Title: Production of useful articles from coal
Inventor: BENNETT JOHN GODOLPHIN
IPC: H01R43/12
Filed: 1947-10-27
Abstract: Poorly agglutinating coal of a swelling number less than 4, having a volatile matter content between 10 and 13 per cent, and subdivided so that about 95 per cent will pass a 200-mesh B.S. sieve, is moulded under pressure to form the shape of the desired article, e.g. a commutator brush, heated under non-oxidizing conditions to at least 550 DEG  C. and preferably at least 700 DEG  C. at a rate of not less than 2 DEG  C. per minute, and then cooled under non-oxidizing conditions.  The product is of a comparatively coarse structure with harder particles embedded in a softer matrix.  Commutator brushes made in this way have a burnishing effect on the commutator.  A proportion, e.g. 10-20 per cent, of a coking coal may be mixed with the poorly agglutinating coal. The heating may be carried out in an atmosphere of ethylene or other readily decomposable hydrocarbon, to reduce porosity.  In an example a South Wales carbonaceous coal (3.7 per cent ash and 12.8 per cent volatile matter) was ground to pass 95 per cent through a 200 mesh sieve, and 90 parts of this mixed with 10 per cent strongly coking coal ground to the same size.  Bars measuring 2 1/2 X\ba1/2 X\ba1/2 inches were moulded from the mixture at 8 tons pressure per square inch, placed in powdered coke in a steel box and heated to 1000 DEG  C. at 25 DEG  C. rise per minute, the high temperature being maintained for 1/2 hour. An atmosphere of nitrogen was maintained in the furnace and after cooling to 200 DEG C. the box was removed from the mould. Specifications 595,759, 595,760, 595,761 and 595,763 are referred to.
