摘要:
Apparatus and method are provided for electric induction heating and/or stirring of a molten electrically conductive composition in a containment vessel with the apparatus being removably insertable in the molten composition. An induction coil embedded in refractory or a coating is submerged in the composition and used to heat and/or stir the molten composition either externally or internally to the refractory or coating.
摘要:
One or more sections of a solenoidal induction coil are moved relative to the surface of a strip passing through the coil as one or more parameters of the strip change to affect the impedance of the load circuit, while the output frequency of the power supply providing power to the coil via a capacitive element is changed so that the power supply's load circuit continues to operate at substantially resonant frequency.

An electric induction gas-sealed tunnel furnace and process are provided. The exterior of the furnace's enclosure that forms a closed tunnel region is surrounded at least along its longitudinal length by a gas-tight barrier chamber that can be filled with a barrier gas to a different pressure than the pressure of the process gas in the closed tunnel region of the furnace. The inductors used to induction heat strips or plates in the closed tunnel region can be positioned within or outside of the gas-tight barrier chamber around the longitudinal length of the closed tunnel region.
摘要:
An apparatus and process are provided for controlling the cross sectional temperature profile of a continuously moving workpiece with an induction coil assembly that provides for a combination of longitudinal and transverse magnetic flux field heating of the workpiece. The induction coil assembly includes means for laterally moving the workpiece in and out of the coil assembly without movement of the coil assembly.
摘要:
Single-use cosmetic article comprising at least one fibrous support extending substantially in at least one plane, and made of at least one material chosen such that: i) when the support is placed in contact with water at a first temperature T0, it at least partially shrinks and becomes elastic in at least one direction of the said plane, and such that ii) when the support is placed in contact with water at a second temperature T1, higher than the first temperature T0, it dissolves so as to become at least partially disintegrated.
摘要:
A device intended to reduce the risks of overexposure to harmful solar radiation. The device includes a detection arrangement, including at least one sensor sensitive to solar radiation, in particular UV. In addition, an arrangement is linked to the detection arrangement to generate a signal representing the quantity of radiation received by the detection means. An attachment arrangement is provided to attach the device to the head of a subject, such that the sensor(s) is (are) oriented in a substantially perpendicular manner to the vertical plane of the subject when the latter is active in the sun. The device is preferably configured in the form of a cap, with the detection arrangement arranged on a first visor intended to be positioned over the back of the individual's neck. The cap also preferably includes a second visor located opposite the first.
摘要:
The invention relates to a cooking utensil comprising a hollow bowl with a base and a side wall rising from the base, and including at least one fragile area. The bowl has a concave inner surface for receiving food, as well as a convex outer surface. The utensil is coated successively, from the bowl, with a hard base and a nonstick coating, which covers the hard base and includes at least one layer containing at least one fluorocarbon resin. The hard base has a layer that is at least broken at the fragile area. The invention also relates to a method for producing such a utensil.
摘要:
A brush for applying a powdered cosmetic composition, comprising: a tuft of synthetic hairs comprising at least two groups of hairs having, at their free ends, cross-sections of different surface area; and a handle supporting the tuft of hairs from a connecting portion of the hairs, characterized in that the groups of hairs have, in cross-section, the same surface area along their connecting portion.
