In the same circuit is also included the induction coil E, which is used for standardizing the galvanometer; this secondary coil is represented in the diagram by three turns of wire wound over a much longer primary coil.
He was associated with Henry Williams Chisholm and others as a member of the Royal Commission of1868-1869for standardizing weights and measures.
Amphiaraus, foreseeing the disastrous issue of the war, at first refused to share in it; he had, however, promised Eriphyle when he married her that, in the event of any dispute arising between her brother and ' See " The Electrolysis of Copper Sulphate in Standardizing Electrical Instruments," by A.
Besides the State departments dealing with weights and measures, there are other standardizing institutions of recent date.
Here is carried out the work of standardizing measuring instruments of various sorts in use by manufacturers, the determination of physical constants and the testing of materials.
In the measurement of woollen and other textile fabrics, as to quality, strength, number of threads, &c., there exists at Bradford a voluntary standardizing institution known as the Conditioning House (Bradford Corporation Act 1887), the work of which has been extended to a chemical analysis of fabrics.
In standardizing a weight for use in India, correction has to be made for the weight of air displaced by the material standard, and for such purpose the normal temperature of 85°, atmospheric pressure 29.8 inches, latitude 22° 35` 6.5" (Calcutta), g at 0.9982515 of g at 45° are taken.
More attention seems to have been given to the matter in the United States of America and in Germany and Russia than in England, but the infinite variety of samples known to the commercial expert, and the impossibility of standardizing those in such a manner as to make readily recognizable what the chemist has treated, renders most of the recorded analyses of uncertain value.
All the data required for standardizing the galvanometer can in this way be determined with accuracy.
