Abstract: Abstract:    Sulfur oxides contained in the flue gas from coal-fired boilers are adsorbed by an adsorbent prepared by dry-distilling a portion of the fuel coal satisfying at least one of the following requirements:  an ash content lower than 15 % by weight and a fixed carbon content of at least 50 % by weight; thereby producing semi coke, and activating the semi-coke by steam.  After use, the adsorbent is heated to desorb the adsorbed sulfur oxides in a high concentration.  The desorbed sulfur oxides are passed through a bed of semi-coke before the activation to recover the sulfur oxides as elemental sulfur.

Abstract: O.Z. 0050/034517 Abstract of the Disclosure:  A process, carried out without a diluent or in solution, in more than 2 reaction zones, for the continuous preparation of rubber-modified polymers of vinylaromatics, wherein a monomeric aromatic vinyl compound and an elastomeric polymer, in an amount of from 3 to 16% by weight based on the monomer, are polymerized, in the absence of a free radical initiator, but in the presence of a mercaptan as a chain transfer agent, at from 80 to 180°C in a first reaction zone, with stirring, up to a maximum monomer conversion, Umax, given by the equation Umax = K - 1 where K is the amount of rubber in % by weight based on monomer, and, in a second reaction zone, polymerization is continued, with stirring, to a conversion of up to about 50% by weight, after which a chain transfer agent is introduced in an amount of from 0.01 to 0.2% by weight, based on vinyl-aromatic monomer, and polymerization is continued, if appropriate in more than one reaction zone, up to a monomer conversion of less than 85% by weight. The polymer is treated in a devolatilization zone to remove vinyl-aromatic monomer and solvent, if any, and these constituents are recycled to the process.          The process claimed makes it possible to prepare products which exhibit good gloss coupled with good mechanical properties, and which can be employed for con-ventional applications.

Abstract: TITLE                      RANDOM SELECTION DEVICE                           INVENTOR                        Richards NEILANDS                           ABSTRACT     A random selection device selects a given number of tokens, in sequence from a preselected quantity of tokens by the simple expedient of a hollow spheroid defining a plenum, and having a retractable or telescopingly hollow cylinder, one end of which is closed, the other end of which is open to communicate constantly with the plenum.  The hollow cylinder telescopingly extends through an aperture in the spheroid wall so that its closed end may be retractably positioned into juxtaposition with the surface of the wall whereby the cylinder is deployed in the plenum; or, in its operative mode, in extension, whereby the cylinder is fully withdrawn from the plenum yet in communication therewith.   Within the plenum of the spheriod there are the predetermined quantity (a given number) of spheres of equal diameter each of which is embossed or imprinted with its own unique indicia thereon.  Preferably the spheres arc imprinted with the denominational indicia; numbers, letters, or combination of both.  When the cylinder is withdrawn from the plenum into its remote position, a predetermined number of spheres can be sequentially placed into the hollow  cylinder since the internal diameter thereof is sized just slightly larger than the outside diameter of the spheres.  The actual number of spheres positionable within the cylinder is directly determined by the length of the cylinder (relative to its internal diameter).

Abstract: ABSTRACT        The invention provides an agitator for releasing powder toner through a bottom opening of a hopper.  The agitator has a screen for placing over the opening and an element which, when positioned in the hopper, is in contact with the upper surface of the screen.  Toner normally bridges the openings in the screen so that there is normally no flow through the screen and the element is operable to brush over the upper surface of the screen to break down the bridging locally, thereby effectively sifting powder toner through the screen.  On stopping the element, the toner again bridges the openings and flow of toner stops.  The invention also provides a feeder which magnetically transports toner received from the hopper, and an applicator which takes the toner magnetically from the feeder and transports the toner to the point of use.
