Abstract
Abstract An apparatus to convert any extremely small unnoticeable non linear expanding and contracting movement exhibited by a sensing element, such as a sensing element that expands in a non linear manner with changes in the relative humidity of an atmosphere into a greatly enlarged amplified motion. An example of this latter motion is the motion exhibited by a pointer moving along an associated scale and/or the motion of a pen moving along a chart which will provide an accurate linear indication of the percent of relative humidity being sensed by the aforementioned sensing element.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
235 words
A non linear to linear motion transducing apparatus, comprising a sensing member, the sensing member being expandable and contractable in a non linear manner with respect to associated increases and decreases occurring in the magnitude of the variable under measurement, a motion transmitting input crank connected for movement by an adjustably mounted pivot means with said sensing member at one end and mounted for rotation on a stationary pivot at its other end, a motion receiving output crank connected to a second stationary pivot, a connecting link pivotally connected at one end to the free end of the input crank and being pivotally connected at its opposite end to the free end of the output crank, and a link fixedly connected to the output crank for movement with the pivoted end of the output crank for transmitting motion that is linear with respect to changes that occur in the magnitude of said variable and wherein the sensing member is a continuous belt containing a single closed loop that is mounted solely on two spaced apart cylindrical members and a means is provided to retain a biasing force on said Sensing member as said increases and decreases in the magnitude of the variable occur and wherein the sensing member is connected for movement with a pivoted support member, and wherein the pivoted support member is comprised of an ambient temperature compensating means constructed of a bimetal.
