Abstract: A digital memory circuit contains a plurality of areas each having memory cells disposed in matrix form in rows and columns. The columns of each memory area is subdivided into a plurality of adjacent groups which each form a segment. For each segment, provision is made of a separate set of two-conductor local data lines which lead via line switches to two-conductor master data lines common to all the memory areas. Furthermore, precharge devices are provided in order to equalize the potentials of the conductors of the local data lines and the conductors of the master data lines, the equalization potential for the local data lines being different than the equalization potential for the master data lines. A line switch control device provides for closing only of the line switches on those local data lines which belong to the segment in which a write or read mode takes place.

Abstract: A memory circuit contains areas having memory cells. To transfer memory data from/to the memory cells, two-wire local data lines are provided. Each of the local data lines is associated with one of the memory areas and is connected to a two-wire master data line, common to all the memory areas, by a line circuit-breaker. To represent the binary value of data on a local data line, the wires are driven, to first and second logic potentials. Each line circuit-breaker contains switching devices which, if one of the two wires in the local data line is at the second logic potential, autonomously transfer the potential to the associated wire in the master data line, and, if one of the two wires in the master data line is at the second logic potential, autonomously transfer the potential to the associated wire in the local data line.

Abstract: A fuel cell having an optimized flow space for the passage of hydrogen gas across the surface of an anode. The invention prevents destructive oxidation of the anode by preventing the buildup of locally high levels of oxygen. The anode surface itself may be shaped in lateral plan to follow the natural contours of gas flow to eliminate hydrogen stagnation areas on the anode surface. Alternatively, the anode surface or the cathode surface may be coated in regions of anode stagnation to prevent the fuel cell reactions from occurring in those regions. Alternatively, the gas seals may be formed to cover the anode surface in stagnation regions. Alternatively, the cathode and/or electrolyte may be shaped or thickened to reduce or prevent diffusion of oxygen ions therethrough.

Abstract: A system for cleaning a moving substrate includes a rail mounted adjacent to the substrate surface and substantially transverse to the direction of movement thereof. A carriage for supporting a contact cleaning roller (CCR) is deployed on the rail for allowing axial translation of the CCR transversely of the substrate while in rolling contact therewith. Two renewal stations for cleaning the CCR are mounted adjacent the rail, one outboard of each substrate edge. The CCR is at least twice as long as the width of the substrate and is axially oscillable for a distance sufficient that all portions of the CCR surface may be cleaned by the renewal stations during one oscillation cycle of the CCR while the CCR maintains continuous contact with the substrate across the full width thereof. The CCR mounted on the carriage may be a primary CCR and the substrate may be a continuous web or sheet, or the CCR mounted on the carriage may be a secondary CCR and the substrate may be a primary CCR or other process roller.
