Patent GB-576480-A (GB)
Title: Process for producing olefinic hydrocarbons
IPC: C07C1/24
Filed: 1943-10-29
Abstract: Olefinic hydrocarbons are produced by dehydrating a monohydroxy alcohol containing at least 4 carbon atoms with an aqueous solution containing less than 5 per cent by weight of a mineral acid.  Normal, secondary or tertiary, aliphatic, naphthenic, terpenic or aromatic alcohols may be treated, generally at about 100-400 DEG  C. and superatmospheric pressures below about 300 atm. Ethers are also obtained from some primary and secondary alcohols. The mineral acid such as hydrochloric, hydrobromic, arsenic, sulphuric, boric, ortho- and other phosphoric acids may be introduced as such or formed in situ by hydrolysis of salts such as halides or sulphates of Fe, Zn, Al, Mg, Cu, Mn, Ni and Co.  The weight ratio of alcohol to the acid catalyst solution may be about 1 : 1.  Batch or continuous operation may be used, unconverted alcohol and catalyst solution being separated and re-used.  The olefins may be simultaneously isomerized, for example n-butyl alcohol with ferric chloride solution gives butene-2 and butene-1 in a molar ratio of about 3 : 1.  Naphthenic and terpenic alcohols, e.g. borneol, isoborneol and terpineol give cyclic olefins, while aromatic alcohols give arylalkenes.  Examples describe the dehydration of normal, secondary and tertiary butyl, tertiary amyl and cetyl alcohols, borneol and isoborneol to yield butenes-1 and -2, isobutene, pentenes, cetene and camphene, the catalysts consisting of various aqueous solutions of ferric chloride, hydrochloric acid, magnesium chloride, sulphuric acid, ferric sulphate, boric acid, arsenic pentoxide or potassium acid sulphate. Where a stainless steel autoclave containing traces of metal halides, probably iron and nickel chlorides, is used, the addition of water only gives satisfactory results.  The effects of reducing the concentration of acid catalyst and of water in the reaction system are shown.

Abstract: 671,224. Coining. TAYLOR & CHALLEN, Ltd. July 12, 1950 [July 12, 1949], No. 18427/49. Class 83 (iv). [Also in Group XXIV] A rotary feed mechanism for a coining press comprises a feed plate 20 having apertures 22, 22a, &c. for receiving, with clearance, a succession of blanks to be fed, the plate being arranged to be located during pressing so that one of the dies 12 can pass through the aperture 22a. The plate 20 rotates above a stationary table 21 which supports the coin blanks in the apertures, and has an opening 23, with a milled collar 24, leading to the bottom die 12. The feed plate is rotated by a Geneva wheel mechanism to a first position to deliver a coin blank into the opening 23 and is then reversed into a second position by means of a spiral land 54 on the pin wheel 50 so that the walls of the aperture 22 are clear of the edges of the opening 23, the upper die then moving down to stamp the coin blank. The upper die is then retracted and the coin ejected to table-top level by upward movement of the lower die 12, whence it is carried by forward rotation of the feed plate to an outlet 25 leading to a hopper 26. A circular extension 57 of the land 54 co-operates with recesses 58 on the wheel 52 to lock the feed plate during stamping. The slots 56 in the wheel 52 are shaped at their ends to ensure that retardation of the plate on coming into its first position is sufficiently early to ensure that the blank comes up against the rear wall of the aperture. Alternatively the blank may be held against the rear wall of the aperture by a pivoted arm operated by centrifugal force on rotation of the feed plate, or by a spring finger, Figs. 5 and 6 respectively (not shown), the holding means being disengaged at the appropriate time by engagement with abutments.
