Title: Improvements in or relating to removal of metal contaminants from residual oils
IPC: C10G21/00
Filed: 1955-03-30
Abstract: Petroleum fractions containing a major proportion of components boiling above 900 DEG  F. are freed from metal contaminants, for example nickel, vanadium and iron, by contacting with a liquefied normally gaseous hydrocarbon, washing the fractions with a synthetic asphalt, and separating the oil phase from the asphalt phase containing the metal contaminants. Fractions referred to are residual petroleum fractions and gas oil.  Hydrocarbons specified are ethane, propane, butane, propylene and butylene; a mixture of 30 per cent butane and 70 per cent propane is referred to.  The process may be carried out at 100-300 DEG  F.  The synthetic asphalt is produced by thermally cracking cycle oil obtained in the catalytic cracking of gas oil. The products of the thermal cracking are preferably treated to remove gas oil, for example by distillation or by treatment with a liquefied normally gaseous hydrocarbon.  The treated crude oil may be catalytically cracked, for example, together with gas oil distilled from the crude oil before treatment.  The residue from the catalytic cracking process may be used to prepare the synthetic asphalt.

Title: Improved wire clothes peg
IPC: D06F55/00
Filed: 1945-04-19
Abstract: 581,678. Wire clothes pegs. PEARSON, G. W. J. April 19, 1945, No. 9878. Convention date, July 31, 1941. [Class 44] A clothes peg is formed from a single length of wire, bent so that it mainly forms a triangular figure with spring circles at the base angles. At one end of the wire an eye 10 is formed, then the wire is bent to form a U. The opposite leg to the one containing the eye 10 is passed through this eye, and then forms a circle 12 which again passes through the eye. The wire passes tangentially from the circle and diagonally from the U in a substantially straight line 13 to form another circle 14. From here it passes tangentially in a substantially straight line 15 diagonally towards and through the U. It is then bent to form two oppositely-positioned V's 16, 17 which normally lie between the members of the U. At the extremity of the wire an eye 11 is formed, and this engages with the bottom of the U on the side opposite to the triangular part of the peg. The bottom of the U is bent inwardly towards the triangle. The circles cause the eye to press strongly against the U, but pressure applied at the points 18, 19 will make the jaws, i.e. the V and the U-shaped bends of the peg open. In use a portion of the fabric is bent across the clothes line, and both fabric and line are passed through the open jaws of the peg until they lie in the V 16 ; when pressure is removed the jaws automatically return to their normal positions and the fabric is firmly held.
