Title: Improvements in or relating to oscillographs
IPC: F02M29/06
Filed: 1922-02-22
Abstract: 192,299. Hartmann, J. F. G. P. Feb. 22, 1922. Current meters; phase differences, measuring. -An oscillograph comprises a liquid jet, preferably mercury, flowing across a magnetic field at right-angles to the jet when currentless, and optical means for projecting the point of intersection of the jet and a plane perpendicular to it. the voltage to be recorded being applied to the jet or to the field circuit and producing a movement of the jet varying with the wave. form of that of the applied circuit. In one form, Fig. 3, a mercury jet J flows from a nozzle N across a magnetic field F and strikes an electrode E, a microscope M projecting the jet upon a transverse slot S in a guide G, through which a photographic plate or film is passed. In this construction the jet is illuminated from behind, but it may be illuminated from the side or the front by using a concave mirror D, Fig. 4. In another construction, Fig. 5, two jets J, J<2> are employed for voltage and current curves, the images in the undeflected condition coinciding. Each jet strikes separate electrodes E, E<2> insulated from one another, and the two jets may be spaced an equal distance from, and in a plane at right angles to the optical system, and in this arrangement their images may also coincide when the jets are currentless. For recording phase displacement, Fig. 9, a single jet when currentless impinges against an insulating member P between electrodes E, E<2> electrically connecting them. Variations in the voltage wave-forms produce a movement of the jet to connect one or other of the electrodes, giving an oscillogram shown in Fig. 11. The phase displacement can be recorded by using a commutator for momentarily inserting one or other of the voltages, or a synchronous commutator can be employed. Fig. 12 shows a synchronous mercury jet commutator K described in Specification 102,977, [Class 38 (ii), Electric currents, Converting &c.], and connected in series with the oscillograph jet J, producing an oscillogram as shown in Fig. 14.
