    Abstract: Apparatus for the continuous manufacture of endless foams from prefoamed particulate plastics capable of further expansion. The plastics are passed through a heating zone and a cooling zone by means of belts defining a channel and composed of transverse strips of alternately gas-permeable and gas-impermeable materials of equal thickness. This form of the belts produces better grades of foam at higher output rates on account of the more intense and more uniform steaming achieved. The foams produced are suitable, for example, for use as insulating materials in buildings and for packaging purposes.

    Abstract: A protective jacket, in particular for recording media, preferably magnetic films, is provided with at least one stiffened region in the immediate vicinity of the read/write area, thus permitting more thorough cleaning of the recording medium and smoother running of the latter. Stiffened region(s) can be produced economically by printing on strips of ink.

    Abstract: - 10 - O.Z. 0050/40315 An apparatus for washing out photopolymer printing plates by means of solvents, drying the printing plates and recovering the solvents, a conventional washout station and a conventional drying station being connected to a solvent recovery means integrated in the drying station, which consists of the following parts: a hermetically sealing drying chamber for the printing plates, having an adjustable hood (15) and stationary panel (16), with panel heaters (18a, 18b) inserted in the hood and panel, a system which is connected to the interior space formed when the drying chamber is closed and which consists of a heat exchanger (25) for cooling the solvent vapor/air mixture, formed by drying the printing plates in the drying chamber, and condensation of the solvents, a solvent separator (26) for separating off the liquefied solvents, a vacuum pump (27) and a buffer vessel (33) for sucking up the solvent vapor/air mixture and compressing the solvent vapor/air mixture, a heat exchanger (28) for increasing the temperature of the air circulating in the system, two three-way valves (31, 32) and connecting pipelines from the drying chamber via the individual units and back to the drying chamber.
