Patent DE-4209053-A1 (DE)
Inventor: SCHILLINGER JAKOB DR
IPC: H02M3/158
Filed: 1992-03-20
Abstract: A switching regulator system supplies a constant output voltage from a large range of input voltages. The input voltage may be lower or higher than the output voltage. This large regulation range is achieved by combining a down converter and an up converter with a common storage choke coil in a final power stage. The storage choke coil is advantageously designed as a flat coil produced by the multilayer technique and having a coil core. This new kind of switching regulator system combines two converter concepts known per se having different characteristics.

Title: Control voltage generator for flashing direction indicators - stabilises current through protective resistance irrespective of which of two alternative voltages of power supply is operative
Inventor: WAEGNER HANS-JUERGEN DIPL ING
IPC: B60Q1/38
Filed: 1992-07-22
Abstract: The voltage for the flasher unit is generated by two symmetrical current-mirror configurations. One npn current mirror (T1-T3) has a reference branch connected by a resistance (R1) to a supply voltage (Us) and feeds a voltage divider (R3/R5) connected externally to a direction indicator switch (S1). The other current mirror (T8-T10) and its resistances (R4,R6,R7) are dimensioned so that a constant current flows through a protective resistance (Rs) irrespective of whether the switch is returned to the vehicular earth (-31) or to the supply. The output transistor (T10) draws a constant 1 mA current either from the supply, or via a diode (D1) from the first current mirror. ADVANTAGE - Voltage drop across protective resistance is independent of temp. fluctuations whether supply voltage is 12 or 24 Volts.

Title: Process and apparatus for the production of seamless tubes by pressure-rolling
Inventor: HAEUSLER KARL HEINZ
IPC: B21B21/00
Filed: 1993-04-21
Abstract: The invention relates to a process and an apparatus for the production of seamless tubes by a pressure-rolling of a rotationally symmetrical bloom of nonferrous metal via a mandrel by means of a plurality of pressure rollers which can be laid against the outer circumferential surface of the bloom and which can be braced axially relative to the bloom and, simultaneously rotating, draw the bloom over the mandrel to form a tube. In order to allow even very high decreases in cross-section, it is proposed that the drawing take place in steps in a plurality of successive axial strokes, the pressure rollers, on the forward stroke, moving together in a controlled manner towards the bloom and, on the return stroke, being moved back, opened, into the new initial position. For this purpose, the pressure rollers (4a, 4b) are arranged distributed around the bloom (1) in a rotary-driven cage (9), and the cage (9) can be moved forwards and backwards relative to the bloom (1) by the amount of a feed length (L), the pressure rollers (4a, 4b) being capable of being thrown on relative to the bloom (1) at least during the forward movement. <IMAGE>

Title: Residual fixing force determn. method for riveted thin-wall components
Inventor: DEHLKE KLAUS DR ING
IPC: G01L5/00
Filed: 1994-01-17
Abstract: The method involves using pressure sensors suitably dimensioned to permit their insertion between the components/testpieces. During, e.g. a blind-rivetting process, the sensors transmit the compressive force (F) generated as a result of the deflection of the flexible materials being jointed.  The deflection of the materials takes place within their elastic limits. On completion of the rivet deformation phase, followed by shearing of the rivet stem, the display indicates the residual force imposed by the rivet on the RHS of the peak.

Filed: 1994-01-19
Abstract: A beer crossflow-microfiltration process is disclosed. In order to avoid fouling of the filter module membrane by the ingredients of the non-clarified beer to be filtered out and that form a covering layer on the membrane, filtration is interrupted from time to time. During a following short pause, the covering layer on the membrane is chemically dissolved with lye, and the covering layer is removed by backflushing the membrane with water. In order to improve filtration, the transmembrane differential pressure (p) is controlled during the filtration phase according to a substantially periodical time function and the flow velocity (v) of the beer through the membrane is substantially continuously increased.
