Abstract: 1,064,289. Electric selective signalling. CREED & CO. Ltd. Dec. 13, 1963, No. 49434/63. Heading G4H. [Also in Division F2] The invention is a combination of motion aggregating mechanisms for positioning an output member in accordance with a multielement input code combination. In Fig. 1 (not shown) a motor (1) drives a cam-shaft (2) via a single revolution clutch (3) to compress eight first members (L1a to L8a) against springs (e.g. 4). Selected sets of four sets of electromagnets are energized (G1 to G4) to close selected coupling members (H1 to H8b) to communicate motion of a selection of the first members (L1a to L8a), occurring on decompression of the springs (4), to respective ends of four motion aggregating levers (T12, T34, T56, T78). The centres of these levers are connected to respective ends of two further levers (T13, T57), the centres of which are connected to respective ends of a last lever (T15), the centre of which rotates a typewheel via a rack and pinion. Four of the first members (L1a to L8a) have one coupling member each, the others each have two in series. The four bit input code may be a telegraph code. The typewheel may also be moved axially (no details) to select one of four banks of typefaces thereon.

Abstract: 1,158,050. Heating carbon monoxide-containing gases. ESSO RESEARCH & ENG. CO. 6 Nov., 1967 [13 Jan., 1967], No. 50381/67. Heading C1A. [Also in Division C7] The reaction 2CO-#C + CO 2  and pitting and dusting of metal vessels when a carbon monoxide-containing gas is heated to above 1400‹ F. is inhibited by mixing the gas with 5-1000 p.p.m. of hydrogen sulphide to prevent the reversion reaction, and heating, in the presence of a metal which would catalyse the reaction, to 1200-1400‹ F. only, to prevent metal corrosion. Further heating to above 1400‹ F. is accomplished by partial combustion with 0 2 , either by combustion of a separated portion of the gas with oxygen in a refractory tube and returning this hot gas to the main volume of gas, or by partial combustion of the whole volume of gas. In a process for the reduction of non-oxide, for example, a reducing gas containing C0 2 , CO, H 2 0, N 2  and H 2  at 1600‹ F. is used as reducing agent in a fluidized bed reduction. The product gas is at 900‹ F., and is further cooled to 100‹ F. to remove water, CO 2  being removed in an amine scrubber. The gas is then mixed with make-up gas and 100 p.p.m. of H 2 5 and heated to 1300‹ F. at 10 atmospheres pressure in tubes of ferrous metal. About one-third of the recycle gas is withdrawn from the system and combusted with oxygen in a refractory-lined pipe, giving a gas at about 2100‹ F. This gas is added to the remaining two-thirds of the gas, giving a product gas at 1600‹ F., which is recycled to the reactor.

Abstract: 507,786. Drying oils; coating compositions ; semi-carbazones. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.) Feb. 7, 1938, No. 3800. [Classes 91 and 95] [Also in Group IV] The drying properties of oiticica oil are improved by reacting the oil with semicarbazide or a derivative thereof. Thio-semicarbazide', aminoguanidine, or semicarbazide hydrochloride and a basic substance may be used. Raw oiticica oil or the heated oil (stand oil), or mixtures thereof with other drying oils are treated with the theoretical amount of semicarbazide to react with the keto group in the oil, or less than this amount. In an example, oiticica oil dissolved in ethylene glycol monoethyl ether is treated at ordinary or slightly elevated temperature with semicarbazide' hydrochloride and sodium acetate. After stirring for 2 days, water is added, and if desired, an oil solvent such as toluene. The oil solution is separated and may be freed from solvent, or further additions made to form a coating composition, for example, drying oils, resins, pigments, dyes, lead or cobalt naphthenate, turpentine, benzine, nitrocellulose, chloro-rubber, or polyvinyl compounds. The mixing temperature is maintained below 150‹ C.
