[Class 37.] In relatively long units of the type in which a resistance wire is embedded in a compacted mass of insulating powder enclosed in a metal sheath, as described in Specification 144,767, [Class 37, Electricity, Measuring &c.], displacement of the resistance wire while filling or compressing the sheath is avoided by distorting the sheath so as to form a number of reduced portions along its length and thereby hold the resistance wire and its terminals central. The powdered insulating material is inserted in the sheath, which is then re-shaped to remove the reduced portions. As shown in Fig. 3, the resistance wire 11 is attached to terminals 14, 15, preferably as described in Specfication 198,932, which terminals are attached respectively to a disc 18 and a star washer 20 which are received in counterbores in the sheath 12. The sheath is then shaped, for example by a press, to provide reduced portions 12a at intervals along its length, these reduced portions preferably being in pairs at right-angles to each other, as shown in section in Fig. 4. The sheath is then held vertically in a vibrating machine with the star washer 20 uppermost and filled with magnesium oxide or other insulating powder. A solid washer is placed over the star washer 20 and both ends of the tube pinched or bent over to retain the end washers.. The entire unit is then passed through a swaying or rolling machine to reduce the diameter, increase the length, and compact the insulating powder. The flattened portions of the sheath are removed by the first pass or two through the swaying machine. The washers 18, 20 are finally cut off and the ends of the unit squared off. The indentations formed in the sheath may take the form of single crimps progressing from one end of the sheath to the other, each crimp being positioned at 90‹ to the preceding one.
