Patent CA-2063034-A1 (CA)
Inventor: KROON DAVID H
IPC: B65D90/46
Filed: 1992-03-13
Abstract: The invention relates to a cathodic protection system for an above-ground storage tank having a metal bottom, (20) both new and retrofitted bottoms. A leak containing dielectric safety membrane (25) is spaced a short distance below and extends beneath the tank bottom generally parallel thereto forming a narrow envelope. Compacted electrolytic conductor (28) is positioned between the membrane and the tank bottom supporting the tank bottom embedding a horizontally disposed cathodic protection anode (30), the anode being in the form of a matrix or grid of interconnected titanium bars and ribbons (32). A reticulate dielectric insulator (48) may be embedded in the electrolytic conductor and positioned directly above the anode and such insulator is operable to keep any portion of the anode from contacting the tank bottom and to maintain a generally uniform spacing between the anode and tank bottom. The ribbons extend transversely of the bars and are spot welded on uniform centers to bars on diameters or major chords of a circular tank bottom. A low profile connection (37) is provided between the bars and power feeds to a rectifier, (42) and for large tank bottoms a multiplicity of such connections strategically spaced are provided. Similarly, a plurality of reference cells (34) both in location and kind may be provided so there are redundant power feeds and reference cells. The anode is constructed by uncoiling, arranging and connecting the bars and ribbons on a compacted layer of electrolytic conductor on the liner. After the conductors are attached and routed to the external rectifier, the insulator may be placed above the anode grid. Further compacted electrolytic conductor fills the openings in the insulator.   <IMAGE>

Filed: 1992-09-14
Abstract: In video signal processing a gradation correction apparatus for processing R, G, and B input signals includes a luminance signal conversion device for obtaining the original luminance signal, which is before gamma conversion, from the input signals, and a luminance gamma conversion device for gamma converting the original luminance signal to desired gradation characteristics to obtain a gamma converted luminance signal.  The ratio of the gamma converted luminance signal to the original luminance signal is obtained, and this ratio is multiplied by each of the R, G, and B input signals for obtaining primary gradation-corrected R, G, and B signals. The difference between each of the R, G, and B input signals and the original luminance signal is obtained and the gamma converted luminance signal is added to each of these differences for obtaining secondary gradation-corrected R, G, and B signals.  Final gradation-corrected R, G, B signals are obtained based on the primary and secondary gradation-corrected R, G, and B signals.  The result is a system in which effective brightness adjustment is possible within the dynamic range of the image, without changing its hue or saturation characteristics.

Le dispositif se compose d'un anneau ferromagnétique entourant un noyau magnétique monté flexible et suspendu à son intérieur. Un courant électrique à différentes fréquences est appliqué à des bobines enroulées et montées à l'intérieur de l'anneau. Le noyau produit à l'intérieur de l'anneau un champ magnétique qui définit ses coordonnées par rapport à l'anneau et à ses bobines, et réagit avec le courant appliqué aux bobines pour produire un couple. La monture flexible qui suspend le noyau à l'intérieur des bobines permet le déplacement relatif entre ces éléments en réaction aux variations de courant. Le déplacement du noyau peut être utilisé pour positionner les éléments optiques. Dans un mode de réalisation, un miroir est monté sur le noyau et un faisceau laser réfléchi par le miroir produit toute une variété de motifs de balayage bidimensionnels. La forme des motifs est déterminée par la sélection des fréquences du courant appliqué aux bobines.

Inventor: BALAKRISHNAN ANNAPURNA
IPC: H04M3/42
Filed: 1993-10-27
Abstract: This invention relates to the minimizing of call set-up time for calls requiring the use of service circuits provided from a separate switching system, such as a service circuit node (SCN). Groups of semi-permanent circuits through a public switched telephone network (PSTN) are allocated to each of the switching systemsserved by the SCN. Thus, whenever a switching system has a call that requires the use of a service circuit housed in the SCN, the connection is already established. Traffic is controlled by limiting the size of the semi-permanent circuit groups, but these groups can be made larger or smaller, up to some overall total for the SCN, as traffic to each switching system changes. Advantageously, this arrangement permits efficient use of a large group of service circuits at the SCN, while minimizing the total call set-up time.
