摘要:
A system for consecutively dispensing paper sheet material from a stub roll and a primary roll which utilizes a pivoted transfer door to locate a lead end portion of the primary roll in dispensing position responsive to disengagement between the transfer door and a pivoted lever supporting the stub roll.
摘要:
Apparatus and method for reducing current drain and current spike impact on a dispenser electric motor by employing a series of supercapacitors in a power supply current to provide at least a portion of the energy requirement of the dispenser electric motor upon initial energization.
摘要:
A system for harvesting and storing energy including photovoltaic structure continuously harvesting energy from an internal lighting system, at least one supercapacitor for receiving and storing electrical energy produced by the photovoltaic structure, and a microprocessor continually powered by the supercapacitor and programmed to activate an electrically operated device when the stored energy in the supercapacitor exceeds a minimum voltage charge level sufficient to maintain operation of the microprocessor.
摘要:
Apparatus for dispensing paper toweling from a roll of paper toweling includes a rotary damper resisting formation of overspin slack in the paper toweling resulting from a pulling force applied to the paper toweling. Control mechanism changes the rotary damper from an operative condition to an inoperative condition responsive to reduction of the diameter of the roll of paper toweling.
摘要:
A paper toweling dispenser includes an electric motor driven toweling support roller, a handle for rotating the toweling support roller and a one-way clutch including a stabilized pawl, which allows the handle to rotate the toweling support roller only in a single direction of rotation transporting toweling on the toweling support roller to an exit opening of the dispenser when the electric motor does not drive the toweling support roller.
