Abstract: A flat sealing gasket includes an opening defined by a gasket edge and a sheet metal armor framing the gasket edge. The armor at least partially encloses an annular space which is situated radially inwardly of the gasket edge and is generally concentric with the gasket opening. Further, a graphite filling is accommodated in the annular space.

Abstract: A soft gasket material comprising an asbestos-free fiber material containing fibers and an organic binder, the soft gasket material being comprised of a fiber sheet containing at least three different intermixed types of fibers, namely (a) natural organic fibers, (b) synthetic organic fibers, and (c) at least one fiber type selected from mineral fibers and metal fibers, and being additionally comprised of powdered to finely fibrous fillers and at least one organic binder.

Abstract: A deactivatable security label comprising a low-coercivity strip and a strip having a high coercive field strength can be advantageously manufactured when the alloy of cobalt, nickle and/or iron is employed which exhibits a coercive field strength of between 20 and 50 A/cm given a remanence of more than one Tesla and when this strip is secured to a low-coercivity strip of amorphous material by means of spot welding.

Abstract: A soft substance gasket material preferably made of a metal reinforced fiber mat is impregnated with a silicone impregnating agent comprising a mixture of a polysiloxane having reactive hydrogen groups such as a polyhydrogen siloxane, an addition cross-linking polysiloxane such as a methyl vinyl siloxane, and cross-linking catalysts, preferably in the form of only one organic metal compound. In spite of having small quantities of addition cross-linking polysiloxane and cross-linking catalysts, the impregnated seals are not tacky after cross-linking, they are easy and inexpensive to manufacture, and they evidence improved functional characteristics such as improved resistance to hot media, temperature and aging when compared with seals impregnated with only one type of polysiloxane.

Abstract: A torque sensor has a magnetic foil which is wound and attached to a rotating shaft in strip form at an angle to the shaft axis of rotation, the magnetic strip being mechanically stressed dependent upon the torque acting on the shaft, and generating voltages in two secondary windings surrounding the magnetic strips. The voltages will be different due to different forces acting on the two strips, this being a measure of the torque acting on the shaft. The strips are formed from stamped segments cut obliquely from an amorphous tape which is cast with a profiled cross-machine cross section having regions of varying thickness. Such a tape can be manufactured using a nozzle having a correspondingly shaped orifice opening through which molten amorphous alloy is discharged onto a moving cooling surface.

Abstract: A sorter for paper pulp suspension including a rotationally symmetrical wire cage and a rotor supporting a plurality of vanes for rotating about the interior of the cage for moving suspension through the wire cage, the vanes being non-uniformly spaced. An annular pulp chamber surrounds the screen for collecting the pulp. A suspension outlet at the bottom of the pulp chamber receives the pulp from the pulp chamber. The pulp chamber extends axially beyond the lower end of the wire cage. An annular damping chamber surrounds the lower end of the pulp chamber and flow from the pulp chamber to the pulp outlet is past the damping chamber. The damping chamber develops a pool of the suspension in it. A pressurized gas cushion above the pool of suspension in the damping chamber controls the level thereof and damps the motion of the pulp in the pulp chamber.

Abstract: An impregnated, soft, flat sealing gasket and a method of manufacturing same which includes the steps of impregnating a fiber mat with a liquid, cross-linkable silicone impregnating agent which includes a cross-linking agent which forms radicals under the influence of heat; heating the silicone-impregnated fiber mat to cause at least partial cross-linking of the silicone impregnating agent; and irradiating the impregnated fiber mat with high energy radiation to cause cross-linking of the silicone impregnating agent present therein, whereby the silicone impregnating agent present in surface regions of the flat sealing gasket is cross-linked to a greater degree than obtainable by thermal treatment alone.

Abstract: A soft material, flat gasket having a release coating adhered thereto prepared by a process which includes: perparing a release coating composition which is a suspension including: from 69.5 to 93 parts by weight of an oil having a viscosity in excess of 100 m Pa.times.s and a fire point in excess of 230.degree. C., which oil is one of a mineral oil, a nonreactive silicone oil, and a mixture thereof; from 5 to 20 parts by weight of a polytetrafluoroethylene powder which has a particle size of less than 5.mu.; from 0.5 to 10 parts by weight of an aqueous latex; and from 0.5 to 2 parts by weight of a wetting agent; and applying the release coating composition by coating at least a predetermined portion of at least one surface of the soft material, flat gasket therewith.

Abstract: A method of making a flat gasket comprising a non-woven mat having opposite faces, including the steps of impregnating the mat with a polymerizable liquid impregnating agent and applying to at least one part of at least one mat face a coating containing a polymerizable polymer material. The coating is applied to the impregnated mat prior to polymerization of the impregnating agent. The impregnating agent and the coating are simultaneously polymerized in one operation.

Abstract: In the dispensing of gasoline into a tank used for the storage or transportation of gasoline wherein the gasoline displaces a gaseous mixture of air and gasoline, and said mixture is treated to a recovery step to separate said gasoline from said mixture, there is provided an improvement in the recovery step which comprises cooling said mixture to condense out the gasoline and water from the air thereby purifying the air, and then separating the water from the gasoline.

Abstract: A turbomachinery vane or blade with cooled platforms including provision for film cooling the inner and outer surfaces of the platform forward portion, including cooling fluid cavities in the platform on both the pressure and suction sides of the vane or blade airfoil for cooling this region of the platform by a combination of impingement, convection and film cooling, and a selective array of drilled holes extending through the platform trailing edge for convection cooling thereof.

Abstract: In the dispensing of gasoline into a tank used for the storage or transportation of gasoline wherein the gasoline displaces a gaseous mixture of air and gasoline, and said mixture is treated to a recovery step to separate said gasoline from said mixture, there is provided an improvement in the recovery step which comprises cooling said mixture to condense out the gasoline and water from the air thereby purifying the air, and then separating the water from the gasoline. One or two main heat exchangers can be employed depending on whether the system is operated continuously or not. A short regeneration time is made possible by the use of steam which expands the heat exchange tubes sufficiently to remove ice cleanly. An absorber using activated carbon is optionally employed in addition to the removal of the gasoline by cooling.

Abstract: The thickness of a thermoplastic kneading mass having a temperature of at least 40.degree.C in the feeding region of a roller gap, is measured by scanning in the said feeding region the zone of bare roll to kneading mass and kneading mass to rolling sheet with an infrared radiation receiver of high geometrical resolution defined by a diameter of the measuring field of from 0.5 to 3 mm with a measuring distance of from 0.2 to 3 m, recording the curve of thermal radiation and determining the thickness of kneading mass from the distance of the two points of discontinuity in the recorded curve of thermal radiation with consideration of the ratio of the scanning speed to the speed of registration.
