  • Publication number: 20060278220
    Abstract: A respirator shall be improved concerning better utilization of the carbon dioxide absorber (3). To accomplish the object, a transponder (5), which contains data on the type of absorber, the period of use and the current state of consumption, is arranged at the carbon dioxide absorber (3). A transponder polling device (8) at the respirator (1) reads the data from the memory chip (6) and an updated state of consumption is calculated from data on the operation of the respirator and stored again in the memory chip (6).

  • Patent number: 7098397
    Abstract: A junction box with a square housing and with at least opening and terminal strip for electric cables or lines. With the junction box, a housing arrangement can be modularly built from individual junction boxes that can be reliably connected to one another or to a base part. For attaching the junction box to a second junction box or to a base part, there are two pivotable locking elements on the housing which are movable from a first, open position into a second, locking position, and projecting ribs formed in the area of the outside corners on the housing, the locking element having a U-shape of which a U-bridge is used as an actuating clip and two U-legs, with ends which are bent down, and extend around the ribs on the housing of a second junction box or of the base part in the second, locking position.

  • Patent number: 7083463
    Abstract: An electrical supply or connecting terminal with a clamping spring and a metal part, the clamping spring having a clamping leg and a contact leg, and the metal part having a conductor bar piece. The clamping leg and the conductor bar piece form a spring force clamp connection for the electrical conductor. The contact leg of the clamping spring has a recess for insertion of the electrical conductor, and an end of the clamping leg extends through the recess. The clamping spring has a retaining section which runs essentially parallel to the insertion direction of the electrical conductor and parallel to the conductor bar piece and the conductor bar piece has been inserted though the recess in a direction opposite the insertion direction of the electrical conductor, the conductor bar piece being clamped securely between the end of the clamping leg and the retaining section.

  • Publication number: 20060086521
    Abstract: A housing arrangement with at least two junction boxes, a base part and a cover, the junction boxes each having a square housing with a terminal strip for electrical connection of an electric cable or a line, and at least two openings for electric cables or lines. The housing arrangement can be modularly built and variably adapted to different requirements since the individual junction boxes can be mounted on top of one another turned by 0°, 90°, 180° or 270° relative to one another. The terminal strips are connectors which can be mounted in a junction box in any of four positions which are turned by 90° relative to one another, and the connectors of two junction boxes which are mounted on top of one another can be connected to one another with the plug part of one connector can be inserted into the socket part of the other connector.

  • Patent number: 6737462
    Abstract: The invention relates to thermally stable, weather-resistant polyamide moulding compositions containing as stabiliser, a mixture of a copper halide, one or more halogen compounds and hypophosphorous acid or an alkali metal or alkaline earth metal salt of this acid, wherein the individual components of the stabiliser mixture are added in an amount such that the molar amount of halogen contained in the moulding composition is greater than or equal to six times the molar amount of and less than or equal to fifteen times the molar amount of copper contained in the moulding composition and the molar amount of phosphorus is greater than or equal to the molar amount of and less than or equal to ten times the molar amount of copper contained in the moulding composition.

  • Patent number: 6521832
    Abstract: A cable terminal or joint connection for making electrically conductive connection of a multi-core cable to an electrical device or to another multi-core cable, including a cable terminal component having a union nut and a wire receiving and guide part and including a device terminal component having a clamping and terminal unit which is provided with insulation piercing connecting devices and with terminal elements, and having a sleeve-shaped terminal body which is provided with an outside thread corresponding to the inside thread of the union nut. When the wire receiving and guide part is assembled with the union nut, the wire receiving and guide part is axially fixed via at least one slotted elastic locking ring in the union nut and the wire receiving and guide part is able to turn while in the axially fixed position relative to the union nut. Additionally, loss of the locking ring prior to assembly is prevented by fabricating the locking ring in one piece with the wire receiving and guide part.
