    摘要: A roll for a rolling mill capable of an on-line control of the width thereof. The roll includes a drive roll connected to a mill motor and a hollow driven roll driven by the drive roll while being axially slidable with respect to the drive roll. A screw shaft is screwed to the inside of the hollow driven roll in such a manner that an end-to-end contact of the driven roll with the drive roll is obtained. A clutch is provided for a selective locking of the screw shaft, which is unlocked during a normal rolling process, so that the screw shaft is rotated together with the drive roll and the driven roll by a rotation of the mill motor. When adjusting the roll width, the clutch is operated so that the screw shaft is locked, and as a result, a rotation of the mill motor causes a mutual axial movement of the drive roll and driven roll to thus adjust the roll width. A means is also provided for a centering of the roll at the pass line of the material, after the adjustment of the roll width.

    摘要: A device for developing an electrostatic latent image recorded on a photoconductive layer. The developing device comprises a doner roll for supporting a uniform layer of single-component developing material adjacent to the photoconductive layer. The doner roll is disposed as to create a space gap between the photoconductive layer and the doner roll. The doner roll is made of semiconductive material having a specific resistance ranging from 10.sup.6 to 10.sup.12 .OMEGA.cm. An electrical bias potential is applied across the gap, thereby establishing a field for transferring the developing material from the doner roll to the photoconductive layer.

    摘要: A granular fibre-free microporous thermal insulation material, having a thermal conductivity less than 0.05 W/mK and a shrinkage of not more than 10%, which is free flowing and consists of granules of an intimate mixture of: 30-95% dry weight microporous insulating material; 5-70% dry weight infrared opacifier material; 0-50% particulate insulating filler material; and 0-5% binder material. The material is made by mixing together the microporous insulating material and the infrared opacifier material to form an intimate aerated mixture with a first density; conveying the intimate mixture at a first volumetric flow rate to an extrusion means (5); extruding the intimate mixture as a compressed material with a second density greater than the first density at a second volumetric flow rate lower than the first volumetric flow rate; venting a proportion of air from the aerated intimate mixture through a porous membrane to relieve pressure generated within the intimate mixture due to the change from the first volumetric flow rate to the second volumetric flow rate; and granulating the compressed material.
