  • Patent number: 4914833
    Abstract: An automatic hand dryer contains a heating element and a motor which drives a squirrel cage fan. The fan exhausts air past the heating element to a downwardly-directed outlet. A base or mounting plate is adapted for flush mounting to a wall. The axis of the fan is perpendicular to the base plate and wall to which the dryer is attached. A control or sensing circuit emits signals to a detection zone beneath the outlet and monitors the zone for reflected signals indicative of a user's presence. The circuit operates to energize and deenergize the power circuit to the fan motor and heating element. Upon detection for a predetermined period, the circuit energizes the power circuit. The control circuit deenergizes the power circuit upon interruption of the reflected signals for a predetermined period, or after a predetermined maximum time period of continuous detection. Under the latter condition, the stimulus reflecting the emitted signals must be removed from the detection zone to reactivate the control circuitry.

  • Patent number: 4803787
    Abstract: The procedure to prevent the formation of condensation on tools that are heated in use and are cooled by a circulated coolant is particularly relevant to plastic moulding machines. To avoid the build-up of condensation from dampness on the cooled tools a dry air veil, as herein laid down, is produced by direct blowing-on of the tools, through which the cooling water temperature of the circulated coolant in the tools can be further reduced making shorter work cycles possible. By use of a special control equipment, the dew point on the tool surface is picked up which regulates the cooling water temperature accordingly.

  • Patent number: 4754769
    Abstract: A nail dryer includes a clamshell shaped base for resting the user's hand thereon. A C-shaped heating member is attached to the perimeter of the base by rib braces. The member includes two separated C-shaped channels housing a rope heater. The ribs form segmented air slots between the base and the channels. A clamshell shaped cover fits over the base and the C-shaped heating member. The closed cover forms an air chamber. The channels also have air induction vents below the heater for allowing outside air to pass by the heater and then to enter the air chamber. Air also enters via the air slots and is heated as it flows by the two channels. The hot air entering the air chamber is deflected by baffles. The wet fingernails are positioned in the chamber, and the hot air flow rapidly bakes the polish. The hot air vents at the cutaway rear of the cover. The stepped fashion of the rope heater and the two channels influence the air flow and currents in the chamber.
