ABSTRACT OF THE DISCLOSURE Disclosed is a detector for indicating visually or by providing a warning signal as to the amount of chemical degradation suffered by a pressurized or unpressurized oil or lubricant containing negatively charged sulfur ions that has been exposed to elevated temperature. In its visual form detector (20, 20A) has . a portion (1, 1A) made from material able to provide positively charged copper ions when emersed in the oil or lubricant and has sufficient mass to support a coating (9, 9A) that is a reaction product of the positively charged copper ions and the negatively charged sulfur ions. The detector in the form of detector (20B), 20C) is also able to provide a warning signal (17) by opening an electrical circuit (19) as a result of having a portion (1B, 1C) made from a positively charged copper ion producing material of sufficient mass that enables the material to be eroded by sulfur containing acids sufficiently to open the electrical circuit.
ABSTRACT A no-flow vacuum control signal valve (10, 60) employing a single solenoid coil (34, 116) having a stationary ferromagnetic core (40, 68) and moveable permanent magnet armatures (46, 48, 100, 108) disposed adjacent the opposite ends of said core. The permanent magnet armatures function as individual valve poppets for individually opening and closing a vacuum vent port (18, 96) and a vacuum source port (28, 88) communicating with a valving chamber (14, 78, 80). A spring (50, 52, 104, 112) biases each poppet closed such that no fluid flows when the coil is not energized. Upon pulsing with current of one polarity of the coil, the vent port remains closed and the vacuum source port is opened. Upon pulsing of the coil with current of reverse polarity, the vent port is opened and the vacuum source port remainss closed. The valving chamber has a third fluid signal port (32, 98) adopted for connection thereto for control signal output.

ABSTRACT OF THE INVENTION: A water fill control system for a dishwasher having a solenoid actuated water inlet valve electrically in series with pump motor for recirculating wash water. The pump inlet is connected to receive tub water head and pump discharge is applied to a sensing disphragm to actuate a movable pole piece for defeating solenoid primary armature operation when the solenoid coil is energized. The solenoid employs a secondary armature operative only in response to the coil experiencing locked rotor current in the pump motor. When the solenoid coil is energized for normal water inlet operation, either normal wash water pressure from the pump outlet or a locked pump rotor will effect closing of the water inlet valve.
