142 Liquid crystal compositions US334107 1994-11-04 US5523013A 1996-06-04 Patrick J. Durbut; Myriam M. Mondin; Guy J. Broze
A liquid detergent composition which is in liquid crystal form comprises a synthetic organic surface active agent, as the detergent component, which preferably includes one or more nonionic detergents of the ethoxylated higher fatty alcohol type, and a lesser proportion of anionic or cationic surfactant, such as sodium dialkyl sulfosuccinate or dicoco dimethyl ammonium chloride, a cosurfactant, such as tripropylene glycol butyl ether, a solvent for the soil, such as an isoparaffin of 9 to 11 carbon atoms or methyl cocoate (ester of methyl alcohol and coco acids) and water, with the water usually being the major component. Such compositions are useful for cold or room temperature cleaning of lipophilic soils, such as animal fats, from hard surfaces and from fabrics, and may be used as pre-treatments to loosen such soils from substrates to facilitate easier cleaning of dishes and laundry with conventional or the invented detergent compositions.The invention also relates to concentrated versions of the compositions, which are not in liquid crystal state but which upon dilution with water are converted to such state. Also within the invention are processes for pre-treating and cleaning materials soiled with lipophilic soils, using the invented liquid crystal detergent compositions. Additional processes of the invention are those in which liquid crystal detergent compositions are made by diluting concentrated compositions with water, and those in which lipophilic materials convert liquid crystal detergent compositions to microemulsion form, which latter processes occur during pre-spotting and cleaning applications when the liquid crystal detergent composition contacts the oily soil on surfaces being treated.

145 Aligned cholesteric liquid crystal inks US798881 1991-11-27 US5364557A 1994-11-15 Sades M. Faris
In color printing, and in the fine arts, cholesteric liquid crystal (CLC) color inks are known to possess much higher color saturation and brightness than conventional pigment and dyed based inks. However, prior art CLC ink formulations are inconvenient because in the liquid phase they have to be confined in cells, and in the solid phase, they have to be applied at high temperature, and have to be aligned by some means to produce the optimum color. This invention solves the problem encountered in the CLC prior art, by making pre-aligned CLC platelets or flakes of appropriate thickness and size and mixing them in appropriate host fluids producing a novel CLC ink which can be applied at room temperature and without the need for alignment. The new pre-aligned room temperature CLC ink can be used as a substitute for conventional inks in almost all printing and plotting, and manual drawing and painting. Using the notch filter CLC platelets, the brightness is further enhanced. This invention teaches the CLC ink concepts, its applications and method of manufacturing.
