Abstract: A well cutting tool, comprising a housing including a chamber, the housing having at least one nozzle, the chamber being loaded with thermite, and a gas-generating additive an ignitor such that when the ignitor is actuated to ignite the thermite, the gas-generating additive is caused to create an increase in pressure which discharges energised molten thermite from the chamber and out of the housing through the at least one nozzle.

Abstract: The device for ejecting a cork from a corkscrew includes a body in which a spiral is received. There is a tubular cradle housed in a housing to accommodate the spiral and a cork screwed in the spiral. The cradle is formed by a stationary sleeve secured to the body and a sliding sleeve, translatable relative to the stationary sleeve, between a position in which it is completely nested in the stationary sleeve and a position in which it is at least partially removed from the stationary sleeve. Each sleeve has an upper end and a lower end, and the sliding sleeve has a mechanism to exert a force on the cork oriented toward the lower end of the stationary sleeve.

Abstract: The corkscrew with lever includes a spiral mounted rotating on a zone of a handle between an end segment and a maneuvering segment, and a telescoping arm having a first element mounted rotating on the end segment and a second element, having an upper end and a lower end, mounted sliding in the first element between an idle position and a second position. The lower edge of the lower end of said second element is provided to bear on the neck of a bottle. The end segment defines a circular cam having, as center, the second axis and able to act on the upper end of the second element, which is connected to the second axis using a return member. In a usage position of the corkscrew, its upper end is continuously kept in contact with the cam and its lower end extends continuously outside the first element.

Abstract: A system (1) for viewing a gemstone, the system (1) including a first light source (2) configured for selectably illuminating at least one of a plurality of features of the gemstone; an optical magnifying unit (10)configured for providing a magnified view of the plurality of the features of the gemstone in which at least one of the plurality of features of the gemstone is selectably illuminated by the first light source (2); and a viewing display unit (11) configured for displaying a representation of the magnified view.

Abstract: The seasoning mill includes a body, a cap closing the top of the body, a cup closing the bottom of the body and a drive shaft positioned inside the body. A first of the drive shaft is secured to a ball able to rotate inside the cup, the drive shaft having a device for agitating the seasoning. An agitating device includes a first blade to push the seasoning downwards in the direction of the cup when the shaft is rotated. The first blade is positioned near the first end of the drive shaft. A bottom end of the first blade has a shape cooperative with an upper edge of the cup, so as to unstick agglomerated seasoning residues from the upper edge of the cup.

Abstract: A method for removing oil from a physical object comprises the steps: i) bringing said physical object in contact with an oil removal composition, said oil removal composition comprising a) a surfactant having the general formula: R1-X—R2, wherein R1 is an open chain sugar alcohol, wherein X is one selected from NH, NCH3 and NCH2CH3, and wherein R2 is an aliphatic or aromatic group comprising at least 5 carbon atoms, and b) water, ii) leaving said oil removal composition in contact with said physical object for a period of time sufficient for most of said oil to be dispersed in said oil removal composition, High recovery of oil/bitumen from tar sands can be achieved. The composition is renewable, degradable and inexpensive. An extremely efficient de-greater is provided. The composition used in both bitumen recovery and degreasing is easily reusable and recycleable. The starting materials of the surfactant are renewable and inexpensive. The composition is non-toxic and biodegradable.

Abstract: A method of recovering crude oil from a subterranean hydrocarbon-containing formation, comprises the steps: i) injecting into said formation an enhanced oil recovery composition comprising a) a surfactant having the general formula: R1-X—R2, wherein R1 is an open chain sugar alcohol, wherein X is one selected from NH, NCH3 and NCH2CH3, and wherein R2 is an aliphatic or aromatic group comprising at least 5 carbon atoms, b) water, and ii) recovering the crude oil, typically from one or more production wells. One advantage is that the composition is natural product-based. It has superior emulsification, wetting and dispersion capabilities. The composition functions well under heat, pressure, high salinity and high water hardness. The starting materials of the surfactant are renewable and inexpensive. The surfactant is non-toxic and degradable.
