Patent DE-3112725-A1 (DE)
Title: Control device for a baling press
IPC: B30B9/30
Filed: 1981-03-31
Abstract: The invention relates to a control device for a long-stroke baling press, in the case of which at least one control switch controls the press in dependence on and triggered by the displacement path of the pressing plate. The object of the invention is to develop the control of a baling press in such a way that all the control elements are arranged closely together in an assembly unit and that distribution of the said components along the pressing path or the path of the pressing plate is avoided. The object is achieved in that arrangements which proportionally reduce the displacement path, such as lifting blocks, levers and the like, are arranged between the pressing plate and the control switch, and all the control switches necessary for control of the press, such as microswitches, are combined in a single area, such as in a control block, for example, in the region of the reduced displacement path. It is equally possible for hydraulic control units known per se to be used to reduce the displacement path. Figure 1 contains a diagram of a device for reducing the pressing path, which device is composed of a lifting block. <IMAGE>

Patent DE-3118259-A1 (DE)
Title: Electronic PID controller
Inventor: PROELS HANS DIPL-ING
IPC: G05B11/42
Filed: 1981-05-08
Abstract: The PID controller contains a P section (1) which is supplied with the control error (xw), a PI section (2) which follows the P section (1), and a DT1 section (3) which is supplied with the controlled variable (x). A summing element (4) combines the output signals of these elements to form the manipulated variable (y). It is possible to switch the structure from PID characteristic to P, PD or PI characteristic by operating switches (5, 6), there being no change in the scaling of the adjusting elements for the controller parameters. The controller parameters (Kp, Tv, Tn) are changed by alternately switching between a minimum value and a maximum value, the duty ratio of pulse sequences determining the respective value. The structure of such a P, PI and DT1 section is specified, the P section allowing a reversal in characteristic, the PI section not having any integral saturation and the DT1 section allowing, in addition to the variation of the correcting time constants (Tn), a variation of the gain factor (Kp). Furthermore, the interconnection of two such controllers in the sense of a selection control is specified. <IMAGE>
Patent DE-3133179-A1 (DE)
Title: Replay device for video recordings on magnetic tape or disc
Inventor: KRAETZER HELMUT DIPL ING
IPC: H04N5/782
Filed: 1981-08-19
Abstract: The application extends to a device for replaying the video and audio information recorded on a magnetic tape or video disc. It is characterised by the fact that pickup device and video and audio replay section are combined in a single device. In the current state of the art, two devices, namely a normal television set and a video recorder or a video disc player are needed for this purpose. A further characterising feature consists in that the device is exclusively provided for replaying, that is to say that recording of television broadcasts is deliberately omitted. This results in not only a noticeable reduction in costs compared with the previous arrangement having two separate sets but also in no further television fees having to be paid. A further significant advantage lies in the fact that such a combined set is completely independent of the site of the television receiver normally needed since it does not require the presence of such a receiver at all.

Patent DE-3202784-A1 (DE)
Title: Automatic sliding-door system
IPC: E05F15/73
Filed: 1982-01-28
Abstract: The invention relates to an automatic sliding-door system having at least one stationary side wing and at least one sliding-door wing and a respective inner and outer movement transmitter which senses the passageway region and which gives the door drive the opening command. The closing command occurs automatically after a specific time has elapsed. If a movement transmitter responds again during the closing operation, a change-over to opening takes place once more. It has been shown to be a disadvantage that the movement transmitters cannot cover the entire space laterally of the sliding-door wings, with the result that users have been able to walk from the side into the closing door or have been in danger of being jammed by the door wings moved outwards. This danger is eliminated in that there is arranged in the door plane an additional safety sensor which responds when a person enters the opened door aperture or the lateral region of movement of the door leaves and which changes the door drive over to crawling speed in the opening direction.

Title: Soft-material compensator and process for preheating and cooling a soft-material compensator
Inventor: TEMPLE BERNHARD DE PROF DIPL I
IPC: F16L53/32
Filed: 1982-06-21
Abstract: In systems with extremely high gas temperatures which can also be extremely non-stationary, it is not sufficient if only the soft-material compensator consisting of flexible materials is protected from the high temperature, but on the contrary the rigid flange parts and body parts of the compensator must also be protected from the rapidly occurring and gradually dying temperature gradients in the components. The invention, for example according to Figure 1, provides the solution which deals with both factors. Elastic hollow-spaced baffles and deflection plates with reflectors and with suitable also nozzle-like orifices, from which the heating or cooling gas, which can also be extracted from the system, flows, precede the soft material. For example, gas-turbine combination blocks, when started up, supply from one of their compressor stages sufficient hot air which, according to the invention and according to the process, can be used to preheat the frame parts of the soft-material compensator. In contrast, under full load, the gas/air from this turbine stage takes over the cooling both for the clamping point and for the flexible soft material. According to the invention, therefore, insulation, convection and radiation effects act to control the thermally and mechanically non-stationary temperature and heat effects. <IMAGE>
