Inventor: KNOSALA PETER
IPC: B01J49/00
Filed: 1991-11-15
Abstract: In the process for the desalination of salt-containing aqueous solutions, a mixed-bed filter, with at least one upstream cation exchanger resin filter and at least one upstream anion exchanger resin filter, is used. The mixed-bed filter is operated as a working filter in the same way as the cation and anion exchanger resin filters. The regenerant solutions used for regenerating the ion exchanger resins of the mixed-bed filter are subsequently used for the regeneration of the ion exchanger resins of the upstream cation and anion exchanger resin filters. An apparatus suitable for carrying out this process has a device for simultaneously taking off the regenerant solutions used for regenerating the ion exchanger resins of the mixed-bed filter. In this device, two horizontally extending liquid discharge systems (1, 2) are arranged above and below the separation surface (4) between the ion exchanger resins (5, 6) separated by hydraulic means. Thus, the regenerant solution for the upper ion exchanger resin layer (5) and the regenerant solution for the lower ion exchanger resin (6) can be taken off separately through the upper liquid discharge system (1) and through the lower liquid discharge system (2) respectively. Between the two liquid discharge systems (1, 2), a horizontally extending liquid inlet system (3) is preferably provided. <IMAGE>

Abstract: Outil d'échantillonnage destiné à être immergé dans un puits afin d'y prélever des échantillons de pétrole, de gaz ou d'eau pendant le forage ou la fabrication de ces fluides. Ledit outil (1) comporte un élément tubulaire, creux et de préférence cylindrique possédant deux chambres (12, 14) séparées par un tuyau compressible (9), ainsi qu'un tuyau externe (2) présentant la forme d'un élément cylindrique afin qu'il puisse résister à la pression du gisement. Une unité (13), disposée à l'intérieur du tuyau externe (2), forme une chambre de stockage (12) étanche aux gaz pour les échantillons de gaz ou de liquide, ainsi qu'une chambre (14) pour un milieu de contre-pression. On forme la chambre (14) en serrant le tuyau (9) contre l'intérieur d'un profilé en forme de U (10). Lors de l'échantillonnage, le volume de la chambre (12) augmente et le volume de la chambre (14) diminue en fonction de l'augmentation du volume de la chambre (12). On obtient une séparation totale de l'échantillon de gaz ou de liquide du milieu de contre-pression en appliquant un tuyau souple (9) anti-diffusion, et l'échantion de gaz ou de liquide analysé est donc représentatif de l'échantillon de gaz ou de liquide prélevé dans le gisement.

Title: FORMATION OF TABULAR GRAINS IN SILVER HALIDE EMULSIONS UTILIZING HIGH pH DIGESTION.
Inventor: BUNTAINE JAMES RAYMOND
IPC: G03C1/07
Filed: 1990-12-06
Abstract: The invention is generally accomplished by providing a tabular silver halide emulsion formation process in which the pH is controlled to greater than 9 by the addition of an alkali base prior to digesting to form uniform nucleated silver bromide particles. In a particularly preferred process the emulsion is adjusted to a pH greater than 9 by the use of sodium hydroxide, digestion takes place in between 3 and 7 minutes, and the emulsion making is completed in less than 100 minutes without the use of ammonium hydroxide. The emulsions formed are suitable for x-ray films and produce the image tone required by radiologists.

Abstract: In a carbon thread, vapor phase growth carbon fiber (VGCF) are dispersedly contained in a carbon matrix. The carbon thread is produced by forming a thread-like element from a mixture of VGCF and carbonizable carbon-containing compound and then by heat-treating the thread-like element to effect carbonization thereon. The thread-like element may be formed either by melt-spinning or solution-spinning the mixture, or by impregnably adhering the mixture onto a thread of heat resisting fibers. The carbonized carbon thread thus obtained may be subjected to further heat treatment to graphitize the carbon thread.

Abstract: An endless power transmission chain-belt (13) is disclosed that is especially adapted for drivingly connecting the pulleys (2, 3) of a pulley transmission (1). The chain-belt (13) has a chain (10, 12) that is an assembly of a plurality of interleaved sets of links (16, 18, 20, 22). A pivot means (24) extends through the chains (10, 12) to lace and pivotally interconnect adjacent sets of links (16, 18, 20, 22) to provide an endless chain-belt (13). The sets of links (16, 18, 20, 22) of the chain (10, 12) are held together by the pivot means (24). A plurality of first load block (14, 34, 35) are connected to the chain-belt (13). The first load blocks (14, 34, 35) has at least one projection (15) that extends in a direction towards the chain (10, 12). The projection (15) engages adjacent pivot means (24) to secure the first load blocks (14, 34, 35) to the chain (10, 12). The first load blocks (14, 34, 35) extend substantially across the width of the chain (10, 12) and have a substantially flat first bearing surface (21, 41) that is positioned adjacent the links (16, 18, 20, 22). Each first load block (14, 34, 35) has lateral edges (26, 28) shaped to frictionally engage the pulleys (2, 3) of the pulley transmission (1). A plurality of second load blocks (14, 34, 35) are connected to the chain-belt (13). The second load blocks (14, 34, 35) have at least one projection (15) that extends in a direction towards the chain (10, 12). The second load blocks (14, 34, 35) have a second bearing surface (21, 41) that is positioned adjacent the links (16, 18, 20, 22). The second bearing surface (21, 41) is disposed at an angle with respect to the first bearing surface (21, 41) of the first load blocks (14, 34, 35). The second load blocks (14, 34, 35) are disposed at an angle with respect to said first load blocks (14, 34, 35) when the first (21, 41) and second (21, 41) bearing surface are in contact with the links (16, 18, 20, 22) and the noise producted by the chain-belt (13) during use is reduced.
