Patent DE-4313169-A1 (DE)
Inventor: BRENNWALD HANS PETER
IPC: H02M3/158
Filed: 1993-04-22
Abstract: Railway drives which are fed from an AC voltage network (1) or from a DC voltage network (2) at different voltages convert these feed voltages by means of two-quadrant converters (St1 - St4), which are operated as parallel-connected four-quadrant converters for an AC feed and as step-up or step-down converters for a DC feed, into an intermediate-circuit DC voltage (UD) which is as constant as possible. In order to reduce harmonics in the case of a DC feed, the two-quadrant converters (St1 - St4) can be connected via in each case one inductive impedance (L1 - L4) and switches (S8 - S11) to a positive pole (P) of a DC voltage intermediate circuit (11). The 2-quadrant converters (St1 - St4) are pulsed in a phase-shifted manner such that an 1-th two-quadrant converter is triggered or switched on (1/l) of a clock duration later than an (l - 1)th 2-quadrant converter. A ratio of the switched-duration or conducting duration to the pulse duration, that is to say a duty ratio  beta  of each of the l 2-quadrant converters is controlled to a value of  beta  = m/l, n = a number of converters >/= 2, 2 </= l </= n, 1 </= m </= l; where n, l, m are integers. Of the possible  beta values, that one is selected which corresponds best with the ratio of the input voltage (UF) and the intermediate-circuit DC voltage (UD). <IMAGE>

Title: One-hand soldering tip
Inventor: KNITTEL ELKE
IPC: B23K3/03
Filed: 1993-06-21
Abstract: The present invention relates to a one-hand soldering tip which enables precise soldering work as occurs in micromechanics to be carried out effortlessly by hand. With the use of the one-hand soldering tip according to the invention, it is possible to produce soldered points with extreme precision and safely put down the one-hand soldering tip between the individual operations without an additional stand. A soldering-tin stem 1 can be inserted by means of two support rods 6.1 into support stems 6 which are fastened to the front cap 7. Arranged on the handle 8 is a push-button switch 9 which makes the electrical contact with one of the two heating elements 27, attached in the tip stem 10, against a spring pressure. The soldering tin to be used is introduced in stages at the top into the soldering-tin stem 1 and slides down under its own weight during the melting. The soldering tin is heated only when the push-button switch 9 is actuated. Arranged in the soldering-tin stem 1 is a valve 14 which is formed from a piston 14.1 and the sealing lip 1.2. This valve 14 for the passage of the liquid soldering tin is opened upon mounting the expanding-spring tip 5 by the soldering-tin regulating rod 4 which is fastened to the piston 14.1 pushing the latter upwards and thereby opening the passage. The expanding-spring tip 5 can be of different design in accordance with the working conditions. <IMAGE>

Title: Boring implement for making bores in earth with different soil classes
Inventor: MOHRMANN MICHAEL
IPC: E21B10/08
Filed: 1993-09-22
Abstract: In the microtunnel boring method, the boring heads have to be adapted to the soil types to be expected in each case. Soils with varying soil types often cannot be coped with. The novel device is to be able to bore in all soil types without adaptation work. To this end, the scraper disc (1), due to its mounting on a shaft journal (6a) which is set at an acute angle relative to the main shaft (6), is set in a high-frequency wobbling movement via a motor (11) driving the main shaft at high speed. Thus, the cutters (3) on the arms (1a) of the scraper disc can work the heading face in a percussive manner. A gear (1b) arranged on the scraper disc (1) runs in a fixed gear (8a), as a result of which a slow rotational movement of the scraper disc is superimposed on the high-frequency wobbling movement. Due to the superimposition of both movements, both rock and soft soil can be worked equally well with the boring machine. <IMAGE>

Title: Electric through flow heater
Inventor: FRIEDRICH BALDUR
IPC: F24H9/20
Filed: 1994-07-01
Abstract: The through flow electric heater has a simple star connection with a first set of switches (7, 8) in the first two arms and with a third switch (9) in the third arm. The first two switches are closed when a minimum water flow level is reached and the third switch is closed when a second, higher water flow is reached. Two of the arms each have two parallel heating elements (2, 3, 4, 5) with a manual switch (10, 11) in one of the branches. In the low flow setting the third arm is not connected and the manual selection provides a second, higher heating setting to the basic setting. In the high flow setting the two manual switches provide three settings depending on whether either or both switches are closed. Therefore a total of five heating settings are provided. The switches are simple rocker switches.
