    摘要: A moveable skid is provided to sense the height of a pallet fed to a raisable and lowerable platform. The skid determines the height of the pallet before it is fed to a raisable and lowerable platform of a sheet stacking apparatus so that the position of the pallet below an intermediate stacking platform can be determined during the pallet change. This prevents adverse effects by nondetrimental projections above the surface of the pallet and prevents an excessive drop of the intermediate stack as it is transferred to the pallet.

    摘要: A stacker for sheets, e.g. of cardboard or paper, is equipped with a device for inserting Marker strips or tabs within the stack to indicate predetermined numbers of sheets therein, e.g. for identification of reams. The inserter has a rigid channel Mounted on a frame moveable on a traverse transverse to the direction of sheet feed and the channel at its outlet is rigidly connected to a tongue having a substantially horizontal underside and moved with the outlet of the channel in a rectangular pattern with only vertical and horizontal path segments so that the tongue can be withdrawn from the stack without changing its orientation horizontally after a strip has been inserted into the gap formed by the tongue in the stack and alongside the tongue.

    摘要: To determine and/or automatically control the degree of orientation of tubular films which have been made in a film-blowing plant including an extruder having a film-blowing head and apparatus for internal cooling and also including flattening and take-off apparatus, the rate of exchange of the air for internal cooling, the speed of the extruder, the temperature of the plastic composition being extruded and/or the take-off velocity are controlled. To ensure that the degree of orientation can be determined and/or automatically controlled in a simple manner and without an occurrence of trouble, that shape of the flaring portion of the bubble which corresponds to the desired degree of orientation is determined and/or adjusted and is recorded as the desired shape of the bubble. The actual shape of the flaring portion of the bubble is detected and compared with and adapted to the desired shape.

    摘要: A process for making a thyristor device protected against breakover firing is to generate in the semiconductor body (1) of the thyristor an area (A) which has a lower breakdown voltage than the rest of the semiconductor body. This area is protected by suitable measures when the thyristor is overloaded. The invention features a process in which the area (A) of the semiconductor body (1) is irradiated locally with protons, with the proton energy being measured in such a manner that the maximum of the defect density and doping generated by the proton irradiation lies between the PN junction (15) of the first base region (9) and the second base region (10) and the half thickness of the second base region (10), and the semiconductor body (1) is subsequently heat-treated.
