Title: Resonant unity power factor converter
Inventor: PRINGLE DANIEL
IPC: H02M1/42
Filed: 1994-04-07
Abstract: The present invention is directed to a novel converter for interposition between an AC power source and a DC load capable of maintaining a substantially unity power factor independent of the impedance of the load. According to the invention, the converter has rectifying circuit means to provide DC power to a DC power output circuit from an AC source, means for varying the impedance seen by the AC source in the DC output circuit, and means responsive to a shift in AC input current away from an in-phase relation with the voltage of the AC source under loading of the DC power output circuit for controlling said impedance varying means in a direction to return the AC current towards in-phase relation with the AC voltage. More particularly, according to the preferred form of the invention, the means for varying the impedance seen by the AC source in the DC output circuit includes a resonant circuit interposed between the rectifying circuit means and the DC output circuit and connected to deliver DC power thereto. The converter includes a control circuit responsive to the DC voltage of the DC output circuit and the phase between the AC voltage and AC current. The control converter also includes a variable impedance responsive to the resonant circuit current for controlling the phase angle between the resonant circuit current and voltage across the resonant circuit.

Abstract: A process for coating printed circuit boards has the following steps: the face of the printed circuit boards to be coated is maintained at room temperature and if required is heated up to about 120 DEG C; then , in a first step, a preferably photopolymerisable, fusible, low-molecular coating medium which is highly visquous to solid at room temperature and preferably has a mean molecular weight from 500 to 1500 and is about 10  mu m to 200  mu m thick, is applied on the surface(s) to be coated of the printed circuit board. In a second step, a second high-molecular photopolymerisable coating medium preferably having a mean molecular weight from 2,000 to 10,000 and 2  mu m to 20  mu m thick is applied on the first layer. The thus coated printed circuit boards are cooled down to room temperature and the double-layered photopolymerisable coating is exposed, developed and hardened, preferably in contact with a mask. A device for carrying out this process is also disclosed.

Abstract: An eddy current sensor for monitoring the metallization of apertures and narrow-gauge pipes comprises an axisymmetric body (1) elongated along the axis of symmetry, on the inner surface of which is mounted a coil in the form of a helical winding wound along the axis. The body (1) is hollow, the ratio of the outer cross section D to the inner cross section d being such that 1.4 < D/d < 1.6; this, together with the fact that the coil (3) is mounted on the inner surface of the body (1), gives the coil greater mechanical strength and helps to protect it from damage without increasing the cross-sectional dimensions of the sensor. The internal space of the body (1) can be filled with a magnetoconductive material. It is expedient to provide inside the casing a central shaft (8) with a tapering plug at the end (7). The sensor is modified if there is a holder (6). The process for producing the sensor involves forming the coil on a dielectric elastic core (2) and producing the body (1) in its flat developed form; the casing is given its desired final shape after the core (2) with the coil (3) has been mounted on the casing when still flat.

Abstract: A flux for effectively melt-decontaminating a zircaloy contaminated with a radioactive contaminant Pu₂O₃ is provided. The flux comprises a mixture of a metal flux of a metal (e.g. Ca or Mg) having a higher chemical activity than plutonium at a temperature above the melting point of the zircaloy with a halide flux of metallic compound (e.g. SnF₂, PbF₂, CoF₂, CsF₂) of a halogen element having a higher atomic number than fluorine and has a smaller absolute value of the standard free energy of formation than a fluorination product of plutonium (i.e. PuOF). The addition of the flux to a molten zircaloy causes plutonium contained in the melt to be converted, through a two-step reaction, to PuOF which can be then separated as slag.

Abstract: L'invention a pour objet un procédé de réception d'un signal utilisé dans un système de télécommunication numérique synchrone du type SDH ou SONET. Selon ledit procédé, l'interprétation du pointeur s'effectue lorsque le récepteur présente trois états principaux possibles, le récepteur passant d'un état principal à l'autre sous le contrôle d'un compteur d'évènements. Lesdits états principaux sont les suivants: état normal (NORM), abandon de l'état pointeur (LOP) et état d'alerte (AIS). Lesdits évènements constituent la réception d'un nouveau pointeur (nouv._point) indiquant une n ouvelle valeur de pointage. Ledit procédé consiste à compter le nombre de nouveaux pointeurs successifs et à faire passer le système de l'abandon de l'état de pointeur (LOP) à l'état normal (NORM) après réception du nouveau pointeur (nouv._point) pendant un nombre de fois successives prédéterminées. Afin d'améliorer le taux de récupération de la transmission des données, le comptage des nouveaux pointeurs (nouv._point) continue lors du passage de l'état normal (NORM) ou de l'état d'alerte (AIS) à l'abandon de l'état de pointeur (LOP) indépendamment du passage effectué.
