摘要： Gears, particularly spur gears, are produced by powder metal techniques with minimal lead line error and eccentricity, which gears are preformed from powder metal, sintered, hardened and thereafter have their involute surfaces regenerated by a hard hob with a negative rake on the hob teeth to provide gears having aligned involute surfaces between adjacent gear teeth and, between each gear tooth and the gear center line.

摘要： An arc furnace fume collection system has a plurality of duct lines leading to a common duct that leads to a baghouse for filtering dust. The supplemental duct lines have high pressure fans, blowers, or compressors and join one of the other duct lines through a nozzle. The nozzle connection acts as a venturi to supplement the pulling power of a common exhaust fan downstream of the baghouse filter.

摘要： The present invention provides a system and method for collecting fumes from an arc furnace of the type typically used in metal foundries. The system provides an electrode hood with extended sides for improved collection of fumes from the vicinity of the electrodes. It also provides a movable spout hood for collection of fumes when metal is tapped. A combination of a tilting manifold and stationary duct are used to maintain a path for collecting fumes throughout the entire range of motion of the furnace. The stationary duct has a group of dampers that open and close as the furnace tilts. Variable position dampers may be provided at the electrode hood and furnace door. In the bag house, there is a dust containment assembly to limit the movement of the collected dust. A variable speed fan may be used with the system. One method of the invention involves determining the pressure differential upstream and downstream of the filter bag, determining the fan speed, and closing a damper downstream of the filter to clean the filter bag when the determined values for the pressure differential and fan speed match previously set values. The entire system may be controlled by a programmable logic element to maximize efficiency. Another method involves the steps of adjusting the electrode hood damper, spout hood damper and door hood damper in response to furnace conditions.

摘要： Cast iron pipe and other elongated hollow articles are lined with a cementitious mortar for certain applications, such as the transmission of potable water or sewage. To improve the resistance to attack from acids and to provide a crack and holiday free cement lining, a calcium alumina cement is used to line the article. A plasticizer such as fireclay is added to the calcium alumina cement prior to its application. The cement lined article is then coated with an asphaltic based coating and then cured in a high humidity environment.

摘要： A method and system for cutting hub bores in metal railroad wheels is disclosed. The system includes a lead and second torch for cutting the hub bores. In the method, the lead torch is moved to an initial position above the wheel. The lead torch is energized and moved to cut through a part of the wheel. The second torch is moved to an initial position above the wheel. The second torch is then energized and moved to cut through a part of the wheel. The entire hub bore is cut in the wheel. Additional torches may also be provided. A gantry system for supporting the lead and second torches is disclosed. The gantry system includes lead and second linear movement means arranged parallel to each other and a third linear movement means perpendicular to the lead and second linear movement means. The gantry system also includes a lead torch carriage means for supporting the lead torch and a second torch carriage means for supporting the second torch. The lead torch carriage means is connected to be movable by the lead linear movement means and the second torch carriage means is connected to be movable by the second third linear movement means. The lead and second linear movement means are supported by the third linear movement means and connected for independent movement along the third linear movement means. The hub-cutting system may include a position sensing means, a temperature sensing means, and a control means that allows the movement and speed of the lead torch and second torch to be adjusted based upon the sensed position and temperature of the wheel.

摘要： When slack-free railcar connector assemblies are placed under very high tensile loading, the connector assembly components will stretch and allow a typical "rigid" gravity wedge to descend into a fully seated position between the components and lock-in the tensile loads. The locked-in loads become additive in nature when successively encountered compressive loads are experienced by the connector assembly, thereby increasing the lateral drawbar angling forces, as well as accelerating coupling component wear. The wedge component of the present invention includes a means for vertically supporting and retaining the wedge in a holding position slightly above the normally fully seated position during the tensile loading, thereby eliminating the build up of tensile forces in the connector assembly.
摘要翻译： 当无松动的有轨车连接器组件放置在非常高的拉伸载荷下时，连接器组件部件将伸展并允许典型的“刚性”重力楔下降到部件之间的完全就位位置并锁定拉伸载荷。 当连接器组件经历连续遇到的压缩载荷时，锁定的载荷本质上变成添加剂，从而增加横向牵引杆的倾斜力，以及加速耦合部件的磨损。 本发明的楔形部件包括用于在拉伸加载期间将楔形件垂直地支撑并保持在略微高于正常完全就座位置的保持位置中的装置，从而消除了连接器组件中的拉伸力的累积。

摘要： A structural device is attached to each sideframe pedestal jaw of a railcar truck wherein the bearing adapter is joined to the sideframe and is prevented from rotating within the pedestal jaw opening. The bearing adapter inboard and outboard faces maintain a parallel relationship with the sideframe inboard and outboard faces during operations, including curving, thereby causing the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck wheel misalignment, which directly effects truck hunting and curving.

摘要： A railway vehicle truck bolster friction shoe pocket includes a sloped rear wall and longitudinally spaced sidewalls depending from the rear wall to form a friction shoe pocket having open top and bottom ends for receiving a variable rate type of friction shoe. During rotation and translation of the bolster with respect to the truck sideframe, the outboard friction shoe pocket sidewall is repeatedly impacted by the outer and upper corner of the friction shoe. The impacting causes protuberances to form in the outboard sidewall, but only on the upper portion of the wall. The same sidewall is provided with a relieved section across the entire sidewall upper portion in order to eliminate the impact contact area between the upper portion of the friction shoe and the upper portion of the outboard sidewall. Eliminating the contact area eliminates the formation of protuberances and extends the life of the bolster.
