Abstract: An improved riser for supporting a load in storage or transportation formed from a plurality of elongated, narrow, corrugated fiberboard strips positioned on edge and arranged side by side and adhered together along their contiguous surfaces to form a laminated core member. A sufficient number of strips are laminated together to form a core member having a suitable width to support and space a cargo load above a supporting surface or other vertically stacked loads. The strips forming the laminated core member can have any desired length which is necessary to support the intended loads. The core member can be reinforced by applying one or more lateral bands to reinforce and prevent delamination of the strips. The core member for the riser can be inserted within an elongated box-like cover formed from corrugated fiberboard material to encapsulate and sheath the outside surfaces of the core member.

Abstract: A surveyor's retro-reflective device, such as a corner cube prism, is striped along the reflective surfaces to provide an internal visual center target. The precise center of the prism is identified by the visual target which allows the prism to be used both for distance measuring purposes as well as visual alignment for the one step setting of surveying points or locations. The corner cube prism has the ridges of the intersecting reflective surfaces on the back of the prism striped or lined either with a stripe having equal thickness or tapered towards the center apex of the prism. The stripes are formed with a highly visible paint, ink, tape, or sheet material. This arrangement produces a highly visible visual center target. The prism target can be mounted in an enclosed case and the case can be rigidly mounted or tiltably mounted on a horizontal axis to tilt the prism in a vertical direction for use in mountainous terrain.
