Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure is a high fidelity sound-producing system that has two substantially similar full range drivers capable of accepting energy and producing sound with tolerable distortion over the entire frequency range and one low range driver of appreciably more sound radiating area than the two full range drivers.  The low range drive and the full range drivers are in one enclosure and connected across the amplifier output.          The low range driver resonates at a similar frequency to the full range drivers and the efficiencies of said drivers are matched to provide substantially uniform sound level output over the frequency range of interest.

Abstract: ABSTRACT                     Title "Improvements in or relating to graded index optical fibers"            Graded index optical fibres can be made by a double crucible technique in which the refractive index gradation is induced by thermal diffusion.  In fibre made from alkali-boro-alkaline earth-silica glasses, the refractive index variation in the fibre is improved if the core and cladding glass compositions are selected so that no simple ion-exchange processes occur.  These fibres have improved bandwidth.          Preferred glass compositions for the core contain 55-65 mole per cent silica, 10-20 mole per cent boric oxide, 14-25 mole per cent sodium oxide, and up to 20 mole per cent of alkaline earth oxide, preferred glass compositions for the cladding contain 55-65 mole per cent silica, 10-20 mole per cent boric oxide, 19-25 mole per cent sodium oxide, and the cladding glass contains the same amount or less sodium oxide than the core.

Abstract: APPARATUS FOR REMOVING FOREIGN MATTERS          Abstract of the Disclosure The invention relates to apparatus for removing foreign matter from a liquid.  The apparaus comprises a cylindrical housing, a radial inlet pipe provided on the upper portion of the housing, an outlet pipe axially mounted on the housing at the upper portion, a conical cylindrical filter disposed in the housing and connected to the end of the outlet pipe so as to discharge the liquid from the inlet pipe through the filter and the outlet pipe, a deflector for deflecting the liquid from the inlet pipe so as to cause it to swirl around the filter, and an extracting pipe provided on the housing at the bottom portion.  The filter extends conically from the inlet pipe or outlet pipe toward the bottom of the casing.  The liquid from the inlet pipe is swirled by the operation of the deflector and directed downward by the position of the filter while swirling.  The foreign matter in the liquid and deposited on the filter is swirled by the swirling liquid, and deposited by centrifugal force and downward movement.  The deposited foreign matter is extracted through the extracting pipe by opening it.  The apparatus allows filtering of the liquid stream with very little pressure loss and without undue clogging of the filter.

Title: Tangent function generator for am stereo

Filed: 1980-08-01
Granted: 1983-04-05
Abstract: Abstract A function generator as for use in a system of com-patible quadrature AM stereo approximates the tangent function curve, allowing for the provision of essentially undistorted intelligence signals.  A form of differential amplifier, including additional multiple threshold transistor circuits with common collectors and common bases, has at its input terminals a signal related to an angle of modulation and provides an output signal approach-ing a signal related to the tangent of the angle of modulation, the accuracy of the approximation depending on the number of circuits included.  The function generator has the capability of providing other similar functions and of use in other applications.  As used for AM stereo decoding, a tangent function output is derived from the phase modulation components of the stereo signal and, when multiplied by the amplitude modulated signal, the stereo difference signal can be derived.

Abstract: ABRIDGEMENT          An improved process for preparing a silver catalyst which comprises impregnating a porous alumina support with a silver salt, preferably silver nitrate, by contacting a quantity of the support with an aqueous solu-tion of the salt in sufficient amount to be completely absorbed by said support while under a vacuum.  A dispers-ing agent is also employed in the aqueous silver salt solution.  The support is dried by heating, e.g., 100°C, under vacuum and then, while still under vacuum, impreg-nated with a reducing agent employing an amount suffi-cient to be completely absorbed by the support.  Subse-quent heating at a higher temperature, e.g., 250°C, reduces the silver salt to silver metal.  A catalyst is produced which, when employed for the oxidation of ethyl-ene, permits the process to run 5°C-10°C cooler at the normal conversion, and also gives an improved yield.   27,422-F                -12-

Abstract: TAPE READER MOTOR MOUNT     Abstract of the Disclosure An alignment mechanism for a paper tape reader in which the motor and drive sprocket assembly is firmly, but not rigidly, affixed to a base plate of the main reader unit by a plurality of compressive spring fasteners.  Arcuate slots in a motor mounting base plate, in conjunction with spring-biased retainers projecting through those slots and secured to bosses on a reader base plate, maintain the two base plates in spaced parallel relation and permit limited angular rotation of the motor and drive sprocket assembly, thus facilitating angular adjustment of the motor.  A bias spring applies a torsional force to the motor assembly, forcing it against an adjustable screw stop.  Adjustment of this screw results in rapid and precise single-step alignment without the often disruptive further step of tightening retention fasteners.

Voltages dependent upon the transmitted signal current which are equal in value but opposed in phase appear across the first and second resistors and in addition a voltage which is dependent upon the received signal current appears across the second resistor; in the outgoing direction the four-wire line is subject to a voltage intermed-iate value which is independent of the transmitted signal.  Instead of a four-wire line, separate go and return channels of any form may be utilized.
