Abstract: Exercise apparatus (1) in which a person exercising exerts a force against a movable actuator (6) to which is applied an adjustable force by a load system which resists or assists the movement of the actuator and is connected to the actuator by cables (9). The load system comprises a fixed, longitudinally arranged coaxial series of coil units (15), each coil unit being independently connectible to a source of electric current. The series of coils provides an elongate passage (18), and a shuttle (19) of ferromagnetic material is mounted for relative longitudinal movement within the passage, in response to movement of the actuator. Passage of a current through a coil unit exerts a force on the shuttle when in that coil unit, and is controlled by a microprocessor (22).

Abstract: A clamshell carton formed from two integral blanks of sheet material. The front wall of the upper clamshell carries a latching aperture. The front wall of the lower clamshell half carriers a latch release panel, the latter carrying a horizontally despaired latching tongue normally engaged in the latching aperture to maintain the clamshell in a closed configuration. The latch release panel is normally resiliently biased to maintain the latch tongue engaged. The front wall of the upper clamshell half is provided with a recess along a free edge, the recess permitting direct finger force to be applied to the latch release panel to open the carton by disengaging the latch.
