Title: Plastic corrugated tube with integrally molded sleeve coupler
Inventor: HEGLER WILHELM
IPC: F16L11/11
Filed: 1987-01-14
Granted: 1991-01-02
Abstract: ABSTRACT OF THE DISCLOSURE         A plastic corrugated tube, in the outer wall of which has a circular ring corrugation, is provided on one end with an integrally molded-on plain coupler having an approximately cylindrical inner face.  Its inside diameter is substantially equal to the outside diameter     of the corrugated tube, and the circular rings that form the corrugation and are spaced apart from one another by the distance     in the longitudinal direction of the tube each have the approximate cross section of a trapezoid tapering toward the outside; to this end, they have an approximately annular-cylindrical outer wall section     and slightly inclined side wall sections adjoining the outer wall section.          To enable simple laying of the tubes by inserting the tube end into a sleeve coupler even when there are relatively large tolerances in diameter and in particular in the outer diameter of the tubes, yet simultaneously to attain a tight coupler union, at least a portion of the outer wall sections of the circular rings is provided with an annular elevation that can be elastically deformed radially inwardly in common with the respective outer wall section.  The outside diameter of the elevation, in the undeformed state, is slightly greater than the inside diameter     of the sleeve coupler.

Granted: 1993-07-27
Abstract: ABSTRACT     A sensor for an inclination measuring device is disclosed which comprises a capsule  part-filled with a conductive liquid.  First to fourth electrodes A-D are disposed within the capsule in contact with the liquid.          An electrical signal is applied between electrodes C, D and one then the other of electrodes A, B, to derive a signal indicative of the degree of immersion of the electrode A, and then the electrode B within the liquid.  The ratio of these signals is related to the angle of inclination of the capsule about the reference axis O and relative to a first reference angle defined at the gap between the electrodes A, B.   The capsule 1 is also constructed to compensate for thermal effects. by forming the sides of the capsule so that they are responsive to pressure change within the capsule caused by thermal expansion of the contents of the capsule to expand the volume of the capsule, to keep the level of liquid therein constant.

Abstract: A pressure-sensitive adhesive tape can be produced by photopolymerization and yet its pressure-sensitive adhesive layer can have a dark appearance when it contains a pigment or dye plus finely divided hydrophobic silica.  As compared to a tape which is identical except for omission of the hydrophobic silica, the adhesive layer of the tape is substantially darker and usually of substantially more intense color.  Furthermore, the tape exhibits better adhesive properties than do otherwise identical tapes containing no silica.  The pressure-sensitive adhesive preferably is an acrylic pressure-sensitive adhesive and may be filled with glass microbubbles which afford a foamlike appearance and character.
