Patent EP-0458872-A1 (EP)
Inventor: RITCHIE RICHARD RUBEN
IPC: E06B7/30
Filed: 1990-02-16
Abstract: Un ensemble de visualisation comprend un morceau de matériau transparent (1) à monter dans une porte. Une surface réfléchissante (23) est montée sur le côté extérieur du matériau transparent (1), de sorte qu'une personne se trouvant du côté intérieur de la porte puisse la voir, et puisse alors voir des objets se trouvant sur le sol à proximité du côté extérieur de ladite porte. Une barre s'étend horizontalement sur l'intérieur du matériau transparent afin de définir une limite entre une image vue dans la surface réfléchissante et une image vue à travers le matériau transparent seul. Un rabat (50) est monté pivotant sur le côté intérieur de la porte et comprend une fente de visualisation ainsi qu'une saillie (52) en angle située sensiblement au même niveau horizontal que ladite fente lorsque celle-ci se trouve dans sa position de repos, mais permet à l'utilisateur de voir par la fente lorsque ledit rabat pivote légèrement. On a prévu une plaque entre le matériau transparent et le rabat, laquelle définit une ouverture (42) de visualisation, dont l'aire est sensiblement inférieure à l'aire de surface du matériau transparent. Ces caractéristiques aident à voir unidirectionnellement à travers le matériau transparent. On décrit également des caractéristiques permettant de monter ledit dispositif dans une porte, de sorte que l'on ne puisse pas le retirer de l'extérieur de la porte.

Abstract: Measurements of rheology apparatuses can be improved with reference to accuracy and reproducibility by means of the described method of temperature measurement. The temperature of the test substance in the measuring gap (49) is determined from temperature measurements directly below the surface, facing the measuring gap (49), of the measuring element (41) and/or measuring beaker (46). The energy required for the temperature measurement is generated by solar cells (22/23.1), fed with cold light, on parts of the apparatus which are rigidly connected to the measuring element (41) and/or the measuring beaker (46) and are moved in sympathy; the signals generated by the temperature measurement are coupled out of the moving parts capacitively or optically. In this way, the movements of neither the measuring element (41) nor the measuring beaker (46) are disturbed, and the rheological measurement is not affected in any way. Oscillators controlled by temperature-dependent crystals, or temperature-dependent resistors are used for the temperature measurement. <IMAGE>

Abstract: Disclosed herein is a diamond synthesizing method comprising the steps of introducing a mixed gas of hydrocarbon gas and hydrogen gas into a reaction vessel (9) which is maintained under a pressure of 1 to 100 Torr and causing dc discharge across a cathode (1) and an anode (2), thereby depositing diamond on a substrate (3) which is placed on the cathode (2). A positive column of Ha > CH is produced with a high formation rate of atomic hydrogen for promoting decomposition of the hydrocarbon gas, and concentration of hydrocarbon is reduced while maintaining the condition. According to this method, it is possible to synthesize high-quality diamond, which hardly contains non-diamond carbon components such as amorphous carbon and graphite, at a film forming rate of about 1 µm/h.

IPC: B01D53/047
Filed: 1991-02-01
Abstract: An adsorption unit comprises a compressor (10), an adsorber (22, 24) and a storage vessel (34). The storage vessel (34) is provided with a pressure sensor (36) which shuts off compressor (10) when the pressure in the storage vessel (34) reaches a predetermined first pressure. The compressor (10) is not reactivated until the pressure in the storage vessel (34) has dropped to a predetermined second pressure which is typically at least 6 bar below the first pressure. Steps are taken to ensure that whenever the compressor (10) is working the purity of gas entering the storage vessel (34) is substantially constant. This may be achieved by, for example regulating a control valve (32) disposed between the adsorber (22, 24) and the storage vessel (34) in response to the purity of the product or the pressure in the storage vessel. Other methods include adjusting the cycle time of the adsorber or adjusting its depressurization time. Overall operating costs may be reduced by operating the adsorption unit at high efficiency whenever the compressor (10) is running.

Abstract: L'invention se rapporte à un procédé utilisant la conversion en polygones en vue de séparer des éléments graphique et des éléments texte, ce procédé étant composé de deux processus séquentiels. On utilise à cet effet d'abord une étape de conversion vectorielle des trames en contours pour convertir une projection en mode point numérisée en un groupe de polygones simple. On utilise ensuite un processus de classification des éléments pour extraire six caractéristiques spécifiquement définies de chacun des éléments individuels à base de polygones en vue de permettre la séparation des polygones graphique et des polygones texte. Les polygones graphique sont ensuite classés en quatre sous-classes. Les polygones texte sont groupés en chaînes de polygones (chaînes d'éléments texte). Chaque chaîne contient une séquence de polygones de contours de caractéres segmentés, qui est prête à être soumise à un algorythme de reconnaissance de caractères optique, pour permettre la conversion des polygones en caractères de code ASCII compréhensibles par l'ordinateur.
