Title: Improvements in or relating to the preparation of an oxygen-free fraction from a crude gaseous mixture containing oxygen
Inventor: SCHUFTAN PAUL MAURICE
IPC: F25J3/04
Filed: 1952-07-24
Abstract: A method for the preparation of a substantially oxygen-free fraction, i.e. not exceeding 20 vols., oxygen per million, from a crude gaseous mixture containing oxygen comprises mixing therewith an amount of hydrogen in excess of that stoichiometrically required to react with the oxygen present, passing the gas mixture so formed over a catalyst adapted to promote the reaction of hydrogen and oxygen to form water and a substantially oxygen-free gaseous product, removing the water formed and partially liquefying the oxygen-free gaseous product to separate a liquid fraction which is substantially free from hydrogen or oxygen, and a gaseous residue containing substantially the whole of the remaining hydrogen.  The method may be used for preparing oxygen-free <PICT:0723050/III/1> nitrogen, argon, krypton, neon, or xenon or argon-nitrogen mixtures, or oxygen and nitrogen-free argon from a ternary mixture of these gases.  Crude argon containing 1 per cent air enters compressor 1 through line 2 after admixture of a gas containing hydrogen and argon in equal proportions.  After compression to say 2.7 atms., the gas passes to catalytic deoxidizer 5, containing, e.g. a supported palladium catalyst, and resulting water is removed in drier 7.  The dried gases pass through heat exchanger 9 and cooler 11 to condenser-evaporator 13 of rectification column 14, where they are completely liquefied apart from a small residue of hydrogen, which passes, with some argon and nitrogen through 15 to heat exchanger 16 where most of the argon and all the nitrogen is condensed and returned to condenser 13 through 17.  The liquid argon from 13 still containing some nitrogen and traces of hydrogen is passed through pipe 18 to upper section of column 14 where the nitrogen and hydrogen are eliminated and pass out through 20 in a gas comprising argon and nitrogen mixture.  The reflux in column 14 is provided by expanding pure liquid argon from the bottom of column 14 through pipe 23 and valve 24 to heat exchanger 16 to cool the hydrogen vent gases, and thence to column condenser 21 through 25.  Pure argon vaporized from 21 is withdrawn through 26 and heat exchanger 9, to cool incoming gas, and is recovered at 27.  The hydrogen vent gases leaving exchanger 16 pass through pipe 29, where pure hydrogen is added through pipe 33 and flow meter 35, the addition being automatically controlled to ensure that the recycle gas passing out through catharometer 31 and flowmeter 32 to recycle line 3 contains hydrogen and argon in approximately equal proportions.  Provided valve 30 is set to give a reading on meter 32 which is more than double that on meter 35 then some hydrogen must be present in the vent gases from exchanger 16 and an excess of hydrogen is maintained.  The hydrogen addition should be controlled to maintain the hydrogen content at the upper limit fixed by the condensing pressure and condenser temperature.

Filed: 1965-05-06
Abstract: 1,087,643. Furnace seals. ELECTRIC FURNACE CO. May 6, 1965, No. 19142/65. Heading F4B. The inlet or outlet of a furnace for the heat treatment of metal strip is sealed by a housing surrounding the opening and a pair of seal rolls 20, 22 engaging the metal strip W and mounted in the side plates 12 of the housing so that one roll can be moved away from or towards the strip W, sealing means between the ends of the rolls and the housing and sealing plates 66 to seal the roll peripheries to the housing being provided. Each roll 20, 22 has an outer covering 28 of heat resistant resilient material and is mounted in bearings secured to crank arms 44, 46 so that the roller shafts project through arcuate slots in the side-plates 12 of the housing. The cranks 44, 46 are pivoted to the side plates 12 and operated by fluid cylinders 52. Toothed sectors 54, 56 enable the rolls 20, 22 to be operated by a single cylinder. Torsion bars 50, 64 preserve the rolls in a parallel position, the thinner bar 64 enabling greater pressure to be put on one end of the rolls to correct any deviation of the strip from its proper track. Nut and bolt operated slides 186, 187 close the furnace above the rolls to enable adjustments and repairs to be made without loss of furnace atmosphere. Sealing plates 66 secured to housing members 14 are faced with felt. In another embodiment, the cranks carrying the rolls are connected together so that the rolls are moved together by a single cylinder at each end. In a furnace through which the strip follows a horizontal path, only the upper roll moves, and a single slide seals the furnace to allow for repairs to the rolls. The hydraulic system for operating the rolls includes throttle valves in the inlet lines to control the speed of operation and regulators to adjust the pressure applied at each end of the rolls. The throttle valves and regulators are by-passed by one-way valves so that the speed of operation can be separately adjusted for retracting the rolls and for applying them to the strip.

Title: Improvements in electric power transmission
IPC: H02J3/04
Filed: 1929-06-22
Abstract: 337,022. Taylor, A. M. June 22, 1929. Drawings to Specification. Transmission conductor arrangements; systems depending on static transformers.-In a threephase system in which the transmission of power is effected by four single conductor cables on a four-phase circuit, the transformer windings at each end of the line being three-phase on one side and on the other side arranged in two quarter-phase groups, double bus-bar three-phase oil circuit-breakers (i.e. a combination of threephase switch and three double throw selector switches in series, one on each pole) are arranged in association with two spare cables and a solidly connected neutral so that a spare cable may replace a faulty one, the load being carried by one quarter-phase group during substitution. The connections are changed after the faulty cable and its fellow have been de-energized by simul. taneous opening on fault of the circuit-breakers at each end of the line. The arrangement permits either spare cable to be connected to either of the two transformer windings constituting a quarter-phase pair and the two spare cables to replace either pair of working cables, these being laid in the ground so as to be magnetically balanced. Spare transformers equivalent to one quarter-phase system may also be provided, and switching arrangements are provided whereby the windings thereof may be so connected as to replace those of either quarter-phase. The switches used with the transformers may be oil immersed and of drum type, interlocked with the oil circuit breakers. Switching operations are synchronized at both ends of the line, and the isolating or selector switches are interlocked with the oil switches. Double bus-bar oil circuit-breakers with two bridge-pieces per phase operating alternatively may be employed in place of the type above-mentioned. Specifications 317,099; and 327,799, [Class 38 (v), Electric switches &c.], are referred to.

Title: Improvements in or relating to ball joints and method of manufacturing the same
IPC: F16C11/06
Filed: 1938-06-29
Abstract: 516,591. Connecting-rods. ASKANIA-WERKE AKT.-GES. June 29, 1938, Nos. 19364 and 19365. Convention dates, June 29, 1937 and Nov. 6, 1937. [Class 122 (i)] [Also in Groups XXV and XXII] A ball joint,in which the socket surrounds more than half the ball, is formed by taking a hollow workpiece 5, Fig. 4, provided with an external annular bead or collar 12, inserting the ball 2 in the workpiece and then upsetting or swaging the metal of the collar so that the inner surface of the workpiece 16 follows the external contour of the ball. The collar 12 may contain an excess of metal 12a after the ball seat has been formed which when acted upon by a swaging tool 13 causes the rim 11 to be forced away from the ball. The one-piece piston and ball cup 4, Fig. 2, may be formed in a similar manner by using a workpiece having a tubular extension which forms the skirt of the piston. The pistons may also be formed from a workpiece 101, Fig. 7, having collars 2<1>, 3<1>, between which the balls 3 of the connecting rods are placed. Tubular tools 13 force the collars 2<1>, 3<1>, inwardly so that they take the shape shown, in Fig. 8, and the balls 3 are trapped between a pair of seatings 124, 125. Collars 116 prevent the piston rods k being drawn in during the formation of the seat 124. The two collars 3<1>, may be combined in a single collar. After withdrawal of the swaging tools 13 the outside of the pistons may be turned and the. two separated along the line X-Y. The balls and piston rods may be formed of nitro-steel and the cups, of unhardened beryllium bronze which may be hardened after the swaging operation. Ball joints made according to the invention are particularly suitable for joining connecting rods and pistons for hydraulic piston gear, as the diameter of the ball may be made 75 to 85 per cent. of the external diameter of the piston so that the load indirectly transmitted to the connecting rod is small. The construction also allows the driving ball 2, Fig. 2, to be of a larger diameter than the piston so that a pressure relieving groove 7, in communication by passages 20, 21 with the pressure at the head of the piston, may be given a diameter substantially equal to that of the piston 4.
