Abstract: Oil-injected screw compressor installation including a frame or underframe (5 2), a screw compressor element (3), electrical cabinet (6), oil separator vessel (5) and an air-cooled cooling module (8), with as characteristic that on one side (2a) of the frame (2), the screw compressor element (3) is placed horizontally and with the electrical 10 cabinet (6), the oil separator vessel (5) and the aircooled cooling module (8) being placed on the other side (2b) of the frame (2), with the cooling module (8) being placed such that this is perpendicular to the compressor element (3) and the air (9) sucked in by the cooling module 15 (8) will flow between the electrical cabinet (6) and the cooling module (8).

Abstract: A canopy for a compressor or generator installation comprising a chassis (2) with—a base plate (3) comprising a body with a mounting surface bounded by a polygonal peripheral edge (4); and—a mounting frame (5) containing this base plate (3) and going around the peripheral edge (4); whereby the canopy (1) further comprises a number of corner stays (6), whereby each corner stay (6) is provided with a mounting end which is configured to be mounted onto the chassis (2), whereby at each corner of the peripheral edge (4), at least one corner stay (6) is mounted with its mounting end onto the chassis (2), whereby each corner stay (6) in a mounted state extends from the mounting surface of the base plate (3) in a direction essentially perpendicular to the mounting surface and outwards from the body of the base plate (3), and whereby each corner stay (6) in a mounted state has a free end which is opposite to the mounting end of this corner stay (6) and which is not mounted onto the mounting surface; and whereby the ca

Abstract: Polymerisation catalysts and systems comprising said catalysts for polymerising carbon dioxide and an epoxide, a lactide and/or lactone, and/or an epoxide and an anhydride. The catalyst is of formula (I): Wherein M1 and M2 are independently selected from Zn(II), Cr(II), Co(II), Cu(II), Mn(II), Ni(II), Mg(II), Fe(II), Ti(II), V(II), Cr(III)-X, Co(III)-X, Ni(III)-X, Mn(III)-X, Fe(III)-X, Ca(II), Ge(II), AI(III)-X, Ti(III)-X, V(III)-X, Ge(IV)-(X)2 or Ti(IV)-(X)2. R3A is different from R3B; and/or at least one occurrence of E3, E4, E5 and E6 is different to a remaining occurrence of E3, E4, E5 and E6. A ligand, a process of asymmetric N-substitution of a symmetrical ligand and a process for the reaction of: (i) carbon dioxide with an epoxide; (ii) an epoxide and an anhydride; and/or (iii) a lactide and/or a lactone, in the presence of a catalyst is also described.
