Patent DE-3217824-A1 (DE)
Inventor: MUSSELMANN WALTER
IPC: D21D5/02
Filed: 1982-05-12
Abstract: A rotor for a sorting apparatus for cleaning fibrous suspensions such as produced from the making of paper is described. The rotor is equipped with sorter blades which extend substantially parallel to the axis of rotation and are set at a desired angle relative to the direction of rotation of the rotor so as to create a hydrofoil effect. The sorter blades are mounted to one or more supporting walls shaped in a spiral form to provide spiral surfaces which are coaxial with the axis of rotation of the rotor and impart a conveying motion to the fibrous suspension. Upon rotation of the rotor in a fibrous suspension entanglements by impurities are avoided and the danger of the occurrence of a blockage of the strainer used in the sorter apparatus is reduced.

Title: Process for burning carbonate-type raw materials
Inventor: QUITTKAT WOLFRAM DR ING
IPC: C04B7/44
Filed: 1982-05-14
Abstract: In a process for burning carbonate-type raw materials in a rotary kiln with an upstream preheater, for example to give cement clinker, the calorific value of waste materials is utilised by generating pyrolysis gas for the generation of heat in the burning process, namely by recovering a pyrolysis gas mainly low in ballast gas by indirect heating of the dried waste materials, the pyrolysis gas then being burned in the hottest part of the preheater. This measure achieves the greatest possible utilisation of the pyrolysis gas for the burning process, while restricting the pollution of the environment to the unavoidable minimum.
Patent DE-3221422-A1 (DE)
Title: Single-vane wind turbine with control of centrifugal force
Inventor: GOSLICH HANS-DIETRICH ING GRAD
IPC: F03D7/02
Filed: 1982-06-07
Abstract: Single-vane wind turbines require a counter-weight rates to the vane in order to balance the rotating system. According to the invention, the counter-weight for controlling the wind turbine is provided as a function of the wind speed by being divided into part weights which are arranged outside the rotor plane. Under the effect of centrifugal force, the part weights tend to move into the rotor plane. If the vane is mounted rotatably about its longitudinal axis, the movement of the part weights can alter the setting of the vane with reference to the rotor plane. The control movement works against a prestressed spring, in order to be able to pass through a minimum speed range, generally up to the rated speed, without vane control. Dividing the counter-weight into further part weights makes it possible, on the one hand, to provide further control operations on the basis of the same physical relationships and, on the other hand, to use only a part of the whole counter-weight for the purpose of control. In this case, the residual mass of the counter-weight remains in an extension of the vane axis. The shaping of the counter-weight carrier, can moreover, influence aerodynamic processes. For example, streamlined cladding can lead to reduction in the generally harmful resistance in the direction of rotation, or favour the start-up response of the rotor by twisting the struts, which are of planar design.

Patent DE-3246295-A1 (DE)
Title: Oscillator with frequency modulation capability
Inventor: HEISE RUDOLF
IPC: H03C3/22
Filed: 1982-12-14
Abstract: If oscillators with frequency modulation capability, for example for the UHF band, are to be switchable within a relatively wide frequency range, they must be dimensioned with respect to the linearity of the slope of the capacity diode active for the control of the resonant oscillator circuit in such a manner that the modulation deviation is approximately of the same magnitude within the entire range independently of the frequency set. In modification of the circuit known from German Offenlegungsschrift 2608189, it is proposed to implement it in the frequency range above 300 MHz by omitting a tap in the resonant circuit inductance (L) for coupling the series resonant circuit (Rs, Ls, Cs) to the resonant oscillator circuit and, instead, including in the resonant circuit a capacitive network (CN) with a capacitor voltage divider (C1, C2) via the tap of which the series resonant circuit can be coupled in. <IMAGE>

Filed: 1982-12-16
Abstract: The invention relates to pneumatic vehicle tyres, the beads of which, with laterally bulging side walls, bear against the inner circumference of the rim with seating faces located on the outer circumference. In order to simplify the curing and press moulding of these tyres, the press moulding of the tyres is performed with side walls bent laterally outwards and seating faces situated on the inner circumference of the beads. The pneumatic tyre press-moulded in this way is then subsequently converted into the form for use by deforming its side walls.

Title: Programmable switching mechanism for generating angle-dependent output signals
Inventor: SCHMIDT STEFFEN
IPC: G05B19/07
Filed: 1983-03-12
Abstract: The invention relates to a programmable switching mechanism consisting of a digital/absolute angle transmitter and an evaluating unit arranged separately from the former, for generating angle-dependent output signals for further processing in a control device, particularly in a two-channel electronic press safety control. The invention is intended for implementing a programmable switching mechanism which satisfies the safety requirements for a press control with little electronic complexity, has high noise immunity with sufficient angular resolution and is equipped with a simple wear-free angle transmitter. This results in the object of having to incrementally readjust the switching-on and -off points of the control signals with low angular resolution, generated in a digital/absolute manner, within a certain angular range. According to the invention, this is achieved by the fact that the switching points of the intermittent control signals are phase-shifted compared with the switching points of the control signals and the switching points of the output signals of the switching mechanism, generated in a digital/absolute manner, can be incrementally adjusted again within the n angle steps by logical combination with the control signals. <IMAGE>
