Abstract: 855,219. Boring sub-aqueous wells. ZAPATA OFF-SHORE CO. April 9, 1959 [Oct. 27, 1958], No. 11993/59. Class 85. Apparatus for drilling a submerged well comprises a freely floating vessel 10 supporting a derrick 15 on a platform 14 overhanging the side of the vessel, and a support structure 20 mounted on the water bottom over the site of the well. The support structure 20 comprises a tripod with one vertical leg 25 and two inclined legs 26, 27 and is fixed in position by a pile driven through each leg. The pile through the vertical leg forms the top-most section of the well-casing and projects above the surface of the water. The derrick supports an I-section beam 17 which forms a guide for a trolley 8 which is attached to a travelling block 18. Suspended from the block is an hydraulicallyoperated power swivel 19 which is also guided from the I-beam 17 by arms 57 and rollers 58. The drive shaft 62 of the swivel is screwed on to the drill string 63 which includes a sub. in operation the rolling motion of the vessel is accommodated by the movement permitted by the free fit of the rollers 54 and 58 in the beam and by the flexibility of the drill string. Fig. 7 shows a view of the conditions after an exaggerated amount of roll has occurred. Vertical movement of the vessel is taken up by the sub in the drill string which, since it is mounted a constant distance above the drill-bit ensures a constant cutting pressure.

Title: Improvements relating to the manufacture of butted tubes
Inventor: MORRIS FREDERICK WILLIAM
IPC: B21C37/16
Filed: 1958-04-17
Abstract: 854,534. Drawing; separating mandrels from work; tube expanders. REYNOLDS T. I. ALUMINIUM Ltd. April 7, 1959 [April 17, 1958], No. 12262/58. Classes 83 (2) and 83 (4). In a method of making butted tubes, i.e. tubes with local thickening, a tube 11, Fig. 1, is first passed together with a mandrel 12 having end-portions 12a of reduced diameter, through a die 15 so that the tube wall conforms to the shape of the mandrel, the tube then being loosened by pinch rolls 16 prior to stripping from the mandrel by arresting the movement of either the mandrel or the tube. The tube 11 is pulled through the die 15 by jaws 14, the tube being stripped after completely passing the die by the continued movement of the jaws 14 while the mandrel 12 is held stationary by the engagement of a head 13 with the die, Fig. 3. The stripping movement causes the intermediate part of the mandrel to expand the thickened trailing end of the tube so that a butted tube, as shown in Fig. 5, is produced. If internal thickening is required at both ends, the tube of Fig. 5 is passed while unsupported internally through a die of similar diameter to that of the die 15. If external thickening is required at both ends the leading end of the tube is expanded by a plug 18 while held against an abutment 19, Fig. 8 (not shown). Local thickening may also be provided intermediate the ends of the tube in a similar manner using an intermediate reduced mandrel portion 12c, Fig. 9 (not shown). In a modification the tube and mandrel may be pushed through the die, the mandrel being stripped by retrogressive movement, while the tube is held stationary by a U-shaped member which is introduced over the mandrel and which bears against the die or diecasting.

Title: Nozzles for molten metals
IPC: B22D41/58
Filed: 1972-07-27
Abstract: 1379236 Pouring molten metals ARE SINGER 27 July 1972 [29 April 1971] 12291/71 Heading F4B The erosion of pouring nozzles for molten metals is reduced, and the flow of metal through the nozzles is controlled by producing a film of gas between the surface of the metal and of the nozzle while the metal is being poured. Inert gas, such as nitrogen or argon is fed under pressure to a jacket 1 surrounding a nozzle 2 formed of a porous refractory material secured to a ladle 3. The nozzle 2 may be formed by compacting and sintering powder or granules of magnesium, alumina, silicon nitride or silicon carbide bonded with silica nitride so that the nozzle remains porous. The flow may be controlled by a stopper rod 6, or, in small diameter nozzles, it may be controlled by altering the pressure of the gas supply. The gas supply to different parts of a nozzle may be different, so that the width of a ribbon of molten metal from a slot nozzle may be controlled. Liquids which volatilize or decompose at the temperature of the molten stream may be fed to a water cooled nozzle. Channels formed at the outer surface of the refractory nozzle distribute the liquid, which may be paraffin, water or a halogenated or other hydrocarbon, round the nozzle. The liquid may be supplied to the nozzle from a tank under hydrostatic pressure or may be pumped to the nozzle. Gases or vapours such as air, mixtures of carbon monoxide and carbon dioxide or steam may be fed to the nozzle according to the permissible amount of reaction with the metal. The nozzle may have holes or slots to increase the supply of fluid.

Title: Improvements in the purification of cracking gases
IPC: B01D47/06
Filed: 1957-04-16
Abstract: <PICT:0809888/IV (b)/1> The gases formed in the production of acetylene by cracking hydrocarbons in the liquid phase are purified by using the hydrocarbons to be cracked, before their entry into the cracking plant, for the separation of carbon black, hydrocarbon mist and unsaturated polymerizable compounds, especially higher acetylenes, from the cracking gas, in a washing stage provided with one or more wet purifiers.  In an example, a crude gas oil of boiling range 150-400 DEG  C. is cracked in an apparatus shown as vessel 1. The gases leave at 150 DEG  C. and pass to the first wet purifier 2 which is a liquidactuated blower which is charged through pipe 14 with hydrocarbon to be cracked, the gas is cooled to 50 DEG  C. and much of the carbon black and hydrocarbon mist is removed.  In the cyclone separator 3, the cracking gas is freed from the greater part of the atomized washing liquid which flows through the dip 15 into the sump of the washing tower 5.  The gas is cooled to 30 DEG  C. in a second wet purifier 4 which is constructed as a venturi washer and to which the hydrocarbon to be cracked is applied as washing liquid through pipe 16.  Further hydrocarbon to be cracked is added to washing tower 5 through pipe 17, and the gas then passes through pipe 21 to washing tower 7, more hydrocarbon being added through a pipe 23.  The washing oil, laden with light oil is supplied by pump 12 through the heat exchanger 8 and the heater 9 at a temperature of 180 DEG  C. to the stripper column 10.  The hydrocarbon freed from light oil is conveyed through pump 13, heat exchanger 8 and pipe 19 and finally through pipe 20 to the cracking plant.  Specification 792,604 is referred to.

Title: Electrical energy converter
IPC: H02M7/48
Filed: 1967-03-16
Abstract: 1,109,779. Converting systems. COMPAGNIE GENERALE D'ELECTRICITE. 16 March, 1967 [29 March, 1966], No. 12395/67. Heading H2F. In a system for conversion between A.C. and D.C., e.g. in an H.V.D.C. transmission system, the conversion circuit comprises fullwave rectifier thyristors 28, 30 (Fig. 3) in series with inductances 24, 25 (which may be the leakage induction of the transformer 3), the D.C. being taken off from the centre-tap 21 of the transformer via a series LC circuit 26, 27 shunted by a third thyristor 29; the thyristors are fired from a control unit 11 which receives signals ab representing the A.C. voltage (Fig. 1, not shown), signals cd representing the A.C. current from a current transformer 9, signals AB representing the D.C. voltage and signals BC representing the D.C. current, in addition to signals P from a programming unit. In operation, the actual A.C. voltage is compared in unit 11 with a reference voltage synthesized from the input data, and when the instantaneous value of the former drops below that of the latter a pulse is generated to fire thyristor 28 or 30 (depending on which half-cycle is being monitored). A series resonant circuit comprising capacitor 26 and inductances 27 and 24 (or 25) is then excited (e.g. at 2 kc/s.). and provides one half-cycle, after which time the thyristor 28 (or 30) is cut off. A pulse is then emitted on line q to turn on thyristor 29, the resonant circuit of 26 and. 27 then executes a half-cycle at a higher frequency (e.g. 50 kc/s.). The voltage across terminals 31, 32 thus comprises pulses of half-cycles of the 2 kc/s. oscillation, the durations of the pulses being the durations when the instantaneous value of the A.C. voltage at 1, 2 falls below the reference waveform (see Fig. 2, not shown). This voltage is smoothed at 7 and passed to the D.C. network 10. The current supplied by the A.C. network 1, 2 is thus always in phase with the voltage at 1, 2. A filter 2 is provided to keep the high-frequency oscillations out of the A.C. network. For a three-phase system a circuit as in Fig: 3 is provided for each phase (Fig. 5, not shown). For operation as an inverter the control unit 11 provides a reference current in opposition to the current in the A.C. network, and the reference voltage is that across the A.C. network. For a free-running inverter (Fig. 6, not shown), an auxiliary A.C. source (12) is provided as reference; this may be a separate oscillator.

Convention date, April 22, 1929. [Class 72.] Thin gauge sheet or strip steel having a carbon content not in excess of À35 per cent is passed through a heating zone to heat it above the upper critical range; it is then cooled quickly and sufficiently to arrest grain growth whereupon the cooling is continued in a cooling zone for a time not less than 1À33 times the heating period so as to produce a partially laminated pearlitic structure in a matrix of ferrite. A furnace such as described in Specification 320,841 may be employed comprising a heating zone 2 and a lower-roofed cooling zone 3 having one or more baffles 4 to deflect combustion products about the steel. As an example steel sheets with a carbon content of À08- À1 per cent and piled 2, 3 or 4 high according to thickness are heated to about 1650‹ F. and moved through the furnace at about 11-13 ft. per minute, the heating and cooling zones being about 50 and 100 ft. long respectively. A rapid drop in temperature to about 1500-1550‹ F. ensues at the entrance to the cooling zone in which the steel is gradually cooled to about 800-900‹ F.
