Abstract: 1,247,312. Perforating. T. D. WILLIAMSON Inc. 30 Jan., 1970, No. 4694/70. Heading B3W. [Also in Division F2] In the tapping of a coupon from a pipeline 11, a hollow support 13 is located on a threaded stud 10 welded to the pipe in the area to be tapped by means of a disc (12), Fig. 2, not shown, or of a saddle 15, in which a shaped charge (14), Fig. 7, not shown, is mounted in a downwardly open groove (16). The hollow support 13 is welded to the pipe, the saddle, if used as a guide, being removed during the welding. A housing 28 mounted on the support 13 encloses the charge in a fluid-tight space 24, the housing including a gate valve 25 and a fitting 26, a rod 27 passing through the fitting and being screwed to the stud 10. The charge is detonated by a fuse 20, the coupon moving into the pipe by only the distance allowed by a shoulder 34 on the rod 27 screwed to the coupon. The coupon is then withdrawn above the gate valve 25 which is closed to seal the pipe. The fitting 26 can also then be removed. In another method, Fig. 9, the support 35 forms part of a split tee 36. One saddle may carry two or more separate charges.

Abstract: 1,216,707. Homogenizing melts. J. E. OSTBERG. 30 Jan., 1968 [9 Feb., 1967], No. 4791/ 68. Heading B1C. In a method of mixing materials of different specific gravities including at least one liquid phase to promote reaction between them, a turbulent flow is produced by apparatus moving in the liquid with a reaction of rotation or translation while a gas is simultaneously introduced under pressure into the zone of separation of the phases or components. The gas may be inert (e.g. organ) and promote mixing only, or may enter with the reaction (e.g. oxygen or a hydrocarbon); the mixture may comprise a metal melt and the gas be a desulphurizing gas. The apparatus may be that of Specification 956,600 and the gas be fed into the stirrer, or may be a pump, impeller or paddle wheel.

Abstract: 373,162. Heating by electricity. YOUNGSTOWN SHEET & TUBE CO., Stambaugh Building, Youngstown, Ohio, U.S.A.-(Assignees of Adams, J. L. ; 2519, Ohio Avenue, Youngstown, Ohio, U.S.A.) Feb. 17, 1931, No. 5061. Convention date, May 20, 1930. [Class 39 (iii).] A tube is welded by utilizing the work piece as the moving secondary of a transformer and inducing therein a succession of heating currents from primary coils, connected in parallel and arranged in alignment. The tube is fed through similar roll passes 3, 2, and a split frame 25. A laminated voke 28 has polepieces 30, 32 which surround the tube and the primary coil 40 fed by conductors, and arranged as in Fig. 21, is arranged within the tube. The edges of the tube are' brought into contact between the passes 3, 2 to cause a flash. A flash zone is formed along the open seam, and where the edges are in contact a resistance heating zone is formed. By adjusting the rolls of the frame 25 the relative extent of each zone is varied. In Fig. 20, the tube M to be welded is shown in the flash zone. The vaporized metal V acts as a secondary conductor to the internal coil 40 and a magnetic repulsion of the vapour results which cleans the joint. A water jet may cool the metal when it leaves the pass 2. The primary coil 40 is shown in Fig. 21, in which the current from a conductor 50 is fed to coils 49, 48 arranged in alignment and connected in parallel. The flash coil 48 and resistance coil 49 are arranged to impress different voltages on the flash and resistance zones. The coil may be cooled by a watercooled liner provided with lips for spacing it from the tube, Fig. 23 (not shown). An exterior regulating coil may be provided. In a modification, Fig. 8, a core is used inside the coil. A frame 95 carries rolls 118 for regulating the gap of the seam. A laminated yoke 122 terminates in a pole 127 through which the tube travels, and in a wedge-shaped pole 126 at the entry end of the machine. Within this tube is supported a laminated core 132 provided with cooling means surrounded by a watercooled coil 134 fed by leads 138, 148. Surrounding the coil 134 is a non-magnetic cooling jacket. Cooling fluid is supplied to the coil 134 and the jacket by connection 139. A non- magnetic guide surrounds the jacket. A valve 149 for the cooling water supply is connected to a circuit interrupter 151 for the coils to prevent the coils being energized unless the cooling fluid is flowing.

Abstract: 868,678. Nuclear reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 2, 1959 [Feb. 19, 1958], No. 5375/58. Class 39(4). A reactor suitable for marine use has its core in a horizontal cylindrical pressure vessel, mounted so that the supports for the core in the vessel and for the vessel in its surroundings act radially and in line, so that the weight of the core does not cause bending stresses in the vessel; core and vessel are located by keys along their top surfaces. The core 2 and an attached end shield 29 are supported by bearing plates 48 on pads 6 inside the pressure vessel. The pressure vessel rests on pads 5 supported by a support structure through bearing plates 46. Keys 7 on the core and end shield engage keyways 8 inside the pressure vessel. Girders 10 and pads 11 act as keys to locate the pressure vessel in the support structure. The pressure vessel is held down gy straps 53 ; it has thermal insulation 42 and is surrounded by a thermal shield 44 and a biological shield 43. The biological shield rests on rubber pads 58 on a box grid base 54, and is located by keying parts 61 and 63. The end 45 of the biological shield and the end of the pressure vessel are removable to allow removal of the core. Incoming coolant flows between the pressure vessel and the core to cool the supports. The coolant inlet and outlet are coaxial; the outflow is through part-annular channels in the end shield and a doublewalled space 33. Specification 868,677 is referred to.

When mounted transversely of the vehicle, the major axis a of the epitrochoid is inclined above the centre of the epitrochoid by up to 15 degrees in relation to the vertical towards the centre of the vehicle and the spark-plug is located facing outwards of the vehicle adjacent the minor axis b. It may be mounted either at the front or the rear of the vehicle. A bracket 12 formed on the casing which carries the oil reservoir 11 also carries the engine auxiliaries 16, Fig. 3, with the exception of the engine starter. The arrangement permits a decrease in the overall dimensions of the engine, prevents the reserve of lubricant passing into the engine when the vehicle is travelling on gradients and also permits the fitting of a two-shaft gear-box 13 of the kind fitted to reciprocating I.C. engines. The engine may be installed as a multiple unit longitudinally on a vehicle without any alteration as to the positions of the admission and exhaust ducts, the oil reservoir and engine auxiliaries, a second oil reservoir in front of the bracket 12 is however fitted.
