Abstract: Abstract of the Disclosure Effluents in a chlorine based pulp bleaching plant arc puri-fied by treatment in a bed containing a particulate, weakly basic anion ex-change and/or absorbent resin which takes up coloured lignin degradation products from the effluent.  Subsequently the resin bed is eluted by means of an alkaline solution, a portion of the eluate released from the resin bed being acidified to a pH of less than about 2 to precipitate part of the solids of the effluent.  The precipitate is separated from the residual acidic liquor and transferred to a recovery plant for eventual disposal.  The chlorine content of the precipitate is relatively low, thereby reducing pollution and corrosion problems during the disposal.

Abstract: ENLARGER-PRINTER     ABSTRACT OF THE DISCLOSURE  An enlarger-printer wherein aperture cards, each mounting a microfilm are fed one after another from a card hopper, moved in the direction in which the major sides of the cards are oriented and scanned in the direction in which the minor sides of the cards are oriented, so that imagewise exposing of the photosensitive member can be effected for each card to form an enlarged latent image of the film of each card on the photosen-sitive member,which latent image is then converted into a visible image.  Before each card is scanned, the card is moved upwardly a distance corresponding to the margin between the image and the upper edge of the film to reduce the time required for effecting scanning.          Switching between lenses of different magnifica-tions, exposing slits of different widths and scanning speeds consistent with desired magnifications of the image can be effected simultaneously  by simply actuating a lever.  A mark reader may be provided so that these switching operations can  be performed auto-matically,prior to effecting exposure by reading a mark on each aperture card.  The aperture cards are stacked, after being passed through various steps, in a position which is higher than the optical system of the lenses.  The used cards are stacked in the same order and face the same direction as when they were held in the card hopper.  Each of the reflectors for reflecting the light emanating from a light source can be withdrawn from the main body of the enlarger-printer lengthwise thereof, and does not require adjustments of its position when inserted in the enlarger-printer again, so that damage to the surface of each reflector, which might otherwise be caused in inserting and with-drawing,it can be avoided.

Abstract: ABSTRACT OF THE DISCLOSURE A hand held masking machine is provided which is used for masking various surfaces adjacent to which paint is to be applied.  The machine may be used on d wall adjacent a ceiling so that the ceiling may be painted without contacting the adjacent wall with a brush or overlapping with a spray paint. The hand held masking machine in accordance with a broad facet of the present disclosure is provided with a frame  having offset portions holding a tape roll holder and a paper roll holder with their ends offset. The tape is thus dispensed  in such a manner that part of the tape adheres to the paper on the roller and the rest of the tape overlaps the  paper be-yond the edge of the paper roll and beyond the edge of the paper dispensed therefrom.  The paper and tape is dispensed in adhered relation each other and the tape is then adhesively engaged with a surface to which it is applied.  Following this, the machine is moved with the tape and the paper in tension which pulls the paper and tape from the machine in adhesively connected relationship.  A guide bar on the forward portion of the frame wipes the adhesive tape securely  into adhesive relation with the surface being applied as the machine is moved along said surface.  This provides a hand held masking machine which is of light weight and which is compact and easy to operate.  It readily dispenses paper and tape adhesively received together without the need of pressure rollers for pressing the tape onto the paper and for pressing the paper and tape onto the surface being masked. It is very simple to load and does not require complicated operation to thread the paper and tape through the machine, position for duplication of the paper and tape to a surface being masked.  The machine is very rapid in use and is therefore capable of masking large areas with a minimum of manual labor time.

The stabilizing substrate of each section of the electrical portion and of the shield are formed by local segments of a stabilizing material.  The segments are separated by a material of a lower electrical conductivity than the stabilizing material, the resistance of the stabilizing substrates within each section being in excess of the impedance of the electrical portion of this section.          Both the cores of the electrical portion are electrically connected at least in the points intended to be used for connection of terminal devices.  The inner core is made of a normal metal and the thickness of the stabilizing material of the substrate is not in excess of the effective depth of penetration of alternating current.  The proposed cable can find its practical utilization in superconducting transmission systems.
