摘要： A keyboard assembly for a computer with movable keyboard pallets. The pallets are movable relative to each other between a compact stowing position and an extended operational position. A movement mechanism moves at least one of the pallets in a lateral direction relative to the other pallet and then towards the other pallet in a direction orthogonal to the lateral direction. The movement mechanism can be connected to the cover of the computer to automatically control movement of the pallets based upon position of the cover relative to a base of the computer. Thus, the pallets can be automatically moved from the compact stowing position, when the cover is closed, to the extended operational position when the cover is opened. Upon moving the cover from the open position to the closed position, the pallets are automatically moved from the extended operational position to the compact stowing position. The movement mechanism includes a drive arm with a spring section. The spring section allows the pallets to be biased toward each other in their stowing position. The spring section is preloaded such that it does not function as a spring until a predetermined force is applied to the spring section.

摘要： A self pressurizing journal bearing assembly includes a tubular housing having a bore defining a plain cylindrical journal bearing, and a cylindrical rotary shaft disposed coaxially therein. The shaft includes a plain cylindrical journal spaced radially inwardly of the bearing to define a journal bearing gap. A screw pump is defined in part by a portion of the shaft, and is disposed inside the housing bore in flow communication with the journal bearing for continually circulating a lubricant thereto under pressure upon rotation of the shaft for accommodating lubricant end leakage from the journal bearing.

摘要： This invention is a non-contact axial flow turbo blood pump for propelling blood, which is composed of a pump housing (24) that defines a pump axis, with inlet, outlet openings at opposite axial ends of the pump housing, a rotor unit (17) that defines a rotor axis, and opposing rotor axial ends. The pump magnetically suspends the rotor within the pump housing at the rotor axial ends so as to avoid causing physical contact between the housing to define fluid gaps between the rotor axial ends, and the magnetic suspension elements (13)(13′).

摘要： A low cost multi cylinder radial aircraft engine is composed of an even number of individually functional, single cylinder slider crank model engines. They are mounted to a plate to form equally spaced radially oriented cylinders. In the preferred embodiment, use of standard, low cost, & mass produced two cycles engines are used. This in conjunction with a novel exhaust muffler and throttle mechanism results in a low cost radial engine. The individual engine shafts surround and are parallel to a central output shaft. Pinion gears on each shaft transfer power to a larger sun gear on the output shaft. This gearing synchronizes opposed pistons to reach top dead center at the same time resulting in vibration free piston motion and perfect balance of the entire engine. Said gearing also provides speed reduction for use of large diameter scale propellers. A rear mounted throttle mechanism controls individual carburetor throttles. Each cylinder radially exhausts into a donut shaped exhaust manifold that also serves as a muffler at the front of the engine. It very effectively lowers cylinder exhaust noise by using opposed flow impingement. The muffler also utilizes turbulent gas cooling to greatly reduce exhaust gas temperature and energy. This results in very low noise like its 4 cycle competitor.

摘要： A linear stroke reciprocating electric machine provides both high efficiency and linearity. A cylindrical air gap is defined between outer and inner gap defining surfaces, at least one of which has a length equal to the length of an electric coil plus the length of the stroke. A flux focusing ring, having a length in the direction of movement equal to the length of the coil in the same direction, concentrates substantially all the field flux and all of the electric coil turns to interact over the entire stroke.
