Abstract: A load relief coupling device which interconnects a lower, supporting member and an upper, supported member of a concrete forming apparatus to permit quick and easy relief of the load on the members by a formed concrete structure. The load relief coupler includes a supporting coupler member, a supported coupler member, and an inner coupler member positioned between the supporting and supported coupler member. Coacting teeth on the inner coupler member and on the supporting and supported coupler members cause the coupler to move between a loaded, expanded position and an unloaded, collapsed position upon relative pivotal movement between the inner coupler member and the two supporting and supported coupler members.

Abstract: Broadly this invention provides inbred corn line ZS02234. The methods for producing a corn plant by crossing the inbred line ZS02234 are encompassed by the invention. Additionally, the invention relates to the various parts of inbred ZS02234 including culturable cells. This invention relates to hybrid corn seeds and plants produced by crossing the inbred line ZS02234 with at least one other corn line.
