Title: Circuit arrangement having a plurality of transistorised inverters which can be operated in parallel
Inventor: NAKAHARA KAZUHIRO DIPL ING
IPC: H02M7/5387
Filed: 1984-05-21
Abstract: In the case of a circuit arrangement having a plurality of transistorised inverters (1a', 1b') which can be operated in parallel and are supplied from a common DC voltage source (E), a plurality of parallel bridge arms are provided which in each case have at least one output transistor (T11 to T22). The bases of the output transistors in bridge arms whose phase is the same are in each case connected to one another via a resistor (RB1 or RB2 respectively). In consequence, this results on the one hand in uniform load splitting of the corresponding bridge arms and on the other hand the current load of the driver stages (DT11 to DT22) is equalised. <IMAGE>

Title: Multi-way fitting for redirecting directions of flow and/or controlling delivery rates of gaseous or liquid media carried in pipe conduit systems, in particular in tubular heat exchangers
Inventor: MERTEN FRITZ
IPC: F16K11/085
Filed: 1984-08-22
Abstract: In heat exchangers of air-conditioning systems, condensers, in which a liquid medium flows through tubes arranged in the heat exchanger, the degree of contamination of the cooling medium makes it necessary to clean the tubes at defined intervals by means of mechanical cleaning means, such as brushes. The fitting required for this purpose, for reversing the normal flow, should have a small volume and be of robust and simple construction. For this purpose the invention proposes a fitting in which in each case two tubular branches are arranged in in each case one plane and in which the plug which brings about the reversal of flow is rotatably mounted in the fitting. For this purpose, the plug has two flow passages in the normal direction connecting the tubular branches to one another over the shortest distance. For the reverse direction, the plug is provided with two helical passages which connect the tubular branches crosswise, independently of one another. <IMAGE>

Patent DE-3501397-A1 (DE)
Title: Air-conditioning installation
Inventor: LINKE BRUNO
IPC: F24F6/02
Filed: 1985-01-17
Abstract: The air-conditioning installation for humidifying and cooling rooms is constructed in such a manner that an air flow can pass through the installation, which is constructed in a box-like manner, by means of a motorised fan. Here, three or more frames strung with strings are set in vibration in the air flow. A water pump delivers water from a supply in the box onto the lattice of strings which are caused to deliver it immediately to the air flowing past. The air is consequently humidified and at the same time cooled. As in principle a great many more water particles can be delivered to the air flowing past from moving surfaces, it is obvious to create movable surfaces of the greatest possible size with the minimum expenditure of energy. This is carried out optimally by the strings moved in the air flow.

Title: Method and apparatus for pneumatically conveying articles of the tobacco-processing industry
Inventor: KAEGELER PETER
IPC: B65G51/02
Filed: 1985-10-31
Abstract: For conveying rod-like articles of the tobacco-processing industry, especially filter rods, in a pneumatic conveying line (3) from a transmitting station (1) to a receiving station (2) to which is connected a consumer, especially a filter-connecting machine (13), the transmitting station (1) is clocked in addition to the intermittent mode of operation characteristic of it, so that a pause in transmission follows the transmission of a certain number of filter rods (6) in each case. The ratio of the durations of the transmitting phases (T1) and idle phases (T2) to one another determines the transmitting output and the said phases are predetermined by clocking units (61, 62) in dependence on the filling level of the magazine (12) of the receiving station (2) of the transmitting station (1). Overall throughput is increased, despite the interrupted mode of conveying. <IMAGE>

Title: Gas-locked axial shaft seal
Inventor: ARENZ KARL ING GRAD
IPC: F16J15/34
Filed: 1986-04-11
Abstract: The connection point between an axially movable sliding ring (6) of the shaft seal and the bellows (12) necessary for the locking gas supply is arranged with the aid of an intermediate piece (14), to which the bellows (12) are welded, in the area centre of gravity of the radial cross-sectional area of the ring (6). As a result, bending moments which can lead to warpage of the sealing or sliding surface (7) of the sliding ring (6) opposite the shaft collar (3) are prevented. These moments arise as a result of different heat expansions which are caused by the use of different materials with heat expansion coefficients, which differ from one another, for the sliding ring (6) and the bellows (12) or the intermediate piece (14). <IMAGE>

Title: Hot-water single-flue boiler with concentric multiple waste-gas deflection device
Inventor: DREIZLER WALTER DIPL ING
IPC: F24H1/26
Filed: 1986-08-11
Abstract: The hot-water single-flue boiler with "hot" firebox is equipped with a waste-gas deflection device which is arranged behind the shortened furnace body and causes at least one double, concentrically inward-running deflection of the waste gases after leaving the heat exchanger in the region of the fire box, so that cooling of the waste gases at the boiler end to below the dew point can take place, without the commercial outside dimensions and inside dimensions of the hot-water single-flue boiler having to be of larger design. By an additional lengthening of the fire box with smaller diameter inside the waste-gas deflection device, it is additionally possible for the waste gases to be heated up again somewhat and thus led away "dry" into a normal chimney without falling below the dew point.
