The present invention is directed to a spacial logical toy having a total of twenty-six toy elements mounted on a spherical internal connecting element. The toy elements are assembled to a spacial body having an octagon cross section on any of the three mutually perpendicular axes. The surfaces of the twenty-six toy elements that make up the geometric solid are provided with one of three colors and are sequentially numbered (1-26) or lettered (A-Z) to provide each surface with a unique designation. The twenty-six toy elements are mixed by rotation of any adjacent nine elements relative to the remainder of the geometric solid. The objective or solution is to return the toy elements to an original sequential orientation.

The present invention provides a tamper-resistant fluid-operated brake actuator having a power spring housed within a head or cap which is attached to a flange case having one or more diaphragms or pistons responsive to changes of fluid pressure within the brake actuator chambers. In one embodiment, the head is attached to the flange case by a substantially continuous curvilinear annular metal retaining member which must be inelastically deformed or destroyed in order to remove the head from the flange case, thus rendering tampering more difficult. In another embodiment, the annular metal retaining member of the present invention is integral with the actuator head and which is metal-spun or the like onto the flange case.
