Abstract: In some examples, a machine for generating optically variable image elements on a substrate includes a printing substrate infeed and a printing unit including a printing mechanism by which a substrate guided on a transport path is printed with a coating agent containing magnetic or magnetizable particles. A device for aligning the magnetic or magnetizable particles includes a first alignment device in the transport path and a further alignment device arranged upstream therefrom. During normal operation, the further alignment device is fixed to a frame at the transport path. The further alignment device includes a plurality of magnets that are spaced apart from one another transversely to the transport direction and, during operation, remain stationary. The number of magnets included in the further alignment device correspond to a number of columns of image-producing print motifs or groups of image-producing print motifs around a circumference of a forme cylinder.

Abstract: A utility knife includes a body with a knife blade storable within the body and one or more magnets coupled to the knife body. The magnets are able to be embedded within the body or embedded with an adapter that is configured to removably couple with the utility knife. In some embodiments, the knife blade folds out from a side of the body and into an operable position. Alternatively, in some embodiments, the knife blade slides out of a top of the body and into the operable position. The utility knife is able to magnetically couple with a base having a magnetically attractable surface. The utility knife is securable to the base in a vertical orientation and a horizontal orientation.

Abstract: The present invention relates to a method of delivery of a therapeutic agent to a target cell the method comprising targeting particles comprising the therapeutic agent to the cell using magnetic means to apply a magnetic force to said particles so as to tend to move said particles towards said magnetic means and at the same time moving said magnetic means.
