  • Patent number: 4451416
    Abstract: A flowable slidifyable mass is applied onto the inner surface of a hull made of an elastomeric material and corresponding to the human skin section. This flowable mass is let to solidify into a shell-like body. Thereafter the shell-like body is cut and machined such to produce an article corresponding in shape to a portion of the human skeleton. A molding mass which solidifies to a flexible body is injected into the void space defined by the elastomeric hull stretched over the skeleton portion such that a flexible negative form of the skeleton is produced. Thereafter the elastomeric hull, the negative form and the skeleton portion are separated from each other and the elastomeric hull stretched over the negative form only and a further molding mass is inserted into the void spaces defined by the elastomeric hull and the negative form such that an arbitrary number of skeleton portions can be produced.

  • Patent number: 4402472
    Abstract: A winding and reeling device for an elongated, flexible member. A reel is connected to the outer end of a spiral spring. The outer end of the spiral spring is rigidly connected to the reel, whereby a gear is connected between the outer and the inner end of the spiral spring such that upon rotation of the outer end of the spiral spring around its center axis the inner end of the spiral spring rotates around the same axis, however at a slower rotational speed. The reel has smooth surfaces and comprises at no place any gear teeth. A rotation of the reel causes the rotation of the gear wheels of the gear, whereby two gear wheels having a different number of teeth are rigidly connected to each other and arranged on a common shaft. A further shaft is provided which carries two further gear wheels, whereby one gear wheel is rigidly connected to the further shaft and the other gear wheel is freely rotatable on said further shaft.
