Abstract: FULL DUPLEX MODEMS AND SYNCHRONIZING    METHODS AND APPARATUS THEREFOR                     ABSTRACT Full duplex modems and synchronizing methods and apparatus therefor which allow the relatively low cost realization of full duplex modems compati-ble with prior art data sets such as the Bell System 212A Data Set.  The modems utilize relatively little bandpass line filtering with post demodulation filters which provide normal filtering of second harmonic products, but further also serving to make up for the lack of the ordinarily heavy line or predemodulation filtering commonly used to reject the other channel.  In addition, the automatic gain control is provided after the post demodulation filters rather than on the incoming line itself. Carrier sync and timing error corrections are provided under software control, with timing error corrections being achieved by sensing certain phase differences and providing a correction in response thereto.  The use of switched capacitor filters, as well as other techniques herein dis-closed, allows the use of two identical large scale integrated circuits to provide most of the transmit and receive functions of the modem.

Abstract: ABSTRACT         A method for breaking or severing a rod of brittle fiber material, such as glass optical fiber, to produce a mirror end surface thereon, normal to its longitudinal axis and free of imperfection, is described wherein a linear section of the fiber, usually stripped of its outer pro-tective coating or cladding, is supported and held at and between spaced zones and sequentially subjected to grad-ually increasing axial tension while its exterior surface is scored by a rotatable cutter or scoring wheel moving in and along a plane normal to the longitudinal axis of said section to effect its separation or cleavage along said plane.  An adjustment system to accommodate different sizes and types of fiber optic materials is provided for regu-lating the axial tension imposed on said section, the angle of attack and scoring pressure exerted by the cutter wheel, the distance of the plane of severance relative to the mounting zone for an optical fiber connector fitting and the holding or radial gripping force exerted on the fiber.  The sequential steps of tensioning and scribing or scoring the fiber also are selectively reversable.  A man-ually actuatable tool for accomplishing the foregoing steps is also described wherein the program of holding, tension-ing, scoring and cleaving of the fiber is carried out in-dependently of manually applied tool operating force.

Abstract: RUBBER-LAGGED SHEAVE                         Abstract A pulley or sheave that is lagged with rubber or rubber-like material, having two disc-like members which are disposed broadside to each other and secured together to form an annular groove for receiving and guiding a strand of material.  At their centers, the members have bearing means to accommodate a spindle. In the annular groove for the strand of material the members have op-positely disposed wall portions characterized by re-entrant side walls.  A wear strip of relatively soft resilient material, such as rubber, having an elongate rib occupies the annular groove, the rib being accom-modated in and frictionally seized by the re-entrant side walls.  The wear strip has abutted ends, and pre-sents an annular exterior space for engagement with the strand of material that is being handled.  The advantage of the present construction over the devices of the prior art is that low-cost plastic and rubber materials can be employed for the most part, whereby a corrosion-resistant, inexpensive but sturdy and high-quality con-struction is realized.  In addition, assembly is facili-tated, and replacement of the wear strip can be readily accomplished by unskilled personnel, with no special tools being required.
