Patent GB-2027451-A (GB)
Title: Electrolytic apparatus for producing foam
IPC: B03D1/14
Filed: 1978-08-08
Abstract: Foam is produced electrolytically in a liquid having foaming tendencies through the use of closely spaced electrodes 42, 50 of opposite polarity that are disposed in substantially upright dispositions within the body of liquid being treated. The electrodes extend from a position deep within the body to a point at or above the surface 36 of the body, and the electrodes are so formed or are associated with such other structure that bubbles generated within the columnar treating region between the electrodes cannot escape from the electrodes until reaching the surface of the liquid, thereby being confined and exposed to the electrodes throughout the full extent of travel by the bubbles to the surface. By regulating the position of the bubble outlet relative to the surface of the liquid, the characteristics of the foam produced from the bubble discharge may be varied. <IMAGE>

Title: Process and apparatus for use in the production of refuse derived fuel
IPC: C10L5/46
Filed: 1981-03-24
Abstract: The combustible portion of refuse is compacted and dried as fuel. A particular embodiment comprises taking raw refuse, pulverising it and then screening it to remove fines and oversize material, the screened residue being passed to an air classifier where the light fraction, rich in paper and plastics, is separated. This light combustible refuse fraction is then passed to a densifying machine, either directly or via a secondary shredder, to produce partially compacted material which is then dried in a rotary dryer. The dried material can be passed to a second densifying machine which produces pellets in the form of small dense cylinders or blocks having a calorific value equal to about half that of coal. Coal dust or other combustible particulate material can be added to and mixed with the combustible fraction between the two densifying machines.
