Patent GB-449534-A (GB)
Title: Improvements in or relating to the manufacture of carboxylic acids and their salts
IPC: C07C51/15
Filed: 1934-12-22
Abstract: Dicarboxylic acids of dihydropolycyclic aromatic hydrocarbons are obtained by reacting an alkali metal with a polycyclic aromatic hydrocarbon, in certain aliphatic mono- or poly-ethers or cyclic ethers, alone or mixed with other compounds, as solvents, to form the alkali metal hydrocarbon addition product, followed by conversion to dicarboxylic salts by reaction with carbon dioxide. Specifications 443,361 and 445,417 are referred to.  The rate of addition of carbon dioxide to the reaction mixture is such as to decolorize the solution without discharging the colour formed on the surface of the alkali metal.  Low temperatures of the range of - 50 to - 80 DEG  C. are preferred.  According to examples: (1) the alkali salts of dihydronaphthalene dicarboxylic acids are prepared by reacting naphthalene with sodium in dimethyl glycol ether under an atmosphere of nitrogen, and passing in carbon dioxide as described, and also performing the reaction in dimethyl ether; (2) alkali salts of dihydrodiphenyldicarboxylic acids are obtained by reacting diphenyl with sodium and carbon dioxide in dimethyl-ether.  The products are the salts of isomeric mixtures of dicarboxylic acids.  Samples have been furnished under Sect. 2 (5) of dihydrodicarboxylic acids obtained from 1 - methylnaphthalene, acenaphthene, phenanthrene, and anthracene.

IPC: F04F5/54
Filed: 1960-10-28
Abstract: 928,661. Cooling reactors. ROLLS-ROYCE Ltd. Sept. 21, 1961 [Oct. 28, 1960], No. 37221/60. Class 39 (4). [Also in Group XXVIII] A pump comprises means for injecting a spray of liquid into a duct so as to create a flow of gas or vapour in a required direction, the pump being such that it produces a volume flow ratio of the gas to the driving liquid of at least 100 to 1. Steam from a nuclear reactor 30 passes via conduit 32 to a heat exchanger 33 where it vaporizes and superheats water condensate from a turbine which passes through pipe 34, feed water heater 34a, flow path 33b, drum 33d and super heating coil 33c. The superheated steam passes through conduit 35 to a sonic or supersonic nozzle 36a of ejector 36 where it entrains steam from heat exchanger 33. After reactor shut down a small cooling flow of steam e.g. 2% of the normal flow is maintained through reactor 30, conduit 32, ejector 36 and pipe 12 by means of water delivered to an atomizing nozzle 15, from an electrical pump 17. A foraminate plate 24 separates chamber 14 and sump 20, the latter having an overflow pipe controlled by a float-controlled valve 23. The condensate is re-circulated by pump 17. In a modification the pump is combined as a unit with the ejector 36. The water pipe 16, Fig. 4, may be connected to deliver to an annular atomizing nozzle surrounding a smaller steam orifice of a nozzle as described in Specification 926,616. Steam from conduit 35 is led via passage 43 to orifice 42a and via tube 42 to the orifice in element 41. Tube 42 has a ring 46 slidably mounted on it through a sleeve 48 and bellows 47. Ring 46 and sleeve 48 form the pintle of a water atomizing nozzle, the water being fed from pipe 16 to the space between sleeve 48 and tubular part 44. When water under pressure is fed to the space, the ring 46 moves to the right forming the atomizing orifice with the chamfered end of part 44. Specification 907,708 also is referred to.

Patent GB-783748-A (GB)
Title: Improvements in or relating to sonic gas analysers
Inventor: MARTIN ALBERT EDWARD
IPC: G01N29/024
Filed: 1954-12-30
Abstract: <PICT:0783748/III/1> <PICT:0783748/III/2> A sonic gas analyser of the kind in which sound is transmitted through the variant gas from an electrically excited source and the phase relation between voltages derived from said transmitter and a sound receiving transducer, or from two receiving transducers one of which receives sound travelling through the variant gas and the other receives sound travelling through a datum gas, is characterized in that the said phase relation is determined by feeding the two voltages to two grids respectively of a multi-grid thermionic valve and indicating the D.C. changes in anode current as the phase angle between the two voltages applied to the said grids varies.  This is a simplification of a described known method in which the phase relationship is determined by an electronic circuit wherein D.C. is caused to flow at a certain point on the A.C. wave used for exciting the sound source and to cease at a suitable point on the A.C. wave derived from the receiving transducer, or vice versa.  This interrupted D.C. is passed through a meter which gives a steady deflection dependent upon the phase relationship of the two A.C. waves.  In this described known system the switching of the D.C. is performed more accurately by squaring the A.C. waves, then differentiating and using the resultant pips of one polarity only (Figs. 1a to 1d, not shown).  In one form of the present invention two tubes 1 and 2 (Fig. 2) are used, tube 1 containing a variant gas and tube 2 a datum gas.  Electrically excited sound transmitters 3 and 4 are situated at one end of the tubes 1 and 2 respectively and corresponding receiving transducers 5 and 6 are situated at the opposite end.  Signals from receivers 5 and 6 are amplified at 7 and 8 and passed to the fifth and third grids respectively of a nonode valve as shown.  It is stated that if these signals exceed 8 volts the anode current/phase angle curve (Fig. 3) is substantially linear and independent of the signal voltages.  Fig. 4 (not shown) indicates a circuit in which a potentiometer is adjusted to give zero reading on a microammeter with the sample tube full of air, and when the sample tube is filled with the gas under investigation the meter indication is proportional to anode current and hence to the phase change.  In cases where greater sensitivity is required a D.C. amplifier (Fig. 5a, not shown) or transistor circuit (Fig. 5b, not shown) may precede the meter itself.
