Abstract: An improved roller skate includes a shoe portion, front and rear wheels, and a bracket coupling the wheels to the shoe portion. The have a "generally" spherical shape which allows the skater to maintain a rolling surface of each wheel on the floor or ground, while leaning the skate by a relatively large degree with respect to a line extending perpendicular to the floor or ground. Each wheel has a rigid inner core and a softer outer cover. The inner core includes an axle housing connected to a hollow, "generally" spherical, rigid shell by a plurality of radially extending spokes. The bracket coupling the wheels to the shoe portion includes arms coupled to the wheel axles. The shape of the bracket and bracket arms are designed for strength as well as to allow for a high degree of skate inclination (lean or angle) with respect to the ground or floor without contacting and scraping the ground or floor.

Abstract: A device for applying a liquid to the hair of an individual, the device comprising a comb member and a container, wherein: the comb member has an elongate tubular main body with opposed axial ends and a longitudinal axis extending between the ends, the main body encloses a longitudinal passage which extends along the longitudinal axis, is open at one of the axial ends and is closed at the other one of the axial ends, and the longitudinal passage includes means at the one axial end for receiving the container, and a plurality of elongate teeth carried by the tubular main body and extending parallel to one another from the main body in a direction transverse to the longitudinal axis, each of the teeth having a base connected to the main body, a tip remote from the base, and a linear passage extending in a straight line from the base to the tip, the linear passage being open at the base to communicate with the longitudinal passage in the main body and being open at the tip, each of the teeth having a frustoconic
