Title: Improvements in retort mechanism
IPC: C10B7/02
Filed: 1919-02-17
Abstract: 147,965. Smith, C. H. Feb. 17, 1919. Retorts.-Relates to retort mechanism of the type in which the coal is moved progressively through the retort by means of one or more rotary paddle shafts, and consists in providing reducing variable-speed-gear mechanism for driving such shafts, and improved paddle shaft bearing members and supports therefor. In one construction, two parallel shafts with overlapping paddles have intermesh. ing spur-wheels on their ends driven through a worm gear, and either high-speed or lowspeed pulleys and belts, from a motor or a power pulley. In a modification, the paddle shafts, and if desired, the conveyer shaft for feeding the coal into the retort, are driven through change-speed mechanism of the sliding spur-wheel type. The ends of the paddle shafts are journaled in bearing-members 59, 60, which pass through openings in ,end plates or castings 57, 58 and are supported independently of the retort structure by platforms 61, 62, so that the shafts have no contact with the end walls, which are thus not subjected to vibration. The openings in the end walls are of sufficiently large diameter to prevent the shafts from being affected by expansion or contraction of the end walls. Several constructions of the end plates or castings through which tho bearing members pass are described.

Title: Improvements in the manufacture and production of vinyl ethers
IPC: C07C43/16
Filed: 1934-02-10
Abstract: Vinyl ethers are manufactured by leading mononuclear isocyclic monohydroxy compounds in the vapour phase together with acetylene over heated zinc or cadmium salts of organic acids, which are preferably precipitated on substances having large surfaces, e.g. active carbon or pumice stone.  The reaction is preferably performed at atmospheric pressure, but increased pressures up to about 20 atmospheres may be employed, whilst when starting with high boiling monohydroxy compounds, reduced pressure is advantageous.  In an example, phenol vapour and acetylene are led at atmospheric pressure over zinc acetate precipitated on active carbon or cadmium acetate precipitated on pumice stone or other suitable carrier, at 270 DEG C., to produce vinyl phenyl ether.  There may similarly be produced vinyl tolyl ethers from cresols, vinyl xylyl ethers from xylenols, vinyl cyclohexyl ether from cyclohexanol and vinyl benzyl ether from benzyl alcohol. Specification 182,112, [Class 2 (iii)], is referred to.
