Title: Improvements in or relating to electrical transmitting means for recording or signalling systems
IPC: H04L15/04
Filed: 1925-08-07
Abstract: 261,070. Bursill, A., Dunglinson, B., and Healy, H. W., (trading as Electro Flow Meters Co.). Aug. 7, 1925. Tell-tale apparatus. -In an electric signalling system for repeating at a distance the indications of a master instrument, the transmitter comprises a water-cooled electrolytic cell having a movable, electrode which varies the voltage across an indicating circuit. A cell a insulated on its inner surface, contains an electrolyte and a movable electrode h supported by a float j. The electrode h is operated by an arm o of the master instrument through a cone and cup connection m, n and moves between a fixed electrode i and a second electrode formed bv the uninsulated bottom g of the cell. Alternating voltage is applied to the cell across the fixed electrodes and the indicating instrument is connected to the movable electrode and the bottom g of the cell. The voltage across the instrument is therefore a function. of the posi. tion of the electrode h. A layer of oil k prevents evaporation of the electrolyte. The cell is cooled by a water jacket d and temperature errors are compensated by a variable resistance included in the supply circuit. The electrodes may be formed of iron or copper. In such cases the electrolyte, used is sodium carbonate or dilute copper sulphate respectively.

Title: Improved method and device for the manufacture of an artificial thread of varying titre
IPC: D01D5/20
Filed: 1954-07-07
Abstract: <PICT:0758064/IV(a)/1> In the manufacture of viscose threads of varying denier by drawing off the threads from the spinneret by means of a pair of rollers which make intermittent contact, the thread is guided in a straight line through the rollers, perpendicularly to a plane through the roller axes, and steps are taken to prevent overstretching of the thread between the rollers and the winding device.  Overstretching may be prevented by passing the thread in a loop round a weighted jockey pulley, so that the size of the loop may increase whilst the thread is passing freely between the rollers and decrease whilst the thread is being fed by the rollers, whereby excessive tension during such feeding is avoided. The pair of rollers producing intermittent feed may feed the thread in the same direction as it issues from the spinneret, or may feed it intermittently in the reverse direction to give greater variations in denier.  As shown, viscose thread issuing from the spinneret 2 and quick coagulating bath 3 passes through continuously rotating rollers 4, 5 of which roller 5 has recessed portions 6 to give an intermittent feed.  The thread passes through such rollers in a straight line perpendicular to a plane containing the roller axes.  The thread passes in a loop round roller 8 carried on an arm pivoted at 11 and counter-weighted at 12 whereby the size of the loop varies to accommodate fluctuating tension in the thread, caused by the intermittent feed, on its way to the winding device 10.  The intermittent feed rollers may be made of synthetic resin, a casein product or other acid-resistant material having their surface roughened or coated with substances promoting adhesion, or the rollers may be made of such a substance.  One roller may be provided for each spinning point, all being mounted on a common shaft which may be driven by a variable gear; means may be provided, e.g. a worm-driven cam, for periodically altering the variable gear so as to vary the irregularity in thread denier. Specification 554,203, [Group IV], is referred to.

Title: Solutions of organic acid esters of cellulose
IPC: C08B3/22
Filed: 1955-07-11
Abstract: Solutions of cellulose esters of carboxylic acids in organic solvents are improved with respect to their homogeneity, fluidity and filterability by changing the temperature of the solution from a level between 20 DEG  and 35 DEG  C. to a level outside the range - 30 DEG  to 55 DEG  C. at which the solution remains ungelled.  The invention relates primarily to cellulose esters having a D.S. above 2.8 and preferably above 2.9, e.g. cellulose triacetate having an acetyl value (as acetic acid) above 60 and especially above 61 per cent. The ester may be an ester of a fatty acid containing 2-4 carbon atoms in the molecule and may be a mixed ester.  The solvent may be a nitroparaffin, ethylene dichloride, tetrachloroethane, trichloroethane or dioxane, but is preferably methylene chloride alone or mixed with an aliphatic alcohol containing up to 4 carbon atoms in the molecule.  The process is particularly applicable to solutions of high concentration, e.g. cellulose triacetate solutions of concentration above about 14 per cent and especially above about 17 per cent by weight.  The solutions are preferably prepared at 20 DEG  to 35 DEG  C.  In an example, cellulose triacetate of acetyl value 62.5 per cent is dissolved in a mixture of 92 parts of methylene chloride and 8 parts of methanol by weight to give a 20 per cent triacetate solution by stirring for 2 1/2 hours at 30 DEG  C., the solution is cooled to -70 DEG C. and then warmed to about 30 DEG C.  In a second example, the solution prepared at 30 DEG  C. is heated with stirring in a pressure vessel for 5 hours at 70 DEG  C. and then cooled to 30 DEG  C.

IPC: F16H61/456
Filed: 1962-05-25
Abstract: 1,012,299. Hydrostatic transmissions. Y. KUZE. May 25, 1962 [June 6, 1961 (2)], No. 20152/62. Headings F2C and F2D. A hydrostatic transmission comprises a variable-stroke swash-plate pump 6 supplying liquid to two transversely disposed fixed displacement swash-plate motors 7, 7<SP>1</SP>. The pump cylinder block is fast with an input shaft 9 and the motor cylinder blocks 11 are fast with output shafts 10, 10<SP>1</SP>. The pump swash-plate 13 is biased to its maximum displacement position by a spring 30 and is automatically shifted towards its neutral, zero displacement position by a servo piston 24 in accordance with the pressure in the high pressure line of the transmission. The supply and return lines between pump and the motors are provided largely by a generally T-shaped member 16 within the bar of which a tubular member 15 is rotatably mounted. The T-shaped member 16 has a pin 17 eccentric to the input shaft 9 about which a valve plate 18 is freely rotatably mounted, the discharge side of the pump communicating with a crescent-shaped space provided between the periphery of the valve plate 18 and the cylinder block, and the suction side of the pump being in communication with ports 20 formed in the valve plate 18. The tubular member 15 is formed with pins 17 eccentric to the output shafts 10, 10<SP>1</SP> about which valve plates 18 for the motors are freely mounted. The pump discharge passes from the crescent-shaped space to a passage 21 in the T-shaped member and thence through the crescent-shaped spaces provided between the valve plates and the motor cylinder blocks to the motor cylinders, the discharge from the motors passing through ports 20 in the valve plates, a passage 19 formed in the tubular member 15 and a passage in the T- shaped member 16 to the ports 20 of the pump valve plate. For reverse drive the tubular member 15 is rotated through 180 degrees, to effect this grooves are formed part way round the periphery of the member 15 and extending in opposite directions and are filled with balls 55 extending to pistons in cylinders 59, 59<SP>1</SP> supplied with liquid from the high pressure side of the transmission under the control of a reversing valve 33. Liquid from the high pressure side of the transmission is supplied to the servo-piston 24 under the control of a valve 34 which in the normal position shown is biased by a spring 44 to supply high pressure liquid through lines 48, 49 to chambers 27, 28 of the servo-piston 24. The pressure thus tends to shift the piston downwardly to reduce the displacement of the pump against the pressure of spring 30 until a balance is achieved so that the transmission ratio is automatically varied in accordance with the load. The valve 34 can be shifted by actuation of a brake pedal 45 or by actuation of a gear-shift member acting through means 47 to open line 48 and servo chamber 28 to exhaust and supply liquid to the end 26 of the piston to shift the swash-plate 13 to its neutral position when braking is desired. An enginedriven pump 71 supplies liquid to the lowpressure side of the transmission.

Title: Process and apparatus for producing ammonium nitrate
IPC: C05C1/00
Filed: 1966-05-06
Abstract: Ammonium nitrate solutions of concentrations up to 99.8% NH4NO3 are prepared by reacting aqueous nitric acid with anhydrous ammonia at a temperature and pressure which cause the solution to boil, and recirculating this solution by means of the steam produced in it. As shown, the apparatus consists of three superposed chambers 2, 3 and 4, the upper and lower communicating by a reaction tube 5 which extends well into the lower chamber 4 and is flush with the base of the top chamber 2 and by other tubes 6a and 6b which extend into the top and bottom chambers but not as far down into the bottom chamber as the first tube 5.  The middle section contains an inlet 13 and an <PICT:1105466/C1/1> outlet pipe 14 for a fluid (steam or water) and acts as a heat exchanger.  The apparatus is filled with ammonia solution and nitric acid is passed into the second set of tubes 6 through diffusers.  Reaction occurs in these tubes, and the heat of reaction generates steam which circulates the solution up these tubes and down the reaction tube 5.  If nitric acid of less than 62.5% concentration is used heat must be externally supplied by steam through the central vessel 3, if above 62.5% concentration the system is water cooled.  Concentrated ammonium nitrate solution is removed from the base of the top chamber 2 and steam from the very top 18, a set of baffles 17 preventing the removal of the nitrate solution through this outlet.  The process may be carried out at atmospheric pressure or above or below.  The partial pressure of the steam in the reaction vessel may be decreased by the addition of air, gaseous ammonia or a mixture of the two.

Title: Aliphatic sulfate salts of esters of erythromycin or erythromycin b
Inventor: BRAY MALCOLM DAVONNE
IPC: C07H17/08
Filed: 1959-06-17
Abstract: The invention relates to aliphatic sulphate salts of a 1 to 7 carbon aliphatic carboxylic acid or carbonate monoester of erythromycin or erythromycin B, the said sulphate salt being an aliphatic sulphate salt in which the aliphatic group has from 8 to 31 carbon atoms.  The aliphatic carboxylic acid or carbonate ester radical may be acetyl, methoxyacetyl, monoethylsuccinyl, monoethyl-carbonyl and butyryl. The preferred aliphatic sulphates are straight chain alkyl sulphates having 10 to 20 carbon atoms but the aliphatic hydrocarbon radicals of the sulphates may be straight or branched chains saturated or unsaturated, e.g. octyl, lauryl, oleyl, tetradecyl, stearyl, eicosyl, 2-ethylhexyl, linoleyl and tetradecenyl.  Typical salts are the lauryl sulphates of (a) monopropionylerythromycin, (b) monoethylcarbonylerythromycin, (c) monoethylsuccinylerythromycin (d) monoacrylerythromycin and (e) monoacetylerythromycin; mono-methoxy-acetylerythromycin octylsulphate; mono-ethylcarbonylerythromycin cetylsulphate; mono-butyl erythromycin 2-ethylhexylsulphate; monoacetylerythromycin aleylsulphate; and monoacetylerythromycin B lauryl sulphate.  The erythromycin ester in base form may be reacted with the aliphatic p  sulphate or an anionic salt of the ester may be reacted with a cationic salt of the aliphatic sulphuric acid, preferably in a solvent such as acetone in which the reaction product is only slightly soluble.  Alternatively, a solution of a cationic salt of the aliphatic sulphate is added to a solution of the erythromycin ester in the base form and either simultaneously with or subsequently to the addition of the aliphatic sulphate a strong acid is added to the reaction mixtures.  The ester salts are staple under acid conditions, e.g. at pH 2.0, insoluble in water and less bitter than many forms of erythromycin.  They give high blood levels when taken orally (see Group VI).ALSO:Pharmaceutical compositions for oral administration comprise a diluent and an aliphatic sulphate salt of a 1 to 7 carhon aliphatic carboxylic acid or carbonate monoester of erythromycin or erythromycin B, the said sulphate salt being an aliphatic sulphate salt in which the aliphatic group has from 8 to 31 carbon atoms (see Group IV (b)).  Typical salts are the laurylsulphates of (a) monopropionylerythromycin, (b) monoethylcarbonylerythromycin, (c) monoethyl-succinylerythromycin, (d) monoacrylerythromycin, and (e) monoacetylerythromycin.  The ester salts are stable in acid, insoluble in water and tasteless, giving high blood levels on oral administration, e.g. as tablets, capsules or aqueous suspensions. An example is given of an aqueous suspension containing monopropionylerythromycin lauryl sulphate, sucrose, sodium cyclamate, sodium citrate, citric acid, sodium chloride, monosodium glutamate, sodium lauryl sulphate, sorbitan trioleate and flavour.
