摘要： In a liquid crystal image display system, a fiber optic faceplate which transmits light only through a well defined acceptance cone is optically coupled to the liquid crystal display surface of a reflective dynamic scattering mode liquid crystal display device.In an image projector embodiment, light from an external light source is directed through the faceplate onto the liquid crystal display surface. Light scattered by activated (on-state) regions of the liquid crystal is substantially absorbed by the faceplate while light reflected from the non-activated (off-state) regions of the display surface is transmitted back through the faceplate to a projection lens which forms an image on a viewing screen.In a second embodiment of the invention, a viewer directly observes the liquid crystal display surface under ambient light from either natural or artificial light sources. By absorbing light from unwanted sources outside its transmission acceptance cone, the faceplate prevents loss of image contrast while transmitting light from sources within its acceptance cone needed to illuminate the display.

摘要： In an electro-optical display device, a fiber optic faceplate which transmits light only through a well-defined solid angle, is optically coupled to an electro-optical display panel having a specularly reflecting surface. The display panel can be either an active device, such as laser diodes, or passive such as a dynamic scattering liquid crystal device. The axes of the optical fibers comprising the faceplate are slanted to the display surface at an angle such that the light which enters the front surface of the faceplate and is specularly reflected from the display surface is trapped within the faceplate. However, light emitted or scattered from on-state display elements is transmitted through the faceplate to the viewer.A high contrast display results because off-state display elements on the display surface appear dark under even intense ambient illumination whereas the on-state elements appear bright.The faceplate has two major opposing surfaces which are aligned to one another at a predetermined angle in order to control the size and direction of the display field of view.

摘要： A sheet feeder transports sheets from a sheet supply, such as a document tray, to a distant location, such as a registration position on the platen of an electrophotographic copier. A sensing device monitors a time period which starts when a sheet advancing mechanism is actuated and ends when a sheet reaches the distant location. An indication of abnormal operation is provided if the sheet does not reach the distant location within a preset time period. The preset time period is initially set at one period of time and subsequently set at a shorter period of time. The initial time period is longer to allow the sheets to become fully engaged with the sheet feeder after initial loading, while the subsequent period is shorter to provide a quicker indication of abnormal operation.

摘要： A method of transalkoxylation of nucleophilic compounds in which an alkoxylated and a nucleophilic compound are combined in a suitable vessel and reacted in the presence of a heterogeneous catalyst under conditions capable of transferring at least one hydroxyalkyl group from the alkoxylated compound to the nucleophilic compound. The method is especially useful in the transalkoxylation of alkanolamines to transfer a hydroxyalkyl group from an alkanolamine having a greater number of hydroxyalkyl groups to an alkanolamine having a lesser number of hydroxyalkyl groups.

摘要： The present invention relates to post-treatment compositions and methods useful for modifying the distribution of metal biocide(s) in biodegradable substrates such as wood, other cellulosic products, starch-based products, and the like that are vulnerable to decay due to insects, fungi, microbes, and the like. The compositions include complexing agents of moderate strength that are able to facilitate mobilization and redistribution of metal biocide(s) in substrates without undue leaching. The compositions can be used, for example, to redistribute the metal biocide(s) into depleted regions of a substrate by redistribution of metal biocide from other regions of the substrate. Post-treatment compositions that include additional metal biocide can also replenish these regions with the freshly supplied, additional biocide. Thus, the depleted regions can be restored by redistribution and/or replenishment mechanisms. Service life of substrates in the field benefits by these post-treatments as a consequence.

摘要： The invention relates to a light-absorbing contact lens and process for preparing same. A contact lens is tinted with colorants which provide desired spectral transmittance characteristics over the tinted portion of the lens. The contact lens provides transmittance of incident radiation having a wavelength from 500 to 700 nm which is variable and wavelength-dependent. The lens of this invention also preferably filters out ultraviolet and blue light (wavelengths from 200 to about 500 nm). Various transmittance patterns for wavelengths from 500 to 700 nm are obtainable by appropriate choice of colorant combinations; the transmittance curve in this region and the colorants to achieve the desired transmittance characteristics are chosen to fill particular needs of a wearer as for example limiting transmittance of visible light in high intensity light environments. Lenses according to the invention may provide unique benefits for use with particular applications such as sporting activities, recreational activities, or the like. Both hard and soft contact lenses are disclosed, and various examples of specialized lenses for particular applications are disclosed.

摘要： Documents are advanced to a registered position along the trailing edge of the exposure platen of an electro-photographic copier by a flat belt supported adjacent to the registration edge by a pulley formed with axially spaced indentations to produce corresponding corrugations in the belt. A registration gate having a blocking position in which transversely spaced fingers extend into the belt corrugations arrests the documents at the registration edge while the normal-diameter portions of the belt pulley press the document downwardly to prevent it from riding over the registration gate. Position pulses from an encoding wheel are counted to determine the position of the document, and drive motor is slowed to one-fifth its normal speed when the document advances within a predetermined distance of the registration edge. After the platen belt is stopped for copying of a first original, a second original is advanced from a stack into a nip formed by the belt and a preregistration roller adjacent the entrance end of the platen. Upon actuation of the belt to feed the preregistered sheet to the platen, the feed elements for advancing the sheets from the stack are momentarily reactuated to ensure separation of the sheet supplied to the preregistration nip from the remaining sheets in the stack. A relatively long prefeed time is allowed for advancing the first original to the preregistration nip to prevent the erroneous declaration of a fault while an initially loaded stack is becoming entrained in the stack feeding elements.

摘要： A solid state dot sequential color display device is disclosed. A color image is formed in a liquid crystal display panel by breaking each picture element up into its three primary color components and presenting them in an adjacent manner. The space occupied by a trio of primary color elements is smaller than the resolving power of the human eye. Techniques of large scale integration (LSI) are employed to effect the required addressing circuitry as applied to a matrix array of triads of reflective electrodes in the dynamic scattering liquid crystal display panel. Arrangements used to form the basic color cells involved are: (a) deposition of band-pass filters in front of the display and (b) deposition of band reflection mirror in back of the liquid crystal material.

摘要： The present invention provides methods that are used to decolorize compositions containing one or more amines in the presence of one or more weak acids. Significantly, the weak acids, particularly organic acids such as glacial acetic acid, when used in combination with a heat treatment produce dramatically less by-products than do the stronger mineral acids, making heat treatments and subsequent separation techniques more effective while producing less waste. In some modes of practice, the weak acids do not need to be neutralized, eliminating neutralizing steps and waste streams associated with neutralization. Low color products can be obtained easily at very high yield as a consequence.
