Title: Fire-resistant cable shaft
Inventor: HEIDE HELMUT DR
IPC: H02G9/10
Filed: 1988-12-06
Abstract: Fire-resistant cable shaft with a double-walled sheet-metal casing, in the inner space (1) of which cables are laid, and between the inner (5) and the outer sheet-metal wall (4) of which an active heat-insulating material (2) is placed, which consists of a combination of substances which as a body exhibit endothermal reactions over a large temperature range of preferably about 60@C to 900@C while releasing water and/or gases. The gases and vapours arising during the action of heat are kept away from the space (1) by the inner wall and flow to the outside through small openings (6) provided in the outer wall (4) and thus counteract the penetrating heat front. A cover (3) closing the cable shaft is likewise filled with the combination of substances and, like the entire sheet-metal casing, preferably has a thin paint coat, cracking during the action of heat, as well as a reflecting top coat, these substances also being added to the paint coat. <IMAGE>

Patent DE-3940097-A1 (DE)
Inventor: OPPER BURKHARD
IPC: H04L1/00
Filed: 1989-12-04
Abstract: The invention concerns a process for bit-oriented data transmission using a high-level data-link control (HDLC) protocol. To increase the Hamming distance to the flag of the HDLC protocol, it is proposed that, at the transmission end, before the HDLC controller, two consecutive bits in the data field are each converted into a tuple codeword comprising more than two bits, one codeword having 0 bits and the three others only one 1-bit each. At the receiver end, after the HDLC controller, the codewords are converted back into two consecutive data-field bits. Using tuple and quadruple codewords, a Hamming distance of d = 3 and 4, respectively, can be obtained.

Title: Toxic gas scrubbing process - removes unwanted toxic ingredients by rotating active carbon filter, recycling part of scrubbed gas
Inventor: GABRIEL CHRISTIAN DIPL ING
IPC: B01D53/06
Filed: 1989-12-20
Abstract: In a variety of chemical processes gases are generated which bear unwanted toxic radioactive ingredients which are removed by means of a rotating active carbon filter. Part of the scrubbed gas flow is returned to the adsorbent, which it regenerates. This portion of the gas flow is then collected in a sealed container. USE/ADVANTAGE - There is no requirement for an additional supply of clean gas for use as a cleansing agent. Only a small portion of the gas becomes contaminated with radioactive materials. Operational requirements, the size and complexity of the equipment required, are reduced. The only gas which comes into contact with radioactive materials remains restricted to that portion of the gas which is piped to the scrubbing process.

A fibre layer is fitted to the machine side of the blanket structure, and on the paper side a fibre layer is in at least two layers, where the outer layer is of finer fibres, or a higher proportion of finer fibres, than in the lower layer. The laid warps are formed by a temporary weave, where the wefts are removed after the fibre layers have been needle bonded into place. ADVANTAGE - The blanket structure prevents paper marking and vibration, with an improved water extn. performance.
