Abstract: Abstract of the Disclosure A wound core transformer is described which features low core losses by the addition of magnetic material in those sides of the wound core which are located outside of the coil.   In one embodiment the wound core includes:   a base-core is formed  from two strips  of magnetic material of generally uniform thickness and wrapped about each other in the form of a closed rectangular loop with the ends of each strip offset from each other and the ends of the adjacent strip;  and a filler strip of magnetic material which is interleafed between the two strips forming the base-core with its base disposed adjacent the ends of the strips forming the base-core.   An electrical conductor is disposed opposite the filler strip and wrapped about the two strips forming the base core so as to form a coil.  Under this arangement, the magnetic induction formed in that side of core containing the base portion of the filler strip is lower than that side of the core around which the coil is wrapped.

Abstract: DESCRIPTIF L'amorçage de l'arc électrique s'effectue entre une électrode principale non consommable et une pièce à couper ou à souder sous une atmosphère gazeuse conduite au travers d'une buse entourant l'électrode. Un générateur HF - HT débite d'une part dans un premier circuit d'amorçage reliant l'électrode principale à l'électrode auxiliaire, d'autre part dans un deuxième circuit d'amorçage qui relie l'une des deux électrodes à la pièce à traiter. On obtient ainsi un amorçage en deux temps qui est très fiable quelles que soient la nature de la matière constituant la pièce et le gaz protecteur utilisé, notamment pour le soudage TIG sous hélium d'alliages légers. Application au soudage TIG automatique.

Abstract: ABSTRACT OF THE DISCLOSURE:          A process of afterburning and purifying process exhaust gases, which contain combustible constituents, is simplified and a satisfactory combustion of the process exhaust gases is ensured in that the process exhaust gases and the oxygen-containing gases required for a combustion are separately supplied to a fluidized bed reactor of a circulating fluidized bed.  In the fluidized bed reactor, the gas velocity is adjusted to 2 to 10 m/s (empty pipe velocity), the mean suspension density is adjusted to 0.1 to 10 kg/m3, the temperature is adjusted to 700 to 1100°C, and the stoichiometric ratio of gas-purifying agent having a particle size dp 50 of 30 to 200 µm to polluant contained in the process exhaust gas or formed by the combustion is adjusted to 1.2 to 3.0, calculated as Ca:S.  The solids entrained by the gases from the fluidized-bed reactor are recycled to the fluidized bed reactor in such a manner that the quantity of solids circulated per hour in the circulating fluidized bed is at least 5 times the weight of solids con-tained in the fluidized bed reactor.  In a preferred embodi-ment, exhaust gas from a pellet-firing machine or a sintering plant, preferably from a region having a high SO2 concentra-tion, is used as an oxygen-containing gas and the oxygen-containing gas is supplied at such a rate that the resulting flue gas has an oxygen-content of 2 to 10 % by volume.

Abstract: Abstract Apparatus as provided for generating a condensed beam of light having a limited degree of scatter, or deviation, comprising light collimating means for providing a source of collimating light and light condensing means operatively connected to the collimating means, such as a truncated cone with a reflective inner surface, the condensing means providing a light beam output having a light divergence limited to about 30° or less.  The low divergence beam generating apparatus might be incorporated into larger dental apparatus which can be operator manipulated to provide different modes of light output, which modes include the condensed beam with and without a bandpass of visible wavelengths.  In practicing the method of this invention, particularly with respect to dental applications such as curing restorative materials placed in one or more teeth of a patient's oral cavity, the low divergence beam is directed at the teeth from a distance of about 1 cm, enabling reduced operator dependence in the process of curing the restorative materials.

Abstract: TITLE:  METHOD OF, AND APPARATUS FOR, MELTING SULPHUR     INVENTORS: Andrew W. Desynski and Andre Tucque ABSTRACT OF THE DISCLOSURE         A method of melting sulphur, in block form, uses a heating device having lower heating surfaces and means for withdrawing sulphur.  The device is positioned on a block of sulphur so that the heating surface(s) are inclined downwardly to a collection location spaced inwardly from sides of the sulphur block.  The heat is supplied to the heating surfaces to melt sulphur, and molten sulphur is withdrawn by the means for withdrawing it.  As sulphur is melted, the heating device is progressively lowered through the block of sulphur.  A corresponding apparatus having inclined heating surfaces is provided.  As the sulphur is melted so that molten sulphur runs down towards the collection location, the device can be used right up against the edge of a block of sulphur.

Abstract: Abstract An improved color picture tube has an inline electron gun for generating and directing three electron beams, a center beam and two side beams, along coplanar paths toward a screen of the tube.  The gun includes a main focus lens for focusing the electron beams.  The main focus lens is formed by two spaced electrode members, each having three separate inline apertures therein, a center aperture and two side apertures.  The improvement comprises each of the apertures in each of the focus lens electrodes having a shape that distorts a portion of the focus lens thereat, to at least partially compensate for an astigmatic effect within the tube that acts on an associated electron beam.  The side apertures in both of the electrodes are nonsymmetrical about axes that pass through the respective side apertures and are perpendicular to the initial coplanar paths of the electron beams.

Abstract: ABSTRACT A humidifier has an improved bottle wherein the water inlet and steam outlet are provided towards the top of the bottle and a drain outlet is located at the lower extremity of the bottle, a drain pipe being connected to the drain outlet and extending up the side of the bottle such that the upper end of the drain pipe establishes the static water level in the humidifier chamber of the bottle.  The chamber is also provided with ports in its top through which connections are passed to electrodes which extend vertically within the chamber such that current passes between the electrodes, via water in the chamber, to heat the water.  The impurity level of the water in the chamber is monitored by monitoring the current flowing between the electrodes and when the impurity level reaches a predetermined value the chamber is flushed by opening a water inlet valve for a predetermined period of time.  An electrical contact is also provided to detect a high water level of the chamber and when the water level drops below the high water level contact such that the contact continuously senses the absence of water for a predetermined fixed period of time, the inlet valve is opened until the high water level contact once again senses the presence of water.
