摘要： Attachment hardware (10) and modular furnace lining (50) which may be secured to an interior surface (not shown) of a furnace by any one of a variety of methods. e.g., welding, self-tapping screw, or to a previously secured stud or matingly configured member. In a preferred embodiment the module is formed of refractory ceramic fiber blanket portions (58) which are retained into a modular unit by the hardware system. Each module includes hardware having support structure which passes through the layers of blanket adjacent the furnace wall. The hardware includes a collar (18) which is moveable relative to the base bar (12) to allow adjustment of the position of the module and means to facilitate access from the hot face (51) of the module to install it.

摘要： Relatively weak light signals are detected by a reverse biased photodetector (10, 30, 50, 70) that is a semiconductor diode including a transparent, electrically conductive front contact (24) formed of a thin film of a transparent, electrically conductive oxide, a body (20) of disordered silicon including three layers (21, 22, 23), the outer layers (21, 22) being oppositely doped and the central layer (23) being substantially intrinsic, and a second, rear contact (13) disposed on silicon body (20) opposite the front contact (24), and monitoring changes in the current flowing through the reverse biased diode relative to the dark current of the diode. In order to achieve desired quantum efficiencies in the spectral region from 200-400 nm, the oxide film is less than 50 nm in thickness and most preferably is about 15 to 30 nm in thickness. The photodetection method is particularly effective at elevated temperatures where its noise is significantly less than that of known photodetectors.

摘要： An extended life capacitor is disclosed in which an enclosing body is made from a tantalum can (12) and tantalum cap (17) and enclosing a plurality of double layer capacitor cells (31). Each of the capacitor cells (31) includes a conductive material, such as activated carbon (34,35), with an aqueous electrolyte therein such as dilute sulfuric acid. In the preferred embodiment, this is about 38% by weight of sulfuric acid, and the remained water. Lead-ins (23,27) are provided to make electronic connection to the two ends of the capacitor cell stack as anode and cathode electrodes. The entire unit is hermetically sealed and the electrodes are at least partly coated with a noble metal such as gold.

摘要： i A ceramic part (12) having either a boss projecting therefrom or a bore (14) therein is joined to a metallic part (24) having a complementary boss (32) or bore. The ceramic and metallic parts (12, 24) overlap one another such that the boss (32) is within the bore (14) when assembled. A metallic insert (18) is bonded to the ceramic part (12) and secured by threads to the metallic part (24) in the overlapping area. - Metallic part and metallic insert are dimensioned such that when the joint is fully assembled an end of the insert bears on the metallic part, and the ceramic and metallic parts do not contact one another. A particular embodiment is a metallic needle valve stem having a readily replaceable ceramic tip.

摘要： Crystalline silicon carbide wherein at least 90 weight percent of the silicon carbide is formed from a plurality of hexagonal crystal lattices wherein at least 80 weight percent of the crystals formed from the lattices contain at least a portion of opposing parallel base faces separated by a distance of from 0.5 to 20 microns. The crystals may be in the form of separate particles, e.g. separate platelets, or may comprise an intergrown structure. The crystalline silicon carbide of the invention is produced by heating a porous alpha silicon carbide precursor composition comprising silicon and carbon in intimate contact to a temperature of from 2100.degree. C. to 2500.degree. C. in a non-reactive atmosphere. The materials are high performance materials finding use in reinforcing, high temperature thermal insulating, improvement of thermal shock resistance, and modification of electrical properties.

摘要： Gas is dispersed into molten metal by immersing a shaft-supported impeller into the molten metal and by pumping gas through the shaft and out of the impeller. The impeller is in the form of a rectangular prism having sharp-edged corners that shear the gaas into finely divided bubbles. The particular shape of the impeller provides an especially effective bubble-shearing and bubble-dispersing action.
