Patent DE-3829260-A1 (DE)
Title: Plasma-coating chamber with removable guard screen
Inventor: MATENTZOGLU NIKOLAUS
IPC: H01J37/32
Filed: 1988-08-29
Abstract: For heating objects (4), which are to be subjected to PVD coating, for example with titanium nitride, to the required process temperature, indirect heating is proposed. At the start of the process, a screen is arranged between the objects and the cathodes (5) which supply the energy and are vapourised by an electric arc, and the screen is removed after the process temperature has been reached. The screen can have the shape of a hood, placed over the objects or it can consist of suspended lamellae which, when not in use, are pushed together in a corner of the coating chamber to give a pack which does not impede the plasma flow to the objects. In this way, the macroscopic particles which are ejected from the cathodes, particularly at the start of the process, and have not been converted into the plasma state and otherwise reduce the surface quality of the coating, are kept away from the objects. <IMAGE>

Title: Process for encapsulating a vessel in foam
Inventor: MEIKE KLAUS
IPC: B29C44/12
Filed: 1988-12-23
Abstract: A vessel (4), in particular a service water tank, is to be surrounded with an insulating foam (7), it being intended to prevent foam from escaping at separation joints, to avoid the use of a release agent in the foaming mould (1) and to provide the finished foam-encapsulated unit with a fully enclosed sheath. For this purpose, a film bag (2) is placed into the foaming mould (1), the vessel (4) is introduced with a spacing on all sides and, after closing the mould, the remaining cavity is filled with insulating foam (7). The film bag (2) thereby comes to lie on the inner walls of the foaming mould (1) and forms a fully enclosed outer skin. <IMAGE>

Title: Air pressure-reduced or vacuum transport tube system (ART transport system), jet trains, track changing and transfer systems, jet train stations, jet train transport lines
IPC: B60F1/02
Filed: 1989-02-17
Abstract: The aeroplane is the main means of transport for large distances. It has particular advantages, e.g. speed, independence of fixed lines but also serious disadvantages such as environmental damage, noise pollution, high costs for airports and flight insurance, increasing numbers of transport accidents etc. The object of this invention is to develop a new terrestrial vehicle (jet train) which can achieve in particular on the ground speeds which are similar to or the same as those of aeroplanes without the serious disadvantages substantially outlined above. The object is achieved by a new kind of transport tube system (ART system) which is in particular airtight and in whose interior vehicles (jet trains) move in tubes or the like which are partially or completely evacuated of air and to whose shape the vehicles are matched, the said vehicles being guided by magnets, or air cushions or moving conventionally at high speeds driven by means of conventional drives with rockets or by means of magnets or newly developed air circulation rocket systems with special devices for changing track and transfer devices and in particular jet train stations and generalised transport lines for the ART transport system. The application and the use of this invention will be worldwide, in particular thanks to the advantages that the jet train can be propelled along in the air vacuum tubes at a high speed independently of the weather and with a high degree of safety and low energy consumption.

Patent DE-3932831-A1 (DE)
Inventor: GLEIM GUENTER
IPC: G11B7/09
Filed: 1989-09-30
Abstract: A light beam which scans the data on an optical recording support, generates an r.f. signal in the recording and/or playback device. As the r.f. signal is interrupted when the light beam leaves a data track, the detector circuit recognises from the r.f. signal level whether the beam is passing from one data track to the next. As the interruptions in the r.f. signal can also be caused by dirt, damage or errors on the recording support, it is impossible to be certain whether such an interruption has been caused by a track change or by dirt, damage or errors on the recording support. In order to recognise track changes reliably, the detector circuit does not generate a signal indicating a track change until the r.f. signal (HF) is below a first predetermined threshold (R1) and at the same time a track error signal (TE) is above a second predetermined threshold (R2). Detector circuit which recognises when a scanner leaves a mark or data track, e.g. in CD players, video record players, DRAW-disc players and magneto-optical recording and/or playback devices.

Title: Welding machine for waterproof films - has adjustably heated wedge between overlapping edges of films and vibrating heated pressure roller then applied to the overlap
Inventor: FROEHLICH DIETER
IPC: B29C65/00
Filed: 1989-12-06
Abstract: Appts. for welding together overlapping waterproof films heats their areas concerned and presses them together using vibrations to provide the pressure. The equipment seals films for use on a dump or on a flat roof, it inserts a heating wedge between the two overlapping edges of film. The tool contains an adjustable heating element and is set to reach the desired temp. The two films are then drawn under a pressure roller. This roller applies both its own weight and also vibrations produced by a rotating eccentric acting on an outer circumference in the roller. The vibrations are set to the resonance frequency of the appts. so as to have optimum effect. ADVANTAGE - The equipment does not produce corrugations in the welds. It does not simply use the weight of the appts. or the films.
