Title: Improvements in and relating to a recording titration device for recording titrationcurves
IPC: G01N31/16
Filed: 1959-05-27
Abstract: A recording titration apparatus comprises two motors for producing relative movement of a pen and a recording sheet in two co-ordinate directions, in which the first motor also controls the supply of titrant and in which the resultant of voltage between test electrodes in the solution and the voltage from a potentiometer driven by the second motor is used to control at least the first motor.  Fig. 1 shows the test solution contained in a vessel 1 provided with a stirrer 3.  Titrant is added by a syringe 2 controlled by a first motor 13 which is coupled to a volume-indicating pointer 21 and also drives a pen 11 over recording paper 6.  The recording paper 6 is driven over rollers by a second motor 9 supplied by the mains 23. The extent of p  movement of motor 9 is indicated by a potentiometer 16 fed from a stabilized supply 10.  The resultant of the voltage at the slider of the potentiometer 16 and that between the calomel and the glass electrodes 4, 5 is detected at 15 and used to energize a relay 14 whenever the resultant voltage changes from a predetermined value. Relay 14 energizes motor 13, which adds titrant to the test vessel 1 thus bring the electrode potential towards that at the slider of potentiometer 16.  The rate of addition of titrant is inherently reduced as the equivalence point is approached.  The instrument 19 may indicate the voltage difference, the electrode potential or pH value.  In Fig. 2, the relay 14 is provided with a changeover contact which energizes motor 9 only when the resultant voltage reaches the predetermined value.  Reference is made to <PICT:0922592/III/1> <PICT:0922592/III/2> the use of recording paper in the form of a plane sheet, moved in its own plane.  Reference is also made to movement of the pen in two coordinates across a stationary sheet.  The apparatus may be used to control the pH value of a solution by throwing switch 20 to the right.

Title: Process for the manufacture and production of valuable hydrocarbon products by the destructive hydrogenation of carbonaceous materials
IPC: C10G1/06
Filed: 1937-07-02
Abstract: In the destructive hydrogenation of solid infusible carbonaceous materials, e.g. coal, shale, peat, &c., to produce hydrocarbons of low, middle and high boiling-point ranges, all the reaction products remaining after separation of gasoline and gases are divided into parts of substantially the same composition and one of the parts, on which the pressure has been released prior or subsequent to division, is used as pasting medium for fresh initial material while one or more of the other parts are worked up to fuel oil, lubricating oil, or motor fuels.  The separation of the reaction products is preferably carried out in hot and cold catchpots, the sludge and the major part of the heavy constituents being collected in the hot catchpot while the gasoline and part of the middle and heavy oil is collected in the cold catchpot.  The gasoline is distilled off and the middle oil and heavy oil mixed with the sludge withdrawn from the hot catchpot.  Part of the sludge may be recycled to the reaction chamber.  The mixture is then divided into parts of the same composition one of which is used as pasting medium.  The other part or parts are freed from solid constituents by centrifuging and used directly as fuel oil. Preferably however the materials are further worked up by limited hydrogenation to obtain an improved fuel oil or diesel oil and gasoline.  The hydrogenations are carried out under pressure up to 700 atmos. and in presence of known hydrogenation catalysts and in presence of limited amounts of hydrogen so that only 2-4 per cent hydrogen is taken up by the reacting materials. Bituminous coal is pasted with its own weight of oil comprising 35 per cent middle oil and 65 per cent heavy oils and solids obtained in a previous operation.  The paste is destructively hydrogenated at 475 DEG  C. under a pressure of 600 atmos. in presence of 0,06 per cent tin oxalate and 1,15 per cent ammonium chloride with a throughput of 0,5 kg. coal per hour per litre reaction space.  The products pass to a hot catchpot maintained at 460 DEG  C. from which gasoline, middle oil, and heavy oil pass in the vapour state and are then condensed by cooling.  The condensate is separated from gasoline by distillation to 215 DEG  C. and then admixed with the sludge withdrawn from the hot catchpot.  Part of the mixture is used for pasting fresh coal while the remainder is freed from solids by centrifuging and hydrogenated at 470 DEG  C. and 600 atmos. in presence of 1 per cent molybdic acid supported on browncoal coke with a throughput of 0,7 kg. of coal per litre reaction space, only the asphaltic content being hydrogenated.  A stable fuel oil is thus obtained.

Abstract: 119,354. British Thomson - Houston Co., (General Electric Co.). Dec. 18, 1917. Cut-outs.-In order to short-circuit any one of a number of series-connected electrical devices. for example, electric lamps, the terminals of each device are held in contact with the opposite faces of a disk of aluminiurn, zirconium or titanium, one side (for direct current circuits) or both sides (for alternating current) of the disk being coated with an insulating compound of the metal. for example, the oxide of the metal obtained by electrolysis in a solution of an alkali silicate. Disks coated on one side only are produced by stamping out from a plate doubled on itself and coated by electrolysis on its exposed sides only. The disks normally interpose a very high resistance between the terminals but when, on the breakdown of one of the devices, the full voltage is applied to the disk its insulation breaks down. In the arrangement shown, the lamp-holder is provided with spring clip terminals 3, 4 which clamp the disk 1 when the clips are forced into engagement with clips 7, 8 connected to the current terminals 10, 11.

Abstract: 1,027,704. Rolling. F. MOELLER and K. NEUMANN, [trading as VERWALTUNGSGESELLSCHAFT MOELLER UND NEUMANN OFFENE HANDELSGESELLSCHAFT]. May 8, 1964 [May 8, 1963], No. 19232/64. Heading B3M. [Also in Division G3] A control arrangement for setting the roll gap in a rolling mill comprises a tube 21, attached to an upper backing roll chock 2, and slidable in a tube 22 which is attached, by way of an integral tube 23, with the lower backing roll chock 3 of the mill. The tube 21 has attached to it a transformer 27 and the lower tube 22 a core 28 such that relative movement of the tubes, due to a change in the rolling gap, causes an output from the differential transformer at 34. The tubes which are urged apart by a spring 25, are attached to the chocks 2 and 3 by pins 12 which extend along the axis of rotation of each chock about which the chock rotates when the rolls deflect. The core 28 is attached to a shaft 29 whose height is controlled by an electric motor 32 acting on a recirculatory nut mechanism 31. In operation, the position of the core is first adjusted to give zero output with a desired roll gap. During rolling any signal received at 34 is used to control the fluid pressure on a ram 16 (Fig. 1, not shown) such that the rolling gap is returned to its desired value in which the transformer output is zero. Elastic deformation of the mill under pressure, and also changes in the roll gap due to wear or heating of the rolls may be compensated for. The output from the transformer may alternatively be used to control the screwdown 7 but a prestressing arrangement is preferred. A pull out sled 17, 18 allows withdrawal of the roll assembly for roll changing.
