IPC: E01C5/00
Filed: 1990-05-09
Abstract: In a road surfacing for areas able to bear traffic, principally in the region of filling stations, directly below the road surface (3), for example of composite paving stones (4), there is an impervious course (2) of a mixture of clay minerals, for example montmorillonite, and other mineral substances. This mixture is made up of fractions of different grain sizes in such a way that the volume of the finer grain size is in each case greater than the pore volume of the respectively coarser grain size and the greatest grain of the finer grain size is equal to or less than about 1/10 of the smallest grain of the coarser grain size. The mixture is laid in the dry, cohesionless state and, once the paving stones (4) have been put in place, is compacted by vibrating the latter by means of a surface vibrator. During this process, the finer grains respectively fill the pore spaces of the coarser grain size; excess fines rise upwards and fill from the bottom the joints (6) between the individual components (4). The moisture required for the effectiveness of the mixture as an impervious course is supplied after laying. <IMAGE>

Title: Reducing accumulation of fibre around drafting zone output roller covering - by treating the roller covering ensuring continuity in quality
Inventor: STAHLECKER FRITZ
IPC: D01H5/80
Filed: 1990-11-21
Abstract: Reducing the accumulation of fibre around the cots on a drafting zone, partic. at the output roller pair is achieved by treatment of the roller covering. Drafting units are arranged on a frame, each with a twisting device and creel for winding the reel. The drafting zone may consist of several pairs of rollers and aprons but it is the final pair (20,21) which is most significant for efficiency. The pressure for the top rollers is arranged by the spring in a cradle (18) which swivels open (22) when spinning is stopped at reel changeover, or for a broken end. A pneumatic device (27) has a valve control and connections (28) to automatically throw out the rod (30) attached to the cradle (18) at the time of stoppage. A service unit (19) then stops at the unit on the frame, and at this time a roller (24) which is held in a bath (25) of acetone is pressed against the synthetic roller covering on the pressure roller (21) to clear the accumulation of fibre, which may have wrapped around the roller. ADVANTAGE - The accumulation around the cot reduces the efficiency of the drafting zone. The regular treatment ensures continuity in quality.

Patent DE-4125812-A1 (DE)
Inventor: GUECKEL HARTMUT DIPL ING
IPC: H04L9/32
Filed: 1991-08-01
Abstract: The transmission method provides an at least doubled data transmission, the data message pairs (T1.1, T2) to be transmitted being represented, by means of suitable measures, by statistically mutually independent bit sequences; this is achieved by using a cryptological coding method in at least one of the data sequences generated at the source end. If this is given, the probability that the data messages in each case belonging together are falsified by interfering influences in such a manner that their falsification can no longer be detected by data comparison at the sink end can be considered as being negligibly small. The method according to the invention, in connection with failsafe signal sources (Q) and sinks (S) allows the failsafe data transmission via a non-failsafe data transmission system, the implementation of which can be completely unknown. <IMAGE>
