Patent GB-856377-A (GB)
Title: Detergent composition
Inventor: STEVENSON DAVID GORDON
IPC: C11D3/20
Filed: 1958-03-31
Abstract: A detergent composition, suitable for removing radioactive contaminations, comprises (a) a synthetic surface active agent, suitably an alkyl sulphate, (b) a water soluble polycarboxylic acid containing the group -N(CH2COOH)2, preferably ethylenediamine tetracetic acid or nitrilotriacetic acid ("ammonia triacetic acid"), (c) a water soluble nitrogen free polycarboxylic acid, such as oxalic, or more preferably citric, acid, and (d) an alkali metal or ammonium base, for example sodium hydroxide or carbonate, in an amount such that a buffer system is set up whereby an aqueous solution of the composition has a pH of 3-9.  Usually a substance (e) which liberates fluoride ions in solution is also included, for example sodium fluoride.  The composition may be produced in powder form by dissolving ingredients (a) to (d) in a little water at 50 DEG C., adding anhydrous sodium sulphate, and allowing the mixture to cool with stirring.  A cream may be produced from a solution of the resulting powder by the addition of sodium alginate which may be wetted with methylated spirit.  A scouring paste may be produced from such a cream by the incorporation of pumice powder and a liquid glyceride or, more suitably, glycerol.

The die 4 may be of cruciform shape, the limbs 4b being used to receive adjacent interconnected links of a length of chain and the limbs 4a performing the flash-removing operation, the walls of the limbs being inclined from 8 to 12 degrees, and a clearance of from <1>/32 to <1>/64 inch being provided between the walls of the finislied link and the wall of the die. The welded link 6, 7, preferably before it cools down to room temperature after welding, is placed in the die with the flash 8 resting on the edge of the aperture and the outer flash removed by forcing the link into the die by a concaved plunger 3, the stroke of which is limited so that in the final position of the link a clearance x exists between the upper face of the die and the top of the link eye equal to the diameter of one side or end of the link to avoid damage to an interconnected link. In order that the inner flash may be removed at the same time, a tool 10 with a stepped end fitting the non-stripping portion of the die and formed with inclined cutting edges, is placed under the flash inside the eye prior to operating the plunger. The tool may be inserted and removed by hand or automatically.
