Title: Dispositif et procédé pour la compensation en fréquence d'un amplificateur opérationnel.
Inventor: FREDERICK GILLIG STEVEN
IPC: H03F3/45
Filed: 1994-11-07
Abstract: Circuit de transimpédance (201) et son procédé associé pour la compensation en fréquence d'un amplificateur opérationnel, possédant une borne d'entrée (205) couplée pour recevoir un signal amplifié (205) et une borne de sortie (206) prévue pour produire un signal amplifié à tampon. La borne d'entrée (205) du circuit de transimpédance (201) présente une impédance d'entrée résistive au signal amplifié à une fréquence proche d'une fréquence de gain unitaire de boucle ouverte de l'amplificateur opérationnel (200). Le signal amplifié passe dans un tampon d'une impédance complexe d'une borne d'entrée (206) d'un circuit d'attaque de sortie (103). La présente invention assure, de façon avantageuse, une grande largeur de bande et un fonctionnement stable avec des charges ayant une faible impédance complexe.

Title: Spring-loaded spectacle hinge
Inventor: JAFFELIN ETIENNE
IPC: G02C5/22
Filed: 1994-12-02
Abstract: The hinge includes a knuckle (1), connecting a lug (3) on the spectacle frame to a side piece (5). There is a spring strip (6) connecting the hinge pivot (4) to the side piece. The spring strip is designed to hold the side-piece in stable positions when open or folded, and returns it to its stable position if it should be moved too far outwards. The spring strip has a curved section, and it is attached to the hinge pivot by clips on one end, enabling the hinge to be dismantled without the aid of tools. In a variant of the design the spring strip can be replaced by a double rod.

Title: Locating process for ground-embedded container, e.g. tank
Inventor: BRILLAUD PHILIPPE
IPC: B65D88/76
Filed: 1994-12-08

The upper parts of the membrane, above the mass of earth, are then moved to cover the top of the earth mass, and joined to each other with connectors (7) to enclose the top of the container. The remaining volume of the ditch is then filled with earth to fully enclose the container and membrane.
Patent FR-2728075-A1 (FR)
Title: Impedance measuring device for impedances having length comparable to excitation wavelength
Inventor: EUMURIAN GREGOIRE
IPC: G01R27/04
Filed: 1994-12-09
Abstract: The impedance measuring device has a connector with known impedance characteristics formed by two rigid conductors (1,2) which can be displaced so the distance between them can be varied. The conductors are triangular in shape. The two conductors converge toward each other, and are pivoted one from the other at their apex (A). The impedance being measured connects between the ends of two triangles. The length of the triangles corresponds to a multiple of a half wavelength at the frequency of the signal carried by the line. Measurement of the angle between the two conductors and the impedance at the apex of the triangle allows the impedance between the two opposing sides of the triangle to be determined.

Title: Finned heat exchanger operating between first gaseous fluid and second flowing fluid
Inventor: MARTINS CARLOS
IPC: F28F1/28
Filed: 1994-12-22
Abstract: The heat exchanger comprises a stack of heat conducting thin fins (A1-i) having between them a series of gaps (6) of small thickness for the passage of the first fluid. The fins are in thermal contact with the second fluid which flows through  channels (5) passing through the fins and extending in the direction of the stack. Each channel is formed by brazing and sealing the truncated annular edges (1) of holes (2) passing through the fins. One (A1) of the two end fins of the stack constitutes a wall of a manifold (A1,S1) through which the second fluid penetrates into the exchanger. The manifold communicates with the ducts through holes passing through the end web. One of the two end fins is joined to a supplementary pressed plate (S2) which is locally separated from the end fin to form depressions (7). Each depression communicates with the holes passing through the end fin so as to form, with the corresponding channels, a U trajectory for the second fluid.
Patent FR-2729015-A1 (FR)
Inventor: LAVIEVILLE JEAN PAUL
IPC: H02M3/07
Filed: 1994-12-29
Abstract: The multilevel convertor includes a voltage source (SE), a current source (C) and a succession of controlled switching cells (CL1,CL2...,CLn) each having switch pairs (T1,T`1,T2,T`2...,Tn,T`n) controlling the switching of capacitors (C1,C2...,Cn). The capacitors have nominally charge voltages proportional to their row in the convertor. The convertor has in parallel with the current source (C), a RLC filter circuit (CF). The filter circuit is designed to preferentially dissipate, at least in part, the energy of any component having a frequency included in a frequency band extending from the fundamental frequency of the voltage applied to the current source to a frequency equal to n times the convertor frequency, called the decoupling frequency, n is the number of convertor stages. These two frequencies, fundamental and decoupling, are not included in the frequency band.

Title: Converting natural light into light with planar polarisation in video image projectors
Inventor: SUKHANOV VITALY IVANOVITCH
IPC: G02B5/30
Filed: 1996-10-08
Abstract: The converter includes a source (1) natural white light and a divider (3). The divider splits the beam into a reflected beam and a transmitted beam. The two beams consist of either s- or p-polarised light. The two planes of polarisation are orthogonal with respect to one another. A rotator (6) turns the plane of polarisation of one beam parallel to the other. A device combines the two emerging beams with the same polarisation. The beam divider is a stack of parallel plates of two distinct optical media which alternate with refractive index (nl,nm). The thickness of each plate is much greater than the wavelengths of coherence of the light coming from the source. The angle of incidence (theta) of the beam on the second plate (102) is eta  /> eta b = arctg(nl/nm).  eta b is the Brewster angle of incidence on the second plate (102) made up of material with second index.

The flap comprises contacting layers of polyethylene terephthalate, the first is weldable, the second, intermediate layer can be ruptured. A further top layer is made of polyethylene. Thermal welding is applied around the perimeter of the cup and on the tab, on both sides of the precut line.  Also claimed is the sealed package as described. The final form is completed by cutting out or stamping along the welding line. Vacuum is applied, and a protective gas (e.g. nitrogen and carbon dioxide) is injected.
