Abstract
Abstract The weighing instrument has a receiving tray and an index mark displaceable in front of a fixed dial graduated in weight. It comprises means enabling the user to place, in a position enabling it to operate in association with said index mark, any one of several removable scales which are calibrated, for categories of foods of similar characteristics, in at least one of the magnitudes involved in dietetics and proportional to the weight of the foodstuffs placed on the tray. The instrument is useful in feeding in cases of obesity, diabetes, low calorie, low sugar, low protein, low fat or low residue, etc. diets.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
230 words
Weighing instrument having a receiver tray for foodstuffs movable with respect to a body and an index mark displaceable along a predetermined path on a housing carried by said body in front of a first scale marked in weight and fixed with respect to said housing as well as in front of a plurality of second scales marked in at least one magnitude involved in dietetics and borne by a flexible strip on which they are succeeded by categories of foodstuffs, this magnitude being proportional to the weight of foods and the position of said flexible strip with respect to said housing being adjustable at will to operate selectively in association with the index mark that of its second scales which corresponds to the category of foodstuff to be weighed, the flexible strip being guided by a plurality of parallel rollers of which one at least is provided with control means enabling it to be rotated selectively to make the various second scales move in front of the index mark along a path substantially perpendicular to said predetermined path of said index mark, the housing including means for receiving selectively and removably, between said predetermined path of the index mark and the flexible strip, one card provided with third scales arranged to cooperate with said index mark and selected from a plurality of cards each corresponding to a particular foodstuff.
Claim 2
Dependent Claim
230 words
Weighing instrument having a receiver tray for foodstuffs movable with respect to a body and an index mark displaceable along a predetermined path on a housing carried by said body in front of a first scale marked in weight and fixed with respect to said housing as well as in front of a plurality of second scales marked in at least one magnitude involved in dietetics and borne by a flexible strip on which they are succeeded by categories of foodstuffs, this magnitude being proportional to the weight of foods and the position of said flexible strip with respect to said housing being adjustable at will to operate selectively in association with the index mark that of its second scales which corresponds to the category of foodstuff to be weighed, the flexible strip being guided by a plurality of parallel rollers of which one at least is provided with control means enabling it to be rotated selectively to make the various second scales move in front of the index mark along a path substantially perpendicular to said predetermined path of said index mark, the housing including means for receiving selectively and removably, between said predetermined path of the index mark and the flexible strip, one card provided with third scales arranged to cooperate with said index mark and selected from a plurality of cards each corresponding to a particular foodstuff.
Claim 3
Dependent Claim
14 words
Weighing instrument according to claim 1, wherein the flexible strip is an endless band.
Claim 4
Dependent Claim
26 words
Weighing instrument according to claim 1, wherein the flexible strip has its ends, which are wound respectively on two rollers, each provided with a manipulating member.
Claim 5
Dependent Claim
28 words
Weighing instrument according to claim 3, wherein the rollers provided with manipulating members are equipped with dismountable bobbins, enabling the flexible strip to be replaced by another one.
Claim 6
Dependent Claim
97 words
Weighing instrument according to claim 1, wherein the index mark is constituted by a straight line, borne by a plate movable in translation in its own plane, in a direction perpendicular to the line of the index mark, and wherein the scales borne by the flexible strip are rectilinear and parallel to the axis of translation of the plate and to the axes of the rollers, the assembly being arranged such that a flat portion of the strip is presented taut behind the line of the index mark, parallel to the plane of translation of the plate.
Claim 7
Dependent Claim
64 words
Weighing instrument according to claim 5, arranged so that its movable index mark has greater movement, per unit weight, at light weights than at heavy weights, of the sliding weighing or cursor type, wherein the cursor is divided into two parts displaceable together for measuring relatively heavy weights until one only of the two parts is moved for the measurement of relatively light weights.
Claim 8
Dependent Claim
82 words
Weighing instrument according to claim 1, wherein the index mark is constituted by a rectilinear needle rotably mounted on a spindle, and wherein the scales borne by the flexible strip have the shape of circular arcs approximately centered, when these scales occupy their position of operation in association with the needle, on said spindle, the assembly being arranged so that a flat portion of the strip is presented taut behind the plane wherein the needle is moved and parallel to this plane.
Claim 9
Dependent Claim
60 words
Weighing instrument according to claim 7, arranged so that its movable index mark has greater movement, per unit weight, at light weights than at heavy weights, of the letter balance type, wherein parallel link-rods, which connect the vertical rod of the receiver tray to a fixed support in an articulated parallelogram, are positioned almost horizontally when the tray is empty.
