Abstract: Differential thermal growth between joined flanged members (30, 40; 50, 60) is accommodated by making proximate pairs of axially extending sawcuts (33, 33'; 63, 63') through the flange (32; 62) and into the casings to form elongated tabs which define sawcut springs (36; 66). By joining the flanged members at the location of some of the sawcut springs, the springs deflect to permit differential thermal growth. Additionally, the flanged members can be maintained in a centered position, even under conditions of thermal growth, by centering the member by means of a plurality of circumferentially spaced jackscrews (70) which engage the remainder of the sawcut springs.

Abstract: Le procédé consiste à préparer une suspension de tourbe de manière à libérer les fibres de tourbe du matériau d'origine. Les particules les plus grosses sont séparées dans une étape de déshydratation, et un matériau de fibre de tourbe ayant une teneur en eau désirée est obtenu. L'invention décrit un procédé dans lequel des particules colloïdales obtenues de la suspension de tourbe sont isolées de l'eau contenant le colloïde, en tant que sous-produits du traitement de la tourbe, et dans lequel l'eau du procédé est recyclée dans la suspension de tourbe. Ceci permet l'utilisation d'une installation mobile simple appropriée toute l'année durant, dans des tourbillères relativement petites, drainées que très superficiellement, ou des régions de tourbe dont l'exploitation était jusqu'à présent peu rentable. Les fibres de tourbe et le matériau colloïdal obtenu à l'aide du procédé ont une utilisation en tant que produits d'amélioration et de modification des sols, en tant que matériau de combustion, et dans la fabrication de carton et de filtres.
