Abstract: ABSTRACT OF THE DISCLOSURE A press roll in a paper making machine comprises a non-perforated  inner  frame  onto  which  an  elastic layered  structure  is  applied,  the  layered  structure including an inner layer having a volume of which a substantial portion is constituted by cavities and an outer layer adapted to act against the inner surface of a looped press felt which passes through the press nip, the outer  layer having passages  formed therethrough which communicate with the cavities of the inner layer. During operation, the cavities are compressed together and  thereby  widened  or  extend  the  nip  zone  and, additionally, the cavities act as suction devices to produce a negative pressure in the nip zone following the center line thereof.  A press is disclosed which is formed  by  the  press  roll  described  above  and  a counter-roll which is provided with an elastic coating and a hollow face.  A pair of press felts pass through the nip zone formed by these rolls between which the web to be detoured is passed.

Abstract: ABSTRACT OF THE DISCLOSURE:            There is described a method for producing a preparation having a high content of Factor VIII(AHF), i.e. with a specific activity of at least 1.5 units of Factor VIII/mg protein, immunoglobulin G (IgG) of from 15 to 30 mg/1000 units of Factor VIII and fibrinogen of from 20 to 20 mg/100 units of Factor VIII.          The method consists in that a Factor VIII containing plasma fraction is dissolved in a buffer, the solution is purified from undesired proteins by precipitation and is concentrated, the precipitation of undesired proteins being carried out in the presence of sulfated polysaccha-ride at a pH of from 6 to 7. After separation of the un-desired proteins, a Factor VIII concentrate is precipi-tated, dissolved and processed into stable form. If de-sired, an antithrombin III-heparin complex or an anti-thrombin III-heparinoid complex is added to the solution.

Abstract: ABSTRACT OF THE DISCLOSURE    Thin-wall, corrugated pipe having alternating, annular ridges and valleys along its length is bent between a pair of die parts selectively to reform the normal configuration of a valley and change the linear distance between segments of a pair of ridges adjacent said valley thereby to form an incremental bend in the pipe.  Thereafter, a predetermined number of incremental bends are formed in consecutive valleys to obtain a desired angle of bend.  A radial angle fixture is engaged on one end of the pipe to determine and maintain the radial position of the pipe during the bending of the pipe, and a bend angle protractor is provided to determine precisely the angle to which the pipe is bent.  The radial angle fixture further serves to maintain the pipe entering the bending tool perpendicular to the plane of the pair of dies.

Abstract: Abstract Treatment of soil A process for treating soil which comprises applying to the soil an aqueous solution of a formaldehyde-based pre-condensate containing a condensation initiator in an amount sufficient for condensation to be completed within a pre-determined period of time not exceeding 24 hours. Prefera-bly a urea-formaldehyde pre-condensate is used. Advanta-geously the solution also contains a polysaccharide (alginic acid, alginate, low methoxyl pectin, gum karaya, gum arabic) which is capable of forming a gel with divalent metal cations, particularly calcium, present in soil.         The treated soil has improved erosion resistance.

Abstract: Abstract:          In a magneto optical file memory, a storage medium having a vertical magnetic film is irradiated with a laser beam to reverse a magnetization direction of the magnetic film, thereby to write and/or erase information.  Rotation of a polarizable face of reflected light from the storage medium is detected to reproduce the information.  A leakage magnetic field of an actuator that controls an optical system for condensing the laser beam on the storage medium is set to have the same sense as that of the initial magnetization of the magnetic film.  The result is a system in which writing, reproduction and erasure can be precisely conducted, and in which use of the leakage field to aid erasure enables the magnet coil used for writing and erasure to be kept small.

Abstract: ABSTRACT OF THE DISCLOSURE   A novel composition for the encapsulation of particles is provided herein.  The composition includes at least one particle, such particle comprising an active-substance-containing, solid or liquid core encapsulated by a polymer or copolymer.  The composition is obtained by treating at least one solid or liquid, active-substance-containing particle by adsorbing thereon at least one amphipathic compound.  Such amphipathic compound either is capable of acting as an initiator in cationic polymerisations or, if the  amphipathic compound is not itself capable of acting as an initiator in cationic polymerisations, then the amphipathic compound is activated with a Bronsted or Lewis acid so that it can function as an initiator in cationic polymerisations.  Such at least one treated particle is then encapsulated by the in situ polymerisation or copolymerisation thereon of at least one cationically-polymerisable monomer or prepolymer.  This provides, for example, a controlled release composition which can provide sustained or pulsatile rates of release of active substances.

Abstract: ABSTRACT            A printer prints characters by printing selected charac-ter elements in a matrix of print positions arranged in horizontal rows and vertical columns.  The printer includes storage means for storing sets of character data elements which are used for printing the character ele-ments.  The printer also includes logic means for selec-tively performing logical operations on the sets of character data elements in order to vary the sets of character data elements in accordance with certain rules and thereby vary the print quality in the horizontal, vertical and diagonal directions of the characters which will be printed using the stored character data elements.      The stored sets of character data elements are selected so that they can be used for printing characters which have a high print quality in the horizontal direction and a low print quality in the vertical and diagonal directions.      In order to print characters in a low print quality the logic means derives subsets of the stored sets of charac-ter data elements and only these subsets of character data elements are used for printing characters.            In order to print characters in a high print quality the logic means performs logical operations on the stored sets of character data elements so as to generate addi-tional character data elements.  These additional character data elements together with the stored charac-ter data elements are used for printing characters.
