Title: Interior-surface protection for a pipeline
Inventor: MUECHER HORST
IPC: F16L58/18
Filed: 1987-08-24
Abstract: The interior-surface protection (1) for a pipeline (20) comprises a protective-profile shell which extends over the inner wall of said pipeline and consists of plastic, stainless steel, concrete with a synthetic resin dispersion, glass fibre reinforced plastic or the like. For transportation and mounting reasons, said protective-profile shell is subdivided into a plurality of protective-profile lengths (14) which are arranged axially one behind the other. Two neighbouring protective-profile lengths (14 and 14') are not fitted together until within the pipeline (20), the butt joint (24) located between them being sealed by an axially rigid, sleeve-like joint seal (8). The latter is fastened, such that it is secure with respect to axial displacement and seals radially, on the axial end of one protective-profile length (14) before the two protective-profile lengths (14 and 14') are moved together. In this arrangement, that part of the joint seal (8) which still projects freely beyond said protective-profile length (14) in the axial direction exhibits a radial internal diameter which is smaller than the radial external diameter of the protective-profile length (14') which is still to be mounted. It is only when it is in its end mounting position that said protective-profile length (14') is also radially outwardly enclosed by the joint seal (8) in an elastically sealing manner. The interior-surface protection (1) according to the invention is preferably used for the corrosion-resistant lining of pipelines (20) which have already been laid and have already corroded on the inside, in particular of waste-water lines consisting of cement-bound materials. <IMAGE>

Title: Measurement converter with a capacitative sensor
Inventor: SCHULZ WINFRIED DR ING
IPC: G01L9/12
Filed: 1987-10-29
Abstract: In measurement converters having capacitative sensors, the influence of stray and load capacitance becomes especially noticeable when, because of a very compressed constructional shape of the capacitative sensor, the changes in capacitance which depend on measured values are relatively small. In order to give a linear dependence of capacitance change on mechanical position to a measurement converter with a capacitative sensor of spatially compressed constructional shape, a conductive layer is provided in the end region of a stable planar electrode (2) and a diaphragm-like electrode (4) arranged opposite this and insulated from it, and an amplifier (17) connected to the electrodes is designed as an impedance converter. The output (18) of the amplifier (17) is galvanically connected to the conductive (9) layer.   The measurement converter is suitable for manufacture using miniature construction techniques. <IMAGE>
Patent DE-3737672-A1 (DE)
Inventor: SCHANZ MANFRED
IPC: B23Q3/10
Filed: 1987-11-06
Abstract: A clamping device (1) (Fig. 1) serves to clamp a workpiece (3) having column or coordinate bores (2) in position. It serves in particular to clamp die plates in position. Clamping elements (5) of the clamping device (1) engage in these column bores (2). By an axial movement, the clamping elements (5) can be expanded roughly radially and concentrically by means of taper surfaces. In the process, the axial clamping movement is coupled to the radial expanding movement so that the clamping element is also displaced in the axial direction during the clamping operation. The clamping elements (5) are mounted on a base clamping plate (4). Provided on the underside of the base clamping plate (4) are locating projections (20) which engage in workholding slots (21) or bores of a machine tool table (6) in an accurately fitting manner. The clamping device (1) results in repetitive, accurate location of workpieces (3) clamped there, so that there is a considerable reduction in the setting-up times with at the same time high positioning accuracy, especially in mass production. <IMAGE>

Title: Apparatus for sampling electrical signals
Inventor: GEHRI ANDRE
IPC: H01F27/06
Filed: 1987-11-13
Abstract: The apparatus for sampling electrical signals in the primary circuit of a busbar has a housing (3) which surrounds the busbar (2) in a positively locking manner only in the region of the edges (4) and is pressed here, in this region, against two bolts (7) which are plugged into holes (8) in the busbar (2), the latter being clamped in between the housing (3) and a flange (10), which can be mounted on the housing by means of screws (11). In the housing (3), the bolts (7) are held, such that they cannot be displaced, in a housing cover (9), which is centred on the housing (3), by means of webs (12) engaging over them. The central part (5) of the housing (3) is constructed in a circular shape in the region of the busbar (2) so that a free space (6) remains for air circulation. In this way, the apparatus withstands severe mechanical loads, while the heat transmission is reduced to a minimum. <IMAGE>

Title: Method and apparatus for the bundling of bales of stalk material
Inventor: BERNER DIETRICH DIPL ING
IPC: A01D90/08
Filed: 1987-12-14
Abstract: In the method according to the invention, in each case at least two bales are lined up with longitudinal side faces bearing against one another in pairs to form a bale row (36). At least two bale rows (36) lined up in succession are connected to one another by means of at least one band tie-round (56) engaging transversely over the free longitudinal side faces (2) of the bales, to form a bale group (54). Finally, at least one further bale group (54) bearing against the preceding bale group (54) are connected to one another by means of a band tie-round (56) adjoining the band tie-round (56) of the preceding bale group, to form a bale bundle (58). The loading and transport operation for even small high-pressure bales can thereby be mechanised and at the same time an easy handling of the individual bales at the place of use is guaranteed. <IMAGE>
Patent DE-3743414-A1 (DE)
Inventor: ASANO SHINYA
IPC: B41J35/22
Filed: 1987-12-21
Abstract: In a selective printing apparatus of the kind in which an error can be corrected by overtyping via an erasure medium (e.g. a lift-off or obscuring correction ribbon), the erasure medium is indexed by a predetermined small movement between successive multiple erasure typestrokes, the magnitude of the indexation being automatically determined in response to a sensed condition. As described, the indexation is vertical and is effected by controlling the ribbon-lift mechanism in response to     (a) the nature of the erasure medium (b) the dimensions of the character to be erased from within a single character set  or   (c) the dimensional characteristics of a character set per se from within a selection of character sets.   <IMAGE>

Patent DE-3806742-A1 (DE)
Title: Centrifuge with improved discharge arrangement
Inventor: NORDSTROEM TORBJOERN
IPC: B04B11/02
Filed: 1988-03-02
Abstract: In order to maintain a low level in the separation chamber (26) of a centrifuge rotor out of which fluid is intermittently pumped to a reception point outside the rotor, the flow of fluid out of the separating chamber (7) to the separating chamber (26) of the rotor has hitherto been limited and at the same time a limited amount of fluid has been allowed to leave the separating chamber (26) through a calibrated outlet. According to the invention, the calibrated outlet (37,38) of the discharge chamber (26) is closed, with a valve (35) which can be actuated intermittently, when fluid is pumped out of the discharge chamber (26) to the receptacle point outside the rotor. <IMAGE>

Title: Adhesive rewind limiter (stop) for films having a protective cartridge (cassette)
Inventor: STROBEL FRIEDRICH
IPC: G03B17/30
Filed: 1988-03-15
Abstract: In this adhesive rewind limiter, a resilient tongue (1), having a V-shaped predetermined kinking (bending) point (2), can be stuck on by means of two self-adhering surfaces (3, 4), located at the ends of the resilient tongue (1), to the start of a film (6). It must be ensured in this case that the V-shaped predetermined kinking point (2) is aligned so as to point towards the protective cartridge (5), in such a manner that in this arrangement the adhesive rewind limiter is, on the one hand, pressed flat against the start of the film (6) while kinking the resilient tongue (1) at the predetermined kinking point (2), when the film is wound onto a take-up spool, and thus does not impede the further functions of the camera or the film, while, on the other hand, when rewinding the film and after the start of the film (6) has disengaged from the take-up spool, the resilient tongue (1) springs away from the start of the film (6) and then becomes so bulky that it does not fit through the slot (7) of the protective cartridge (5) and the start of the film (6) can thus still be gripped. It is expedient, for easier detachment of the adhesive rewind limiter from the start of the film (6), to leave projecting a non-adhesive piece of material in continuation of the self-adhering surface (4) which faces the start of the film (6), which piece of material can be gripped easily and therefore serves as grip piece (8). For easier recognition, up to which frame a film, which has been started and taken out of the camera, has already been exposed, the visible surface (9) of the resilient tongue (1) and the self-adhering surfaces (3, 4) ... can be written upon ...

Title: Device for optical measurement of a path length or a change in path length
Inventor: BOSSELMANN THOMAS DR
IPC: G01D5/26
Filed: 1988-05-18
Abstract: In a measured value pick up (2), the light (14) emerging from an optical fibre (4) is reflected after passing over the path length (x) to be measured and recoupled into the optical fibre (4). The emerging light (14) contains two spectrally differing components which are reflected on different surfaces in the measured value pick up (2). According to the invention, a Fabry-Perot filter (6) is arranged in the measured value pick up (2) for the purpose of splitting the light (14) into two light components (16 and 18) having mutually interleaved band spectra. For the purpose of separate measurement of the two light components (16 and 18) coupled back into the optical fibre (4), in a particularly preferred embodiment an analyser device (50) is provided with a rotatably arranged Fabry-Perot filter (52). The interleaving of the spectra of the two light components (16 and 18) can be used largely to suppress the influence of the temperature dependence of the spectal transmission characteristics of the optical fibre (4) on the measurement result. <IMAGE>

Title: Process and apparatus for producing a packaging unit by winding a foil web round the material to be packaged
Inventor: ORTH UWE
IPC: B65B11/02
Filed: 1988-06-13
Abstract: The subject of the invention is a process and an apparatus for the production of a packaging unit by winding a foil web round the material to be packaged. In the process, the foil web (23) drawn off from a stock roll (8) is applied with its front end (28) to the material to be packaged (29) and is wound around the material to be packaged (29) as a result of relative rotation between the material to be packaged (29) and the stock roll (8). In order to avoid applying an additional turn solely for fixing the first turn of the foil web, during the first wind-round the front end (28) of the foil web (23) is held against a suction pipe (13) by frictional connection and, even before the termination of the first turn, the front end (28) of the foil web (23) is fixed to the suction pipe (13) by a suction effect. To generate the suction effect on the suction pipe (13), a device (27) generating a vacuum is provided. After at least a single covering by the foil web (23), the suction pipe (13) is drawn out of the already wound foil web (23) in parallel with the winding axis, before the winding operation is concluded by applying further turns of the foil web. <IMAGE>

Title: Plug socket cover having a plug socket pot
Inventor: TISCHNER HANS
IPC: H01R13/504
Filed: 1988-07-19
Abstract: The invention relates to a plug socket cover having a plug socket pot, in the case of which a suitable material need be used only for those plug pin bushings which are highly stressed electrically/thermally, while the remaining part of the cover need not satisfy this requirement, that is to say it is therefore also more cost-effective as a rule. Three inventions can be used selectively in order to solve this problem. In the case of the first invention, only the plug socket base is produced from the technically high-quality material and is inserted into the cover as a separate part; in the case of the second invention, only the plug pin bushings are lined with this material, and in the case of the third invention, the problem is solved by a two-material spraying process, only the region of the plug pin bushings expediently then being sprayed with the high-quality material.

IPC: H01T4/06
Filed: 1988-12-23
Abstract: Isolating strips for the facultative connection of electrical lines to contacts and to isolating connectors which separate the mutually touching contacts with an isolating tongue are known. An overvoltate protection connector is also known in this context. In order to be able to match individually the overvoltage protection to the circuits which are respectively present and are connected to the isolating strip, to be precise while maintaining the advantages of quick, easy handling of such switching connections, the invention provides that the overvoltage protection connectors be designed in the manner of an isolating connector of such isolating strips (1) and as four-pole networks, two terminals of the four-pole network being provided as contacts on one side and the further two terminals of the four-pole network being provided as contacts on the other side of the isolating tongue (17) of the overvoltage protection connector. The contact pairs of the overvoltage protection connector match the contact pairs (3, 4) of the isolating strip and are dimensioned such that when the overvoltage protection connector is plugged in, its contact pairs are positioned between two contact pairs of the isolating strip and make an electrical contact thereto. The overvoltage protection connectors are inserted from the same narrow side of the isolating strip as the isolating connectors into the said isolating strip, and hence assume their inserted position. Inside the respective overvoltage protection connector there are housed means of overvoltage protection which are electrically connected to its contacts. Out of the overvoltage protection connector there projects its earth terminal, or its earth terminal is accessible as a terminal. <IMAGE>
