Abstract: L'invention concerne un récepteur de chaleur solaire concentrée monté sur une tour afin de recevoir de l'énergie thermique solaire concentrée en provenance d'un réseau de réflecteurs solaires à concentration. Le récepteur comprend un réseau monocouche de tubes conçus pour transporter un fluide de transfert de chaleur, tel que du sodium, et délimitant en association une surface découverte de réception d'énergie thermique solaire concentrée. Le réseau de tubes comprend un collecteur d'entrée de fluide inférieur en communication avec un conduit d'entrée, et un orifice de sortie de fluide supérieur en communication avec un conduit de sortie. Les tubes sont agencés selon une configuration en serpentin et délimitent un circuit d'écoulement de fluide principalement transversal et vers le haut. Le récepteur comprend un couvercle thermiquement isolant mobile entre une position ouverte et une position fermée dans laquelle la surface de réception d'énergie thermique solaire est recouverte afin de bloquer ou de réduire l'incidence du flux solaire sur les tubes ou de réduire la perte de chaleur du réseau de tubes lorsqu'ils ne sont pas en état de fonctionnement.

Title: Method of metalating unsaturated polymers
IPC: C08C19/42
Filed: 1969-03-14
Abstract: A polymer containing olefinic or aromatic unsaturation is reacted with an organolithium compound and a compound of an alkali metal other than lithium in which the metal is joined to an oxygen, sulphur or nitrogen atom. The polymer may be a " live " alkali metal compound catalysed polymerization product or it may have been deactivated. Suitable polymers include polybutadiene, polystyrene, polyisoprene, butadiene-styrene, butadiene-isoprene, isoprene-isobutylene copolymers and ethylenepropylene terpolymer. Alkali metal alkoxides, sulphides, amides or hydroxides may be employed as cometalating agent. The metalated polymers may be after-treated (a) with carbon dioxide to introduce carboxyl groups, which may be reacted successively with glycols and diisocyanates to give polyurethanes, (b) by reaction with ethylene oxide to give polyols, (c) by graft polymerization of monomers, and (d) by reaction with polymers containing halogen groups. In examples butadiene is homopolymerized in the presence of n-C 4 H 9 Li and either the " live " polymer or the neutralized " dead " polymer is treated with n-C 4 H 9 Li/t-C 4 H 9 OK and in some cases the polymers deactivated and treated with Si(CH 3 ) 3 Cl, while in others the metalated polymer is reacted with styrene.
