Patent DE-3111216-A1 (DE)
Title: Injection mould
Inventor: BLANK MICHAEL ING GRAD
IPC: B29C45/33
Filed: 1981-03-21
Abstract: The invention relates to an injection mould for mouldings in the form of crates, in particular bottle crates, in which the mould jaw is displaceable on inclined guide pillars on the movable mould half by means of a drive and in which a stripper frame is provided on the displaceable mould jaw and can be used to strip the moulding from the core of the movable mould half once the mould jaws have been opened. A drive for the ejector frame is described, with which it is ensured that, without limit switches and the like, the stripping of the moulding from the core commences as soon as the mould is open far enough that the moulding can drop out of the opened mould. The ejector frame is in this case penetrated by at least two guide pillars, which are fastened in one of the two mould halves and by which the said mould half is guided in relation to the other mould half in the opening direction. On the guide pillars there are respectively mounted axially displaceable bushes, on the outside of which the guide frame and the other mould half are mounted axially displaceably. The bush is provided with stops, which interact with the ejector frame on the one hand and with the other mould half on the other hand, the effective distance between the stops being chosen such that the ejector frame is taken along during opening of the mould as soon as an opening width required for ejecting the moulding has been reached. <IMAGE>

Title: Device for optimising the transient behaviour of the control variable of an electrical machine
Inventor: RISS JOHANNES DIPL ING DR
IPC: H02P9/10
Filed: 1981-07-24
Abstract: In the case of the device for optimising the transient behaviour of the control variable of a voltage-regulated electrical machine, especially the output voltage of a synchronous generator, according to the invention, an actuating element and a control path (which is the synchronous generator) are arranged downstream of a current regulator, and an actual-value converter is arranged downstream of said control path, and is arranged at the input of the current regulator of an addition point to which the output signal of a feedback path is applied, the output signal from a further addition point being applied to the input of this feedback path, to which addition point the output signal of a model function can be added whose input is connected to the input of the current regulator upstream of the addition point, and the output signal of the actual-value converter (which is inverted and corresponds to the output signal of the model function for a predetermined load case) produces a residual deviation, however, for every other load case at the output of the addition point. A voltage regulator is arranged upstream of the junction point of the model function in reverse parallel with which a limiter is arranged whose output is connected to a subtraction point at the input of the voltage regulator. In addition, a limiter is likewise connected from the output of the current regulator to this subtraction point and, furthermore, the output signal of the actual-value converter and the reference variable can be supplied to this subtraction point.
