Title: Improvements in and relating to electric induction apparatus
IPC: H01F41/02
Filed: 1947-08-15
Abstract: 643,490. Transformers and inductances. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 15, 1947, No. 22762. Convention date, Aug. 21, 1946. [Class 38 (ii)] [Also in Groups XXII and XXXVII] In making a transformer &c. core 24, Fig. 2, E- and I-shaped laminµ 20, 21 are pushed between spring clips 38 held in the window of the conductive winding 25. The laminµ 20, 21 are fed successively from both sides.and alternated to stagger the joints. The core 25 is supported by the clips 38 in a well 48 of a hand-reciprocated slider 28 and held by a weighted saddle 33. The slider 28 has side gauging platforms 57 and front guiding supports 64. The laminations 20, 21 are held in vertical magazines 19, 19<SP>1</SP> above forked pushers 62 reciprocated in alternate long and short strokes to feed the laminations singly into the winding 25 by scroll cams 23 on an electric motor - driven shaft 7. Detents 89, 89<SP>1</SP> depress the back edges of the E laminations 20 to ensure their engagement by the pushers 62 and the I laminations 21 are raised clear by members 76 cam reciprocated from the shaft 7. Further detents 79 raise the backs of the E laminations 20 to ensure entry of their legs between the lower clip 38 and the last I lamination, and after insertion, other detents 81, 81<SP>1</SP> reverse this inclination so that the outer legs ride on to the platforms 57. The core is held by dogs 86, 861 and the winding 25 rises from the well 48 as the core builds up. When the stacking is complete the saddle 33 has been lifted to a preset height above the platforms 57 and opens a switch 31 and after a further half revolution of the shaft 7 to insert the final laminations another parallel switch (see Fig. 11, not shown) is opened by a cam on the shaft 7 to declutch and stop the machine. A hand cam 34 raises the saddle for insertion of a winding 25 in the well and can be used as an emergency stop. The slide 28 has two wells 48 for alternate use and a safety switch and plunger prevent stacking with the winding 25 misaligned. Operation. The pusher 62 engages an E lamination 20 and carries it forward below the stack of I laminations 21 lifted by the member 76, and the detent 79 guides it into place between the spring 38 and the last inserted I lamination. The member 81 rides over the pusher and the dog 861 takes the shock. The opposite slider makes a short stroke to insert an I lamination. The pusher 62 then makes a short stroke to insert an I lamination when the member 76 has descended the E laminations being retained by blocks within the magazine 20. An E lamination is finally inserted from the opposite side. This sequence repeats until the saddle switch 31 and the cam switch stop the machine when the slider 28 is pulled aside for the complete core to be removed from the well 48 while the machine operates on the next winding. In a modification more than two shapes of lamination per layer are assembled and the opposite operations may be alternate or simultaneous. In a further modification the machine is operated by a hand crank.

[Also in Division G3] A supply system for a vehicle comprises an alternator and rectifier unit 10 which, when running, energizes the alternator field winding 35 through a voltage regulator 60 and charges a battery 40 through a diode 30. Since the alternator has low magnetic retentivity, the field current at starting is supplied from the battery 40 through ignition switch 48, lamp 90 and resistor 92, and the regulator 60, the lamp 90 being illuminated during this period and extinguished when the battery 40 is being charged. Either the lamp 90 or the resistor 92 may be omitted. The regulator 60 comprises a resistor chain 73 ... 76 connected across the output of unit 10 and, through a Zener diode 80, to the base of a transistor 70 whose collector is connected to the base of a second transistor 65. Variation in the output voltage of unit 10 from its predetermined value affects the diode 80 and thus alters the conductivity of transistors 70, 65 to vary the current through the field winding 35. A temperature-dependent resistor 82 is provided for ambient temperature compensation, and the regulator setting is adjusted to include the volt drop across diode 30. In a modification, Fig. 2 (not shown), the polarities of the unit 10, diode 30 and battery 40 are reversed, with consequent alteration of the connections to the field winding and voltage regulator. In another modification, Fig. 3 (not shown), the negative output lead of unit 10 and the earthed end of the winding 35 are connected together free of earth, the diode 30 is connected between the negative terminals of unit 10 and battery 40, and the output connections to the resistor chain of the regulator are reversed.
