Patent EP-0484582-A1 (EP)
Inventor: MANN RALPH DIPL-ING
IPC: F04D29/12
Filed: 1990-11-08
Abstract: Centrifugal pump, especially for pumping hot liquids, with at least one shaft passage to the outside through the pump housing and sealing of the shaft passage by means of a face seal (14, 15) and a scavenging and cooling flow for the face seal derived from the pumped medium. This flow is drawn from a higher pressure chamber, the pressure chamber (3), spiral chamber (6) or spiral side chamber (7) of the pump and led through at least one duct (8) provided in a housing cover (10) to an annular gap (13) formed between the housing cover (10) and an intermediate housing (11) inserted from the impeller wheel side into the housing cover, and from this close to the sealing face of the face seal (14, 15) into the seal chamber containing the face seal. After flowing through the seal chamber (16) the flow is fed via a choke gap to a low pressure chamber of the pump. In order to improve the scavenging and cooling effect it is proposed, according to the invention, that between the duct (8) and the annular gap (13) a distribution annulus be arranged, the width of which is a multiple of the annular gap (13) directed with radial direction components at the sealing face area of the face seal (14, 15) and that the pressure drop in the choke gap (17) be many times greater than the pressure drop from the higher pressure chamber (7) to the seal chamber (14).

Abstract: A manually operated fused switch contains housing contacts (3, 4) located in a housing (2). Arranged in the housing (2) in the manner of a drawer which cannot be removed is a switch slide (7) for holding a fuse insert (8), whose end contact caps (10, 11) make direct contact with the housing contacts (3, 4) in the switched-on position and which insert can be removed from the switch slide (7) in the switched-off position, outside the housing (2). A pivoting lever (18), which acts in drive terms on the switch slide (7) in the switching-off direction, is provided for rapid contact opening. Merely by pivoting said pivoting lever (18), the switch slide (7) is moved into a central contact-breaking position, in which the fuse insert (8) still lies inside the housing and is protected against being touched. <IMAGE>

Abstract: A composite cartridge-type filter effective to substantially reduce low but hazardous concentrations of lead in drinking water to acceptable levels utilizes a porous activated carbon block filter (11) and a powdered deionizing resin (25) which is converted to an ion exchange resin in situ and during use of the filter. The method of operation of the filter results in a substantially extended life for lead removal as compared to similar disposable cartridge filters. The composite filter is also effective in removing dissolved metals which are leached from the soluble ash fraction of the carbon block itself. Powdered deionizing resin, having a greatly enhanced active surface area as compared to the resin beads from which it is formed, is formed by fracturing the resin beads in situ in a slurry filling and drying process which provides a stable packed resin bed.

The shaft (38) is tapered and the screw flight (40) is correspondingly tapered so that the volume pumped by the screw along the length of the shaft remains substantially constant, or the rate of compression is substantially reduced, to provide consistent flow of material to the discharge opening and reduce build up of material against the front wall.

Abstract: The invention relates to an arrangement in a vehicle, for weighing a load placed on a tiltable platform, by raising this platform (8) in the main upward before the weighing, by locking the platform in its raised position, and by thereafter carrying out the loading onto the platform and/or the weigh­ing. The measuring signals for the weighing are obtained from three sensors (1a; 1b, 6, 2), of which two (1a, 1b) are fixed­ly installed on the platform pivot axle (12) in the chassis, at a distance (P) from each other, in such a manner that those portions (F1, F2) of the loading force which arrive via the platform pivot articulations (18) are transferred only via these force sensors (1a, 1b). The measuring point (6) of the third sensor (2) is located at a substantial distance (L) per­pendicular to the said distance (P) in such a manner that the remaining portion (F3; F4 + FS) of the loading force is trans­mitted through only this sensor. The other parts of the plat­form are, under the effect of the lifting, somewhat separated from the chassis structures (9).

Abstract: A printer including a platen-yoke apparatus. The platen (16) for e.g. wire matrix printer is mounted in a U-shaped channel (58). When the printer head (38) is moved to one side of a document feeding surface (12-1), a ramp (48) on one end of the platen (16) cooperates with a roller (46) secured to the print head (38) to depress that end of the platen to cause it to be moved below the feeding surface (12-1). A yoke member (22) rotatably secured to the underside (12-2) of the feeding surface (12-1) and coupled to the ends of the platen (16) causes the platen (16) to be moved parallel to the feeding surface (12-1) to lower the platen (16) below the feeding surface (12-1) to facilitate the insertion of a document (24) to a printing station (14) associated with the printer.

Abstract: Des circuits électroniques servent à commander les enroulements excitateurs de composants électromagnétiques pourvus de connexions à des circuits complémentaires, notamment des circuits en régime libre; de préférence, ces composants sont des soupapes magnétiques (MV1 à MVn) et sont connectés en série à un élément réglable de commutation (3), ce qui permet d'obtenir un réglage flexible. Afin de réduire la quantité de circuits, le coût de fabrication et le volume, les bornes (1, 4) de cette connexion en série mènent directement à un point collecteur (A, B, C); de même, les connexions (2) entre les composants (MV1 à MVn) et les éléments de réglage (3) mènent également à ces points collecteurs (A, B, C), par l'intermédiaire de diodes (D1 à Dn). Un seul circuit complémentaire (TF, CL, 10, 11) commun à tous les composants est connecté à ces points collecteurs. Les éléments du circuit complémentaire sont ainsi utilisés de façons multiples, étant donné qu'ils sont à disposition de tous les composants électromagnétiques.
