Abstract: "JET ENGINE NOISE SUPPRESSION SYSTEM"       Abstract of the Disclosure A  noise  suppression  system  for  use  with  a  jet aircraft engine having a plug support cylinder affixed to the engine, a tubular ejector shroud affixed to the engine and encompassing the plug support,  the shroud having a reduced  internal  diameter  adjacent  the  aft  end  and  a plurality  of   spaced   apart   blow-in  openings   formed circumferentially about the shroud forward end providing passageways  for  the  entrance  of  ambient  air  from  the exterior to the interior of the shroud.  A blow-in door is secured to the shroud for opening and closing each of the blow-in openings.  A translating plug is supported on the plug  support  cylinder  and  is  positionable  between  a forward position And an aft position and forms an annular exhaust nozzle between the exterior of the plug and the interior of the aft end of the shroud.   A daisy mixing nozzle is positioned within the shroud aft of the blow-in doors, the nozzle being configured of a plurality of lobes providing undulating interior and exterior surface.  When the plug is in the forward position the blow-in doors are open permitting ambient air to mix with exhaust gas from the jet engine and the nozzle area is enlarged producing lower gas velocities and lower sound intensities.   When the plug is in the aft position,  the blow-in doors are closed and the nozzle area is reduced providing higher gas velocities  for  increased  thrust  with some  increase  in sound intensity.

Abstract: In a process for producing coatings adhering to the surface while being removable, a treatment liquid is produced from PUR elastomers enabling a thermoplastic treatment by admixing a solvent. Said treatment liquid, fluid or viscous depending on the mixture ratio, is applied to the surface and forms after evaporation of the solvent a coating adhering solidly to the surface while being completely removable if required. Even in the case of a thin wall, said coating has an excellent tear resistance while being elastic and flexible. Its surface is absolutely tight and it provides a reliable protection against the mechanical effects and the like. It is preferably used for the reconditioning and the repair of tyres of motor vehicles, the necessary rubber envelope being replaced by the coating. Said coating may also be used as a protection against oxidation and adverse mechanical influences for the rough lower surface of the prefabricated rubber tread for the reconditioning of tyres of motor vehicles.

Abstract: A gas sensing unit designed to be protected against explosions and serving for the detection of combustible gases in an atmosphere, containing a gas sensor functioning according to the principle of catalytic oxidation or a semiconductor gas sensor. The gas sensing unit contains, within a housing, at least two mutually separated chambers or spaces. The one chambr is a compression-proof space and contains an electronic evaluation circuit for the gas sensor, the other chamber, which is a space structured to be protected against explosions, contains the gas sensor and a balancing element and is separated from the atmosphere by a sintered metal bushing or sleeve. A third explosion-proof chamber or space can be provided in the gas sensing unit for the purpose of connecting the lines or conductors. The gas sensor together with the balancing adapter forms an assembly or unit which can be pluggably arranged in the cover of the chamber containing the electronic system or hardware. With such type gas sensing unit it is possible to easily exchange the gas sensor at its erection site, without the need for having to open the compression-proof chamber containing the electronic components.

Abstract: A bottle cap of the tear-off type, particularly an easy-to-open cap for wide mouth bottles, in which a central top wall which covers the top portion of the mouth of the bottle is connected to a lateral band which surrounds the opening of the neck of the bottle and is bent under the edge of the neck to grip the cap, and a tear-off tab, bounded by one or more score lines, extends from the top wall through the lateral band and an angular sealing is interposed between the mouth of the bottle and the top wall and the lateral band. The angular sealing is bonded to the undersurface of the central top wall at a bond area inside the score line or lines, whereby, when the cap is broken by lifting the central top wall by means of the tear tab, the angular sealing is lifted with the central top wall in one piece and slips off from underneath the lateral band thereby freeing or loosening the lateral band from the mouth of the bottle.The sealing can also be bonded to the tear tab at the area bounded by the score line or lines towards the lateral band, to make the lifting of the sealing itself along with the central top wall easier, without breaking it.
