ABSTRACT:
A weighing instrument for the analysis of the weight-related characteristics of different materials has a pointer rotated about an axis in response to the weight of the material and which indicates a selected characteristic of the material on a selected graduated scale carried by an interchangeable slide. In the preferred embodiment, the weighing instrument is part of a diet control system also including an organized set of interchangeable slides each of which carries a number of concentric scales graduated in calories for respective food or drink items in a related food group. To facilitate handling of the slides, the slides are rigid and rectangular, and the weighing instrument has a rectangular slot for receiving and holding the slides under the force of their own weight. The pointer is protected by being carried on a circular disc and being covered by a viewing window which also serves to define the rectangular slot for receiving the slides. The slides are conveniently arranged in a horizontal stack which may be indexed according to major food groups. The slides in the stack are readily identified by generic names imprinted on the top edge faces of the slides.
