Title: Process and apparatus for repairing sewer pipes
Inventor: ROGALSKI GUENTER
IPC: F16L55/179
Filed: 1987-09-10
Abstract: The invention relates to a process and to an apparatus for repairing a buried sewer pipe which consists of stoneware, concrete or the like and into which at least one inflow opens. Sewer pipes of this type are either exchanged or repaired if they are damaged. However, it has only been possible, up until now, to repair sewer pipes with a relatively large internal diameter. In the case of sewer pipes with a small internal diameter, it has not been possible, up until now, to shut off the inflows and thus prevent the supply of sewage during the repair procedure. In order now also to be able to repair sewer pipes which consist of stoneware, concrete or the like and have a diameter of from approximately 150 mm to 500 mm, the invention proposes that a shut-off bubble (23) be transported, by means of a carriage (4) which can be displaced in the sewer pipe (1), from a sewer manhole (2) as far as the respective inflow (3) and there be moved, by a pivotable gripper (21), into the inflow (3), being inflated in a sealing manner and secured, and that the opening (46) be produced in a drawn-in, hardened inner liner (40) by a milling unit (41), which can be positioned on the carriage (4), and the shut-off bubble (23) subsequently be deflated and removed. <IMAGE>

Patent DE-3737323-A1 (DE)
Title: Manhole cover impermeable to surface water and backwater
Inventor: EICHELMANN HORST DIPL ING
IPC: E02D29/14
Filed: 1987-11-04
Abstract: Manhole covers with a seal against surface water or backwater have two functions to perform. They have to absorb the traffic loads and they have to soundly seal the manhole. However, this is only accomplished when the locks of the cover are properly operated. If this is not the case, the mounting of the cover is not safe for traffic. If the cover seal is arranged in the cover periphery and the sealing surface is made "negative" in the frame, i.e. in an undercutting manner, a vertical force component is obtained which presses the cover downwards onto the seating. This ensures that the cover is always in a position which is safe for traffic.

Title: Method for quasi-simultaneous measurement of changes in length and/or width and/or thickness on elongated material samples, and device for carrying out the method
Inventor: KLEINHUBER HARALD
IPC: G01B11/16
Filed: 1988-06-04
Abstract: The method is used for quasi-simultaneous measurement of changes in length and/or width and/or thickness on elongated material samples of preferably rectangular or round cross-section, which are respectively clamped at the end in a clamping device and are subjected therein, in particular, to tensile loads. The material sample is provided on its front, preferably wider end with at least two markings which are arranged in the longitudinal direction of the sample, can be detected optically and are scanned by a light beam, which can be deflected in a linear direction, and sweep over the material sample in its longitudinal direction, in order to determine their mutual separation. The light reflected from the markings is collected by a photodetector, and the separation of the markings is determined from the temporal separation of the signals detected by the photodetector, taking account of the rate of deflection of the light beam and of the geometrical arrangement. In terms of time, before or after its scanning path, which extends in the longitudinal direction over the material sample, the light beam traverses a mirror arrangement which deflects the scanning direction of the light beam into a direction orthogonal thereto, and thus once again onto the sample, so that the light beam scans the material sample alternately in the longitudinal and transverse directions. Arranged behind the sample is a reflection screen which, given scanning of the material sample in the transverse direction, [lacuna] the light of the light beam passing by the sample ...

Title: Process and apparatus for the rigid-plastic extrusion of ceramic products of large cross-section with a relatively small extruding screw conveying cross-section
Inventor: THOMAS HANS
IPC: B28B3/22
Filed: 1988-09-06
Abstract: The invention relates to a process and an apparatus for the rigid-plastic extrusion of ceramic products of large cross-section with a relatively small extruding screw conveying cross-section. The aim of the invention is to extend the range of applications of extruders, so that the extrudable melt strand cross-section can approach the cross-section of the extruding screw. The aim of the invention is achieved by the melt stream produced by the extruding screw being divided into at least three annular melt substreams and by these substreams being forcibly deflected outwards by about 45@, the melt substreams having a volume ratio of 1 : 2 : 1.   The apparatus according to the invention is characterised by a manifold insert, which encloses the extruding screw, of a conical design at the end, and is arranged centrally in a compression chamber opening out to twice the diameter of the extruding screw. To achieve optimum flow conditions of the melt, the transitions from the manifold insert, compression chamber and extruding channel, as part of the compression chamber, are made such that they are tangentially radial. <IMAGE>

Abstract: In order to test aspheric surfaces or aspheric wave fronts, the collimator (8) - the generator which generates the test wave - of the interferometer is displaced relative to the test sample (12) and interferograms are electronically recorded in various positions of the collimator by means of an image sensor (5) and stored as optical path differences between the test beam and the reference beam for the individual image points of each interferogram. The relative position between the collimator (8) and the test sample (12) is also measured with great accuracy. 
<??>Subsequently, the interferometrically measured optical path differences are compared with theoretical optical path differences which are computed for the various positions of the collimator or determined by calibration, and the aspheric shape of the wave front of the test sample as a whole is computed therefrom. In this case, the measured values which are obtained for the various partial regions of the test sample and in which the test wave impinges substantially normally on the surface of the test sample are integrated over the entire surface of the test sample.
