Abstract: A combination drying unit has a towel roll rotatably held within a housing. By activation of a switch, a motor drives a drive roller that has an idler roller biased thereagainst for advancing the paper towel stream through a first opening of the housing. A blower is also disposed within the housing and blows a stream of air through at least one second opening on the housing. A sensor activates the motor and the blower. A sensor detects the presence of a towel stream and deactivates the motor until this sensor no longer detects the paper towel stream. Another sensor detects the absence of a towel stream, deactivates the motor, and increases the length of operation of the blower upon activation of the switch. This sensor also illuminates a service light indicating either a jam condition or an out of paper condition.

Abstract: A combination drying unit has a towel roll rotatably held within a housing. An air blower, powered by a motor, is also held within the housing. The motor provides a stream of air from the air blower through an opening in the housing. The motor also powers, via an appropriate transmission unit, a guide roller, which engages a towel stream and dispenses the stream through a second opening. A sensor detects a towel outage within the device and communicates, in appropriate fashion, the towel outage condition.

Abstract: A dual roll dispenser is disclosed. The device comprises a housing unit having a first paper towel roll and a second paper towel roll mounted therein. Paper automatically dispenses paper from one of the rolls while the second roll remains idle. When a sensor detect that the roll being dispensed is exhausted, the device automatically engages the second paper towel roll and begins dispensing from this second roll. Displays, both local and remote, are activated to communicate a paper absent condition. The device can be used in standalone configuration or in conjunction with an air blower wherein activation of the device activates the air blower for a preset amount of time and thereafter dispenses a single paper towel sheet.

Abstract: A combination drying unit is disclosed. The device consists of a air blower unit that forces air out through a venting system in order to dry a person's hands and face. After completion of the air blowing process, a paper towel roll, mounted within the drying unit, dispenses a single paper towel out though the bottom of the unit.

Abstract: A fluid delivery system (10) is provided for delivering at least one chemical (26) onto a field in a desired concentration. A carrier fluid (67) is provided for diluting the farm chemical (26). The mixture is pumped through a spray boom (18) onto the field by a main fluid pump (74). The chemical (26) is delivered to the inlet port (76) of the main fluid pump (74) by a chemical pump (54). The chemical pump (54) is operated by a variable speed stepping motor (56). The speed of the stepping motor (56) is controlled by a speed sensing wheel (88) to provide a uniform concentration of chemical on the field independent of vehicle speed. The motor speed is also controlled by a thumbwheel switch (116) to deliver a desired concentration on the field compensating for drive vehicle wheel slippage. The motor speed is also adjusted to calibrate the delivery concentration to the nozzle pattern through calibration switches.
