Title: Method for treating and upgrading effluents containing metallic sulphates using an ammonia addition step
Inventor: MULLER PASCAL
IPC: C02F1/20
Filed: 2001-04-17
Abstract: The invention concerns a method for treating and upgrading effluents containing at least a metallic sulphate, characterised in that it comprises steps which consist in: adding at least a base to the effluent to precipitate the metallic ions in the form of metallic hydroxides Mea(OH)e; separating the precipitated hydroxide during a step of alkalinization of the rest of the effluent; adding to said effluent calcium hydroxide Ca(OH)2 so as to precipitate hydrated calcium sulphate CaSO4; and separating the calcium sulphate CaSO4 precipitated during the preceding step. Said method enables to obtain calcium sulphate (white gypsum) substantially free of metals and therefore capable of being upgraded and metallic oxy-hydroxides likewise capable of being upgraded.

Title: High tracking index liquid crystalline polymers and related applications
Inventor: COTTIS STEVE GUST
IPC: C08K7/00
Filed: 2001-07-05
Abstract: Excellent tracking index as well as flame-resistant properties are achieved with other desirable characteristics of LCPs in a resin composition consisti ng essentially of: a) a wholly aromatic polyester which is melt processible and  which displays anisotropy in the molten state; b) a non-conductive filler material having a diameter of less than about 3 m, with said non-conductive filler material being present in an amount sufficient to increase the comparative tracking index (CTI) rating of said composition to above 220 vol ts and render the composition non-burning. Optionally, an extraordinarily small  amount of non-volatile fluorescent brightener can be added to the resin composition. In combination with the non-conductive filler, the fluorescent brightener is found to surprisingly and significantly improve the flame- retardant property of the resin.

Title: A cooling arrangement for an integrated circuit
Inventor: ESPERSEN MORTEN
IPC: H01L23/473
Filed: 2002-02-14
Abstract: A cooling arrangement for one or more integrated circuits which are mounted in a socket on a printed circuit board and which each are cooled by a cooling element based on a compressor. The surface of each integrated circuit has arranged thereon a cooling element which is formed by an evaporator in the form of a housing (15) which has a lid with protruding cooling rods. Coolant is supplied to the housing (15) via a supply pipe (22, 23) that ends in an inlet stub (24) in the housing, which is constructed such that the coolant changes its direction, such as 90~, when entering the interior of the housin g. The coolant is returned form the housing via an outlet stub (25) which is concentric with the inlet stub (22). The supply pipe has a smaller diameter than the inlet stub (24) and the outlet stub (25), which means that cooling of the coolant and thereby of the cooling rods takes place in the housing, said cooling being transferred to the individual ICs. With a view to avoiding formation of condensate in connection with the cooling process, the housing is fixed against the printed circuit board according to the invention, a sealin g material, such as butyl, being arranged between the housing (15) and the printed circuit board (3). For additional sealing, a rear flange may be fixe d on the rear side of the printed circuit board in the area where wires are ru n to the IC, said rear flange being sealed with butyl against the printed circuit board.
