Patent GB-388529-A (GB)
Title: A process for the production of a new alkaloid from ergot
Filed: 1931-12-30
Abstract: Sensibamine, a new alkaloid, is obtained by extracting ergot with a suitable organic solvent, such as benzene, chloroform or dichlorethylene.  The solvent used must not transform the sensibamine into an insoluble material; for this reason methyl and ethyl alcohols, ether and acetone are unsuitable.  Thus ergot, preferably after extraction with petrol ether, may be mixed with alkali of lower alkalinity than hydroxide of soda, e.g. hydrate of magnesia, and the mixture extracted with a non-reactive solvent. From this solution the crude bases are extracted by acidulated water, freed from the latter by alkali and extracted by a non-reactive solvent, being then recrystallized from chloroform or dichlorethylene until the crystals have a melting point of 180-184 DEG  C., and in chloroform a specific rotation [a ]<30>D of + 125 DEG .  Alternatively, the crude bases may be precipitated as slightly soluble inorganic salts, e.g. sulphates, from a suitable solution, e.g. of alkaloid acetates, derived from the crude extract, then decomposed by bicarbonate of soda, dissolved in chloroform and recrystallized from dichlorethylene.  Specification 286,400, [Class 2 (iii), Dyes, &c.] is referred to.  The Specification as open to inspection under Sect. 91 referred to the use of dioxane as a non-reactive solvent, and to the transformation of the insoluble material produced by reactive solvents into sensibamine by the action of such reagents as glacial acetic acid. This subject-matter does not appear in the Specification as accepted.

Abstract: For the early detection of the faulty feeding of a printing copy (D), the position thereof on the transporting cylinder (5) is scanned visually by a stationary photocell control device (6) and a member (4), e.g. a reflector or a mirror, which is secured on the transporting cylinder (5) between the grippers of a gripper row. The length of the member (4) in the circumferential direction corresponds to the permissible tolerance for the position of the beginning of the printing copy on the transporting cylinder (5); the uncovered part (b) of the member (4) is scanned and a corresponding actual pulse number (b') is produced therefrom which is compared with a reference pulse number, e.g. corresponding to the central position of the printing copy on the member (4). The difference between the actual pulse number and the reference pulse number is used for regulating the machine, if appropriate also for shutting it down. <IMAGE>
