Title: Endless loading conveyor for a continuous batch-washing line
IPC: D06F95/00
Filed: 1984-05-04
Abstract: The present invention relates to an endless loading conveyor, mounted on props, for a continuous batch-washing line. For more than ten years, the same problems of manual underloading or overdosing with water, washing agent and energy have arisen in conveyors of this type. The invention provides a remedy here, in that it weighs the entire conveyor as a whole after the feeding of each individual compartment and carries out a new zero balance. According to the invention, this is carried out by means of a weighing device having an electronic weighing cell which is arranged between the props and floor and which is connected to a zero-balance device for the automatic taring of each individual compartment and a corresponding digital weight indication. <IMAGE>

Title: Process for the direct reduction of iron ore or iron oxide pellets to give sponge iron, and system for carrying out this process
Inventor: STADERMANN HANS
IPC: C21B13/02
Filed: 1984-06-12
Abstract: In the course of a process for the direct reduction of iron ore or iron oxide pellets to give sponge iron in a reduction furnace (1), hot reduction gas is injected through a reduction-gas inlet (4), the gas flowing upwards through the descending charge, reducing the iron ore or the iron oxide pellets in the process and being drawn off as top gas through a top-gas outlet (5). In a cooling zone (9) below the reduction zone (8) the sponge iron is cooled by means of a cooling gas which is supplied via a cooling-gas inlet (6) and is drawn off via a cooling-gas outlet (7) above the cooling gas inlet but below the reduction inlet. In the process, a portion of the cooling gas is shunted off and fed to the reduction zone, this portion being replaced by cooled and cleaned top gas. The cooling gas drawn off is cooled and cleaned in a cooling-gas scrubber (10), is passed through a compressor (11) and then cooled once more by a cooling-gas cooler (19). The cooling-gas fraction fed to the reduction zone is shunted off outside the furnace and admixed to the reduction gas upstream of the reduction-gas inlet, while the top gas replacing said cooling-gas fraction is admixed in, or upstream of, the cooling-gas cooler. <IMAGE>

Title: Control method and control device for controlling an asynchronous machine which is supplied via a converter having an intermediate circuit
Inventor: KAMPSCHULTE BURKHARD DR ING
IPC: H02P21/08
Filed: 1984-10-18
Abstract: In the case of this control method and this control device for controlling an asynchronous machine (29, 37) which is supplied via a converter having an intermediate circuit (26, 27, 28, 36, 38, 39) and has no speed feedback, a machine model is provided to which desired values for the rotor flux ( phi 2d<*>) and the torque (m<*>) are supplied on the input side and which, on the output side, emits desired-value components for the stator current (i1d<*>, i1q<*>) and the stator voltage (U1d<*>, U1q<*>) of a rotor-flux-related coordinate system and a desired slip-frequency value ( omega 2<*>). The stator frequency ( omega 1) is formed by addition of the desired slip-frequency value and an additional frequency signal ( DELTA omega <*>). The additional frequency signal is emitted by a power controller (44) which, on the input side, receives the desired value/actual value difference of the stator powers (P1<*>-P1). The desired value of the stator power (P1<*>) is formed from the desired-value components for the stator current and the stator voltage. The intermediate-circuit power, reduced by the invertor power loss (Pv), is used, for example, as the actual value for the stator power (P1). In order to prevent pull-out of the asynchronous machine if the pull-out slip is exceeded, the desired value/actual value difference of the stator powers has applied to it an additional, negative power signal ( DELTA P1). <IMAGE>

Title: Band, especially conveyor band, made of PTFE glass fabric with a connection point of mutually adjoining band portions
IPC: F16G3/10
Filed: 1985-02-20
Abstract: The connection point of mutually adjoining band proportions of the band, especially the conveyor band made of PTFE glass fabric, has, on the mutually confronting end faces of the band portions, oppositely directed bevels with oblique faces confronting one another. The oblique faces are connected to one another, preferably by welding, an intermediate layer being arranged between the oblique faces. When such conveyor bands are used, for example in the textile industry, the described design of the connection point avoids imprints on the conveyed material and an accumulation of dust and dirt at the connection point. It is advantageous, furthermore, that, during a cleaning of the band by means of scrapers, a premature wear caused by a constant butting of the scraper against the connection point is avoided.
