Abstract: PCT No. PCT/FR93/00314 Sec. 371 Date Dec. 13, 1993 Sec. 102(e) Date Dec. 13, 1993 PCT Filed Mar. 30, 1993 PCT Pub. No. WO93/21474 PCT Pub. Date Oct. 28, 1993A fluid optical system for focusing all entering light whatever its direction and incidence, and having an entrance surface through which the light enters. The optical system has a volume having an optical shape generated by a logarithmic spiral so that the focusing occurs for light beams entering the entrance surface from any direction through any point of the entrance surface. There flows in the optical shape a fluid which is maintained in forced circulation to form a fluid optical system, and which is forced to enter the optical system tangentially to the optical shape and adjacent to the entrance surface which is arranged so that initial circulation is tangential and laminar. Inside the optical system, the fluid has a centripetal rotation movement until it exits through a cone end of the optical shape, thus draining off calories.

Abstract: A pressure test and bypass valve for use in well testing.      The apparatus comprises a housing defining a central opening therein and a mandrel slidably disposed in the central opening.      A ball valve allows fluid flow through the central opening when in an open position and prevents fluid flow therethrough when in a closed position. A sleeve valve allows communication between the central opening and a well annulus when in an open position and prevents communication between the central opening and the well annulus when in a closed position. The ball valve and sleeve valve are actuated substantially simultaneously in response to well annulus pressure. A rupture disc is ruptured due to differential pressure thereacross. This allows well annulus pressure to act across a differential area on the mandrel such that the mandrel is moved relative to the housing, thereby actuating the valves.

Abstract: A masking tape is provided that is suitable for insertion under many moldings and gaskets which not only masks the molding or gasket but also facilitates refinishing under at least a portion of the molding or gasket. The masking tape is constructed to include a longitudinal non-adhesive portion and a longitudinal adhesive portion, wherein the non-adhesive portion is stiffer than the adhesive portion and is sufficiently stiff to facilitate easy insertion of the non-adhesive portion beneath at least a portion of the molding or gasket to be masked while the adhesive portion is sufficiently flexible to permit the wrapping thereof around the molding or gasket. The stiffened portion advantageously provides a dual purpose of facilitating the easy insertion of the non-adhesive portion beneath the molding or gasket and creating a lever action during application between the molding or gasket and the wall or panel to which the molding or gasket i s mounted. This lever action creates a force which tends to separate or lift an edge of the molding or gasket from the wall or panel to open the wall or panel under the molding or gasket for refinishing. The masking tape is especially applicable for masking flexible gaskets that include a leg portion that overlies an adjacent panel that is to be refinished.

Granted: 2001-07-03
Abstract: The present invention relates to a portable modular drainage system that is attached to a series of cylindrical planting containers. The system comprises a plurality of peaked modules with opposing, convergent curved side walls designed to conform to the curve of a planting container. Between each side wall is a notch which accepts one or more containers and firmly connects the module to the containers. The modules are preferably designed in four distinct shapes, one with quadrature symmetry for connecting four containers at once, one smaller triangular unit which connects three staggered containers, one three-legged unit that connects two containers which are positioned at an edge of a plant farm, and one edge unit designed to connect three staggered containers at the end of three rows. When these modules are appropriately connected to the containers, they effectively drain the water that would otherwise have fallen between the pots directly into the pots. Not only does this system save up to 20% of water that would otherwise be lost between containers, but it also prevents unwanted weed and grass growth between the containers by depriving it of water, and helps to prevent the containers from being blown over.

These circuitry and complementary logic support a hierarchical view of the serial bus elements (16), logically dividing the hierarchy into multiple tiers. This logical view of the serial bus elements is used by the bus controller to detect the presence of interconnected serial bus elements and the functions of the bus agents, i.e. the system unit and the interconnected peripheral, as well as assignment of addresses to the serial bus elements and the functions, at power on, reset, and during operation when serial bus elements are hot attached to or detached from the serial bus assembly.
