摘要： 674,148. Supply systems for space discharge lamps; transformers. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. May 30, 1950 [May 28, 1949], No. 14323/49. Classes 38 (ii) and 38 (iv). The ballast for an electric discharge lamp a comprises an autotransformer having an open circuit output voltage approximately equal to the supply voltage and two series connected and closely coupled primary windings W1, W2 with a loosely coupled secondary winding W3 connected between a lamp electrode and the junction between the two primary windings so that when the lamp is in operation ballasting is effected by the loosely coupled and series connected windings W1 and W3. In the case when the usual starting switch in shunt with the discharge path, Fig. 4 (not shown), is dispensed with a further loosely coupled secondary winding W4 may be extended from the secondary primary winding W2, each secondary being provided with a tapping to provide heating current to the lamp electrodes. The transformer, Fig. 6 (not shown), preferably has a shell type core, with the two primary windings concentrically arranged at one end of the centre limb and the secondary windings similarly arranged at the other end. A single tapped primary winding may be used.

摘要： 649,816. Transformers. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. Dec. 30, 1948, No. 33467. [Class 38 (ii)] A leaky transformer comprises a plurality of windings spaced apart on a core between which windings, or some of them, is inserted a magnetic shunt between the core and an external yoke, the magnetic shunt being a continuous length of insulated magnetic strip material of such structure .as would be provided by winding an even strip of material upon itself into a roll and then subjecting this to pressure between two parallel plates situated tangentially at diametrically opposite sides of the curved periphery. A transformer suitable for use in a twin discharge lamp circuit has main core laminations A which support wind. ings B, C, D. Magnetic shunts M1, M2, M3, M4 are interposed between the windings, being separated from the core and its external yoke, and from the windings, by suitable packing material E. The shunts comprise continuous lengths of insulated magnetic strip material which may be wound in the form of a circular strip material which may be wound in the form of a circular coil and flattened to the shape shown, or may be wound initially in that shape. The winding C may serve as a primary winding, and windings B, D as secondary windings for two discharge lamps (Fig. 4, not shown). Each lamp is provided with a starting switch, preferably of the glow-discharge type. A capacitor provides the desired outof-phase relationship between the currents passing through the lamps when in operation. The windings act as stabilizing chokes after the lamps have struck.

摘要： 647,995. inductances. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. Nov. 6, 1948, No. 28891. [Class 38 (ii)] An inductance coil 3, which may operate as a current-limiting device for a discharge lamp, has a laminated or dust core 4 and is substantially enclosed by a box of magnetic material, such as steel, constituted by parts 1, 2, each part being bent from a single sheet so as to form two sides at right-angles with an end part integral with one of the sides. The parts 1, 2 are suitably positioned during assembly to adjust the air-gap of the choke. The parts are then secured in this position by clamps or wrappings.

摘要： 644,274. Inductances; supply systems for space-discharge lamps. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. Sept. 28, 1948, No. 25214. Drawings to Specification. [Classes 38 (ii) and 38 (iv)] In a circuit arrangement for two parallel connected discharge lamps each started by a glow discharge starting switch and supplied through ballast impedances comprising respectively a choke coil and a condenser in series with a further choke coil to reduce flicker, the two choke coils are loosely coupled so that when the first lamp has started its associated choke coil induces an E.M.F. in that choke coil in series with the condenser so as to increase the voltage across the second lamp until it has started. and thereby ensure operation of the second glow discharge switch. Preferably each choke coil is wound on a laminated E-shaped core with the open ends facing and separated by two similar plates of mild steel or other magnetic material interleaved with spacers of non-magnetic material such as impregnated paper, the two cores, plates and spacers being held together as one assembly by brackets or strips bolted together through the cores.

[Classes 38 (ii) and 38 (iv)] In supplying a consuming device such as a discharge lamp m through a current limiting choke a, the capacity required for power factor correction is incorporated in the choke by making the winding thereof in the form of a thin flat conductor a which is wound simultaneously with, but insulated from a second thin flat conductor b connected as shown. The conductors may be insulated by paper strip or they may be of aluminium coated with oxide as insulation, or they may be in the form of a metallic coating on paper. Specification 465,619 is referred to.

In a low-pressure mercury-vapour lamp having an internal fluorescent coating, the starting strip is secured to the envelope by adhesive tape. The copper or nickel tape or wire may first be applied to the tape, e.g. by spraying conducting material thereon, which may be varnished after assembly. One strip may be connected to one cap and extend to within about “-inch of the other cap; or two strips may be connected respectively to each cap. Alternatively, the strip may be applied only to the envelope part on which wall charges accumulate and may be earthed either by a flexible wire or by a contact on the lamp bracket which penetrates through the adhesive tape.

A discharge lamp L, preferably of the 2-foot. 10-watt type, is operated from an alternating current source M by a step-down autotransformer A having windings B, C for supplying heating current to the filamentary electrodes E, the discharge path, when the lamp is operating, effecting byepassing the winding D of the transformer so that the winding H becomes a series inductive ballast for the lamp. The several windings are disposed on a single core mounted closely adjacent to and parallel to the lamp so as to serve as a " starting strip ". The Provisional Specification refers to Specification 650,168.

[Class 38 (iv)] Automatic reduction of the heating current supplied from a transformer L2 to the filamentary electrodes H 1 , H 2 of a discharge lamp F when the lamp starts is effected by including in each circuit between the electrodes and associated secondary windings L5, L6, a choke L3, L4 respectively of inductance less than that of the associated secondary winding and arranged such that the voltage across the secondary winding is opposed by the voltage across the respective choke due to the lamp current, and hence effect reduction or cancellation of the heating current. A condenser C may be included in the discharge circuit to improve starting. Specification 31284/46 (as open to inspection under Sect. 91), is referred to.

摘要： 643,637. Inductances. EKCO-ENSIGN ELECTRIC, Ltd., and STICKLEY, W. A. Aug. 7, 1948, No. 20886. [Class 38 (ii)] A ballast for use with an electric discharge lamp comprises two inductance coils c, d mounted on a common core e and arranged so that the adjacent poles of the windings are similar, the electrical characteristics of the ballast being adjusted by variation of the distance between the coils, the coils being permanently fixed after adjustment, e.g. by impregnating the whole assembly in a thermosetting material. The heavy broken lines indicate the paths of the magnetic flux so that the spaces g form air gaps in these paths. Movement of the coils towards each other causes the fluxes across the air gaps to be bunched together having an effect similar to that of increasing the length of the air-gaps.
