摘要:
The apparatus comprises a source of linearly polarized light to be propagated through the washing solution and to be diffuced by the micelles and the emulsion. Photodiodes receive the diffused light through respective analyzers oriented with their polarization directions parallel to the polarization direction of the primary light, and perpendicularly thereto, respectively. The apparatus determines the condition of the washing solution at the microscopic level by the use of variations of the polarization of the radiation diffused by the micelles and by the emulsion.
摘要:
Described is an automatic machine for washing articles in a bath containing surfactant substances. The machine is provided with a device for detecting microscopic characteristics of micelles and emulsion in the washing bath and for generating signals corresponding to such characteristics for controlling programmable means for the control of operative components of the machine.
摘要:
In a dishwasher having at least one rotary spray arm, a control device is provided for monitoring the rotation of the said spray arm. A detecting coil (8) is fixed to the machine, can be electromagnetically coupled with the spray arm (6) when it lies within a given area of its rotation stroke, and is connected in the electric circuit of a generator (9) for varying the output signal thereof when the coil is coupled with the spray arm. The output of the generator drives, through a differentiating circuit (11), a discrete integrator (12) whose binary output signal changes its logic level whenever the spray arm enters and leaves said area of its rotation stroke with a speed which is at least equal to a predetermined value. The binary signal may drive an indicator of the rotational speed of the spray arm.
