Title: Improvements in or relating to dicyandiamide and formaldehyde condensation products and method for making the same
Inventor: SELLET LUCIEN
IPC: D06M15/423
Filed: 1951-08-10
Abstract: Water-soluble resinous condensation products are produced by heating 1 mol. of dicyandiamide with at least 3.6 mols. of aqueous formaldehyde at a pH above 7 and at a temperature not above the boiling-point until the condensation product has passed through the stage of being insoluble on extreme dilution to that of being soluble on extreme dilution.  The solution may then be evaporated to dryness, e.g. by spray drying, to yield a solid water-soluble resin.  The pH of the reaction mixture is adjusted by addition of borax, sodium carbonate, tertiary sodium phosphate, or dilute caustic soda.  The condensation may start with a neutral or slightly acid solution but the pH must be increased above 7 before the insoluble stage is reached.  The products may be mixed with wood flour or glass fibres and used for moulding, or may be used in aqueous solution for coating or impregnating materials such as paper, textile fabrics, leather, cork or wood, the resin being insolubilized on the coated material by heating and/or by addition of catalysts, e.g. ammonium chloride, ammonium sulphate, ammonium sulphocyanate, or ammonium hydrogen phosphate.  The resins may also be alkylated by reaction with an alcohol, e.g. methanol, ethanol or butanol in presence of sulphuric acid, or by reaction with sodium hydroxide followed by a dialkyl sulphate. The ethers are soluble in organic solvents and the solutions are useful for coating or impregnating.  A number of examples are given using varying quantities of formaldehyde and different agents for adjusting the pH of the reaction mixture.

Filed: 1918-11-18
Abstract: 142,886. Hall, A. A. Nov. 18, 1918. Wireless signalling; electric oscillations, producing; aerials. - In a system of wireless telegraphy or telephony in which thermionic valves are used for reception or transmission, or both, the usual aerials are not employed. The receiving and transmitting stations both have a double earth connexion, the two earths at one station being spaced apart by a distance of half a mile or less. The connexions to the earths are made by insulated conductors lying on the ground, no elevated aerials being used. The instruments may stand on the ground or be beneath it, as in a dug-out. Fig. 1 shows a receiving- station with earths at F, R. There are two reacting oscillation circuits, namely (1) the circuit including the earths F, R, filament A', anode A<3>, reactance N, condenser Q in shunt with the telephone receiver P, and high-tension battery O, (2) the circuit G comprising the adjustable inductance J and variable condenser H, the latter being connected on the one side to the grid A<2> and on the other side to the negative end of the filament. In a modification, the telephones P are replaced by the primary winding of a step-up transformer, the secondary of which supplies potential to the grid of a second valve, which influences in the same manner a third valve. The plate-circuit of the third valve includes the primary winding of a step-down transformer, the secondary winding of which is connected to the telephones. In a further modification, the oscillation circuit J, H is placed as a loop in the plate circuit, the condenser H shunting the coil N instead of the coil J. Fig. 4 shows a transmitting- station. The grid A<2> is connected to the negative end of the filament through an inductance J' coupled variably with the variable inductance T. There is a closed oscillation circuit comprising the condenser V, variometer S, and part of the inductance T, and there is a second oscillation circuit comprising the earths P, F, signalling- battery O, key U, the loop circuit V, S, T, and the anode and filament of the valve. The connexions shown in Fig. 4 may be modified by substituting a direct wire connexion between the batteries 0, D in place of that by the earths P, F, and substituting for the wire between the condenser V and the tapping T' a connexion formed by the two earths.

Filed: 1928-07-03
Abstract: 317,592. British Cotton Industry Research Association, Nuttall, T., and Shorter, S. A. July 3, 1928. Openers, cleaners, etc.; feeding openers, cleaners, &c.-In the treatment of cotton by opening machinery, pneumatic mixing apparatus, blowing room and cleaning machinery, &c., dust and dirt are removed as the cotton is travelling in attenuated form by the provision of high speed dust cages, so arranged that the cotton accumulates in one position on part of the cage, the dust &c. being drawn away by suction through the end of the cage, and is automatically liberated in another position by a supply of clean air drawn from outside the cleaning apparatus, and forwarded to the succeeding devices. In applying the arrangement to a porcupine, opener a, Fig. 1, forming part of an interconnected group of machines, the high speed cage b is situtated at the discharge orifice. The cage b is carried by end spiders b<1>, b<2> mounted on sleeves b<8>, b<9> on a stationary shaft d<1>, and is rotated by a pulley b<10>. The shaft d<1> is supported in cross bars c carried by brackets b<11> from the machine frame. This shaft carries a main diametral damper d carried by spiders d<2>, which also support short circumferential dampers b<6>, b<7>, at each end in the chambers e. The cotton passing from the opener is drawn on to the upper part of the cage and the dust &c. is drawn through into the upper part dx of the cage above the damper d and is drawn away through holes into the end chambers e and thence through ducts e<1> which communicate with a fan. Clean air enters through apertures f<1> in the cylindrical supporting brackets b<11> and passes into the lower half of the cage below the damper d and is drawn through the cage. taking the accumulated cotton with it into the usual trunk y leading to the usual cages. Sheet metal walls g<1> cover the lower part of the cage and converge to the trunk g. A cover plate i encloses the upper part of the cage and a roller h rotating at the same surface speed as the cage is provided between the covers i and g<1>. The high speed dust cage is also described as applied to a Buckley opener forming part of a group of machines for opening and conveying cotton. The cages may be arranged between a Lords opener and a Crighton opener and between the Crighton opener and the usual dust trunk, or may be applied at the delivery point of a hopper feeder before the cotton passes to a conveying trunk.
