Abstract: A time-based electrical appliance multi-mode control circuit and indicator arrangement which is connected to a power supply and an on and off switch. Upon turning the switch on, power is simultaneously supplied to the electrical appliance load and to a dual timer circuit. A first timer in the circuit is immediately energized causing a first indicator to represent an on state to the user. After a predetermined length of time, the first timer causes one output to go low, turning off the on state indicator and respectively turning on a ready state indicator. A second timer is then activated for a second predetermined period. At the end of the second period, the ready state indicator is turned off and the standby state indicator is turned on. At the same time, a triac connected to the electrical appliance load is turned off causing the power to the load to be automatically switched off.

Abstract: A heat generating curling implement includes a generally cylindrical body member about which hair may be wound and containing two heat radiating U-shaped plates with interlinking base portions with a positive temperature coefficient heating element sandwiched between the inside surfaces of the interlinked base portions. Each plate has two heat radiating legs. All legs extend substantially in the same direction. The legs of both plates partially co-extend. The interlinking base portions do not contact one another. An electrode pin is in electrical contact through a contact plate to one of the radiating U-shaped plates. The electrode pin does not extend through the PTC element and does not extend through the base portion of the radiating plate. An electrode ring surrounds the electrode pin and is electrically insulated therefrom and electrically connected to the other radiating U-shaped plates through a second contact plate.

Abstract: A hair dryer including a blower for selectively generating a current of air at various flow rates, a thermostatically controlled electrical heater for selectively heating the current of air at various heat generation rates and a switch mode switch and associated circuitry for selectively activating the heater and the blower and including a three position switch actuated by a single button and having a first normal mode position wherein the heater is activated to generate heat at a first heating rate and the blower is activated to generate a current of air having a first flow rate, a second cool-shot mode position wherein the heater is activated to generate heat at a second heating rate which is less than the first heat rate and the blower means is activated to generate a current of air having a second flow rate which is less than the first flow rate and a third hot-shot mode position whereupon the heater is activated to generate heat at a third heating rate which is equal to or greater than the first heat rat
