Disclosed is a tubular core on which sheets of metal or other material can be wound and supported, for shipment, handling and dispersal, and a method for forming the core. The core comprises a metal sheet or strip which has a rectangular-ribbed cross-sectional profile comprising rectangular, flat ribs, and which is wound spirally into a tubular configuration. The core is formed by passing the strip through a plurality of roll-forming stands, to progressively form sections of the ribs and progressively define the sections into the rectangular ribbed profile in which the flat ribs collectively form a support surface for the sheets which are to be wound on the core.

A telecommunications network for a high-rise Multi-Dwelling Unit (MDU) is provided. In the telecommunications network eliminates much of the wiring and space required for voice, video and data services, electrical closets, security cameras, building automation, fire annunciation systems, hard-wired smoke detectors, hard-wired heat detectors, electrical meters through the use of an integrated Ethernet communication system. Additionally, a video program guide (VPG) is provided that allows a user to interact with multiple streams of video in real time. The VPG includes techniques for displaying multiple streams of data on a single screen for a user.

A securing mechanism is provided for a tool that allows for the attachment and release of the shafts of a variety of implements from the tool. The mechanism has a construction that provides an easily releasable, but secure engagement of the implement shaft within the mechanism while also having an alignment feature which engages the implement at multiple locations when engaged with the mechanism to maintain the alignment and concentricity of the implement shaft with regard to the mechanism and the tool when in use.
摘要:
This invention relates to a fastener driving device including a variable ratio gear mechanism that enables the ratio of the rotation of the handle to the rotation of a driving bit extending from the handle to be varied to allow the bit to rotate at different speeds from the handle. The device includes a gear mechanism disposed within a housing for the device that includes a locking member. The locking member can be engaged with the gear mechanism to lock the gear mechanism in a configuration for a 1:1 gear ratio. The locking member can be moved with regard to the gear mechanism to provide an increased gear ratio for the gear mechanism when desired.
