Abstract: A dowel assembly to be anchored in a borehole in a receiving material includes a container positioned around the axis of the borehole and located between an abutment at one end of the dowel assembly and the receiving material into which the assembly is inserted. The container is formed of two parts with one part being telescopically displaceable into the other. An hydraulic mass capable of expanding when mixed with a reaction liquid is filled into the container. The expandable hydraulic mass maintains the force acting on the dowel assembly when there is relaxation of the force originally generated between the dowel assembly and the receiving material. The container has openings through which the reaction liquid can pass into contact with the hydraulic mass. The hydraulic mass can be activated by immersing the container in water.

Abstract: The lock housing has a slot in a top wall via which a coded card key can be inserted to bring into alignment coded magnetic areas on the card with magnetically responsive elements of the lock to unlock the locking mechanism and enable rotation of either a knob or lever arm to open the door. The card moves a spring actuator against a coupling spline to engage it with a spindle spline carried by a shaft interconnected with the knob or lever arm handle. The sliding coupling spline is integral with parts which interrelate with the door lock mechanism such that rotation of the knob or lever arm will now effect release of the door locking mechanism. When the card is fully inserted, the mechanism is maintained in the unlocked condition and the card may be released to turn the knob or handle with the same hand. Spring-loaded members separate the coupling and spindle splines as the magnetic card key is withdrawn from the housing slot.

In this state, a panel is fitted in the space between the two opposed portions, and a bolt can be inserted through the channel-shaped part and panel and screwed into the nut.

Abstract: A cover mechanism for covering a lock, having a key opening, on a lock support surface includes a cover plate which may be pivoted between a closed position in which the key opening of the lock is covered, and an opened position in which the key opening is exposed. A detent arrangement engages the cover plate at a first point to hold it in its opened position until a key is inserted into the key opening and rotated towards an unlatching position, whereupon the detent arrangement engages the cover plate at a second point and prevents movement of the cover plate into its closed position. The cover plate is released when the key is withdrawn from the lock such that the cover plate is free to move into its closed position.
