Abstract: A blending equipment mounted on the ceiling of a blending bin has a conveyor airduct for introducing materials or raw cotton from the exterior of the blending bin into the interior thereof. The conveyor airduct has a lower end with which one end of a spreader outlet is communicated, the other end of the spreader outlet being opened laterally within the blending bin. The opening of the spreader outlet turns round a vertical axis. A lower member of the spreader outlet defining the opening is moved up and down. Rotation of the spreader outlet and oscillation of the lower member of the spreader outlet are effected simultaneously. Thus, the materials fed into the blending bin through the conveyor airduct are evenly scattered from the opening of the spreader outlet not only at a position below the blending equipment but also set positions more remote therefrom.

Abstract: A connector having two connector portions which are adjustably connected together to be in aligned relationship and with each portion receiving the respective ends of optical fibre lines to be connected together in abutting and aligned relationship. At least one connector portion has an inner collar in which the end of the fibre is disposed to lie in eccentric relationship to the longitudinal axis of the collar. This inner collar is rotatably disposed in a hole in an outer collar with the hole being eccentrically disposed with respect to the longitudinal axis of its outer collar. By angular adjustment of the inner and outer collars with respect to each other the respective ends of the optical fibre lines can be positioned with respect to each. At least one inner collar can be of transparent material so that optical leakage occurring at the connector can be easily detected.
