Abstract: A cranial remodeling orthosis comprises an outer shell and an inner shell, wherein the inner wall of the outer shell defines an inner cavity of the outer shell for insertion of the wearer's head. The inner shell that is removably connected to the outer shell. The inner shell defines a reduced inner cavity for insertion of the wearer's head that has a smaller volume than the inner cavity of the outer shell. The inner shell is removably connected to the outer shell in at least two different places distributed around the circumference of the inner shell.

Abstract: An assembly of a cranial remodeling orthosis comprises a first front piece of the shell and a first rear piece of the shell adapted for mutual removable connection. An inner wall of the first front piece of the shell and an inner wall of the first rear piece of the shell together define a target inner cavity of the cranial remodeling orthosis. A second rear piece of the shell is adapted for removable connection to the first front piece of the shell. An inner wall of the second rear piece of the shell and the inner wall of the first front piece together define a reduced inner cavity of the cranial remodeling orthosis that has a smaller volume than the target inner cavity of the cranial remodeling orthosis.

Abstract: Para-ethyl-oxyethylamino-aniline or one of its salts is employed as a reagent for testing the presence of chlorine in the water of swimming pools. The reagent dissolved or dispersed in a polypropylene-glycol ethoxylate is coated on to a support. When the coated support is stirred into the water a pink color develops in the water if chlorine is present and the intensity of the color can be used to gauge quantitatively the amount of chlorine present.
