Abstract: Useless refrigerators or other commodities which contain or consist of polyurethane foam wherein the cells confine fluorochlorohydrocarbon gas are relieved of refrigerant and lubricant prior to being comminuted into 1 cm.sup.3 cubes or similar particles. The particles are classified in a suction chamber to segregate comminuted foam from metallic and/or plastic materials, and the particles of foam are thereupon ground and/or otherwise pulverized to a size in the range of 0.1 mm. This destroys the cells and releases the gas which is filtered, condensed and mixed with water prior to confinement in vessels.

Abstract: Discarded refrigerators, freezers and like cooling units are relieved of confined supplies of coolant and/or lubricant by transporting them onto a tiltable platform which attracts the cooling units by suction and tilts them until the freshly tapped portion of the normally closed circuit for coolant or lubricant is located at the lowermost point of the circuit. The lubricant or coolant can be evacuated by a pump by way of a conduit which is connected to a tapping tool and discharges into a vessel. Alternatively, the coolant or lubricant is caused to flow from the tapped circuit by gravity to gather in a vessel beneath the tiltable platform. The transporting system for cooling units can employ trolleys and winches with suction cups which lift discarded cooling units from the gathering point for discarded cooling units and remove cooling units from the platform when the lubricant- or coolant-evacuating operation is completed.

Abstract: A pharmaceutical composition is being described that contains pharmacologically acceptable magnesium compounds, etofylline, vitamin A and vitamin C. It is especially suitable for treatment of inflammatory changes of the bronchial mucosa.
