Title: Improvements in the manufacture of higher alcohols
IPC: C07C29/74
Filed: 1928-03-21
Abstract: 310,623. Davis, W. G., and Imperial Chemical Industries, Ltd. March 21, 1928. Aliphatic alcohols.-The separation of higher aliphatic alcohols such as isobutanol from the crude product of the catalytic hydrogenation of oxides of carbon is effected by distilling the crude product to remove the bulk of the methanol and treating the residue with a salting-out solution. According to the example, a crude product containing 25 per cent of higher alcohols, 60 per cent of methanol, and 15 per cent of water and other substances, is distilled until the residue contains 75 per cent of higher alcohols, 15 per cent of methanol, and 10 per cent of water. The residue is extracted with saturated brine, when a layer containing 92 per cent of higher alcohols is obtained from which the alcohols are separated by distillation, the first runnings being returned to the brine extractor. The brine is distilled to recover the methanol. The distillation of the crude product may be effected in a continuous still, methanol being taken off at the top of the column and the 75 per cent higher alcohol liquor at an intermediate point. The extraction with brine may also be effected continuously by passing the higher alcohol liquor through a tower against a counter-current of brine.

Title: Improvements in or relating to piezo electric crystal oscillators
Inventor: MORTLEY WILFRID SINDEN
IPC: H03B5/34
Filed: 1949-03-30
Abstract: 668,635. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Feb. 10, 1950 [March 30, 1949], No. 8672/49. Class 40 (vi). In a piezo-electric crystal oscillator circuit the crystal is connected as a coupling link between two quarter-wave lines the outer ends of which are connected respectively to the grid and anode of the maintaining valve. The lines may be artificial and of similar or different characteristic impedance; it is stated that shunt elements adjacent the crystal are not critical in value and may be omitted. A resistance shunted across either line adjacent the crystal or across the crystal itself serves to suppress unwanted modes of oscillation, while the desired frequency may be adjusted, over a limited range by means of a variable reactance between the cathode and either grid or anode of the valve. Networks suitable for the purpose are described in the Specification and include a low-pass filter, Fig. 2, in which the crystal is connected across points 3, 6 and the grid, anode and cathode of the valve to points 2, 7, 1 respectively. Alternatives comprise the corresponding high-pass filter, Fig. 3 (not shown), and the analogous " T " networks, Figs. 4, 5 (not shown).

Abstract: 155,162. Hansen, J. H. March 31, 1920. Retractive switches.-In a Morse transmitter for use in telegraphy and lamp signalling, " dashes " are sent to line by depressing a spring- controlled plunger 2 connected to braking-mechanism for retarding the motion. The " dots " transmitter is similar but lacks the braking mechanism. The plunger 2 carries a striker 22 which, on depression, engages the end 4b of the rocker 4 which is pivoted at 12. A wiper (not shown) at the other end of the rocker 4 is thus caused to make contact with a plate so as to transmit an impulse. The striker 22 in its upward movement engages under the end 23 of a cam so that the plunger rotates in the casing 20 and the striker 22 clears the end 4b. The movement of the " dash " rocker is retarded by a leafspring 15 acting on a brade drum 14 carried by a pinion 13 which gears with a quadrant 11 on the shaft 12 of the rocker. The braking effect is regulated by means of the screwed pin 18.

Abstract: 440,402. Preparing fuel ROBERTS, J., 5, Victoria Street, Westminster. March 26, 1934, No. 9469. [Class 50] Fuels such as coke, semi-coke, smokeless fuels, briquettes, and coal have imparted colouration or other superficial effects affecting their appearance by the condensation thereon of vapours, other than heavy tarry vapours, derived from the distillation of coal or other solid carbonaceous substances yielding similar condensable vapours on distillation. A lowvolatile coal, e.g. a semi-bituminous Kent or Welsh coal with a volatile content of about 14 per cent may be distilled at 500-750‹ C. and the volatile products conducted through a rotary casing in which the fuel to be treated is repeatedly turned over for a time dependent on the fuel employed. A high-volatile coal is preferably pre-distilled up to about 500‹ C. The gas and vapour may be forcibly directed as by a fan on to the material. The temperature of the gas and material, the period of treatment and the gas velocity are determined to provide condensation of those vapours imparting the required characteristics. The treating chamber may comprise a producer-like casing, the gases being passed upwardly therethrough. Or it may comprise a cooling vessel in which inert gases or steam circulate and into which are passed the treating gases, comprising those derived from one of a number of coke ovens or retorts, preferably at an intermediate period of the course of distillation. Coke, semi-coke, peat, lignite, and oil shale may be distilled for production of the treating vapours at low or high temperatures, or vapours obtained at both ranges may be used together. The Provisional Specification describes the use as treating agent of coal tar, petroleum, and hydrocarbon liquids, and the quenching of fuel distillation residue in liquor containing oils which impart colouration.
