Patent NO-173378-C (NO)
Inventor: AHLBORN GUENTER
IPC: B61F5/38
Filed: 1989-11-29
Abstract: The invention relates to the connection of two running gears with multiple axles to a group of running gears for railway vehicles with low-lying loading bridge (10), the running gears having at least two wheel sets (4) of small wheel base and a running gear frame, comprising side cheeks (1) and transverse beams (2) between two axles in each case, the wheel sets (4), being fixed in the running gear frame by means of axle bearings (3) and each running gear being connected to the loading bridge without king pins, merely by means of in each case a laminated bearing spring (6), lying longitudinally at the side in front of each side cheek (1), and a link suspension. The object of the invention was to combine running gears of the type mentioned at the beginning into groups of running gears and to arrange them underneath the vehicle frame or the loading bridge (10) in such a way that the exact turning angle of each running gear and of each group of running gears when travelling around a bend is ensured without enforcement and that an exact axle load balancing of the running gears of each group of running gears is ensured. This object is achieved by the running gears of each group of running gears being connected to one another by a connecting beam arranged in the longitudinal centre of the running gears and mounted on them in a jointed manner, the connecting beam (13) being arranged centrally with play between guide brackets (14) of the loading bridge (10). In this arrangement, the facing ends of each laminated bearing spring (6) of the running gears of each group of running gears are connected to each other via their links by a compensating lever, which is mounted on a bracket of the weighing bridge. <IMAGE>

Title: Method and system for displaying color on a computer output device using dithering techniques
Inventor: WEISE DAVID N
IPC: G09G5/02
Filed: 1991-05-21
Granted: 1996-04-23
Abstract: A method and system for generating a dither pattern for a specified color are provided. In a preferred embodiment, the system generates a dith-er pattern corresponding to a specified RGB value. Each RGB value in the set of active colors is defined as a point in a three dimensional coordinate system having a red, green and blue component. The coordinate system is logically divided into a set of non-overlapping, tetrahedral spaces with each vertex representing a solid color. One tetrahedal space is designated as a mappin tetrahedral space. The system maps the specified RGB value to the mapping tetrahedral space from an original tetrahedral space containing the specifed RGB value. The system then determines the four active colors whose corresponding RGB values are closest to the mapped RGB value. The system then determines the number of pels in the dither pattern to set to each determined active color based on the distance between the RGB va-lue corresponding to the determined active color and the mapped RGB va-lue. The system then maps the determined active colors to the original te-trahedral space. Finally, the system sets the pels in the dither pattern to the mapped active colors based on the determined number of pels for that color and a predefined base pattern to effect the generation of the dither pattern.

Title: Treating material for animal excretions and method of producing the same
Inventor: FUJIURA YOJI
IPC: A01K1/015
Filed: 1992-04-28
Granted: 2004-09-21
Abstract: The invention relates to a treating material for animal excretions comprising agglomerates of a powdery or short-fiber-like excretion treating base material and fine powder of water-absorbent resin sprinkled on the agglomerates, and also to a method of producing a treating material for animal excretions which comprises forming agglomerates from a powdery or short-fiber-like excretion base treating material using water and then, sprinkling fine powder of a water-absorbent resin on the agglomerates. The treating material for animal excretions according to the invention can quickly absorb moisture, and its surface is brought to a half dry condition soon after it absorbs urine. Thus, it is possible to prevent urine from being attached to the pet's fur and paw, and contaminating the room or the like. Further, by absorbing urine, the treating material becomes a rubber-like mass.      Thus, only its portion having absorbed urine can be easily taken out and disposed. It is thus useful for treating excretions of pots or like animals.

Abstract: A flow meter (14) including a variable area obstruction (44) which is mounted in a conduit. Inputs (22, 38) to a differential pressure transducer (26) are positioned in the conduit on opposite sides of the obstruction to measure fluid pressure differential across the obstruction. In one embodiment, a sleeve (35) is secured within the conduit thereof substantially separated from the conduit so as to prevent fluid condensation on the sleeve, and to create a dead end pocket (37) between the conduit and the sleeve for collecting liquids from the conduit and preventing them from contacting the obstruction. The variable area obstruction comprises an elastic membrane that includes first (46), second (48) and third (50) leaves which extend into the flow stream and are compliant to fluid flow so that an increase in the flow rate increases the deflection of the leaves and increases the through flow area through the obstruction.
