Dietary balance giving total amount of e.g. calories in meal - has each food container fitted with rod pushing against counterweighted plate of balance moving against scale giving direct read-out

摘要

The balance is used to measure directly, without calculation, the total amount of calories or of sugar contained in several food products measured together. Each food product is placed in a container which is positioned on the balance according to the number of calories it contains per 100 g. Each container is fitted at its bottom with a rod which pushes on the plate of the balance. This plate is balanced by a counterweight which can be placed at a variable distance from the balance plate. The counterweight gives, as a function of its position the total number of calories contained in the meal formed by the several food products placed in the containers.
