Abstract: A peripheral unit for use in a water regulation system that controls the intake of water in a water circulation system of a building; it has a power source; a user input interface; a motion detector; a communication interface that is configured to establish a connection with the control panel; and a controller that is configured to send a first transmission to the control panel via the connection for causing the controller of the control panel to actuate opening of the water valve for a given period of time; and send a second transmission to the control panel via the connection for causing the controller of the control panel to actuate closing of the water valve.

Abstract: The subject invention provides a lighting system with a light source, a plurality of spokes to house the light source and a structural hub adapted to connect to the plurality of spokes. A method of using the lighting system includes connecting the plurality of spokes to the hub, emitting light from the light source housed within the plurality of spokes and connecting the hub to an electrical connection housing.

Abstract: A LED Lighting fixture including a first and a second heat sink section made of high thermal conductivity material and a LED assembly. The first heat sink section includes a closed outer wall defining a housing cavity; and a plurality of first projections projecting inwardly into the housing cavity. The second heat sink section is engageable and securable with the first heat sink section and includes a LED support including a LED engaging wall and a plurality of second projections projecting from an inner surface thereof. At least one of the second projections physically engage a corresponding one of the first projections to define a thermal bridge therebetween, when the first and second heat sink sections are engaged. The LED assembly is engageable with the second heat sink section and is in thermal engagement with the LED engaging wall thereof when engaged with the second heat sink section.

Abstract: Process for manufacturing alumina trihydrate by alkaline attack of bauxite, following the general steps of the Bayer process, and during which, after settling and before decomposition, the aluminate liquor undergoes a filtration, known as security filtration, so that at the end of the filtration it contains less than 10 mg/l of insoluble particles, characterized in that, during said security filtration, a filtration device is used that comprises a zone in which the liquor is subjected, after passing through said filtration media, to a pressure greater than 2 bar, preferably greater than 3 bar. Preferably, this device also comprises a zone in which the liquor is subjected, before passing through the filtration media, to a pressure greater than 5 bar, preferably greater than 6, typically in the vicinity of 7 bar. In this way, the aluminate liquor can be kept at a high temperature during the security filtration, typically greater than 130° C., preferably greater than 140° C.

Abstract: The invention relates to a reactor for the treatment of wastewater solutions containing cyanide and other dissolved organic material, having an elongated tube having an entrance (28) and an exit (32), and an energy source (22) for the tube, preferably positioned adjacent the exit. The energy source generates intense energy such that a cyanide/organic material-containing solution can be treated by passing it through the tube to expose it to said energy so that the solution absorbs sufficient energy from the energy source to degrade the cyanide and/or dissolved organic material contained therein. The source of intense energy is preferably a plasma, e.g. a plasma generated by a plasma torch or a DC electric arc. The invention also relates to a process of treatment of such a wastewater solution by passing it through such a reactor.
