Abstract: ABSTRACT   The invention relates to a process and device for backfilling of a roadway structure of mine and tunnel construction utilizing support hoses filled with a hardening filler.  The hoses, when empty, are supported by the roadway support, after being put in place on the support are filled and thereby stretched out to form an inflated profile which locks onto the sup-port section.  The process and device used has the advantages of not being limited to certain specific support structure spacings and may be applied to a variety of roadway sections.  The support section has the general shape of an I-beam and when used in multi-part roadway structures the section junctions are protected against overloads even when they are designed with limited yieldability.  The support hose is laid on and supported over part of its length directly by the outer face of an "I" beam support section flange facing the rock.  Where the flange supports the hose, the support section flange wholly or partly indents the cross-section contour of the inflated profile when the support hose is stretched out as it is filled with the hardener compound.

Abstract: Title of the Invention AUTOMATIC DEVELOPMENT ELECTRODE         BIAS CONTROL SYSTEM                 Abstract of the Disclosure An automatic control system for the bias on a development electrode in which a plurality of ground-insulated, narrow floating electrodes are spaced along a line adjacent the entrance of a liquid developer applicator unit. The floating electrodes relatively scan image areas of the surface of an organic photoconductor carried by a conductive support moving through the developer unit. Owing to conduction of a charge from the photoconductive surface through the developer liquid to the floating electrodes, they assume potentials each of which is a function of the average potential of the image area subtended by the floating electrode. The potential of each floating electrode is sensed by a high input impedance measuring circuit which selects the potential of the low-est value, amplifies the selected potential and applies the amplified voltage to the biasing electrode or electrodes of the developer system.    A fully charged and unexposed area of the surface following the image area produces a reverse bias which cleans the biasing electrodes as the fully charged area passes through the developer system.
