Definitions
- a different method is adopted for obtaining the space required for the expansion of the copper, between the copper conductor and theloading strip. In. this case before the load-.
- ing strip is wound onto the copper line, the latter is coated with a layer of a lac which hardens uniformly, dissolves completely in certain solvents, and the thickness of which corresponds to the required space.
- the loading strip is then wound on over the layer of lac, whereupon after the winding, .it is placed in a liquid which dissolves the lac and is then annealedin a known manner.
- Figure 1 of the accompanying drawing illustrates a continuously loaded conductor according to the present invention.
- a is the copper conductor,
- b the layer of lac and 0 the loading or magnetizable strip.
- Figure 2 illustrates the same conductor after the lac has beemdissolved bv the solvent.
- lacs which can be used for this purpose, for instance: (1) Shellac-'colophony lac consisting of 200 grsrshellac, 150 grs. colophony, 650 grs. spirit. p
- lacs can be completely, removed again with the solvents employed, that is to say the lac referred to under 1) can be removed by means of spirit, that under (2a) by means sitlon inside the loading strip.
- These additions may for instance be fine, short asbestos fibres, mica powder and the like.
- a method of n'lanufacturing uniformly loaded conductors for signalling purposes consisting in coating the conductor with a layer of lac which hardens in a uniform manner, is'soluble in certain solvents and is of a suitable thickness, winding the loading strip over the conductor coated with the said layer then placing the conductor in a liquid which dissolves the lac and finally annealing the conductor and loading strip.
- a method of manufacturing uniformly loaded conductors for signalling purposes consisting in coating the conductor with a layer or lac, comprising substances which dissolve in certain solvents and small amounts of insoluble and. incombustible substances, the lac hardening in a uniform manner and being of a suitable thickness, winding the loading strip over the conductor coated with the said layer, placing the conductor in a liquid which dissolves the soluble parts of the lac, the other substances remaining between the loading strip and the conductor and finally annealing the eonductor and loading strip for the purpose set 10 forth.
