Abstract: A new and distinct cultivar of dwarf Bermuda grass, named RJT, is described and illustrated herein. The cultivar is characterized by its very fine texture when closely mown, the retention of its fine texture at higher heights of cut, its low nutrient needs, its very low thatching characteristics as compared to other dwarf Bermuda grasses, and its prolonged proven stability against mutation.

Abstract: A novel seashore paspalum cultivar (Paspalum vaginatum) is disclosed. The ‘SDX-1’ cultivar is characterized by having a fine texture, greater sod strength, increased rooting, improved color, improved density, and greater salinity tolerance. The cultivar is particularly well suited for golf courses, grass tennis lawns, lawn bowls, lawns, and athletic fields.

Abstract: A window whose light transmission can be mechanically controlled and varied smoothly from a high value of approximately 40% to a low value of approximately 1% is achieved without the requirement of rotation. Polarizing molecules are coated onto four different surfaces in particular patterns. When the coated panels are assembled in the disclosed manner light transmission can be modified with only small translational movements. Durability benefits are also achieved, as well as the potential for lowered heat transmission.

Abstract: This invention relates to a new and improved light-polarizing sheet comprising molecularly oriented polyvinyl alcohol containing an oriented block segments of polyvinylene and said polyvinyl alcohol. In particular, the polarizing sheet comprises a polyvinylalcohol/polyvinylene block copolymer material wherein the polyvinylene blocks thereof are formed by molecular dehydration of a sheet of polyvinylalcohol; said sheet of polyvinylalcohol/polyvinylene block copolymer material comprising a uniform distribution of light-polarizing molecules of polyvinylalcohol/polyvinylene block copolymer material varying in the length, n, of the conjugated repeating vinylene unit of the polyvinylene block of the copolymer throughout the range of from 2 to 24; the concentration of each of said polyvinylene blocks, as determined by the absorption of wavelengths ranging from 200 to 700 nm remaining relatively constant, the degree of orientation of said light-polarizing molecules, as measured by the spectral dichroic ratio, R.sub.

Abstract: A liquid-crystal display system includes a display having a bistable liquid-crystal material, such as a ferroelectric material, and two sets of electrodes disposed substantially perpendicularly to each other and on opposite sides of a layer of the liquid-crystal material. In each set of electrodes, drive circuitry is connected via resistors to front terminals of each of the electrodes, and via resistors to back terminals of each of the electrodes. The drive circuitry provides further that drivers having equal number of output drive ports are coupled via a network of electrical conductors to the front terminals and the back terminals of electrodes in each set of the electrodes in accordance with an arrangement wherein the front terminals are arranged in groups such that, within each group, the front terminals are connected to corresponding ports of a driver.

Abstract: An improved liquid crystal display includes, in sequence from the viewing surface to the medial plane of the display, a substantially transparent polymeric layer, a polarizing layer, a protective layer, a transparent electrode layer, an alignment layer, and a layer of liquid crystal material. The use of a polymeric layer with a polarizing layer intermediate the polymeric layer and the liquid crystal material results in a relatively lower cost display in which the optical anisotropy of the polymeric material does not adversely affect the operation of the liquid crystal display.

Abstract: A novel seashore dropseed (Sporobolus virginicus) cultivar (‘BT-l’) is disclosed. The ‘BT-1’ cultivar is characterized by enhanced turf quality under mown and high traffic stress conditions; improved, darker green leaf color; lower growth habit; denser, more tightly knit sod; low mow height tolerance; finer-textured leaf blades; and increased saline and drought tolerance.
