Title: Polishing stack for thermoplastic sheets and films of different melt viscosities
Inventor: LECHLER HELMUT
IPC: B29C48/08
Filed: 1983-05-27
Abstract: Polishing stacks consist as a rule of polishing rolls, the surface of which reproduces the mirror image of the surface of the produced thermoplastic product. The aforementioned invention operates with a polishing belt. This polishing belt is pressed by an elastic roll onto the surface of the thermoplastic in such a manner that a contact surface results at the contact line. In the transverse position the flexible polishing belt can thus bridge small differences in thickness of the sheets or films produced and produce the surface qualitatively in the manner of an elaborate calender polishing stack. Optionally the surface can also be grained by the same process and provided with structures. The device consists of a sheet die (1), a polishing roll (5), an elastic backing roll (9) and a polishing belt (8).

Title: System for discharging charges on test specimens in scanning electron microscope investigations
Inventor: GAENG LUTZ-ACHIM DIPL ING
IPC: H01J37/02
Filed: 1983-09-07
Abstract: The invention relates to a system which can easily be adapted to any scanning electron microscope and permits both electrically nonconductive and vacuum-sensitive test specimens to be imaged by means of backscatter electrons without any sort of preparation and free from artefacts with a quality not hitherto achieved. This is achieved by means of a finely meterable and pre-ionisable gas flow which flows around the test specimen surface in a pinpointed fashion in the test specimen chamber, in which it discharges the charges on the surface of the test specimen which cause image interference, and is finally once again extracted. A constant vacuum which is favourable for the test specimen is created in its immediate vicinity by means of a fine-metering valve and an electronic control without the vacuum being reduced to the same value in the entire test specimen chamber. By using such a system it is also possible for small living organisms to be imaged alive in the scanning electron microscope.

Title: Device for the remotely controlled guidance of armoured combat vehicles
Inventor: ABELS FRANK
IPC: F41G5/24
Filed: 1984-02-07
Abstract: A device for the remotely controlled guidance of armoured combat vehicles, in which a command vehicle accommodating the crew is allocated an unmanned armoured combat vehicle in which the main weapon together with the targeting and aiming apparatuses are arranged and which accommodates the ammunition supply. The command vehicle and armoured combat vehicle are coupled to one another via a directional radio link so that the armoured combat vehicle can be guided by the preceding command vehicle. To this end, the respective movement-guidance data are recorded in the command vehicle and are transmitted via the directional radio link to the armoured combat vehicle, where they are stored. The speed of the armoured combat vehicle and its distance from the command vehicle are continuously measured, and the stored movement-guidance data are supplied to the movement-guidance system of the armoured combat vehicle, as a function of said measurements, at that instant at which it passes the point at which the movement-guidance data have been recorded by the command vehicle. For remote control of the fire-control system, the image from the targeting apparatus is transmitted over the directional radio link to a monitor in the command vehicle. In the same way, aiming and firing commands are transmitted via the directional radio link to the fire-control system in the armoured combat vehicle.

Title: Spectrometer
Inventor: RITZL HERMANN DR ING
IPC: G01J1/42
Filed: 1984-06-15
Abstract: A spectrometer which consists of a light source, which excites a specimen, and a monochromator whose intensity values detected at the exit slit are further processed in a computer in conjunction with the associated wavelength values is equipped, in order to achieve a large measurement range and a high measurement accuracy, with two secondary electron multipliers and a beam splitter which feeds the second secondary electron multiplier with only a small fraction of the radiation emerging from the monochromator. Via an A/D converter, an electronic switch switches through to the computer the output of that secondary electron multiplier whose output signal is inside the level range that can be evaluated. The computer drives the monochromator repeatedly through the measurement range and stores the measured values individually, which are then processed to form mean values.

Patent DE-3435906-A1 (DE)
Inventor: BAUS HEINZ GEORG
IPC: B29C63/02
Filed: 1984-09-29
Abstract: A method and an apparatus are described for processing and applying a protective foil to a flat sheet made, more particularly of a thermoplastic synthetic material. The protective foil is used to protect the relatively soft surface of the sheet but, during further processing, difficulties arise in that parts of the surface must be freed of protective foil. In order to protect at least certain areas of the sheet as long as possible from external effects or damage, there is provided a protective foil which, before it is applied to the sheet or to a strip from which the sheet is subsequently produced, is formed with perforations. During further processing of the sheet, the parts of the foil corresponding to the areas of the sheet that are to be freed, are removed and the remainder is protected by the remaining parts of the protective foil.
