Title: Bistable pitch propeller system with bidirectional propeller rotation
Inventor: Reichert Todd
IPC: B64C11/42
Filed: 2017-03-13
Abstract: Disclosed is a method for controlling the pitch angle of a propeller when the propeller is rotated in opposing directions that is mechanically simpler and lighter than existing systems. A propeller includes a blade free to rotate. A first stop is positioned to mechanically engage one or both of a first portion of the blade and a first structure coupled to the blade when the blade is in a first position at a first end of the rotational range of motion. A second stop is positioned to mechanically engage one or both of a second portion of the blade and a second structure coupled to the blade when the blade is in a second position at a second end of the defined rotational range. The blade rotates to the first position against the first stop when the propeller is rotated in a first direction and to the second position against the second stop when the propeller is rotated in a second direction.

Abstract: FIELD: medical engineering. SUBSTANCE: device has casing, pump for feeding filling material, canal filler unit and metering unit. The casing has threaded parts on both sides, one of which has coupling nut to fasten canal filler unit having hollow needle with flange. The opposite threaded part of the device casing with main piston stroke stopper forms metering device having also digital graded scale showing the piston stroke stopper revolutions number and stopper position control scale within the range of one revolution. The canal filler unit has discharge chambers for performing main and preparative pumping-in filling material. Main discharge chamber has main piston engageable with the working cylindric portion of a cavity of the hollow needle being 1.2 mm in diameter. This part of the cavity transforms into conic nozzles on both ends. Needle working end shape is truncated cone turned with its greater base towards the needle flange. The chamber for precompressing is made in form of auxiliary piston engageable with cavity of the chamber for precompressing filling mass so that the cavity of the chamber for precompressing filling mass communicates with the blind opening in the bottom of the chamber. Beside that the chamber for precompressing filling mass is autonomous unit of the device which through hole in the bottom coincides in form and size with the conic needle end. The depth of the through hole in the bottom does not exceed the conic needle end height by a value not less than one diameter of the lower base of the needle end cone. The hollow needle with the chamber for precompressing filling mass and auxiliary piston are manufactured, to satisfy the requirement of single use, from cast polymer material possessing both anti-adhesion properties with respect to filling material and a property to retain deformed state, when bending moment is applied to, for instance, the needle working end.

Title: Catalytic reactor and process
Inventor: BOWE MICHAEL JOSEPH
IPC: B01J19/24
Filed: 2002-12-04
Abstract: Methane is reacted with steam, to generate carbon monoxide and hydrogen in a first catalytic reactor; the resulting gas mixture can then be used to perform Fisher-Tropsch synthesis in a second catalytic reactor. In performing the steam/methane reforming, the gas mixture is passed through a narrow flow channel containing a catalyst structure on a metal substrate, and adjacent to a source of heat, in a time less than 0.5 s, so that only those reactions that have comparatively rapid kinetics will occur. Both the average temperature and the exit temperature of the channel are in the range 750 DEG C to 900 DEG C. The ratio of steam to methane should preferably be 1.4 to 1.6, for example about 1.5. Almost all the methane will undergo the reforming reaction, almost entirely forming carbon monoxide. After performing Fischer-Tropsch synthesis, the remaining hydrogen is preferably used to provide heat for the reforming reaction.
