Bending Losses in all Solid 2D Photonic Band-Gap Fibers: A limiting Factor?

Abstract: Bending losses are investigated experimentally and numerically in a solid-core bandgap fiber with parabolic refractive index inclusions Previous record of 20 dB/km is reduced to 6 dB/km by increasing the fiber bend radius

A multifilamentary Nb 3 Sn dipole magnet

Abstract: A one meter long, 8 cm aperture dipole magnet has been constructed from prereacted Nb 3 Sn multifilamentary conductor. The conductor is in the form of a wide braid formed from 95 wires of 0.3 mm dia. each containing 1045 filaments of niobium in a copper-tin matrix. After braiding and compacting the conductor was heat treated to form the Nb 3 Sn filaments. The braid was then wound into a dipole of the ISA type using techniques similar to those employed in the construction of magnets from the more conventional NbTi braid. Voltage taps were attached to the conductor at appropriate positions so that the effect of mechanical stress could be observed at the bends of greatest curvature. The effective resistivity of the bent regions of the conductor showed a marked dependance on the bend radius varying from 7 × 10-10ohm-cm at a radius of 0.6 cm to approx, 10-10ohm-cm at 1.0 cm measured at a field of 3 T and a current density of 3.7 × 104Amps/cm2. While the bending of the conductor during coil fabrication did lead to some damage of the Nb 3 Sn filaments, it was not the factor limiting coil performance. The connection between the coil halves in the magnet was resistive and limited the maximum coil current to 2650 amps, well below the short sample limit. An improved method of coil interconnection is being used in future magnets in this series and should make it possible to extend the measurements to higher fields and current densities.

Heating pipe coil for area, esp. floor, heating - the flexible heating pipe being fixed to a building component by a flanged plastics mounting

Abstract: Laying a heating coil pipe for area, esp. floor, heating, features fixing the flexible (yielding) heating pipe by means of a mounting fitted to a building element. The mountings used are such as have a bend corresponding to the practicable bending radius of the heating pipe, so as to guide same, and a flange for securing it to the building element. The mountings are fastened at 2 opposite sides of a surface to be heated, in spaced relationship. The heating pipe is laid, meander fashion, about the mountings. Rapid and economical installation of floor heating systems is obtained.

Cable type remove control device and remote control system employing the same device

Abstract: PURPOSE:To reduce a control force, to reduce the size of a cable, to decrease a bending radius, and to enhance the degree of freedom of cable wiring by a method wherein a servo assist mechanism is mounted on the driven side or in the middle of a force transmission route formed by using a cable. CONSTITUTION:When a control lever 6 of an input mechanism 1 is operated in a direction A, torque in the direction A is exerted on an input pulley 7 of a servo assist unit through an input cable 18. The torque is transmitted to an output pulley 9 through the one strain absorber 8, but simultaneously a pressure-sensitive sensor incorporated in the strain absorber 8 is worked. When an electromagnetic clutch 10 is engaged through a controller C and a motor M is also run in the direction A. Thus, solely by exerting a force, being low enough to allow working of the pressure-sensitive sensor, on the control lever 6, an object 3 to be controlled is controlled by means of a high power generated through a standard cable. Since, when the control lever 6 is stopped, the pressure-sensitive sensor does not detect a pressure, the electromagnetic clutch 10 is immediately disengaged, and the motor M is stopped.
