Abstract: An optical fiber package (52) includes a length of optical fiber (22) wound in a plurality of convolutions on a bobbin (50). In order to maintain the convolutions in a precision wound package and to prevent snags during payout, it is necessary that each convolution of optical fiber be adhered to at least a portion of an adjacent convolution. This is accomplished by providing the length of optical fiber with an adhesive material (32) which is not tacky at room temperature but which becomes tacky at a predetermined temperature. After the convolutions have been wound on the bobbin, the bobbin is treated to cause the adhesive material to become tacky and cause each convolution to adhere to at least a portion of adjacent convolutions. Suitable adhesion is caused to occur with any adhesive material for which molecular bonding can occur across the interface between contiguous portions of adjacent convolutions as a result of suitable treatment. The adhesion between convolutions is sufficient to cause a precision wound package to be maintained, but is such as to allow separation of each convolution from an adjacent convolution during payout without the occurence of breaks.

Abstract: Dual parison extrusion head (10) for multi-layer extrusion blow molding in which a die body surrounds two parallel spaced mandrels to form two cylindrical passages (12, 14) from which parisons are extruded. A series of resin supply conduits are provided for directing each resin to both passages. The series of conduits are axially spaced in the extrusion head to direct a plurality of plastic resins to each of the passages to form a multi-layer parison. The resin supply conduits (20, 22) are symmetrical about a vertical plane transversely bisecting the extrusion head between the two passages to produce flow and thermal symmetry in the resin to balance the resin flow to both passages. The resin supply conduits are configured so as to produce the dual parisons with the resin weld line of the multiple resin layers being located on the blow mold parting line. The resin conduits are positioned to minimize the center distance between parisons to reduce the size of the extrusion head. This is accomplished in part by feeding the resin downwardly before the resin flows into the cylindrical passages to form the parisons.

Abstract: Remote disconnection devices are needed for being able to determine at the interface between the telephone network of one operator and the network of another operator the part of the coupled networks in which a fault has occurred, that is to say to separate the networks from one another with respect to direct voltage for measuring purposes. Remote disconnection devices based on TRIACs and MOSFETs are known where a uniform switching threshold is used. If controlled silicon rectifiers are used as electronic switches, the switches are connected to one another by a switching element in order to be able to transmit dialling pulses from the telephone to the exchange and to use switches with tolerant control connections. According to the invention, the use of self-inhibiting MOSFETs of the enrichment type provides for a high turn-on threshold and a low turn-off threshold so that the usual measuring method of lowering voltage can be used. It is also possible to make the turn-on threshold dependent on the polarity of the voltage. <IMAGE>
