Patent EP-0595803-A1 (EP)
Inventor: ROE DONALD CARROLL
IPC: B32B7/02
Filed: 1991-03-25
Abstract: Des macrostructures polymères absorbantes (52) et poreuses comprennent un agrégat réticulé interparticulaire ayant un volume à sec circonscrit de plus de 10,0 mm3. L'agrégat réticulé interparticulaire comprend une multiplicité de particules précurseurs d'un matériau polymère absorbant pratiquement insoluble dans l'eau et formant un hydrogel; et un agent de réticulation interparticulaire qui est amené à réagir avec le matériau polymère des particules précurseurs pour former des liaisons réticulées entre lesdites particules. En raison de la nature particulaire des particules précurseurs, la macrostructure (52) comporte des pores entre des particules précurseurs contiguës. Les pores sont reliés entre eux par des canaux qui communiquent entre eux de manière à ce que la macrostructure soit perméable aux liquides.

Abstract: Une unité de guidage et de montage (1) de ressorts de pression (16) comprend deux pièces de guidage et de montage (2, 3) pourvues chacune d'une section creuse de guidage (4, 5) et d'une section de montage (6, 7) à oeillet de raccordement (10, 11) et à bride de support (8, 9) agencés entre la section de guidage et la section de montage. Les deux pièces de guidage et montage sont axialement mobiles l'une par rapport à l'autre sur leurs sections de guidage. Afin de simplifier la construction en éliminant des composants additionnels, ce qui réduit le nombre d'opérations d'assemblage, ainsi que pour diminuer le poids de l'unité et rendre l'unité dans son ensemble plus facile à entreposer et à transporter, ava nt même son assemblage, les deux sections de guidage s'emboîtent télescopiquement et sont reliées de manière inséparable.

Title: Continuous rbcod measurement.
Inventor: BRIDGER JOHN STEPHEN
IPC: C02F3/00
Filed: 1991-07-03
Abstract: The invention provides a method and apparatus for providing periodical measurements of the real-time readily bio-degradable chemical oxygen demand (RBCOD) of a wastewater stream. The apparatus includes a bio-reactor (1) having an inlet (6) for accepting a continuous feed from the stream and an overflow outlet (7), whereby a sample volume can be maintained within the reactor. A feed rate is chosen to ensure an hydraulic retention time (HRT) in the reactor sufficient for substantially complete oxidation of the readily biodegradable compounds in the feed. Air (2) is periodically passed through the sample volume for set periods and the oxygen up-take (OUR) is determined by measuring the dissolved oxygen content via a probe (3) during the air-off periods. An RBCOD value is then calculated for each OUR value. The invention may be used to monitor the performance of wastewater treatment plants.

Abstract: L'invention décrit un procédé et un dispositif servant à déterminer la proportion d'un gaz paramagnétique dans un mélange de gaz. Elle comporte un élément capable d'osciller dans un champ magnétique. Une force s'exerçant sur l'élément à cause de la présence d'un gaz paramagnétique dans le champ magnétique, se modifie en fonction de la concentration du gaz paramagnétique présent. Cette modification de force affecte les paramètres de l'oscillation tels que l'amortissement et la fréquence, qu'on peut, de ce fait, contrôler pour déterminer la concentration du gaz paramagnétique.

Abstract: A process is disclosed of preparing a photographic emulsion containing tabular silver halide grains exhibiting a reduced degree of total grain dispersity. After forming a population of silver halide grain nuclei containing parallel twin planes, a portion of the silver halide grain nuclei are ripened out. The silver halide grain nuclei containing parallel twin planes remaining are then grown to form tabular silver halide grains. The total grain dispersity of the emulsion is reduced by incorporating bromide ion in the dispersing medium prior to forming the silver halide grain nuclei and, at the time parallel twin planes are formed in the silver halide grain nuclei, a grain dispersity reducing concentration of a polyalkylene oxide block copolymer surfactant is present comprised of two terminal lipophilic alkylene oxide block units linked by a hydrophilic alkylene oxide block unit accounting for at least 4 percent of the molecular weight of the copolymer.

Abstract: A data recording system for time-of-flight mass spectrometers is proposed which, at the same time, can be used as a control system for the time-of-flight mass spectrometer. This system defines for an adjustable number of mass passes a number of time intervals, which can also be adjusted, during which either the time-of-flight mass spectrometer is supplied with control signals or during which the ion intensity detected in a selected collector and adjustably amplified is integrated and added together for each time interval in a storage location allocated to the time interval. These storage locations are then read out by a separate computer after a preselectable number of mass passes and respective addition of the mass spectra. It is of importance that the time intervals for one mass pass are combined in a "time list" and various such "time lists" are allocated in arbitrary order to the mass passes occurring in succession. <IMAGE>

Abstract: A catalyzer control apparatus for purifying exhaust gas from an internal combustion engine has an electrically heated catalyzer (2) that is heated by a battery (15) which battery is isolated from the conventionally provided engine battery (4). The temperature of the catalyzer (2) is detected by a sensor (6) and a control circuit (12) located with an engine control unit (5) selectively applies power to heat the catalyzer (2). The catalyzer (2) is arranged to be pre-heated prior to engine start and by isolating the battery for heating the catalyzer from the normally provided engine battery so, because the catalyzer (2) takes a great power, engine starting is enhanced by virtue of having separate batteries (15, 4).
