RECTIFYING INSTALLATION Filed March 16, 1928 Patented Apr. 5, 1932 UNITED STATES PATENT OFFICE J OI'IANN ES GYSBERTUS WILHELM MULDER, OF EINDHOVEN, NETHERLANDS, ASSIGNOIR TO N. V. PHILIPS GLOEILAMIENFABRIEKEN, OF EIND'HOVEN, NETHERLANDS, A
LIMITED LIABILITY COMPANY RECTIFYING INSTALLATION Application filed March 16, 1928, Serial No. 262,299, and in the Netherlands May 7, 1927.
vas they vary their resistance with the temperature. When the current passing through the Wire increases the temperature, the resistance will likewise increase, so that the total increaseof current is limited. Therefore, such variator resistance wires are employed to keep the current in the electrical apparatus constant.
The bulb in which said wires are mounted is properly called a resistance lamp or variator.
According to the invention, one or'more resistance wires may be provided between the current-supply points, with one or more branches.
The rectifying installation according to the invention comprises a multiphase rectifier and one or more high-tension coils in addition to the usual secondary transformer coil consisting of several parts, at least one .resistance lamp according to the invention being utilized for theresistances required.
Figure 1 of the accompanying drawings represents resistance lamps, which may be used in the installation, according to the invention, the diagram of connections of the latter being represented by Figure 2.
Referring to Figure 1, resistance wires are mounted within a glass bulb 1 which optionally may contain a gaseous filling, 2 is a cap provided with the usual contact pins 11. According to this mode of realization, there are two separate resistance wires 8 and 9 which are calculated for different current intensities. The current is supplied by a pole wire 7 3 to the resistance wire 8 and after passing through the latter it is carried away by a pole wire 6. To the wire 3 is secured a pole wire 4 which serves to supply current to the resistance wire 9, which is provided in the middle with a branch 7 After this branch begins that part of the resistance wire 9 which is indicated by 9 and whose pole wire is denoted by 5. The wires 9 and 9 are so calculated that during the operation of the lamp currents of the same intensity flow through the said branches.
The four pole wires, 3, 5, 6 and 7 are electrically connected to the contact pins 11. A central rod 10 secured to a stem 12, carries four sets of supporting hooks 13 and 14 to which the resistance wires are secured.
Figure 2 represents diagrammatically a rectifier circuit arrangement according to the invention, which comprises a full-wave rectifier 27. To operate this rectifier, the primary coil 15 of a transformer is connected to a suitable source of alternating tension. The installation can be utilized for halfwave or full wave rectification.
The transformer is provided with three secondary windings. Of these windings 19 and 23 are adapted to produce an equal voltage, while the third winding 25 has a larger number of turns and produces a higher secondary voltage than do the windings 19 and 23. The windings 19 and 23 are used for full wave rectification, while the winding 25 is used for half wave rectification in circuits including variator resistances, which circuits will be more fully explained hereinafter.
Thus it will be seen that for half Wave rectification the windings 25 and 19 are connected in series, thereby ensuring a higher voltage output than would be available with the winding 25 alone.
By connecting the negative terminal of the battery to be charged to the negative point of connection 16, the battery is charged by means of full-wave rectified current, namely in the following manner: starting from the positive terminal 18, the charging current flows through the battery via the point of connection 16. through the resistance 9, through the coil 19 and during one half wave of the alternating current from the anode 20 to the cathode 21. through a part of the heating current coil 22 and back to the positive terminal 18. During the other halfwave the current flows from the point 16 through the resistance 9', the coil 23, the
According to the invention, the three resistances denoted by 8, 9, and 9 are assembled in a single lamp. The resistances 9 and 9 are traversed by currents of the same intensity and as such may consequently be used the resistances denoted in Figure 1 by 9 and 9. In that case the battery will be charged by one half-wave of the alternating current. The charging current flowing in'this case, takes the following path: starting again from the positive terminal 13, through the battery to be charged, through the coil 3, through the resistance 14, through the coil 2, from the anode 8 to the cathode 10 and back to the positive terminal 13. Y
According to the invention, the three resistances denoted by 5, 6 and 14 are assembled in a single lamp. The resistances 5 and 6 are traversed by currents of the same intensity and as such may consequently be used the resistances denoted in Figure 1 by 9 and 9.
