Abstract: An improved cap for underdrains in gravity filters has a top surface (12) and a bottom surface (14) with a plurality of tapered screen members (20) defining slots (22) in the top surface. The slots provide communication with the filter bed without passage of fine grain filter media therethrough. The screen members are inclined with respect to horizontal to define a plurality of raised portions in the top surface, each raised portion defining a distribution chamber (26) above the orifices in the distributor. The cap (10) may be included in a capped filter underdrain block having a plurality of ribs and orifices on a top wall of the block. The cap rests on the ribs and cooperates with them to define distribution chambers above the orifices in the top wall of the block. The distribution chambers promote intermixing of air and water prior to introduction to the bed, and the ribs (36) finely meter backwash fluids for even distribution of backwash fluids throughout the entire filter bed.

Abstract: A double walled drum (10) of concentric cylinders (12,14) having end seals and insulation (16) between the cylinders (12,14). The drum (10) is open at both ends and rotates on its center longitudinal axis which is pitched from the horizontal with the entrance on the high side. Diameter restrictions at the entrance (26) and discharge ends (28) of the drum increase product residence time. Lifters (30,34) at the entrance (26) end discharge (28) end push flexible strandular food subject to microbial spoilage such as strands of cooked pasta away from the entrance and out the discharge. Pins (32) are mounted perpendicular to the inner cylinder wall and point to the central axis of the drum. Liquids such as acid and oil are sprayed onto the food in the drum from a spray bar (42) or spray manifold. The pins (32) continuously lift and separate the strands of food while it moves through the drum (10), and mix the liquid and product, resulting in a uniform coating. 
     This process and apparatus produce a uniformly coated flexible strandular food such as spaghetti with minimal temperature loss. The food is free flowing and not tangled at the discharge of the drum (28). Surges from upstream equipment are suppressed, producing a uniform flow to downstream equipment.

Abstract: L'invention concerne un dispositif pour traiter les eaux ou les boues de rejet au moyen d'échangeurs ioniques tenus sur des supports, comprenant: un récipient; un moyen d'alimentation pour amener l'eau usée à traiter dans le récipient; un moyen d'alimentation en supports pour amener les supports portant des échangeurs d'ions dans le récipient; un moyen d'agitation agencé dans le récipient; et un dispositif de séparation relié au récipient au moyen d'une conduite pour séparer les supports de l'eau usée. Dans ce dispositif, les supports des échangeurs d'ions sont en suspension ou flottent dans l'eau, si bien que les risques de colmatage sont évités. Le système de séparation empêche les échangeurs d'ions d´être évacués en même temps que l'eau usée qui vient d'être purifiée. Ce système de séparation peut être constitué par un filtre, par exemple un filtre mécanique ou électrostatique, mais il peut également être formé par un dispositif de séparation magnétique. Naturellement, les supports doivent alors être magnétiques.

Abstract: Méthode permettant de donner des instructions avec efficacité et sûreté individuellement à chaque robot lorsque ces robots sont installés avec une forte densité. Une instruction d'alimentation manuelle étant introduite dans un régisseur B, les coordonnées de position instantanée des points caractéristiques Pi et Qj définies pour les robots A1 et A2 sont successivement simulées, mises à jour et mémorisées dans une mémoire à accès aléatoire. La distance R entre le point caractéristique Pi (i = 1 à la valeur finale) et le point caractéristique Qj (j = 1 à la valeur finale) est obtenue consécutivement. Chaque fois qu'une plus courte distance R entre les points caractéristiques est calculée, la valeur de cette distance est mise en mémoire dans un registre Rmin. Ainsi, la plus courte distance entre les robots A1 et A2 est calculée (étapes S1 à S12). En fonction de la plus courte distance Rmin, la vitesse d'alimentation manuelle effective V est accrue ou réduite (étapes S13 et S14).

Abstract: Um einen Twin-Bremskraftregler mit Steuerstößel und Waagebalken mittels einer elektromagnetischen Sperrvorrichtung an seiner Druckminderfunktion zu hindern, wird zur Vermeidung von hohen Kosten und großem Materialaufwand erfindungsgemäß vorgeschlagen, die elektrische Spule (18) samt Magnetanker (17) und daran befestigtem Sperrglied (16) radial zu den Regelkolben (3) anzuordnen und das Sperrglied (16) mit dem Steuerstößel (13) formschlüssig in Eingriff zu bringen. Vorzugsweise wird dazu am Sperrglied (16) eine U-förmige Gabel angebracht, deren innerer Durchmesser dem Steuerstößel angepaßt ist. Sinnvollerweise ist die ausgefahrene Stellung, also die den Steuerstößel (13) sperrende Stellung des Sperrgliedes (16) durch die Position des Magnetankers (17) bei stromdurchflossener Spule (18) definiert, während die zurückgezogene Stellung des Sperrgliedes (16), welche den Steuerstößel (13) freigibt, sich bei stromfreier Spule (18) durch zurückfahren des Magnetankers (17) ergibt. Dadurch eignet sich dieser Twin-Bremskraftregler zur Verwendung in blockiergeschützten Bremsanlagen, wobei die Druckminderfunktion solang ausgesetzt ist, wie die Blockierschutzfunktion ausgeübt werden kann, und erst dann in Kraft tritt, wenn die Blockierschutzfunktion außer Kraft gesetzt ist.

Abstract: A circuit[100] for shifting the bits of an X word to obtain a Y word which is rounded to the nearest odd integer if any bit having the value 1 was shifted off of the word during the shifting operation. The circuit avoids biasing in the integer rounding operation. The shifting operations are accomplished with the aid of multiplexing circuits[101-105]. The rounding operation is accomplished with the aid of multiplexing circuits[105] that connect the least significant bit of Y to (X₀ OR X₁ OR ...X m ), where m is the number of places by which X is shifted.

Abstract: The invention relates to the working with a ground compactor which is driven by an internal combustion engine. The object of the invention is to provide a process, capable of being implemented with simple means, which makes it possible to determine and indicate the degree of ground compacting attained instantaneously by the ground compactor during operation, and which yields very accurate results, particularly towards the end of a ground-compacting operation. This is achieved in that the ground compactor is driven by an internal combustion engine which, by an overspeed protection control loop which reduces the fuel delivery volume or temporarily blocks the fuel supply when a predetermined maximum speed is exceeded, is protected against exceeding the predetermined maximum speed value, and in that the extent of the reduction of the fuel delivery volume or the period of time and/or frequency of the blockages of the fuel supply in a time interval are determined and used to form an indicating quantity for the ground-compacting degree attained at each instant.
