Title: Method and device for the continuously adjustable control of the speed and/or acceleration of hydraulically driven working tools
IPC: F15B21/12
Filed: 1983-04-21
Abstract: The invention relates to a method and a device for the continuously adjustable control of the speed and/or acceleration of hydraulically driven working tools for linear or rotating or oscillating movements during pulsating loading with a hydraulic alternating flow. The object of the invention is to vary the speed and/or acceleration of working tools driven hydraulically by means of control units of this type, and in fact especially to periodically vary the speed and/or acceleration, so that not only can resonance points of the object to be machined be used by varying the frequency but so that especially advantageous values of the acceleration can also be utilised. This object is achieved by the invention owing to the fact that one or more pulsating fluid flows from or to the working tool are restricted and/or intensified to a varying degree upstream or downstream of the generator of the hydraulic alternating flow. The device according to the invention is distinguished by at least one adjustable restrictor valve in a feed line to the generator of the hydraulic alternating flow or to the working tool, or in the return line.

Title: Method and device for monitoring or controlling the welding operation during the welding of workpieces by the arc welding process
Inventor: GAWLIK NORBERT
IPC: G03F9/00
Filed: 1983-12-10
Abstract: In the method according to the invention, the arc in the electric arc welding is scanned during the welding operation by an emission spectrometer acting as a sensor so that, if the workpieces to be welded are different, for example, in a material constituent, signals can be obtained by means of the emission spectrometer, which signals indicate an unsatisfactory position of the weld seam relative to the materials to be welded and indicate that satisfactory through-welding is achieved. The signals can be analysed for monitoring and/or for controlling or readjusting for the purposes of obtaining satisfactory welding of the workpieces at the weld seam.

Title: Fire-retarding wall elements with connecting devices
Inventor: GAMM KLAUS
IPC: E04B1/94
Filed: 1983-12-17
Abstract: Fire-retarding wall elements have at their abutting end edges a groove into which a connecting profile, which is preferably designed as a rectangular tube, can be inserted. The hollow cross-section of the connecting profile is filled with a heat-resistant insulating material in order to reduce the heat transmission at the joint between two wall elements. For installation purposes, the connecting profile can be pushed completely into a hollow space of at least one wall element. Further measures serve for reducing the heat transmission at this hollow space.

Patent DE-3411168-A1 (DE)
Title: The associative array
Inventor: HILBERG WOLFGANG DR ING
IPC: G06F17/30
Filed: 1984-03-27
Abstract: It is shown how associative memory modules can be arranged and connected to one another in an array in such a way that very high-performance associative systems are produced. Essentially, two basic structures are concerned. In one, the external key words are fed directly to all the associative memory modules and in the other the external key words reach only the memory modules which are at the edge of the array. In the array itself there is in both cases a strong influence on each memory module by its neighbours. If the items of information are stored permanently in the manner of an associative read-only memory, these systems can even replace ROMs of much greater capacity. Their use appears to be advantageous in the case of all structured data sets, such as for example languages, in which varied relationships exist between the structure elements (words of a sentence). Finally, a plurality of associative arrays can also be connected to form hierarchical and non-hierarchical systems, making possible the efficient storage of very many, very long text sequences.
Patent DE-3420371-A1 (DE)
Inventor: SENG BERTHOLD DIPL ING
IPC: H02K7/118
Filed: 1984-06-01
Abstract: Arrangement for starting a synchronous motor of which the rotor (15) energized by a permanent magnet is provided to insure the starting of the motor under load with a circumferential play on the drive shaft (27). Thus, a substantially load-free starting of the rotor (15) is obtained, whereby, after passage of the circumferential play, a first coupling part (24) attacks a second coupling part (25) connected to the drive shaft (27) and drives the latter. To obtain a predetermined rotational direction of the rotor there is provided a rotational direction blocking unit (33, 38) which, in a given rotation direction of the rotor releases the rotation of the drive shaft (27), while the opposite rotation direction of the drive shaft is blocked.

Title: Process for producing silicon for solar cells
Inventor: AULICH HUBERT DR
IPC: C01B33/025
Filed: 1984-10-29
Abstract: In the carbothermal reduction of quartz, for example petroleum coke or soot pellets, quartz glass in the form of broken pieces or pipe fragments such as those which accumulate cheaply as waste in the manufacture of quartz glass equipment is used instead of quartz. Not only do the quartz glass fragments consist of very pure quartz glass, thereby ensuring the necessary purity, but they also ensure good loosening of the reaction mixture during reduction. The process is used to produce silicon for solar cells.

Title: Compact luminaire for a luminaire post
Inventor: SCHMIDT GERD DIPL ING
IPC: F21Y103/00
Filed: 1985-06-14
Abstract: The invention relates to a compact luminaire for a luminaire post, having a box-shaped luminaire housing for accommodating at least one fluorescent lamp and a reflector surrounding the latter at least partially, which housing is formed from an opaque upper wall, opaque sidewalls and a transparent bottom shell and on which there are located ballasts and an opening for insertion of the pole pin. This luminaire is intended with regard to its configuration and the arrangement of the electrical components not only to be still better adapted to the recently introduced compact fluorescent lamps, but also to be rendered easier to maintain and less temperature-dependent with regard to the luminous efficiency. This is achieved by arranging the ballasts, in a manner accessible from outside on both sides of the pole head via separate housing covers, in a flat pole head housing which forms immediately adjoining the luminaire housing a rear extension thereof, and whose bottom wall and upper wall lie in approximately the same planes as the bottom shell or upper wall of the luminaire housing.
