Title: A process for the manufacture of adenosine-5-triphosphate
IPC: C07H1/02
Filed: 1948-04-26
Abstract: Adenosine-51-triphosphate is manufactured by treating an adenosine-51-triaralkylpyrophosphate with a tertiary organic base, converting the resulting adenosine-51-diaralkylpyrophosphate into a metal salt, treating this with a diaralkyl halogenophosphonate and hydrogenolysing the resulting adenosine-51-tetraaralkyltriphosphate (which need not be isolated but should be freed as far as possible from contaminating matter with the aid of solvents) to remove the aralkyl groups.  In an example, silver adenosine-51-benzylphosphate is treated with dibenzyl chlorophosphonate, the resulting mixture of crude adenosine-51-tribenzylpyrophosphate and silver chloride is heated with N-methylmorpholine in dimethylformamide, the solution is filtered and poured into ether, the resulting precipitate is dissolved in aqueous dimethylformamide, and the solution is neutralized with caustic soda solution, filtered and treated with silver nitrate solution to precipitate the silver salt of adenosine-51-dibenzylpyrophosphate, which is treated with dibenzyl chlorophosphorate in a mixture of phenol and acetonitrile, and a dioxane solution of the resulting tetraaralkyltriphosphate is hydrogenated at room temperature and atmospheric pressure in the presence of palladium oxide and palladized charcoal, the product being isolated as its barium salt.  This is contaminated with barium adenosine-51-pyrophosphate and barium pyrophosphate, the former of which may be removed by reprecipitation of the barium salt at pH 4 and the latter by converting the product so obtained into its acridine salt and recrystallizing from water. Specification 621,094 is referred to.

Title: Method for the Decomposition of Alkali Alumino Silicates.
Inventor: BERGVE EINAR
IPC: C01F7/40
Filed: 1919-05-09
Abstract: 127,566. Bergve, E. May 27, 1918, [Convention date]. Alkali metal compounds; silicon compounds.- Alkali alumino silicates, for example potash feldspar, are decomposed by treating at a high temperature with sulphur vapour. Products termed oxy-sulpho-silicates are stated to be formed by the successive replacement of the oxygen of the potash, and alumina, by sulphur as the temperature is raised. These products may be decomposed by water under pressure, and at a high temperature to give solutions of alkali sulphaluminates. The Specification as open to inspection under Sect. 91 (3) (a) states that the replacement of oxygen by sulphur may be extended to the oxygen of the silica, and that gases containing sulphur dioxide from metallurgical roasting operations contain enough sulphur to be effective for use instead of sulphur vapour. This subject-matter does not appear in the Specification as accepted.

Abstract: 948,652. Converting. PHILIPS ELECTRICAL INDUSTRIES Ltd. April 4, 1961 [April 6, 1960], No. 11993/61. Heading H2F. [Also in Division G1] An apparatus for converting a D.C. voltage into an A.C. voltage comprises a vibrator unit having a stationary electrode 1 and a vibratable electrode 2, a high-frequency generator 11, a driving member, which may be a plate 3, energized from the generator and presenting a reactive impedance to the generator, and a reactor 9 (in this embodiment an inductor) connected in parallel with the driving member and having such a value that the mean resonant frequency of the parallel combination of the reactor and the driving member differs by a small amount from the frequency of the generator. The arrangement is such that displacement of the vibratable electrode varies the resonant frequency of the parallel combination. The voltage to be converted is applied between the two electrodes across terminals 4 so that across the electrodes a modulated high-frequency voltage having a component at the frequency of the generator and a modulating component at the natural frequency of the vibratable electrode is produced whose amplitude is proportional to the D.C. voltage being converted. This alternating voltage may be amplified and rectified in unit 7 and can then be indicated on the meter 8. A damping resistor 10 is included in the circuit so that the response curve is widened and circuit component values are less critical. A second embodiment is described (Fig. 3, not shown), which uses an electromagnetic vibrator arrangement with a capacitor connected across its coil driven from a constant current source, in place of the electrostatic vibrator and inductor.
