Title: Flow injection analysis of total inorganic phosphate
Inventor: O'LEAR CHRISTINA
IPC: G01N35/08
Filed: 1991-10-15
Abstract: A method for flow injection analysis of total inorganic phosphate contained in an aqueous system such a cooling tower or boiler is described which uses a reducing agent and preservative composition therefore as the carrier for he sample to be analyzed, thereby creating a facile process which permits conversion of the various polyphosphates to orthophosphate and development of the molybdenum blue complex color reaction at 60°-95°C and under 2-10 psi. This method has less stringent pressure and temperature requirements than those employed heretofore, thus permitting the use of more reliable and economic devices for measuring total inorganic phosphate in the field.

Patent CA-2065467-A1 (CA)
Inventor: MCCORD THOMAS H
IPC: B01D53/18
Filed: 1992-04-07
Abstract: A process and apparatus for removing SO2 from low-volume gas streams containing high concentrations of SO2 includes a tank scrubber containing an aqueous SO2 absorbent and an impeller. The impeller includes a vertical rotating shaft having an upper and lower impeller. The lower impeller serves to agitate the SO2 absorbent. The upper impeller include a shroud thereby directing the absorbent and gas outwardly toward the wall of the scrubber. The gas is injected into the absorbent at a point below the shrouded impeller. The shroud prevents gas bypass and thereby promotes gas-liquid mixing and, consequently, markedly improves SO2 removal efficiency.

Title: Levelled Cement Spreader
Inventor: VALENTE PIETRO
IPC: E04G21/20
Filed: 1992-04-15
Abstract: The present invention relates to an apparatus for applying cementitious material onto a floor surface while  screeding  it and producing varying  depths  of ridged impressions in a longitudinal direction within the cementitious material,  from deep ridges to flat surfaced material, all formed with a levelled surface, adapted to receive tile components and other flooring products.   The apparatus includes a base adapted for displacement on the floor surface and provided with a container to receive the cementitious material.   The container is adapted to discharge a required amount of cementitious material on the floor surface.   The base defines an opening which screeds the material onto the floor surface and trails the discharged cementitious material from the container on the floor surface when the apparatus  is operatively displaced.   A gate is moveably mounted to be vertically displaced for selec-tively reducing the opening and for evenly spreading the  cementitious  material  passing  therethrough.    A plurality of spring loaded fingers mounted onto the front of the base are biased to abut onto the floor surface and are adapted to scrapingly remove levelled discharged cementitious material in operation of the apparatus for forming spaced apart channels substan-tially free of cementitious material  or varying  in depth up to a flat surface.
