The invention relates to a synthetic soap which comprises a binder consisting of a mixture of one or more glycols, one or more alkali salts and one or more higher fatty acid derivatives having from about 12 to about 22 carbon atoms. Said binder may as well consist of a mixture of one or more glycols and one or more alkali soaps of one or more higher fatty acid derivatives having from about 12 to about 22 carbon atoms. The glycols used are preferably chosen from the group consisting of the lower glycols and the lower polyglycols.

Method for the closing of bags by means of clips (7), which clips are first formed into a U, then that the U-shaped strips are joined with each other in such a way that the form a gully. The preference the clips are fastened onto a adhesive tape (8). By rolling up into a roll the row of clips, this roll can be placed into a device, which device includes a frame, that turnable on a horizontal axis (3), is fastened to an undercarriage (2) which frame can swing around or hinge on an axis and that in, on or onto the frame the row of clips can be placed and that the row of clips can then by means of pulling means be guided by a guidance means (9, 10) past a folding station. By placing the bag at the folding station and pressing on the frame the bag will be closed with a clip by the help of two hamershaped members, which, turnable on an axis near the end of the handle, are fastened to the frame.

The invention relates to a heat extractor for the recovery of heat from flue gases, such as the products of combustion from a central heating furnace, which heat extractor comprises a first impeller (2) or blower and a plurality of parallel tubes (1), around which a stream for example fresh air generated by the first impeller (2) flows in a direction transversely to the longitudinal axes (3) thereof. In the flue gases of a central heating system energy is lost as the flue gases are blown off in the free air as they still contain heat. By the use of tubes of a rectangular cross-section and a second impeller (4), which suck the flue gases through the tubes (1), the flue gases can be cooled down to room temperature.
