Abstract: The disclosed technology offers methods of updating a data cube of samples and a display on a client device with a processor. The method provides GUI clients to computer devices; receives initial reports of sample values organized by sampled computing device and sampled aspect of operations, and identified by group membership and super-group membership; receives, from the devices, samples that update reports of sampled aspects of operations; and pushes updated reports to the GUI clients. The GUI clients calculate and update group and super-group aggregate operational status; and display a hierarchical representation of the aggregate operational status of the super-groups and groups and of the operational status of the computing devices, based on the sample values, in real or near real time, as received samples reach the clients. The operator viewing the display of the hierarchical representation is notified of operational aspects that require close monitoring or immediate remedial attention.

The high aspect ratio in one embodiment is substantially 20:1.

Abstract: The invention provides a method for the direct preparation of pure warfarin sodium from warfarin acid. The reaction is conducted in a polar organic solvent, preferably ethanol, using a volatilizable base, preferably sodium bicarbonate or sodium carbonate, at low temperature. Drying the final product is accomplished at low temperature to avoid decomposition of the final warfarin sodium product.

Abstract: A vortical-type separator for removing from the gas stream suspended particulates present in the gas stream has an internally generated scavenging gas flow and a pulse jet system for cleaning scavenging gas filter elements. The separator has two or more conduits that are coaxially positioned with an annular clearance at their ends. A gas swirl device creates a swirling motion, causing heavier particulates to be discharged out the annular clearance or ejection port into a scavenging gas plenum. A flow path is created between the scavenging gas plenum and the outlet of the separator, with the pressure differential between the outlet and the ejection port causing scavenging gas to flow to the outlet. A frame is mounted in the flow path over which a bag filter is secured. The dust-laden scavenging gas flows through the bag filter and out the outlet. A nozzle is positioned at the mouth of the bag filter for periodically discharging a pulse of clean gas into the bag filter reverse to the flow of the scavenging gas.

Abstract: A separator is disclosed for removing from a gas stream suspended particulates such as liquid droplets and finely divided solids. A housing chamber encloses a tube that contains a gas swirl device for imparting a swirling motion to the gas stream entering the inlet of the tube. A separator conduit is axially aligned with the tube and has its upstream end coaxially located in the downstream end of the tube, defining an annular ejection port. Suspended particulates and scavenging gas are discharged into the chamber through the annular ejection port. The downstream end of the separation conduit is in communication with the outlet of the housing. A passage is provided for returning the scavenging gas to the main gas stream at the outlet of the housing. A separation device is located in the passage to cleanse the scavenging gas of suspended particulates prior to recombination with the main gas stream.

Abstract: An apparatus for applying colored lines on ice, in which a roller can be moved over ice in a positive and controllable manner, is provided with at least one wheel having a multiplicity of small protrusions or points on its peripheral surface. The protrusions on the tread of the wheel dig into the ice to give easy traction and thus ensure proper rotation of the roller without undesired swerving slippage.
