Title: Circuit arrangement for combining bit flows (bit streams) of a plurality of time-division-multiplex input lines, which are operated in bit-serial form, onto a supermultiplex line which is operated in bit-parallel form, and for distribution of the bit flow of such a supermultiplex line onto a plurality of time-division-multiplex output lines which are operated in bit-serial form
Inventor: RAU PETER DIPL PHYS DR
IPC: H04J3/04
Filed: 1981-09-17
Abstract: Circuit arrangements of this type are required, for example, in the case of PCM time-division-multiplex exchanges, in the case of which switching array (switching matrix, switching network, switching stage) assemblies are provided in the switching array, which switching array assemblies produce (by means of pure time position conversion) both time and spatial allocation from time channels which are formed on time-division-multiplex input lines to time channels which are formed on time-division-multiplex output lines. As a result of the use of line-specific serial/parallel converters and parallel/serial converters, known arrangements of this type are costly (complex) and require a large amount of space. According to the invention, more favourable conditions in this respect are achieved in that a multiplexer (M) is provided in one transmission direction on the side of the single multiplex lines (LE0, LE31), and the serial/parallel conversion takes place on the side of the supermultiplex line (SMLi), and, in the other transmission direction, the parallel/serial conversion takes place on the side of the supermultiplex line (SMo), and a demultiplexer (DM) is provided on the side of the single time-division-multiplex lines (LA0 to LA31). <IMAGE>

Patent DE-3244064-A1 (DE)
Inventor: KOLLROSS GUENTER
IPC: A22C11/02
Filed: 1982-11-27
Abstract: For cyclically charging the filling tube of a sausage stuffing and closing machine with ready-for-stuffing tubular casing lengths, a tubular casing material flatly wound upon a supply roll is first withdrawn, opened and, in respectively one section length, drawn upon a support. Thereupon the drawn-on casing section is divided off the material cord and, along with the support, is placed ahead of the charging tube for conveyance thereto while at the same time, a new casing section is drawn onto another support to repeat these working steps in permanent alternation of the two supports. The invention resides in that each support after being placed ahead of the charging tube along with the casing section drawn thereonto is pushed in the same direction in which the drawing onto the support was performed beforehand, onto the charging tube up to the stopping means, whereupon the support is advanced in the same direction, pulled out of the retained casing section and, finally, removed laterally. This will save precious time until a new charging operation starts and enhance the degree of efficiency. A corresponding apparatus for implementing the method is equally suggested.

Patent DE-3319040-A1 (DE)
Title: Rotating mechanical seal
Inventor: BERGEN VON ERNST-PETER DIPL IN
IPC: F16J15/00
Filed: 1983-05-26
Abstract: The sealing arrangement with a pair of sliding rings (13, 19) is intended to provide sealing at high pressures, in the presence of corrosive media and in the case of large shaft diameters and, to increase reliability, additionally contains a stuffing box packing (33) and an inflatable auxiliary seal (9). If, in the event of the pressure of the medium to be sealed off persisting, the auxiliary seal (9) is inflated against the collar (48) fixed on the shaft (100), large axial forces occur and reliable fixing of the collar, composed of a corrosion-resistant material, on the likewise corrosion-resistant shaft coating (101) is thus not guaranteed. The collar (48) is therefore designed as part of a shaft sleeve (44) which is fixed on the shaft (100) at its other end (44a), which is not exposed to the medium, by fixing means (45, 46) of high-strength material. The collar (48) is designed in such a way that it accommodates one sliding ring (13) in a manner free from stresses and deformations. The fixing means (45, 46) secure the shaft sleeve (44) even against high torques, which may occur at the seals. <IMAGE>

Title: Process for the regeneration of waste foundry sands
Inventor: GODDERIDGE VOLKER DIPL ING
IPC: B22C5/18
Filed: 1984-01-11
Abstract: The invention relates to a process for the regeneration of waste foundry sands. Such waste sands consist of mixtures of old sand with sludge materials of organic and inorganic binder components, such as active and dead-burnt bentonite, bituminous coal dust, resins, polystyrenes, fine quartz dust, etc. It is known to process such waste sand having a small sludge material content by thermal treatment and subsequent mechanical after-purification. This processed waste sand can however be reused only to a limited extent. Waste sands with sludge material contents of 10-12% and more cannot be regenerated by the known process. With the three-stage regeneration process according to the invention, the processing of waste sands is possible independently of their sludge material content, the regenerated material being usable unrestrictedly even for core production. This three-stage process consists of a mechanical pre-purification, a thermal treatment of the pre-purified waste sand, and a mechanical after-purification.
