Title: Image display system using a thin-film actuated mirror array
Inventor: KIM YOU KWANG
IPC: H04N5/74
Filed: 1998-12-22
Abstract: In an image display system capable of displaying an M x N number of pixels based on optical projection, a light source (100) emits a white light, the white light being reflected on a total mirror (106) at a predetermined angle.  An optical filter (108, 110) splits the white light reflected from the total mirror (106) into a trinity of primary light beams, i.e., a red, green and blue light beam. Each of a trinity of arrays of M x N actuated mirrors (118, 120, 122) generates an optical pixel signal by reflecting the primary light beams impinging thereon, each of the actuated mirrors in the arrays (118, 120, 122) being capable of changing the optical path of the primary light beams reflected therefrom, wherein a driver circuit (130) controls each actuated mirror based on an input image signal. A projection stopper (124) partially transmits the optical pixel signal and a projection screen (128) displays the optical pixel signals passing through the projection stopper (124).
Patent CA-2321843-A1 (CA)
Title: Free-flowing basic castable and castings produced therefrom
Inventor: BUGAJSKI JERZY
IPC: C04B35/66
Filed: 1999-03-01
Abstract: The invention relates to free-flowing castable and castings produced therefrom. Refractory nonbasic and basic castables have been known for a long time. The traditional refractory castables have thixotropic properties and must be lined using vibration technology. In the past, free-flowing castables were solely based on alumina raw materials. Attempts to produce an aqueous, highly concentrated basic suspension which would form the basis of free-flowing castables failed to meet the requirements in terms of rheological properties and a low degree of hydration of the MgO-based materials. It is the aim of the invention to provide the above-mentioned castable for the monolithic lining or repair of high-temperature equipment and for the production of refractory castings. This is achieved by providing a fine-grained and a mixed fine and coarse-grained alternative. For the fine-grained alternative a refractory, dilatancy-promoting material on MgO  basis with a grain size between 0.1 and 45 µm and at least one dilatancy-promoting dispersing and wetting agent is employed with the addition of predetermined amounts of mixing water. For the mixed fine and coarse-grained alternative, again on MgO basis, in addition a refractory material with a grain size of up to 15 mm as well as binding agents are employed. In both alternatives, refractory and other additives improving the quality of the final products can also be employed.
