Abstract: A three dimensional sliding element puzzle having a surface that is spherical in shape. The sphere is divided into longitudinal segments and latitudinal bands of surface elements. The puzzle is solved by rearranging the surface elements. The surface elements are rearranged by latitudinally rotating latitudinal bands of elements, and are rearranged by rotating hemispherical sets of longitudinal segments. The surface elements may have a pattern, color or numeric coding to indicate when they are arranged in a solution set. The surface elements may also be imprinted so that the solution is a map of the earth or another globe. The surface elements may also be designed to have a number of configurations forming a number of possible solutions.

Abstract: A data entry device having five keys, not in one plane, is held in and operated by one hand. Each key has two "on" positions and one "off" position. By using a single key or chord of keys to form characters, a surplus of possible combinations is generated. Because it is grippable and requires only one hand to operate, the user can utilized it while simultaneously walking, writing, reading, commuting, using a phone, holding a conversation, or engaging in related and unrelated activities.

Abstract: A one piece binder for perforated sheets, including a base portion and at least a ring. The ring comprised two members which, when locked, present a smooth and continuous surface and, when unlocked, are spring-biased apart. The locking means on one ring member terminates in resilient guide and latching portions which are received in an apertured portion of the other member.
