Title: Shaft seal for the drive shaft of a gear pump
Inventor: HERTELL SIEGFRIED DIPL ING
IPC: F16J15/00
Filed: 1985-12-04
Abstract: A gear pump (1) for delivering and metering cellulose acetate solutions is described which has a novel shaft seal for the drive shaft (10), which prevents leakage and setting of the spinning fluid on the drive shaft. The stuffing box packing has an annular chamber (21) filled with nitrogen between two groups of packing rings (17, 18) which are pretensioned by spring elements (19). The spinning fluid escaping along the drive shaft (10) of the gear pump (1) is drained at the lowest point of the annular chamber (21) into a leakage collection vessel (27) which likewise is filled with a protective gas. The ingress of air oxygen is prevented, so that the cellulose acetate solution does not set, which would lead to erosion phenomena or render the packing rings ineffective. <IMAGE>

Patent DE-3607141-A1 (DE)
Inventor: BRENNECKE HERMANN DIPL ING
IPC: A62C3/04
Filed: 1986-03-05
Abstract: The method involves monitoring values occurring at successive times of the system pressure in the potentially explosive areas and comparison of these values with a predetermined pressure threshold, the exceeding of this pressure threshold being taken as the initiating criterion for introducing explosion protection measures. According to the invention, a constant value is not specified as the pressure threshold, instead the pressure threshold is updated continuously, depending on the respectively prevailing system pressure. As a result, the pressure threshold can be set with a smaller safety margin than before above the system pressure.

Inventor: PFEIFFER GUENTHER
IPC: G11B23/04
Filed: 1986-05-24
Abstract: The object of the device is to extend the conventional processing of data, in particular for personal computers, and their storage, while taking into account the advantageous direct access, by a further conventional type of processing data in serial access in such a way that the different data media (magnetic tape and magnetic disc) are combined to form a processable cassette in such a way that a magnetic tape to be transported back and forth by two reels is enclosed in a rotationally movable manner by two magnetic discs lying horizontally and congruently one above the other. Taking into consideration the rotational speed of the two interconnected magnetic discs, the rotational speed of the magnetic-tape reels, which runs counter to the direction of rotation of the magnetic discs, is controlled by magnets to be excited with like or unlike polarity and form part of the cassette. Once produced in this form, the data media remain inseparably connected before, during and after processing. As the serial, multitrack data medium, the magnetic tape has the special task of storing or audibly reproducing information produced by voice or music, doing so either with interaction or without interaction with the direct-access data medium of the magnetic disc. This information could be, for example, commentaries on data or files, foreign language texts, explanations, teaching courses or news items, which the corresponding design of the ...
