Abstract: A highly compact and lightweight exercise machine which, in one unit, includes the features of a bicycle ergometer and of a rope pulling machine. The resistance to the movement of the bicycle ergometer and rope pulling machine features is provided by the same resistance apparatus. The resistance apparatus includes a metallic disk which is connected to the bicycle ergometer and rope pulling features and which rotates near a source of magnetism. The interaction between the rotating disk and the source of magnetism creates electromagnetic forces which exert drag on the disk. The exercise machine is constructed so that all rotatable components require only two shafts, which construction significantly reduces the space requirements of the exercise machine components. A differential pulley system is incorporated in the exercise machine and amplifies the resistance produced by the resistance apparatus.

Abstract: The exercise machine of the present invention is comprised of articulated arms which can be moved between retracted cocked positions and extended punching positions in order to simulate the throwing of a punch. The upper portions of the arms are in the form of parallelogram linkages which allow them to be moved between extended and retracted positions at their point of connection with the body of the machine. A shoulder, which rotates about the post which supports the machine activates the parallelogram linkages so as to extend the arm attached to the side of the shoulder which is moved forward and retract the arm on the side of the shoulder which is moved rearward. A motor, which causes the shoulder to rotate is activated by a control system. A microprocessor associated with the control system permits the machine to be preprogrammed to throw a series of punches in particular combinations to give the appearance of an actual boxer.

Abstract: A fencing sword, especially an epee or a foil, whose blade is provided with at least one groove defining a strain concentration zone, dimensioned to rupture longitudinally to separate two longitudinal parts of the blade from one another so that, with subsequent impacts, there is a change in the nature of the sound generated by impact. The rupture occurs when the metal fatigue reaches a point at which transverse rupture might be expected so that the sound change can inform the user of the need to discard the blade.
