Abstract: A bare optical fiber is located within the interstice of three cylindrical pins with the fiber end extending outwardly of the contact assembly. The contact is located within an axial opening of a rotatable drum member with the bare optical fiber end extending outwardly. The drum member is interconnected via bearings to an outer rotatable portion of the drum member. A pretensioning clamp is arranged to receive the bare end of the fiber to secure it between clamp heads which applies an axial tension to the bare fiber with respect to the contact. A cutter blade mounted on the rotatable portion of the drum is adjustable to move a knife edge angularly toward the bear fiber to contact the bare fiber at a point closely adjacent the contact pin ends. Rotation of the outer portion of the drum member scores the fiber, as desired.

Abstract: After removing a portion of the insulative covering from a cable leaving exposed the bare shield, a circumferential cut is made in the shield. A flanged, split-ring cylindrical metal contact is located underneath the braid with the flange extending through the cut. Shrink tape applied over the exposed shield serves to hold this shield and portions of the underlying contact together. A receiver tube located on the cable has an internal shoulder which fits against the contact flange and a gland nut threaded into the open end of the receiver tube has an internal end pressing against the contact flange to force it into contact with the receiver tube internal shoulder.

Abstract: An improved hairpiece foundation means, characterized by a sheetlike fibrous woven fabric base having spaces between adjacent fibers; and a further fibrous sheetlike woven fabric member having air spaces between adjacent fibers sonically welded to the base along a plurality of mutually spaced lines. The hairpiece of the invention provides a continuous breathing relationship for the head of the wearer of the hairpiece as well as reducing the contact of adhesive used to secure the hairpiece to the head of the user with the hairs composing the hairpiece and thereby obviating a source of damage to the hairpiece.

Abstract: A coupling ring is slideably received onto a cylindrical plug shell that is mateable with a receptacle. A removable end piece in the coupling ring end has an internal set of key ways which correspond to a complementary set of keys on the receptacle. The end piece has shallow recesses on its outer surface which align with passageways extending through the coupling ring. Each passageway has a metal ball of such diameter as to have parts thereof extending inwardly of the opening and into the end piece recesses. A locking ring is slidingly received over the outer end of the coupling ring and includes a first portion which contactingly engages each of the metal balls holding them in an inwardly extending relation into the recesses on the outer surface of the releasable portion (locked mode). The locking ring is movable to a second position in which an inner groove is aligned with each of the passageways extending through the coupling ring so as to release pressure on the metal balls (released mode).

Abstract: In a plug and receptacle connector, directly couple to the threads of the coupling ring with threads on the driven portion of the connector (e.g., plug), without a coupling nut, and insert a spring intermediate at least one of the threads on the coupling ring and the driven portion. A split-wave spring having corrugated legs may be used. Another feature is to provide notches on the thread facing the wave spring legs to receive the end of the respective leg for preventing the spring from slipping out of the threads.

Abstract: The cable shield is removed for a short distance from the end cable wire to be inserted into a contact. A generally circular plate has a flange permitting receipt within the connector part shell and a circumferential spring for insuring continuous electrical contact. A plurality of openings are formed in the plate which align with the individual openings in the connector insert. Each plate opening includes a hollow cylindrical metal tube affixed therein with an internal bore enabling receipt of a cable wire with shield and cladding. A leaf spring contact electrode is secured to the wire shield spaced from the cable wire end and lies within the hollow tube, the prepared end of the wire passing out the other end of the tube for receipt within a contact. The plate with tubes is then fitted within the connector part shell providing termination.

Abstract: A spring mechanism is positioned to hold two members of, e.g., an electrical connector which are moveable relative to each other, securely together and to resist motion of the one element with respect to the other in a decoupling direction until the force exerted on the spring exceeds a predetermined force. At this point, the spring, due to its structure, pops or flips to another position producing a decrease in the overall spring diameter causing the spring to clear retaining grooves in one or both of the two members such that the two members are released.

Abstract: Apparatus and method for dithering ring laser angular rotation sensors, including a plurality of such sensors with substantially identical natural dither frequencies and having different sensor axes mounted upon a resilient structure; applying energy to dither such sensors; the energy being connected and disconnected from the dithering of each sensor in response to the amplitude of dither of that particular sensor to minimize lock-in; and frequency or phase modulating the energy applied to dithering to avoid continued uni-directional coning effects.

Abstract: An expandable ring is expanded during connector mating to extend outwardly of the external surface of a connector element which on touching reveals at a subsequent point in time that the connector is mated.

Abstract: Tubular members to be interconnected in a rigid configuration each include a radially extending stud affixed to the tube outer surface (e.g., welded) and terminating in an enlarged head. First and second connector parts each have a relatively flat side which abut against one another in assembly to form an elongated connector, the cross-section of which is circular and of a diameter substantially identical to that of the tubular members. The flat surface of each of the connector parts includes cavities for receipt onto the studs. Each connector part cavity encompasses approximately one-half of the studs such that when the connector halves are fitted onto a pair of studs, they will completely enclose the two studs with the end surfaces of the connector parts contacting the tubular members sidewalls immediately adjacent the studs. The connector parts ends are formed into curved areas such that when they are assembled onto the studs they will smoothly and continuously contact the tubular member surfaces.

Abstract: A pan-type liquid distribution assembly or fractionator which regulates the liquid flow through distribution tubes and, at the same time, provides for clearing away of unwanted fouling material which, in the past, has served to detract from the operation by plugging or partially plugging the liquid pour-points. Adjustment of the flow through, and/or, the unfouling of, the liquid pour-tubes can be performed from a point external of the fractionator, so as not to interfere with the ongoing operation of the fractionation column. A further feature is the ability to adjust liquid flow through each individual tube to alter the distribution pattern of the liquid across the top of a packed fractionation bed.

Abstract: A driver for oblong material having three arms carrying the driving elements which swing vertically with respect to the material path of movement. For a selected setting angle of the arms, the point of contact of a driving roller with the material is displaced such that, on the diameter of the test material becoming smaller, the point of contact is moved towards the edge of the roller. This feature has three desirable consequences: First, wear is not concentrated on a single track of the roller surface; second, the pressing-on force of the rollers is decreased with the decreasing diameter of the test material; and third, when using three rollers, the seeing angle can be adjusted such that for the narrowest approach of the rollers possible, one edge each of a roller meets with the respective edges of the other rollers in one point.

Abstract: Method and apparatus for scanning an object with a probe in which scanning lines for the forward and backward motions run parallel to each other and their mutual spacing from each other remains constant. In one form, the object transportation speed Vt is set relative to the speed Va of the forward and backward motions in such a way that Vt/Va=tangent .alpha.=constant where .alpha. is of the angle between the line of reciprocating movement and a normal to the transportation direction. According to another feature, the angle may be controlled by Vt such that parallelism of the scanning lines is maintained.

Abstract: A flexible bag-like enclosure is carried by a movable arm so that it may be suitably located at any desired position and selectively raised and lowered as desired. A fitting is coupled to the opening of the bag-like enclosure and connected by a length of flexible hose to a source of low-pressure fluid under the control of a selectively actuable valve. The bag-like enclosure includes a substantial quantity of relatively dense, particulate material. A lower surface of the bag-like enclosure has a plurality of openings of a size substantially less than that of the individual particulate members so that they will be retained within the enclosure.The bag-like enclosure is rested on an object to be moved such that the enclosure lower wall will conform to the surface of the object.

Abstract: A lower edge wall of a luggage case part has camming teeth with intervening grooves. The other case part has a set of spaced apart teeth for consecutive meshing with those of the first case part. One or more leaf springs are received across the meshed teeth of the case parts. The dimensions and geometry of the spring are such that when the case parts reach a predetermined maximum opening angle, the central spring portions contact opposing portions of the two case parts forming a limit stop to further opening of the case.
