Abstract: This invention relates to high reduction planetary transmissions that do not use internal ring gears and particularly planet gears that are the support for the planet carrier and in some cases the planet carrier may be used as a support bearing for the input shaft relative to the stationary and output gears with which they mesh. The floating is accomplished by providing means to let the carrier move radially in response to unbalanced forces from the planet gears. The floating of the planet gears improves the alignment between the intermeshing gears and the balancing of the load between the planet gears. A speed reducing device placed between the input shaft of the transmission and the drive means is used to decrease the speed of the input shaft to decrease the centrifugal force on the planetary pinions as they rotate around the sun and output gears.

Abstract: This invention relates to high reduction planetary transmissions that do not use ring gears and particularly planet gears that are the support for the planet carrier. The planet carrier is entirely supported by the planet gears meshing with their respective sun and output gears. The planet gears can move in a radial direction to improve tooth alignment between the meshing gears and equalize the distribution of the torque load between the planet gears. In some cases the planet carrier may act as one of the support bearings for the input shaft.

Abstract: A brush holder assembly for an electric machine such as a motor that utilizes a constant force spring positioned within a U-shaped retainer to apply a constant force on a brush positioned against the spring within the retainer. The brush, spring and retainer are positioned within a container mounted on the housing of the electric machine. A removable cap is mounted in the radially outer end of the container to maintain the brush and spring in proper position during operation and allow easy removal and replacement of the brush when needed.

Abstract: This invention relates to a mechanism for adjusting the position of the roller bearings that support large rotating apparatus such as a rotary kiln. The mechanism utilizes a box like base mounted on the kiln foundation. The base has a pair of compartments. In the rear compartment a fluid pressure device actuates a piston to drive a threaded bolt against the base of the roller bearing to adjust its position. A stop nut on the threaded bolt is moved to engage a wall of the base to prevent movement of the bolt away from the bearing and thereby maintain the bearing in its adjusted position.

Abstract: A thermal treatment system for converting contaminants in soil to non-hazardous compounds. The system includes a combustion chamber in which the soils to be treated are heated to a temperature above the volatilization temperature of the contaminants in the soil. Reagents are injected into the gas stream above the soil which contains the volatized contaminants to interact with the inorganic contaminants to form solid particles that can be collected on a filter for safe disposal. The volatized organic contaminants are burned to form non-toxic combustion gases.

Abstract: A system for the controlled safe shutdown of a hazardous waste incinerator upon loss of power. The system includes a primary combustion chamber and a secondary combustion chamber, a gas treatment system, and two standby power sources. One standby power source is available immediately for elements that cannot be shut down even for a second. The other standby power source is a heavy duty generator that takes a short time to get up to speed but is used to power elements that can be allowed to coast for a short time without causing damage to the equipment or the environment. The system includes an uninterruptable power source connected to continue supplying heat and air to the secondary combustion chamber and prevent opening an emergency vent stack cap and thereby prevent the unwanted discharge of gas from the system.

Abstract: A method of pyroprocessing mineral ores. The method includes forming the mineral ore fines into small balls or pellets, drying and preheating the pellets and then subjecting the pellets to further heat with an oxidizing gas to substantially oxidize and indurate the pellets prior to discharging the pellets into a cooler. The essential equipment used in the process are machines such as a balling pan or drum for agglomerating the ore, a grate traveling through a furnace and a rotary kiln for transporting the pellets from the grate to a cooler. Also, means are provided to supply hot oxidizing gas to both the furnace and the kiln to heat the pellets. In addition, means are provided to supply an oxidizing gas beneath the tumbling bed of pellets in the kiln.

Abstract: A method of repairing large rotating parts joined together by bolts extending through flanges extending radially from the parts being joined. The method comprises the steps of removing the bolts, separating the parts, counterboring the areas around the bolt holes, inserting an annular washer in the area counterbored and rebolting the parts together.

Abstract: A seal for use in sealing an annular opening between a stationary member and a rotating cylinder telescopically arranged with the stationary member, the seal comprising a series of partially overlapping members circumscribing the cylinder adjacent the stationary member and closing the annular opening. The seal comprises a series of self-biasing leaf members attached to the stationary member and being biased into sealing engagement with the rotating member and a series of blanket members positioned adjacent the seal members to prevent leakage from the gaps between adjacent leaf members to substantially seal the annular opening between the rotating and stationary members.

Abstract: A device for monitoring the electrical arc voltage and arc current being supplied by a welding apparatus. The device includes means, as for instance an electronic circuit, for integrating each electrical quantity being utilized over a selectively variable time period to provide a running weighted average indication of said quantity. The device also includes a means, as for instance an electronic circuit, to provide a memory so that a welder can measure his own parameters.
