    Abstract: Novel methods of Fischer-Tropsch synthesis are described. It has been discovered that conducting the Fischer-Tropsch synthesis over a catalyst with a catalytically active surface layer of 35 microns or less results in a liquid hydrocarbon product with a high ratio of C5-C20:C20+. Descriptions of novel Fischer-Tropsch catalysts and reactors are also provided. Novel hydrocarbon compositions with a high ratio of C5-C20:C20+ are also described.

    Abstract: An electric actuator for an automatic transmission includes an adapter to transmit rotary motion between the adapter and the transmission. An electric motor has an output shaft operably connected the adapter by a gear set which includes a ring gear. A release mechanism includes a solenoid which selectively moves a lock member. In a first position, the lock member engages the ring gear to lock the ring gear so that the adapter is rotated by rotary motion of the output shaft and the adapter rotates to a predetermined zone about a desired gear position. In a second position, the lock member is out of engagement with the ring gear to permit rotation of the ring gear so that the adapter is rotated by internal forces of the transmission and the adapter automatically self-aligns to the exact desired gear position when the adapter is within the predetermined zone.

    Abstract: A system, method and apparatus for comparing two floating point numbers is includes choosing a first floating point number and a second floating point number to be compared. The first number is sign extended one bit to create a first sign extended number. The second number is sign extended one bit to create a second sign extended number. The second sign extended number is subtracted from the first sign extended number to determine a subtraction result. The sign bits for said first number and said second number are examined to determine if they are both ones. If the sign bits for the first number and the second number are both ones, the sign bit of the subtraction result is inverted to create a final result. If the sign bit of the final result is a zero, asserting that the first number is greater than or equal to the second number. Alternatively, if the sign bit of the final result is a one, asserting that the first number is less than the second number.
