Abstract: The present invention is an adjustable hanger bar assembly for a light fixture. The assembly maintains structural integrity between first and second bars to support a recessed light fixture while being extended to distances where typical mounting assemblies fail. The hanger bar assembly comprises first and second bars which slidably engage one another. One of the first and second bars comprises a foldable foot which may be extended to increase the length of the hanger bar assembly.

Abstract: A lock cylinder suitable for mortise locks comprises mechanically operating tumbler pins controlled by a key and at least one electromagnetic tumbler. The cylinder is arranged in a cylinder casing and comprises a coil as well as a locking member which can be displaced by electromagnetic forces for an additional tumbler pin which is spring-loaded in the locking direction and with a reading device which detects a key code. The locking member is pivotally mounted in a recess in the additional tumbler pin and enters the locking position in front of a stop on the cylinder casing.
