TL;DR: In this article, a method and apparatus utilizing successive reverse osmosis stages to produce highly purified water from potable water in a manner particularly suitable for use in a coin operated vending machine is described.
Abstract: Method and apparatus utilizing successive reverse osmosis stages to produce highly purified water from potable water in a manner particularly suitable for use in a coin operated vending machine. The flow rates in the reverse osmosis stages are matched so that no storage tank is required between them. Operation of the purification stages is controlled by the level of purified water in a reservoir from which it is dispensed, and the level is automatically maintained within a predetermined range. A sump pan is mounted under the remainder of the machine to catch spillage, accidental overflow from the reservoir and the reject (brine) flow from the reverse osmosis stages, a sump pump is automatically actuated when the water reaches a predetermined level in the sump pan, and a valve at the feed water inlet is closed automatically in the event that the water level gets too high in either the reservoir or the sump pan. The machine will not accept coins in the event that the water in the reservoir drops to a predetermined level or fails to meet a desired standard of purity, and means is included for adding minerals to the purified water dispensed, if desired.

TL;DR: In this paper, a processor is configured to increase the motor speed in response to an inadequate pumping rate condition, and to rapidly energize the motor clockwise and counterclockwise to respond to a jammed condition or stuck float condition.
Abstract: Motor speed, motor amps, float position and elapsed run time are monitored to determine whether a sump pump is in a normal condition, a jammed condition, an inadequate pumping rate condition, a dry running condition or a stuck float condition. A processor is configured to increase the motor speed in response to an inadequate pumping rate condition, and to rapidly energize the motor clockwise and counterclockwise in response to a jammed condition or a stuck float condition. The processor provides signals to a display for displaying information about the condition that the pump is in. The pump is set up to receive power from either an AC power source or a battery power source. Availability of the AC power source is monitored and the pump is switched to operate from the battery power source when AC power is unavailable.

TL;DR: In this paper, an apparatus and a method for monitoring and controlling a motor driven sump pump is presented, which includes a power supply which powers the apparatus, a sensing portion which detects the level of the liquid within the sump, a control portion which turns the motor either off or on in response to the level, and an alarm portion cooperating with the sensor which activates an alarm when a preselected level has been reached.

TL;DR: In this paper, the authors describe a dryer with a rotating drum having an inlet (14) and an outlet (14B) and a blower (15) withdraws air from the outlet, which is coupled to the inlet of the evaporator and is thermally coupled to a wet air heat exchanger.
Abstract: A dryer includes a rotating drum (14) having an inlet (14A) and an outlet (14B). A blower (15) withdraws air from the outlet. A heat pump has an evaporator (17) and condenser (25) interconnected by a compressor (26) and an expansion valve (27). The outlet of the condenser is connected to the inlet of the rotating drum. The water collection tray (21) drains into a sump (23) having a sump pump (24). In a closed loop form the outlet of the rotating drum is coupled to inlet of the evaporator and is thermally coupled to a wet air heat exchanger (16).

TL;DR: A pump control and management system for monitoring and controlling sump pumps as well as providing supplemental controls and alarms is described in this paper. But this system requires a sump pump, a level sensing assembly, a control assembly, and at least one local sensor.
Abstract: A pump control and management system for monitoring and controlling sump pumps as well as providing supplemental controls and alarms. The pump control and management system includes a sump pump, a level sensing assembly, a control assembly, and at least one local sensor. The sump pump is designed for pumping water out of a sump pit. The level sensing assembly is preferably positioned within the sump pit for detecting a level of water in the sump pit. The control assembly is electrically coupled between an electrical service connection and the sump pump. The control assembly monitors electrical current drawn by the sump pump. The control assembly is also operationally coupled to the level sensing assembly. The control assembly activates the sump pump when the level sensing assembly signals that water in the sump pit has reached a predetermined level.
