Mosaic mimic display system for active and passive components A mosaic mimic display system, the Mosaic King has been introduced in the UK by Sandlaore Electrics. It is based on an aluminlum grid with plastic ~leS, and rift-ally any standard component - - push button, key switch, lamp holder, flow indicator, I.~1"), etc - - and any type of instrument no matter what shape or size can be accommodated into the system. Either 34 or 28 mm tiles can be used to make up a display, providing the flexibility to suit European DIN, NATO or Ministry of Defence specificatiom. The dimensional accuracy of each tile and the micron tolerance between them ensures that the overall size of the display is within the specified dtmex~on. Expanding the system at a future date, is a simple matter. The tiles are easy to change and can be extracted from the front with ease, but the design of the system ensures each one is securely locked into place after insertion. They are made from a self-extinguishing thermoplastic material called Makrolon, which provides, through thousands of microscopic beads, a non-reflecting, scratch resistant surface. In the event of scratching, only the tops of the beads are damaged, the paint which has been etched into the tiles remains, maintaining the image. The ahiminium grid is secured by means of a patented turn-lock system, which interlocks and secures every intersection of the gzid. The grid asmmbly is so rigid that the display structure can be made up to 4 m= without additim~ support. The system is n~imed to be the only numic dwplay avagable that can be curved without affec".-tg~s stnmgth and dimensional accuracy, while the trieswill fitneatly together without fouling or being forced out

Typical passive mosaic mimic display depicting mains HV/L V on substation network of position. Curving the display is achieved by increasing the pitch of the horizontal members of the alumim'um grid ~ to allow for any internal curvature shrinkage. The curvature can be manufactured to a minimum radius of 4 m. When the customer has established the display requirements, the company can, even from the simplest of thumb-nail sketches, produce drawings and supply anything from a basic passive mimic to a fully integrated system comprising electrical wiring, components
and instruments. Colours can suit British Standard specifications or can be mixed for a specific customer requiremerit. The rigidity of the system, means there is no requirement for a metal frame around the display. Instead, special tiles are available with chamfered edges which can be dropped into the cut-out leaving a finished panel.
