Patent DE-3639882-C1 (DE)
Title: Roofing providing shelter from sun and inclement weather
Inventor: WEISS HELGE
IPC: E04F10/06
Filed: 1986-11-21
Granted: 1988-05-26
Abstract: In the case of roofings providing shelter from sun and/or inclement weather and having a canvas which can be rolled onto, or unrolled from, a canvas-receiving shaft and whose edge, which is not held on the canvas-receiving shaft, is fastened on an opening-out profile pretensioned in the opening-out position, the forces acting on said opening-out profile are not usually sufficient to prevent the canvas from sagging. In order to keep rigid that part of the canvas which is unrolled from the canvas-receiving shaft, a brake disc (8) is rotatably mounted, by means of a coupling (10) which locks in the rolling-up direction of the canvas, on at least one spindle (1), whose relative position, with respect to a component (3) which is arranged thereon and belongs to the roofing, changes in dependence on the opening-out position of the canvas. Prestressed brake elements (7, 9) held on the component (3) act on the brake disc such that the relative position between spindle (1) and component (3) only changes, on rolling up the canvas, after overcoming a resistance, with the result that in order to tension the canvas, after reaching the desired opening-out position, the canvas-receiving shaft is to be rotated slightly in the rolling-up direction. <IMAGE>

Title: Component for use in conjunction with chain strands
IPC: B66C1/12
Filed: 1988-01-08
Granted: 1989-03-23
Abstract: In the case of a component for use in conjunction with chain strands, the links of which are produced from profile material, in particular round material, use is made of a basic body (1) which is preferably produced from a sheet-metal strip and has rectilinear basic-body portions (2 and 3) in which insertion openings (8 and 9) for chain links are arranged. Retaining slots (10, 11, 12) for chain links which have been introduced therein adjoin said insertion openings (8, 9). The diameter D of the insertion openings is smaller than the outer width of the chain links, with the result that a chain strand cannot simply be pulled through the insertion openings (8 and 9). On the other hand, it is, however, sufficiently large for it to be possible to insert the links of a chain strand individually into the insertion openings. <IMAGE>

Title: Measuring device for determining relative positions of two components of robot - has photometric detector on one component for sensing repeating sinusoidal curve on second component, to generate instantaneous position by computer reconstruction
Inventor: RICHTER HANS
IPC: B25J13/08
Filed: 1993-02-05
Granted: 1994-03-17
Abstract: One component (1) carries a repeating sinusoidal curve (5) and a second (2) carries two spaced curve sensors (10,11). A first relative motion (4) takes place between the two components in the curve's periodicity direction. A evaluation device computes the relative position. A second relative motion (12) of the two components, perpendicular to the first, depends on the first motion.  The evaluation device computationally reconstructs the instantaneous position of the curve from the sensor signals and derives information on the instantaneous relative position from it. ADVANTAGE  - Enables accurate measurement of relative positions of two components in one measurement process and independently of previous measurements.

Title: Device for turning a shaft of a subassembly to be assembled and/or checked
Inventor: SIMONIS GERHARD DIPL ING
IPC: B23P19/00
Filed: 1994-01-29
Granted: 1995-04-27
Abstract: After specified assembly steps have been carried out on subassemblies of this kind, rotary movements of the shaft (7) are required to prepare the next assembly step or for checking purposes. To this end, the intention is to specify a device which compensates for the unavoidable alignment, spacing and angle errors which occur during the 'docking' with the shaft of the respective subassembly. For this purpose, the device has a clamping head assigned to the shaft (7), a cardanically mounted housing (45) arranged coaxially with respect to the clamping head, a sensor and a drive. With the clamping head (1) released, the latter is fixed radially and axially relative to the cardanically mounted housing (45). When the clamping head (1) is in the clamping position, the fixing relative to the housing (45) is cancelled. A first bearing is provided in the region of the drive, while the second bearing is formed by the shaft (7) itself. One subsection of the drive line is designed as a torsionally rigid metal bellows coupling. <IMAGE>

Patent DE-4441653-C1 (DE)
Inventor: MUELLER HEINZ KONRAD PROF DR I
IPC: F16J15/16
Filed: 1994-11-23
Granted: 1995-11-02
Abstract: The sealing device consists of two lip seals of elastic material fitted one behind the other. The lips of both seals face away from the space (4) to be sealed and form a lubricant-filled buffer space (7). The sealing lip of the inner seal (1) acts as a pressure limiting or reducing valve. The outer seal is relieved of pressure in the prior art manner in that the fluid relieves the lip from inside and at the same time presses from outside via an elastomeric seal (63). The sealing device forms an additional (redundant) shaft seal becoming effective if the main seal should fail. It is used, for example, for sealing toxic or flammable fluids. A self-contained redundant shaft seal can be made by fitting two sealing devices one behind the other.
