Title: Method and arrangement for compensating for the tilt axis error in surveying instruments
Inventor: FEIST WIELAND DR ING
IPC: G01C25/00
Filed: 1987-05-27
Abstract: The invention relates to a method and an arrangement for compensating for the tilt axis error in electronic theodolites and tachymeters for measurements in a telescopic system in which the pure tilt axis error is directly compensated for by means of an inclination measuring device for measuring the slant of the vertical axis without needing a microprocessor for calculating the correction values with respect to tilt axis error for the measured horizontal directions. This is achieved by the zero-point error of the inclination measuring device being set by calibration of an adjusting element in such a manner that the zero point error is proportional to the pure tilt axis error measured by means of a test device. The inclination measuring device, comprising a measuring device for the slant of the vertical axis, an inclinometer and an adjusting element are arranged in a support element carrying the telescope. The adjusting element is preferably a second screw on which a scale or an index is arranged. <IMAGE>

Title: Method for scraping pipelines run underground and scraper for carrying out the method
Inventor: WIEDEMANN ANTON DIPL ING
IPC: F16L55/48
Filed: 1987-07-09
Abstract: On scraping a pipeline run underground between a first position and a second position remote from the latter, a gyroscope-supported inertial navigation system (11), a recording device (15...19) and a power supply source (20) are carried along with the scraper. The space coordinates of the scraper are picked up by the navigation system (11) during its movement along the pipeline and are recorded in the recording device. The recorded space coordinates or their changes along the pipeline are related to the space coordinates at the first and second positions and, finally, the spacial run of the pipeline between the first and second positions after the scrapping is determined by evaluating the recorded space coordinates and their changes. The scraper can be constructed as a chain of links, the links of which are connected to one another via hinges. The electrical components (11...23) of the navigation system and of the associated recording device can be distributed over a number of links in order to minimise the core diameter of the scraper. <IMAGE>

Title: Method and equipment for setting up and generating a spatial orthogonal measuring network, especially for setting up dimensions in the framework of structural surveys
Inventor: KORTE MICHAEL H DIPL ING
IPC: G01C15/00
Filed: 1988-08-12
Abstract: In the method for setting up and generating a spatial orthogonal measuring network, at least one intersection plane (D) is generated from a light beam (L), running at right angles thereto. From this intersection plane (D), at least one plane segment (P1, P2) running at right angles thereto is likewise derived, running parallel to the light beam (L). The light beam originates from a light source (1) set horizontal, is brought coaxially into a pentaprism (2), and the latter generates by means of rotation a 90@ deflection of the light beam (L) with the formation of an intersection plane (D), the light beam being led into at least one further pentaprism (3a or 3b), in order thus to generate, by means of a further deflection by 90@, plane segments P1 and P2 which run parallel to the light beam (L). <IMAGE>
Patent DE-3828852-A1 (DE)
Title: Ventilating device
Inventor: KRAGE HEINRICH DIPL ING
IPC: E06B7/02
Filed: 1988-08-25
Abstract: Devices of this type have a relatively unfavourable ratio of volume rate of flow to overall volume, in particular to the overall height of such a device, so that with a selected overall height the air output is either unsatisfactory or with a sufficient volume rate of flow the actual window area intended for the passage of light is restricted. A solution to the problem is achieved in that the overall volume between two transoms is optimally utilised and the distance of the transoms from a [lacuna] is determined merely by the fluidically conditioned air passage area, brought about by a multi-function housing which is at the same time also a volute for a fan impeller and a weather protector. The ventilating device is used chiefly in window and facade construction. <IMAGE>

Patent DE-3842702-A1 (DE)
Inventor: SCHLIPFENBACHER REINER DIPL CH
IPC: G01N33/558
Filed: 1988-12-19
Abstract: The reaction is preferably an antibody-antigen reaction. On a base layer (2) there are test zones (21 to 25) which have capillary activity and are arranged side by side and form a liquid transport distance (30) along which a liquid flows, driven by capillary forces. During this, a specific detection reaction takes place and leads to a species characteristic for the required analysis, and this species is detected in a detection zone (26). In order to provide a test strip which is easy to handle and can be produced at low cost and has a start zone which needs to be only briefly immersed in the sample and then gradually releases the absorbed sample liquid in such a way that the successive zones which form the actual functioning region of the test strip are adequately and reproducibly supplied with liquid, it is proposed that the start zone (21) be composed of a non-swelling bonded fabric with a water-insoluble binder. <IMAGE>

Title: Method and arrangement for welding thin sheet
Inventor: BUEDENBENDER BERND
IPC: B23K26/24
Filed: 1989-01-18
Abstract: In the welding of thin sheet, preferably by means of a heating laser beam, expensive machining of the edges, as required in butt welds, is to be avoided, as is local doubling of the thickness of the joined sheets, occurring in the welding area through overlap of the sheets, in combination with the edged steps occurring here. This object is achieved by the sheets to be joined being placed one on top of the other in such a way as to overlap one another with narrow marginal strips remaining and by the heating laser beam being passed across this marginal area, which is reduced in its thickness by means of pressing tools immediately after the heating preferably above the melting point. Rollers have proved successful for carrying out the pressing operation. When passing through the still hot overlap area, the rollers, through the rolling gap formed between them, reduce the thickness of the welded overlap area from double the sheet thickness to a smaller thickness, preferably down to the single sheet thickness.
