The rotation member comprises two rotation blockers, each blocker providing one interface surface adapted to be in contact with a complementary interface surface of one of the capture members, each blocker further provides a surface opposite to the interface surface comprising an inner cylindrical surface. The rotation member comprises a central disc element forming a rolling surface as complementary surface to the inner cylindrical surface of the corresponding rotation blocker. The rotation member comprises two nuts, wherein each nut is associated to one locking screw of a corresponding capture member. Each locking screw of a capture member extends through the corresponding rotation blocker and engages the corresponding nut for an individual locking of each capture member. | 03-17-2011 |
| 20110087226 | EASY TO CLEAN CLAMPING DEVICE - An easy to clean clamping device has at least one clamping assembly having two jaws. The jaws form at least one recess to accommodate an element to be clamped along the longitudinal axis of the recess. A locking unit is provided to allow closing of the jaws against the force of a spring element. The locking unit has a shaft extending along an axis and through bores of the jaws. The shaft has a head for operating the clamping action abutting against the uppermost jaw. A locking element is provided having a through bore and which locking element can be arranged between the head and the uppermost jaw. One portion of the locking unit has a larger diameter than the bore of the second jaw and the head of the locking unit has a smaller diameter than the bore of the adjacent jaw. The locking element comprises at least one locking surface which can be brought into positive locking with a corresponding surface of the head for blocking removal of the locking element. | 04-14-2011 |
| 20120089144 | LOCKING SCREW WITH SYNCHRONIZED THREAD - A targeting system for a bone plate having a bore therethrough with a first thread adjacent an outer surface of the bone plate and a second thread adjacent a bone contacting surface. The first thread has a larger diameter than the second thread. A targeting device has a coupling portion, an outer sleeve with an axial through bore for guiding a boring tool and a bone screw into the bone plate bore.

| 20080204044 | Method for detecting islanding operation of a distributed generator - An exemplary method comprises the steps of introducing a reactive current reference square wave, detecting load voltage changes at every change in the reactive current reverence wave, and determining whether the detected load voltage changes exceed a predefined islanding detection threshold value, indicating a loss of mains and an islanding operation of the power generator. With the exemplary loss-of-mains detection, islanding can be detected within a shortest period of time, even if the local islands active and reactive load matches exactly the distributed generators active and reactive power generation. So even without a sudden voltage change, unintentional islanding can immediately be detected and control electronics can safely turn of the distributed power generator. | 08-28-2008 |
