Abstract: A highway game has a base supporting a conveyor-like roadway belt on which a toy vehicle is mounted. The vehicle has a control mechanism mounted at one end of the base and this mechanism includes a winding device wound with a tether secured to the vehicle. The roadway belt is driven in one direction by a motor to turn the wheels of the tethered vehicle and simulate movement of the vehicle in the opposite direction. The winding device of a simplified form of the game is mounted on a transverse shaft which can be rotated manually to shift the vehicle longitudinally on the rotating roadway belt. In a preferred embodiment of the game, the control mechanism is driven by a power take-off from the motor and the winding device is slidably mounted on a control shaft which is movable to engage and disengage the device from the drive so as to achieve a similar longitudinal movement of the vehicle.

Abstract: An orthodontic appliance is provided which applies a pulsating force to the tooth to be moved, rather than a continuous force as in the case with the prior art devices. The invention is predicated on the concept that when pulsating forces are applied to the tooth, there is little or no hyalinization and consequently more cellular activity, giving rise to more oesteoclastic activity for bone resorption and more oesteoblastic activity for bone opposition. Moreover, the pulsational effect of the tooth on the adjacent periodontal membrane and bone tends to loosen their fibrous structure, and helps the tooth to find a path of least resistance through the bone.

Abstract: Toys of any shape which recover their original shapes after deformation when they are heated by electrical or thermal stimulus are introduced. The deformation and shape recovery action can be repeated. The form regaining action is achieved by a special characteristics of the shape memory alloys, for example, nitinol, which change their phase and thereby change their shapes when their temperature is raised beyond their transition temperature. Toys are covered by a soft plastic to enhance the look of them.
