Abstract: The invention relates to a light prosthesis as a purely optical substitute for a missing limb, including a shaped body (1) for replacing the missing limb as naturally as possible and a socket (2) for connecting the prosthesis to the stump (3) of the missing limb. In order to provide such a prosthesis for temporary or permanent use without having to fulfil any functionality, thus being suitable also for elderly patients, it is contemplated that the shaped body (1) is made of a light synthetic material, and that the periphery of the socket (2) for connecting the prosthesis to the stump (3) is variable in a manner known per se. The shaped body (1) may, in particular, also be made of an elastic, air-tight synthetic material (9) and include at least one valve (10) for inflating the shaped body (1).

Abstract: In a printer in which a shuttle and a counterbalancing mass are driven in opposing reciprocating fashion by a rotating, generally oval-shaped cam, the cam followers which couple the shuttle and the counterbalancing mass to the cam are castered to prevent skewing of the cam followers relative to the cam. Each of the cam followers is disposed between and rotatably mounted on a pair of opposite arms extending outwardly from a generally planar base of a castered yoke assembly, the planar base being pivotally coupled to a supporting member therefor which is either coupled to the shuttle or forms a part of the counterbalancing mass. In a first embodiment the pair of opposite arms extend from the planar base toward the cam so as to dispose the cam follower between the pivotal mount of the yoke assembly and the cam.
