Abstract: A method for the configuration of network elements includes initially configuring a network element via a controller. The controller characterizes (learns) the configuration steps as a series of menu driven screen commands associated with the network element and processes subsequent substantially similar configuration requests for the network element and other network elements of the network using the characterized series of menu driven screen commands to execute the subsequent configuration requests. As such, the configuration and set-up of new network element(s) or the subsequent modifications to the configuration of existing network element(s), are vastly simplified processes. The present invention advantageously reduces the number of needed manually input parameters, thus making the configuration of network elements more reliable.

The propeller shaft includes a polygon shaped propeller driving element that is countersunk into a rear portion of the propeller. A shaft stabilizing arrangement is positioned adjacent an end of the shaft where the shaft connects with the motor.

Abstract: A method and apparatus to increase the performance of a floating point multiplier accumulator (FMAC). The method comprises receiving three floating point numbers and computing a product of the first floating point number and the second floating point number and adding a third floating point number to produce a sum value and a carry value. A propagate value, a kill value and a generate value are then computed based on the sum value and the carry value. Simultaneously the sum value is added to the carry value to create a first result, the sum value is added to the carry value and incremented by one to create a second result, the sum value is added to the carry value and incremented by two to create a third result, and a decimal point position is determined. One of the first result, the second result and the third result is then selected responsive to a rounding mode and the decimal point position. The selected result is normalized based on the decimal point position.

Abstract: A helical gear is disclosed that is formed by an injection molding process in which the mold cavity is formed of mirror finished hardened stainless steel. The helical gear is disclosed in a gear box that entirely encase the gears, and may be integral with the housing of the toy. Furthermore, an “L” axle for gears is disclosed that provides a straight shaft portion that extends through the axle bearing aligned with the centerline of the gear and a bent portion that is seated in a slot recess in the wall of the gear box.

Abstract: A process for catalytically directly producing hydrogen peroxide (H.sub.2O.sub.2) product from hydrogen and oxygen-containing feeds by contacting them with a supported noble metal phase-controlled catalyst and a suitable organic liquid solvent having a Solvent Selection Parameter (SSP) between 0.14.times.10.sup.−4 and 5.0.times.10.sup.−4 at reaction condition of 0-100.degree. C. temperature and 100-3,000 psig pressure. Unconverted feed gas and organic liquid solvent solution are usually recovered and recycled back to the reactor along with any recovered catalyst. If desired, the hydrogen peroxide product can be fed together with an organic chemical feedstock such as propylene and with the organic liquid solvent solution into a second catalytic reaction step which oxidizes the feedstock to produce a desired crude oxidized organic product such as propylene oxide, which may be purified by distillation steps and recovered from the solvent solution.

Abstract: The present invention relates to a new low-power, high performance multiplier circuit design, and more specifically to a partitioned multiplier implemented using a modified, symmetrical Wallace tree structure that enables the power to parts of the multiplier to be selectively turned on and off. A multiplier implemented using complementary pass-transistor logic (CPL) 3:2 carry save adders (CSAs) includes a left array with a first multiple of CPL CSAs, a right array with a second multiple of CPL CSAs, and a merge block coupled to the left array and the right array, such that the left and right arrays are not coupled to each other. The left and right arrays are configured to independently receive power, such that, each array can be turned on and off without affecting the other array. The merge block includes a third multiple of CPL CSAs and the merge block can be configured to output a result value of a multiplication operation.
