Abstract: DRAG-REDUCING NACELLE                   ABSTRACT OF THE DISCLOSURE                  A Wing-mounted gas turbofan engine is provided with an exhaust system that reduces airflow drag during subsonic aircraft flight peration. The system reduces drag by turning the engine bypass exhaust stream away from the underside of the airplane wing to lessen its tenddency to reduce air pressure under the wing. Low pressure below the airplane wing has a detrimental effect on wing lift which, in turn, causes greater airflow drag. The exhaust system construction lessens its pressure lowering influence by first inwardly curving the exhaust system exit to turn the bypass flow away from the airplane wing; second, by determining the location of a nozzle throat within the bypass stream to control exit exhaust pressure so as to match outside air pressure and third, by decreasing the diameter of a portion of the engine nacelle just downstream of the bypass exhaust steam exit to provide a flow region for the exhaust that is further from the airplane wing.

Abstract: METHOD AND MEANS FOR REMOVING                  BINDER FROM A GREEN BODY          ABSTRACT OF THE DISCLOSURE   The disclosure relates to a method of binder removal from a green body before sintering or the like wherein the green body is placed in a pressure chamber wherein the pressure is raised to a level above the vapor pressure of the binder in the green body at the ambient temperature within the pressure chamber.  Where several binders are utilized simultaneously, the pressure within the chamber is maintained higher than the vapor pressure of the lowest of the binders then in the green body at the temperature within the green body.  Under these conditions, the binder or binders will turn to a vapor, will follow the normal laws of evaporation and diffusion and diffuse out from the green body into the surrounding environment within the chamber.         The binder can subsequently be removed from the chamber in conventional manner.

Abstract: ANIMAL LITTER AND METHOD OF PREPARATION                ABSTRACT OF THE DISCLOSURE        The animal litter comprises a litter of paper mate-rial that contains a pheromone-like attractant substance which makes the litter attractive to animals seeking a place to defecate and/or urinate.  The litter material is pelletized to give the litter a consistency comparable to that of fine gravel.  The pellets formed from the litter material hydrate slowly but positively and are disposable in water.  The density of the pellets is such that they retain their structural integrity on hydration.  The pellets are formed from ground paper having a low clay and mineral content which has been moistened with sufficient water to hold the particles together but not so much as to cause the pellets to feel moist.  An acid salt may either be added in the water or as a dry powder to the ground pa-per.  This salt carried by the water in the pellets neu-tralizes the animal urine (and the ammonia-like compounds formed from it) while maintaining the pH of the litter at a level acceptable to the animals.  A pheromone-like attrac-tant substance is added to the pellets either with the water or by spraying it on the finished pellets.  A further step comprises compacting the saturated, ground paper into pel-lets having the previously enumerated properties.

Abstract: ABSTRACT            HIGH CAPACITY OIL RECUPERATORS FOR DE-POLLUTION IN ROUGH WATERS, The invention relates to a high capacity oil recuperator for use in rough waters, associated to a fixed platform or to a de-polluting ship.                 Said recuperator consists of a submerged assembly composed of a cylinder of vanes rotating inside a stator of which the configuration induces and maintains in the liquid mixture sucked a localized vortex which is not associated to the flow and in which the oil concentra-tes immediately under the effect of a strong centrifugal acceleration. A pump working in connection with the stator sucks in the oil for storage purposed. The energy communicated to the rejected cleaned water can be advantageously used for propelling and manoeuvering the ship or platform.                  The invention rinds an application in the production of skimming crafts of all capacity used for the de-pollution of rough waters, in harbours, river, estuaries, and at sea.

Abstract: Abstract of the Disclosure In a synthesis of urea using ammonia in a highly excessive molar ratio, unreacted materials are decomposed and separated by subjecting the urea synthesis effluent to a stripping step using carbon dioxide at a pressure equal to the urea synthesis pressure.  The thus-separated gaseous mixture of ammonia and carbon dioxide is condensed through an indirect heat exchange with an effluent stream discharged from the stripping step and lowered to a pre-determined pressure level.  Resulting condensation heat is used for the decomposition and separation of unreacted materials still remaining in said effluent stream.  By choosing suitable operation conditions for each step of the present invention, it is possible to reduce the amount of high pressure steam to be required and to minimize the amount of low pressure steam to be recovered.

The flow direction of the medium to be filtered through the filter structure and the direction of the magnetic field are arranged perpendicular to the wire screens.  To prevent turbulence at high flow velocities, which causes inhomogeneous separation, at least on the inlet side of the filter structure, magnetic field carrying elements of ferromagnetic material are connected to the corresponding yoke part and extend up to the filter structure, the elements distributed at least approximately uniformly over the entrance surface of the filter structure, and the total cross-sectional area of the elements occupying approximately between 1/4 and 1/2 of the entrance area.
