Abstract: The invention relates to a mechanical sprung anti-backoff device, capable of fixedly immobilizing or releasing a manual control handwheel (4) and a motor acting on one and the same rotation shaft, comprising a cylindrical spring (7, 16), a cylinder (9, 17) mounted so as to rotate on the rotation shaft, the spring being able to rotate with the cylinder, turns of the spring being in contact with a surface of the cylinder and its ends being capable of coming into contact with the handwheel. The ends of the spring (7, 16) are curved inward or outward, the handwheel (4) may act on the curve of one or other of the ends of the spring (7, 16), and the rotation of the spring (7, 16) is limited by a stop acting against one or other of the ends of the spring. Application can be to manual control and motorized control valves, for example on fluid pipes.

Abstract: The method of the invention provides a process for a player to deploy cards in a card game. In particular, the invention provides a method for controlling the deployment of cards. In accordance with one embodiment of the method of the invention, character cards are divided into two groups. One group of character cards includes all the common cards. The common cards represent characters that there are “lots of” in a universe. A second group of character cards includes all the unique character cards. A unique character card may be stackable. A unique character card that is stackable indicates that multiple copies of that unique character card may be used in a particular fight, mission, location or any other event, depending on the particular card game. Alternatively, the common character cards may be stackable. Further, all cards in a playing deck of cards may be stackable, as is desirable, to control the use or deployment of the cards.
