Abstract: 834,841. Gas turbine engines. ROLLSROYCE Ltd. May 29, 1958 [May 29, 1957], No. 17110/57. Class 110 (3). [Also in Group XXXVIII] A warning system for indicating incorrect functioning of a combustion chamber of a gas turbine engine having a plurality of such chambers, comprises a plurality of pairs of dissimilar metals connected in an open-ended series, the junctions between the pairs being positioned so as to be subjected to the temperature issuing from different combustion chambers or groups of combustion chambers, the open ends of the series being connected in a circuit adapted to operate directly or indirectly a warning device, the junctions of the metals being so connected that should one junction be subjected to a temperature substantially different from the others, a current is induced in the circuit which causes the operation of the warning device. In the engine shown in Figs. 1 and 2, a plurality of thermocouples 13 is disposed in the jet pipe 12, each being disposed in line with a combustion chamber 11. The thermocouples are connected in open-ended series by wires 14, the free ends terminating in output terminals 15, 16. The terminals 15, 16 are connected to an amplifier 17 which is connected to a relay 18 which is in turn connected to a warning light 19 and an electromagnet 20. The electromagnet is arranged to move the movable part 24 of the valve 24a so as to reduce the supply of fuel to the injectors 32 in the event of change of temperature detected by one of the thermocouples 13. In a second embodiment, a plurality of arcuate pairs 36, 37 of dissimilar metals (such as nickel aluminium alloys and nickel chromium alloys) are disposed so as to form an open-ended ring of aerofoil section which is supported within the jet pipe by means of insulated radial struts 34. The terminals 15a, 16a are connected to warning and control apparatus as in Fig. 1. In an engine having say nine combustion chambers, the chambers can be divided into groups of three and one junction can be disposed downstream of each group of three chambers so as to sense the general temperature of the group.

Patent GB-367680-A (GB)
Title: Process for the manufacture of alkylesters of carboxylic acids
IPC: H04M3/523
Filed: 1931-06-16
Abstract: Carboxylic acid esters, especially those of ethyl and propyl alcohol, are obtained by heating mono- and dialkyl sulphates or mixtures thereof with free sulphuric acid, with carboxylic acids such as formic, acetic, or benzoic acid under conditions such that during the process, after any free sulphuric acid initially present has been eliminated, no free sulphuric acid or only very small quantities thereof appear.  This may be effected by adding to the alkyl sulphates, which may be obtained by the absorption of olefines in sulphuric acid, a sufficient quantity of a neutral sulphate to fix any sulphuric acid originally present or produced during the process in the form of acid sulphate, or by first adding enough magnesium oxide, sodium carbonate, or the like to neutralize the free sulphuric acid, and subsequently adding a further sulphate.  Ammonium sulphate is a suitable addition, since the bisulphate furnace can be utilized for washing out ammonia from the crude gas containing olefines. Phosphorite is also suitable, superphosphate being formed as a by-product, and secondary phosphates may also be used.  Examples are given describing the preparation of ethyl acetate, formate, benzoate, crotonate, laurate, and succinate, propyl and butyl formates, and propyl acetate.  The starting materials in each case are mixtures obtained by absorbing the corresponding olefines in sulphuric acid. In one example potassium sulphate is used as an addition to fix free sulphuric acid.
