Abstract: Des huiles lubrifiantes qui sont utilisées dans des moteurs à deux temps provoquent parfois une obstruction (gélification) dans les filtres à carburant. La gélification est particulièrement soutenue lorsqu'une composition contenant un métal alcalin ou un métal alcalino-terreux est présente dans l'huile lubrifiante ou le carburant. La présente invention résout ce problème particulier en introduisant un soluble d'hydrocarbure ou un acide polycarboxylique dispersible dans le mélange de carburant et d'huile.

Abstract: Unité de détachage (48) adaptée pour être montée dans une relation d'écoulement en série avec un pistolet à carburant (42). L'unité de désaccouplement (48) comprend une partie flexible (50) assurant une transmission axiale de forces vers une partie de vanne (52), laquelle est séparée lorsqu'un véhicule quitte une unité de distribution avec le pistolet dans son réservoir de carburant. La partie de vanne comprend des coupures d'admission (62) et de sortie (64) ainsi que des moyens destinés à bloquer de manière détachable les coupleurs dans une relation assemblée. Ces moyens comprennent des doigts (112) fléchissant extérieurement lorsque une force de séparation dépasse une valeur prédéterminée. Des ressorts cylindriques en anneau (134, 136) entourent les doigts afin de commander avec précision à quel niveau les coupleurs se séparent. Les doigts viennent au contact de languettes (114) espacées de manière angulaire permettant audits doigts d'être télescopiques entre lesdites languettes et d'être ensuite tournés jusque dans une position de verrouillage afin de faciliter le réassemblage des coupleurs avec un minimum d'effort. D'autres modes de réalisation de l'invention décrivent d'autres formes de moyens de ressorts (537, 737) afin de réguler avec précision la force à laquelle les coupleurs se séparent. L'invention concerne également d'autres structures réduisant au minimum l'effort nécessaire au réassemblage.

IPC: D06B3/12
Filed: 1992-05-02
Abstract: In a wet-treatment installation for continuously running textile webs which works by double loop entry, interior upper and lower rollers are arranged, as is known per se, between exterior upper and lower rollers in the treatment compartments, so that the fabric follows a zig zag-shaped inner loop on its way from an exterior upper roller to the corresponding exterior lower roller. The interior upper and lower rollers have a smaller diameter than the exterior upper and lower rollers. Only the exterior lower rollers dip into the treatment fluid. According to the invention, a collecting and diverting plate (22) is arranged respectively between an exterior upper roller (18) and the associated interior upper roller (19). The excess treatment fluid adhering to the fabric web (26) is thereby guided in a controlled manner into the inner loop and therefore utilised more effectively than in known installations. The collecting and diverting plate (22) is mounted adjustably, so that it touches or does not touch the fabric web selectively. <IMAGE>

IPC: C02F3/30
Filed: 1992-11-16
Abstract: The invention relates to a method for the treatment of (raw) sewage in a package plant consisting of three bioreactors in series. The treatment is being carried out using three types of biomass. 
     In a first step (3,4) phosphate is removed by biological means and, at the same time, the chemical and biological oxygen demand is lowered in a highly loaded active sludge system, in a second step (10) a nitrification is carried out, ammonium being converted to nitrate, and in a third step a denitrification (12) is carried out using a carbon source. In the denitrification step acidified surplus sludge from the P-removing step can also be used instead of an external carbon source. The nitrifying and denitrifying bioreactors are both fixed film processes. The thickness of the biofilm on the support material in the nitrifying bioreactor can be influenced by adjusting the aeration system or by adjusting the hydraulic loading. In the denitrifying bioreactor the thickness of the biofilm can be adjusted by raising the shear by means of raising the superficial velocity in the support material. The system according to the invention makes possible effective treatment of raw sewage in a highly loaded system resulting in the far-reaching removal of COD, nitrogen and phosphate. 
     The process can be operated in an alternative mode, where the nitrifying and denitrifying bioreactors are exchanged; first bioreactor: biological-P-removal and simultaneous reduction of COD, second bioreactor: denitrification and third bioreactor: nitrification. The effluent of the nitrifying bioreactor is recirculated to the denitrifying bioreactor. 
     The first step is carried out in a plug flow bioreactor with an anaerobic and an aerobic zone. By using an intermediate settling tank (5) between the first and the second step, it is possible to discharge phosphate-rich surplus sludge. The mixing in the nitrifying step is advantageously maintained by aeration under the packages of support material. Mixing in the denitrifying step is accomplished by means of a propellor.

Abstract: To seal a pipe (1), a delivery tube (5) in the pipe (1) preferably through a side wall in the pipe (3) and a spraying means (7) is inserted through the delivery tube (5) into the pipe (1), using a flexible rod (9). The delivery tube (5) is more rigid than the rod (9) so that the delivery tube (5) prevents twisting of the rod (9) in the pipe (1). The spraying means (7) may then be moved along the pipe (1), by the rod (9) during the spraying of the sealant and the spraying means (7) may be adjustable, so that the sealant is sprayed e.g. in a preferred direction, typically upwards in the pipe (1). Alternatively the rod (9) with attached directional spray means, may be inserted directly into the pipe (1).

Abstract: While chelants such as ethylenediaminetetraacetic acid (EDTA) have been used for preventing scale deposition in boiler water, because of the expense it has not been used in cooling water treatment. It has been found that a relatively small quantity of a chelant can be used in combination with a scale deposit control agent such as a phosphonate to prevent scale deposition in cooling water. A preferred composition including a 4.5:1 ratio by weight of hydroxyethylene diphosphonic acid (HEDP) to EDTA displays a synergistic effect when used for scale prevention.
