Title: Connected pipe channel for regulation of level in condenser and feeding tank in transitive regime of work power block 300 mw
Inventor: TEOFILOVIC RADOVAN
Filed: 2002-01-29
Abstract: Patent application relates to connecting pipeline for level regulation in condenser and in feeding tank at transition operation regime of 300 MW power block. Blocks of this kind are installed in thermo electric power plant "Nikola Tesla"-A in Obrenovac. In transition operation mode part of circular flow of feeding water (feed tank (14), boiler (19) and starting containers (22)) are filled in without control by steam supply over valves (15) and condensate passage over governing valve (9) and shaft gasket of feeding pumps over pipeline (16), while turbine condenser (5) is being emptied. This brings to manifestation of extreme levels in feeding tank (14) and condenser (5) that is hardly possible to overcome with operation of level regulation in automatic regime. Manual intervention includes ejection of a certain quantity of chemically prepared water from the system. Building in the connecting pipeline (31) along appropriate reinforcement - valves (29) and (30) - enables circulation between feeding tank (14) and turbine condenser (5), namely, bringing to range and providing operation of level regulation in automatic regime at all operational boiler loading.

Abstract: ABSTRACT OF THE DISCLOSURE       A fire retardant polymeric composition comprising a polymer or copolymer of an unsaturated hydrocarbon and a Diels Alder adduct of a halogenated cyclopentadiene and bicyclononadiene.  The fire retardance of the materials can be further enhanced by the incorp-oration therein of a metallic compound, particularly a compound of antimony, arsenic or bismuth.  A preferred metallic compound is antimony oxide.  The fire retardance is demonstrated by the fire retardant efficiency and lower after glow in the compositions; the compositions also have improved heat deflection properties and tensile and flexural properties as compared with similar polymer compositions containing known fire retardant Diels-Alder adducts.

Abstract: ABSTRACT OF THE INVENTION Stencil cutting apparatus for electrically burning information from an original document into a stencil material having non-linear burning char-acteristics by the application of electrical pulses to a stylus contacting the stencil material positioned on a rotatable cylinder, includes a photo-multiplier for scanning the original document and providing an output signal the amplitude of which is proportional to the light reflected by the informa-tion thereon, a circuit including a square wave oscillator and wave shaping network which alters the square wave in relation to the burning character-istics of the stencil material to produce a resultant train of pulses and a comparator circuit which adds the photomultiplier signal and train of pulses. The comparator provides output pulses having a width determined by the addi-tion of the last-mentioned signal and pulses which are fed to the stylus for burning the stencil.  The cylinder upon which the stencil material is mounted includes a magnet which revolves as the cylinder rotates.  The movement of the magnet past a sensing coil produces a signal to discontinue the burning as the stylus passes over the stencil clamp of the cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE           A "G" seat for providing kinesthetic (sensation of motion) cues to a pilot of a simulated aircraft.  The seat is designed specifically to stimulate elements of the haptic sensory system and is capable of independently producing desired skeletal attitude shifts, area of flesh contact changes and flesh pressure gradient variations and coordinating same to simulate acceleration effects.  The seat contains two mosaics of air cells forming a seat cushion and a back cushion, respectively.  The air cells comprise tension spring loaded bellows having rigid top plates.  The top plates of the cells in each mosaic form a body supporting surface of the corres-ponding cushion.  The cells may be individually driven under computer control to vary the elevation, attitude and shape of these body supporting surfaces.  In addition, clam-shell shaped air cells are positioned on either side of the seat cushion to provide thigh pressure and area of contact variations and a lap belt is driven to provide ventral area pressure variation.         The invention herein described was made in the course of or under a contract or subcontract thereunder, with the Department of the Air Force.

Abstract: ABSTRACT OF THE DISCLOSURE    A rotary valve system for an internal combustion engine is disclosed.  Through the provision of an axially movable valve rotor, the system is capable of variable valve opening duration and timing.  Ports in the rotor or in the rotor housing, or both, have edges inclined with respect to the axis of the rotor, so that relative axial movement of the rotor and housing ports effects a change in the timing of valve opening and closing.  Valve opening duration is also varied.  An actu-ator system which controls the axial translation of the rotor during operation of the engine considers factors affecting engine performance such as engine speed, road speed and engine loading in determining the optimum valve timing and duration setting.

Abstract: ABSTRACT OF THE DISCLOSURE An electron tube of the type, such as a traveling-wave tube, which includes a cylindrical ceramic envelope part jointed to two spaced metallic electrodes between which a high D.C. voltage is applied is disclosed.  The ceramic part has its inner diameter progressively increased so that its inner circumferential surface is flared from the end at which the negative potential electrode is jointed towards the end at which the positive po-tential electrode is jointed.  Because electrons emitted from the cathode of the tube are less likely to impinge on this sloping surface, arc gener-ation is reduced or prevented.  Additionally, a metallic shield connected concentrical b to the negative electrode is provided, the shield being so spaced with respect to the positive electrode that it concentrates the field between the two electrodes at the shield.  This weakens the field at the periphery of the negative electrode and causes reduced emission of electrons at that location.
