A block game includes thirty-six indicia blocks. Each of the blocks has an indicia face which is divided into two square faces. In each of the square faces, dots are arranged in three horizontal rows, with each row having one or two dots. Moreover, the dots on each indicia face are arranged symmetrically about an axis of symmetry of the indicia face. In play, two indicia blocks are positioned adjacent to one another in such a manner that an edge of the first square face which has one dot lies adjacent to an edge of the second square face which has two dots, or vice versa.

A control tab on a submarine or the like is angularly displaced by a remote control actuator system featuring a pair of shape-memory cables consist of a superelastic actuating cable connected to the control tab and a force generating thermoelastic cable anchored to the submarine frame. A force transmitting lever interconnects the cables and is selectively locked by a releasable locking mechanism in a position holding the actuating cable fully stretched with the control tab displaced a maximum amount from its neutral position by the displacing force generated in the thermoelastic cable in response to heating thereof by electric current conducted therethrough.

A hydrofoil stabilizer fixed to an underwater hull and provided with a pair of pivotally deflectable control flaps through which surface lift on the stabilizer is controlled, is provided with trailing edge tabs on both of the flaps that are pivotally deflected in the same direction to further offset and thereby improve recovery from surface jam inducing lift force on the stabilizer which adversely affects maneuvering control.

The present invention is an adjustable leg exercise apparatus for allowing a user to perform a leg exercise while sitting on a sitting structure, or alternatively, when standing in a modified standing position. In a first embodiment, the adjustable leg exercise apparatus includes a foot engagement member; a knee-thigh engagement member; at least one elastic resistance member; at least one foot securing mechanism for securing or locking the foot engagement member to the at least one elastic resistance member; at least one knee-thigh securing mechanism for securing or locking the knee-thigh engagement member to the at least one elastic resistance member; and a plurality of length adjustment and securing devices for securing each of the at least one elastic resistance member in any one of a plurality of predetermined adjustment positions. In a second embodiment, the knee-thigh engagement member may include a knee-thigh wrapping device.
