Patent GB-799272-A (GB)
Title: Production of intermediates for the synthesis of reserpine and analogous compounds
Filed: 1957-05-03
Abstract: The invention comprises (1) isoreserpic acid lactone of the formula: <FORM:0799272/IV (b)/1> and (2) the isomerization (to reserpic acid lactone series) by heating with an acid the above compound or analogues substituted in the benzene ring by (R11O)n, where R11 is C1-C4 alkyl or benzyl and n is 0 or 1.  Suitable acids are acetic and trialkylacetic.  The process forms a link in the synthesis of reserpine and its analogues, the intermediates being described in Specifications 799,269, 799,270 and 799,271. The lactone: <FORM:0799272/IV (b)/2> obtained as in Specification 799,271 (R = methyl, R1 = acetyl) is ring-closed with phosphorus oxychloride to yield: <FORM:0799272/IV (b)/3> which is then reduced with sodium borohydride to methyl O-acetyl-isoreserpate.  After resolution with di-p-toluyl-l-tartaric acid the product is hydrolysed to isoreserpic acid (hydrochloride) from which the lactone is obtained by treatment with dicyclohexyl-carbodiimide.  The lactone is then isomerized to reserpic acid lactone which may be converted into reserpine. Examples are given of the various steps.  It is stated that the resolution may be effected at an earlier stage.

[Also in Division H1] In bonding a dielectric body to a metal body a film of elemental chromium is vapour deposited on to at least a portion of the dielectric body, a coating of braze material is provided on at least a portion of the metal body, the coating and film are placed in contact and the assembly is heated in dry hydrogen to melt the braze material. The dielectric material may be alumina, beryllia, quartz, glass or sapphire, the braze material may be copper, copper-gold alloy or copper-silver alloy which is deposited by vapour deposition and the metal of the body may be molybdenum. In making an assembly comprising a slow wave structure and its support rods mounted in a barrel, longitudinally spaced portions of the circumferential surface of a support rod 10 of beryllia are vapour coated with elemental chromium strips 12 to a thickness of 0À0001 to 0À001 inch and the rod is then sintered by firing in dry hydrogen at 1325- 1350‹ C. An annular film of titanium carbide is then deposited by cathodic sputtering on the uncoated surface of the rod, the film introducing attenuation and having a tapered configuration. Carbon or graphite may be employed instead of titanium carbide. Chromium strips are then deposited on the attenuating film in diametrically opposed positions. A slow wave structure in the form of a helix 20 of molybdenum has its outer surface flattened and a film 22 of braze material, e.g. copper, is vapour deposited thereon. A number, e.g. three, support rods 10 prepared as above described are assembled about the helix 20 with the chromium strips 12 engaging the braze material 22 and the assembly is fired in dry hydrogen at 1090-1100‹ C. to melt the braze material and form brazed joints between the helix and rods 10. A film 24, Fig. 14, of nickel is vapour deposited over the outer chromium strips 12 and the exposed inner chromium strips are removed in hydrochloric acid. A film 26 of braze material, e.g. 28% copper-72% silver alloy is vapour deposited on the nickel films 24 and the assembly is inserted into a barrel 28 of niobium or of alternate lengths of molybdenum and copper and the resultant assembly is fired in dry hydrogen to melt the braze material 26 but not the braze material 22, e.g. at 840-850‹ C. The slow wave structure may be in ring bar or cloverleaf form.

[Class 139] An automatic winding mechanism having an oscillatory weight 1, Fig. 1, for energizing the main spring of a watch movement comprises a pinion 10 which always meshes with a wheel 9 driven in both directions by the oscillations of said weight 1, this pinion 10 being mounted to effect a limited reciprocating movement, owing to the tangential forces exerted on it by said wheel 9 between two extreme positions in which the pinion 10 meshes according to the direction of movement of the oscillatory weight with one or other of two wheels 19, 20 of a winding train, so that winding is effected in both directions of movement of the oscillatory weight. The ends of the spindle of the pinion 10 are engaged in arcuate slots 11 in upper and lower frame plates of a cage carrying the winding train. As the weight 1 oscillates in one direction the spindle of the pinion 10 is moved to its corresponding extreme position and meshes with wheel 19 or wheel 20 which is constantly in mesh with wheel 19. The wheel 19 is therefore always rotated clockwise by the oscillations of the weight 1 and through the gear train 18, 17, 16, 15 and the pawl 13 rotates the barrel ratchet 12 to wind the main spring.
