A push pad releasable exit device with continuous deadlocking for mounting near a door edge for engaging a lock strike includes a housing having first and second sidewalls upon which are mounted two end walls and an internal wall parallel to the end walls, each of the end walls and the internal wall having a hole, the holes being aligned on a common axis, the first sidewall having a wedge stop projecting inwardly therefrom toward the axis of the holes in the end walls and the internal wall; a tapered latch bolt mounted on a cylindrical shaft, the shaft extending through the holes and having a provision for urging the latch bolt toward the lock strike; a wedge plate having a hole providing clearance around the shaft and aligned with the holes in the end walls, having a tab pivotally resting in a slot of the second wall, and having a corner distal from the tab resting against the wedge stop when the door is in an open position; a provision for sensing when the door is in a closed position and for flipping the wedge plate away from the wedge stop to grip the shaft and to thereby deadlock the latch bolt; and further provision for releasing the shaft in response to minimal deflection of the push pad to permit the latch bolt to ride over the lock strike driven only by the normal force required to open the door.

An integrated irrigation valve control device has a coil adapted to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment. Control circuitry is electrically coupled to the coil to control the flux at the coil. A housing covers at least a portion of the coil and at least a portion of the control circuitry.

An improved gear drive sprinkler has a pop-up spray head adapted for adjustable part-circle or full circle operation to deliver irrigation water over a selected terrain area. The sprinkler includes a pop-up riser; a gear drive transmission mounted within the riser includes a water-driven turbine for rotatably driving a speed reduction gear train, which in turn rotatably drives the spray head. A reverse assembly includes an upper trip unit defining an individually adjustable pair of end trip stops, and a lower shift mechanism including a shiftable director plate having first and second sets of angularly oriented jet nozzles for respective alignment with turbine jet ports for respectively driving the water-driven turbine and the gear train in a forward-drive or a reverse-drive direction. The upper trip is coupled to the director plate by an elongated trip rod which shifts the director plate between forward-drive and reverse drive positions. An adjustment cam can be manipulated to disable at least one of the end trip stops to permit spray head rotation through continuous full circle revolutions.

An irrigation control device comprises a coil adapted to develop an electromagnetic flux sufficient to cause actuation of irrigation equipment. Control circuitry is electrically coupled to the coil to receive control signals from an irrigation control unit and to control the flux at the coil. A spacer is configured to maintain the coil at a predetermined position relative to the control circuitry.

A mullion assembly mountable between a floor and a door frame includes an engagement assembly attached to either the floor or the door frame. A mullion defining a mullion cavity is positioned in removable attachment with the engagement assembly, and a cylinder lock assembly is positioned in the mullion cavity. The cylinder lock assembly has a key lock cylinder configured for positioning in either a locked position to engage the engagement assembly and hold the mullion in an upright position in the door frame, or in an unlocked position disengaged from the engagement assembly to permit removal of the mullion from the doorway.
