Patent DE-4000265-A1 (DE)
Inventor: KUGLER KURT
IPC: F23G5/16
Filed: 1990-01-03
Abstract: This invention describes a process and apparatus for the combustion of wastes, wherein the wastes are combusted in a combustion chamber and the temperature of the combustion chamber is controlled by changing the amount of combustion air as a function of the slag flow rate. The combustion can be carried out substoichiometrically in a reducing atmosphere because of additives which are introduced into the slag in the form of fine dusts. On account of the substoichiometric operation, the requirement for fluid wastes and/or supplemental fuel is drastically reduced, the capacity of the rotary tubular kiln is increased and nitrogen oxides formation is reduced.

Title: Cross winding control - has integrated circuits at yarn tension sensors for increased precision in sealed units for protection
Inventor: LASSMANN MANFRED
IPC: B65H59/38
Filed: 1990-08-07
Abstract: The yarn tension monitors at a winder for cross wound bobbins, where the winding stations are controlled according to the monitored yarn tension, are integrated circuit units with electronic circuit components (101,102,103) and their electrical connections (105-109) leading outwards. At least one component (101) is structured to generate a voltage proportional to a pressure or mechanical tension, or vary its electrical value. This component (101) is connected to the integrated circuit block through a mechanical ccomponent, to transfer forces from the yarn in contact with it. Comparable integrated circuits are used of a similar type and are compared with a preset proportional value between the  yarn tension and an output signal at least at  one of the electrical connections (109), so that they can be exchanged without further adjustment. ADVANTAGE - As the integrated circuits are sealed units, they are protected from ambient influences to increase the precision of the cross winding control.

Title: Drive method for bending flat elastic plates - attaching polarised crystal plates to flexible plate and applying voltage to cause expansion by reverse piezo-effect
Inventor: RICHTER BERTA
IPC: H01L41/09
Filed: 1991-03-15
Abstract: A drive method for producing curving motion to bend flexible plastic plates involves joining one or more polarised crystal plates (2) to the flexible plate (1). When a voltage is applied to the crystal plates, they expand according to the reverse piezo effect, thus bending the flexible plate. Two crystal plates can be joined together so that, when a voltage is applied to one and a voltage is removed from the other, they undergo a common bending. USE/ADVANTAGE - For bending predominantly flat plates. The method is simply implemented without the need for heating.

Title: Carding roller adjustment while roller is in operation - uses at least one parameter of carded web to set appts.
Inventor: KNAKE ALFRED
IPC: D01G15/28
Filed: 1991-05-13
Abstract: To adjust the gaps between neighbouring carding rollers, such as the main roller and worker and/or stripper rollers, at least one of the parameters of the material to be produced such as the web or wadding is taken as one of the values to be applied to the appts.. As a material parameter, its surface is monitored optically to determine the consistency of the fibre distribution longitudinally and/or laterally. At the carding outlet, the material pattern is compared with a standard pattern stored in memory where both are digitised before comparison. The material parameter(s) is (are) measured across the material width at least at two points through a sensor assembly moving across the direction of material travel with at least one sensor travelling at the same speed as the material during a measurement action. ADVANTAGE - The technique allows the roller settings to be modified while the carding appts. is in operation according to the nature and quality of the material being produced as it is being processed.

Title: Cyclic absolute distance measurement for AC sync. motor driven shaft - using sine and cosine functions and sinusoidal reference signal of frequency differing from motor winding voltages
Inventor: ZWOLSKY STEFAN
IPC: G01D5/242
Filed: 1991-05-16
Abstract: The method of cyclic uses two functions mutually phase shifted by 90 deg. and which corresp. to the sine and cosine of the rotation angle. In addition to the voltage providing the power for a three-phase motor driving the shaft, a sinusoidal reference signal of a frequency different to all motor winding frequencies is fed to all the phase windings simultaneously. Variations in the reference signal amplitude are detected to each phase winding. The fluctuation frequency is separated from the reference signal and the signals from at least two windings added vectorially to produce two signals at the fluctuation frequency mutually phase shifted by 90 degree. USE/ADVANTAGE - Cyclic absolute position measurement is achieved without using resolver or similar for rotor position detection at rest.
Patent DE-4117228-A1 (DE)
Inventor: FREI WALTER
IPC: F16H59/04
Filed: 1991-05-27
Abstract: A gearshift device for electrically controlled gearboxes has a shifting lever capable of pivoting in two parallel planes and guided in slides that are provided with a cross link only in the area of a neutral shifting position. Such gearshift devices are particularly useful for construction machines. A lock that is actuated below an admissible speed of rotation prevents a shift into the opposite direction of travel over the neutral position. In higher speeds accidental faulty shifts are avoided by a step-by-step gearshift mechanism. The disclosed locks require only few regulation measures, since they contain two mutually independent locking systems.
