    摘要： A method is provided for measuring the onset of polymer solidification, i phase transitions from liquid to crystal or liquid to glass, during injection molding to detect characteristic fluorescence radiation from a dye which has been doped into the polymer at very low concentration. The method involves the use of a calibration relationship between the fluorescence intensity and temperature of the doped polymer in order to determine distinct features which characterize the onset of solidification.

    摘要： A method and apparatus for monitoring the crystallinity and shrinkage of aolymeric resin during molding in which light is introduced into the mold cavity, from an optical fiber through a light permeable window, transmitted through the resin in the mold, reflected from the opposite side of the mold, collected again by the optical fiber sensor, and the attenuation of the light is analyzed to detect mold filling, the onset of polymer crystallization, and separation of the polymeric material from the mold wall due to shrinkage, which separation also produces the geometry of an interferometer which can be used to detect shrinkage and to measure the rate of shrinkage by counting the minima of interference fringes.

    摘要： Photoconductive zinc oxide characterized by having improved electrophotographic properties and particularly increased discharge speed, and produced by a process involving mixing the photoconductive zinc oxide powder to be improved with 0.01% by weight or more tellurium calculated as Te, and contacting the thus-obtained mixture with a free oxygen-containing gas while heating the mixture at elevated temperature sufficiently high and for a time sufficient to result in the zinc oxide having the improved electrophotographic properties. The heating temperature and/or heating time is held below that temperature or time at which sintering of the thus-treated product occurs.

    摘要： A fire protection system for determining the existence of hazardous conditions within a building. The system includes a central monitor node for monitoring and displaying system status information. At least one zone node is located remote from the monitor node, and defines a plurality of fire protection zones within the building. A plurality of detectors are arranged within each zone at respective predetermined address locations. Each of the detectors includes a microcontroller for detecting and storing information indicating an occurrence of a hazardous event. The detectors have a normal negative state wherein no occurrence of a hazardous event is detected, and a positive state wherein the occurrence of a hazardous event is detected. The zone node includes detector interrogation circuitry for interrogating the plurality of detectors to determine their respective positive or negative states, and for determining the address location for each of the plurality of detectors in a positive state indicating the occurrence of a hazardous event. A communication line electronically interconnects the zone node and the monitor node for relaying information from the zone node to the monitor node indicating the address location for each of the plurality of detectors in a positive state. The address location of all detectors in a positive state is displayed to a system user at the monitor node.

    摘要： A coaxial adjustable hydraulic clutch actuator of the invention for use with an automotive transmission and clutch, as in a racing vehicle for coupling power from the engine to the transmission. The transmission has a power input shaft and the clutch has actuating elements, the engine and transmission being joined by a bell housing. The actuator includes a base housing configured for retaining a bearing of the input shaft. A sleeve extends forwardly from the base housing coaxial with the input shaft. A piston is fitted coaxially within the sleeve and is received within an annular hydraulic fluid chamber to which hydraulic fluid is supplied under pressure from exteriorly of the bell housing. A clutch throw-out bearing is carried coaxially by the piston for being driven into throw-out engagement with the actuating elements of the clutch by movement of the piston in response to the hydraulic fluid pressure for clutch actuating operation. The piston is resiliently urged toward the base housing by a sleeve and spring assembly for normally maintaining the actuating bearing in a disengaged position. The base housing includes provision for adjusting the axial position of the throw-out bearing in precise disengaged position relative to the clutch actuating elements.
