Title: Process for obtaining an isoquinuclidine alkaloid from the plants of the genus conopharyngia
Filed: 1959-08-07
Abstract: A purified amorphous isoquinuclidine alkaloid fraction from plants of the genus Conopharyngia is obtained by (a) extracting parts of the plants with methanol and concentrating the extract, (b) removing any resulting precipitate by filtration, centrifuging or decantation, (c) acidifying the clear solution to pH 2.5-4.0 by addition of dilute acids, (d) clarifying the acidified aqueous solution by filtration, centrifuging or decantation, (e) subsequently extracting it first with alkanes having fewer than 8 carbon atoms and then (f) with an aliphatic halogenated hydrocarbon having 1 or 2 carbon atoms or other water-immiscible solvent, (g) concentrating the latter extract, (h) washing it with an aqueous alkaline solution, (i) evaporating it to dryness, (j) triturating the residue with benzene or a mixture thereof with up to the same amount of petroleum ether, (k) filtering the resulting solution through an adsorbent, and (l) evaporating the filtrate to dryness.  Alternatively steps (f) to (j) may be replaced by the steps of adjusting the pH of the solution from (e) to 3, extracting it with benzene, washing the extract with an aqueous alkaline solution, and drying and concentrating the benzene solution; or steps (f) to (l) may be replaced by the steps of extracting the solution from (e) with benzene, diethyl ether or a mixture thereof containing up to 50% of ether, evaporating the extract to dryness, dissolving the residue in dilute acetic acid, saturating the solution with an alkali metal halide, removing any resulting precipitate, basifying the clear solution and collecting the precipitated alkaloid fraction by filtration or extraction.  Tabernanthine is prepared from the foregoing alkaloid fraction by heating it in an alkaline medium (preferably in a solution of an alkali metal hydroxide in a C1-3 alkanol, which is subsequently removed in vacuo), dissolving the residue in such an amount of aqueous mineral acid as to give a solution of pH <4, warming this solution to 20-100 DEG C., basifying the solution, separating the resulting precipitates by filtration or extraction with an organic water-immiscible solvent, and obtaining pure tabernanthine from the filtration or extraction residue by crystallization from a C1-3 alkanol.

Abstract: 1,192,935. Typewriters &c. NIPPON ELECTRIC CO. Ltd. 12 June, 1967 [10 June, 1966], No. 27012/67. Heading B6F. In a teleprinter wherein a pressure roller 6, and a guide plate 18 guide a paper web 20 around a platen 1 and can be moved away from the platen 1 for threading the web into the machine, means are provided for facilitating the insertion of a sheet or sheets 30 for printing without removing the web 20. During normal operation, the web 20 passes over a paper straightener 2 and the plate 18, between the platen 1 and roller 6, under a wire 5 resting on the platen 1 and over a plate 33 deflecting it out of the machine. The roller 6 is mounted on a cranked part of a spindle 7 mounted in the end plates of the machine, and rotation of the spindle by a handle causes the roller 6 to be moved away from the platen 1. The plate 18 has a slot to accommodate the roller 6 and is connected at 36 to a plate 28 pivoted at 29. The edge of plate 28 opposite to the pivot 29 is engaged by the cranked part of the spindle 7, so that as the roller 6 is moved away from the platen 1, the plate 18 is also moved downwardly. A transparent graduated bar 17 is carried by arms 14 mounted on the spindle 7 so that the bar normally rests lightly on the platen but is moved away therefrom as the roller 6 is released. In this position, a sheet or sheets 30 to be printed can be inserted in the machine, the bar 17 being used to align the sheet as shown. During the release operation, a wire 21 at the rear of the platen 1 is moved to press the web 20 against the platen thus preventing slackness in the web which could impede the insertion of the sheet 30. The wire 21 is carried by arms 24 urged towards the platen by springs on their pivots 23. Lugs 35 on links connected to arms 27 fixed to the plate 18 normally hold the wire 21 away from the platen but allow the wire to press the web 20 against the platen when the roller 6 is released. The arms 14 are coupled to the spindle 7 so that during release the roller 6 moves away from the platen 1 just before the bar 17 and during restoration engage the platen just before the bar 17. A swing-over toggle device (16, Fig. 1) holds the parts either in the release or the restored positions. In the release position, a cam on the spindle 7 engages and opens a switch 31 in the operating circuit of the printing mechanism so as to prevent operation of the printing mechanism.
