Patent GB-946246-A (GB)
Title: Improvements in or relating to a process for the production of tubular carbon articles
Inventor: WALTERLOSTY HOWARD HAROLD
IPC: C04B35/524
Filed: 1960-09-30
Abstract: Tubular carbon bodies are made by heating to carbonization a tube of regenerated cellulosic or hemicellulosic material supported on a mandrel of smaller cross-section than the interior of the tube but sufficiently large to engage with the tube as a result of shrinkage during the carbonization step, the configuration of the mandrel corresponding to the desired internal configuration of the tube and the coefficient of thermal expansion of the mandrel being greater than that of the tube at or near the temperature at which the tube is carbonized.  In an example, a comminuted hemicellulosic pulp was centrifuged and the pulp extracted in the form of a soft wet tube, the mandrel, e.g. of wood or steel, inserted and dried for 48 hours at 70 DEG  C. It was then placed on a steel mandrel in a pressure vessel and heated in an atmosphere of N2 to 350-450 DEG  C. for 48 hours.  The pressure was reduced at 300 p.s.i. per 1/4 hour to atmospheric pressure and the material carbonized on its mandrel at 750-800 DEG  C. in a vacuum furnace.  The mandrel was removed and the body heated to 1500-2000 DEG  C. to graphitize. The dried tube may be machined to size prior to carbonizing and different mandrels may be used for different heat treatments. In a modification the mandrel used during the carbonization may be a ceramic fuel for a nuclear reactor, e.g. U2O3 or U.  The tubes produced are used as cans for fertile or fissile material for reactors. Specifications 860,342 and 889,351 are referred to.

Abstract: 777,369. Treating polluted liquids. DORROLIVER, Inc., [formerly DORR CO.]. Nov. 23, 1954 [Nov. 30, 1953], No. 33876/54. Class 111. In treating polluted liquids such as sewage containing grit as well as other suspended solids the customary prior de-gritting treatment is omitted : instead, all solids are settled together, and the grit is subsequently separated from the sludge thus obtained. Raw sewage flows along conduit 10 into a settling tank 14, the sludge from which passes at 28 to a grit separator 34. Grit moved up the inclined deck 36 of the latter by a reciprocating rake 46 is washed by liquid introduced at 48 before discharge from the upper end. Diluent liquid preferably containing dissolved oxygen may be introduced at 52 where the concentration of the incoming sludge is too high for grit to separate from it. Dilute sludge overflowing at 42 passes at 44 to a thickener 56 incorporating a rotating " picket fence " structure 68. Supernatant from the thickener, and also from a digester 76 to which the thickened sludge is conveyed, are returned to the incoming sewage. A detailed description is provided, Figs. 2 and 3 (not shown), of a combined grit-separator (34) and thickener (56).
