Abstract: Abstract The invention provides a method for selecting hybridomas which produce antibodies specific to domains of a cell surface antigen which is usually not accessible at the surface of intact cells.          The method employs the screening of the hybridoma clones obtained for the production of antibodies specific against the cell surface antigen by use of immunoblotting analysis, namely by screening the clones against antigen immobilized on a solid substrate such as nitrocellulose.  The invention also includes those hybridomas and monoclonal antibodies when produced according to the method.

Abstract: COUNTERCURRENT ACID HYDROLYSIS               ABSTRACT OF THE DISCLOSURE          A method and apparatus are provided for the treatment of comminuted cellulosic fibrous material to effect prehydrolysis, and then subsequently kraft digestion, thereof, to produce paper pulp.  The material is steamed, entrained in liquid to form a suspension, and transferred by a high pressure feeder in a first circulation loop to the top of a first vertical vessel.  At the top of the vessel, a liquid/solids separator is provided, and the liquid withdrawn from the top of the first vessel into the return conduit of the first circulation loop includes recoverable hydrolysate (which contains hemi-cellulose, sugars, and the like).  In the first vessel, countercurrent acid hydrolysis takes place in the top of the vessel, and a countercurrent wash is effected in the bottom of the vessel.  A part of the liquid in the return conduit of the first circulatory loop is diverted to one or more flash tanks, to produce steam and a liquid with a high concentration of hydrolysate.  After hydrolysis and washing, the material is withdrawn from the bottom of the first vessel and passed through a second circulatory loop to the top of a kraft digester, preferably one having a steam phase at the top.

Abstract: ABSTRACT OF THE DISCLOSURE         A method and apparatus for inhibiting or preventing fluttering in a running paper web in a drying section of a paper machine, such as in the area of a twin-wire draw.  Air jets are blown into pockets defined by a wire guide roll and wire itself, such air jets issuing from suitably designed and positioned blow boxes to be directed at the side of the wire supporting the web either in a direction towards or opposite from the running direc-tion of the wire, and also at the side of the wire guide roll not supporting the wire, in a direction of the tangent of the guide roll.  An air jet may also be blown into the pocket defined by the wire guide roll and the wire itself, at the side of the wire running free, not supporting any web, such air jet being directed substantially perpendicular to the wire.  Fluttering of the paper web and drawbacks resulting from the same, such as wrinkles and breaks in the web, are inhibited or prevented.

Abstract: ABSTRACT          The specification describes a method of storing alphanumeric characters (including special symbols) in a graphics display terminal comprising a raster-scan display device and a refresh buffer including a plurality of bit planes (1 to 6) each having a respective bit storage location corresponding to each addressible pel position on the screen of the display device.  In the method, a first bit plane (luminance plane 1) stores high resolution luminance data defining alphanumeric characters each as a selection of "on" bits within a respective n x m array (character box) where n is the width of the character box in the scan line direction, and at least one further bit plane (attribute plane 2) stores low resolution colour data for the characters. The attribute plane (2) comprises a respective n-bit set of storage locations which corresponds to each n-bit wide by one pel deep portion of a character box in the luminance plane (1) and defines at least the colour and/or intensity of the foreground and background of the character for the width of the character box in respect of a single scan line. The specification also describes a graphics display terminal in which data in the luminance and attribute planes may be selectively decoded either as alphanumeric data stored as above, or as bit-mapped graphics data.

Abstract: Abstract of the Disclosure A method and apparatus for producing a video composite blanking signal which provides for selectively unblanking lines of video information which wouldnormally be blanked according to a predetermined television standard. Each line in a frame of video data is assigned a line type based on its location in the sequence of lines of video information. Those lines that are in the vertical blanking period are assigned a different line type than those which are not. In response to unblanking selection data, line types of lines which are normally blanked are selectively modified to the line types of those lines which are not normally modified. The vertical interval blanking signal is produced only for those line types for line in the vertical blanking period.
