Filed:

May 30, 2000

Appl. No.:

09/583308

Inventors:

Sudhir Kumar - Darien IL

Assignee:

Tranergy Corporation - Bensenville IL

International Classification:

B61K 300

US Classification:

184 32

Abstract:

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.

Assignee:

Tranergy Corporation - Bensenville IL

International Classification:

G01D 21/00

US Classification:

738665

Abstract:

A rail-mounted, wheel-sensing system is shown having a wheel sensor and a rail mounting platform. The system includes a rugged steel rail clamp including two blocks mounted on the base of the rail by a pair of bolt extending under the rail. One block is connected to a vertically adjustable mounting bracket for carrying a sensor or other device. The mounting bracket includes a platform for the sensor. Two shields on the platform protecting a sensor mounted between them. An adapter plate may be added between the mounting bracket and the clamp for installation on lighter or heavier rails.

International Classification:

B61K 3/00

US Classification:

184 32, 184 31, 246415 R, 246435 R

Abstract:

This invention is an electro-hydraulic system to automatically lubricate railroad switches and enhance their performance. The lubrication covers switch plates, switch rods, switch points, the base of stock rail adjacent to switch rail and the top of both switch and stock rails. Wear and tear of the switch rail and lateral creep force impact are thus reduced and the switch operates smoothly. Switch related derailments, rail fractures and maintenance labor will be reduced significantly. A pressurized tank with a microprocessor controller, placed on the wayside, supplies an environmentally acceptable smooth-flowing lubricant via hoses or pipes to two nozzle holders with check valves mounted with special brackets a short distance from the switch point on both rails. Lubricant is sprayed with one or more nozzles on each rail switch to cover all or part of the switch length. One or two solenoid valves in the flow lines control the quantity of lubricant applied in each shot and the frequency of application.

International Classification:

US Classification:

212271, 291 2

Abstract:

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.

Abstract:

A rail lubricator for a railroad rail has a nozzle adjacent to the rail and attached thereto. The nozzle has a discharge orifice disposed beneath the top surface of the rail. The orifice is aimed generally longitudinally of the rail with the aiming including an upward component and a lateral component toward the centerline of the rail. Jets of lubricant project upwardly from the nozzle, arch above the top surface of the rail, and then fall onto the top surface and gage corner of the rail. This lubricates the top of a rail using an optimum amount of lubricant on the optimum area of the railhead. The lubricant is applied when the nozzles are spanned by a car.

US Classification:

Abstract:

A process is provided for conversion of a feedstock, in particular a hydrocarbon feedstock such as methane or natural gas, in which a reactive mixture containing the feedstock is prepared and fed to a reaction zone. A reaction is initiated in the reactive mixture within the reaction zone so as to generate a conversion wave of increased temperature and pressure. The conversion wave is allowed to pass through the reaction zone, from where converted feedstock is recovered. An apparatus for carrying out the process is also provided. The process operates with a high conversion and selectivity to desirable products and is particularly suitable for the conversion of methane to carbon monoxide and hydrogen.
