Jan. 2, 1953 [Jan. 2, 1952], No. 170/52, Class 38(4) In a discharge lamp dimming circuit arrangement wherein one or more hot or cold cathode lamps 3 are connected to the secondary winding(s) 2 of one or more discharge current supplying transformers 1 the primary winding(s) 4 of which are connected to A.C. input terminals 5, 6 in series with each other if more than one, and with a variable dimming resistance, capacitance is connected in series with the primary winding(s) and the supply at least when the lamp(s) are dimmed to low brightness, and is of such value as to produce partial resonance with the primary winding(s). Thereby the primary voltage, and hence the lamp voltage and stability are increased, to permit a greater degree of dimming, without flickering of the lamp(s), than would otherwise be possible. As shown, the lamp brilliance is selected by a wiper arm and engaging contact studs A ... K, between A ... F of which are connected resistors 10 and to G ... K of which are connected capacitors 14 . . . 17 and resistors 18 ... 21 in a graded series-parallel arrangement: In other embodiments capacitors only or resistors only are cumulatively connected between studs F, G; G. H &c., in the latter case a capacitor shunting studs F. K, or a single capacitor and resistor shunted by a switch provides only two illumination levels. The transformer(s) may be of the stray-field type. and there may be provided one or more additional ballast impedances (not shown).

Title: Electrodeposition of nickel
IPC: C25C1/08
Filed: 1965-01-05
Abstract: A process of refining nickel in which the nickel is electrodeposited upon conductive islands defined upon the surface of a flexible sheet-metal cathode former by interconnecting lines of non-conductive material, the plated former then being removed from the bath and the deposited nickel removed from the former by flexing the said former. The former must be formed of a material on which the nickel will be deposited semi-adherently, e.g. passivated nickel, nickel-chromium alloy or nickel-chromium-iron alloy and are preferably 0.02-0.04 inch thick.  The interconnecting lines of non-conductive material are preferably as wide as the desired thickness of nickel to be deposited and may comprise paint, varnish, lacquer, tape &c., suitable materials including epoxy resins, acrylics and polyethylenes.  The non-conductive material may be applied to a flat face of the former or to a pattern of depressed interconnecting lines formed in the former.  The formers may be inserted in pairs, back to back, in the electroplating bath.  The deposited nickel should have an internal tensile stress of less than 5000 p.s.i. which may be obtained by incorporating 0.05-0.5 gr./l. of an aromatic sulpho compound e.g. p-toluene sulphonamide, benzene disulphonic acid, naphthalene trisulphonic acid, saccharin &c.

Abstract: 593,755. Non-contact-making relays. ACE ELECTRONICS, Ltd., WELCH. L. C., and COOK, R. J. Jan. 5, 1945, No. 472. [Class 40 (iv)] [Also in Group XXXVII] An alternating-current relay comprises an inductance L, having a high-permeability magnetic core M, connected in series with a capacitance C so that the current flowing from an alternating current source S is normally insufficient to saturate the core, but if the core is saturated momentarily by applying an exciting impulse to the inductance, the resulting increased current due to the reduced impedance of the coil is sufficient to maintain it saturated. The required impulse is applied by the control winding 3, 4, and indication of the change-over from high to low impedance is given either by an armature (not shown) co-operating with the core M, or by a separate relay connected across the capacitance C and responding to the resulting increase in potential developed across it. The Provisional Specification refers to an application of the invention to temperature alarms, the impulse being applied by a thermocouple.
