Patent GB-2103313-A (GB)
Title: Variable ratio traction drive
Inventor: JONES TIMOTHY JOHN
IPC: F16H15/50
Filed: 1982-06-11
Abstract: A variable ratio traction drive comprises four coaxial races confining a passage receiving a series of balls having point contact with each race. One race (c) is stationary and remains fixed, another race (b) is displaceable axially by means of an adjustment ring (a) and the input and output races are acted upon by respective springs (e,f.) or torque dependent devices to hold the balls in firm rolling contact with the races.

Title: Polyester production
Inventor: EL-GHATTA HUSSAIN
IPC: C08G63/80
