Title: Use of silver to control iodine level in electrodeless high intensity discharge lamps
Inventor: CHANG HSUEH-RONG
IPC: H01J61/82
Filed: 1994-08-18
Abstract: USE OF SILVER TO CONTROL IODINE   LEVEL IN ELECTRODELESS HIGH       INTENSITY DISCHARGE LAMPS                      Abstract Silver is added to the fill of an electrodeless high intensity metal halide discharge lamp, which includes at least one metal iodide as a fill ingredient, for controlling the iodine vapor level therein.  In operation, silver reacts with free iodine, forming silver iodide (AgI), which has a relatively high boiling point and a relatively low vapor pressure.  The iodine level is thus controlled below an arc instability threshold to promote and maintain arc stability.  In addition, silver does not attack the quartz arc tube wall because silica (SiO2) is much more stable than silver oxide (Ag2O). Moreover, the addition of silver to the arc tube does not accelerate the decomposition of iodides in the fill, such as sodium iodide (NaI), cerium iodide (CeI3), lanthanum iodide (LaI3), neodymium iodide (NdI3), and praeseodymium iodide (PrI3), which would otherwise enhance devitrification and etching of the quartz wall.  Lamp performance and life are thus substantially improved using silver as an iodine getter.
Patent CA-2131287-A1 (CA)
Title: Refractory protective coatings, particularly for electrolytic cell components
Inventor: SEKHAR JAINAGESH A
IPC: C04B41/89
Filed: 1993-04-01
Abstract: An adherent protective coating (9) of a refractory material is produced on the surface of carbonaceous, refractory, ceramic, metallic or other materials serving as components of electrolytic cells operating at high temperature, by applying to such surfaces a well chosen micropyretic reaction layer from a slurry, which when dried is ignited to initiate a self sustaining micropyretic reac-tion, along a combustion front, to produce condensed matter forming such refractory protective adherent coating. The slurry is preferably applied in several layers, the first layer(s) to facilitate adherence and the last layer(s) to provide protection, and may contain some preformed non-reactant materials. The electrolytic cells whose components require such coatings are especially those operating at high temperature with a molten salt electrolyte, particularly those for the production of metals, aluminium be-ing the most important. For these cells the invention provides an aluminium-wettable, adherent, refractory, protective coating (11) for the cell-bottom carbon cathode (4), containing RHM material such as titanium diboride, as well as other refractory protective coatings for cell wall lining (2) and for other cell components. Novel cell designs far the utilization of the different coatings are also provided.

Title: Deep bed sand filter
Inventor: WARD STEPHEN D
IPC: B01D24/30
Filed: 1993-05-04
Abstract: A deep bed upflow filter (10) for removing suspended solids from an influent stream to provide a clean filtrate, comprising an upright vessel (12) having a vertical axis (14), top and bottom ends (16,18) and contiguous upper (20), lower (22), and intermediate (24) regions between the ends. The upper region contains filtrate (26) up to a first elevation (28) and an outlet (30) for drawing the filtrate out of the vessel. The intermediate region contains particulate filter media (32) for removing the suspended solids from influent moving upwardly through the media as the media, dirtied with solids, moves downwardly into the lower region. The lower region is generally tapered (36) inwardly toward the vessel bottom and contains dirty media (34) that has moved downwardly from the intermediate region. Influent is introduced (44) between the intermediate and lower regions, and the dirty media is collected (46) at the bottom and transported (50) to a regenerative washing compartment (52). A portion of the reject flow (64 ) from the wash compartment is delivered (72,74) to the dirty media in the lower region of the vessel and another portion (72,78) is delivered to the area (46,48,50) where the dirty media is collected and transported. This latter portion is preferably introduced into a collection conduit (46) through a pipe (130) having a concentric inner tube (140) by which air is injected to fluidize and move the mixture of air, dirty media, and reject water in the conduit (46) toward an airlift (48,148).
