摘要： A method and a system for providing electrical power to several gas discharge tubes are disclosed. The system includes a master power module and several high-voltage modules. The master power module is constructed and arranged to provide high-frequency and low-voltage power to the high-voltage modules. Each high-voltage module, in turn, provides high-frequency and high-voltage power to a gas discharge tube. The high-voltage modules include step-up transformers with their primary side connected in series to the output of the master power module and their secondary sides connected to the gas discharge tubes.

摘要： A fluorescent lighting system has: (A) a central power supply connected with regular power line voltage and including a number of power supply modules (e.g., eight), each such module having: (i) a parallel-resonant self-oscillating bridge inverter operative to provide a 35 kHz sinusoidal output voltage at a pair of primary output terminals; (ii) a tank-inductor and a tank-capacitor parallel-connected across the primary output terminals; and (iii) several (e.g., four) pairs of secondary output terminals, each connected with the primary output terminals via its own dedicated current-limiting sub- circuit; thereby to prevent a load connected with a pair of secondary output terminals from drawing more than a certain amount of power; thereby, in turn, to render each pair of secondary output terminals fire-hazard-safe; (B) a plurality of lighting fixtures (e.g., 32), each having a fluorescent lamp and a power input receptacle; each lighting fixture also including a power-factor-corrected 35 Khz ballast connected between its power input receptacle and its fluorescent lamp; and (C) a light-weight power cord plug-in-connected between the power input receptacle of each lighting fixture and one of the pairs of power output terminals. Thus, a single central multi-port power supply will serve to power a large number (e.g., 32) lighting fixtures, with each individual lighting fixture connected directly with one of the many (e.g., 32) individual pairs of secondary power output terminals of the central power supply.

摘要： A method and apparatus for heating a metallic material held by a holder such as a crucible which is positioned on a base using an electric furnace. The electric furnace includes a sleeve, an electric heating element disposed on the inner surface of the sleeve, a removable lid for covering a top opening of the sleeve and at least one handle disposed on the outer surface of the sleeve for lifting and removing the sleeve from the base or placing the sleeve on the base. When the sleeve is placed on the base enclosing the crucible, the removable lid is placed on the top opening of the sleeve and an electric current is applied to the electric heating element. Heat generated by the electric heating element and retained in the furnace melts the material contained in the crucible.

摘要： A half-bridge inverter is powered from a constant-magnitude DC supply voltage and provides at the inverter's output a first AC output voltage that is describable as a modified squarewave voltage. This first AC voltage is applied across a series-combination of an inductor and a capacitor, the junction between which is clamped to the DC supply voltage. As a result, a second AC voltage gets established across the capacitor; which second AC voltage is also describable as being a modified squarewave voltage. However, the phasing of the second AC voltage is delayed by approximately 90 degrees with respect to the first AC voltage; which results in the voltage across the inductor being of approximately sinusoidal waveform. A fluorescent lamp is connected in series with a ballast capacitor; and the lamp-capacitor series combination is connected across the inductor, thereby resulting in a nearly sinusoidal current being provided to the fluorescent lamp. Lamp starting aid is provided by a voltage-doubling circuit supplying a high-magnitude current-limited DC voltage across the ballast capacitor for ignition purposes.

摘要： A number of power-line-operated high-frequency multi-output central power supplies are mounted at spaced-apart points on the permanent ceiling above a suspended ceiling. From each individual output of each such power supply, high frequency power is provided by way of flexible conductor means to a lighting fixture mounted nearby in the grid structure of the suspended ceiling below. Thus, high frequency power distribution is accomplished in a hub-and-spoke fashion by way of relatively short lengths of conductors--with each conductor carrying a relatively light current. Compared with the conventional bus-wire system of distributing high frequency power to a plurality of lighting fixtures, subject hub-and-spoke distribution system provides for substantially lower distribution losses and minimized radio frequency interference. Also, this hub-and-spoke system provides for more flexibility in terms of installing and positioning the fixtures in the suspended ceiling.

摘要： Subject high-frequency lighting system comprises the following principal component parts:(a) a power-line-operated power supply operable to supply a high-frequency (30 kHz) output voltage;(b) a plurality of lighting fixtures--with each such fixture comprising one or more gas discharge lamps and series-resonant ballasting means operative to derive the requisite lamp operating voltages and currents from the power supply's high-frequency voltage output; and(c) a bus wire means operative to distribute said high-frequency voltage from the power supply and to each of the fixtures. To protect against circuit failures, which might occur due to excessive socket voltages resulting upon removal of a lamp or toward end-of-lamp-life, a Varistor voltage-limiting means and a self-latching circuit breaker means are used with each series-resonant ballast. The Varistor saves the circuit from immediate self-destruction in case of lamp failure or non-presence; and the circuit breaker serves to decouple the circuit from its high-frequency voltage supply whenever the circuit has been without proper lamp loading for longer than about two seconds.
