A heat exchanger comprises an external pipe 5 reinforced with an inner, slit pipe 11 and a concentric and radially-spaced inner pipe 1 through which a hotter medium is conveyed to a mixing chamber 3 to which the cooler medium is admitted from an inlet 2 in the pipe 5. The mixture passes to an outlet 4 in countercurrent flow to the hotter medium over the outer surface of the pipe 1 which forms a thermally conductive wall. The wall is formed by at least two concentric pipes, each of which having a slit to absorb thermal expansion which may be longitudinal or helical and so positioned as to be out of register with each other. A coil spring 10 retains the sleeve 11 in the region of the outlet zone 9 of the mixing chamber 3 to protect the external pipe 5 from localized thermal shocks from the mixing process.

Inventor: SABELSTROM JAN
IPC: B42D3/00
Filed: 1997-11-11
Abstract: According to one aspect, the invention relates to a method of stacking covers for the fabrication of booklets. Each cover includes two cover sheets and an interconnecting spine. Applied to the inner surface of the spine is a binding device that includes a binding agent. The covers are mutually stacked with the inner surface of the spine of one cover lying against the outer surface of the spine of an adjacent cover. According to the invention, a deactivatable separating device is provided between the binding agent and the outer surface of the spine of an adjacent cover, so as to prevent adhesion between the spines of respective covers. According to another aspect of the invention, a cover of this kind is provided with a binding device that includes a binding agent (104) and a separating device (105) disposed on the surface of the binding agent that lies remote from the spine (103), this separating device preferably having a form of woven material affixed to the binding agent (104). The invention also comprises a method of producing a booklet with the use of the inventive cover. According to the inventive method of fabrication, the separating device is deactivated at the same time as the binding agent is activated and a sheet bundle is moved in towards the spine of the cover.
