Abstract: 369,153. Uniting by fusion. PINTSCH AKT.-GES., J., 71, Andreasstrasse, Berlin. Oct. 1, 1931, No. 27367. Convention date, Nov. 28, 1930. [Class 83 (iv).] In welding large articles the welding head is moved vertically by a guide column and horizontally by a travelling crane and trolley. In order to effect also circular welds or welds on spacial curves the work is carried by a rotating table 2, which is rotated by a motor 1 through cable transmission so as to avoid lost motion. The arc welding head is carried by a column 6 slidable in a guide 8 on a trolley 7 traversable by a cable transmission on the bridge 9<1> of a portable crane. The cable is provided at its ends with balance weights 21, 21<1> and passes over rollers 20, 20<1>, 19, 19<1> on the bridge, rollers 15 .. 18 on the trolley, and a roller 23 on the column 6. The rollers 15, 16 are driven in opposite directions through magnetic clutches 13, 14, intermediate gear 12, and a liquid gear 11 from a motor 10. Clutches 22, 22<1> are also provided to fix the rollers 19, 19<1> to the bridge when desired. To raise the column either the roller 19 is clamped to the bridge and the roller 15 rotated or both clamps are released and both rollers 15, 16 driven. The head is lowered by reversing the motor. To effect a horizontal motion of the trolley both clutches 22, 22<1> are put in operation and either of the rollers 15, 16 driven. The current is supplied to the welding head by sliding contacts on the guide column and the motor and clutches may be switched on or off from a platform on the head.

Title: Improvements in or relating to magnetic deflecting means for cathode ray tubes
Inventor: BULL ERIC WILLIAM
IPC: H01J29/76
Filed: 1951-11-24
Abstract: 729,918. Cathode-ray tubes. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 16, 1952 [Nov. 24, 1951; April 9, 1952; May 22, 1952; June 26, 1952], Nos. 27597/51, 9008/52, 12928/52 and 16049/52. Class 39 (1). Additional compensating coils are associated with the main deflecting coils of a cathode-ray tube and suitably energized to set up a compensating magnetic field which reduces the waste magnetic field produced outside the magnetic yoke by the main deflecting coils. In Fig. 2, the auxiliary coils 25, 28 embrace the end limbs 21, 22 of the yoke 18 which screens them from the air space. The deflecting coils 23, 24 are connected in series with the auxiliary coils to give opposed fields but parallel connections of both sets of coils are referred to. In a modification (Fig. 3, not shown), the compensating coils are of the saddle type with active sections extending round the deflecting coils and idle sections following the yoke contour. Fig. 9 shows closely-fitting saddle-type compensating coils 62, 63 on a square yoke and surrounded by a two-part magnetic screen 64, 65. The effect of the compensating windings may be adjusted by including variable resistance means in the closed circuit. The latter may be energized by the transformer action of the coupling between the deflector coils and the compensating coils. A coil in the closed circuit may have its inductance varied by means of a movable magnetic core, and so adjust the amplitude and direction of the deflecting field; and a further variable coil in series with the deflecting coils maintains the impedance of the circuit constant (Figs. 10 and 11, not shown). The non-linearity of the scanning may be additionally compensated by including in the circuit of the flux compensating coils a variable circuit element having a non-linear current/voltage characteristic, e.g. a metal rectifier or a saturable inductance in series or parallel with a fixed or variable linear resistance. The magnetic yoke may be closed rectangular or circular, or an open yoke with polepieces defining the air space for the cathode-ray tube. Specification 612,906 is referred to.

Filed: 1936-10-13
Abstract: 485,089. Electrolytic treatment of metals. LANG, H. M. Oct. 13, 1936, No. 27822. Convention date, Oct. 14, 1935. [Class 41] Continuous conversion or corrosion, particularly solution of a metal anode is effected by alternating current by the use of a rectifying cathode. The process is particularly applicable to the refining of gold. In the gold refilling apparatus shown, cathodes 5, 6 of tantalum are connected across a transformer 14, the anode 1 being connected to the mid-point so as to provide whole - wave rectification. The cathodes are enclosed in porcelain containers 7, 8 to prevent deposition of metal thereon. The anolyte consists of 15-25 per cent hydrochloric acid together with a small amount of an oxidizing agent such as sodium nitrate or nitric acid and the catholyte consists of 36 per cent hydrochloric acid. The cathodes are tubular for the passage of a cooling medium. By the adjustment of resistances 19, 20 an alternating current may be superimposed on the direct current passing through the electrolyte. A resistance 17 may be inserted in the anode lead. By means of a tapping 18 direct current may be drawn off for operating another cell. The electrolyte may alternatively consist of alkali metal cyanide solution. When aluminium cathodes are employed, the catholyte may consist of sodium tetraborate solution with or without addition of boric acid. After electrolysis silver chloride in suspension is removed by settling, and gold is precipitated therefrom by a reducing agent such as sodium bisulphite and washed.

Patent GB-826297-A (GB)
Title: Process for purifying hydrocarbons
IPC: C10G53/12
Filed: 1957-09-10
Abstract: A process for purifying hydrocarbon oils containing moisture and sulphur compounds as impurities comprises the steps of (i) vaporizing the oil; (ii) removing substantially the entire moisture content of the vapour; (iii) contacting the vapour with a molten alkali metal supported on a solid particulate carrier, thereby converting the sulphur compounds to a separable form; and (iv) recovering a purified oil.  The moisture may be removed by means of a selective inorganic adsorbent, a 4 to 5A DEG  molecular sieve adsorbent being particularly suitable when the oil consists of aromatic hydrocarbons contaminated with aliphatics and moisture, e.g. oil delivered from coke oven gas or the distillation of coal tar.  When the oils are non-aromatic silica gel may be used to adsorb the moisture.  The temperature of the oil vapour may be 160 to 250 DEG  C.  Alkali metals mentioned are sodium, lithium, potassium, rubidium and c sium. Sodium, potassium or lithium carbonate may be used as the carrier. Contact between the oil vapour and the alkali metal may be effected cocurrently or in countercurrent or as a fixed or fluidized bed. Suitable contact times are 3 to 6 seconds.  In an example aromatic hydrocarbons are recovered from coal tar light oil by vaporizing the oil at 170 DEG  C., contacting the vapour with a 5A DEG  molecular sieve (a synthetic zeolite), and then heating the vapour to 235 DEG C. and contacting it with molten sodium deposited on 10 to 30 mesh sodium carbonate (U.S. sieve) for six seconds.ALSO:A process for purifying aromatic hydrocarbons containing moisture and sulphur compounds as impurities comprises the steps of (i) vaporizing the oil; (ii) removing substantially the entire moisture content of the vapour; (iii) contacting the vapour with a molten alkali metal supported on a solid particulate carrier, thereby converting the sulphur compounds to a separable form; and (iv) recovering a purified oil.
