Thermal cycling system

This invention provides a system for performing PCR, and real time PCR in particular with great speed and specificity. The system employs a heat block containing a liquid composition to rapidly transfer heat to and from reaction vessels. The system makes use of the reflective properties of the liquid metal to reflect signal from the PCR into the vessel and out the top. In this way, the signal can be measured by an optical assembly in real time without removing the vessels from the heat block.

Stimulating fluid production from unconsolidated formations

The present invention provides methods of stimulating fluid production from an unconsolidated formation penetrated by a wellbore while preventing the migration of formation sand with fluids produced from the formation. The methods basically comprise the steps of injecting a liquid composition into a portion of the formation surrounding the wellbore which converts into a gel-like substance and plugs the permeability of the injected portion of the formation, but allows the injected portion to remain flexible and resist breakdown due to pressure cycling therein, creating at least one fracture in the formation extending from the wellbore through the plugged portion of the formation into an unplugged portion thereof and depositing hardenable resin composition coated proppant in the fracture and causing the resin composition to harden and consolidate the proppant into a hard permeable mass.

Instrument having walls for applying a composition on eyelashes or eyebrows

An instrument for applying a liquid or semi-liquid composition on the eyelashes or the eyebrows, comprising a core together with applicator means designed to collect the composition and to apply it on the eyelashes or the eyebrows, the applicator means projecting from the core between respective bases and tips, wherein the applicator means are arranged to form at least one hollow itself defining at least one applicator volume shaped firstly to contain the composition and secondly to enable at least one eyelash or eyebrow hair to pass therethrough in order to be coated in composition, the applicator volume extending from the tip towards the core along a fraction only of the length of the applicator means, the applicator volume being defined by at least first and second substantially solid walls disposed facing each other, each of the first and second walls presenting a nature that is substantially two-dimensional.

High alcohol content foaming compositions with silicone-based surfactants

This invention relates to a “high lower alcohol content” (>40% v / v of a C1-4 alcohol) liquid composition able to be dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers. The liquid compositions comprise a C1-4 alcohol, (>40% v / v), a silicone-based surfactant of at least 0.001% by weight for foaming to prepare a foamable composition, 0-10% w / w of additional minor components added to obtain the desired performance (a foamable composition), and the balance being purified water. The compositions may include emulsifier-emollients and mosturizers, secondary surfactants, foam stabilizers, fragrances, antimicrobial agents, other type of medicinal ingredients, and the like ingredients or additives or combinations thereof commonly added to alcohol gels or foams, aerosol compositions or to toiletries, cosmetics, pharmaceuticals and the like.
