Patent DE-3231378-A1 (DE)
Title: Firing for solid fuels
Inventor: WOLFF WERNER DIPL ING
IPC: F24H1/40
Filed: 1982-08-24
Abstract: The invention described offers special advantages for fluidised bed firings, because a large build-up of temperature can take place in the fluidised bed during these firings either as a result of cooling elements being built into the fluidised bed, or a corresponding air supply and if necessary a backfeed of flue gas being fed into the fluidised bed. This withdrawal of heat from the fluidised bed makes it possible to keep the firing temperature from the fluidised bed below the slag melting temperature, and thus to prevent the slagging or sintering of the fire space or of the afterburning space. A further advantage results from the feeding back into the firing of a large part of the fly coke and fly ash which are carried from the firing by the furnace gases in especially large quantities in fluidised bed firings.
Patent DE-3235583-A1 (DE)
Title: Portable, case-like miniature office
Inventor: LUMMERT HANS-JOACHIM
IPC: A45C11/24
Filed: 1982-09-25
Abstract: The miniature office is based on the concept of providing a working container, depending on the dimensions and fittings, which in an individual design can be used for carrying out all conceivable office and typing work in the widest sense. Compared to previously supplied containers which were provided solely for partial areas and the accessories used therein, it provides the advantage that it can accommodate equipment for wide-ranging applicability. This wide-ranging applicability is made possible by the type of design, by means of which the miniature office is distinguished from that previously known in such a way that everything can be joined together to form a compact unit, thus making it unnecessary to use different individual containers.
Patent DE-3236128-A1 (DE)
Title: Circuit arrangement for telecommunications switching systems, particularly telephone switching systems, comprising space-division switching devices and junction circuits at their inputs
Inventor: BUETTNER GERHARD DIPL ING
IPC: H04Q3/42
Filed: 1982-09-29
Abstract: In a telephone switching system with space-division switching devices (Gzv/Gv/Gsv, Gsr/Gr/Gzr,Kb) and junction circuits (Ev/SV/SR/ER, TV/RV, RR/TR, VS) at their inputs, four-wire through-connection is effected via space-division multiplex switching network (Gzv/Gv/Gsv, Gsr/Gr/Gzr,Kb) on the transmission of connection-individual communication signals and also connection-individual signalling signals in continuous alternation and both in PCM form but without time-division multiplex. An idle test is effected via the backward channel (Gzr) of each seizable four-wire path to be tested (ZL). In the idle state, the backward channel (Gzr) transmits continuous PCM signals. Seizure is effected by PCM seizure signal via the forward channel (Gzv, Gv, Gsv) whereupon the continuous signal indicating idle state is disconnected again. <IMAGE>
Patent DE-3236916-A1 (DE)
Title: Ultra-light tank and demonstrator barrier bodies
Inventor: ZUNIGA CANDIDO
IPC: E01F13/02
Filed: 1982-10-06
Abstract: Barrier bodies consisting of a very light material, for example hard foam, separate or connected to one another, prevent the advance of tanks or demonstrators. The barrier bodies can receive a magnetised metal upper layer. They can thereby be swirled up by the relative wind of the tanks and remain stuck to the tank. The tank advance is impeded because vision is obstructed by the barrier bodies sticking to the tank and to one another. Moreover, mines are or could be contained in part of the barrier bodies, and therefore the penetrating tank has to take appropriate precautions. Demonstrators are impeded because of the large dimensions of the barrier bodies and the mutual magnetic attraction of these. The weight of the barrier bodies is minimal, thus substantially increasing their possibility of transport. It is also possible to produce them on the spot.

Title: Method of suppressing inferences induced by two-way propagation and circuit arrangement for this purpose
Inventor: KAESSER JUERGEN DIPL PHYS DR
IPC: H04B1/12
Filed: 1982-12-22
Abstract: A method is specified of suppressing interferences in the reception signal of a radio receiver, in particular of a car radio, which are induced by two-way propagation of a frequency-modulated transmission signal, in which the reception signal is subjected at the same time to an FM demodulation and an AM demodulation for the purpose of eliminating the interferences completely. The signal component obtained by the AM demodulation is used to generate a synthetic signal which is identical to the interference signal contained in the signal component obtained by the FM demodulation. Subtractive superimposing (heterodyning) of the synthetic signal and of the signal component obtained by the FM demodulation compensates completely for the interference signal. Advantageous circuit arrangements for realising the method are indicated.

Patent DE-3307667-A1 (DE)
Title: Precision cross-winding machine
Inventor: MAYER MANFRED DR ING
IPC: B65H54/08
Filed: 1983-03-04
Abstract: What is described is a precision cross-winding machine for the winding of very slowly supplied filament yarns, which is characterised in that a special three-phase short-circuited rotor motor having a selected torque characteristic at the motor speed occurring during the winding travel is used in conjunction with a reduction gear for the rotational speed of the winding spindle. The winding heads are especially suitable for the winding of carbon yarns to form precision cross-wound bobbins, for which additional measures are taken, such as, for example, the sealing off of the driving elements against the penetration of fibre fly (graphite dust) and high bending radii at the deflection points. A further particular feature of the precision winding heads described is the absence of the hitherto conventional dancer arms for controlling the drive motors and the compact design of the machine as a result of the horizontal guidance of the traversing housing together with the reverse-thread shaft and the traversing yarn guide.

Patent DE-3319186-A1 (DE)
Inventor: FISCHER HERMANN DR
IPC: G01N27/409
Filed: 1983-05-27
Abstract: In said method, the measuring electrode and the counter-electrode are exposed to exhaust gas and present an adjustment which causes alternating changes between the rich and lean operations. Furthermore the counter-electrode is so arranged that the sensitive time and the dead time upon the passage of gas from the rich to the lean operation deviate from the sensitive time and the dead time upon the gas passage from the lean to the rich operation. Therefore, the counter-electrode has asymmetric sensitive times. A rich reference is preferably used wherein the sensitive time and the dead time upon the gas passage from the lean to the rich is shorter than the passage from the rich to the lean. Furthermore, the counter-electrode is provided with an anti-diffusion layer which presents pores having diameters which are small with respect to the mean free travelling length of oxygen molecules. Thereby, the measuring electrode does not make loop oscillations in the rich to lean direction and generate a substantially constant potential which may be used as a reference potential for the probe.

Title: Construction unit
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: F04C18/344
Filed: 1983-07-09
Abstract: For a construction unit consisting of two parts joined together by a preferably circumferential, continuously closed joint, different solutions are given for connecting the two parts of the construction unit together and simultaneously sealing them in the same operation. Each of the two especially cylindrical or disc-shaped components has a groove extending along the joint and inclined to the plane of the joint, the two grooves being disposed in such a manner that they communicate with one another when being installed in the joint plane. In the assembled state, the grooves are filled or injected with a curable material which is poured in in a liquid or flowable state, for example a plastics or metal melt. To this end a gate opening and a vent opening, which is offset with respect to the latter and is in connection with the joints, are provided in at least one of the two components. It is essential for all embodiments according to a joining technique of this kind that the grooves - seen in axial section - do not face in a direction in which the machine parts can be easily separated from each other by external or internal forces. The advantage of the joining technique described is that the type of join is very simple as regards production technology and especially easy to automate.
