Patent DE-3512502-A1 (DE)
Title: Method and apparatus for the production of a double-walled pipe for carrying solids
Inventor: ESSER ALEXANDER
IPC: C21D9/14
Filed: 1985-04-06
Abstract: It is known to insert one tube into another, the outside diameter of the core tube being, with certainty, markedly smaller than the inside diameter of the outer tube. After the fitting together of the two tubes, the core tube is brought into firmly adhering surface contact with the inner surface of the outer tube by repeated successive hardening with radial expansion in stages. In order to be able to fix a core tube in an outer tube even where the outside diameter of the core tube 1 corresponds approximately to the inside diameter of the outer tube 2, it is proposed to push the core tube 1 into the outer tube 2 while simultaneously expanding the latter or to reduce the core tube 1 while simultaneously expanding the outer tube 2 and then to press the core tube 1 against the outer tube 2 in a single hardening operation. <IMAGE>

Title: Digital communication system with an nB/(n+1)B line code
Inventor: ALI AMAR DR
IPC: H04L25/49
Filed: 1985-07-20
Abstract: In a digital communication system with an nB/(n+1)B line code in which the code converter at the transmitting end, depending on the accumulated disparity and the word disparity of the current input word, inverts or does not invert this input word, the receiving device must be informed whether or not an inversion has taken place in the transmitting device. According to the invention, a control bit (M) is not transmitted directly to the receiving device for this purpose, but is logically combined with one bit of a bit string (BO) which closely approximates a pseudo-random bit string and which is also present at the receiving end or can be generated there. In a further development of the invention, which can also be used in any other nB/(n+1)B code converters, the additional transmission capacity provided by the (n+1)th bit is used at regular intervals for the transmission of a sync word generated in the transmitting device (Fig. 1) and the receiving device is synchronised with this sync word. <IMAGE>

Title: Equipment for producing low-alkali cement clinker
Inventor: MUELLER MARTIN DIPL ING
IPC: F27D13/00
Filed: 1985-10-07
Abstract: The invention relates to equipment for producing low-alkali cement clinker and concerns the field of cement production by the dry process and semidry process. The aim of the invention is a simple and inexpensive plant, by means of which low-alkali cement clinker can be produced at high productivity and without pollution, which plant converts the waste products arising into a utilisable form and allows utilisation of secondary heat. This aim is fulfilled by achieving the object of developing a plant, in which harmful constituents, in particular alkali compounds, are removed from the flue gases of cement clinker-burning plants. According to the invention, this takes place by arranging a water jet reactor operated with scrubbing fluid on a flue gas discharged point between the preheater and the rotary kiln of cement clinker-burning plants. After the gas discharge, intensive heat exchange and mass transfer between the scrubbing fluid and the flue gas discharged by means of vacuum then takes place. To the water jet reactor, a receiver vessel is connected in which the mixture of scrubbing fluid and remaining moist flue gas is separated, the solid constituents precipitating. Downstream of the receiver vessel, a sludge precipitator is provided.
