Abstract: An electric strike includes a housing and a two-position mode selector for selecting a mode of the electric strike. Specifically, the two-position mode selector is operable from outside the housing, and the two-position mode selector is configured to allow the electric strike to selectively operate in a first mode, such as a fail-secure mode, or a second mode, such as a fail-safe mode.

Abstract: An electric strike includes a housing, a keeper pivotally arranged in the housing, and a holder slidably arranged in the housing. The electric strike also includes a blocking element slidably arranged in the holder, and the blocking element is configured to selectively prevent a rotation of the keeper and allow the rotation of the keeper. Moreover, the electric strike includes a two-position mode selector operable from outside the housing, and the selector is configured to selectively move the holder from a first position to a second position and vice versa. The electric strike also includes an actuator configured to selectively move the blocking element.

Abstract: The electrically-operated door strike provides rapid and easy selection between fail-safe and fail-secure modes. A keeper is pivotably arranged in a housing. To prevent the keeper from pivoting, the keeper has at least one abutment, which a blocking surface or surfaces of a blocking element either contacts (door locked) or does not contact (door unlocked) when the keeper tries to pivot. The blocking element is movable by a solenoid, between a first (unenergized) position and a second (energized) position. The blocking element and solenoid are mounted in a holder, which in turn is slidably mounted in a housing, for movement between one of two holder positions, namely a fail-secure position and a fail-safe position. In the fail-secure position, the blocking surfaces are opposite the keeper's abutments in the unenergized position, and in the fail-safe position the blocking surfaces are opposite the keeper's abutments only when the actuator is energized.

Abstract: A sheet moving apparatus comprising: a track having first and second spaced side walls and a third wall therebetween to form a sheet receiving space therebetween; and a sheet feeder for moving a sheet towards the third wall and thereafter moving the sheet in a downstream direction along the track. The sheet feeder comprises a rotatable member having a surface positioned in the sheet receiving space and a rotary drive enabling the rotatable member and its surface to be rotated. The sheet feeder also includes a rotatable or pivotal member moveable between first and second positions with regard to the rotatable member, with the pivotal member having a roller member to cooperate with the surface of the rotatable member to move a sheet towards the third wall when the pivotal member is in the first position, and the rotatable member and its surface are rotated.

The sheet feeder comprises a rotatable member having a surface positioned in the sheet receiving space and a rotary drive enabling the rotatable member and its surface to be rotated. The sheet feeder also includes a toggle member moveable between first and second positions with regard to the rotatable member, with the toggle member having a first member to cooperate with the surface of the rotatable member to move a sheet towards the third wall when the toggle member is in the first position, and the rotatable member and its surface are rotated.
