Title: Stepless variable speed transmission - uses eccentrically mounted tapered friction discs with self-induced end load
IPC: F16H15/14
Filed: 1974-12-30
Abstract: A stepless variable speed drive has an input shaft with a splined end carrying three tapered discs.

Title: Electronic control for fuel injection system - has circuit to measure air flow to determine quantity of fuel required
IPC: F02D41/10
Filed: 1975-06-26
