Abstract:
1. An apparatus for creating a visual impression of a fluid flowing in an enclosed fluidless hollow channel possessing a first end and a second end, comprising: a hollow helical shaft positioned between said first end and said second end within said hollow channel; an electric motor to rotate said hollow helical shaft within said hollow channel; and an electrical power supply to power said electric motor in rotating said hollow helical shaft to create said visual impression, said electrical power supply further comprising a switch controlling said electric motor; wherein said hollow helical shaft seen within said hollow channel has a color similar to said fluid; a coupling of said hollow helical shaft between a user control located near said cylinder first end and said switch located near said cylinder second end; wherein said user control operates in a member of the user control collection including at least a first control state and a second control state; wherein whenever said user control operates in said first state, said hollow helical shaft coupling puts said switch into said off-state; and wherein whenever said user control operates in said second state, said hollow helical shaft coupling puts said switch into said on-state.
