Abstract: ELECTROPHOTOGRAPHIC METHOD FOR PRODUCING     BLACK AND COLOR SEPARATION IMAGES    Abstract of the Disclosure An electrophotographic method is disclosed for forming a black (or neutral) toner separation image and a color toner separation image from a sin-gle original without cross-contamination of black toner in the color separation image and vice versa. The method entails composing an original containing "false-color" information - other than black or neu-tral - corresponding to the black separation image desired and color information corresponding to the color separation image desired.  The false-color and color information are selected to absorb actinic light in mutually exclusive wavelength regions of the spectrum.  When the original is illuminated, for example, with light having wavelengths in the false-color absorption region only, a light pattern is formed and employed to expose a charged photorecep-tor.  The resulting electrostatic image is developed with black - or neutral - toner, thereby forming the black separation image.  On the other hand, when the original is illuminated with light of wavelengths in the color information region only, the light pattern produced establishes a different charge pattern when used to expose a charged photoreceptor. The latter charge pattern is developed with a colored toner.         The black and color toner separation images form a composite image without toner cross-contamination when transferred in register to a receiver.

Abstract: ABSTRACT     Steam generating systems in which steam and water wetted components are fabricated from corrosion resistant materials.  This reduces the requirement for chemical feedwater treatment to removal of dissolved solids from the feedwater.  Ion exchange resins are employed for this purpose to remove contaminants from both condensate and make-up water.  Feedwater treatment is completed by filtering suspended solids from the condensate and make-up water and by utilizing hot well deaeration as necessary to reduce the dissolved gases content of the feedwater to an acceptable level.

Abstract: MAGNETIC BUBBLE MEMORY DEVICE               ABSTRACT OF THE DISCLOSURE      A magnetic bubble memory device consisting of major/minor loops comprises at least one boot loop and minor loops.  Data stored in the boot loop as a form of bubble are controlled by the reading out of the data independently from the minor loops.  Header data are stored in the boot loop.  Faulty loop data of the minor loops is stored in the minor loops with a certain positional relationship based on the header data.  This results in allowing the device to be applied to a memory having a larger capacity, a higher production yield, and a high-speed detection time for faulty loop data.

Abstract: Abstract:            Method and Apparatus for Reducing the Energy Consumption when Drying a Paper Web A paper web (1) of low grammage is formed on a fabric (3) in the wet end of a paper machine, picked up from the fabric (3) by pick-up means (9, 11), and after the picking-up is conveyed to and through the drying section (13, 15) of the paper machine. To reduce the energy consumption for the drying in the drying section the web (1) is divided by means of edge cutters (25) into a trimmed web (1a) and couch trimmings (1b) while it is being conveyed on the fabric (3). Thereafter the trimmings (1b) are retained on the fabric (3) by means of suction means (27) when the trimmed web (1a) is picked up from the fabric (3) to be conveyed to and through the drying section (13, 15), and finally the retained trimmings (1b) are removed from the fabric (3) by means of a wire roll (41) located externally of the fabric loop. Said suction means comprise a suction box (27) having a suction slot (31) of a length that substantially corresponds to the width of the couch trimmings (1b), and the suction box (27) is located some few millimetres (A) below the plane (39) of the fabric (3) and is able to develop a suction force that is sufficient to displace the fabric edge portion, which carries the couch trimmings (1b), from the plane (39) of the fabric in the area of the picking-up of the trimmed web (1a) from the fabric (3). Hereby you avoid on one hand web breaks and similar problems, and on the other hand that the couch trimmings (1b) are picked up from the fabric (3) together with the trimmed web (1a).
