Patent EP-0017528-A1 (EP)
Inventor: HARENG MICHEL
IPC: G02F1/01
Filed: 1980-03-14
Abstract: The device of the invention breaks down the light (R1) into two polarised light vibrations, the ordinary (Ro) and extraordinary (Re), by means of a birefringent prism (Ni1). These two vibrations then traverse two liquid crystal cells (NH1, NH2) of nematic type in a helix with positive dielectric anisotropy. In the absence of a voltage (Vs) applied to the cells, the two vibrations have their directions of polarisation rotated through an angle ( theta ) of  pi /2 radians, while they are transmitted without rotation of the polarisation for a given voltage Vs, which is dependent upon the type of liquid crystal employed. Each cell is followed by a linear polariser (PO1, PO2), the two directions of polarisation of which are orthogonal in relation to one another. A second birefringent prism (Ni2) combines the two vibrations into a single non-polarised emergent vibration (R2). Application, in particular, to ultrasensitive television cameras. <IMAGE>

Abstract: A steel refining system has a crucible having an upwardly open mouth and containing a steel melt covered by slag, an oxygen lance directed downwardly into the mouth at the melt, a hood fitting downwardly over the mouth and having a hood wall formed by a multiplicity of coolant tubes, and an arrangement for circulating a coolant through these tubes. The tubes form a tubular hood-wall extension that has an outer end and is centered on an axis trained on the melt on the crucible. A holder is mounted on the outer end of this extension and contains a sound transducer carried by the holder and directed along the axis at the melt. A circuit is connected to this transducer for determining slag thickness by means of the sound detected by the transducer. The holder itself comprises a circularly annular hollow cell fixed by means of a collar to the extension and a transducer housing that is fixed to this cell and therethrough to the extension. The cell defines a passage aligned with the axis and is connected to a separate coolant circuit to prevent overheating of the transducer.

Abstract: Les matieres lamifiees en fibres de verre creuses souffrent encore aujourd'hui du defaut de contenir de l'eau et d'autres substances. Les procedes d'etanchement utilises jusqu'ici presentent encore des defauts qui sont elimines par l'invention. La fibre de verre creuse recoit des parois d'etancheite pendant l'operation de filage qui se deroule avec un gaz de protection constitue par un aerosol dans lequel la matiere de la paroi etanche est en suspension. Pour cela, on utilise surtout de petites billes creuses en verre, dont le diametre correspond a celui des fibres. L'aerosol est dirige par une canule refroidie, de diametre interieur de la fibre creuse, de facon que la vitesse du courant corresponde approximativement a la vitesse de filage (env. 1 a 1,5 m/s).

IPC: H01L39/22
Filed: 1981-12-09
Abstract: An amplifying or switching superconductive device is described whose current-voltage characteristic is drastically altered by heavy injection of excess energetic quasi-particles. In this device, the superconducting bandgap of a superconducting layer is greatly altered by overinjection of energetic quasi-particles so that the bandgap changes greatly with respect to its thermal equilibrium value, and in most cases is made to vanish. In a preferred embodiment, a three electrode (S I , S 2 , S 3 ) device is fabricated where at least one of the electrodes (S 2 ) is a superconductor. Tunnel barriers (32, 34) are located between the electrodes. A first tunnel junction (S 1 , 32, S 2 ) is used to heavily inject energetic quasi-particles into the superconducting electrode (S 2 ) to change its superconducting bandgap drastically. In turn, this greatly modifies the current-voltage characteristics of the second tunnel junction (5 2 , 34, S 3 ). This device can be used to provide logic circuits, or as an amplifier, and has an output sufficiently large than it can drive other similar devices.
