Patent DE-4209265-A1 (DE)
IPC: E04C5/12
Filed: 1992-03-21
Abstract: A tensioning rod (5) made of fibre-laminate, for use as an anchor element in foundation engineering or mining or as a reinforcing element for concrete in the areas intended for anchoring, is provided with continuous ribs (10) which are produced by embossing, run along a helical line and form a thread (9) and onto which an anchoring body (12) provided with a corresponding internal thread can be screwed. To obtain a radial pressure on the tensioning rod (5) as a result of wedge action, the angle of inclination (alpha) of the flanks (14) of the ribs (10) to the longitudinal axis of the tensioning rod (5) is less than 45 degrees; the ribs preferably form a flat trapezoidal thread. In an anchoring body (12) which is rigid against annular tensile forces, the radial applied pressure on the tensioning rod (5) is increased by the flat setting angle of the flanks (14) of the thread ribs (10), which leads to a greater depth effect and to a higher shearing resistance. By means of annular tensile rigidity of the anchoring body (12) variable over the length of the thread engagement, specific widening of the anchoring body (12) can be achieved at the point of high stress concentrations, with the result that a change in length of the tensioning rod (5) can occur. <IMAGE>

Title: MOSFET with temperature protection
Inventor: TIHANYI JENOE DR
IPC: H03K17/08
Filed: 1993-02-18
Abstract: Between the gate and source electrodes (7, 8) of a MOSFET (1), a switching element (2) which is thermally coupled to the MOSFET (1) is connected which switches off the MOSFET (1) when a critical temperature is reached. The switching element generates a temperature-dependent signal by means of which a device (3) is controlled. The device (3) switches on a voltage reducing element located between the gate and source electrodes (7, 8) of the MOSFET (1) when a temperature is reached which is lower than the critical temperature. As a result, the gate-source voltage of the MOSFET and thus the current flowing through it are reduced. The temperature rise is slowed down. <IMAGE>

Patent DE-4306313-A1 (DE)
Title: Monitoring of district-heating ducts and lines
IPC: G01M3/18
Filed: 1993-03-01
Abstract: All types of incident in district-heating networks can be detected by temperature measurements in the control ducts with only three temperature sensors of high reliability. Furthermore, the fact that the types of incident differ from one another by very characteristic temperature-time profiles is utilised. The special feature of the measuring method used is also the fact that it is sufficient to monitor the control ducts; this leads to a cost-effective monitoring system. In addition, the cabling problem is taken into account by the information being transmitted digitally/serially via existing signal lines for central analysis of fault indication to the central control station of the district-heating network. An autonomous measuring unit is therefore necessary in each duct; it must have the following characteristics or line features: Analogue/digital converter inputs for at least three temperature sensors, microcontroller, since the system has to carry out the analyses of faults locally in order limit the data quantity in the data network. Serial data-bus connection according to RS 422/RS 485 standard for data transmission, power supply via the signal lines.
