According to the present invention, methods of marking in a substrate comprises placing one or more than one magnet adjacent to a substrate while it is being powder coated or after it is powder coated and while the coating is uncured, thereby orienting a magnetic pigment with the magnet having a desired shape to form a desired marking, followed by heating or curing to form a coating film. In another embodiment, the present invention provides marked powder coated substrates in a variety of shapes comprising one or more than one marking formed by orienting a magnetic pigment or interference pigment in a powder coating or by orienting an interference pigment in a liquid coating. In yet another embodiment, the present invention provides markable powder coating compositions comprising magnetic pigments, as well as powder coating compositions comprising interference pigments, such as color shifting pigments.

摘要:
A method and apparatus for desorbing processing liquid from a processing liquid delivery line is provided. Non-thermal energy, such as ultrasonic energy or electromagnetic energy, is applied to a processing liquid delivery line. The non-thermal energy may be applied directly to the processing liquid delivery line, or may be applied indirectly via a conducting medium which distributes the energy along the length of the processing liquid delivery line. When non-thermal energy in the form of electromagnetic energy is employed, the frequency of the electromagnetic energy is adjusted to match the vibrational frequency of the absorbed molecules of processing liquid.

Differences in the physical and chemical properties of synovial fluid from healthy and arthritic joints are detected by infrared spectroscopy. A beam of infrared light is directed at a sample of synovial fluid (either in its native form or prepared as a film) and changes in the physical and chemical properties of the fluid being analyzed are detected at one or more wavelengths to determine whether changes in the position, width, absolute intensity, relative intensity or shape of the infrared absorption have occurred which are characteristic of the arthritic condition.
