Abstract

651,756. Indicators for displaying variable information. McLAUGHLIN, W. March 18, 1948, No. 8096. [Class 118 (i)] [Also in Group XV] An indicator for use in calculations relating to thermodynamics comprises a disc a having a series of circumferentially-arranged headings relating to thermodynamics and radially arranged formulµ covering equations used in solving questions relating to the heading under which they appear, and a mask b with a slot c thereon and rotatable with respect to the disc a so that any formula required can be exposed through the slot c. General information relating to thermodynamics may be provided on the back of disc a and front of disc b.
