  • Publication number: 20140355968
    Abstract: The present invention relates to an electrothermal system which comprises at least one electrothermal equipment used to emit infrared radiation, a control unit used to control the operation of the electrothermal equipments. By using the control unit, some specified electrothermal equipments can be enabled to heat up some specified regions while the other electrothermal equipments will not operate. The present invention can reduce power consumption for only heating up demanded local regions and improving efficiency of electricity utilization.

  • Publication number: 20140314396
    Abstract: The present invention proposes an electrothermal element which comprises a substrate, a reflective layer, an electrothermal layer, and an auxiliary layer. The electrothermal layer can emit infrared radiation which is reflected by the reflective layer and enable infrared radiation emitted from one side of the electrothermal element. The auxiliary layer can increase the thermal uniformity of the electrothermal element and also convert the thermal energy of the electrothermal element itself into infrared radiation. It not only improves overall infrared emissivity of the electrothermal element but also reduces the temperature of the electrothermal element. This invention offers an effectively and rapidly warming up solution at selected local regions, no oxygen consumption and fan noise problems, and the electrothermal element can replace the traditional ceiling or be mounted directly on the wall, to solve the disadvantage of requiring space of the conventional electric heating device.

  • Patent number: 5470553
    Abstract: A method for separating aluminum, cobalt, and nickel ions contained in a sulfuric acid aqueous solution comprising the steps of (a) contacting a first water-immiscible organic solution containing a first extractant with the sulfuric acid aqueous solution for a period of time to selectively extract the Co ions into the first water-immiscible organic solution so as to obtain a Co-containing first organic phase and a first raffinate aqueous phase containing substantially no Co ions; (b) separating the Co-containing first organic phase from the first raffinate aqueous; (c) contacting a second water-immiscible organic solution containing the first extractant and a second extractant with the first raffinate aqueous solution for a period of time to selectively extract Ni ions into the second water-immiscible organic solution so as to obtain a Ni-containing second organic phase and a second raffinate aqueous phase containing substantially only Al ions; (d) separating the Ni-containing second organic phase from the se
