摘要： A telephone line circuit and system for interfacing digital exchange line circuits to a terminal interface of a switching network is disclosed. The system includes controllable active circuit impedance matching means for reducing impedance mismatch between a selected line circuit and the terminal interface. Control means controls both the active circuit impedance matching means for adjusting the effective circuit impedance to a value within a predetermined range, and the conditioning circuit gain pads for selectably adjusting the gain of a transmitted signal. Additionally, control means controls the d.c. line impedance and voltage for adjusting the effective line feed current to the subscriber loop, and provides interfaces for a plurality of line circuits to both a switching network and external processor. Supervision means provides supervision control signals to the control means and thereby permits the telephone line circuit system to provide desired telephone system functions.

摘要： A releasable locking mechanism is provided for a rectangular connector in which matching grooves are formed in the outer and inner surfaces respectively of the elongated sides of the shells of the plug and receptacle halves of the connector. Elongated wires are positioned in each of the plug shell grooves. Actuating devices are located at opposite ends of the plug shell which act against inwardly extending legs on the ends of the wires for shifting the wires outwardly to become partially lodged in the grooves in the receptacle shell thereby positively locking the connector members together. The actuating devices may be retracted to allow unmating of the connector halves.

摘要： A tubular formation of particulate optical material is formed by a layer slurry deposition process which involves spraying layer after layer of slurry containing particles of the optical material onto a rotating rod-shaped bait. The composition of the slurry and particularly the index of refraction of the optical material may be varied from one layer to another or from one group of layers to another to obtain a graded or stepped refraction index profile in the formation, in an optical preform formed therefrom, and ultimately in the fiber drawn from the optical preform. The particles of the slurry are suspended in a liquid vehicle which evaporates in the spray stream or shortly after deposition, and are coated with an organic binder which holds them together in the layer and in the formation, so that the formation is self-supporting. Then, the organic binder is removed and the formation is sintered, followed by a collapse of the sintered tubular formation into the optical preform in the form of a solid rod. Then, optical fiber of the desired optical properties can be drawn from the optical preform. The associated apparatus includes a spray gun aimed at the bait rod, and a receptacle for the slurry from which the slurry is supplied to the spray gun. The bait rod is clamped in chucks and is rotated, while the spray gun moves in the axial direction of the bait rod in a plurality of passes to deposit the formation on the bait rod.

摘要： In order to provide a high power heat source having a very clean and invariable heat flux, a ring plasma is induced in a heating zone of a plasma torch including a plurality of coaxial tubular elements and the optical fiber is drawn through a channel passing axially through the center of the plasma torch and of the ring-shaped plasma. In this manner the preform from which the fiber is drawn can be placed in close proximity to the induced plasma without exposure to non-symmetrical temperature variations. Cooling gas passes through the heating zone either in an annular stream surrounding the plasma or in an annular stream passing through the center of the plasma around the preform and the fiber being drawn, or both. The heating zone is protected from environmental disturbances by an extension of the outer tubular element of the plasma torch which surrounds the heating zone. The plasma is induced by an RF source in an undisturbed stream of a plasma-forming gaseous medium, such as argon or a mixture of argon with oxygen, which flows through the heating zone.

摘要： A triangulated rib structure including first, second and third sets of "egg-crate" interlocking ribs. The first set is oriented in a predetermined direction such as the horizontal or vertical coordinate, and the second and third sets are oriented at angles of first and second senses, respectively, thereby forming triangulated spaces which are inherently rigid. The individual ribs have edges falling adjacent to a desired overall reflector surface, each of these being precut before assembly to provide the required line of curvature as a function of the individual ribs placement. Each rib is itself a planar piece, and the "egg-crate" interlocking slot joints may be stabilized with one or more seam welds. A conductive mesh forming the actual contoured reflector surface is conformed to the desired contoured shape and affixed as by tack-welding to the edges of the ribs adjacent the contoured surface.
