MUMBAI, India, May 29 -- Intellectual Property India has published a patent application (202641044222 A) filed by Aditya University; Aditya College Of Engineering And Technology; Aditya College Of Pharmacy; and Aditya Degree College, Surampalem, Andhra Pradesh, on April 7, for 'a measuring tool for radius of spherical surface with tangential contact and method of operation.'

Inventor(s) include Billa Suresh Kumar; Dr. Abbireddy Sridhar Reddy; Koduri Nagarajani; Dr. Kudipudi Venkateswarlu; and Dr. Korupolu Nagu.

The application for the patent was published on May 29, under issue no. 22/2026.

According to the abstract released by the Intellectual Property India: "The present disclosure proposes a measuring tool (100) for determining the radius of a spherical surface (10) through tangential contact and angular displacement to obtain a direct radius indication. The measuring tool (100) comprises a shank (102), a primary jaw (106), secondary jaws (110A, 110B), a pointer (112), a fulcrum pin (118), pivot holders (111), pivot hooks (114), and fasteners (116). The measuring tool (100) operates without electronic sensors, signal processing units, or computational devices. The measuring tool (100) provides repeatable measurement based on a fixed relation between angular displacement of the primary jaw (106) and the radius of the spherical surface (10). The measuring tool (100) is utilized in manufacturing and inspection processes involving spherical surfaces (10). The measuring tool (100) determines the radius of the spherical surface (10) without measuring diameter."
