Abstract: A barrier system for partitioning a space includes wall panels which interlock with each other to provide a modular wall that is fire rated. The interlocking panels are assembled in the barrier in columns using a first tongue and groove assembly and a panel lock using a strike and latch supported by the tongue member and groove member, respectively. The barrier system further includes cap panel which adjoin each at a joint to provide a modular ceiling that is fire rated. The cap panels are assembled in the barrier to corresponding wall panels using a second tongue and groove assembly and a panel lock using a strike and latch supported by the tongue member and groove member, respectively.

Abstract: A barrier system for partitioning a space includes panels which interlock with each other to provide a barrier that is fire rated. The interlocking panels are assembled in the barrier in columns using a tongue and groove assembly and a panel lock using a strike and latch supported by the tongue member and groove member, respectively. Each panel includes a peripheral frame (that is shaped to provide the tongue and groove members), opposed steel side faces mounted to the peripheral frame, and an insulation block filling an interior space delimited by the peripheral frame and the opposed steel side faces. The insulation block includes a pair of insulating material layers that sandwich a radiant barrier layer. A floor module supports a bottom edge of the panel and an interface module supports a side/top edge of the panel. The floor/interface modules are configured with telescoping sections and are length trimmable.

Abstract: A barrier system for partitioning a space is formed by panels which interlock with each other to provide a barrier that is fire rated. The interlocking panels are assembled in the barrier in columns which include at least two panels. A first horizontal joint between two panels of the barrier in a first column is vertically offset from a horizontal joint between two panels of the barrier in a second column that is adjacent to the first column at a vertical joint. Each panel is made of a laminated structure including a supporting frame around a core layer, barrier layers on opposed surfaces of the core and skin layers on the barrier layers. Tongue and groove construction interlocks the panels and a locking structure formed by a tapered hook in the groove engaging into a slot of the tongue locks horizontally adjacent panels to each other.

Abstract: A wall for partitioning space within a building comprises interconnected barriers. For adjustable height, each barrier comprises a lower panel and a slidable and overlapping upper panel. Barriers are interconnected at vertical edges by a combination of rigid pins and slots or by hinge assemblies. Mating male and female parts of a hinge assembly attach to both panels of adjacent barriers with adjustable heights, and enable selective angling of barriers relative to each other. A filler barrier, for filling a space along a wall that is less or more wide than a standard width barrier, has sliding inter-nested frame parts that attach to the two panels of a standard barrier. A clip secures the top of a barrier to the grid of a suspended ceiling.

Abstract: A magnetic disc memory unit is presented wherein a pair of read/write heads are attached to and driven by a continuous belt driven by a stepper motor. The read/write heads move linearly, and they retract to a landing position fully off the disc when the unit is shut down. The heads carriage structure is counterbalanced by a counterbalance assembly to allow operation at all altitudes and minimize vibration and shock problems.
