Abstract: In the method for determining controlled system parameters "delay time" and "compensation time" with the aid of the tangent at the turning point of a step response at the output of a higher-order controlled system, the tangent with the steepest gradient is determined by means of regression calculation over N measurement points, the points of intersection of which tangent with the time axis of the straight lines which are parallel to the time axis and correspond to the static end value bounding compensation time and delay time. The invention is used in the design of control circuits for processes and for producing process models. <IMAGE>
Patent DE-3539132-A1 (DE)
Title: Dabber printing machine
Inventor: MORLOCK RUDI
IPC: B41F17/00
Filed: 1985-11-05
Abstract: In the dabber printing method, the dabber (11) is firstly lowered onto the block table (3) by means of a toggle lever (6) and pressed onto the inked block, thereby receiving the printed image. Subsequently, the slide (4) bearing the toggle lever (6) is displaced over the printing table (2) and printing then takes place on the workpiece. In the known constructions, during this process the relatively high pressure of the order of magnitude of 600 kg is absorbed by the guides (5) of the slide (4), as a result of which bending, damage and the like may occur. This is avoided by providing the supported end (12) of the toggle lever with a support member guided displaceably on the slide and by the machine frame (11) having support surfaces for the support member (13) within the range of movement of the slide (4). <IMAGE>

Title: System for the production of plastic semi-finished product from foamed plastic
Inventor: REIFENHAEUSER HANS
IPC: B29C48/85
Filed: 1986-01-03
Abstract: System for the production of plastic semi-finished product from foamed thermoplastic by means of a melting and homogenising device, a cooling device and discharge gear pump. The melting and homogenising device has an upstream-connected plastic feed device at one side and at the other side a downstream-connected blowing-agent feed device. The melting and homogenising device and the cooling device are each equipped with at least one extruder screw in corresponding barrels. The screw speed, discharge gear pump speed and blowing agent feed are interlinked via a closed-loop control device equipped with a microprocessor. The extruder screw of the melting and homogenising device and the extruder screw of the cooling device are combined to form one screw shaft, which has an annular-clearance transition component with conical annular clearance. The screw shaft is adjustable axially and by this means the thickness of the annular clearance is adjustable and the feed pressure of the blowing agent can be influenced. The control device keeps the ratio between the gear pump speed and the blowing agent feed constant, with a predeterminable ratio and, with the aid of at least one temperature sensor arranged in the annular clearance, monitors the clearance-width boundary values. <IMAGE>

Title: Multi-fuel carburettor
Inventor: SEKIYA MITSURU
IPC: F02N19/00
Filed: 1986-11-17
Abstract: A multi-fuel carburettor for an internal combustion engine is presented in which alcohol is used as main fuel and alcohol together with petrol are injected until the engine is warmed up. Petrol therefore serves as secondary fuel. When it has been detected that the cooling water temperature lies below a predetermined value ("warm engine"), a temperature-controlled valve opens a vacuum line so that a vacuum-controlled valve opens a petrol feed line and petrol together with alcohol are injected by way of a main nozzle. At the same time, a petrol feed pump is started by means of a vacuum-controlled switch which is in effective connection with the temperature-controlled valve. When the cooling water temperature lies above a predetermined value, the temperature-controlled valve reacts in the reverse direction and closes the petrol line. Alcohol alone then continues to be injected by way of the main nozzle.
Patent DE-3702253-A1 (DE)
Title: Saw chain
Inventor: NITSCHMANN KARL
IPC: B27B33/14
Filed: 1987-01-27
Abstract: In the handling of motorised chainsaws, owing to a sudden increase in resistance a kickback may occur, where the saw is flung upwards and rearwards. Accidents resulting therefrom are to be feared above all when the saw is placed on to the wood. The kickback is caused by the reaction forces which result from the advance and the cutting forces.   Among the articulatedly connected chain links, the cutting links and/or the safety links of the saw chain are pivotable in relation to the plane of action in which the articulation axes of the chain links lie. Here, with a driven saw chain, under the action of the tensile force, these pivotable working links are pivoted out in such a way that there is no clearance angle present at the cutting links and the safety links cover the cutting links in the circumferential direction by means of their projection. During the advance of the chainsaw, the working links are pivoted only on the stretched forward-running chain section into their working position by the reaction forces, which are therefore unable to increase suddenly.
