Abstract: A shirt construction with a wing type collar is disclosed, having first and second strips of material secured to the neck band beneath the collar on opposite sides of the frontal opening. A third strip of material is pivotally attached to the first strip and has a surface of a hook or a pile type material, the first and second strips being of the other type. The size and arrangement of the strips is such that the third strip may be superposed with and releasably adhered to the opposing surface of the first strip, concealed beneath the collar when the latter is worn in the open condition, or turned 180.degree. about its pivotal mounting to extend across the frontal opening and adhered to the opposing surface of the second strip to close the frontal opening in the collar area at a desired width between a predetermined maximum and minimum.

Abstract: A connector plate for the panels of a concrete form corner constitutes an elongated rectangular plate having a first portion with holes for bolting to an edge portion of a panel so that a second, locking portion extends beyond the edge of the panel. The locking portion has a notch the outermost land of which is parallel to the edge of the panel. The notch is greater in width than the plate thickness, and the arrangement is such that the notch can interengage with the notch of an identical connector, inverted relative thereto, to hold together the edges of two mutually perpendicular panels to form a corner construction. The connector plate includes apertures for whaler bars which can be placed in position to abut the outermost surfaces of the panels and to prevent distortion during concrete pouring.
