Patent number: 4536361Abstract: Relatively long plastic microfilaments are used to make reinforcing, filler materials and fabrics. A blowing gas is applied at a positive pressure to the inert surface of a liquid plastic film formed across a coaxial blowing nozzle to blow the film and form an elongated hollow tube having a thinned wall or weakened portion. An entraining fluid is directed at an angle over and around the blowing nozzle and as it passes over and around the blowing nozzle, it dynamically induces a pulsating or fluctuating pressure field at the opposite side of the blowing nozzle in the wake thereof and produces a laminar flow of entraining fluid in the vicinity of the forming elongated tube.Type: GrantFiled: November 16, 1982Date of Patent: August 20, 1985Inventor: Leonard B. Torobin

Patent number: 4416638Abstract: To avoid danger of fuel leakage into bilges of a vessel's hull, the fuel feed pipe from the fuel supply to the vessel's engine carburetor is enclosed within a cylindrical casing sealed at one end to a fitting on the carburetor. At its other end the casing is sealed to an aperture in the hull, the feed pipe extending externally of the hull between the aperture and a container enclosing the fuel supply. Alternatively the casing is sealed at its other end directly to the container. The carburetor may have an annular fuel feed chamber with adjustable fuel orifices connected to the feed pipe through a scroll valve linked to the carburetor throttle valve.Type: GrantFiled: August 26, 1982Date of Patent: November 22, 1983Inventor: Frank Ellis

Patent number: 4415512Abstract: Hollow metal microspheres are made by forming a liquid film of molten film forming metal composition across a coaxial blowing nozzle and applying a blowing gas at a positive pressure on the inner surface of the metal film to blow the film and form an elongated cylinder shaped liquid film of molten metal. An inert entraining fluid is directed over and around the blowing nozzle at an angle to the axis of the blowing nozzle so that the entraining fluid dynamically induces a pulsating or fluctuating pressure field at the opposite side of the blowing nozzle in the wake of the coaxial blowing nozzle. The continued movement of the entraining fluid produces asymmetric fluid drag forces on the cylinder and closes and detaches the elongated cylinder from the coaxial blowing nozzle. Surface tension forces acting on the detached cylinder form the latter into a spherical shape which is rapidly cooled and solidified by cooling means to form a hard, smooth hollow metal microsphere.Type: GrantFiled: March 18, 1981Date of Patent: November 15, 1983Inventor: Leonard B.
