Abstract: A packing or unpacking machine having conveyor tracks for articles and containers, with transfer units that are guided in a circular path above these conveyer tracks. Each of the transfer units has a pick-up and carrier head on a support element that can be raised and lowered. A movement mechanism is provided for generating a relative movement for the pick-up and carrier heads relative to the support elements, with this relative movement being superimposed over the rotational movement of the support elements, so that during respective rotation of the support elements, which follow the circular path, the pick-up and carrier heads are moved in a common elliptical or elliptical-like overall path of revolution. In so doing, the respective pick-up and carrier heads are moved about a vertical axis such that a constant parallel position is maintained relative to the conveyer tracks. In this way, not only are the pick-up and carrier heads moved in the transport direction of the conveyer tracks for a period of time that is sufficient to permit reliable pick-up or depositing of the articles, but also a smooth, quiet rotation of the pick-up and carrier heads in the overall path of revolution is achieved.

Abstract: An erasable optical data storage medium has a polymer dual recording layer (10) including an expansion layer (14) bonded to a retention layer (16), each of the layers dyed to selectively absorb light in respective narrow wavelength bands. The retention layer (16) has a glass transition temperature substantially above the glass transition temperature of the expansion layer (14), and is capable of undergoing substantial viscoelastic shear deformation (22) while below its glass transition temperature. A first laser beam B1 heats the expansion layer (14) causing it to expand and cause viscoelastic deformation in the retention layer (16) while the retention layer (16) is below its glass transition temperature. A second laser beam B2 is used to heat the retention layer (16) above its glass transition temperature and relax the deformation (22), erasing the medium.
