Title: Device for joining large-diameter pipes
Inventor: MARTINEZ LOUIS GEORGES
IPC: F16L1/09
Filed: 1984-02-10
Abstract: The invention is based on a device which can be moved within pipes (1), which device is provided with supporting struts (8) which can be pivoted in a vertical plane and via which the device can be braced within the pipe (1) in order to be able to absorb tensile forces for drawing a further pipe (2) into the sleeve of the ready-laid pipe (1). As a tension device, a hydraulic cylinder (26) engages on the lower part of the supporting strut (8). During laying of specific types of steel pipes, high tensile forces are necessary which in turn require stronger bracing of the vertical supporting struts (8) in the last pipe (1) laid, as a result of which the pipe experiences deformation. In order to avoid such deformation and at the same time to allow higher bracing forces to be applied, in addition, side struts (36) are provided which are arranged in pairs, can be pivoted horizontally and have guide parts (43) which are fitted at their outer ends such that they can pivot and can be braced laterally in the pipe (1) by means of a hydraulic expanding cylinder (40) which engages on them. The side struts (36) are provided with additional tension cylinders (44) in order to draw in the pipe (2) which is to be laid. <IMAGE>

Patent DE-3427611-A1 (DE)
Inventor: BILLE JOSEF PROF DR
IPC: H01L21/027
Filed: 1984-07-26
Abstract: An energy (i.e. laser) beam directed to a photoresist layer is scanned in a first direction through lines progressively displaced in a second coordinate direction. In this way, stripe areas of a wafer are exposed sequentially in a first direction with a thickness dependent upon the size of the laser spot focussed on the beam. The beam scanning rate is adjustable to obtain a time coincidence between the occurrence of markers in a computer and the scanning of a particular position in each line. The beam is modulated during the scan to inscribe a pattern on the layer. The beam is focussed on, and reflected from, the photoresist layer. The reflection is used to maintain the focussing of the beam on the layer by adjusting individual elements in an active mirror in accordance with the reflected beam characteristics. The beam may be split into a plurality of beams displaced from one another in the first direction by providing associated pairs of spherical facets in a lens system and directing portions of the beam between the facets in each pair. Such beams are synchronously scanned to increase the scanning frequency. A second beam with different characteristics than the first beam may be scanned asynchronously (e.g. a reduced speed) relative to the first beam and may be focussed on the photoresist layer in a manner similar to that described above. Light reflected in the second beam from the layer is used to adjust the characteristics of the individual elements in the active mirror so as to maintain the beam focussed on the photoresist layer.

Title: Method and device for accurately evaluating the measurement signals determined from a capacitive protective fence
Inventor: KUPEC PETER DR ING
IPC: G08B29/18
Filed: 1985-07-23
Abstract: The protective fence, having a number of wire electrodes (DE), exhibits an evaluating circuit arrangement (ASA) arranged in an electronics cabinet. Before it is taken into operation, this circuit arrangement is subjected to a temperature cycle (-20 DEG C to +50 DEG C) in a burn-in process. During this process, the input circuits (ESK1 to ESKi) of the evaluating circuit arrangement (ASA) are supplied with a constant measurement signal. For the changes in measurement values occurring during this process, an individual temperature coefficient is determined and stored for each input circuit (ESK1 to ESKi). During normal operation, the temperature in the electronics cabinet is continuously measured. Due to the individual temperature coefficients, the temperature function is determined for each input circuit (ESK1 to ESKi) and the respective measurement signals received are correspondingly corrected. <IMAGE>
