Abstract: 335,631. Dreyfus, H. July 2, 1929. Ethyl alcohol and higher alcohols; aldehydes; ketones; esters. - Ethyl alcohol and other oxygenated organic compounds, such as higher alcohols, esters, aldehydes, and ketones, are prepared by heating methanol vapour in the presence of catalysts constituted by compounds of alkali or alkaline earth metals in which the said metals are the sole metallic elements. The term " alkaline earth metals" does not include, magnesium. Suitable catalysts are the oxides, hydroxides, and alcoholates of sodium, potassium, barium, and calcium. The preferred temperature range is 400-600‹ C., but temperature of 800-800‹ C. or more may be employed. The reaction may be effected at atmospheric, reduced, or raised pressure, e.g. 25 atm. The vapour of pure methanol, dilute aqueous methanol, or crude synthetic methanol may be employed, and indifferent gases such as nitrogen may be present. Suitably, the methanol vapour is passed through a copper. silica, or earthenware tube heated to the required temperature and filled with the catalyst, which may be mounted on a carrier, e.g. pumice, kieselguhr, granulated copper, or carborundum. An example is given.

Title: Improvements in modulating systems for high frequency electric signalling
IPC: H03C1/60
Filed: 1925-08-13
Abstract: 260.067. Western Electric Co., Ltd., (Bell Telephone Laboratories, Inc.). Aug. 13, 1925. Phase, changing.-A modulating system for high-frequency telephony is arranged to produce only a single side-band by combining the output from two modulators which are fed by high-frequency currents in quadrature and also with modulating currents in quadrature. The modulators M1, M2 are supplied with carrier oscillations in quadrature by two amplifier: A1, A2 which have their respective grid circuits connected across a resistance 10 and capacity 9 traversed by the carrier wave supplied by the source 3. Speech currents from a microphone 4, Fig. 1, stepped up in frequency, if desired. by modulation with a source 11 are passed to the carrier-wave modulators M1, M2, through two separate filters F1, F2, which are designed to produce a relative phase shift of 90‹ in all the frequency components of the modulating current. The filters F1, F2 are of the band-pass type, and the relative phase shift of 90‹ is effected by using a different number of sections in the respective filters, and by a suitable choice of the cut-off limits. The curves B1, B2 of Fig. 2 show phase retardation as ordinates plotted against frequencies as abscissµ. The frequencies f11, f21, are the cut-off limits for filter F1, and the frequencies f12, f22 the limits for filter F2. In each case the phase retardation increases with increasing frequency but by suitable design the curves B1, B2 are substantially straight and parallel and are 90‹ apart. The baud of modulating potentials fb is chosen as shown in Fig. 2 at a suitable part of the curves. The filter F1 that passes the wider band preferably has one more section than the filter F2, and both are designed to produce 90‹ phase shift per section at a frequency fo that lies within the band fb of modulating potentials. The Specification includes a mathematical analysis of the problem based on the disclosure, in Specifications 102,503 and 142,115. For a particular case in which the modulating potentials lie between 12,000 and 15,000 cycles, fo is chosen at 14,000. The limits of the two-section filter F2 are 8775 and 17775, and of the three-section filter F1, 4180 and 19350. One or both of the modulators M1, M2 may be arranged for modulation of higher order than the second, and in this case one or both of the amplifiers A1, A2 is arranged to produce harmonics as described in Specification 142,571, and the phase difference between the voltage applied to the amplifier grids is adjusted to a suitable fraction of 90‹. The same valve may serve for generating harmonics and for modulating, as described in Specification 250,539, [Class 40 (v), Wireless signalling &c.].

Abstract: 1351001 Direct-contact heat exchangers COMPAGNIE ELECTRO-MECANIQUE 19 April 1971 [27 Jan 1970] 20438/71 Heading F4K [Also in Division B1] In a gas/liquid contact process, (a) the liquid is compressed to a pressure P 1 , and brought to a velocity greater than about 1 m./sec. at the pressure P 1 , whereas the gas is compressed to a pressure P 0  slightly higher than P 1 , (b) the gas at the said pressure P 0  is introduced into the liquid raised to the said pressure P 1  and circulating at the velocity specified in (a) thus obtaining an emulsion comprising small bubbles of gas evenly distributed in the said circulating liquid, (c) the emulsion formed in step (b) is expanded by passing it along an expansion zone in the form of a nozzle of decreasing cross-section in the direction of fluid flow, its pressure being allowed during this passage to fall to a value P 2 , lower than P 1 , which passage also has the effect of accelerating the gas/liquid emulsion, providing a very intimate contact between gas and liquid, the energy necessary for the expansion and acceleration of the emulsion being derived from the expansion of the gas during said passage, and (d) the gas is separated from the accelerated emulsion of step (c). The liquid may be recycled to step (a), and the energy for the circulation of the liquid may be provided solely by the gas. The process can be used for heat exchange between gas and liquid, for scrubbing of argon in a stream of liquid sodium, extraction of carbon monoxide from a gaseous mixture using a cuprous solution, extraction of carbon dioxide from a gaseous mixture using an arsenious solution or methanol, removal of entrained particles in a gas by washing and catalytic processes. In Fig. 1, gas to be cooled enters through ports T 1 , T 2 , T 3  where it contacts cooling liquid flowing anticlockwise in a continuous circuit. Gas leaves from separator 3 at D. Liquid is drawn off at F for cooling in 5 before returning at G. In Fig. 2, gas passes from inlet 26 via perforated member 27 into liquid circulating clockwise and is separated at 31.
