Patent FR-2025732-A1 (FR)
IPC: A63C9/08
Filed: 1969-10-13
Abstract: A safety binding device for a boot on a ski has a jaw to hold the sole of the boot against the ski elastically. A latch controlled by an elastic element limits the maximum force supportable by the jaw before it is unlatched to release the boot. The device has at least one ramp against which a friction member is elastically supported to absorb a certain energy whose level increases simultaneously with the increase in the displacement of the jaw before the force exerted by the boot reaches the unlatching value of the elastically controlled latch. A roller or ball is arranged to come into action at the unlatching value of the force, thereby eliminating the action of the friction member. The ramps may be straight or curved. The friction member can be a ball, roller or sliding wedge. Manual release and resetting levers may be incorporated.

Title: Multichamber treatment furnace - esp contg vacuum chamber has transfer devices which move in one direction only
IPC: C21D1/74
Filed: 1972-07-03
Abstract: The furnace comprises two chambers separated by an intermediate chamber or lock so that the two chambers can be operated under different pressures and/or different atmospheres; two transfer devices are used, respectively for transferring from the first chamber to the lock and secondly from the lock to the second chamber. The first chamber is isolated from the lock by a valve plate which, in the closed position, fits tightly against a perimeter wall of the first chamber and, in its open state, moves away from this wall towards the opposite wall of the lock. In this second position, it is nearer to this opposite wall of the lock then to the peripheral wall of the first chamber. Pref. the second chamber is a vacuum treatment chamber and the first transfer device is fixed to the valve plate and travels with it; thus, as the valve plate is moved to open the first chamber into the lock, the material in the first chamber is moved with it into the lock chamber.
