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.

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.

A method for manufacturing a tub of ferritic stainless steel for a laundry washing machine, comprising the steps of cutting a sheet metal blank, winding the blank and welding it to the form of a cylindrical body,, expansion-forming of the cylindrical body and applying the end walls and accessory elements to the body. The welding step is carried out by means of a laser, and prior to the expansion-forming step the cylindrical body is subjected to a heat treatment for eliminating the brittleness of the weld.

摘要:
A mains-wired monitoring and security system comprises an electric supply mains network (10) having connected thereto a control unit (Figure 1), a plurality of detecting units (Figure 2), and a plurality of actuating units (Figure 3). Each unit includes associated counter means (5, 15,29) controlled in synchronism with each other. Each detecting unit transmits a coded signal (f2) along the mains network when an associated sensor (14) detects an alarm condition and its associated counter means (15) simultaneously counts a specific number N. At least one actuating unit activates an associated actuator (37) in response to said coded signal if its associated counter simultaneously counts the number N. The central unot visually displays said number N, which is common to at least one detecting unit and at least one actuating unit, in response to said coded signal.
