Patent BR-8301565-A (BR)
Inventor: SHARP RICHARD FELIX
IPC: F02M61/20
Filed: 1983-03-25
Abstract: A control device and method for opening and closing the nozzle of a fuel injector. The control device includes first and second cavities which are formed in the body of the fuel injector, with the second cavity being located close to the nozzle. First and second variable pressure supply chambers are connected to the nozzle and to the two cavities by several fluid passages. A spool valve and a needle valve are positioned in the first and second cavities, respectively, with the spool valve abutting a stem which projects into and terminating in the second cavity. Also situated in the second cavity between the stem and the needle valve is a spring which forms a link therebetween. The spool valve is pressure-actuated by a difference of pressure in the first and second pressure chambers to move between an open and a closed position. In the open position, fluid flow from one of the pressure chambers is permitted through the spool valve and to the second cavity. As the fluid pressure in the second cavity increases to a value greater than the compressive force of the spring, the needle valve will open and allow fluid flow through the nozzle of the fuel injector. As the spool valve moves to its closed position, it compresses the spring further and then urges the needle valve to close. The needle valve closes prior to a drop in fluid pressure in the second cavity.

Abstract: A process for the production of valve seat rings by powder metallurgy wherein molybdenum disulfide in the range of about 0.5% to 1.5% by weight is added to a powder mixture containing 0.8% to 1.5% by weight graphite, 1.0% to 4% by weight lead, 0.5% to 5% by weight nickel, 1.2% to 1.8% by weight molybdenum, 9.6% to 14.4% by weight cobalt, and the remainder iron. The resulting powder mixture is pressed into valve seat rings at a pressing force between 40 and 60 and preferably 50 KN/cm2. The rings are then sintered in a neutral atmosphere at a temperature of 1100 DEG  C. to 1200 DEG  C., finally compressed at a pressing force above 120 KN/cm2 and heat-treated if required. The resulting valve seat rings have greatly improved wear properties when used in internal combustion engines using lead-free gasoline.

IPC: C22C1/10
Filed: 1989-11-10
Abstract: A metal matrix composite is formed by contacting a molten matrix alloy (18) with a permeable mass of filler material or preform (16) in the presence of an infiltrating atmosphere. Under these conditions, the molten matrix alloy (18) will spontaneously infiltrate the permeable mass of filler material of preform (16) under normal atmospheric pressures. Once a desired amount of spontaneous infiltration has been achieved, or during the spontaneous infiltration step,the matrix metal which has infiltrated the permeable mass of filler material or preform (16) is directionally solidified. This technique allows the production of spontaneously infiltrated metal matrix composites having improved microstructures and properties.

Abstract: <B>PROCESSO DE PRECIPITAçãO DE ALTO REDIMENTO<D>, para precipitar triidrato de alumina a partir de uma solução cáustica saturada compreendendo o fornecimento da solução cáustica saturada (10) a um estágio de precipitação de uma fábrica de Bayer. O estágio de precipitação inclui um estágio de aglomeração (A1, A2) e um estágio de crescimento (G1, G2... G último). A precipitação do triidrato de alumína ocorre no estágio para formar uma massa fluida da triidrato precipitado na solução cáustica. Durante o processo de precipitação, a massa fluida é diluída através da adição de um fluido aquoso (115). Este dilui a concentração cáustica da solução na massa, o que aumenta a força de iniciação da precipitação, aumentando desta forma os rendimentos do processo de precipitação. O fluido de diluição pode ser adicionado à massa fluida como um fluido único ou como uma pluralidade de fluidos.
