Description
Metalowe trzonki zarówek czesto po¬ woduja w fabrykach chemicznych skargi i uszkodzenia, poniewaz nawet w szczelnych oprawach, znanych dotychczas, czesto u- legaja silnemu nagryzaniu, Ninie jsizy wy¬ nalazek dotyczy trzonka zarówki, którego styki sa wykonane z materjalu wytrzyma¬ lego na dzialanie kwasów i odpornego na nagryzanie. Takim materjalem moze byc w zwyklych warunkach atmosferycznych lub fabrykach chemicznych, gdzie warunki sa stosunkowo lagodne, metal, np. stal nie- rdzewiejaca Kruppa lub podobne stopy metali (stal krzemowa). Gdzie jednak wy¬ magania sa ostrzejsze, trzonek zarówki mo¬ ze byc wykonany z wegla lub grafitu, a mianowicie w ten sposób, ze sklada isie z dwóch prasowanych czesci.Rysunek przedstawia zarówke z trzon¬ kiem weglowym. Zewnetrzny biegun ma ksztalt malego cylindra A, zaopatrzonego w gwint zewnetrzny, a wewnetrzny biegun utworzony jest z precika weglowego B.Celem polaczenia styków weglowych z drutem zarówkowym C zewnetrzna po¬ wierzchnie cylindra weglowego A i jeden bok precika weglowego B powleka sie me¬ talem, co umozliwia przylutowanie drutu.Ostateczne zmontowanie odbywa sie na¬ stepnie w ten sposób, ze przestrzen D mie¬ dzy cylindrem, precikiem i wsadzona gru¬ szka szklana wypelnia sie w znany sposóbmater jalem izolujacym i laczacym sie do¬ brze z weglem. Takie trzonki weglowe lub grafitowe sa w najtrudniejszych warun¬ kach zupelnie pewne w uzyciu i odporne. PLMetal bulbs' caps often cause complaints and damage in chemical factories, because even in sealed fittings, known so far, they are often subjected to severe biting. The present invention concerns the bulb cap, the contacts of which are made of a material resistant to the action of acid and bite-resistant. Such material may be, under ordinary atmospheric conditions or chemical factories where conditions are relatively mild, a metal, eg Krupp non-rusting steel or similar metal alloys (silicon steel). Where, however, the requirements are sharper, the base of the light bulb may be made of carbon or graphite, namely by consisting of two pressed parts. The figure shows a light bulb with a carbon base. The outer pole is in the shape of a small cylinder A, provided with an external thread, and the inner pole is made of a carbon stalk B. To connect the carbon contacts to the bulb wire C, the outer surfaces of the carbon cylinder A and one side of the carbon stalk B are coated with metal, which enables the soldering of the wire. The final assembly takes place in such a way that the space D between the cylinder, the stamen and the inserted glass lump is filled in a known manner with an insulating material and well bonding to the carbon. Such carbon or graphite shanks are absolutely reliable and resistant under the most difficult conditions. PL
