  • Patent number: 10435871
    Abstract: The present invention relates to a drinking and service water supply device (1) of a building with at least one circulation pipe (3) leading to at least one consumer (12) and with a regulating valve installed in the circulation pipe, and in a coordinated aspect to a regulating valve (18) for hot-water circulation systems, comprising a valve housing (20) into which a thermostatic element (25) which is controlled by water temperature is installed as a setting member for a regulation member (30) which cooperates with a valve seat (34) with a flow opening (35) between inlet and outlet channel (21, 22) of the valve housing (20) for regulating the water flow rate. It is desired in drinking and service water supply devices that strongly cooled-down hot water is replaced as rapidly as possible by heated water to avoid, if possible, germ formation in the water and a drop of the water temperature at the consumer.

  • Publication number: 20150306701
    Abstract: Apparatus and method for connecting a connection element of a power semiconductor module to a conductor track by welding. The apparatus includes an abutment for the arrangement of the substrate. The abutment has first and second partial abutments. The first partial abutment is a metal shaped body with a modulus of elasticity of between 50 and 300 kN/mm2, and the second partial abutment is an elastic shaped body with a modulus of elasticity of between 10 and 500 N/mm2. A bottom element rests on the second partial abutment. The apparatus further includes a holding device to fix the bottom element on the abutment; a sonotrode; and a positioning device for positioning the connection element in relation to the substrate.

  • Publication number: 20150057897
    Abstract: In a rigid axle assembly, a trumpet housing has a longitudinal axis (Z) and comprises a first portion (9a) extending along the axis with a substantially constant profile, and a second portion (9b) attached to the first portion and with a profile that increases in distance from the axis as the distance from the first portion increases. The housing further comprises, at a position (P2) adjacent the junction (P0) of the first and second portions, an attachment area shaped to receive a strain sensor (30) for determination of a wheel load.

  • Patent number: 8573019
    Abstract: A method produces a bent part by two- or three-dimensional bending of an elongate workpiece, in particular a wire or tube, in a bending process wherein at least one portion of the workpiece is moved into an initial position in the region of engagement of a bending tool by one or more feed operations by the coordinated activation of the movements of driven machine axes of a bending machine numerically controlled by a control device and is formed by bending in at least one bending operation with the aid of a bending tool. The movements of the driven machine axes are generated according to a movement profile predeterminable by the control device of the bending machine and include at least one oscillation-relevant movement leading to an oscillation of the free end portion of the bent part. During an oscillation-relevant movement, a compensating movement, reducing the generation of oscillation and/or damping the oscillation, a machine axis is generated in at least one compensation time interval.
