Title: The manufacture of lubricating oils
IPC: C10M105/06
Filed: 1928-11-28
Abstract: 325,832. Carpmael, A., (I. G. Farbenindustrie Akt.-Ges.). Nov. 28, 1928. Lubricants for machinery. - Lubricating oils are obtained by submitting one or more alkylated naphthalenes to the silent electric discharge. Other lubricating oils may be present or be added to the viscous product. For example, a mixture of ethyl and propyl naphthalenes obtained as in Specification 273,665, [Class 2 (iii), Dyes &c.], is flowed slowly, at atmospheric or reduced pressure, through a quartz ozonizer, and is treated for 20 hours with a silent discharge produced by an alternating current of 3500 periods per second and 9000 volts. Methyl naphthalene may also be treated. Alkylated naphthalenes with several side chains yield especially satisfactory oils.

Filed: 1937-12-20
Abstract: 485,076. Making leading-in wires by welding. BRUCKNER, R. Dec. 20, 1937, No. 35294. [Classes 83 (ii) and 83 (iv)] In a welding machine for making four-part leading-in wires comprising two outer long wires and short inner sealing and fuse wires, for use in electric incandescent lamps and like vacuum vessels, the outer wires are fed towards each other by separate feed devices arranged in alignment and the inner wires are fed by two similar feed devices arranged parallel to the first and the severed inner wires are received in two pairs of grippers, which are moved in unison to introduce the inner wires between the outer wires for butt welding. The long wires 2, 4 are fed from reels by reciprocating grippers comprising releasable clamps 7 carried by slides 6 having spring- pressed apertured guides 8 provided with cutters 9. During the feeding operation the guides 8 engage fixed stops 10, whereupon the wires pass therethrough into the heads of clamps 14, in which they are held by electromagnetically operated jaws 13. The clamps 14 are movable in the direction of the joints to apply welding pressure by springs 24 tensioned by electromagnets 23. On the return of the slides the cutters engage cam blocks to sever off lengths of outer wire. The intermediate wires 15, 16 are fed by similar devices 20 and received between the electromagnetically operated jaws of grippers 17, which are then given an arcuate movement to place the severed wires between the outer wires. The pairs of grippers are pivoted together and controlled by an electromagnet to apply welding pressure for welding the intermediate wires together. The joints are heated by burners 26, 27. All the joints may be effected at the station A, or the centre joint may be made at the station B or at an intermediate station or the burner 27 may be mounted on the grippers or other part so as to weld the centre joint during transfer to the outer wires.
