Liquid or Solid Display System

A liquid or solid display is constructed from plastic or glass tubes placed next to each other forming a display similar to a standard television raster. The input is supplied from a rotating distributor or put contains a return box, color separator and pump.

The information can be fed to the display in a serial manner similar to a standard TV system. The device includes a plurality of parallel transparent tubes mounted horizontally. Each tube is filled in sequence with dark and light material, i.e., liquid, by the distributor, which can consist of a group of hydraulic valves. When the display is complete, it can be retained in the tubes for any desired time.

When a new display is desired, the liquid in the tubes is channeled into the return box and it is then pumped into the color separator. The dark and light liquid can be of different densities such as oil and water and the color separator is a device to allow the oil to rise to the top of the water. The two liquids are then selectively pumped to the distributor by the dark color control and the light color control, each of which can include a pump and a controlled valve.

Instead of using liquids, a solid display can be constructed using magnetic and nonmagnetic or size differential separation. A preferred system uses solid balls and air pressure. The solid balls give better registration in the display and easy color separation. These can consist of three or four different colors...
