Abstract: The invention relates to a method and apparatus for correcting register faults in a multicolor printing machine (1) having a number of items of equipment (2,2′, . . . ) for the digital production of color separations (3,3′, . . . ), correction values being determined and assigned to the angular positions (4,4′, . . . ) of at least one image cylinder (5,5′, . . . ) and, as a result, being taken into account for the control of the production of the color separations (3,3′, . . . ) on said image cylinder.

Abstract: The invention relates to a method and apparatus for setting register in a multicolor printing machine (1) having a number of items of equipment (2, 2′, . . . ) for the digital production of color separations (3, 3′, . . . ), the actions of setting up and combining the color separations (3, 3′, . . . ) being controlled, in order to set the register, in such a way that in-register prints are achieved.

Abstract: The invention relates to a method and apparatus for setting register in a multicolor printing machine (1) having a number of items of equipment (2, 2′, . . . ) for the digital production of color separations (3, 3′, . . . ), the print results being registered and used to control the production of the color separations (3, 3′,. . . ) in such a way that in-register prints are achieved, and a change in the dimensions (7, 8, 7′, 8′) of the printing substrates (4) being determined by means of the print, in order to take this change into account for renewed printing.

Abstract: The invention relates to a method and apparatus for minimizing the influence of register differences in multicolor printing, in particular in digital printing processes, register values (1) in the transport direction (2), which are different transversely with respect to this direction being set to a value between the extremes (3, 3′).

Abstract: A gear shaft assembly for use with a pump and a method of making the same are gear shaft of the present invention. The disclosed assembly includes a housing, a stepped shaft, and a gear rotationally disposed on the shaft. The shaft has a first end disposed in a first bore defined in the housing and a second end in threaded engagement with a second bore of the housing. A first shoulder of the shaft disposed adjacent the first end engages a portion of the housing to define a fully inserted position of the shaft. The gear is disposed on an intermediate section of the shaft between the first shoulder and a second shoulder located adjacent the second end.

Abstract: Any deterministic finite-state automata (DFA) can be implemented in a sparse recurrent neural network (RNN) with second-order weights and sigmoidal discriminant functions. Construction algorithms can be extended to fault-tolerant DFA implementations such that faults in an analog implementation of neurons or weights do not affect the desired network performance. The weights are replicated k times for k-1 fault tolerance. Alternatively, the independent network is replicated 2k+1 times and the majority of the outputs is used for a k fault tolerance. In a further alternative solution, a single network with k.eta. neurons uses a "n choose k"encoding algorithm for k fault tolerance.

Abstract: A generating milling cutter including a supporting body having a plurality of circumferentially and, if desired, axially spaced supporting teeth, each having a radial seat surface and a second seat surface which extends at the root of the supporting teeth substantially perpendicularly thereto for receiving cutting blades or cutting ledges of heavy duty material adapted to be mounted to the teeth. The seat surfaces of the cutting blades or cutting ledges cooperate with a rearward first abutment surface and a lower second abutment surface. The cutting blades or ledges include at their rearside at least a third abutment surface which extends transversely to the rearward first and second abutment surfaces and cooperates with at least one complementary third seat surface of the supporting teeth.

Abstract: A process for the chlorine-free bleaching of pulps in an aqueous suspension which comprises forming the suspension with a consistency of 3 to 20 mass percent; introducing into the suspension an ozone-containing gas having an ozone content of 20 to 300 g/m.sup.3 in an amount corresponding to at most 2 mass percent ozone calculated on dry pulp of the suspension during vigorous agitation of the suspension to form a reaction mixture; maintaining a pressure of the ozone-containing gas at a pressure of 1 to 15 bar during introduction into the suspension; and controlling reaction conditions during contact of the ozone-containing gas with the suspension to maintain a reaction temperature of 15.degree. to 80.degree. and a pH value of 1 to 8.

Abstract: A three-stage bleaching process for dissolving grade pulp utilizes the sequence OP(alkaline)-Z-P and the off gas from the Z-stage is delivered to the alkaline (OP)-stage whose parameters are controlled to fully react all of the oxygen of the off gas. The filtrate or waste water from the Z-stage, at a pH below 3, serves to dilute the alkaline OP-stage pulp before Z-stage bleaching and/or for de-ashing of the P pulp following the P-stage.

Abstract: A stamp vending machine has a number of stamp dispensing mechanisms. Each mechanism is capable of dispensing one or more stamps of the same denomination. The machine can dispense from one mechanism different numbers of stamps and from a number of different mechanisms stamps of different denominations in various combinations totalling the same price or different prices. This capability is provided in a programmable manner that is easily changed to other combinations of numbers of the same stamps or to the operation of different combinations of stamp dispensing mechanisms. The construction of the machine preferably includes the capability of providing a backup of one of its stamp dispensing mechanisms by another mechanism or by more than one mechanism in sequence.
