Abstract: A separator holder structure for the quick loading of yarn would spools in dyeing machines, drying machines or other processing devices. The structure consists of a frame forming latticed tray which is divided internally into housings in each of which is secured, with the possibility of a limited vertical movement, a separator adapted to keep the yarn wound spools centered within the respective housing and to ensure hydraulic tightness between the vertically stacked elements in each column of spools when multiple structures are stacked. The possibility of movement of ht eseparators permits a quick stacking of the spools on horizontal layers, as the expedient allows the correct setting of separators, in individually loose manner, to ensure hydraulic tightness of same at the two ends of spools on which the yarn is wound.

Abstract: A heat exchanger is disclosed, comprising a shell housing a rotor. The rotor comprises a series of hollow bodies whose interiors are hydraulically connected to each other and which are secured to a shaft which is rotatably mounted in the shell. One liquid flows through the shell in contact with the exterior of the hollow bodies. Part of the shaft is hollow to permit flow through the shaft and the hollow bodies of a second liquid. Diaphragms are disposed in the hollow bodies to regulate the flow of fluid therethrough. The shell preferably comprises large diameter fittings. The second liquid is preferably dense and may comprise sludge, waste water, etc.
