Abstract: La condition d'étanchéité d'un stockage souterrain de produits liquides ou gazeux -hydrocarbures par exempleconsistant en une ou plusieurs cavités creusées dans un massif perméable saturé d'eau est que ce stockage soit situé à une profondeur H sous la nappe phréatique telle que: H > P + F P: pression du produit stocké F: paramètre de forme, chacun des trois termes étant exprimé en hauteur d'eau. La présente invention permet: -de déterminer la pression maximale admissible pour un produit donné dans le cas d'un stockage dans un vide déjà existant; -de déterminer la géométrie d'un stockage à créer (profondeur, forme de la ou des cavités) pour éviter toute migration du produit stocké dans le massif rocheux. Il est connu de rétablir au-dessus de stockages réalisés dans des massifs rocheux mal alimentés le potentiel hydraulique de la nappe en réalisant un certain nombre de forages dans lesquels on peut ou non injecter de l'eau, qu'il est commun d'appeler rideau d'eau, La condition précédemment énoncé demeure inchangée, mais le paramètre de forme se trouve diminué du fait de la présence de cet ouvrage de réalimentation.

Abstract: A B S T R A C T A process for recovering and using fines of flux, such as limestone, used in a metallurgical process, such as oxygen steelmaking, is described.  The process involves collecting fines from a receiving zone, e.g., with blower and baghouse equipment.  The fines so collected are then conveyed, as by a dense-phase conveyor, to a first pro-cessing zone containing a first screening means for screening flux material which is to be fed to the process. Material not passing through said first screening means is fed to the metallurgical-process vessel, but fines passed by the first screening means are collected and formed into briquettes.  The briquettes are conveyed to a second processing zone which is located above the conveyor which leads from the receiving zone to the first processing zone mentioned above.  The second processing zone contains a second screening means and means for storing and releasing to the said conveyor the briquettes or portions thereof which have not passed through said second screening means. In particular, the second screening means serves to remove from the briquettes their flashings, which pass via the conveyor and the first screening means to the briquetter and are thus recycled and recovered.

Abstract: BLOWOUT PREVENTER Abstract A blowout preventer comprises a housing with a pair of opposed rams carrying sealing blocks for sealing against tubing extending through the housing.  Openings in the front side of the housing provide access to the sealing blocks for changing the blocks and a door closes the openings during normal in-service use of the preventer.  A door guide permits the door to be slid in either of two opposing edgewise directions for exposing the openings one at a time but keeps the door from being movable substantially in a broadwise direction.  Sealing inserts disposed within the openings between the door and the sealing blocks serve to seal against leakage and a rack and pinion mechanism provides the means for sliding the door from a centered position closing both openings to opposite edgewise positions exposing one or the other of the openings.

Abstract: ABSTRACT OF THE DISCLOSURE     A low cost high frequency electronic dimming ballast for gas discharge lamps is disclosed which elim-inates the need for external primary inductance or choke coils by employing leakage inductance of the transformer.          The system is usable with either fluorescent or high in-tensity discharge lamps and alternate embodiments employ the push-pull or half-bridge inverters.  Necessary leakage inductance and tuning capacitance are both located on the secondary of the transformer.  Special auxiliary windings or capacitors are used to maintain necessary filament heating voltage during dimming of fluorescent lamps.  A clamping circuit or auxiliary tuned circuit may be provided to prevent component damage due to over-voltage and over current if a lamp is removed during operation of the system.

Abstract: Abstract of the Disclosure An improved opthalmic lens for presbyopia is disclosed in which the refractive power is progressively changed to provide a natural visual target arrangement.          In the opthalmic lens, rotation of the head of a wearer for binocular lateral vision is taken into account to permit comfortable binocular lateral vision closer to vision with the naked eyes.  Two refractory surfaces are provided one of which includes a vertical first umbilical meridian curve dividing the surface into two lateral areas closer to the nasal side and temporal side respectively and assymetric with respect to one another.  The surface is such that when a second meridian curve is imagined to contact the first curve then the first curve is displaced towards the nasal side in a lower region of the refractory surface and is displaced but less so towards the nasal side in an intermediate region of the surface.

Abstract: ABSTRACT OF THE DISCLOSURE    A method and apparatus for injection molding arti-cles from a thermoplastic or similar material.  A plural-ity of molds are mounted on a turntable and are indexed to selected positions as the turntable rotates about its axis of rotation.  Radial slots divide the turntable into sec-tors, each having a mold thereon.  A clamping mechanism is provided which successively deflects each sector slightly from the plane of the turntable in order to precisely align the mold thereon with an injection nozzle and then securely clamps the halves of the mold together while the injection nozzle injects moldable material into the cavity in the mold.  Interchangeable cavities with different size and shape characteristics are provided in the injection molds and associated with each mold is a resettable indi-cator designating the particular type of cavity presently installed in that mold.  A sensor unit responsive to the indicators provides a control unit with an indication of the characteristics of the cavity in each mold when it is aligned with the injection nozzle and the control unit ad-justs the parameters of the injection operation to cor-respond to those characteristics.  In one embodiment, two injection nozzles are provided and an annulus is inserted into each mold cavity to separate the cavity into two por-tions, each of the nozzles injecting moldable material into a respective one of the cavity portions.

Abstract: ABSTRACT OF THE DISCLOSURE           A fixture for clamping two abutting pipe sections together while they are being welded, including an expandable section com-prising a plurality of longitudinal segments arranged to nest together and form a central bore, a spring member encircling the nest of segments to retain the segments yieldingly in their nest-ing relation to each other, a first body having an internal bore aligned with that of the nested segments and providing a conical wedge surface inclined in the direction of the nest, and a second body having an internally threaded bore aligned with the bore of the nested segments and providing a conical wedge surface inclined in the direction of the nest, whereby the movement of the first and second bodies toward the nest engages the nest with their conical wedge surfaces to overcome the spring force to radially move the segments from their bore.  A threaded rod extends through the axially aligned bores of the first body and the bore of the nest to bring a shoulder on the threaded rod against the first body and into threaded engagement with the second body.  Means is provided for preventing rotation of the second body.  Means is provided for rot-ating the threaded rod in its engagement with the second body threads whereby rotation of the threaded rod in its engagement with the threads of the second body moves the first and second bodies toward and away from each other to alternately expand and contract the expandable section.  A sleeve member with a bore sized to journal the sleeve freely over the threaded rod comprises means for axially spacing the sleeve member from the expandable section, and a shoulder formed on the sleeve member is sized to engage the non-abutting end of one of the pipes.  Means is provided for fixing the axial position of the sleeve member along the threaded rod to engage the pipe and sleeve shoulder to bring the other end of the pipe to its junction with the end of the second pipe, and passage-ways are formed through the sleeve member to establish a flow of inert gas through the pipes.
