Abstract: A totally dielectric cable includes a core comprising a plurality of optical fiber transmission media. The core is enclosed by a core tube which is made of a plastic material and water blocking provisions are provided within thecore tube for preventing the longitudinal migration of water. A water blocking tape may be provided in engagement with an outer surface of the core tube and a plastic jacket is extruded thereover. Interposed between the outer surface of the jacket and the core tube are two diametrically opposed pluralities of strength members each of which may be made of glass fibers. At least one strength member of each plurality is rod-like to provide compressive as well as tensile strength for the cable. The remaining strength members of each plurality are relatively flexible rovings which supplement the tensile strength of the rod-like members. The strength members are disposed and have a stiffness modulus which are effective to minimize any tensile strain which is imparted to the rovings.

Abstract: A METHOD FOR DELETING A MARKED PORTION      OF A STRUCTURED DOCUMENT           Abstract A method is disclosed for deleting a marked portion of a structured document so as to prevent damaging the structure of the document.  The method examines the contents of a marked portion of a structured document and determines which begin and end tags are unmatched.  A begin tag whose end tag has not been marked or vice versa, is flagged so that it is not deleted when the contents of the mark are deleted.  This allows the Structured Delete function to delete a marked portion of the structured document without damaging the document's structure.

IPC: H02B1/01
Filed: 1990-05-31
Abstract: 00219-673 GWH:jy ABSTRACT            A framework assembly system (particularly intended for the assembly of switchgear cubicle frameworks) comprises vertical and horizontal structural members and corner pieces for the connection  of  the  structural  members.    The  vertical  and horizontal   members   share   an   identical   cross-sectional configuration comprising a square, partial box-section having longitudinal flanges extending along the free edges thereof. The flanges have holes spaced along their lengths.  The corner pieces have three identical, orthogonally oriented faces, also provided with holes whose spacing and diameter is the same as those of the structural members.  The vertical and horizontal members differ only in the distance from the end of their box-sections at which the flanges terminate, which distances are determined by the dimensions of the box-sections and flanges and the spacing of the holes.   The structural members can thus be easily cut to any required length on-site.  The system may be assembled using only a single size of nut and bolt, and comprises only three different components which are easily fabricated from pressed steel.  The system also allows  frameworks  to  abut  one  another  without interference of bolt-heads or the like.
