Abstract: A system for allocating heterogeneous resources may include a client device, a plurality of heterogeneous resources, and a server host. The client device may be configured to request access to one or more specific resources, and the server host may be configured to allocate the requested resource(s) to the client device in response to the server host determining the availability of the requested resource(s). The client device may then establish direct and/or exclusive access to the requested resource(s) and communicate commands to and exchange data with the requested resource(s), bypassing the server host. The server host may also be configured to queue requests for unavailable resources and to later grant access to those resources upon those resources becoming available. Methods of allocating heterogeneous resources are also provided, as are other aspects.

Abstract: A chemical fluid valve transfer (e.g., load/unload) assembly is formed from a male valve assembly and a female valve assembly. The male valve assembly is fitted with a male connector which houses a chamber that is connected to a flush inlet line, and a flush outlet line, and a chemical transport line. The female valve assembly is fitted with a female connector which mates with the male valve assembly male connector for interconnecting the male valve and female valve assemblies, and fitted with a chemical transport line. Another aspect of the present invention is a method for transferring a chemical fluid between a tanker fitted with a female coupler and a fill/unload station fitted with a male coupler and hose assembly. This method involves the connecting of the tanker hose and the fill station hose with the valve assembly described above.
