Title: Window washing system as an integrated or built-on part of the window wiper
Inventor: HERRMANN ERICH
IPC: B60S1/52
Filed: 1983-02-01
Abstract: Window washing system for cleaning wind screens on motor vehicles as a built-on or integrated part of the window wiper. The washing water is directed to the wiper blade through the arm of the window wiper which is of hollow design. By means of openings provided on the wiper blade, the washing water is sprayed onto the window in the direct vicinity of the rubber of the window wiper. By means of a particular design of the rubber of the window wiper, a mechanical control of the emerging washing water can take place. This control permits the washing water always to be sprayed only in front (in the direction of movement) of the window wiper. In contrast with conventional washing systems in which the visibility is always first worsened as a result of spraying on the washing water, the spraying on of the water controlled by the rubber of the window wiper provides a clear view more quickly without additionally impairing visibility.

Title: Process for producing a tubular weave and its use
Inventor: ROSSI GUIDO
IPC: D04C1/06
Filed: 1983-12-12
Abstract: What is proposed is a process by which, during the production of tubular weaves (10), an additional thread is inwoven in each case on at least two lace threads (8, 8') at a predetermined division in relation to the total number of threads and passes axially through the tubular weave (10) over its total length between the lace threads (8, 8'). This prevents the weave (10) from warping when it is being drawn off from the weaving mandrel (9), since the axial threads (7) absorb the tensile forces and therefore the diameter of the tubular weave (10) is not changed. <IMAGE>

Patent DE-3421855-A1 (DE)
Title: Defo-system
Inventor: POISEL OTTO KARL DIPL ING
IPC: B64G1/24
Filed: 1984-06-13
Abstract: The invention of the DEFO-SYSTEM is characterised in that it allows a federation of all those who believe in God to set up a worldwide defence system against the atheists. The artificially created DEFO-SYSTEM is based on a plurality of DEFOs which are composed of an early-warning system and a plurality of KILLER-NEFOs and which continuously orbit the earth, at a specific altitude, in a plurality of orbits. Using the early-warning system, these have the capability to record any attack by the enemy, irrespective of whether by rockets or flying objects, and to destroy them using the KILLER-NEFOs. The orbit around the earth is carried out at such an altitude that it cannot be reached by the enemy with rockets. There is thus no way that the DEFO-SYSTEM can be disturbed. In addition, it is no problem to replace the DEFOs, with their crews, on a two-weekly cycle. The hit probability of the KILLER-NEFOs is ensured in that they can destroy all hostile flying objects within a short time as a result of their own drive systems and high flying speed. <IMAGE>
