Abstract: Abstract A method and apparatus is disclosed for automatically threading web material, e.g., magnetic tape, from a re-placable supply reel to a non-replacable take-up reel of a web transport device, e.g., a reel-to-reel type magnetic tape drive, in which the web path is nonlinear and relatively complex as a result of various components, e.g., magnetic transducer tape guides, which act on the web while it is being transported.            The apparatus comprises a coupling device and a me-chanism for moving and guiding the coupling device between the supply reel and the take-up reel.  The coupling device couples to a leader block attached to the tape at the supply reel.  The mechanism moves and guides the coupling device to thread the tape over the predefined tape path and positions the leader block wholly within a radially disposed slot in the hub of the take-up reel.  The coupling device remains attached to the moving mechanism and coupled to the leader block when the leader block is rotated with the take-up reel.            The method is characterized by the steps of maintaining the relationship of the coupling device to the leader block and to the moving and guiding means during rota-tion of the take-up reel when the leader block is positioned in the radially disposed slot of the take-up reel.

Abstract: ACID AND HYDROGEN PEROXIDE                         ABSTRACT         A process is described which is useful as a co-process in combination with a process which employs hydrogen peroxide.  The process of the invention provides a source of hydrogen peroxide along with a useful co-product, that co-product being 2-keto-D-gluconic acid or products derived therefrom.  One of the first and second carbons of D-glucose is oxidized enzymatically to produce hydrogen peroxide and an intermediate product.  The other of the first and second carbons of the intermediate product is then oxidized enzymatically to produce hydrogen peroxide and 2-keto-D-gluconic acid.  In one form of the invention, the intermediate product is D-glucosone; the final pro-duct is 2-keto-D-gluconic acid.  In the other form of the invention, the intermediate product is D-glucono-.delta.-lactone; the final product is a mixture of 2-keto-D-gluconic acid and D-isoascorbic acid.

Abstract: HYDRAULIC SLEEVE VALVE AND SEAL   ARRANGEMENT FOR PISTON PUMP          Abstract -To prevent leakage of wet concrete passing from a reciprocating pump to a delivery conduit and to prevent clogging of the seal and valve means interposed between the pump outlets and the mouth of the delivery conduit, a float-ing sleeve is biased by pump system hydraulic pressure into solid engagement with the wear ring which in turn is held in firm sliding contact and sealed engagement with an opposing wear plate at the outlets of the pump structure.  The float-ing sleeve is pressure sealed on opposite sides of a delivery port for pressurized hydraulic fluid to positively exclude concrete from fouling the operation of the sleeve.  Concrete grout under pressure entering a void behind the sleeve applies additional pressure to the sleeve to bias the wear ring even in the event of hydraulic pressure loss.  The grout within the void prevents the sleeve from ever backing away from the wear ring.

Abstract: ABSTRACT OF THE DISCLOSURE A method for fabricating a precision fine-line due by chemical milling the working face of an etchable workpiece to form a plurality of raised die elements separated and bounded by a plurality of cavities, is comprised of the steps of forming an etchant-resistant surface pattern of boundary grooves penetrating slightly into the working face of the etchable workpiece outwardly proximate and substantially conforming to the configuration of die element precursors, and then selectively etching the workpiece in regions outwardly bounded by the boundary grooves to undercut same and form recessed cavities outwardly proximate and substantially conforming to the complementary configuration of the die element precursors. The step of forming the boundary grooves is preferably a two stage procedure comprised of first chemical milling shal-low grooves in the workpiece in the desired pattern and then loading these grooves with an etchant-resistant fill. The region bounded outwardly by adjacent boundary grooves is etched to remove material therefrom, to expose the interface of the fill and to undercut the same  optionally inter-spersed with periodic steps to remove the fill extending beyond the undercut. The die element precursors are then chemically milled to yield a fine-line and space die.

Abstract: ABSTRACT OF THE DISCLOSURE             Bending presses equipped with the tool arrangement permit sheet blanks or metal plating to be bent in series in accordance with predetermined programs without having to perform time consuming tool exchange operations after each single operative or working step.   The tool arrangement comprises a first tool and a second two-piece auxiliary tool.          Both parts of the auxiliary second tool are subdivided into segments as is the case also for the first tool and the tool holding fixture or support and are supported at a hydraulic cushion.  The segmental matching design of the tool holding fixture, the first tool, the auxiliary second tool and the bottom dies additionally enables the two types of tools and their associated bottom dies to be simultaneously controllably directed into a respective operative position over part of the length of the bending press.  Thus, in certain cases at least two pieces of sheet metal, the width of which, when arranged in juxtaposition, is less than the total width of the bending press, can be simultaneously and differently bent using the same working stroke.  It is also possible to work at two or more stations in series.
