| 20120125601 | SEPARATING DEVICE FOR TUBULAR FLOW-THROUGH DEVICES - The invention relates to a separating device for tubular flow-through devices ( | 05-24-2012 |
| 20120118203 | SUSPENSION FOR PRODUCING A LAYER INCREASING THE COEFFICIENT OF FRICTION, MOLDED PART HAVING SUCH A LAYER INCREASING THE COEFFICIENT OF FRICTION, METHOD FOR THE PRODUCTION THEREOF, AND USE THEREOF - The invention relates to a suspension for producing a friction-increasing layer on a substrate, which comprises a liquid suspension medium, a predominantly inorganic binder or precursor compounds thereof and suspended hard material particles. The invention further relates to a shaped body comprising a substrate and a friction-increasing layer which has been applied to at least part of the surface of the substrate and comprises a predominantly inorganic binder matrix and hard material particles embedded therein, where the thickness of the binder matrix is less than the average particle size of the hard material particles so that the hard material particles project from the binder matrix and where the friction-increasing layer has been formed from a suspension according to the invention. The invention likewise relates to a process for producing the abovementioned shaped bodies and also their use for producing press or clamp connections and also as securing element. | 05-17-2012 |
