摘要： A composite material having droplets of a liquid crystal material in a matrix of a coploymer of a multifunctional acrylate, or a mixture of different multifunctional acrylates, and a multifunctional mercaptan is prepared by photopolymerization. The liquid crystal material is initially mixed with a multifunctional acrylate monomer, a multifunctional mercaptan, and a photoinitiator to form a solution. The solution is exposed to ultraviolet light, whereupon the multifunctional acrylate monomer and multifunctional mercaptan copolymerize in a step reaction, and the liquid crystal separates from the copolymer as droplets dispersed throughout the copolymer matrix. The resulting material is placed between transparent, electrically conducting plates to form an electro-optic display device.

摘要： A composite material includes droplets of a liquid crystal material dispersed within a matrix of a photopolymerized polymer. The material is prepared by forming a solution of the liquid crystal material and a monomer, and then polymerizing the monomer with light. The solubility of the liquid crystal material in the polymer is less than in the monomer. As polymerization progresses, a portion of the liquid crystal material separates as a second phase in the polymer matrix. The liquid crystal can be any suitable such material that is soluble in the monomer and less so in the polymer, and the monomer is a polymerizable acrylate or methacrylate. Liquid crystal devices are prepared by forming the composite material between two electrically conducting substrates.

The sensor comprises (a) a dielectric substrate having a major surface; (b) a pair of electrically conductive electrodes disposed on the major surface of the substrate; and (c) a conductive polymer covering the pair of electrically conductive electrodes, with the conductive polymer doped with appropriate dopants in measurable excess of that stoichiometrically required to change the conductive polymer from a neutral state to a charged state to provide requisite conductivity. A method for making the sensor is provided, as is a method of use of the sensor which relates to its use in a monitoring system comprising a means for measuring the conductivity of the sensor connected to a warning means for providing an indication when the conductivity reaches a predetermined level. Contemplated specific methods of use include the detection of fugitive emissions in chemical plant environments; the detection of certain pollutants in vehicle exhaust; and the detection of certain pollutants near chemical handling operations, such as painting operations.

摘要： A sensor for monitoring the water content and the acid content in the presence of water in nonaqueous media can be incorporated into a monitoring system for monitoring the quality of nonaqueous fluids in equipment or vehicles. The sensor comprises an insulating substrate; electrodes formed on the substrate in an interdigitated pattern; and a conductive polymer deposited over the interdigitated electrodes which bridges between adjacent digits of the electrodes. The monitoring system incorporating the sensor comprises a control module for measuring the conductivity of the sensor. The control module is preprogrammed to compare the measured conductivity to a predetermined level indicative of an unacceptable level of degradation. The sensor is made by depositing electrodes on an insulating substrate; depositing a conductive polymer over the electrodes in an amount sufficient to bridge between the electrodes; and neutralizing the conductive polymer to an insulating form. A method of sensing water and acid in the presence of water in nonaqueous media exposes an insulating form of a conductive polymer to a nonaqueous medium and monitors the conductivity of said conductive polymer, as the nonaqueous medium is used. The conductive polymer reversibly increases conductivity in measurable amounts with increasing acid and/or water content due to protonation by the acid or hydration by the water.

摘要： Apparatus for positioning a golf ball on a tee and for retrieving golf balls and tees. A hand-operated apparatus for setting golf balls on tees without requiring the golfer to bend is described. The device may also be used for retrieving golf balls and tees, and may itself be retrieved if dropped by using the handle of a golf club. The apparatus comprises a hollow outer shaft having a fixed handle at one end and a base for pivotably holding two golf ball encircling jaws at the other. An inner shaft, slidably disposed within the outer shaft and connected to a movable handle at one end, and jaw-actuating wires at the other permits a user to operate the jaws with one hand. A coil spring located between the fixed and movable handles provides a force therebetween, keeping the jaws closed in their normal position. A golf ball and tee placed within the jaws may be set in the ground by pushing on the fixed handle, and released from the apparatus, such that the golf ball remains on the tee, by pulling the movable handle against the operation of the spring.

摘要： New nematic liquid crystal (LC) ester mixtures with relatively short average molecular lengths are made by including one or more binary sets of components which have identical, or nearly identical, molecular lengths. Undesirable solids solution phase effects are avoided by either utilizing appreciable asymmetry in the alkyl end groups or by combining LC esters of different classes.

摘要： We have disclosed a new class of thermosetting copolymers derived from terephthalonitrile N,N'-dioxide and polyimide oligomer that cure through addition reactions to form essentially void-free cured resins that exhibit outstanding high temperature stability. These copolymers may be formed from either acetylene terminated polyimide oligomers or nitrile terminated polyimide oligomers. Copolymers prepared in accordance with our invention exhibit little or no outgassing during cure and are extremely useful in the preparation of laminates where high temperature stability and high strength is required.
