  • Patent number: 5997149
    Abstract: A reversible, backlit grooming mirror has a planar mirror and a concave mirror mounted back-to-back in a reflector unit in parallel relation, with a space between the mirrors. The reflector unit is mounted for rotation in a mirror frame between a first position presenting the planar mirror to a user and a second position presenting the concave mirror to the user. A light source such as a halogen lamp is disposed in the space between the mirrors. A switch responsive to rotation of the reflector unit terminates electrical power to the lamp unless the reflector unit occupies a position in which one of the mirrors is in an operative position before the user.

  • Patent number: 5896864
    Abstract: A steamer for a steamable hair curler includes thermally isolated cold and hot water reservoirs. Water in the hot water reservoir is heated by a PTC heater. The volumetric t capacity of the hot water reservoir is very small. The PTC heater has an intrinsic cutoff temperature high enough to boil water in the hot water reservoir and low enough to prevent deterioration of any component parts of the steamer, even in the absence of water in the hot water reservoir. Due to the thermal isolation of the reservoirs, water in the cold water reservoir is not substantially heated during normal operation of the steamer.
