Abstract
Abstract A multimeter having an optical pointer capable of being switched from one scale to another in compliance with the variable to be measured and comprising an illuminating assembly with a diaphragm and an active part or movement a with movable mirror intended for directing the optical pointer onto scales, wherein the illuminating assembly of the selector type is linked to a scale changer, provision being made for the scale changer to shift the light beam emerging from the aperture of the diaphragm into different positions corresponding to the selected scale and to the light beam to fall on the movable mirror of the active part on movement at different angles, depending upon the position selected.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
189 words
A multiscale meter with a light spot formed at the end of a light beam, said light spot traveling from one scale to another according to a selected value being measured, comprising an instrument movement, a switching means to connect the selected value being measured to said instrument movement, a movable mirror attached to said instrument movement so that the angle of rotation of the mirror depends on the value being measured, a plurality of scales graduated in terms of the values being measured, an illuminating means, a diaphragM with an aperture to let the light beam pass from said illuminating means onto the movable mirror so that said mirror deflects the light beam onto one of said scales in the form of a light spot, selecting means associated with said switching means and displacing the aperture in said diaphragm relative to said mirror parallel to its axis of rotation so that by switching the light spot from one scale to another, the angles of incidence of the light beam onto said movable mirror and onto the respective scale will both simultaneously change and be equal to each other.
Claim 2
Dependent Claim
189 words
A multiscale meter with a light spot formed at the end of a light beam, said light spot traveling from one scale to another according to a selected value being measured, comprising an instrument movement, a switching means to connect the selected value being measured to said instrument movement, a movable mirror attached to said instrument movement so that the angle of rotation of the mirror depends on the value being measured, a plurality of scales graduated in terms of the values being measured, an illuminating means, a diaphragM with an aperture to let the light beam pass from said illuminating means onto the movable mirror so that said mirror deflects the light beam onto one of said scales in the form of a light spot, selecting means associated with said switching means and displacing the aperture in said diaphragm relative to said mirror parallel to its axis of rotation so that by switching the light spot from one scale to another, the angles of incidence of the light beam onto said movable mirror and onto the respective scale will both simultaneously change and be equal to each other.
Claim 3
Dependent Claim
206 words
A multiscale meter with a light spot formed at the end of a light beam, said light spot traveling from one scale to another according to a selected value being measured, comprising an instrument movement, a switching means to connect the selected value being measured to said instrument movement, a movable mirror, said movable mirror attached to said instrument movement so that the angle of rotation of the mirror depends on the value being measured, a plurality of scales graduated in terms of the values being measured, an illuminating means, a diaphragm having a plurality of apertures arranged in a row parallel to the axis of rotation of said mirror, a plurality of shutters placed near said apertures, with each of said plurality of shutters being associated with a respective aperture, electromagnetic means coupled with said switching means and having a plurality of windings and armatures cooperating with the shutters, said electromagnetic means displacing said shutters so that only one aperture is open at a time, the switching over of the light spot from one scale to another causing the angles of incidence of the light beam onto said movable mirror and onto the respective scale to both simultaneously change and be equal to each other.
Claim 4
Dependent Claim
206 words
A multiscale meter with a light spot formed at the end of a light beam, said light spot traveling from one scale to another according to a selected value being measured, comprising an instrument movement, a switching means to connect the selected value being measured to said instrument movement, a movable mirror, said movable mirror attached to said instrument movement so that the angle of rotation of the mirror depends on the value being measured, a plurality of scales graduated in terms of the values being measured, an illuminating means, a diaphragm having a plurality of apertures arranged in a row parallel to the axis of rotation of said mirror, a plurality of shutters placed near said apertures, with each of said plurality of shutters being associated with a respective aperture, electromagnetic means coupled with said switching means and having a plurality of windings and armatures cooperating with the shutters, said electromagnetic means displacing said shutters so that only one aperture is open at a time, the switching over of the light spot from one scale to another causing the angles of incidence of the light beam onto said movable mirror and onto the respective scale to both simultaneously change and be equal to each other.
Claim 5
Dependent Claim
171 words
A multiscale meter with a light spot formed at the end of a light beam traveling from one scale to another according to a selected value being measured, comprising an instrument movement, a switching means to connect the selected value being measured to said instrument movement, a movable mirror attached to said instrument movement so that the angle of rotation of the mirror depends on the value being measured, a plurality of scales graduated in terms of the values being measured, a plurality of illuminators, a diaphragm having a plurality of apertures arranged in a row parallel to the axis of rotation of said movable mirror, each aperture corresponding to one illuminator, a selecting means cooperating with said switching means so that only one illuminator is switched on at a time, the switching over of the light spot from one scale to another causing the angles of incidence of the light beam onto said movable mirror and onto the respective scale to both simultaneously change and be equal to each other.
