Abstract: A method is disclosed to embed a perforated body in a cake of soap and to align that body perforation with a transverse hole in the soap so that a support post can easily penetrate the body hole to support the soap by the embedded body.The flat sheet like body is inserted edgewise into bar soap through a slot in the soap created during the soap extrusion. The problem of aligning the hole in the body with the hole in the soap during the high speed production of cake soap is overcome by first placing the body in the soap at the desired location within a distance of one half the diameter of the hole in the body. The final exact location of the body hole is achieved by a pointed punch creating a hole in the soap by the point on the punch picking up the body hole and shifting the body as needed by a corresponding sized portion of the punch entering the body hole.
Abstract: An animal guard for use in a field pipe has a generally circular baffle member formed of relatively thin sheet material mounted for pivotable movement in the direction of effluent flow at a perimetral point inwardly of the pipe at an axial predetermined distance from the open end of the pipe.
