Patent DE-3724751-A1 (DE)
Inventor: MAURER PETER
IPC: D06B23/06
Filed: 1987-07-25
Abstract: The method for the production of partial warps wound on warping beams or sectional beams, or warps of synthetic filament yarns wound on warp beams, which are completely stretched and sized, consists of sizing a group of parallel synthetic thermoplastic filament yarns, the filaments of which are not completely stretched, in a sizing zone, predrying the sized yarns in a heated predrying zone, subjecting the predried sized group of yarn by final drying in a heated final drying zone, and finally winding the dried group of yarns on warping or (sectional) beams, while the filaments of the filament yarns are stretched jointly and simultaneously in the predrying zone. The stretching occurs preferably between rolls (5, 6) assigned to the sizing zone and rolls (10) assigned to the final drying zone. The method may be carried out with conventional, at most slightly modified sizing machines and it furnishes very uniform partial warps or warps. In particular the filaments of the filament yarns are stretched very uniformly. In addition, a twisting or twist-replacement treatment of the filament yarns prior to sizing may be eliminated because warps are obtained, the filament yarns of which have sufficient cohesion for further processing and a high density of their filaments.

Title: Large-area high-energy laser mirror and method for producing such a mirror
Inventor: LINDNER FRIEDRICH DR
IPC: G02B5/08
Filed: 1988-03-24
Abstract: A large-area high-energy laser mirror (11) and a method for producing such a mirror (11) are based on the fact that plate-shaped segments (16), preferably cut from commercially available silicon wafers, are grouped, as far as possible without leaving gaps, on a support plate (15). Since it is not possible to polish mechanically the effective mirror surface (20) beyond the butt joints (17) of the segments, the butt joints (17) are welded to each other over the entire material thickness of the segments (16) by laser or electron beam welding before the mirror surface (20), which is now closed, is polished, if necessary after any projecting welding seam beads (21) have been removed mechanically. <IMAGE>

Patent DE-3818215-A1 (DE)
Title: Process for the catalytic oxidation of a hydrocarbon/air mixture and apparatus for this purpose
Inventor: DAHLHOFF BERND DR ING
IPC: B01D53/30
Filed: 1988-05-28
Abstract: Previously known processes of catalytic oxidation are not able to deal with highly varying loads of the mixture containing hydrocarbons to be treated. Whenever highly varying loads of the said type occur processes other than catalytic oxidation are therefore used. It is therefore proposed according to the invention that, depending on the result of a continuous load analysis or on the exhaust gas temperature of the catalyst on the inlet side, enough external air is always added so that the catalyst is run at the functioning temperature and the sought-after exhaust gas values are achieved. This can be achieved by controlling the hydrocarbon/air mixture used and/or by supply or removal of heat.
Patent DE-3818419-A1 (DE)
Title: Filling apparatus for liquid substances
Inventor: SALMEN ARMIN
IPC: B65B3/26
Filed: 1988-05-31
Abstract: In known filling apparatuses for liquid substances, it is necessary to use a multiplicity of components which are moved and which are sometimes produced to high accuracy. The disadvantages occurring thereby, such as, for example, high prime costs, high weight, pronounced noise generation and wear, do not occur in the new apparatus. The new apparatus makes it possible, by the use of an electronic control, to obtain a desired filling level and, at the same time, to do away almost completely with moving parts. So that the desired filling level can be set, 2 electrodes are introduced, together with the filling tube, into the container to be filled. In order to allow universal use, the electrodes can be mounted so as to be vertically adjustable. The filling apparatus is suitable for the filling of liquid substances having some electrical conductivity into open or closed containers, in which a specific filling state is to be achieved.

Title: Method and apparatus for fabricating a pipe bend
Inventor: EURISCH HANS
IPC: B23K37/053
Filed: 1988-06-28
Abstract: The two component shells of a pipe bend are butt welded or brazed to one another at their longitudinal margins. To this end, the component shells are inserted in shell receptacles and are trimmed lying inside the shell receptacles. Then the shell receptacles are brought closer to one another while very narrow brazing or welding gaps are formed. After this an expanding-mandrel unit is placed between the component shells and expanded so that the longitudinal margins of the component shells are pressed against the longitudinal margins of the shell-receptacle surfaces. Welding is then carried out.
Patent DE-3828664-A1 (DE)
Title: Tube holder
Inventor: KIRION JAKOB
IPC: B65B43/54
Filed: 1988-08-24
Abstract: The tube holders used hitherto required, for the processing of tubes of oval cross-section, either a manual feed or complicated feed systems, so that the tube body could be aligned exactly with the filling nozzle. The collar-like arrangement of spring elements (9) ensures exact centering for oval tube bodies too and, furthermore, also a deformation of the filling end of the tube into a circular cross-section, so that an automatic feed of the tube bodies, without prior alignment, is possible. <IMAGE>

Filed: 1989-03-02
Abstract: An accelerometer is described which has a housing (10), a test mass (15) which contains a coil (18) and is supported inside the housing (10) in such a way that it can be displaced along an axis of displacement from a zero position by an applied force, and a sensing arrangement which has electrodes on a fixed electrode holder (33) and determines a displacement of the test mass (15) along the axis of displacement and supplies an electric signal representing the applied force. The test mass (15) is mounted on an arm (20) which is attached to a shaft (21) which is rotatably supported by pivot bearings (22 and 23). Each bearing (22, 23) has a rotatable bearing part (26) and a fixed bearing part (28) with a magnet (29), and there is a magnetisable flowing medium (30) located between the bearing parts (26 and 28). This arrangement supports the test mass (15) in such a way that by virtue of the bearing arrangement it can execute a virtually frictionless movement under the applied force. The magnetisable flowing medium (30) and the magnets (29) therefore supply permanent magnetic levitation forces which act between the bearing parts (26 and 28). <IMAGE>
