Abstract: A water jet head with a plurality of water jets arrayed over a head teeth side opposite a smooth head cheek side that comfortably slides along a user's cheek when in use. An array of bristly clusters as in a brush may be interspersed among the plurality of water jets. A quick release head connector connects to a wand with wand quick release connector cooperating with the head connector. The wand on a distal end of a flexible hose connects to a water source, preferably a showerhead, at its proximal end.

Abstract: A method for making a honeycomb carrier body and product formed thereby in which a corrugated foil strip is provided having opposite side edges and corrugations oriented at an oblique angle to the side edges. The corrugated foil strip is folded on lines perpendicular to the side edges to provide a core body having fluid passages between opposite ends and a shaped periphery defined by parallel outside folds in the corrugated strip. The core body thus formed is inserted into a jacket tube so that folds at the core body periphery are in compressive contact with the jacket tube, and the periphery of the core body is joined to the jacket tube. Preferably, the corrugated foil strip is coated before the folding step, such as with an oxide layer, a catalytic coating or both, prior to the folding step.

Abstract: A method and apparatus for continuously forming corrugated sheet material in which corrugations are oriented at an oblique angle to side edges of the sheet material. The apparatus includes a pair of corrugating gear rollers supported for rotation on respective first and second parallel axes, the corrugating gear rollers having meshing linear teeth parallel to the first and second axes and providing a corrugating nip. At least one of the first and second gear rollers are movable toward and away from the other of said gear rollers to position the teeth in respective conditions of corrugating and released meshing engagement at the corrugating nip. The sheet material is directed to the corrugating nip along a path at an oblique angle to the axes of the corrugating gear rollers and the corrugating gear rollers are driven to corrugate the sheet material while the teeth are alternated between conditions of corrugating and released meshing engagement at the corrugating nip.
