The brake apparatus further includes a relay valve that operates the brake apparatus in response to the first control pressure received from the standard load valve.   The penalty brake design comprises a penalty check valve, a penalty load valve and a third mechanism for providing a penalty brake control pressure in response to a command for penalty braking.   The penalty load valve provides in response to the penalty control pressure received  from the  third mechanism a  second brake cylinder control pressure that is proportional to weight borne by the rail vehicle.  The penalty check valve conveys the higher of the first and second control pressures received from the two load valves to the relay valve to operates the brake apparatus.

Granted: 2000-12-05
Abstract: Systems, methods and computer program products enable framework building by interactively generating a framework corresponding to a design and editing the interactively generated framework to obtain a completed framework. The framework is displayed in various stages of construction or modification using a number of different views including a tree view, a graph view, a method view and an edit view. In addition, parts of the framework are identified as requiring completion, as completed, and as permitting completion. Still further, user methods and framework methods are differentiated. Help guided actions are provided and may be invoked to assist in the development process. Once the framework has been completed, it can be stored in a data model, and code can be generated from the completed framework. Finally, interfaces developed using conventional editors may be parsed and imported into the data model for later code generation. As a result of the present invention, code may be generated based on the completed framework and executed in a distributed computing environment.
