  • Patent number: 9036150
    Abstract: A scattered radiation fire detector having radiation sources of different wavelengths and a scattered radiation sensor, which are arranged and formed so that their optical axes are directed at a common centre of a scattering volume. A sensor unit is furthermore formed to register forward scattering I1(?1,fwd) of a first radiation source, forward scattering I2(?2,fwd) of a second radiation source and backward scattering I3(?1,bwd) of a further first radiation source, to calculate scattered radiation intensity quotients Q1=I1(?1,fwd)/I2(?2,fwd), Q2=I1(?1,fwd)/I3(?1,bwd) and Q3=I2(?2,fwd)/I3(?1,bwd) and to detect the existence of a fire situation using the scattered radiation intensity quotients.

  • Publication number: 20130135607
    Abstract: The invention relates in particular to a scattered radiation fire detector (1) having radiation sources (2, 3) of different wavelengths and a scattered radiation sensor (4), which are arranged and formed so that their optical axes (9, 10) are directed at a common centre of a scattering volume (5). A sensor unit is furthermore formed in order to register forward scattering I1(?1,fwd) of a first radiation source (2), forward scattering I2(?2,fwd) of a second radiation source (3) and backward scattering I3(?1,bwd) of a further first radiation source (2), to calculate scattered radiation intensity quotients Q1=I1(?1,fwd)/I2(?2,fwd), Q2=I1(?1,fwd)/I3(?1,bwd) and Q3=I2(?2,fwd)/I3(?1,bwd) and in order to use them for the decision regarding the existence of a fire situation.

  • Publication number: 20090005253
    Abstract: The invention relates to a novel double hybrid system and to the uses thereof. This system provides, in particular, a tool that enables the detection of the interruption of a protein-protein interaction. The developed system uses transcription interference as a mechanism for detecting a breaking up of interacting protein pairs. The developed double hybrid system can be applied to the screening of molecules enabling the detection of molecules breaking up a protein-protein interaction as well as enabling the identification of alleles lacking in the interaction of proteins involved in the protein-protein interactions.

  • Patent number: 7165984
    Abstract: An operating element having an end piece, which is arranged for connecting to a printed circuit board and a front plate. An operating lever is rotatably mounted on the end piece. The operating lever has at least one grip section and one on and/or off lever piece, which are at least partly made from a wear-resistant material. Such a design has the particular advantage that part of the operating element which performs an on and/or off lever action, the on and/or off lever piece, opposite the section of the operating element to manipulate, the handle, is at least partly made from a wear-resistant material. The complete unit is thus rendered significantly more robust without sacrificing ergonomics of the grip piece.

  • Patent number: 7130199
    Abstract: An operating element for engaging and extraction of a planar sub-assembly with an end-piece prepared for connection to the planar sub-assembly. An operating lever rotatably mounted on the end-piece has at least one grip section and a locking element which may be displaced, in particular shifted between at least two switch positions, whereby in a first switch position, the operating lever is held in a state with the planar sub-assembly in an engaged position and in a second switch position, the operating lever is released for extraction. The operating lever has at least one combined display/switching element.

  • Patent number: 6924430
    Abstract: An actuating element for inserting and removing a flat module by leverage, the element having an end piece designed to be connected to a flat module. An actuating lever, which is pivotally mounted on the end piece, has at least one grip section and a locking element, which can be displaced, particularly slid between two connection positions. In a first connection position, the actuating lever retains the flat module in its inserted state and in a second connection position, the actuating lever is released to remove the module by leverage. The actuating element has a connecting element, which is activated in the first connection position of the locking element, which can be displaced into a third connection position, in which the actuating lever is retained in the first position, corresponding to the inserted state of the flat module and in which the connecting element is disconnected.

  • Patent number: 4917618
    Abstract: A mounting system for mounting plug-in modules into a module carrier is disclosed. The system comprises a plug-in and pull-out fixture, the fixture having a lever which is connected to the modules by means of an endpiece. The lever is provided with a resilient self-locking detent hook which extends in the lever's locking position behind the corresponding projection of the slot in the end piece, the slot facing downwards towards the transverse bar of the module carrier. This system allows for the insertion & removal of the modules with reduced force compared to the prior art, as well as improved ergonomic handling of the modules.
