Patent DE-3534965-A1 (DE)
Title: Fixing points of pipelines
Inventor: SCHOEDLER REINHARD
IPC: F16L59/13
Filed: 1985-10-01
Abstract: Fixing points of pipelines for hot or cold media are constructed in the form of mounting discs which are anchored in concrete, sand, gravel (grit, shingle), rock (stone) or earth. The pipelines consist of a metallic inner pipe (14), an outer pipe (16) made of plastic or Eternit and an insulating material (26) which fills the cavity between the pipes. The mounting disc (10), which projects out of the pipeline in the radial direction and is arranged coaxially at a distance from the inner pipe (14), is connected to a retaining ring (18) which rests tightly on the outer pipe (16) and expands on both sides in the axial direction. The mounting disc (10) is supported at the sides by two elastic pressure rings (28) which are resistant to a temperature of at least 200 DEG C and are thermally and electrically insulating. For their part, these pressures rings (28) are held by two opposing discs (32) which are welded to the inner pipe (14) and close off the annular cavity between the pipes. <IMAGE>

Patent DE-3536829-A1 (DE)
Inventor: KRAMER WALTER
IPC: E04B2/74
Filed: 1985-10-16
Abstract: A partition which can be used in offices or like establishments has a row of neighboring upright rod-shaped sound-absorbing components with transversely extending openings for several flexible strip- or band-shaped metallic coupling elements in the form of leaf springs which enable the partition to be flexed so that the components are located in a common plane or together form a U-shaped, S-shaped, L-shaped or a like panel. The end portions of the flexible coupling elements are secured to the corresponding outer components, and the securing means can be provided with devices for coupling the partition to an adjacent partition. Certain rod-shaped components carry legs which are weighted and have roughened floor-contacting surfaces so as to reduce the likelihood of unintentional slippage of the feet relative to the floor, particularly when the rod-shaped components are not disposed in a common plane. The neighboring components can be assembled in partly compressed condition so as to tension the flexible coupling elements.

Title: Autonomous on-board locating system for determining the position and protecting against collision of robot and industrial trucks
Inventor: HOLZAPFEL WOLFGANG DR
IPC: G05D1/02
Filed: 1985-11-02
Abstract: When mobile robots or driverless industrial trucks have to approach arbitrarily predeterminable point targets with high accuracy in known operational areas which are partly built up (storage halls and others), a flexible locating system with low position measuring errors is called for which avoids collisions. Conventional guide aids such as induction loops and unreferenced compound navigation methods only incompletely meet these requirements. According to the invention, this object is achieved by an on-board locating system (Figure 2) in which distance sensors (13, 14) are used for continuously measuring the instantaneous distances of the vehicle from the lateral track limits for the purpose of referencing compound navigation. The distance sensors (15, 16) can be optionally used for measuring in or in opposition to the direction of travel. All measurement values are continuously compared with the digital map of the operational area, contained in an electronic reference memory (25), by means of a correlation circuit (26) and the position data associated in each case with the correlation peak are read out of the reference memory (25). A subsequent decision circuit (28) selects the correct position for the steering computer from the two available position measurement values (compound or reference data) on the basis of a plausibility check. <IMAGE>

Title: Process for the production of drawn high-quality tubes
Inventor: OPPERMANN WILLI-FRIEDRICH
IPC: B21C37/08
Filed: 1985-12-03
Abstract: The invention relates to a process for the production of drawn high-quality tubes from high-grade steel - titanium - non-ferrous metals - and their alloys, which are formed from a preliminary strip and welded. After the welding operation, the tubes pass continuously, in line, through the individual stands of a cold-reduction part and can there be reduced by 80% of their starting diameter. After the reduction of the continuous tube to somewhat more than the final diameter, normalising annealing is carried out continuously in the tube-annealing facility with subsequent rapid cooling. The continuous tube receives its final dimensions in a tube-drawing device likewise integrated into the line.

Title: Electronic gear train
Inventor: HOPF WOLFGANG
IPC: H03K23/68
Filed: 1986-03-15
Abstract: An electronic gear train exhibits a pulse counter (1) which is supplied with the pulses to be counted from a pulse generator (3). A control circuit (2) enables the pulse generator whenever a pulse of the input pulse sequence (fE) arrives and disables it again when the pulse counter (1) has reached a predetermined count. Accordingly, a number of output pulses determined by the predetermined count is generated for each pulse of the input pulse sequence (fE). When the predetermined count is reached, the pulse counter (1) is reset again in each case. The pulse sequence thus generated can also be supplied to a frequency divider (5), the output signal of which then forms the output pulse sequence (fA). For this output pulse sequence, fA = (k/N)fE holds true, where k is the predetermined count of the pulse counter (1) and N is the dividing factor of the frequency divider (5). <IMAGE>

Title: Apparatus for transporting and for facilitating the installation of support material
Inventor: PFEIFFER HEINZ-DIETER
IPC: E21D11/40
Filed: 1986-12-13
Abstract: The transport and the installation of the support material, in particular in carried-along roadways in underground working, is arranged more ergonomically in that a continuous transport rail is assigned to the frame which bears the working platforms. This transport rail leads up to the working platforms so that the support material, which is brought by the trolley, can be directly removed and used. This transport rail does not obstruct the workings of a road-driving machine since it can be swivelled round a swivelling link, which is arranged in the area of the frame, in such a manner that it approximately reaches the position of the longitudinal beams which bear the working platforms. An obstruction of the road-driving machine is thus ruled out; at the same time, however, it is ensured that the support material can be brought right up to the working place without intermediate storage or intermediate transport. <IMAGE>
Patent DE-3702707-A1 (DE)
Title: Method and apparatus for pouring metal covered with a slag covering
Inventor: RIES WILHELM DIPL ING
IPC: B22D41/18
Filed: 1987-01-30
Abstract: When pouring metal, especially steel, from ladles with a bottom outlet (1), some of the slag (13) is often sucked in owing to the formation of vortices and entrained into the casting. In so far as the slag (13) is not separated out, this leads to defects in the casting. The formation of vortices and hence the sucking in of slag (13) can be avoided if a ceramic, disc-shaped body (2) is mounted and held fast just above the bottom outlet (1) right at the beginning of the casting operation. This leads to the suppression of the vortices and the flowing melt is slag-free until the boundary surface between the metal and the slag (13) falls to the level of the bottom outlet (1). <IMAGE>
