Title: Method of removing toxins from fly ash
Inventor: XU YOUTIAN
Filed: 2017-12-14
Abstract: METHOD OF REMOVING TOXINS FROM FLY ASH OF THE DISCLOSURE A method for disposing of fly ash. After the fly ash has been processed using the method contained herein, this fly ash can be disposed of more easily because of the reduced toxicity of the final product. Also, this converted fly ash may be recycled and used as a material or aggregate in concrete. The method includes the treatment of dioxins found in fly ash found in waste incinerator flue from waste incineration power plants which includes collecting the fly ash, putting the fly ash into a hermetic device and treating the fly ash through various heating steps and thereafter lowering an environmental temperature in the hermetic heating device, which results in a significant reduction of dioxins in the fly ash.

Title: Reeling device for a sheet metal strip
IPC: B65H19/28
Filed: 1986-02-28
Granted: 1987-08-25
Abstract: A reeling device for a sheet metal strip 4 consists of a reeling mandrel 1 with a receptacle 5 for the strip start 3 and of a drive 2, connected to a control arrangement 11, for the reeling mandrel 1. In order to make the strip start 3 run onto the reeling mandrel 1 in the area of the receptacle 5, the control arrangement 11, which is connected to a speed sensor 13 for the strip start 3, controls the mandrel drive 2 according to a revolving speed for the reeling mandrel 1 corresponding to the run-in speed of the strip start 3, a detector 14 for the strip start 3 being mounted upstream of the reeling mandrel 1. A computer 10 connected to the control arrangement 11 determines the rotation angle for the reeling mandrel 1 to the time of impact of the strip start 3 on the reeling mandrel 1 from the values available when the detector 14 responds, and provides it to the control arrangement 11 as a desired value for a desired/actual value adjustment. <IMAGE>

Title: Chromium-containing low-cure coating composition
IPC: C23C22/24
Filed: 1988-02-03
Abstract: A coating composition is now provided which can have a great number of desirable coating characteristics, when the composition is applied and cured on a metal substrate. Moreover, the coating composition has applicability to a great variety of metal substrates. Such substrates include base metal such as steel as well as metal coated substrates such as zinc electroplated steel. Furthermore, the coating compositions can be useful when applied to substrates sensitive to elevated cure temperature, e.g., annealed steel. In one important aspect the composition can contain hexavalent-chromium-providing substance in mixture with cobalt compound. Particulate metal may be present in the compositon. A composition furthermore most desirably contains a special organic acid/alcohol reducing agent combination for the hexavalent chromium. The composition can provide a low-cure coating on a metal substrate, which can then translate into higher production line speeds as when used for coating of metal coils.

The pin 5 and recess 4 each have a groove 7, 6, respectively, and a conical tapering 10 and 9, respectively, by which means two annular channels are formed into which O-rings 8, 11 are inserted. By virtue of the fact that the second O-ring 11 lies between conical surfaces, it can take up forces and deform both in the axial direction and transverse to the axial direction. A centring effect is also obtained. <IMAGE>
Patent CH-655414-B (CH)
IPC: H03K17/95
Filed: 1981-07-17
Abstract: A method of using the temperature coefficient of the copper resistance of an oscillating coil to compensate for the temperature coefficient of the quality factor of the same oscillating coil. To this end, a voltage proportional to the copper resistance of the oscillating coil is generated across the oscillating circuit. The oscillator according to the process comprises an oscillating coil which comprises a high frequency litz wire. In order to access the copper resistance of the coil one of the litz wires is separated from the other wire at a first terminal of the coil and separately connected to a second terminal of this coil. From this second terminal, the coil is seen as a bifilar coil. A constant alternating current source is connected to the second terminal in order to generates across the oscillating circuit a voltage proportional to the copper resistance of the coil. The oscillator is preferably used for proximity switches having relatively large switching distance.
