Abstract: A method providing for independent garment buttoning by fine motor impaired individuals involving an elongated and pointed button. This button is made of malleable plastic and its shape and length are altered to match the buttoning skill of the subject.

Abstract: A writing and display device for producing luminescent images upon application of pressure includes an opaque backing member which is coated to render the backing member with a smooth surface at least on one side thereof. The smooth surface of the backing member is laminated with a flexible plastic sheeting. A translucent or transparent sheet which contains a luminescent dye or pigment is disposed adjacent to and coextensive with the backing member. Upon application of pressure onto the sheet, the interfacing surfaces adhere to each other to thereby produce a luminescent image.

Abstract: A device for controlling the direction of rotation of a world globe. The device has a ratchet ring which is affixed to the globe near the North or South Pole thereof. A deflectable pawl member is held by the support frame of the globe and permits the globe to rotate only so that its surface moves eastwardly.

Abstract: A device for aiding and encouraging a child to brush his or her teeth regularly. The device is provided with a pair of nonrotatable shafts each of which mounts seven rotatable blocks shaped like a molar tooth, each block representing either the morning or night of a particularly day during which a child should brush his teeth. The front surface faces of the blocks form a frowning mouth with dirty teeth, while the rear surface faces form a pattern of a smiling mouth with white teeth after all of the blocks have been rotated 180 degrees. Each block is rotated to expose a portion of the smile and to remove a portion of the frown after each tooth brushing in the morning and evening of each day.

Abstract: A three-dimensional molecular model comprises plastic modules, each representing on atom connected to one another. Modules intended to represent atoms of cyclic compounds are polyhedrons set in the model so that adjacent polyhedrons touch faces and have a common apex. The sum total of the angles formed by the adjacent faces of polyhedrons of the modules is more than 360.degree..

Abstract: A device is disclosed for demonstrating the physical properties and chemical relationships between elements which includes three-dimensional models of the individual elements positioned within a chassis preferably in the same order as they are in the periodic chart. The models are magnetized spheres having model properties to indicate the size, coloration, density and electron affinity of the corresponding basic elements. The display chassis includes a plurality of retaining positions for holding the spheres and sensors for sensing the absence of the models or spheres such that an interfacing device can withdraw information from a computerized data bank for display of information concerning the element withdrawn from the chassis on a display device. Also information concerning possible molecular combinations will be displayed thereon responsive to simultaneous absence of two of the elemental models.
