Abstract: ABSTRACT OF THE DISCLOSURE     An optical fiber distributing and connecting equipment is in the form of a box in which first optical fibers fanned-out from first cables are connected to second optical fibers fanned-out from second cables by means of fiber-to-fiber connectors. In order to achieve easy mixing of the second fibers while ensuring that their lengths remain substantially equal, the connectors are laid out in a circular region. This region includes one or more circular, coaxial and possibly stacked slides, on which the connectors are slidably mounted. Ends of the first fibers are inserted in first ends of the connectors located on the outer edge of the slides , and the ends of the second fibers are deployed radially from the central axis of the slides and inserted in the second ends of the connectors located on the inner edge of the slides. A central hole in a disk coaxial with the slides groups together the second fibers close  to  the  central  axis  of  the  slides.  Holes  spread around  the periphery of the disk group the first fibers into bundles around the central axis.

Abstract: A b s t r a c t A method and an apparatus for packaging a number of substantially cylindrical packages     consisting of a within certain limits elastic insulation material, for instance mineral wool, said packages having open ends, but being at their side faces surrounded by a substantially airtight foil layer, by which method the open ends of the packages are temporarily closed in an essentially airtight way, the volume encased by the foil layer and the temporary sealings being connected to a vacuum source to reduce the volume of the packages, the packages     thus reduced being enclosed in a tight enclosure before the vacuum is disconnected.       To use the compression by means of vacuum not only for reducing the volume of the individual packages but also for eliminating the interspaces between cylindrical packages put together, the method comprises the steps that a number of packages     are placed close to one another resting on one of the end faces in a rectangular or in par-ticular cases a quadratic pattern, the airtight sleeves touching one another, on an approximately plane surface. the outline of which corresponds substantially to the volume of the closely packed packages, and in that the packages are being closed from above with a plate     parallel there-with, at least one of the plates       being perforated at the end surfaces of the packages and the packages being pressed closely against each other in the area close to the plates       by means of holding means        ; and that the enclosure around the packages is provided by wrapping the packages in a foil after having removed the holding means and before disconnecting the vacuum.

Abstract: ABSTRACT            An apparatus and method for introducing a transmission line (5) into a duct (1) through which it is to be propelled by viscous drag of a fluid propellant. A high local flow of fluid is created by inputting fluid, preferably compressed air, adjacent the input of the transmission line to the duct and bleeding a proportion of the fluid from the duct a short distance along from the input. This local flow provides the driving force to progress the transmission line along the first third of the duct against the hydrostatic potential. the extent of the venting via the bleed valve is controllable to control the driving force on the transmission line (5). This technique is especially useful for transmission lines including optical fibres.

Abstract: ABSTRACT          Disclosed is an outside rear-view mirror for a car, having a pedestal and a mirror housing which may rock forwardly and rearwardly relaltive to the pedestal from a normal position thereof. The mirror housing has a rim proximate to the pedestal which is held against a substantially flat margin of a base plate of the pedestal under the action of a spring fastened to the pedestal and coupled to an inner portion of the mirror housing. The rearward substantially straight portion of the rim forms a rearward rocking axis with the margin, and the rim surrounds an opening of the mirror housing for passage of the spring or a transfer member coupled to the spring and the pedestal. For reducing the space necessary for the forward rocking movement of the mirror housing in cases where the mirror housing includes an acute angle with the car body when the outside rear-view mirror is mounted to the car, into the front portion of the base plate a recess is formed into which the front portion of the mirror housing adjacent to the base plate will dip during forward rocking of the mirror housing.
