Abstract: The present invention relates to-a process and a device for the continuous manufacture of a polymer of an aromatic alkylene monomer e.g. styrene comprising a bulk polymerisation of the monomer and a devolatilization of the resulting polymer in at least two successive steps so as to separate the polymer from the unreacted monomer and the oligomers formed during the polymerisation. The process comprises conveying a first gas stream resulting from the first step of the devolatilization into a first zone Z1 for direct condensation and fractionation, removing a gas stream G1 comprising essentially the monomer from the top of Z1, and removing a liquid stream L1 rich in oligomers from the bottom of Z1, a portion of L1 being taken, cooled and then returned into Z1.

Abstract: A cooling system for an electric motor includes a cooling duct formed between a cooling jacket and a separate component surface. The separate component surface may define at least a portion of a wall of the cooling duct. The cooling duct may be configured to direct a cooling liquid along at least a portion of the separate component surface and draw heat from the electric motor. An inlet port may be in fluid communication with the cooling duct. The inlet port may be configured to receive the cooling liquid and to introduce the cooling liquid to the cooling duct. An outlet port may be in fluid communication with the cooling duct.

Abstract: An anti-skid brake control system comprises a cylinder casing having a first chamber connected with a master cylinder and a second chamber in communication with wheel brake cylinders, a cut-off valve disposed within the first chamber for selectively interrupting fluid communication between the first and second chambers, and a hydraulic capacity controller including a plunger axially reciprocable within the first chamber and operatively engaged at its both ends with the cut-off valve and a piston reciprocable within a vacuum servo-motor, the plunger being retracted by the piston to activate the cut-off valve and thereafter to increase the capacity of the second chamber to decrease the braking pressure applied to the wheel brake cylinders.
