APPARATUS FOR CONTINUOUS THERMAL SEPARATION OF A MULTI-COMPONENT SUBSTANCE
A separation apparatus for continuous thermal separation of a substance is fed into a treatment chamber. The substance includes two or more components where at least one of the components is evaporable at an evaporation temperature (T.sub.e). The separation apparatus includes a vessel including a vessel wall with an inner surface enclosing the treatment chamber having a length I.sub.C, a height H and a width W, a substance inlet for feeding the substance into the treatment chamber, a first outlet for releasing non--evaporated parts of the substance from the treatment chamber, a second outlet for releasing evaporated parts of the substance from the treatment chamber, and a rotary mechanism. The rotary mechanism includes a rotatable axle arranged within the treatment chamber having an orientation directed along the treatment chamber's length L and a mixing device fixed to, and extending perpendicular from, the rotatable axle. A radial outermost part of the mixing device includes a plurality of radially separated mixing protrusions, a rotary drive operatively connected to the rotatable axis, and a heating device arranged outside the treatment chamber. The heating device is configured to transfer thermal energy to a minimum peripheral volume (Vp) of the treatment chamber via the inner surface. The minimum peripheral volume (V.sub.p) is defined as a volume between the inner surface and outer radial boundaries of the mixing device. The mixing device includes a plurality of rotary discs fixed with axial offsets to the rotatable axle. The heating device and the rotary drive are configured such that, when both the heating device and the rotary drive are operated at their respective operational input powers (P.sub.hd, P.sub.rm,), a resulting operational temperature (T.sub.op) is obtained within at least part of the minimum peripheral volume (V.sub.p) which is equal or higher than the evaporation temperature (T.sub.e).
Air bleeder and method for bleeding air
An air bleeder includes a branch, a lubricant supply conduit, and a return conduit. Lubricant stored in a tank is to be supplied to a valve provided in a machine tool via the lubricant supply conduit. The lubricant supply conduit includes a first supply conduit, and a second supply conduit. The first supply conduit connects the branch and the tank. The second supply conduit connects the branch at a first connecting position and the valve. The return conduit connects the tank and the branch at a second connecting position higher than the first connecting position in a height direction along a height of the air bleeder to return lubricant to the tank and to remove air from lubricant in the lubricant supply conduit.
Process and facility for recovering methoxypropanols from an aqueous stream
A process can be used for recovering 1-methoxy-2-propanol and 2-methoxy-1-propanol from an aqueous effluent stream by liquid-liquid-extraction, followed by extractive distillation, distillation of methoxypropanols from the extraction solvent, and distillative separation of the methoxypropanol isomers. Recovered extraction solvent is recycled to the extraction and extractive distillation. Heat transfer from recovered extraction solvent to the extract fed to the extractive distillation reduces energy demand of the process. A facility for this process contains a countercurrent extraction column, an extractive distillation column, a solvent recovery distillation column, an isomer separation distillation column, and a heat exchanger for transferring heat from recovered extraction solvent to the extract fed to the extractive distillation.
Automated link chain cleaning and lubricating system
A link chain cleaning and lubricating device, and lubricants for use therein.
Apparatuses for wind turbine blade railroad transportation and related systems and methods
A tip bolster (32) for supporting a wind turbine blade (40) on a railcar (14) includes a clamp (360) including first and second clamp arms (364, 366) having first and second jaws (384, 386), respectively, and supporting a pliable saddle (394) extending therebetween, the pliable saddle (394) being configured to support a portion of the blade (40) interposed between the first and second clamp arms (364, 366) and to conform to an exterior surface thereof.
Energy conservation using active demand stabilization
Some embodiments include electric power demand stabilization methods and systems that may include measuring the power draw of a plurality of controllable devices; determining a rolling average power draw for the plurality of controllable devices over a period of time; measuring an instantaneous power draw of the plurality of controllable devices; and calculating a power budget comprising the difference between the instantaneous power draw and the rolling average power draw. In the event the power budget is positive, increasing power to at least a first subset of the plurality of controllable devices. In the event the power budget is negative, decreasing power to at least a second subset of the plurality of controllable devices.

WATERJET CUTTING APPARATUS AND RELATED METHODS
Waterjet cutting apparatus and related methods are disclosed herein. An example apparatus includes a tank defining a volume to contain a fluid therein, a fixture extending from the tank, and a tube extending from the tank, the tube to isolate the fixture and a part supported by the fixture from turbulence of the fluid disposed in the tank.
Method for extruding and labelling a cylindrical product
The method for extruding and labeling a packaging tube comprises the following successive steps: a) forming a partially or totally tubular label from a film in a shaper; b) inserting the label into a calibration element; c) extruding a tubular body at the concave-face side of the label in an extrusion head; d) bringing the outer face of the extruded tubular body into contact with the concave face of the label. In the method, the label comprises at least one layer of which the melting temperature is at least 20° C. higher than the melting temperature of the extruded tubular body. A first pressure difference is formed in the extruded tube with an air jet.
