The first base and the second base have at least one pair of a first connecting portion and a second connecting portion that are male and female connecting portions and connected in a snap-fit manner, so that the first base and the second base form the whole base. A lower end of the heat supply tube is mounted to the first base. The object support is mounted to an upper end of the heat supply tube. The heating device is configured to supply hot air to the heat supply tube.

A painting facility 1 includes a painting chamber 3 in which a spray painting operation is effected on a painting object W, an air supplying chamber 2 configured to supply air into the painting chamber 3 via an air supplying section 4a, 4b provided in a ceiling portion 30 of the painting chamber 3, and an air discharging chamber 5 configured to suction air and uncoated paint mist present in the painting chamber 3 via a floor discharging section of the painting chamber 3, two air supplying sections 4a, 4b are disposed in left-right symmetry relative to a position of the painting object W in a width direction of the painting chamber 3 as the center therebetween. Air is released in a radial form from an outlet portion 40 of each one of the two air supplying sections 4a, 4b.

Provided is a magnetic separator in which even when content of a magnetic sludge in a liquid to be treated increases, recovery performance of the magnetic sludge is less likely to degrade and a malfunction of the device is less likely to occur. A part of an outer peripheral surface of a magnet drum is immersed in a flow of the liquid to be treated containing the magnetic sludge. A removing mechanism removes the magnetic sludge on the outer peripheral surface of the magnet drum from the outer peripheral surface of the magnet drum. A magnetic sludge containing information acquisition device acquires magnetic sludge containing information relating to a content of the magnetic sludge contained in the liquid to be treated. A control device changes a magnetic sludge removal capability of the magnet drum depending on the magnetic sludge containing information acquired by the magnetic sludge containing information acquisition device.

To provide a servo controller for an industrial machine allowing construction of a system achieving more excellent power efficiency than a conventional system. A servo controller includes: a driving motor that drives an industrial machine; a load detecting unit that detects a load on the driving motor or the amount of power consumed by the driving motor; a buffer motor that feeds regenerative power to the driving motor on the basis of a result of the detection by the load detecting unit; and a base speed setting unit for recovering the buffer motor to a second base speed set to be lower than a constant first base speed preset for the buffer motor and applied before the regenerative power is fed to the driving motor after the buffer motor is decelerated from the first base speed and the regenerative power is fed to the driving motor.

The invention relates to a method for the treatment and utilization of waste liquor containing at least polyester degradation products and originating from an alkaline pulping process for the extraction of cellulose raw material from blended textile waste which contains at least a cellulose component and a polyester component. In order to make the method environmentally friendlier and more resource-efficient, it is proposed that the method comprises the following steps: the evaporation of water from the waste liquor in order to precipitate the polyester degradation product from the waste liquor and to obtain a two-phase mixture having an aqueous phase and a solid phase including the polyester degradation product, b) the separation of the solid phase from the liquid phase, and c) the thermal/energetic utilization of the solid phase.

An analysis method and apparatus are disclosed for analysing an absorption filtering medium that filters volatile organic substances in a process gas in a plant for dehumidifying polymer granules, with a fan that generates a flow of gas through the S filtering medium, an analyzer of the total concentration of the organic carbon, a sensor to detect the pressure downstream of the filtering medium, in which the saturation state and/or the absorbent capacity and/or the deterioration over time of the filtering medium is determined by a comparison of the measured concentrations of total organic carbon in the flow of gas upstream and downstream of the filtering medium.
