Abstract: 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.

Abstract: A locking cap assembly is selectively locked into place within a tubular opening, such as the open end of a fire department connection. The locking cap assembly has an expandable element and a spreader element that is operatively connected to a locking bolt. As the locking bolt is rotated by a key, the spreader element is translated longitudinally through a tapered longitudinal bore in the expandable element, and the translation of the spreader element respectively expands and contracts the extendable element as the spreader element moves in the bore between first and second positions. The locking bolt includes a pair of cooperating lock washers having opposed cam surfaces, and a pair of opposed Bellville compression washers that apply axial pressure to the lock washers, allowing the locking bolt to be self locking during use for increased reliability and security.

Abstract: 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.

Abstract: 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 we

Abstract: A fire-rated removable mullion, includes a top fitting mounted to a door frame lintel, a bottom fitting assembly, a mullion head capable of detachably engaging the top fitting, a mullion tube having provisions for mounting between the mullion head and the bottom fitting assembly, and another provision for accommodating thermal expansion of the mullion assembly to resist warping of the assembly. Where desired, a mortise cylinder lock can be included to limit removal by unauthorized persons.

Abstract: 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.
