    Abstract: The invention relates to a method for producing hollow nickel titanium profiles with a small external diameter and/or small wall thickness by means of deformation, especially extrusion. According to the inventive method, a composite block is formed, comprising a solid core and one or several hollow blocks surrounding said core. The core and the hollow blocks are made of nickel titanium. The parts of the composite block are separated after deformation to obtain a wire (3a), a tube (1a) with a small diameter and a tube (5a) with a larger diameter.

    Abstract: A metering pump assembly includes a metering space (6) and a displacement body (8) which is linearly movable via a conrod (10). A helical spring (20) designed as a compression spring (20) impinges the conrod (10) with a force in a movement direction. The helical spring (20) at at least one axial end (24) is designed such that in a relaxed condition an end (26) of a spring wire projects axially with respect to a connecting winding (28).

    Abstract: The invention relates to a method and a device for monitoring a fluid flow delivered by means of a pump. In the method the pressure distribution of the fluid is continuously or quasi-continuously measured as actual values in partial areas of the pump stroke and compared with desired values. In the device at least one pressure sensor is provided for the continuous or quasi-continuous measurement of the pressure of a fluid at least in partial areas of the pump stroke and a comparator is provided for comparing the measured actual values of the pressure with desired values.

    Abstract: The method provides that a session code (K) can be agreed between a first computer unit (U) and a second computer unit (N), without it being possible for any unauthorized third party to gain access to useful information relating to the codes or the identity of the first computer unit (U). This is achieved by embedding the principle of the El-Gamal code interchange in the method, with additional formation of a digital signature via a hash value of the session code (K) which is formed by the first computer unit (U).
