20100189663 | MOUTH RINSE COMPOSITIONS INCLUDING CHEMICALLY MODIFIED SILICA OR SILICATE MATERIALS FOR SUSTAINED DELIVERY TO TOOTH SURFACES - Novel mouth rinse (i.e., mouthwash) compositions that permit delivery of silica or silicate materials to the surface of teeth through common mouth rinsing procedures are provided. Such compositions must exhibit proper suspension of the silica or silicate materials (in particulate form) to prevent settling during storage while simultaneously providing proper mouth rinsing properties. Such silica or silicate materials may themselves exhibit any number of therapeutic or aesthetic benefits as long as such materials are easily transferred through mouth rinsing and exhibit proper affinity for deposit on target teeth upon contact therewith. Such silica or silicate materials should exhibit, in one embodiment, certain ionic charge levels as well as sufficiently small particle sizes to permit effective static attraction and eventual accumulation on target tooth surfaces. Methods of utilizing such mouthwashes for breath freshening and/or cleaning, as well as silica or silicate material tooth accumulation, are encompassed within this invention as well. | 07-29-2010 |

20130157497 | ELECTRICAL CONTACTING OF TENSILE CARRIERS IN SUPPORT COMPONENTS - A system for electrical contacting of tensile carriers in support means includes a support means and a contacting device. The support means has a casing and at least four tensile carriers. The tensile carriers are arranged parallel to one another in the casing and lie substantially in one plane. The contacting device has a contact element. The contact element has a cutting side for penetration of the casing, wherein the cutting side of the contact element is so guided through the casing that the contact element contacts the at least four tensile carriers at least by the cutting side. | 06-20-2013 |
20150158697 | DEFLECTION PULLEY COVER FOR MONITORING ELEVATOR CAR SUPPORT - A support apparatus is guided in an elevator installation via a drive and a deflecting roller. A cover is arranged at the deflecting roller. The support apparatus running in or running out at the deflecting roller is at least partly covered by the cover. The cover is monitored by a monitoring device so that deformation of the cover by the support apparatus is ascertainable. | 06-11-2015 |
20150210511 | ELEVATOR INSTALLATION DEFLECTING ROLLER - In an elevator installation a belt-like support is guided over a drive and over at least one deflecting roller. The deflecting roller includes an inner ring and an outer ring with a traction surface. The belt-like support loads the deflecting roller in a direction of loading, wherein the direction of loading is oriented substantially perpendicularly to an axis of the deflecting roller. The outer ring is mounted on the inner ring to be movable in axial direction so that in the case of a change in the direction of loading by an angle α the outer ring similarly inclines substantially through the angle α, whereby a perpendicular orientation of the direction of the loading with respect to the traction surface is substantially maintained. | 07-30-2015 |
