). Le procédé est réalisé en vaporisant un sel d'un métal de base organique, décomposable sur le ruban de verre. La poudre vaporisée est amenée à l'aide d'un courant gazeux sur une zone espacée au-dessus du substrat mobile. La poudre atomisée est ensuite accélérée depuis cette zone espacée au-dessus du substrat de verre mobile. L'accélération s'effectue en entraînant la poudre atomisée dans un courant d'air de haute vitesse. La poudre atomisée accélérée est dirigée vers le bas vers le substrat de verre mobile et longitudinalement dans le sens choisi de déplacement du substrat de verre. Des particules individuelles de l'atomisation sont soit vaporisées, décomposées et réagissent avec l'oxygène pour former un revêtement adhérant fortement sur le substrat de verre, soit elles sont rapidement refoulées.
