Richard Green of the Wycombe Test Group, High Wycombe, Bucks. UK designed and tested an auto release and offered to sell me one back in 1980. His long hand letter to me said that he was "an old age pensioner" so maybe he and his BGA certified release are something of history.
The engineering blue print of it is 3X2 feet in size, but a side view is on a normal size sheet of paper which I'd be happy to send to anyone. A Schweizer release is attached to the device which essentially operates when the angle up exceeds a certain limit.
He said the club made over 1000 tows with it and there were no "spurious releases."
