Abstract: The invention herein refers to a warning device (1) that has a fixation base (2), substantially cylindrical and located at the surface of a console (6) of the food preparation appliance, which also has a light source compartment (5) that has a source of light (4). A flow control button (3) is associated to this fixation base (2) which is capable of moving angularly around its geometric axis from a maximum heat position to a rest/off position, and which, through the angular movement of the flow control button (3), the light source (4) changes the color of light emitted.

Abstract: A self-propelling rolling toy includes a transparent spherical outer casing, a coupling rod provided in and coupled non-rotatably to the outer casing, a horizontal transmission shaft mounted rotatably in the outer casing, an inner body mounted rotatably on the shaft inside the outer casing, a clutch operable to lock selectively the inner body to the coupling rod, and a winding-type driving unit disposed in the inner body. The driving unit includes a spiral energy spring with an innermost end coupled to the shaft and an outermost end coupled to the inner body, a ratchet and pawl unit provided on the shaft, and a gear set which couples the ratchet and pawl unit and the coupling rod.

Abstract: A toy has a changing facial expression and includes a hollow toy body with a torso section and a head section on the torso section. The head section has a front side formed with a face opening. The torso section is provided with a pair of forwardly extending arms that are mounted pivotally on two sides thereof. The arms have distal ends that hold a shielding member therebetween, and are pivotable on the torso section between a lowered position, where the shielding member uncovers the face opening, and a raised position, where the shielding member extends across the face opening to cover the face opening. A face member is disposed rotatably in the head section of the toy body and is formed with at least two face sections. The face member can be rotated to move a previous one of the face sections from alignment with the face opening and register another one of the face sections with the face opening when the arms are in the raised position.

Abstract: A toy wheeled vehicle with an inertia wheel having friction driven wheels, an inertia type flywheel, gear trains of a driving mechanism, and a sound generator which is provided coaxially with the flywheel. The driving mechanism includes two groups of gear trains, one is for the flywheel energizing mechanism through a clutch gear and a detachable floating gear and the other is for the rotation transmission mechanism from the energized flywheel to the friction driven wheels through the clutch gear and a stationary gear which is always engaged with the flywheel gear and is detachably engaged with the clutch gear. The energized flywheel which is detached from the floating gear and the wheels through the clutch gear continues to rotate when the wheels are stopped, and when the clutch gear is engaged with the stationary gear, the inertia rotation of the flywheel is transmitted to the wheels, and the sound generator produces the sound of a siren while the flywheel rotates.
