Biorhythmic slide rule

Claim 1

A biorhythmic slide rule comprising: a housing having a guide track assembly, said guide track assembly comprising three (in number) separate adjacent parallel guide tracks, there being a separate said slide located within a separate said track, said housing having a front side, a first sequential indicia located on said front side; a member movably mounted on said housing, said member having a thin hairline the longitudinal axis of which is located transverse to the longitudinal arrangement of said first indicia; a first substantially transparent slide and a second substantially transparent slide and a third substantially transparent slide being movably mounted within said guide track assembly, each said slide including a different opaque sine wave curve, said sine wave curve being observable through said front side of said housing in an overlying relationship, each said slide having a sequential series of numerical indicia arranged adjacent its respective said sine wave curve, each said numerical indicia having an established upper limit correlated to its respective said sine wave curve with said upper limits being different, each said numerical indicia comprising a series of opaque evenly spaced apart first marks, the spacing between each of said first marks being identical for each said numerical indicia, said hairline to be alignable with said first mark of each said numerical indicia; and handle means attached to each said slide to facilitate sliding movement and positioning of each said slide within its said guide track assembly, said handle means comprises a longitudinal extending member located at each longitudinal end of each said slide, with said slide located in an overlying relationship the said extending members at each said end being located in a staggered relationship in respect to each other.
