Abstract: Abstract of the Disclosure A process for after-treating an offset printing plate, which has preferably been obtained by transferring a silver image by the silver complex diffusion process to the surface of a metal plate and which has hydrophobic printing areas and hydrophilic non-printing areas is provided.          The aftertreatment is carried out by applying a protective lacquer only to the hydrophobic printing areas.          As protective lacquer there is used a solvent-free, photopolymer-isable system which consists substantially of at least one ethyl-enically unsaturated photopolymerisable monomer and/or prepolymer, photoinitiator and optionally a polymerisation catalyst. The plate which is coated imagewise with the photopolymerisable pro-duct is then exposed until the polymerisable product has solidi-fied. The offset printing plate thereby obtained shows a good mechanical stability and is particularly resistant to abrasion.

Abstract: ABSTRACT OF THE DISCLOSURE           A method of forming an anchor member for use in a concrete prestressing anchorage is disclosed.  The method includes the provision of plate means formed with a bore therethrough, positioning of a tubular conduit means in the bore, and urging of the conduit against the side walls of the bore to radially deform the conduit and bore into a tapered bore suitable for mounting of tendon gripping wedges therein.  The urging step not only forms the taper in the bore, but also effects securement of the conduit to the plate.  The conduit may be positioned to extend from either or both of the front or rear sides of the plate to provide or enable securement of auxiliary structures to the anchor member, e.g., means for mounting of the anchor member to a form board.  The method employing the conduit may be used to effect securement of a plurality of plate-like elements together to form a unitized anchor plate.

Abstract: POWER SWITCHING CONTROL CIRCUIT   WITH ENHANCED TURN-OFF DRIVE     ABSTRACT     A transformer-coupled power switching device con-trol arrangement utilizes an active feedback energy source connected to the primary of the coupling transformer to en-hance the turn-off drive to the power switching device.  The active feedback energy source produces an output directly dependent upon the magnitude of the power switching device output current and independent of the duration of said out-put current.  When the output current drops to zero, the active feedback source is disabled, and a bias network is connected to the transformer primary.  The bias network maintains a reverse voltage at the control electrode of the power switching device and establishes a bias current through the primary suitable for resetting the transformer core flux.
