Title: Recovery of copper and vanadium from aqueous streams by ion-exchange
IPC: C07C51/31
Filed: 1961-09-25
Abstract: Vanadium and copper values are recovered from aqueous solutions containing them, especially from the acid liquors obtained from the nitric acid oxidation of cyclohexanol and cyclohexanone to adipic acid, by using a cation exchange resin at a pH value of - 0.3 to 1.8; the vanadium being present as vanadyl ions and the copper as cupric ions are absorbed by the exchange resin which is subsequently eluted with a solution of a strong mineral acid. A temperature range of 33-90 DEG  C. is preferably used and vanadium in solution in 0.05-1.5% by weight calculated as ammonium vanadate and copper 0.16-5.0% by weight. Nitric acid present is not more than 20%. No extraneous material is added during the recovery and this facilitates recycling of the solution.  The cation exchange material is an oxidation resistant, water insoluble polymer especially a sulphonated polyvinyl aryl compound cross-linked with a divinyl aryl compound.ALSO:Catalytic vanadium and copper values are recovered from the acid liquors obtained from the nitric acid oxidation of cyclohexanol and cyclohexanone to adipic acid, by using a cation exchange resin at a pH value of -0,3-1,8; the vanadium being present as vanadyl ions and the copper as cupric ions are absorbed by the exchange resin which is subsequently eluted with a solution of a strong mineral acid.

Title: Improvements in or relating to television time bases and like apparatus
IPC: H04N5/10
Filed: 1938-11-25
Abstract: 521,814. Television. KOLSTER-BRANDES, Ltd., and BEATTY, W. A. Nov. 25, 1938, No. 34356. [Class 40 (iii)] The separation of line and frame synchronizing impulses is effected by the use of a gas discharge tube 10 which is ignited only by the longer duration impulses. The demodulated synchronizing signals from a signal separating circuit 1 are fed to the line time base 6 and over a condenser 8 to the control electrode 9 of the gas discharge tube having an anode 11 and cathode 12 in a condition ready to strike. A bias battery 13 gives the electrode 9 a positive bias which is below the striking voltage. In shunt with the discharge tube is a condenser 15 which is charged over a resistor 14. Owing to the transfer time of the discharge tube, a discharge takes place only when the electrode is positively biassed by the longer duration frame impulses, and the condenser 15 discharges, an impulse corresponding to the frame impulse appearing in the line 17 and being led to the frame time base 16. The train of impulses may be passed through a delay network and the derived train combined with the original train to produce a resultant in which the pulses are of shorter duration if the characteristics of the discharge tube render this necessary.

Title: Process for the Production of Magnetic Tapes
IPC: G03G5/16
Filed: 1967-07-27
Abstract: 1,193,843. Copying magnetic tapes. AGFAGEVAERT A.G. 27 July, 1967 [29 July, 1966], No. 34602/67, Heading G5R. In a process for producing non-erasable magnetic copies of magnetic tape recordings, movable magnetizable particles are applied to the tape carrying the original magnetic information and are magnetically distributed to form an arrangement in accordance with the magnetic field of the original; the arrangement is then stripped from the original whilst maintaining the distribution. In a first method, the particles are applied to the original as a suspension in a solution of volatile and non-volatile substances and when this solidifies with the particles arranged in accordance with the original field a carrier foil is applied, by casting, coating or sticking, to the solidified magnetic layer and this is then stripped from the original. In a second method, the particles are suspended in a liquid which completely vaporizes after application to the original leaving the particles distributed in accordance with the original magnetic field. A binding agent e.g. cellulose ester is applied which after solidification is removed from the original with the arranged particles. In a third method, magnetic particles are mixed with a thermoplastic resin in a warm state. The mixture is ground on cooling and the granulate when mixed with a granulate derived from thermoplastic resin only is applied to the original and gently shaken. When the magnetic particles are arranged in accordance with the original field the granules are heated and on cooling the layer thus formed is stripped from the original. To enable the copy layer to be stripped easily from the original the surface of the original may have applied thereto vapour-coated layers of SiO 2 , Al 2 O 3  or aluminium or a layer of fat, wax or synthetic film-forming resin. The action of the original field can be intensified by subjecting the tapes to an alternating field during the copying process or by heating the copying layer to a temperature above the Curie point of its magnetic material but which must be below the Curie point of the magnetic material of the original. After copying the copied tape is subjected to a uniform unidirectional magnetic field which may be accompanied by an idealising alternating field. Since the tape is density modulated by the magnetic particles, the information can be reproduced, even if the tape is erased, by subjecting it again to a uniform field. Wavelength halving may be avoided by subjecting the tapes to a unidirectional field during the copying process. If a transparent support and binding agent is used for the copy the tape can be optically played back.

Title: Method of coating a metallic strand with molten metal and apparatus for use therewith
IPC: C23C2/02
Filed: 1965-08-13
Abstract: <PICT:1121556/C6-C7/1> <PICT:1121556/C6-C7/2> In coating a metallic strand 13 with molten metal 12, the temperature of the strand as it enters a molten bath 10 is maintained substantially constant thereby improving adherence and reducing dross formation.  The strand 13 (e.g. strip, tubing or wire) passes through a furnace 14, a hood 16 and the molten metal 12 (e.g. Zn, Al, Sn or terne).  As it passes through the hood, a heat-sensitive photo-detector 19 which operates in the infrared portion of the spectrum senses its temperature and a recording and controlling instrument 21 sends impulses to a control mechanism 23 for heating and/or cooling means 17. Coating may be by the method disclosed in Specification 453,803.  Furnace gases and other contaminants present in the hood are prevented from reaching the optical part of the heat-sensing device by means illustrated in Fig. 2.  A sensing device 25 is mounted at one end of a barrel 26 which screws at its other end into the hood.  The device 25 is protected by a quartz lens 28 which in turn is protected by flushing gas (indicated by arrows) and also by gas entering at 39 and passing through ports 38 to form a conical curtain.

Filed: 1938-12-01
Abstract: 522,413. Gear-cutting. GARNER, J. R. Dec. 1, 1938, No. 34957. [Class 83 (iii)] A gear hobbing or like machine has a reciprocating feed slide carrying an electric motor which operates mechanism for infeed and withdrawal of the slide to positions determined by stop mechanism which switches off the motor when the desired position is reached. The hob head 1 is arranged as described in Specification 522,412 on a cross slide 18 carried by a vertical slide 3 operated by a screwed spindle 5 driven from a shaft 9. The hob is driven from a main drive shaft 17 through bevel-gearing 16, vertical shaft 15 and shaft 12. The cross-slide 18 is driven from 'a motor 19 on the slide. The vertical feed screw is driven from a motor 23 which also drives the hob and work. For the quick return stroke of the vertical slide, the motor is connected directly to the feed shaft and the work and hob drives are interrupted by means of clutches 21, 22, operated by an electrically actuated plunger 20. The motors 19, 23 are controlled by automatic switch gear. The slide 18 is actuated by means of a worm wheel nut 25 threaded over a bush 26 which is constrained by a key 29 to have an axial movement relative to the nut which is driven by motor 19 through bevel gearing 35, and worm gearing. The screw 24 is normally axially fixed so that as the nut is rotated it moves over the bush with the cross slide and imparts approach and withdrawal movement to the slide 18. The depth of feed is manually adjusted by rotation of the spindle 24 which engages a two-part nut 36, 37 secured to a bracket 38 on the vertical slide. The manual mechanism comprises a spindle 40 connected by bevel-gearing 41 and gears 44, 45, to the spindle 24. For stopping the motor 19 after approach and withdrawal feeds of the hob switches C, D are provided and the motor is alternately started in opposite directions. When the nut 25 reaches the end of its travel in either direction, the bevel gearing 34 becomes locked and continued rotation of the motor forces back a clutch sleeve 50 and actuates a lever 52 for operating one of the switches C or D. The lever 52 is positioned alternately opposite the switches C and D by means of a rod 54 operated by a bevelled face on the head 27. In operation the cycle is started by means of a switch A and after the hob has been fed in and the down feed has been completed a cam M actuates a switch F to energize motor 19 and withdraw the hob slide after which motor 19 is stopped by actuation of switch D. A cam projection M2 also actuates a switch E for reversing the motor 23 and returning the feed slide upwards and also energizing the plunger 20. At the end of fast upward feed the motor 23 is de-energized. The coolant pump is motor driven during the required periods of the machine cycle. Switches are also provided for inching the hob head in either direction both vertically and horizontally.
