Abstract:
a real-time control system having a fixed loop time is provided. The system includes an input having frequency ranging both above and below the fixed loop time; and a method for utilizing information provided by a pulse wheel and sensed by a sensor. The method includes the steps of: providing a rotating shaft; providing a pulse wheel rigidly affixed onto the rotating shaft; providing a sensor sensing an information out of the pulse wheel, the sensed information comprising a first information and a second information; and when the rotating rate of the rotating shaft is greater than a predetermined value, averaging at least two pulses wherein one of the at least two pulses being related to the first information and at least one pulse being related to the second information; thereby, the second information is used along with the first information for a more accurate representation of the information.
Abstract:
Apparatus for indicating the condition of hand brakes on railway cars and for applying and releasing railway car parking or hand brakes automatically in response to predetermined conditions including movement of a train, wayside conditioning apparatus, wayside operating mechanism, a signal controlled by an operator and performance of predetermined railway operating procedures, such as completion of an air brake test procedure. The apparatus may respond to mechanical, electrical and electronic signals and may operate on pneumatic or electric power provided from the service air brake system of a train or from a source of power outside of such air brake system.
Abstract:
A method that provides increased flexibility to measure dynamic range of a rotating system is provided. The method includes the steps of: providing a first rotating member; providing a second rotating member suitably engaged to the first rotating member; providing a set of sensors disposed to sense variations in characteristics along a circumference of the first member and the second member respectively; providing a controller for receiving information sensed by the sensors; determining a rate of rotation of the rotating members; selectively using the sensed information thereby at different rate of rotation different amount of the sensed information is used.

Abstract:
A pipe insulating section includes a generally cylindrical hollow phenolic foam body of substantially uniform cross section with an inner facing web and an outer facing web. The phenolic foam body is slit longitudinally to provide section halves which can be opened to facilitate wrapping around a pipe to insulate the pipe. The section halves are linked by the outer web at one side and facing ends of the section halves at the other end are faced with the inner facing web. The inner web may be of paper and the other web may be of an aluminum foil. An apparatus used in manufacturing the elongate shaped phenolic section includes an outer mold for forming the outer facing into a cylindrical shape and an inner mandrel for forming the inner facing into a cylindrical shape, which is of smaller diameter than that of the cylinder defined by the outer facing. The facings define a hollow core therebetween into which liquid foam reactants are injected through an injector.
Abstract:
A system and method that provides a message engine to facilitate intra-day receiving of first data relative to the trade transaction on behalf of one party to the trade transaction, wherein the first data include a code identifying an opposing party to the transaction; sending a message to the designated opposing party prior to submitting the trade transaction for matching prior to end-of-day clearing; and monitoring a message queue for a response and sending a message to at least one of the parties based on the response.
Abstract:
A pipe insulating section (1) comprises a generally cylindrical hollow phenolic foam body (2) of substantially uniform cross section with an inner facing web (3) and an outer facing web (4). The phenolic foam body (2) is slit longitudinally to provide section halves which can be opened to facilitate wrapping around a pipe to insulate the pipe. The section halves are linked by the outer web (4) at one side and facing ends of the section halves at the other end are faced with the inner facing web (3). The inner web (3) may be of paper and the other web (4) may be of an aluminum foil. An apparatus used in manufacturing the elongate shaped phenolic section comprises an outer mould (10) for forming the outer facing (4) into a cylindrical shape and an inner mandrel (11) for forming the inner facing (3) into a cylindrical shape, which is of smaller diameter than that of the cylinder defined by the outer facing (4). The facings (3, 4) define a hollow core therebetween into which liquid foam reactants (20) are injected through an injector (25). INTRODUCTION

Abstract:
A system and method that provides intra-day confirmation of non-anonymous trade transactions made at an exchange includes the entry into a computer system of first data relative to the trade transaction on behalf of one party to the trade transaction, wherein the first data include a code identifying an opposing party to the transaction. A message is sent to the designated opposing party prior to submitting the trade transaction for matching prior to end-of-day clearing. The trade transaction is matched to second data relative to the trade transaction entered into the system based on identity between certain elements of the first data and the second data, and a confirmation is sent to at least one of the parties to the trade transaction.
