This application is a division of my application Serial No. 416,877, :tiled December 27,.
'i929 for slow electromagnet.
@ne ci the objects of my invention is to provide device which may. he connected in an electrical circuit in series hetween the cury rent supply and the load for regulating the current supplied to the load according to the temperature coefficient oi? resistance olf the device.
Another ohjectgof my invention is to provide a current` regulator consisting of an evacuated or gas iilledtvessel having a pair ofiilaments connected in series and connected to 'terminals lorought out of the .vessel,-the filaments each having diierent temperature y c'oeilicients of resistance and adapted to mutually control the characteristics of the current supplied to a load through circuits including said fila-ments. ,l
Still another object of my invention is to provide a circuit controller in the form of a detachable device adapted to he inserted in circuit hetween a supply source and a load for controlling hy the differential operation,A
the characteristics of the current supplied to the load..
A further object of my invention is to provide atconstruction of current regulator including (independent elements each having dierent temperature coeilcients `of resistance connected with circuitterminals adapted to make contact With circuits leading to a load.
@ther and further objects of my invention reside in the construction of an electrical con- 'trol device as set forth more fully in the specilication hereinafter following by vreference to the accompanying drawing which diagrammatically illustrates the circuitcontroller of myrinvention.I
i lily invention has many applications as a circuit controller and particularly as a device for producing predetermined operation oi an electromagnet in which it may he desired to produce a magnetic condition at a predetermined time after the application of current to a control circuit or vvhereinit may he desirahle to have the electromagnet lose its magnetic characteristics after a predetermined `time interval. 4 n the drawing have shown a single Winding electromagnet at 25 connected in circuit with a voltage supply source 26 and in series with' an incandescent lamp device having an evacuated or gas illed vessel 27 which is arranged to act diierentially for controlling the current through the single winding electroma net 25. The incandescent lam devicef2 includes a carbon lavment 28 aving a negative temperature coeiicient of resistance and the tungsten fila- /ment 29 which has a positive temperature coelflcient of resistance connected in the manner shownto the three Wiresupply circuit connecting to source 26. The in andescent lamp device 27 isprovided yWity terminals 30, 31d and 32 projtecting from the base portion 33. The carbon filament 28 is sup-l 'vported within the evacuated or gas filled vessel 27 on the vertically disposed support 34. The tungsten 1i1ament29 is( suitably mounted within the evacuated or gas filled y'vessel 27 on the support 35./ A conductor 36 serves to interconnect the carbon filament 28 and the tungsten filament-29 in series reintermediate the ends of conductor v36 and connected to the terminal 31 as shown. Thev base y33 is itted into any suitable socket whereby contacts 30, 31 and 32 connectv with the supply circuit 26 and the electromagnet 1 25 as shown.
' With equal ful-l rated voltage applied simultaneously at E and E ing equal in resistance when hot, a momenthe filaments be- Y l tary current will flow in the center leg through electromagnet 25. The total duration ofthis current will be the heating Jtime of both filaments. It will start as amazimum and taper ofi' to zero as the carbon filament comes,yrelatively slowly, up to the full operating temperature.
`W ith equal voltages, andfthe filaments equal in resistance when cold, the current through electromagnet 25 will be zero until the filaments begin to heat. As the tungsten filament heats the current in its leg of the circuit will decrease and asV the carbon heats the current in its leg will increase.
magnet and reach a constant valuep when both fil-aments are up to full voltage.
With constant applied voltage, and the filaments equal in resistance when partly heated, the `current in electromagnet 25 will start at a high value and decrease to zero by the time both perature corresponding to equal resistance.
"After this point is passed the current through electromagnet 25 will increase again but the direction. of energy flow through electromagnet 25 `will be the reverse of what it was lto a certain poi .at the start. The times again will besthe ,heating time of the filaments.
By connecting a magnet in the neutral circuit Ias vindicated it can be made to function as follows: l
1. Pick up its core momentarily while the filaments are heating and dropit again.
In the first'described condition, advantage can be taken of the differential heating of filaments br other elements to obtain a magnetic action after a period of time has elapsed and yet have current flowing in the magnet only for a relatively short time. By varying the heating elements as to materials and resistance and thevoltage and currents the time element ofthe combination may be varied over a wide range. highv coefficient materials nickel, copper or aluminum may be used. For medium and zero coefficient materials nickel-copper alloys, and for negative coeiiicient carbon or` boron.
y A ssume a direct current supply with the device of my invention connected in circuit with the upper supply line, positive, con- The ooi resultant difference flowing through electro- H 25 will rise over a period of time filaments are up to the tem! Vevacuated envelope, with,
For instance for 'said filaments,
nected to the carbon filamentandthe'lower supply line, negative, to the tungsten. With the value of resistance and current given in the table below it will be seen thatthe current flow through the magnet 25 will be 8 amperes flowing upward when cold, zero when the resistances equalize, and 3 vamperes owing downward when hot.
p rIlie device of my invention may be applied to direct or alternating current circuits. `When applied to alternating currentcircuits it may be utilized for inductive. and magnetic effects as set forth in my application Serial No. 416,877, filed December 27, 1929.
While I have illustrated the winding of an electromagnet it should be understood that the device may beeJ motor, a measuring device, a lamp 0r some other form of load other than an electromagnet.
l/VhileI have described my invention in' one of its preferred embodiments I desire that it be understood `that modifications may be made and that no limitations upon my inventionare intended other than are imposed b the scope of the appended claims. i
What I claim as new and desire to secure by Letters Patent of the United States .is as follows:
1. A circuit controller comprising an evacuatedenvelope having a base, terminals eX- tending from said base and a pair of filaments disposed within said envelope, a conductor electrically connecting said filaments Carbon Y Tungsten Dimm enc.,
