MARK devices

Intralox conveying belts for easy maintenance and excellent belt guiding with metal detectors and chalk marking device for marking of metal-contaminated slabs... 

Marking devices are available which impress identification into the surface of the unvulcanised rubber slabs. Other devices can continuously apply an identification to extrudates on emergence from the die. 

Fig. 1. An overview of the DCLD tier/triage flow chart Boxes 1, 2, and 3 are taken from the Office of Device Evaluation decision tree, which is routinely used to determine whether a product can be reviewed as a 510(k) and found substantially equivalent to a predicate (currently marked) device or whether the product must be handled as a fundamentally new product and submitted to a PMA review. Box 4 determines the novelty of the product in terms of analyte, matrix, and/or technology. If new issues of safety and effectiveness are raised, a highly novel product might require review as a PMA. If the issues of safety and effectiveness are not new but require high-level scrutiny, then a tier III review is warranted. Examples of products requiring a tier III review would include 1. Analyte troponin for diagnosis of MI (with creatinine kinase as the predicate) 2. Matrix sweat patches for drugs of abuse (with urine drugs of abuse tests as the predicate) and 3. Technology nucleic acid...

Clinical investigation will also be required where a CE marked device is to be used for a new purpose.

Because the Nd YAG laser is the preferred marking device for developing high contrast marks on a dark substrate, development of a specialty lasermarkable grade of acetal copolymer was focused on that laser type. In particular, the objective was to develop a lasermarkable black formulation that yields the highest possible contrast when marked with the Nd YAG la-...
