Abstract: 1,257,630. Repairing tubes. BABCOCK & WILCOX Ltd. 10 March, 1969 [8 March, 1968], No. 11687/68. Heading F2P. A faulty upright tube of a ship's boiler is repaired by cutting out the faulty section leaving upper and lower parts la and 1b, welding the end of a tubular insert 3 intended to replace the faulty section into the end of a sleeve 4 in partial overlapping manner, inserting the insert/ sleeve assembly between the tube parts and raising the assembly so that the sleeve 4 overlaps the end of tube part la, and welding the said overlapping sleeve to the tube part la. The lower end of the insert and the upper end of the lower tube part 1b is secured by a second sleeve 5, which is welded at its upper end to the insert and at its lower end to a ring 6, which is itself welded at its inner periphery to the lower tube part 1b. The lower end of the sleeve 5 is chamfered at its external edge to define an extreme end face which has a diameter less than the ring 6 whose diameter is equal to the outer diameter of the sleeve. Thus, the upper surface of the ring projects radially outwardly from the extreme end face of the sleeve and the weld securing the sleeve to the ring is effected between the chamfer and this portion of ring upper surface which projects radially beyond said sleeve end face. The procedure permits all the welds to be effected as " downhand welds," the weld 10 being effected as a downhand weld and the assembly of sleeve 4 and insert 3 being then inverted to the position shown prior to introduction between the tube parts la and 1b. The sleeve 5 may be threaded on to the insert prior to insertion between the tube parts and subsequently slid down into abutment with the ring 6 welded to the lower tube part for welding to said ring. Alternatively, the ring 6 and sleeve may be dropped over the lower tube part before introduction of the insert, the ring and sleeve being slid upwardly into their final position once the insert is positioned.

A coloured photograph or television display of a patient in two different conditions-e.g. the urine passages before and after injection of a contrast agent, or the palate for two different tongue positions-is produced by forming a positive image in one condition and a negative image in the other condition, and forming superposed images in two or three different colours from two or more of the positive image, the negative image, and a combined image derived from the positive and the negative images, whereby, for the examples referred to above, the urine channels are exhibited in a colour different from that of the surrounding tissue, or the two tongue positions are exhibited in different colours. In one method, a developed X-ray film c of the patient is mounted between an illuminator b and a television camera a, the signal from which is employed to control the green signal of a colour television set d, which thereby displays the vertebrae in green. After injection of a contrast agent into the patient, the image formed on a radioscopic screen e is amplified by the image intensifier f, the output from which controls the blue signal of set d to provide a blue display of all tissues surrounding the vertebrae and the urine channels. The image signals from camera a and screen e are also combined, and inverted in inverter 9, the output from which controls the red signal of set d to show the urine channels in red. In a second method, a film A made prior to injection of a contrast agent is copied, by superposition, on to another film to provide a positive B, and a further film C is made subsequent to injection of contrast agent. Films B and C are then superposed on colour photographic paper which is exposed to give a combination image using blue and yellow filters, whereafter films B and C are replaced by film A and the photographic paper is exposed using red and yellow filters. Instead, images A, B and C may be simultaneously projected upon a screen using a lens and prism system and coloured filters. In a further method, film A is copied on to photographic paper in one colour, the B+C combination in a second colour, and the negative of the B+C combination in a third colour.
