Ethylene glycol is prepared by a process in which ethylene oxide is extracted from an aqueous solution with near-critical or super-critical carbon dioxide. Thereafter an ethylene oxide-carbon dioxide-water mixture is contacted with a catalyst to form ethylene carbonate, which is then hydrolyzed to ethylene glycol in the presence of the same catalyst. The ethylene glycol is separated as product and...

The appts. is partic. intended to utilise low speed winds, and is of the type which comprises a rotor having a number of blades adapted to rotate about a parallel axis to the direction of the windflow. The blades are shaped and arranged to form an annular ring of blades bound externally by a tubular element and internally by a tapered element effective to duct the air impinging thereon toward said...

A long, thin annular belt-like channel is designed for use in sedimentation field flow fractionation. This channel, which may be contained in the rotor of a centrifuge, has a generally rectangular cross-section. It has an inlet positioned to introduce particulates (includes particles and/or macromolecules) approximately at the radial distance from the outer wall that is the equilibrium distance re...

The apparatus comprises a first apparatus part (8, 12) and a second apparatus part (16, 18) which is disposed on and extends outward from the first part. The second part is moveable with respect to the first part between an attracted position, in which it is extended to a predetermined extent, and a retracted position. in which it is extended to a lesser extent. The apparatus also comprises a sec...

An internal lining for ducts (C) is provided by introducing into one end of the duct an assembly (E) which comprises a sleeve (5) and an inflatable system (2) and which is provided with heating means for applying a sheath (1) impregnated with a resin against the inner wall of said duct (C).

A reduction ratio control for a continuously variable transmission is provided. In this control, a target value is changed to a new target value in response to deceleration after the motor vehicle has started decelerating, and the reduction ratio change is carried out in such a manner as to decrease a difference between an actual value and the new target value toward zero.

A continuous screw centrifuge has a rotating solid-walled drum 5 and a filter 1 which extends generally transversely across the drum to filter the liquid discharging therefrom. The filter may be an annular disc mounted either on the drum or on the differentially-rotating screw 4. Apertures 10 may allow liquid to bypass a clogged filter, and baffles 11, 12 separate the filtrate from the bypass liqu...
