Electrostatically deflectable light valve with improved diffraction properties

Abstract: An electrostatically deflectable light valve adapted for use in an array for producing television pictures as a projected image upon a large display screen. The light valve structure is such that a plurality of reflective wing portions are free to be deflected along directional axes which are at an angle to the prime directional axes of the overall array, so that light which is predominantly diffracted along the array axes may be decoupled or separated from the signal light produced by activated light valves and used to project the image. The contrast ratio of signal light to background light for the system is significantly improved, using this method of discrimination.

Monolithic glass formation by chemical polymerization

Abstract: Historically, glasses have been formed by solidification of oxide melts from elevated temperatures. Recently it has been demonstrated that monolithic oxide glasses can be formed by chemical polymerization at low temperatures. By the use of this technique, high-temperature reactions such as crystallization, phase separation, etc., which restrict glass formation in certain systems and regions, can be largely avoided. Thus, the technique not only permits investigation of glass structure from a fundamentally different point of view, but also allows the formation of new glasses which can not be formed by thermal means.

Fault Protection with a Digital Computer

Abstract: A fundamental basis has been developed for the use of a time-shared stored-program digital computer to perform many of the electrical power-system protective-relay functions in a substation. Logic operations are given to detect a fault, locate it, and initiate the opening of the appropriate circuit breakers, whether the fault is in the station or on lines radiating from the station.

Static Dielectric Constant of SiC

Abstract: Using the Lyddane-Sachs-Teller relation, published data, and a simple analysis, we find the static dielectric constant of cubic SiC to be ${\ensuremath{\epsilon}}_{\mathrm{s}}=9.72$. The same method yields ${\ensuremath{\epsilon}}_{\mathrm{s}}(\ensuremath{\perp})=9.66$ and ${\ensuremath{\epsilon}}_{s}(\ensuremath{\parallel})=10.03$ for $6H$ SiC.
