Title: Current determination system for control and regulation of reversible converter - current transformer circuit using series circuit of load resistor and parallel circuit of resistor and diode poled in conductive direction
Inventor: REISCHER WILHELM ING
IPC: H02M1/38
Filed: 1992-01-20
Abstract: An electronic evaluation circuit (20), for measuring the current actual value, has a threshold value switch (10) assigned to a current zero signal unit (12). A junction point (19) between a first resistor (6) and a higher value second resistor (7) is at a reference potential (M) of the electronic evaluation circuit (20). The first voltage appearing at the first resistor (6) is used for the current actual value measurement. A second voltage appearing at the second resistor (7) is used for the threshold value switch (10) of the current zero signal unit (12). The second voltage is short circuitable by a switch (17) across a further resistor (8) against the reference potential (M) for a period from a response of the threshold value switch till the occurrence of a consecutive control pulse for a converter valve. ADVANTAGE - Current actual value measurement current zero signal improved so that voltage decoupling of both occurring voltages results without significant increase in magnetisation for current transformer.

Patent DE-4243151-A1 (DE)
Inventor: KLEINE WERNER DIPL ING
IPC: E21B17/042
Filed: 1992-12-19
Abstract: The drill unit consists of a tubular head (1) and a connector (2). The tubular head (1) has an internal thread (4) for connecting to an external thread (5) of the connector (2). The internal and external threads (4, 5) have flat flank areas. In addition, the inside and outside diameters of the internal thread (4) of the tubular head (1) exceed the inside and outside diameters of the external thread (5) of the connector (2). Thus S-shaped pockets form between the threads (4, 5). The S-shaped pockets serve to receive the contamination caused by the drillings so that the easy running of the thread (4, 5) is retained and the parts of the drilling unit can be released from one another without special tooling. <IMAGE>

Title: Measuring device for determining soil properties
Inventor: TOELLE RAINER DR
IPC: G01N33/24
Filed: 1993-03-15
Abstract: In the case of a measuring device for determining soil properties, having a ceramic cell (9) inserted into the soil, the internal space of which ceramic cell is connected in gas-tight manner to a pressure-measuring device located outside the soil, the base body (1) has three openings (2, 3, 4) to which two taps (5, 6) and a pressure sensor (7) are connected in a gas-tight manner. A tube (10) extends from opening (3) to the interior of the ceramic cell (9). This ensures that fluid entering through the inlet tap (6) reaches the internal space of the base body (1) and can leave again through the outlet tap (5) only after it has passed through the ceramic cell (9). This passing of the fluid through the measuring device is used for removing gases and salts from the measuring device and can take place with the measuring device located in the soil. The pressure of the fluid passing through may be different from that of the free atmosphere, which allows calibration of the sensor without dismantling it. It is furthermore possible to use the measuring device for taking samples of the soil solution. <IMAGE>

Title: Apparatus for the transverse transport of tubes
Inventor: FORNACH KURT
IPC: B21B39/00
Filed: 1993-03-20
Abstract: An apparatus for the transverse transport of tubes, each tube resting at its ends on rail-like supports extending transversely relative to the tube, is to afford a solution, by means of which the transport of tubes of this type transversely relative to their longitudinal extension is simplified, whilst risks of accidents and injuries to the operating personnel are to be largely avoided. This is achieved by means of a push trolley (7) which is movable between the supports (3) and has a feed drive and which possesses at least one transport roller (26) which is variable in its position relative to the tube (2, 2a) and can be pressed onto the outer surface of the tube (2, 2a) and which can be driven in rotation for the rolling transport of the tubes (2, 2a) on the supports (3). <IMAGE>
Patent DE-4309238-A1 (DE)
IPC: F16L5/14
Filed: 1993-03-23
Abstract: A line connection (1) exhibits, on a knob-like temperature sensor (3), a single connection flange (10) for two connection portions (7, 8), inserted in parallel, of a capillary tube (5) and of a filling tube (6). The flange casing (15) is pressed into the gap between the connection portions (7, 8) in the manner of a tongue and groove joint, with the result that it forms connection sleeves, which are separated in the manner of goggles, but are configured in one part, and a spacer member (18) therebetween. The connection flange (10) bears a securing means (30) which is located at a distance from it and is intended for protecting the capillary tube (5) from buckling and securing it in a self-reinforcing manner against being pulled. A high degree of functional safety is thus obtained, along with compact and simple production. <IMAGE>
Patent DE-4314488-A1 (DE)
Inventor: THIEL JUERGEN DIPL PHYS
IPC: G01B9/02
Filed: 1993-05-03
Abstract: 2.1. Known relevant measurement methods and measurement arrangements have the disadvantage that their measuring resolution falls far short of the resolution which can be achieved using other methods, and that these methods are unsuitable for measuring sections which vary within an extreme range. 2.2. This disadvantage is overcome in the case of the measurement method according to the invention by using two measuring interferometers with respective measuring sections to which the beam of the same laser is applied. In this process, the reference section formed from the arithmetic sum or difference of the two measuring sections is kept constant. In this case, two interfering component beams are used to generate in each case at least one interference signal which is measured by means of photodetectors. In the actual measurement method, the air wavelength of the laser beam is continuously tuned between two wavelength values within a wavelength region free from modal discontinuities, and the integral phase changes in the respective interference signals is detected during the wavelength modulation. The measured distance can be determined from these phase changes and the length of the reference section. 2.3. The measurement method and the laser interferometer arrangement are especially suitable for absolute distance measurements. <IMAGE>
