Abstract: A system for detecting and indicating variations in volume of chemicals in a container is provided. The system includes a retention basin configured to retain the container. The retention basin includes a pressure cell, a basin input interfaces, and a basin controller. The pressure cell is configured to measure a weight of the container. The container is placed on the pressure cell. The basin input interface is configured to allow specification of properties of the chemicals in the container. The basin controller is configured to calculate the volume of the chemicals in the container based on the measured weight of the container and the specified properties of the chemicals in the container. The basin controller includes a basin display configured to display the calculated volume of the chemicals in the container.

Abstract: A fluid collection and disposal device for a transfer cart used for transporting wet articles is comprised of a tray disposed below articles to be transported on a transfer cart. The tray has a drain opening. A conduit extends from the drain opening to an exterior side of the transfer cart. A valve assembly is connected to the conduit for controlling fluid flow through the conduit. The valve assembly is comprised of a valve element moveable between a closed, first position restricting flow of fluid through the conduit and an opened, second position allowing flow of fluid through the conduit. An actuator is provided for moving the valve element from the closed position to the open position. The actuator is moveable by physical engagement with an external stop.

Abstract: A method of dehydrogenating a hydrocarbon, especially an alkane, to form an unsaturated compound, especially an alkene, includes contacting the alkane with a catalyst including a form of carbon which is catalytically active for the dehydrogenation reaction. The catalyst may be formed by passing a hydrocarbon over a catalyst precursor at an elevated temperature for sufficient time to form the active carbon phase, characterized in that the catalyst precursor includes less than 0.1% of a transition metal.

Abstract: Apparatus for the purification of the liquid metal for cooling the core of a fast neutron reactor comprising a heat insulating envelope immersed in the reactor core and suspended from the protective slab surmounting the latter, a removable plug disposed in said slab and giving access to the upper part of the inside of the envelope and, within the latter, a cooling coil for cooling a liquid metal flow taken from the reactor core to a temperature which ensures the solidification of impurities, a filter cartridge for filtering the cooled liquid metal, a heat exchanger for the at least partial heating of the purified metal prior to its return to the reactor core and a valve for regulating the purified metal flow returned to the core, wherein it comprises a passage for returning to the upper part of the envelope purified metal from the filter cartridge, the purified metal being returned to the reactor core with the purified metal in heat exchange with the metal to be purified in a regulated flow, the regulating va
