An embeddable air duct block includes a tubular member extending between a pair of rectangular plate members spaced from each other. The tubular member has a pair of open ends and an interior passageway. One plate member has an inner surface coupled to one open end and a plurality of holes in fluid communication with the interior passageway. The other plate member is coupled to the tubular member and has a duct opening aligned with the interior passageway. Two cement cavities are preferably formed on opposite sides of the tubular member. An air duct is formed in a concrete block wall by installing and securing the air duct block in the concrete block wall. The blocks are coupled together by cementing slurry poured into the cavities. Optionally, reinforcing bars can also be utilized within the cement cavities and at least one cavity of the concrete block wall.

An apparatus for shaving that contains a rectangular dispenser detachably connected between a razor handle and a disposable blade carrying head. The dispenser includes a reservoir that may be divided into open compartments that are in direct communication with separate conduits in the blade head that extend adjacent to the blades carried by the disposable head. Once installed, placing the apparatus's beneath a running faucet fills the reservoir and the internal baffling structure retains the water in the apparatus until contact with the user's face. The user applies a water soluble lubricant to the face and allows the lubricant to dry into a film. Shaving foam may also be applied to the face over the dry lubricant. When the blades are placed against the user's face, the water flows from the reservoir onto the blades and the user's face adjacent thereto to reactivate the lubricant just prior to the passage of the blades thereover.

A toothbrush holder for training the bristles of a toothbrush into a preferred shape utilizes a pair of opposed cam surfaces to urge a pair of rigid compression members against the sides of the mass of bristles along a line at a predetermined height on the bristles. The resultant bristle structure is maintained by repeated storage of the brush in the holder between use.
