Abstract: A movable barrier wall system includes a housing assembly 12 that has an interior chamber 32. A barrier member 14 is made of a buoyant material having a selected density. The barrier member 14 floats vertically within the chamber 32 when a liquid is present. The barrier member 14 may be made from a closed cell foam core 34 that is clad with a fiberglass mesh material then the assembly is infused with a resin material. Alternatively, the core 34 may be made from a plurality of elongated rods 38 that are individually clad and reinforced with a shear layer. The individual barrier member modules 15 may be assembled in an end to end relationship with an elongated vertical seal member therebetween. The barrier member 14 may be selectively raised prior to and in anticipation of a flood situation of a nearby body of water by a pump and control system that may be automatically or manually controlled. At least one passive backup system is provided for filling the chamber when the pump or control system fails.

Abstract: An automatically-actuated sealing device is disclosed which seals a gap between a door bottom (or edge) and a surface defining part of an opening through which weather, dust, insects, etc. may otherwise pass. The sealing device includes a support element attachable to the door bottom, a seal actuating element movably supported by the support element, a sealing element moved by the seal actuating element into a sealing position, and a plurality of metal, plastic or metal and plastic spring elements which couple the seal actuating element to the support element and urge the seal actuating element to seal the gap. The sealing devices operate by coupling the device to the opening defining surface so that opening and closing of the door generates movement of the seal actuating element. A projection on the seal actuating element is engaged by the door jamb or a bearing element attached to the jamb, and is laterally moved in response to opening and closing the door.

Abstract: A sealing device automatically seals a gap between a door bottom and a floor in response to closing movement of the door. The sealing device includes a support element attachable to the door bottom, a seal actuating element movably supported from the support element by spring elements, and a sealing element carried by the seal actuating element. The sealing device may be mounted to the inside or outside of a door, or mortise-mounted in the door, and may be mounted to left- or right-opening hinged doors, or to sliding or articulated closures, and may be provided as an after market or OEM device. The spring elements in the preferred embodiment are one-piece and are integrally connected to both the support element and the seal actuating element, thereby forming a one-piece sealing device preferably made of plastic.

Abstract: A lock which is rekeyable or programmable to operate with a different key from the exterior thereof without disassembling it or removing it from a lock assembly in which it is assembled is disclosed. The lock may be rekeyed through the keyway so that the lock appears from the exterior thereof to be a conventional lock, or from the end opposite the keyway from the interior of a door, or from a side of the lock which requires disassembly of the lock from its lock assembly. The lock includes structure defining a movable shear line that can be adjusted from the exterior of the lock without disassembling the lock itself. Such structure may comprise a rotatable cam and a pin tumbler and an axially adjustable set screw. Security of the lock is improved by selectively restricting or blocking access to the rekeying of the lock in the interior thereof with a gate or shutter, or various combinations of gates or shutters.

Abstract: A lock which is rekeyable or programmable to operate with a different key from the exterior thereof without disassembling it or removing it from a lock assembly in which it is assembled is disclosed. The lock is rekeyed by a change key through the keyway so that the lock appears from the exterior thereof to be a conventional lock. The change key which can not operate the lock adjusts a movable shear line formed by what is in effect an externally adjustable tumbler. The lock includes a plurality of pin tumbler sets and a plurality of cylinders disposed one in the other in the lock casing. The pin tumbler sets and the cylinders cooperate to from a plurality of common pin tumbler shear lines, i.e., shear lines formed by a number of individual shear lines of individual pin tumbler sets. In a given position of the adjustable shear line, only one of the keys will position the pin tumblers to form the proper common pin tumbler shear which is aligned with the adjustable shear line to operate the lock.
