AbstractThe SideWinder is a power delivery system for a hand-coring ice auger. It not only greatly increases the rate of drilling, it also makes it possible for a single operator to drill to depths difficult and cumbersome for hand-coring systems. The SideWinder power is delivered by an electric drill that is used for both the drilling and the lifting of the drill string. A high-strength low-stretch synthetic-fiber rope lifts and lowers the drill string as it winds around a tube attached to the electric drill. During winding, the synthetic-fiber rope is guided onto the winding tube by rope cleats that also serve as a quick way to secure the rope for drilling. The end of the winding tube connects directly to the protruding extension of the drill string for drilling. The rope always remains attached to the drill string by a rope-pin that replaces the bottommost connecting pin; the winding tube holds the rope and always stays attached to the electric drill. For lifting and lowering the drill string, cradle arms on a frame that hinges on a plywood platform hold the winding tube.

Dfb Laser

This article assembles a distributed feedback (DFB) cavity on the sidewalls of the optical fiber by using very simple fabrication techniques including two-beam interference lithography and dip-coating. The DFB laser structure comprises graduated gratings on the optical fiber sidewalls which are covered with a layer of colloidal quantum dots. Directional DFB lasing is observed from the fiber facet due to the coupling effect between the grating and the optical fiber. The directional lasing from the optical fiber facet exhibits a small solid divergence angle as compared to the conventional laser. It can be attributed to the two-dimensional light confinement in the fiber waveguide. An analytical approach based on the Bragg condition and the coupled-wave theory was developed to explain the characteristics of the laser device. The intensity of the output coupled laser is tuned by the coupling coefficient, which is determined by the angle between the grating vector and the fiber axis. These results afford opportunities to integrate different DFB lasers on the same optical fiber sidewall, achieving multi-wavelength self-aligned DFB lasers for a directional emission. The proposed technique may provide an alternative to integrating DFB lasers for applications in networking, optical sensing, and power delivery.
