Abstract: The connectivity and security of wireless handheld devices (HDs) can be leveraged to provide a presentation appliance (PA) such as a laptop with an ability to securely communicate with an enterprise's private network. A split-proxy server, with part of it executing on the HD and a part executing on the PA, implements a full HTTP 1.1 compliant Internet/Web Proxy to couple the PA for communication through the HD. Specifically, the split proxy provides support for the pragmatic keep-alive header, the CONNECT method, socket connection sharing, and thread pooling, to enable a fully functional browsing environment. Such an environment enables access to commercial web-based applications that are built on standard Internet technologies without the need for re-rendering or re-writing the user interfaces to suit the HD. In addition, Intranet web-based applications are made securely accessible without the need for additional VPN and remote access technologies.

Abstract: A medium and high pressure pump systems supplies a cryogenic fluid from a storage tank. The system comprises a pump that is operable to pump cryogenic liquid or a mixture of cryogenic liquid and vapor. The pump preferably comprises an inducer with at least two chambers and means for recycling excess fluid within the inducer instead of returning excess fluid to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

Abstract: A method and apparatus is provided for supplying both cryogenic liquid and vapor from a storage tank to a pump to reduce the need for venting. The pump is operable to pump cryogenic liquid or a mixture of liquid and vapor. Different operating modes are selectable to control mass flow rate through the pump. With one operating mode a high flow rate is achieved by supplying only cryogenic liquid to the pump. By selecting another operating mode, a lower mass flow rate is achieved by simultaneously supplying liquid and vapor from the storage tank to the pump. The pump preferably has an inducer with at least two chambers and valves for recycling excess fluid within the inducer instead of returning it to the storage tank. The reciprocating pump is preferably double acting such that fluid is discharged from the pump during both extension and retraction strokes.

Abstract: A fertilizer comprising at least one layered double hydroxide (LDH) compound containing at least one nutrient anion. In another aspect, the fertilizer comprising at least one clay material mixed with at least one nutrient cation. The fertilizer preferably comprises at least one layered double hydroxide (LDH) compound containing at least one nutrient anion and at least one clay material mixed with at least one nutrient cation. Methods for treating soil, for manufacturing the fertilizer and for enhancing plant growth are also described, as are soil conditioning agents and soil-less culture media.

Abstract: A medium and high pressure pump systems supplies a cryogenic fluid from a storage tank and methods of operating such systems to remove both liquid and vapor from the storage tank to reduce the need for venting. The system comprises a pump that is operable to pump cryogenic liquid or a mixture of cryogenic liquid and vapor. In accordance with the method, mass flow rate through the pump is controlled by selecting one of at least two operating modes. In a first operating mode a high flow rate is achieved by supplying cryogenic liquid to the pump from the storage tank to substantially fill a compression chamber within the pump with liquid. In a second operating mode, a lower mass flow rate is achieved by selectively simultaneously supplying liquid and vapor from the storage tank to the pump, with the vapor fraction being higher in the second operating mode compared to the first operating mode.
