Abstract: ABSTRACT OF THE DISCLOSURE     An injection molding machine includes a mold closing unit which is adapted to selectively accommodate injection mold assemblies having injection openings with different axes.  Accordingly, the injection molding unit of the injection molding machine is capable of selectively assuming a plurality of working positions.  Each working position is associated with an injection axis.  A first working position is assumed in case the mold assembly held by the mold closing unit has a central injection opening, in which case the injection in that working position occurs in a central injection axis.  The other working positions are associated with off-center injection axes to be associated with cor-responding off-center injection openings of other mold assemblies.  The stationary mold carrier of the mold closing unit has a throughgoing aperture through which a frontal part of the injection molding unit projects when brought into operative engagement with the mold assembly held in the mold closing unit.  The injection molding machine includes a transposing unit which shifts the injection molding unit parallel to itself into the selected working position, in a direction transversely to the parallel-extending injection axes.  The mold cavity of the mold assembly having an off-center injection opening is so arranged that the center of mold separating forces generated during injection will lie approximately in the central axis of the mold assembly.

Abstract: REVERSIBLE RESISTANT DEVICE                ABSTRACT OF THE DISCLOSURE       A reversible resistant device having the property of being normally non-conductive, but being adapted to being converted to the conductive state.  This change in conductive state is achieved by subjecting the device to a high voltage or high electric field.  The essence of the device is a normally non-conductive film located between conductive layers, the film being formed by metal oxide coated metal particles embedded in a binder.  A conductive film is located intermediate the normally non-conductive film and one of the conductive layers, the conductive film comprising metal particles dispersed within a second binder.          When subjected to a high potential, the metal oxide coating looses its dielectric properties and renders the film conductive.
