Abstract: Variable length polypropylene ties are used to form an insulated concrete wall by holding sheet materials in a fixed distance part so concrete can be cast between the two sheet materials.

Abstract: An automatic toothbrushing assembly has a handle casing and a reservoir casing connected to each other by mating grooves and ribs. The reservoir casing has a reservoir space containing toothpaste, and which has an inner stepped series of lateral feet and an opening at an upper end thereof, and a cover. The handle casing has an outer stepped series of feet and contains a brush having a handle and a brush head, with a spring extending between the handle casing and the brush handle. A latching assembly permits latching of the cover to the handle casing. A piston is located in the reservoir space and has elastic lateral wings which incrementally advance upwardly along the stepped series of feet of the reservoir casing, and an elastic piston tail which incrementally advances upwardly along the stepped series of feet of the handle casing upon application of downward sliding force ion the reservoir casing relative to the handle casing, thereby extruding toothpaste to a position where the brush head is located.
