摘要： A wayside lubricator for railroad cars has a number of sensors mounted adjacent the track which detect the approach and passage rail cars. A lubricant supply and a pressurizing system are mounted adjacent the track and in fluid communication with a control valve and spray nozzle. The spray nozzle is aimed to shoot lubricant into a target zone when the control valve is opened. The spray nozzle is turned on for a defined duration of time so that the quantity of the lubricant is kept under control. Application of the lubricant to the wheels of the locomotive is avoided by detecting locomotive wheels and leaving the valve closed until they pass. This invention reduces the friction between the wheel tread and rail on curves for the trailing cars and thus reduces the friction and the force that is experienced by the wheel flanges on curves.

摘要： A lubrication system for a railroad locomotive applies a lubricant with great accuracy in computer-controlled, precise quantities behind the last axle of the last locomotive such that the lubricant is consumed by the time the entire train has passed under all track, speed, temperature and train size conditions. Hydraulic pulse-width modulation (PWM or % PWM) controls the quantity of lubricant delivered. Time is divided into a series of windows each consisting of a few seconds. Lubricant delivered from a pressurized tank through long hoses to a solenoid controlled valve is then metered by the duration within this time window for which the computer computes and opens the valve. Compensation is provided for train tonnage and lubricant temperature as well as track curvature and train speed.

摘要： In railroad operations, a method and apparatus for optimizing on-board rail lubrication for both curved and tangent track. The apparatus is mounted on the car body of the last locomotive of a locomotive consist behind the last axle. A lubricating device applies two different lubricants, one on the crown of the rail and the other on the gage side. The amount and type of the crown lubricant are chosen such that the crown lubricant is totally consumed by the passage of the train wheels. The amount of application of the two lubricants is controlled by a microprocessor. A new sensor has been devised which measures degree of rail curve and estimates the angle of attack of the wheel on the rail by converting lateral displacement into either of the two quantities. This value is provided to the microprocessor. Other sensors measuring speed, temperature, humidity, etc. provide input signals to the microprocessor. This invention not only reduces the friction coefficient between the wheel flanges and the rail but also reduces the forces between the wheel flanges and the rail. Both rail and wheel wear are reduced while simultaneously also reducing the fuel consumed in the train.

摘要： A system and method for generating an electronic publication (e.g., an e-book) sample having an end point designated in accordance with a set of heuristics. A start reading location is identified within the content of an electronic publication. A sample block is identified which includes a percentage of the content following the start reading location. A set of heuristics (e.g., rules) configured to identify an end point for the e-book sample is applied to a selected portion of the content within the sample block. The end point of the sample block is designated according to the set of heuristics and the electronic publication sample having the designated end point is stored.

摘要： A friction management system for a traveling crane applies a liquid or solid friction modifier (FM) in precisely controlled quantities to the crane wheels or rail to improve performance and safety during movement of the crane. The friction modifier is applied by a nozzle mounted on a crane truck, which nozzle is opened and closed by a valve. The duration of the valve opening per second, which controls the friction modifier application rate, is approximately proportional to the average current draw, which is detected by current sensors connected to the truck motors.
