  • Publication number: 20240133111
    Abstract: A microplastic filter (also referred herein as fluid filter) for a washing machine has a filter housing, a first filter screen, a second filter screen, an inlet opening 16, and an outlet opening. The inlet and outlet openings communicate with each other through the first filter screen to define a direction of fluid flow. The first filter chamber has a retentate outlet, is particularly easy to handle if the second filter screen is arranged in a cavity of the filter housing, the inlet and outlet openings communicate with each other through the second filter screen, and the retentate outlet is arranged on a side of the second filter screen that faces the fluid flow.

  • Publication number: 20230349419
    Abstract: A plain bearing includes an outer sliding surface element and an inner sliding surface element enclosed by the outer sliding surface element. The outer sliding surface element is divided along a substantially planar surface that includes the main axis of the sliding bearing and is formed with at least one radially encircling groove on the outer surface. A rubber-elastic or elastomeric is inserted in the at least one groove such that the ring holds together or retains the divided outer sliding surface element.

  • Patent number: 11174955
    Abstract: A diverter valve for conveying a material has a housing with at least three passage openings for feeding or discharging material. The passage openings define a conveying plane. The diverter valve includes a rotary part with an outer contour that is conical, at least in sections, with respect to its axis of rotation. The rotary part is arranged in a sealed manner in the housing. The rotary part can be axially displaced and rotated within the housing. The axis of rotation is perpendicular to the conveying plane. A passage conduit is arranged in the rotary part, which, depending on the rotational position of the rotary part, connects to each other two passage openings for conveying material along the passage conduit through the diverter valve. A drain opening is provided in the housing for the automatic drainage of a liquid from the housing.

  • Publication number: 20130277399
    Abstract: A cellular wheel sluice has a housing, a feed shaft opening therein and an outlet shaft opening out therefrom. Arranged between the shafts is a cellular wheel. The latter is arranged so as to be rotatably drivable about a horizontal rotational axis in a cylindrical cellular wheel housing portion. A cellular wheel drive shaft non-rotatably connected to the cellular wheel is rotatably mounted in the housing. A pressure drop is applied during operation of the cellular wheel sluice, a higher pressure being present in the feed shaft than in the outlet shaft. The cellular wheel is operated during the product conveyance between the feed shaft and the outlet shaft at a rotational speed in such a way that an outer periphery of the cellular wheel reaches a speed that is greater than 0.6 m/s.

  • Patent number: 8451100
    Abstract: Described is the use of a transponder in a commercial installation, particularly a power plant, which allows problems and dangerous situations existing in this context to be avoided and the attainable occupational safety in a commercial installation, particularly a power plant, to be increased. The transponder includes a reception element, a transmission element, a visual display unit and a memory element and also a control element which is operatively connected to these, in a commercial installation, particularly a power plant, in an arrangement or positioning on or in proximity to a component or at a switching or measuring point associated with the component for the purpose of visually displaying an operating state for the component or the switching or measuring point associated therewith using the visual display unit of the transponder.

  • Patent number: 8358686
    Abstract: A video compression system processes images captured from a video camera mounted to a vehicle. Vehicle-mounted sensors generate vehicle motion information corresponding to a current state of motion of the vehicle. An optical flow estimation circuit estimates apparent motion of objects within a visual field. A video encoder circuit in communication with the optical flow estimation circuit compresses the video data from the video camera based on the estimated apparent motion.

  • Patent number: 8160297
    Abstract: A system for processing an image of a surrounding of a vehicle is provided. The system includes an image generator that is configured for generating an image, the image having at least a first and a second portion. The first and second portions of the image differ from each other and the first portion of the image is generated for further processing earlier than the second portion of the image. Additionally, the system includes an image processor for processing the first and second portions of the image, where the image processor is configured for processing the first portion of said image while awaiting for the second portion of the image to become available to the image processor.

  • Publication number: 20090060273
    Abstract: In a system for evaluating an image, a processing device includes an input for receiving image data representing the image and another input for receiving distance information on a distance of an object relative to an image plane of the image. The distance information may be determined based on a three-dimensional image including depth information captured utilizing a 3D camera device. The processing device is configured for resampling at least a portion of the image data based both on the distance information and on a pre-determined reference distance to generate resampled image data, the portion of the image data to be resampled representing at least part of the object.

  • Patent number: 7285586
    Abstract: Coating compositions comprising a pigment and starch dispersion of discrete crosslinked starch particles in an aqueous liquid. The dispersion may be used as coating color for paper. A preferred process of preparing the dispersion of starch particles comprises (a) obtaining a mixture of starch and an aqueous liquid; (b) processing the mixture using shear forces in the presence of a crosslinker in an extruder; and (c) injecting a hydroxylic liquid into the extruder and dispersing the mixture inside the extruder or outside the extruder or both inside and outside the extruder to obtain the dispersion.

  • Patent number: 6705005
    Abstract: A method of forming a circuit board with electronic assemblies lying in different planes, includes providing a single circuit board with entire electronic assemblies pressed thereon. A channel is then formed in the circuit board of a predetermined depth to divide the circuit board into two separate, but integral portions. The circuit board is then bent at a point between the first and second portions of the circuit board such that the second portion of the circuit board can be bent between 0 and 180 degrees with respect to the first portion of the circuit board.
