Abstract: ABSTRACT OF THE DISCLOSURE         A pulse width modulated voltage converter is proposed, which converts a direct voltage to a sinusoidal alternating voltage with low frequency for use as a ringing signal generator for telephone exchanges.  The converter includes a power stage comprising a ferrite core transformer with two switches on the primary side and two switches on the secondary side.  The switches are controlled by control pulses from a pulse width modulator with a variable pulse width so that they are switched with a frequency which is much higher than the frequency of the sinusoidal alternating current and so that a pulsing of the energy flow between battery and load side is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE A high-voltage circuit-interrupting device includes a replaceable container of pressurized arc-extinguishing fluid. A fluid port of the container is closed by a puncturable seal. When an overcurrent occurs in the circuit, the seal is punctured before interrupting contacts of the device open so that the fluid is already flowing when an arc forms between the contacts. Overcurrents are sensed by either a fusible element or a current transformer. Fluid flow before contact opening is achieved by mechanical facilities responsive to the melting of the fluid element or the output of the transformer. The entire device - including the con-tainer, the overcurrent sensor and the mechanical facilities - is at the voltage of the circuit.

Title: Electronic ballast and high frequency supply system  for gas discharge lamps
Inventor: CLEGG JOHN C
IPC: H05B37/02
Filed: 1983-01-12
Granted: 1987-11-03
Abstract: Abstract The invention pertains to an electronic ballast for gas discharge lamps, particularly fluorescent tubes, which supplies them with high frequency AC at proper voltage from a supply of DC, such as a battery, solar cell or rectifier adapted to be connected, if necessary through a transformer, to a commercial source of AC of any voltage, frequency and phase.          The ballast is adapted to be used in combination with an electrical system, e.g., the electrical system of a building, with many electrical connecting means such as fixtures for hold-ing the fluorescent tubes, commercial frequency distribution means for AC at voltage suitable for appliances, small motors, etc., and the high frequency AC distribution system connecting the source of DC to one or more ballasts to supply the tubes to be used in the fixtures.  The ballast includes inverting means comprising a symmetrical class B, push-pull, current limited, dual feedback oscillator and preferably also not only a high frequency transformer to deliver the output of the oscillator to the building wiring system but also a further transformer, e.g., an autotransformer, having its primary winding placed across the terminals of a lamp and having at least one secondary winding for supplying heating current for the filaments of the fluorescent tubes.  This arrangement provides high enough voltage rapidly to heat the filaments and to start the arc in a tube but as soon as the arc strikes the voltage immediately falls to a lower value and the filament current is reduced to a lower level, thereby effecting great economy in operation.          Means for dimming the lights may also be incorporated in the system.  A particularly efficient rectifier utilizes a trans-former having a delta-connected primary winding and a six-winding star-connected secondary with diodes connected to the outer end of each secondary winding to conduct positive and negative current, respectively, to DC terminals, and the central connec-tion of the secondary windings may provide a grounded neutral. for a three wire DC distribution system.

Abstract: ABSTRACT :            A semiconductor device comprising one or more cold cathodes is mounted by means of a weld on a support of a ceramic material so that areas at which emission occurs are situated opposite the openings in the support.  Such a construction has various advantages.  If the support is the end wall of a vacuum tube, the semiconductor body can be cooled in a simple manner, while moreover semiconductor zones can be connected directly.  This results in a saving of lead-through pins in the vacuum tube, which especially in the case of several emission points increases the reli-ability of the vacuum.  Another advantage consists in that the cathodes can be connected through the weld to a common connection on the support, which results in that the various emission points are applied to substantially the same sur-face potential, so that also the electron-optical behaviour is uniform for electrons which are generated at various emission areas.

Abstract: ABSTRACT OF THE DISCLOSURE           A water level gauge with fault detector comprises a column for containing a level of water with a plurality of light sources on one side of the column and a plurality of detector assemblies on an opposite side of the column. Filters are utilized to project red and green light through the column.  Each detector assembly includes a red detector and a green detector with red and green filters respectively. Due to the difference in offset of light beams transversing the column at an oblique angle through water and through air, the green detector is activated by green light when the green and red light passes through the water in the column and the red detector is activated when the light passes through air in the column, that is, above the water level in the column. By a circuit connected to each detector assembly, it is possible to discover the level of water in the column.  Since each detector assembly includes two detectors only one of which must be activated at a time, a false detector is operable to detect any failure in the system whether in the light source or the detectors by verifying that one signal is received from each detector assembly.  If no signals are received from a particular detector assembly or two signals are received from a particular detector assembly, this indicates a fault.
