Abstract: After they have been washed out, cavities (4) in rock salt contain a large quantity of brine (8) at a temperature which is lower than the temperature of the surrounding formation (2). This means that the cavity cannot be sealed quickly because the brine will expand progressively as it heats up. The method of the invention serves to shorten the time period between the end of working the cavity for salt and being able to abandon the cavity finally from about 30 years to about 2 years. The method consists in injecting quantities of a mixture (12) into the cavity (4), the mixture being of greater density than brine (8) and being capable of setting, with equivalent quantities of brine (8) being returned to the surface, and then in keeping the cavity (4) open after it has been completely filled with mixture (12) for as long as it takes the rock salt (2) to creep and fill up the shrinkage voids which appear during setting of the mixture (12), after which the cavity (4) can be sealed.

Abstract: Articulation fittings for window casings which partially covers the dormant casing and openings according to Italian art include lower compass arms and upper articulation members which cause the top rail of the window casing to project from the dormant casing during window opening movement. To detach immediately the top rail of the window casing from the dormant casing and thus avoid a premature wear and tear of the sealing joints adhering to the window casing, the articulation fittings are provided with means, which at the very beginning of the opening movement, cause the window casing to follow a path having a vertical component while causing the top rail of the window casing to follow a path having a horizontal component.

Abstract: The invention relates to a device for fixing lenses in the bezel rims of a spectacle frame, allowing easy and repeated mounting and removal of these lenses on to and from the frame. The bezel of the frame rim has a concave polyganol shape in cross-section. A metal ring sets the lens definitively round its periphery and has a rounded convex external edge. As viewed in cross-section, the contact between this external edge and the bezel is therefore made at points when the ring/lens assembly is fitted in the bezel rim.

A detection panel (47) is disposed as an inside lining of the bottom panel (3) and is connected via its own rims (48, 49) to the side panels (4, 5), and a tunnel (52) is left between the bottom panel (3) and the detection panel (47), with said tunnel opening out into the ducting, close to a bend.

Abstract: A device for removing (i.e., suction, capture and trapping) vapors and products carried by the vapors, for placement above a system for cooking food products in water or oil, circulates the exhaust gases in a cyclone having cooled walls to cause cold-wall condensation of the exhaust gases over the flow path through the cyclone.

Abstract: The filter is particularly for implantation in the interior vena cava by sliding through a small sized catheter of type 7F, so as to arrest the migration of all thrombi of dangerous size. The filter comprises a flexible wire having been subjected to a primitive predeformation into first and second substantially flat superposed loops. The loops are substantially symmetrical respectively with regard to two axes which are substantially orthogonal and convergent at a center of the filter. These loops can be elliptic and inscribed in a square, thus providing four contact points with the venous wall, which are in two-to-two symmetry with regard to the center on the longitudinal axis of the vein, which gives the filter high stability in the vein.

Abstract: The invention relates to an upright positioning structure with a pushing bar applying the upright positioning and pushing effort to the sub femoral area (3) and more particularly the ischial-femoral angle (3) of the user, pressing against the ischial projections of the user's pelvis and providing a resistance to forward sliding during the lifting up movement, the buttock and lumbar region of the user remaining outside of the pushing bar and unsupported.This structure is particularly applied to armchairs or fixed or mobile seats.

Abstract: The invention relates to a tangential distributor for stoppers of a given length and diameter. The distributor comprises a pair of rotating coaxial plates separated by a vertical distance which is slightly more than one stopper diameter. Between these plates is formed a passageway between a central portion of the plates and a peripheral area. Properly aligned stoppers are removed from this peripheral area. A baffle is formed into the passageway to orient the stoppers and allow only those oriented tangentially to the plates to pass into the peripheral area. A guide around the peripheral area retains the stoppers in the peripheral area until they are removed. The plates may be rotated at variable velocities for control of the rate of removal and orientation.

Abstract: A method of geologically confining toxic industrial waste, the method consisting of: using a cavity (1) previously leached from a mass of rock salt (2), the cavity being initially filled with brine (5); incorporating the waste in a pumpable waste-containing mixture (10) of density greater than the density of the brine and suitable for setting once put into place; inserting a predetermined quantity of a buffer liquid (7) into the bottom of the cavity by means of a dip tube (8) positioned in a well (4) and in communication with the surface (3), the buffer liquid being immiscible both with the brine and with the waste-containing mixture, the density of the buffer liquid lying between the density of the brine and the density of the waste-containing mixture, and the buffer liquid including one or more halogen-containing solvents; inserting the waste-containing mixture into the cavity by the means of the dip tube while the bottom end of the dip tube is maintained within the previously inserted buffer liquid; and re
