Patent DE-3110364-A1 (DE)
Title: Steam power plant
Inventor: WIESER RUDOLF DR
IPC: F01K7/22
Filed: 1981-03-17
Abstract: The invention relates to a steam power plant working at high pressure (turbine inlet pressure 260-180 bars) and having high main steam superheating and intermediate superheating (540-700 DEG C), feed water extraction preheating, and condensation of the exhaust steam in vacuum. In order further to increase the thermal efficiency of such a plant, the number of reheating is increased to three or more, and at least one recuperator is arranged between the intermediate-pressure turbine housing and the low-pressure turbine housing(s) in the flow of the main working steam. Feedwater flows as desuperheating medium through said recuperator, and partial cooling of the working steam takes place in it (circuit diagram according to Fig. 1). The preheating end temperature of the feed water can be raised by this new type of additional feed water preheating to above the critical temperature of the water of 375 DEG C. The steam generator then acts only as a superheater. The intermediate superheaters are arranged directly at the steam turbine and heated by a circulating medium (water vapour or a metal melt). <IMAGE>

Title: Housing with a gas-extraction device
Inventor: HUDEC GEORGE
IPC: B08B15/02
Filed: 1981-07-06
Abstract: In a row of fume-extraction cabinets, each of the cabinets is closed by a door, and is connected via an associated line and a common collecting line to a common air-extraction fan. Within each line there is seated a rotatable throttle which is connected to an electric motor. The latter comprises a potentiometer. In a sensor element close to the door, a plurality of magnetically actuatable switches are installed, each of which is allocated to a respective resistor of a resistor series and, furthermore, to a magnet, which normally keeps the switch closed. When the door is opened, a plate attached thereto moves progressively between the switches and their associated magnets, so that the switches can open and allow the resistance of the resistor series to increase. This resistance, which indicates the position of the associated door, is connected to an amplifier which moves the electric motor and thus the throttle. The outputs of the potentiometers are summated by a summing amplifier, the output of which varies the speed of the fan.

Patent DE-3150743-A1 (DE)
Title: Undercutting device
Inventor: SZATHMARY JANOS
IPC: B23B51/00
Filed: 1981-12-22
Abstract: The device for undercutting a drilled hole in a concrete wall has an end milling cutter which can be driven by means of a portable drill and is mounted with its shank in a pivotable rotary bearing of a bearing part. The bearing part has an annular shoulder, which can be placed against the wall surface in the area of the hole aperture, and also a centring sleeve which projects axially beyond the annular shoulder and can be inserted into the drilled hole. The milling members of the end milling cutter are designed as elongated plates of a diamond-steel sintered mass which, orientated in one axial plane each and projecting radially beyond the shank surface, are welded to one shank end at equal angular distances from one another. To increase the undercutting angle, the plates are set out radially at an angle to the shank axis towards the shank end. The pivotable rotary bearing is designed as a self-aligning ball bearing which is adhesively bonded in place with its outer race in an annular recess, open at the margin, of the bearing part. Furthermore, an annular pocket for accommodating the inner bearing race in the pivoted state is located at the annular-recess base pointing towards the centring sleeve. The cutter shank has several peripheral grooves which are arranged at an axial distance from one another and into which a snap ring can be inserted which forms a collar which projects radially on the shank and can be supported against the inner bearing race. <IMAGE>

Title: Arrangement for recording communication traffic on permanently connected telecommunications lines
Inventor: DACHWALD GUENTER ING GRAD
IPC: H04M3/36
Filed: 1982-01-23
Abstract: Arrangement for recording communication traffic on permanently connected telecommunications lines. This arrangement requires the use of individual sensors (S1, S2, SN) coupled to the lines (L1, L2, LN) in each case by means of a transformer (Ü1, Ü2, ÜN), and of a central recording unit (AE) which contains a microcomputer (MC) to record charges, which polls the sensor outputs individually or in pairs via a clock signal and controls the application of test signals to the sensors. According to the invention, the test signals are in each case fed in here on the secondary winding of the transformer at the points (P11, P21, PN), during which time the transformer function is disabled by means of a saturation current in each case supplied via an additional winding (WS1, WS2, WSN). Feedback of the test signals onto the lines is thus prevented. Alternatively, this can also be achieved by means of a short-circuit winding allocated to each transformer. In addition, test signals are in each case fed in on a further secondary winding at the points (P12, P22, PN2) which simulate an output signal of a balance-measuring circuit. The test routine is controlled by a microcomputer (MCP) in a test unit (PE), which disables the transformer of the respective sensor (S1, S2, SN) under test via switching means (AS2), connects test generators (PG) via further switching means (AS1) to the test points (P11/P12; P21/P22; PN1/PN2) and evaluates the respective polled signal (X). <IMAGE>
