Abstract: The invention relates to a method for production of castings of aluminium or its alloys comprising integrated runners intended for the distribution of a lubricant or for the circulation of a heat-exchange fluid. 
<??>The method is characterised in that: 
 
  - one or more previously shaped tubes of aluminium or aluminium alloys are placed in a mould, the ends of the tube or tubes being outside the mould or the cores inserted therein; 
  - the alloy is poured into the cavity of the mould; 
  - after removal from the mould, the excess parts of the tube or tubes are removed. 
 
<??>This method applies to the mass-production of castings having a system of internal runners, such as cylinder heads, compressor cylinders, lubrication systems, convectors, etc.

Title: Hydantoin-enhanced halogen efficacy in pulp and paper applications
Inventor: SWEENY PHILIP GERDON
IPC: D21H21/04
Filed: 1995-10-13
Granted: 2001-07-19
Abstract: Free halogen sources (e.g., sodium hypochlorite and chlorine) added as slimicides in high organic component process streams such as pulp and paper processing are rendered more efficacious by the addition of selected N-hydrogen compounds (namely, 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin, cyanuric acid, succinimide, urea, 4,4-dimethyl-2-oxazolidinone, and glycouril) to the process stream. The latter compounds may be added to the process stream before or after the slimicide is added or combined with the slimicide and added directly thereto. The direct use of halogenated hydantoins has also been found to provide improved efficacy relative to free halogen sources. In addition, absorbable organic halogen by-products are reduced.
