Abstract: A door locking device, in particular an electromagnetic door locking device, for a door with a rotary catch for a closing bolt of the door, wherein in particular said rotary catch can be acted upon or is acted upon in particular by a torque, wherein the rotary catch has a closing bearing surface. The door locking device includes a pivoting body, in particular a pivoting locking body, and a lever body, wherein the pivoting body is connected to the lever body by a connecting body, wherein the connecting body is connected by a first joint to the pivoting body and by a second joint to the lever body, wherein in a closed position of the rotary catch the closing bearing surface of the rotary catch is in contact or is able to be brought into contact with the first joint between the pivoting body and the connecting body.

Abstract: An electromagnetic holding magnet and a method for manufacturing the same, and an electromagnetic locking element that, that in a preferred embodiment, is a lock in a container of an oxygen emergency supply system of an aircraft. The electromagnetic holding magnet includes a yoke and a retaining plate interacting with the yoke as an anchor. At least one permanent magnet generates a magnetic retaining flux in the yoke that includes a first yoke leg and a second yoke leg as well as a middle pole. The middle pole is surrounded in sections by a magnetic coil. The first and second yoke legs are arranged symmetrically in relation to the middle pole and the magnetic coil.

Abstract: A device for locking a holding pin connected with a cover with a holding pin for the cover, with a magnet. The device has a rotational body held in an end position by the magnet. The rotational body has inside a receiving area provided with an inner wall for at least one ball and for the holding pin, wherein in the receiving area of the rotational body the at least one ball is arranged between the inner wall of the receiving area of the rotational body and the holding pin arranged inside the receiving area under formation of a form fit for locking the holding pin and for unlocking the holding pin by turning the rotational body, the clamp effect of the at least one ball is reduced or removed through the spacing of the at least one ball from the holding pin so that the holding pin is movable.

Abstract: An actuation magnet is provided for moving a closure needle of a hot-runner nozzle of an injection molding tool. The actuation magnet has an armature which is coupled in movement to the closure needle and may be displaced between first and second cores by subjecting at least one coil to current. A permanent magnet is arranged in a manner such that it exerts an additional magnetic force on the armature in at least one, preferably two, movement directions.
