Abstract: The circuit measures the level of an electrical signal, possibly with reference to a reference voltage. It can, with advantage, be applied to amplifiers with automatic gain control. 
<??>The circuit measures the level of an input electrical signal (Ve) and consists of an input amplifier (1), biased by a bias voltage, receiving this input signal (Ve) and producing an output signal (Vs), followed by a detector (2), itself followed by an integrator (3) delivering an integration signal (Vi). These three units form a measurement channel, the said integration signal (Vi) being the sum of a signal with a level proportional to the level of the said input signal (Ve) and an offset signal. The measuring circuit also incorporates a generator (6) producing a reference voltage (Vr), a compensation module (4) receiving the reference voltage (Vr) and producing a compensation signal (Vc), and a differential measuring amplifier (5) receiving the integration and compensation signals and producing a measurement signal (Vm). The bias voltage is the reference voltage (Vr). The compensation module (4) comprises stages corresponding to the units in the measurement channel in order to pass on the reference voltage (Vr) in conditions similar in all respects to those of the measurement channel. This produces a correction signal having the same value as the offset signal, the correction signal being included in the compensation signal (Vc).

Abstract: The invention is to a spindle (1) for use in mounting a toilet paper roll thereon, and more particularly, for use in mounting a coil of toilet paper, without the core (5), on the spindle (1). The spindle has a flange (45-47) near its outer end that stops movement of the core (5) as the toilet paper roll is pushed onto the spindle (1) during mounting. Continued pushing of the roll onto the spindle (1) while the core (5) is stopped, strips the coil of paper off the core (5). The coil ends up on the spindle and the core is disposed of.

Abstract: Solid oxide compositions of the formula La1-xSrxCrO3- delta  have been found to exhibit surprisingly high specific activity as catalysts for oxidation and hydrogenation reactions. They may be used in particulate form or applied as films to the surfaces of refractory substrates.

Abstract: Un connecteur électrique (2) comporte des cavités (48) de réception de bornes, dans lesquelles sont logées des bornes (4). Chaque borne (4) comporte une extrémité de connexion (10, 12) et une extrémité (26) destinée à recevoir un conducteur (6). Les bornes possèdent des revêtements isolants (8) qui sont positionnés sur les extrémités de réception de conducteur (26).

Un guide d'onde optique (39) ayant une âme (47) comprenant au moins une structure de puits quantique (62, 64) est interposé entre des première et seconde régions de recouvrement (43, 45), de sorte qu'un faisceau optique (51) inséré dans la région d'âme (47) se propage latéralement (53) par rapport à un sens primaire du faisceau. Des contacts (41) sont ménagés sur la surface de la région de recouvrement supérieur (45) et servent de moyens d'application d'un champ électrique à l'âme du guide d'onde. Le champ électrique induit un changement dans l'indice de réfraction de la partie de la structure de puits quantique (62, 64) se trouvant dans le champ. Le changement dans l'indice de réfraction a pour fonction de confiner latéralement la propagation du faisceau optique à la région de l'âme (47) se trouvant dans le champ électrique, tout en maintenant une transmission à faible perte. La régulation de la propagation latérale d'un faisceau optique au moyen d'un champ électrique appliqué permet la réalisation d'une famille de dispositifs optiques à faibles pertes tels que des modulateurs et des commutateurs. Lesdits dispositifs peuvent être fabriqués indépendamment de leur orientation dans la structure cristalline dans la matière semi-conductrice.

Abstract: A radially adjustable anvil roll assembly is provided for use with a die cutting cylinder of a rotary die cutting press. The adjustable anvil roll assembly comprises a shaft mounted for selective and intermittent rotation on the press, and a pair of eccentrics provided on an intermediate portion of the shaft. A hollow cylindrical sleeve is mounted for free rotation on the shaft eccentrics. Rotating the shaft so that the maximum eccentricity of the eccentrics is directed toward the die cutting cylinder adjustably positions the cylindrical sleeve in its closest adjusted position toward the cylinder. Rotating the shaft 180 DEG  so that the maximum eccentricity of the eccentrics is directed away from the die cutting cylinder adjustably positions the cylindrical sleeve in a radially adjusted position furthest away from the die cutting cylinder. The shaft is selectively and incrementally rotated only when adjusting the relative position of the sleeve to the die cutting cylinder and does not rotate during cutting operations of the press.
