Patent EP-0560240-A1 (EP)
Inventor: SAWA MASAHIKO
IPC: B01J29/04
Filed: 1993-03-06
Abstract: A process for producing aromatic hydrocarbons comprises bringing hydrocarbons having 2 to 12 carbon atoms into contact with a modified crystalline galloaluminosilicate catalyst prepared by treating a crystalline galloaluminosilicate having a mol ratio of SiO₂/(Ga₂O₃ + Al₂O₃) in the range from 5 to 1000 with a sulfur-containing substance. The process of the invention is simple and suited for general application and the catalyst can be prepared at a low cost. Aromatic hydrocarbons can be produced efficiently from the material hydrocarbons by bringing them into contact with the modified galloaluminosilicate having the excellent catalytic activity. The process of the invention can be adopted widely and effectively in the petroleum refining, in the petroleum chemistry and in the chemical industry in general.

Abstract: A microwave amplifier circuit has input and output coupling circuits (21 and 22) designed on quite different matching principles to obtain a circuit compactness similar to a reactively-matched amplifier and cascadable electrical characteristics similar to a distributed amplifier. The input coupling circuit (21) is formed as a bandpass filter network (7a, 7b, 7c, 17a, 17b, 9) supporting a travelling wave to which the amplifying device (3) is capactively connected. This input network (21) terminates in a resistor (9) in which the travelling wave is dissipated. The output coupling circuit (22) is a reactively matched circuit (8a, 8b, 18a, 18b) which also has a bandpass characteristic. By making the input network (21) bandpass (instead of low pass) a large amplifying device (3) can be used, without reducing line impedance and gain.

Abstract: The exothermicity attending decomposition of N₂O to nitrogen and oxygen can lead to a multiplicity of process difficulties associated with high process temperatures. The process of the invention solves three difficulties by cooling a portion of the exit gases depleted in N₂O from the decomposition zone and then recycling at least a portion of the resulting cooled gas stream to the N₂O-decomposition zone. The process is amenable to process control to afford a very stable process largely independent on the particular catalyst used for N₂O decomposition. Where the N₂O-containing waste gas stream also contains NO x , it is often highly desirable to pretreat the stream to remove NO x  prior to the N₂O-decomposition zone.

Abstract: Raster data are depleted to provide for faster printing with a printed dot size that is larger than would otherwise be utilized with the undepleted raster data, on a pixel grid having the resolution of the undepleted raster data. The data are depleted by
     (A) defining for all rows of the pixel data array a starting end such that the bits in each row are in a column sequence that starts at the starting end;   (B) sequentially selecting the second through last in sequence bit in each row, and setting the selected bit to 1 if the immediately adjacent prior in column sequence bit is a 1.   
     Raster data at a particular resultion (e.g. 300 dpi) are scaled up in such a manner that the upscaled raster data include only printed pixels that correspond one-to-one with the printed pixels of the original data and wherein the relative locations of the printed pixels of the original data are maintained in the up scaled raster data. A pixel array having a particular resolution caN be printed with a print element array having print elements disposed for printing at a lesser resolution.

Abstract: A device (10) for removing battery plates (3) from a stack (2) and for depositing the battery plates (3) on a conveying device has two grippers (30, 31) which are alternately effective. The grippers (30, 31) are moved alternately into a removal position detecting the first battery plate (3) in the stack (2) and into a delivery position, which is assigned to the conveying device. The grippers (30, 31) are mounted on levers (13, 14) mounted pivotably in the device. Each gripper (30, 31) is mounted on its lever (13, 14) in a manner which allows it to rotate through 360@ about a rotational axis (34) aligned in parallel to its swivelling axis (12), and is rotated in one direction by a drive (42, 40). In order to improve the detection of a battery plate (3), the grippers (30, 31) are idle relative to the lever (13, 14) carrying them if said levers are situated in their swivelling position corresponding to the removal position. Due to the fact that the grippers (30, 31) execute a rotary movement the rate of removal of battery plates (3) from the stack (2) may be increased without problem. <IMAGE>

Abstract: Dispositif et procédé de récupération des échantillons d'hydrocarbures de nouveaux puits, représentatifs du point de vue chimique. Le dispositif d'échantillonnage est pourvu d'une chambre d'échantillonnage chimiquement inerte et il est descendu à la profondeur requise dans le puits pour laisser entrer un échantillon de fluide du puits dans la chambre d'échantillonnage, laquelle est ensuite fermée hermétiquement. Le dispositif est de préférence agencé de manière que la pression à l'intérieur et la pression à l'extérieur de la chambre d'échantillonnage restent sensiblement identiques pendant et après le prélèvement de l'échantillon. L'échantillon peut être soumis à une pressurisation après l'échantillonnage pour conserver l'échantillon à son état originel de phase unique. L'inertie chimique de la chambre d'échantillonnage évite la perte de composants réactifs de l'échantillon de fluide du puits par réaction chimique avec le matériau de la chambre d'échantillonnage (qui est traditionnellement en métal). Ceci permet une évaluation précise des nouveaux puits, sans test d'écoulement prolongé. L'égalisation de la pression entre l'intérieur et l'extérieur de la chambre d'échantillonnage permet de choisir le matériau de la chambre d'échantillonnage pour son inertie chimique plutôt que pour sa résistance mécanique aux forces résultant du déséquilibre entre les pressions.

Abstract: An unloading valve adapted to open when a pressure difference between a discharge pressure and a maximum load pressure in a hydraulic pump exceeds a predetermined value and to make a flow quantity discharged from the hydraulic pump flow into a tank is connected to the hydraulic pump, a fixed throttle for producing control pressure corresponding to a flow quantity flowing out from the unloading valve is connected to the downstream side of the unloading valve, and a control device of the hydraulic pump is constructed such that, when the control pressure is high, the discharge flow rate of the hydraulic pump is decreased and, when the control pressure is low, the discharge flow rate is increased. Furthermore, in parallel to the unloading valve, and on the upstream side of the fixed throttle, a change-over valve is connected to the hydraulic pump, and this change-over valve is controlled such that, when the control input of a control lever is small, the opening area of the change-over valve is large, and, as the control input of the control lever is large, the opening area becomes small. With this arrangement, according to the control input of an operating means, either LS control by the unloading valve or bleed-off control by the change-over valve is performed selectively, so that a flow rate control utilizing the characteristics of the both controls can be performed.

Abstract: In a method of micropropagation, certified plants (1) received in tubes (2) are divided to provide nodal and apex cuttings (3, 4). These cuttings are planted in an agar gel (5) containing macro- and micro-nutrients in a tray (6), and enclosed in plastics sheeting (7) for growth under high photo photon flux and carbon dioxide enriched conditions to provide microplants. The microplants are divided to provide nodal and apex cuttings (8, 9), of which the apex cuttings (9) are replanted in a foam substrate (11) and again enclosed in gas and vapour permeable plastics sheeting (13) for further growth, again in a high photo photon flux and enriched carbon dioxide environment. Cyclic repetition of initially growth on agar and subsequently growth on substrate enable very substantial numbers of genetically consistent plants to be grown. In a final stage of the process, cuttings (16) taken from the growth arrays (14) which develop within the enclosures (13) are transferred for planting out in a substantially natural environment.
