Abstract: A B S T R A C T          The apparatus comprises: firstly a support (4) having at least one surface (40) which is made of soft, elastically deformable material and which includes a groove (5) suitable for receiving the ends of two optical fibers (1, 2) to be connected in end-to-end contact; and secondly a member (8) which is kept bearing against the support surface and the ends of the optical fibers. Said member (8) comprises a polished rigid part such that keeping it bearing against the support surface (40) exerts a compression action on the said ends of the fibers, giving rise to radial reaction from the wall of the groove against the ends of the fibers, and thus ensuring that the fibers are aligned.

Abstract: METHOD AND APPARATUS FOR HEAT SETTING FASTNER ELEMENTS          Abstract:     A method of heat setting spaced fastener elements on a fastener chain includes contracting a formed thermoplastic wire constituting the fastener elements, while heating the fastener chain to which the formed wire is affixed, until the pitch of the fastener elements attains a predetermined value smaller than the value of a desired pitch and sub-sequently cooling the formed wire while the wire is stretch-ed to provide the desired  element spacing.  Apparatus for practicing the method includes a rotated heating wheel having circumferential teeth the pitch whereof is less than the desired element pitch in order to engage and contract the formed thermoplastic wire while the fastener chain bearing the wire is heated, a rotated cooling wheel having circumferential teeth the pitch whereof is equal to the desired element pitch in order to engage and stretch the molded wire while the fastener chain, received from the heating wheel, is cooled, and means for heating the fastener chain as the chain traverses the outer periphery of the heating wheel.

Abstract: ABSTRACT     A precision alignment apparatus for precisely orienting and stabilizing the orientation of a sensor, for example a magnetometer sensor, is disclosed.  The simplest embodiment of the invention consists of a sensor support and a second support on which the sensor support is mounted with a trunnion.  A wedge engages the two supports on one side of the trunnion axis so that advancement of the wedge will rotate the two supports relative to one another.  A lead screw connected to the wedge serves to advance and retract the wedge relative to the supports.  Rotation of the two supports is opposed by a stabilization mechanism that can be another wedge and lead screw assembly or a spring.  In more complex embodiments an additional support and an additional wedge mechansim are employed for orienting the sensor about another axis.  Three axis adjustment is likewise possible.

Abstract: RCA 82,624 A b s t r a c t An improved color picture tube has an inline electron gun for generating and directing three inline electron beams, comprising a center beam and two outer beams, along initially coplanar paths toward a screen of the tube.  The beams pass through a deflection zone adapted to have two orthogonal magnetic deflection fields established therein.  A first of the fields causes deflection of the beams in a first direction perpendicular to the inline direction of the beams, and a second of the fields causes deflection in a second direction parallel to the inline direction of the beams.  The gun includes two shunts for shunting portions of both deflection fields around the outer beam paths. Each shunt comprises one magnetically permeable member having an aperture therein and completely surrounds one of the electron beam paths. The improvement comprises each shunt being longer in the first direction than in the second direction, and being symmetric about a central axis of the shunt that parallels the first direction and symmetric about another central axis of the shunt that parallels the second direction.
