  • Patent number: 11867551
    Abstract: A signal transmitter for a fill level sensor, a conductor path arrangement is printed on a resistor arrangement. The resistor arrangement is located below a slideway and is accessible between conductor path sections for trimming of the resistor. The signal transmitter is of particularly compact configuration and can be produced at low cost.
    Type: Grant

  • Publication number: 20160258805
    Abstract: A fill level sensor for a fuel tank of a motor vehicle includes electrical structures that consist of different materials. Sliding contact track structures exposed to the fuel consist of a gold-containing paste. Conductor structures are protected by a cover from contact with the fuel and consist of an especially inexpensive material. The fill level sensor therefore is highly resistant to corrosive fuels and can be produced at low cost.

  • Patent number: 9371643
    Abstract: A building facade consisting of a building wall, an insulating layer comprising insulating elements, having a surface and disposed on the building wall, a facade cladding which is disposed at a distance from the building wall and from the insulating layer to form a rearventilation gap between insulating layer and facade cladding and a lock element provided for fire protection, which is disposed between neighboring insulating elements of the insulating layer. In order to further develop a building facade in such a manner that it can be manufactured simply and therefore cost-effectively without additional structural elements being provided, the invention proposes a generic building facade where the lock element is formed in one piece from fiber material, extends over the surface of the insulating layer in the direction of the facade cladding and exhibits a compressibility and/or flexibility aligned at least predominantly between building wall and facade cladding.

  • Patent number: 8230655
    Abstract: The invention relates to an under rafters insulation system for a steep roof, comprising at least two mutually parallel extending building elements (3) which are spaced from each other, and insulation elements (4), in particular mineral fiber insulation elements, are arranged in a space between the building elements (3). The building elements (3) are mountable to rafters (2) of the steep roof by means of holding elements (5). For further developing an under rafters insulation system of the described type to the effect that the insulation elements (4) are easily supported between the building elements (3) at least over a period of time in which the under rafters insulation system (1) is not yet completed with a final cover, it is proposed that the holding elements (5) additionally secure the insulation elements (4) against falling out of the space between the building elements (3).

  • Patent number: 4220944
    Abstract: A resistance transducer with a non-linear characteristic curve, which transmitter has a resistance track with a variable cross-section on an insulating carrier and a slider engaging on the resistance track. On the resistance track on the insulating carrier of a thick layer system at least one additional layer is applied by the same technology made of a conducting resistor substance, and shaped such that it forms a rib which extends in a direction of movement of the wiper, the rib tapering outwardly perpendicularly thereto, and the wiper transversely engages the rib to form an approximately point-like contact surface.
