Abstract: In the case of a flat metal packing, such as, in particular, a cylinder head gasket for internal combustion engines, consisting of a laminate having at least three sheet-metal plates one on top of the other, the means for increasing tightness at the through openings consist of annular polymeric layers applied, preferably by screen printing, all the way round the openings for liquid and all the way round the openings of the combustion chamber, to the core sheet, preferably on both sides, making it possible to produce the packing with an improved sealing quality in a simple and economical manner and, especially with its improved seating properties and freedom from the need for retightening, to use it in combustion engines having relatively high compression pressures. <IMAGE>

Abstract: The analog signals from the reading means (12) and the plural number of detecting means (20, 24) provided in the facsimile communication apparatus (11) of the invention are selected sequentially by the selective connecting means (25) for connection to the analog/digital conversion means (29) and converted into digital signals. This eliminates the necessity of connecting individual analog/digital conversion means (29) to the reading means (12) and the plural number of detecting means (20,24) and enables miniaturization of the apparatus construction by reducing the number of parts used. Moreover, the miniaturization of the construction can be further promoted because of the fact that the parts reduced are the parts for processing analog signals.

It contains material (38) which is softer than the basic rubber material (34) of the roller. Shallow pockets (48,50) are formed along the surface, and the ink (45) in the gap (46) between the rollers is forced inwards towards the centre of the roller.

Abstract: A process and apparatus for manipulating boundless data streams in an object oriented programming system (11) provides a stream class of objects which includes as attributes an ordered list of object references to select­ed ones of the data objects stored in the data storage device (14). Methods for manipulating the object include move to first. move to last. move to next and move to previous which provide a bi-directional data stream. The data appears to the user as though it resides entirely in memory, even though it does not. The stream class imple­ments a "sliding window" in an object oriented programming system which permits manipulation of any number of lists of virtually unlimited size when remaining within the physical limitations of finite storage.

Abstract: A supporting beam 4 bears a hollow, box-shaped carrier 11, on which there is situated, substantially tangentially with respect to the circumferential surface of an associated guide roll 2, a presser surface 5 for the paster strip. A slot 6 for holding the paster strip A is situated perpendicularly to the presser surface on the box-shaped carrier 11. A considerable part of the paster strip A, from which the cover film has been removed, projects from said slot. Blowing means or blowing channels 9 with blowing ports 10 bend upwards that part of the paster strip projecting from the slot 6, so that, as the supporting beam 4 moves nearer to the guide roll 2, said part of the paster strip lies practically against the presser surface 5. In this way, the paster strip can be fastened on the end of the web, which is wrapped over the guide roll 2.
