Abstract: A travel application for a mobile device is described. The travel application can include an application database which resides on the mobile device and application code for processing instructions stored in the application database, such as instructions for creating pages of information output via the travel application on the mobile device. Without recompiling or reinstalling the travel application on the mobile device, via updates to the travel application database, the navigation structure of the travel application can be changed, a travel data section can be added or removed, a filter for an existing travel data section can be added or removed and the output structure for any of the plurality interface states associated with the travel application can be modified. By executing from an application database stored locally on the mobile device, the travel application can provide some amount of guaranteed functionality when network access is unavailable.

Abstract: Fragile agglomerates with crushed rock fragments, such as fines which are subsequently agglomerated and which result in the crushing of rock fragments, such as oil shale prepared for retorting are mixed and delivered onto conveying means, such as a travelling grate by charging the rock fragments into a bin which delivers through a choke-feed onto the conveyor or travelling grate by introducing the agglomerates through a series of space conduits or tubes terminating inside the bin below the level of the lump material or fragments in the bin where the rock fragments have a downward travel such as to enable the aggregates to diffuse from the ends of the spaced pipes into and through the fragments and while so separated and diffused through the fragments move with the fragments onto the grate.

Abstract: In a process for the removal of fines from a bed of oil bearing shale in a travelling grate retort, a fluid such as air, inert gas or process gas is drafted through the bed in order to entrain in the fluid substantially all of the fines in the bed. The fines are then evacuated from the bed thus increasing the permeability of the bed and substantially decreasing the fines in the retorted shale oil.
