a subject of the King of Ii'ussiar'aml ream ing at Berlin, Germany, have invented a certam new and .useful Improvement in the Production of Incandesceiit-Eleetriollamp Filaments, of which the following is a specification.
Thepl'esent in'vent-im'i relates to tl1e 'pro-' duction of filaments for incandescent electric lamps, particularly forlampsof low current requirement. The lamp filaments are of -('a1'- v bon coated with an element 'of'the antimony"- arsenlc group, that is to say', coated with either antimony or arsenic.
p The proeess of making the filaments may be carried out as follows: The carbon tilamerit, preferably one madeby the eh-loi'id of .ZlIlC process is first treated with acetic acid emcoon and then .glowed or heated to a red heat lnantunol'ifvhydrogen gas (SblfL-J 0r arsen c hydrogen gas (AsH [whereby antimony 'or arsenic, as' the case may be, is deposited .upon, the' -filament.
This;preparatory treatment may take place I in aISpec-ial-receptacle )or in the lamp bull)- itself. To increase the illuminating power. of the tilanient', -a drop"of 'mercury maybe introduced into-the tube, whi'clr'lsthen. subjected to the exhausting p rocess, -nntii l" as high a \-'ae'|u-n'n possible-is obtained." In. case mercury is tl n|s' en ip lo yed i-the filament eovered' with the element of the antin'iony-arsenie .gro'up described is given a treatment wlth ca'rbureted" l 1ydrogen Ill order vto'fdep'oslt on the ant mony jo'r arsenie"eoating a layer ofearlmn; whi'eh protects the arsenic orantimony eoatmg from the 'amal' amatin' or oxidizin ,efi'eet Speeiflcatiou of Letters Patent.
