Abstract: The invention relates to a connection arrangement for connecting two profiled elements in a seamless and aerodynamically smooth manner in order to form a profiled surface around which a laminar flow is possible. A first profiled element has a first fixing strip that extends towards the second profiled element, and the surface of the first fixing strip is lower than the surfaces of the profiled elements in the outward direction. Furthermore, the second profiled element has a second fixing strip which is molded on the inside and which is arranged below the first fixing strip, and the two profiled elements are rigidly connected to each other by means of the second fixing strip. A filler region that can be found below the connecting surface between the profiled surfaces and above the fixing strip surface is tilled with at least two layers of cured filling material. A method for filling the filling region with filling material and a device for carrying out the method are also claimed.

Abstract: The invention relates to a connection arrangement (30b) for connecting two profiled elements (32, 34) in a seamless and aerodynamically smooth manner in order to form a profiled surface around which a laminar flow is possible. A first profiled element (32) has a first fixing strip that extends towards the second profiled element (34), and the surface (44) of the first fixing strip is lower than the surfaces of the profiled elements (32, 34) in the outward direction. Furthermore, the second profiled element (34) has a second fixing strip (44) which is molded on the inside and which is arranged below the first fixing strip (36), and the two profiled elements (32, 34) are rigidly connected to each other by means of the second fixing strip. A filler region that can be found below the connecting surface (55) between the profiled surfaces (32, 34) and above the fixing strip surface (44) is tilled with at least two layers of cured filling material.

Abstract: A device provides a directed supply of tobacco ribs to a cutting tool. A vibrator conveyor conveys the tobacco ribs into the inlet area of a press conveyor disposed upstream of the cutting tool. The vibrator conveyor includes vertical partitions extending in the direction of tobacco rib transport. The intervals between the partitions are less than the average tobacco rib length. A device regulates the level of the tobacco rib flow transported between the partitions. Tobacco ribs can be precisely aligned in the axial direction prior to cutting, and can be transferred to the cutting tool without any loss of orientation.

Abstract: A coaxial filter cigarette with a rod portion having an inner core of material glowing substantially free of residue, in particular tobacco material, a sheath or wrapper for the inner core, an outer shell of tobacco and/or non-tobacco material coaxially surrounding the inner core or its sheath, respectively, a sheath or wrapper for the outer shell, and with a filter portion having a filter core, an air-impermeable sheath or wrapper for the filter core, a filter shell and a sheath or wrapper for the filter shell comprises a zone of the main heat source which is located in the inner core of the rod portion and a zone in which the major part of the aerosol reaching the mouth of the smoker is produced and which is located in the outer shell of the rod portion; the filter portion greatly reduces the combustion gases originating from the inner core of the rod portion and substantially reduces the smoke particles originating from the inner core, whereas the aerosol produced in the outer shell of the rod portion is i

Abstract: A device, for detecting a sufficient glue coating on a first surface of a paper strip to be adhesively bonded in a cigarette machine, includes a sliding plate having a plate surface engaging a second surface of the paper strip, opposite to the first surface, and over which the paper strip runs in a first direction. A plurality of capacitive sensors, for detecting presence of moisture in the glue coating, on the first surface of the paper strip, are directed toward the second surface of the paper strip, are mounted in recesses in the sliding plate and are arranged in a row extending transversely to the first direction. A control is coupled to the sensors for evaluating signals emitted from the sensors and for emitting a fault signal for controlling the cigarette machine when the moisture sensed in the glue coating is insufficient.

Abstract: A method and apparatus for process control in both the production of uniform material layers using vapor deposition, sputtering, chemical deposition, etc. and the treating of material layers. In particular, the process and apparatus are particularly useful in semiconductor fabrication where ion implantation or diffusion is used. A brief test signal of preset shape, frequency spectrum, or frequency sequence is applied at given time intervals to the material layer whose production characteristics need to be monitored. The measuring signal is applied to a digital evaluation circuit in a process control computer. The signal has various components whose time constants and/or conductivities are different from one another and which together are characteristics of the current flowing through the layer being monitored. In particular, the current flowing over the surface layer i.sub.1, the current flowing through particle houndary areas i.sub.3, and the current through homogeneous material ranges i.sub.
