DEFINITION

Classification: 406/10

WITH MEANS TO CONTROL CONVEYING FLUID OR MOVEMENT OF LOAD IN RESPONSE TO SENSED CONDITION:

(under the class definition) Subject matter wherein a step or means is provided for: (a) detecting any of the following characteristics: a state or property or change therein, or the random occurrence of a predetermined event in any of the following: the fluid conveyor* or a device associated therewith, the conveying fluid, load, or the immediate environment of the conveyor* affecting the operation thereof; and (b) regulating a (a result of such detection) the movement of the load or conveying fluid.

(1) Note. This definition requires a patent to claim at least 3 discrete instrumentalities for original placement herein. One of these must be a fluid conveyor*. The other 2 are: (a) a sensor (e.g., thermocouple, photocell system, etc.) to detect a condition as stated in (a) of the definition, and (b) a controller (e.g., pump motor, valve, solenoid, etc.) to regulate movement of the load or conveying fluid.

(2) Note. "Regulating" as used above includes initiating or terminating.
