摘要:
A wire line includes a flyer payoff and means for controlling the wire discharged from the flyers payoff by a tension system comprising two spaced tensions, the first of which comprises two groups of rolls with the rolls of one group staggered with relation to the rolls of the other group with the groups relatively movable toward and from each other to apply more or less tension on the wire as it leaves the flyer payoff with the tension system also including a second tensioning means comprising a drum and a guide sheave spaced therefrom about which the wire is passed with sufficient surface engagement with the drum and sheave so that they will rotate as the wire passes thereover rather than the wire slip on either, and then applying a friction drag on the drum to retard the rotation and apply a greater amount of tension before the wire passes on to a point to be serviced.

Methods and apparatus for the interactive display of images and measurements of samples. A user may interact with embodiments of the present invention to display measurements for a set of biological samples and subsequently display images associated with particular biological samples of interest. For example, selecting data indicators in the set may result in the display of an image associated with a biological sample as well as one or more overlays presenting information of interest as well as controls affecting the display of the image or the information.
