Abstract: Ballast systems for, particularly, inflatable decontamination shelters are described. The systems may be integrated into the overall structures of the shelters so as to avoid need for sand bags or other discrete weight-providing objects. They additionally may use liquids (rather than or in addition to solids) for weight-providing purposes, with the liquids including water supplied by the same plumbing system that supplies a shower of a shelter.

Abstract: A modular projector cage for operably supporting an optical projector and for forming a stacked frame using another identical modular projector cage is disclosed. The modular projector cage has a rectangular hexahedral open frame. A mounting plate is connected to a bottom section of the frame by first and second articulated elevation assemblies connected to respective sides of the mounting plate adjacent the mounting plate front end, and by a yaw assembly rotatably connected to the mounting plate adjacent the back end. The first and second articulated elevation assemblies are independently adjustable to adjust the elevation at each side of the plate so that the pitch and roll of the mounting plate can be adjusted. The yaw assembly adjusts the amount of yaw, which causes articulated movement of the first and second articulated elevation assemblies.

The parts are assembled in a manner that the bolt faces upwards and is effectively sealed in the assembly against any leak around the bolt by a first sheet of roofing material. The mount may be attached to a roof by fasteners around the periphery of the first base plate, and the second sheet of membrane material seals the fasteners and fastener holes.

Abstract: Devices, systems, and methods for constructing post-tensioned concrete slabs in a new floor construction that has a reduced gap distance between the slabs. The devices, systems, and methods can improve project construction time by reducing the time delay in accessing the floor underneath the slabs due to safety and/or weather conditions.

The retaining member includes a sidewall forming a positioning pole. The positioning pole includes a first positioning portion and a second positioning portion. When mounting the slide rail to the first bracket, the first positioning portion engages in a through hole of the first bracket, a first abutting portion abuts against the first bracket. When mounting the slide rail to the second bracket, the second positioning portion engages in a through hole of the second bracket, a second abutting portion and the first abutting portion engage with the second bracket.

Abstract: A material for use in building construction (partition, wall, ceiling, floor or door) that exhibits improved acoustical sound proofing and fracture characteristics optimized for efficient installation. The material comprises a laminated structure having as an integral part thereof one or more layers of viscoelastic material which also functions both as a glue and as an energy dissipating layer; and one or more constraining layers, such as gypsum or cement-based panel products modified for easy fracture. In one embodiment, standard paper-faced wallboard, typically gypsum, comprises the external surfaces of the laminated structure with the inner surface of said wallboard being bare with no paper or other material being placed thereon.

Abstract: A manufactured stone block for use in building a structure having a front surface with a simulated natural stone appearance. A portion of an upper surface of the block includes a recessed mortar joint for a user to place mortar therein to secure the manufactured stone block to an adjacent surface.

Abstract: An offset laminate seam system for storage bins for increasing the capacity of bolts in a seam of a storage bin. The offset laminate seam system for storage bins generally includes three or more panels connected together with two or more vertical rows of end fasteners to form a vertical seam. The interconnection of three or more panels continues to form a ring structure. A plurality of the ring structures are stacked upon one another and attached together with fasteners to form the wall of the storage bin and a roof is attached to the uppermost ring structure.

Abstract: A framing unit used with a plurality of replaceable panels that form a vertical retaining wall or a rigid enclosure to make raised planting beds. The framing unit includes two vertical end connectors, two horizontal top rails, at least one bottom rail, and a plurality of vertical panels. Each end connector includes two side flanges joined to form a vertical channel. Each end connector includes at least one hinge sleeve offset from the hinge sleeve on the opposite end connector adjacent framing units to be joined with a single anchor pin. The bottom and the two top rails are parallel and extend between the two end connectors. The top rails are separated by an upper gap that allow a plurality of vertical panels to be inserted into and supported by a channel formed on the bottom rail. The top edges of the panels are captured by the two top rails.

Abstract: Methods are provided for repairing an existing structure to cover at least a portion of the existing structure with a repair structure. Such methods comprise mounting one or more standoff retainers to the existing structure; coupling one or more standoffs to the standoff retainers such that the standoffs extend away from the existing structure; coupling one or more cladding panels to the standoffs such that the panels are spaced apart from the structure to provide a space therebetween; and introducing a curable material to the space between the panels and the existing structure, the panels acting as at least a portion of a formwork for containing the curable material until the curable material cures to provide a repair structure cladded, at least in part, by the panels. Corresponding apparatus for effecting such methods are also provided.

Abstract: Movable partition systems include an elongated, fixed drive member extending along a track, a partition that is automatically and manually movable along the track, and a motor carried by the movable partition configured to drive a rotatable drive member that is engagable with the elongated, fixed drive member. The rotatable drive member may be engaged with, and disengaged from, the fixed drive member. Methods of moving a partition along a track include actuating a motor carried by a movable partition to drive rotation of a drive member while the drive member is engaged with an elongated, fixed drive member, and manually moving the partition along the track while the rotatable drive member is disengaged from the fixed drive member. Methods of installing a movable partition system include configuring a rotatable drive member to be capable of engagement with, and disengagement from, an elongated, fixed drive member.

Abstract: An improved handrail for a staircase or ramp. In one embodiment, the handrail includes an elongated member such as a cylinder or bar that spans the length of the staircase or ramp and a riser barrier. The riser barrier has an extender portion and a riser portion. The extender portion of the riser barrier keeps the elongated member a sufficient distance horizontally from the riser portion that a person can slide his or her hand on the rail without interference. The riser portion projects vertically a sufficient distance above the elongated member to deter sliding down the elongated member. Thus, sliding on the member is deterred, while the function of the cylinder as a handrail is preserved.
