Abstract: A gaming machine includes a housing, in which a game sequence controller, at least one display device for displaying a gaming unit and at least one switching element, actuatable by a user and in contact with the game sequence controller, are arranged. At least one electromagnetic device coupled to the game sequence controller is associated with the switching element and, if the switching element is actuated, generates information that can be detected tactilely by the user in the form of a change of position and/or shape depending on the course of the game.

Abstract: A gaming machine including at least one computer-controlled game device, which is connected to a game progress controlling device, wherein a device is provided for controlling the input and output elements. The device has a control device which is coupled to the game progress controller and is in communication with a master, which communicates in real time via a two-wire connection with input and output elements designed as slaves.

Abstract: A bubble-blowing doll has a body which includes a trunk, two arms and two legs movably connected to the trunk, and a head also connected to the trunk and having a mouth opening. One of the arms rotates a ratchet wheel of a ratchet mechanism which, in turn, rotates a pulley about which a rope is wound during the operation of the ratchet mechanism. A bellows is mounted in the trunk, its upper end being stationary and its lower end being movable toward and away from the upper end, and the rope is connected to the lower end of the bellows, while a spring biases the lower end away from the upper end of the bellows. A conduit communicates the interior of the bellows with the interior of a balloon an open end of which is mounted on a reed and a distensible end of which is located at a free end of the reed and at the mouth opening of the head in a deflated condition, and at the exterior of the head next to the mouth opening in the inflated condition of the bellows.
