Abstract: Systems and methods for separation of oleaginous fluids, aqueous fluids, and solids from drilling or other oilfield emulsions by solvent extraction. A method for separation of oilfield emulsions comprising: providing an oilfield emulsion prepared for use in a wellbore and/or recovered from a wellbore; mixing the oilfield emulsion with at least a solvent to form at least a mixture; and separating the mixture to at least partially recover an oleaginous phase of the oilfield emulsion.

Abstract: An insert for disposal in a beverage container includes a chamber for containing a volume of fluid, e.g. a flavor component, an inlet valve to permit gas to enter the chamber, an outlet valve to permit fluid to exit the chamber. In a preferred form, the insert is connected to suspend from a lid or crown closure of a beverage container.

Abstract: A valve assembly including a main body (13,24) with a cavity (25) having an aperture (35a) formed through the main body and channels (26) formed radially in the cavity wall. A seal member (18) is shaped to fit within the cavity such that when the seal member moves away from the aperture flow is permitted in the channel toward and through the aperture. The valve is for incorporation with a tap device, particularly for use with a “mini-keg” of beverage.

Abstract: A method for integrating a batch cement process with a cuttings reinjection process, the method comprising: equipping a batch cement skid with a particle classifier and a grinding pump, such that the batch cement skid sequentially implements the cuttings reinjection process and the batch cement process is disclosed. An apparatus for performing a batch cement process and a cuttings reinjection process, the apparatus comprising: a first tank and a second tank, a particle classifier having a coarse effluent stream feeding into the first tank and a fine effluent stream feeding into the second tank, and a grinding pump in fluid communication with the first tank and the particle classifier is also disclosed.

Abstract: A disposable product dispenser for dispensing product (60) into a liquid prior to consumption by a user comprises a quantity of product (60) sufficient for a drink or dose, and a holder (1) for the product. The holder (51) is arranged to permit a user to release the product in a controlled manner and to mix the product with a liquid. The dispenser may be for dispensing a liquid or solid and has particular application in the beverage industry permitting customers to mix their own drinks.

Abstract: An illuminated artificial tree having a display position and a folded position is constructed of an odd number of upright wire mesh panels hingedly attached at their vertical inner edges, the panels including a first end panel, a second end panel and a plurality of intermediate panels between the first and second end panels. A string of decorative lights are attached in a plurality of spaced, reversed loops, the string extending from adjacent the lower edge of the first panel around the intermediate panels to the second panel, then upwardly along the outer edge of the second panel, and then back around the outer edges of the intermediate panels to the first panel, thereby permitting folding of the tree without removal of the light string.

Abstract: An apparatus adapted for analyzing exhaust emissions by using a small fraction of a continuously-extracted exhaust sample combined with a pollutant-free diluent through a system of critical flow orifices at a predetermined and precisely controlled flow ratio. A small quantity of gas is extracted from the diluted exhaust gas available which is diluted with the contaminant-free air or nitrogen to produce a mixture having a dew point below ambient air temperature and satisfying the flow requirements of the analysis system. The diluted sample may then be analyzed to obtain the total mass of pollutants through identification of the instantaneous exhaust concentration rate and the exhaust mass flow rate or through identification of the concentration of pollutants collected in a sample bag and the total exhaust volume.
