Abstract: The present techniques include a field armor system comprising hollow structures designed to be filled with field materials, such as soil, sand, rocks, or clay. At least one face of the structures is made from a projectile resistant plastic composite. The projectile resistant plastic composite panel may be made from a ceramic plastic composite, a fiber plastic composite, or interspersed layers of both. In one embodiment, the hollow structure comprises four connected panels that may be collapsed when empty. In another embodiment, the hollow structure may comprise hollow bricks designed to interlock to form a protective wall.

Abstract: The invention relates to an eyeglass frame having a portion of the frame removably coupled to the body of the frame to permit the removal and replacement of the lenses in the frame.

Abstract: A tray assembly for a germination floor assembly having a perforation tray sheet affixed to a rectangular frame assembly. The frame assembly includes a pair of parallel side members interconnected by a pair of end cross frame members. A plurality of longitudinal ribs extend parallel to the side members between the cross frame members. Reinforcing cross bars further extend between the side members and the longitudinal ribs. The cross frame members and reinforcing cross bars have a unique configuration to provide unimpeded flow of liquid wash through the tray assembly during cleaning. A tray assembly is attached to an adjacent tray by a bolt assembly. The tray assembly may be attached to supporting I-beams by hold down clamps. In one embodiment risers are employed for enhanced free flow of liquid wash during cleaning.
