  • Patent number: 10773193
    Abstract: A filter element is provided with a filter medium and a first end disk connected to the filter medium. A first bayonet protrusion is disposed on the first end disk and designed to engage behind a first bayonet receptacle of a filter housing of a filter. The first bayonet protrusion has a free end. The first bayonet protrusion projects at least over sections thereof in a radial direction relative to a filter element longitudinal axis of the filter element past the filter medium. The free end projects in the radial direction toward the filter element longitudinal axis. A filter with a filter housing provided with a first bayonet receptacle is provided and the filter element is arranged in the filter housing such that the first bayonet protrusion on the first end disk engages behind the first bayonet receptacle of the filter housing.

  • Publication number: 20200263637
    Abstract: An electromagnetic positioning device having anchor means which are realized for actuating a positioning partner and which are movable in an anchor space relative to stationary core means (30), which conduct magnetic flux, as a reaction to an energization of stationary coil means (32), the coil means, which have a coil support (32) provided with a winding and at least one external contactable connector (46), being embedded at least in sections in the core means and/or being surrounded by said core means and the core means realizing an end surface (34), which is planar at least in sections, for interacting with the anchor means, wherein the core means and the coil means are embedded in and/or surrounded by a one-piece pot-like and/or cup-like housing (38) made of a material suitable for deep-drawing in such a manner that the core means rest on a membrane-like, continuous and closed base section of the housing, the base section realizing a boundary surface of the anchor space.

  • Patent number: 10744433
    Abstract: A filter element for a fuel filter has first and second end plates and a particle filter medium arranged between the first and second end plates. A bayonet protrusion on the first end plate is designed to engage a bayonet receptacle of the filter housing by rotation of the filter element about a filter element longitudinal axis. An internal sealing element on the second end plate is designed to separate a raw side from a water collecting chamber of the fuel filter. The filter housing has a filter housing body and a cover screwed onto the filter housing body. The filter housing has a bayonet receptacle arranged on its inner side. By rotating the filter element about a filter element longitudinal axis of the filter element, the bayonet protrusion engages the bayonet receptacle of the filter housing when the cover is unscrewed from the filter housing body.

  • Patent number: 7574190
    Abstract: The present invention relates to a method and an electronic circuit for processing at least two at least partially correlated output signal streams of a mixer, the mixer having at least two signal inputs and at least two electric signal outputs. In order to provide a method and a device or an electronic circuit which enables the correlated signal portions of the output signals of a mixer to be separated from the uncorrelated signal portions undelayed, it is proposed according to the invention that the difference of the output signal streams of the mixer is formed pairwise directly and during the readout of the signal streams and that the circuit has an apparatus for the instantaneous formation of the difference between the signal streams of two mixer outputs in each case.

  • Patent number: 7361883
    Abstract: The present invention relates to a photonic mixer device with a photosensitive layer, at least two modulation gates (3, 4, 103, 104, 203, 204, 303, 304, 403, 404) and at least two readout electrodes (1, 2, 101, 102, 201, 202, 301, 302, 401, 402, 501, 502, 601, 602) connected to the photosensitive layer, the modulation gates (3, 4, 103, 104, 203, 204, 303, 304, 403, 404) being able to be connected to a modulation device which raises and lowers the potential of the modulation gates relative to one another and relative to the preferably constant potential of the readout electrodes corresponding to a desired modulation function.

  • Publication number: 20050237593
    Abstract: The present invention relates to an electromagnetic mixing system for receiving and processing modulated electromagnetic signals, with a signal detector made from a semiconductor material for receiving and converting electromagnetic radiation into an electric measured value and with at least one modulation input modulating the reception of the signal detector, and also with at least two accumulation electrodes which are connected to output electronics at the output of which a mixture of the received signal and at least one modulation signal applied at the modulation input is effectively provided as electric signal. The present invention also relates to a method for operating such an electromagnetic mixing system, the electromagnetic signals striking the signal detector producing charge carriers which, depending on the at least one modulation signal, are conducted at least partially alternately to the at least two different readout electrodes.
