A rotary wing aircraft apparatus includes a body and a rotor pair connected to the body by an arm. The rotor pair has an upper rotor driven by an upper motor and rotating about an upper rotor axis and a lower rotor driven by a lower motor and rotating about a lower rotor axis. The upper and lower rotor axes are tilted with respect to each other. Tilting the axes away from the arm increases the distance from the rotor blades to the arm, and decreases the risk of the blades of the rotor contacting the arm. In an aircraft with a plurality of arms extending from the body, and a rotor assembly connected to each arm, the arms can be pivoted from a flying position, where the arms extend laterally outward to a folded position where the arms are positioned substantially parallel and adjacent to each other.

A shaver (10) includes a razor blade (20a, 20b) that cuts hairs coming into contact therewith. A heating element (26a, 26b) is bonded to the razor blade (20a, 20b). The heating element (26a, 26b) generates heat when an electric current is passed therethrough, the generated heat being directly supplied to the razor blade (20a, 20b). A battery (32) generates electric current, and electrical conductors (28, 30, 50, 52) route electric current generated by the battery (32) to the heating element (26a, 26b). A handle (16) is adapted to be held by a user for manipulation of the shaver (10). Suitably, the handle (16) houses the battery (32), and a head (12) houses the razor blade (20a, 20b) and heating element (26a, 26b) bonded thereto, the head (12) being selectively attachable to and detachable from the handle (16).

A gel-dispensing disposable razor comprising a transparent plastic tubular handle with forked supports at one end, and a multi-bladed cartridge pivotally attached to the forked supports of the handle. A packet of shaving gel is resident in a reservoir formed in the handle, and a positive displacement pumping mechanism allows finger-operated extrusion of the gel out of the module, through the handle into a pivoting manifold which spreads the gel outward around the cartridge. The gel is extruded from the handle through the manifold which evenly extrudes the gel into laminar flow paths that emanate outward from around the pivoting cartridge. All of the tubular handle, carriage, manifold and positive displacement pumping mechanism are molded plastic components for cost-effective mass production. Moreover, the transparent handle provides an indication of the amount of gel left therein, and is further equipped with a series of spaced rubberized annular ribs to provide a sure hand-grip. The razor provides an exceptionally smooth shave for approximately 3-5 usages, after which the device can be conveniently disposed of.
