Abstract:
A structural arrangement is described m pneumatic floor spring of reduced dimensions, which requires a hole in the floor for its installation, providing a shielded structure that prevents the water accumulation, such pneumatic floor spring keeps the door (100) closed by the force exerted by the plunger (80) and when the door is opened, the pin (30) spins along with the cam (60) which, with the double helicoid, pushes the descendant track (70) and the plunger (80).
Abstract:
A powered door for nuclear power plant consists of an embedded steel plate, a door frame welded on the embedded steel plate, a pair of hinge devices, a group of door panels, a group of opening and closing devices and a group of bolt devices; the door panels are fixedly arranged within the door frame through the hinge devices; the opening and closing devices are arranged at the upper ends of the door panels, and the bolt devices are arranged in the internal sides of the door panels. The powered door is fire-proof, explosion-proof and bulletproof, and is safe and long in service life, thus, the powered door can be used for nuclear power engineering which is constructed based on new standards.
Abstract:
Provided is a water barrier panel device which includes a control member controlling a water barrier panel. The water barrier panel device includes a water barrier panel which blocks passage of water, a water collection pit which is configured to permit inflow of water, a water collection bucket which is moved in a vertical direction based on an amount of accumulated water, an interlocking mechanism which interlocks the water barrier panel and the water collection bucket, and a control member which controls movement of the water barrier panel.
Abstract:
A hinge assembly is provided for a frame structure. The hinge assembly includes a first generally flat plate having an inner face, an outer face and a bolt-receiving bore therethrough. The bolt-receiving bore extending between the inner face and the outer face along a bore axis at an acute angle to the outer face. A second generally flat plate has an inner face, an outer face and a bolt-receiving bore therethrough. The bolt-receiving bore in the second plate extending between the inner face and the outer face thereof along a bore axis at an acute angle to the outer face. A pin pivotably connects the first plate to the second plate. A first lip extends from the inner face of the first plate and a second lip extends from the inner face of the second plate.
Abstract:
A door hoist includes a bracket, drive sprocket, ring gear, hub assembly, set of planetary gears, and governor shaft. The drive sprocket has a drive sprocket axis. The ring gear is fastened to the drive sprocket. The ring gear has a ring gear axis that is in alignment with the drive sprocket axis. The hub assembly includes a connector to receive a door drive shaft and secure the door drive shaft in a fixed rotational alignment with the hub assembly. The set of planetary gears is rotationally mounted to the hub assembly. The set of planetary gears is configured to mate with the ring gear. The governor shaft includes a sun gear, brake assembly, and link. The sun gear is configured to mate with the set of planetary gears. The brake assembly has an engaged position and a disengaged position. The sun gear is rotationally fixed relative to the bracket in response to the brake assembly being in the engaged position. In response to the brake assembly being in the disengaged position, rotation of the sun gear is unfixed relative to the bracket. The link secures the brake assembly in the engaged position. The link is configured to melt in response to an ambient temperature exceeding a predetermined temperature.

Abstract:
A garage door bracing arrangement comprises a plurality of vertically extending door-stiffening column members, which are pivotally attached to upper mounting brackets affixed to garage building structure directly above the garage door opening. Lower mounting brackets are affixed to second ends of the column members and are anchored to the garage floor directly beneath the upper mounting brackets. The door-stiffening column members are configured as generally hollow, rigid, telescoping sections having longitudinal channels which retain fasteners that project from sides of the telescoping sections, so as to pass through holes in mounting brackets that affix the door-stiffening column members to the garage building structure, and deflection brackets that secure the door-stiffening column members to door panel hinge joints. The upper mounting bracket is configured to allow for a pivot swing type of movement, that eliminates pull stress from the upper bracket, when the bracing system is placed in an outward or suction condition created by high cross winds.
Abstract:
A hanger and driving assembly for hanging clothes or curtains that has a simple and reliable driving mechanism involving an easy operation to close and open the curtain without the need of cords, the assembly having a rail fixed to a wall or a roof of a building, a rod extending inside and along the entire length of the rail, the rod having at least one helical thread length, at least one driven runner being slidably mounted on the rod, the runner comprising a threaded bore through which the rod passes whereby the threaded bore is engaged with the helical thread length of the rod so as to be moved along the rod when the rod is rotated, the runner having at least one pair of wheels rotatably mounted to rotate about an axis and along inner surfaces of the rail the runner having a horizontally projecting hanging arm passing through an elongated opening extending along the bottom or the front wall of the rail.
Abstract:
A kit, for use with a building having a sectional overhead door and at least one vertically disposed strut for reinforcing the door against wind damage, unauthorized entry and the like, enabling quick installation in and easy removal of the strut from a door reinforcing position. Structure is are provided for releasably securing the top of the strut to the building and the bottom of the strut of the floor. Further, structure is provided to releasably secure the hinges of the sectional door to the reinforcing strut by using members having a finger portion for insertion into the hollow pin joining the hinge leaves at the knuckles. Structure is also provided for releasably securing the top and bottom of the strut to the top and bottom of the door. Similarly, apparatus for reinforcing an overhead door with a strut and releasable securing structure is also disclosed.
