Abstract: A printed circuit board having conductor tracks formed on one side of a substrate. The substrate is able to be cohesively bonded at a contact face to a cover for protecting the conductor tracks. In this case, the substrate includes a step, which forms a barrier with respect to an auxiliary material for promoting the cohesive bond, in order to prevent any wetting of the conductor tracks with the auxiliary material. A sensor having a printed circuit board for use in a fuel filling level measurement system of a vehicle.

Abstract: A fuel delivery unit of a motor vehicle comprises a prefilter arranged inside a swirl pot, said prefilter having a filter element, and at least one connection piece for connecting a supplementary filter element. The at least one connection piece, in its initial condition, is closed, and is opened when the supplementary filter element is attached. The invention allows the fuel delivery unit to be adapted to projected filter surfaces of the prefilter.

Abstract: A device for collecting fuel in a fuel tank of a motor vehicle having a prefilter arranged inside a swirl pot. The prefilter has a section rising from a horizontal plane and a section lying in the horizontal plane. The sections of the prefilter are produced as one piece and are connected to the swirl pot. The prefilter has an especially large surface.

Abstract: A fuel delivery unit for a motor vehicle, wherein a swirl pot has a base formed from an upper part and a lower part, and an outer wall connected to the base, forming a seal. The upper part and the lower part bound fuel-delivering regions of a suction jet pump and of a section of a feed line. This arrangement allows the fuel delivery unit to be produced at particularly low cost.

Abstract: A delivery unit for delivering fuel in a fuel tank comprises a prefilter and swirl pot which are produced as one piece. The prefilter is produced during die-casting of the swirl pot. The invention allows the delivery unit to be produced in an especially inexpensive manner.

Abstract: A feed unit for feeding fuel has a housing formed integrally with the casing of a swirl pot, the housing comprising a fine filter. The fine filter is configured open toward one side and is closed by a cover. The cover is formed integrally with a base plate sealing the casing of the swirl pot. As a result, the feed unit has a particularly low number of components to be assembled and can be produced in a particularly cost-effective way.

Abstract: A feed unit has a surge chamber 1, a fuel pump 2, which is arranged in the surge chamber 1, and a pump holder 3, the fuel pump 2 being arranged in the pump holder 3 and the pump holder 3 being fastened in the surge chamber 1. The pump holder 3 has at least two rods 6 which are fastened in the surge chamber 1, the rods 6 being connected to a mount 5 for the fuel pump 2.

Abstract: In a feed unit for feeding fuel from a fuel container of a motor vehicle a surge part (1) has a base plate (9) and an adjoining tubular section (10). The base plate (9) is fabricated in one piece with a nozzle (15) and a mixer pipe (16) of a suction jet pump (8) and has receptacles (21, 13) for a fine filter (3) and for supporting rods (22) of a fuel pump (2). The feed unit is of particularly simple design as a result of this and can be fabricated in a cost-effective way.

Abstract: In the case of a fuel tank (1) for a motor vehicle having a plurality of surge chambers (6, 6?) for collecting fuel, two surge chambers (6, 6?) are closed in a manner essentially forming a seal and are connected to each other. Fuel conducted by a pressure regulator (12) and by suction jet pumps (16, 16?) into the surge chambers (6, 6?) is distributed to the surge chambers (6, 6?) as required. When the surge chambers (6, 6?) are completely filled, a pressure is produced, as a result of which a further filling by the suction jet pumps (16, 16?) is avoided.

Abstract: In the case of a fuel tank (1) for a motor vehicle having a plurality of surge chambers (6, 6′) for collecting fuel, two surge chambers (6, 6′) are closed in a manner essentially forming a seal and are connected to each other. Fuel conducted by a pressure regulator (12) and by suction jet pumps (16, 16′) into the surge chambers (6, 6′) is distributed to the surge chambers (6, 6′) as required. When the surge chambers (6, 6′) are completely filled, a pressure is produced, as a result of which a further filling by the suction jet pumps (16, 16′) is avoided.

Abstract: A plastic tank comprises a line which is connected at least in certain sections to its wall and is formed in one piece with the plastic tank. For its production, the plastic tank is injection-moulded between a hollow mould and an inner mould inserted into the latter, the mould having a recess, in which a sprue body is formed as the starting material for the line. Before this sprue body can solidify completely, material is blown out from it by means of the internal gas pressure or pressure blowing technique via channels provided in the mould, so that the required line is created there. The lines may be arranged on the outside and/or inside and parallel and/or at an angle to the tank walls.

Abstract: In the process for the agglomeration of slightly soluble and hydrolytically sensitive substances, a powder of the slightly soluble substance is conducted, together with at least one water-soluble binder, in free fall through a steam atmosphere at temperatures between 85.degree. C. and 105.degree. C. essentially without the action of compacting forces. In this process, the residence time in the steam atmosphere is approximately 0.5 to 10 seconds. The agglomerates formed are then dried in free fall, so that small solid bridges form from the binder liquid bridges formed at the points of contact between the primary particles. In a following integrated fluidized-bed dryer, the final drying then takes place to a water content of less than 0.5% by weight. The process is carried out in a steam jet agglomerator in which a freely falling product curtain of the pulverulent mixture to be agglomerated is impinged by steam using steam jet nozzles (5, 6).
