Abstract: A telecommunication distribution frame is provided for optical fiber of an incoming cable. Primary and secondary flexibility suites include joined blown fiber tubes routed as desired within the installation. A continuous blown fiber unit may extend through the joined blown fiber tubes. A blown fiber tube flexibility module may have a patching panel which may be provided with connectors. Above the panel may be a set of bend control vanes or mandrels one for each of the connector sites in the panel. Patching tubes may pass down and out through an aperture at the back of the module.

Abstract: A device for use with apparatus for installing a cable into a tube, the apparatus including means to mechanically drive the cable into the tube, the device being suitable for directing an air flow into the tube and comprising a bore into which the air flow is directed, the bore having a length and a longitudinal axis, shielding means to reduce air flow from the bore along the longitudinal axis of the bore, wherein the shielding means extends the length of the bore, and wherein the bore is formed from the shielding means.

Abstract: A blowing head for installing an optical fibre unit into a tube, including driving means for driving the optical fibre unit into the tube, the driving means having a plurality of driving surfaces, wherein one or more attic plurality of the driving surfaces are resiliently biased with a predetermined force toward the other driving surface or surfaces, and wherein in use the optical fibre unit moves between the plurality of driving surfaces.

Abstract: A printer apparatus and method of actuating a fluid pump in a printer to deliver fluid to an ink jet printhead without removing the printhead from a printhead carriage particularly useful for priming inkjet printheads using an air displacement pump to deliver air under positive pressure to the printheads. The pump is located proximate a service station on the printer and is automatically actuated by movement of the carriage to service station. The pump may be arcuately positionable to align the pump with a selected one of air passageways provided in a printhead holddown cover on the printhead carriage. Algorithms are provided for locating the precise position of the pump outlet along the carriage scan axis relative to its intended design location and for arcuately positioning the pump relative to the carriage to engage the pump outlet with a selected one of conduits in the carriage connected to each printhead.

Abstract: A printhead carriage for an ink jet printer having a plurality of printhead stalls therein and a printhead holddown cover having spring biased printhead holddown plungers on the underside of the cover and equal volume fluid passageways in the cover for conducting fluid from fluid inlets on said cover exposed to atmosphere to printheads in the stalls. An arcuately moveable air pump is engageable with one of a number of arcuately positioned inlets to the passageways in the carriage cover to enable a single pump to selectively apply positive pressure to prime each of the printheads in a desired sequence.
