  • Patent number: 4488952
    Abstract: A method of removing sulphur from coal prior to burning of the coal is the subject of the present invention. The coal is first comminuted to a size of no more than one inch and preferably one-half inch in diameter. The coal particles are placed in a reaction chamber in an aqueous suspension to which is added an inorganic base capable of reacting with hydrogen sulphide in order to neutralize the latter, such base preferably being calcium hydroxide. A photoelectric catalyst, characterized by structural imperfections to provide active sites for supporting a free radical reaction, is also introduced into the reaction chamber. The coal is then subjected to electromagnetic irradiation of a specific energy level in order to create a free radical reaction which results in removal of the sulphur from the coal. The coal is then cleaned and separated from the aqueous media, and the inorganic base and elemental sulphur are removed from the aqueous media.

  • Patent number: 4488957
    Abstract: A heavy oil such as an atmospheric pressure residue, a reduced pressure residue of petroleum, etc. is heated to 400.degree. to 500.degree. C. to carry out polycondensation and provide a pitch containing mesophase microspheres. This pitch is once cooled to 200.degree. to 400.degree. C. and a turbulent flow is imparted thereto to cause agglomeration of the mesophase microspheres. The resulting agglomerates are separated to obtain a crystallizable material enriched with quinoline insolubles. Production of the crystallizable material is preferably conducted in a separation tank accommodating the lower part of a heating polycondensation reactor (6) and having a stirring device (12).

  • Patent number: 4488958
    Abstract: Partially purified salt containing less than about 00.4 weight percent insolubles is further purified to reduce the insolubles until the milk pad rating is 3 or better for certain industrial uses and 1 for human consumption. The entry salt is washed in clarified brine to dislodge insoluble impurities adhered to the salt surfaces. The washed salt is then scrubbed with fresh water sprays to displace the wash brine from salt surfaces. The washed salt is drained and then dried in a kiln where flowing air blows away some impurities. The dried salt is passed through a magnetic separator, doubly sifted to remove both large and small impurities, and, where food grade salt is required, passed through a color sorter that removes relatively dark impurities.

  • Patent number: 4488960
    Abstract: The biological reactor contains in a vessel (11) a bundle (13) of tubes (15). The bundle (13) is formed by a plurality of plastic tubes (15) being of preferably square cross-section. The walls of the plastic tubes serve as growth surfaces for microorganisms. A distributing device (17) feeds the different ducts (18) evenly with liquid organic refuse. The ducts (18) are not completely filled. The liquid level in the reactor is at a certain distance from the top of the tubes (15). Accordingly, if one of the ducts (18) tends to clog, it is filled more than the remaining ducts so that in the clogging duct a hydrostatic pressure is created having the tendency to free the duct. This freeing of the duct is assisted by the control unit 58 which from time to time lowers the liquid level in the reactor and then increases it again.

    Abstract: A sewage system is provided for waste disposal units whose waste is removed by the supply of liquid and subsequent application of partial vacuum, for example vacuum closets. In order to make for the employment of large systems, the units are grouped such that a predetermined maximum partial vacuum transport distance is not exceeded. Each such group is connected to a converter in which the partial vacuum is converted into excess pressure which makes for long distance transport, by the intermediary of an intermediate step at atmospheric pressure. Moreover, the waste can be comminuted and oxygenated in the intermediate step of the converter, at the same time as the requisite partial vacuum is established.

    Abstract: A method is disclosed for stabilizing glass which contains nuclear waste by coating the glass with synthetic monazite. The synthetic monazite has a composition of about 30 to about 35% Ce.sub.2 O.sub.3, about 31 to about 36% La.sub.2 O.sub.3, about 27 to about 35% P.sub.2 O.sub.5, and about 2 to about 5% Nd.sub.2 O.sub.3, where the percentage of La.sub.2 O.sub.3 is about 0.5 to about 1.5 percentage points greater than the percentage of Ce.sub.2 O.sub.3. The coating can be applied by detonation gun or by chemical vapor deposition. Chemical vapor deposition can be accomplished by heating halides of La, Ce, Nd, and P or PO and bringing the vapors by carrier gas to the glass where they are contacted by an oxidizing gas such as carbon dioxide, oxygen, steam, or air.

  • Patent number: 4488991
    Abstract: ADP-Ribosylating toxins are rendered enzymatically inactive by reactions with photolabile affinity reagents. The toxoids retain the antigenic and immunogenic properties of the original toxins. These bacterial toxoids can be used as immunogens to protect against the specific disease that the precursor toxins cause or, in the case of P. aeruginosa, the toxoid can be used in combination with E. coli J-5 vaccine to protect against gram-negative bacteremia in general.

  • Patent number: 4488999
    Abstract: In a process for the recovery of cobalt oxalate and/or manganese oxalate, the solutions or extracts containing cobalt and/or manganese are treated with sodium, potassium or ammonium oxalate. To obtain an easily filtrable cobalt and/or manganese oxalate precipitate, the precipitation is performed at temperatures of 50.degree. to 160.degree. C. with 1 to 2 moles of solid alkali oxalate or ammonium oxalate. When sodium oxalate is used, the water content of the solutions or extracts is from 5 to 90% by weight, when potassium oxalate is used it is from 2 to 15% by weight, and when ammonium oxalate is used it is from 1 to 12% by weight.
