Abstract (en)
The device has a pallet assembly (4) with a portion (4a) receiving a slot (18), where the portion is made of a shape memory alloy which undergoes reversible transformation from an austenitic crystallographic phase to a martensitic crystallographic phase. The portion does not hold a pallet (14) in the martensitic crystallographic phase so that the pallet is displaced in housing. The portion holds the pallet in the austenitic crystallographic phase, when the portion is at an ambient temperature. An independent claim is also included for a process for fixing a pallet on a pallet assembly.
