A label has a topcoat layer and a sacrificial layer. The topcoat layer has a first color having a first L-value and the sacrificial layer has a second color having a second L-value. The topcoat layer comprises at least one reflective pigment and a polymeric binder and the sacrificial layer comprises at least one infrared (IR) absorbing material and a polymeric binder. The first L-value is greater than the second L-value, and the total amount of the at least one reflective pigment is from 40 wt % to 80 wt %, based on the weight of the topcoat layer.

The invention relates to a machine for labeling “blank-labeled” cryogenically-frozen vials or ampoules, which contain heat-labile biological materials, and to which a laser-light sensitive material had been applied prior to freezing. Accordingly, the machine has been designed to maintain the integrity of the biological materials throughout all phases of the labeling process. The machine generally comprises a master control system; a programmable user interface; a frame; cryogenic freezer assemblies, for keeping the vials at the required low temperatures; an infeed assembly, configured to receive and position blank-labeled cryogenic vials; a cryostatic labeling/quality control tunnel, wherein the vials are maintained at the required temperature, labeled by laser ablation, and checked for quality; and, an outfeed assembly. The machine further comprises a means for transporting the vials from the infeed assembly to the tunnel, and from the tunnel to the outfeed assembly. Vials labeled according to the instant disclosure are ultimately manually or automatically loaded into cryogenic shipping containers.

A laser marking system comprises at least one controller to control an array of optical devices, between a laser source and a scan head. The array applies a selected pattern of portions of the received spatial profile of the laser beam to the substrate to achieve a second intensity different from the first intensity of laser beam at a rate of power deposition relative to a rate of thermal diffusion in the substrate for a predetermined time interval to thermally heat locations of the substrate with the selected pattern of the portions. The second intensity effectuates carbonization of materials of the substrate to create a mark without ablation.

A method of printing a decoration on a substrate include inkjet printing a plurality of inks to form a layer having a predetermined pattern on a surface of the substrate, wherein each of the inks includes a solvent and has a different color; heating the substrate to evaporate at least a portion of the solvent in each of the plurality of inks; and thermally curing the layer after evaporating at least the portion of the solvent in each of the plurality of inks to form the decoration. The substrate is heated to a temperature that evaporates at least the portion of the solvent in each of the plurality of inks without fully curing the plurality of inks. A boiling point of the solvent in each of the plurality of inks is within 10° C. of each other.

This invention relates to an apparatus and method for applying writings and other markings to a frozen vial or ampoule, which is filled with biological material, and which is held at temperatures between about −70° C. and about −196° C. More particularly, the invention relates to a laser marking method that allows frozen vials to be labeled, while maintaining the integrity of the biological material contained therein.

A method is provided for producing a glass or glass ceramic article that includes: providing a sheet-like glass or glass ceramic substrate having two opposite faces, which in the visible spectral range from 380 nm to 780 nm exhibits light transmittance of at least 1% for visible light that passes from one face to the opposite face; providing an opaque coating on one face where the coating exhibits light transmittance of not more than 5% in the visible spectral range from 380 nm to 780 nm; and directing a pulsed laser beam onto the opaque coating and locally removing the coating by ablation down to the surface of the glass or glass ceramic article, repeatedly at different locations, thereby producing a pattern of a multitude of openings defining a perforated area in the opaque coating, so that the opaque coating becomes semi-transparent in the area.

Disclosed are a method of manufacturing a non-slip plate and a non-slip plate manufactured thereby. The method includes preparing a base metal plate for joint design, washing and surface treatment, preparing a non-slip material, adhering the non-slip material to the bonding surface of the base metal plate to form a protrusion, and brazing the base metal plate having the non-slip material adhered thereto in a brazing furnace. The non-slip plate is applied to vehicles to impart non-slip performance thereto, and can be semi-permanently used.
