  • Patent number: 5634831
    Abstract: A water jet propulsion unit intended for use in jet boats. The unit has an intake section, a pump section and a nozzle section. In the pump section there are two counter-rotating impellers on concentric counter-rotating shafts calibrated so that any radial flow created in the upstream impeller is converted into axial flow by the downstream impeller. In one embodiment the nozzle section has a throttled outlet to allow for a high mass/low pressure operation while maintaining pump priming. There are no support structures or stators downstream of the intake section in the preferred embodiment.

  • Patent number: 5480189
    Abstract: Accordingly, the present invention is an automotive vehicle frame including a forward portion, a rear portion and a central portion disposed between the forward portion and the rear portion. Either one of the forward and rear portions include at least one rail extending longitudinally. The rail includes a first structural member having an open cross-section and marginal flanges. The rail also includes a second structural member closing the open cross-section of the first structural members. The second structural member includes edge portions disposed over and in abutting relationship with the marginal flanges.

  • Patent number: 4247422
    Abstract: A method of making and using a metallic supported catalytic system for automotive emission control is disclosed. A plain carbon steel foil is formed into a matrix having a plurality of aligned micropassages; forming is preferably carried out by corrugating one strip of foil and winding said corrugated strip along with one or more noncorrugated foil strips to create a honeycomb matrix. The formed matrix is then immersed in a hot lead bath containing alloying ingredients which displace iron atoms in said foil to provide diffusion alloying substantially throughout the entire thickness of said foil. The contact points between said foil strips are diffusion bonded to lock the entire matrix. The alloyed matrix is then heated to form an oxide film from at least one of the alloying ingredients. The bonded matrix is then coated with a refractory wash and with a catalytic ingredient.

  • Patent number: 4222796
    Abstract: A method of making, and the resulting product, of a dual-phase steel having increased tensile strength and a favorable ductility level is disclosed. The method comprises adding 0.1-0.2 Mo to 0.3-0.5 Cr and/or 0.7-0.2 V, to constitute a combined additive to a manganese-carbon-base steel. Upon heating to the insensitive portion of the intercritical annealing range (740.degree.-830.degree. C.) for 8 minutes and cooling at a rate less than 100.degree. C./sec., a dual-phase steel is produced having about 30% volume fraction martensite and a tensile strength level of about 150 ksi with a 12% elongation value.

  • Patent number: 4196025
    Abstract: A method of making, and the resulting product, of a dual-phase steel having increased tensile strength and a favorable ductility level is disclosed. The method comprises adding 0.1-0.02 Mo to 0.3-0.5 Cr and/or 0-0.15 V, to constitute a combined additive to a manganese-carbon-base steel. Upon heating to the insensitive portion of the intercritical annealing range (740.degree.-830.degree. C.) for 8 minutes and cooling at a rate less than 100.degree. C./sec., a dual-phase steel is produced having about 30% volume fraction martensite and a tensile strength level of about 150 ksi with a 12% elongation value.
