Abstract: A beam form and slab form adjustment structure adapted for detachable mounting to a shoring frame of generally standard construction. Existing shoring frames with the present adjustment structure are useful in supporting and precisely aligning beam and slab forms relative to the vertical columns of a building. The adjustment structure includes a hinge arrangement enabling the associated shoring frame to retract so that the beam and slab forms can be moved for reuse at the next concrete pouring station.

Abstract: A beam form and shoring structure capable of precise alignment with adjacent vertical columns of a building structure to enable pouring of a beam between the columns. The beam form is supported along its length by a plurality of shoring frames which are retractable so that the beam form can be moved for reuse at the next pouring station. Each of the shoring frames includes side portions for supporting an adjacent slab form so that a floor slab can be poured at the time the beam is poured, the side portions being such that they can be lowered to strip the slab form from the freshly poured slab to enable the slab form to be moved for reuse at the next slab pouring station.

Abstract: Polymer forming reactions have been previously known comprising five and six member oxazoline ring oxazolidines and reaction products containing the basic structure with polyfunctional aromatic and aliphatic isocyanates and moisture. Five types of oxazolidines have been previously illustrated. Use of these polymeric products have been found to be limited as the class of oxazolidines described in the prior art result in objectionable dark colored products. This invention relates to an advance thereover in providing light colored end products by use of a novel and specific dioxazabicyclo octanes, a substituted specialized class of oxazolidine ring compounds.
