Patent CA-2162062-A1 (CA)
Title: Power System Compensator Apparatus and Power Converter Apparatus
Inventor: AKAMATSU MASAHIKO
IPC: H02J3/18
Filed: 1995-11-03
Abstract: A  power  system  compensator  apparatus  comprising  a  power converter unit that works in series with the transmission of a power system and switching control means for controlling the link voltage (VL I N K ) of the non-power system side.  The switching control means controls the phase of, at least, the fundamental  frequency  of  the  power  system.    The  power converter unit contains a static power converter transformer with phase differences taking place the secondary windings of the power converter unit.   The static power converter unit  is operated in non-PWM or  fixed pulse width ratio.          Switching rate is minimized.  Loss is lowered while economy of operation is improved.  Since the voltage that works in series  with  the  power  transmission  line  is  controlled, direct compensation of system reactance voltage and direct control of line current are performed.  Improved performance thus results.

Title: Method for protecting a porous carbon-containing material from oxidation and material obtained thereby
Inventor: DELAVAL RODOLPHE
IPC: C03C3/21
Filed: 1995-04-05
Abstract: The material is impregnated with an aqueous solution containing the precursors of a phosphate glass base modified by at least the presence of zinc oxide, dried and heat treated to form an internal anti-oxidative coating comprising the modified phosphate glass base. The precursors are fed into the aqueous solution so as to form a glass base wherein the molar ratio of the glass modifying oxides, including zinc oxide and glass-forming oxides, consisting of mainly or only phosphoric anhydride, is sufficiently high, particularly 0.6 or over, preferably 0.9, to make the phosphate glass base resistant to moisture corrosion. The solution is obtained by initially dissolving in water a polyphosphate such as sodium metaphosphate or trimetaphosphate capable of subsequently stably solubilising, by complexing, and without precipitate formation, the required amount of precursor salts of the modifying oxides, comprising at least one zinc salt such as zinc nitrate or sulphate.

Abstract: The present invention relates to extensible endless conveyor belt support structures and systems. A support structure has vertical support members (8) connected by V-shaped arrangements of pivotally connected (17, 19) link members (7, 9). By mounting at least the upper belt run rollers (4) on the vertical supports (8) the load can be more effectively supported whilst providing a relatively high ratio of extended to contracted length. By using telescopically extendable (14, 15) vertical supports (8), any increase in overall height of the support structure upon contraction thereof is minimized or avoided. By also having detachable lower belt run rollers (23) the support structure can be inserted into an endless conveyor belt installation without dismantling or even stopping running thereof. The invention also provides systems including settling devices for holding the support structures in their contracted form and deploying and collecting them into and from their extended conditions. Preferably the setting device includes a retractor means for drawing in the support structure during collection thereof.
