Abstract: A process comprising: i) providing a body of metal ore, ii) contacting the body of metal ore with a microbial lixiviant comprising one or more populations of microorganisms, iii) measuring at least one parameter indicative of function of the one or more populations of microorganisms, and iv) adjusting one or more process variables in response to the measured parameter.

Abstract: The present application provides a process comprising: i) providing a body of metal ore, ii) contacting the body of metal ore with a microbial lixiviant comprising one or more populations of microorganisms, iii) measuring at least one parameter indicative of function of the one or more populations of microorganisms, and iv) adjusting one or more process variables in response to the measured parameter.

Abstract: The present invention comprises a generally rectangular base with two longitudinal containment lips and two semi-arcuate lips on the front and rear for the containment and display of motorcycles or similar vehicles. The apparatus is uniquely suited to hold and display motorcycles or similar vehicles in an aesthetically pleasing manner while also containing and fluid leaks or spillage that may occur during the storage or display. A pair of adjustable stands holding the vehicle. Each stand can be selectively raised and fixed in a vertical position and adjusted to hold the vehicle. The stands can be lowered to the surface when not in use or removed.

Abstract: A candle topper fits onto containerized candles, such as scented candles within a cylindrical apothecary jar, not only serving to enhance efficient combustion and add a decorative finish thereto, but also directing exhaust gases as a convective motive force to spin a fan. Thereby, hanging ornaments enhance the entertaining value of the candle topper.

Abstract: Vane actuating apparatus for adjusting the angle of incidence of a set of variable angle vanes in a gas turbine engine comprises a plurality of vane actuator levers attached at one end to a respective vane and at the other end to an actuation arrangement for moving the vanes in unison. Each lever has an interlocking connection arrangement for pivotally connecting the lever with respect to its respective vane in such a way that the lever is capable of being attached and detached from the vane at a first angular position, and retained in interlocking engagement for pivotal movement at a second angular position or range of positions.

Abstract: Disclosed are wax based inks for phase change/hot melt inkjet printing or thermal transfer printing applications. Also disclosed are waxes useful for toners for use in electrostatographic printing applications. Both materials are prepared using a wax having a narrow melting range. The narrow melting range of the wax reduces energy requirements in printing applications. The use of the waxes also promotes release for high speed printing and especially promotes fast drying in wax based ink applications.

Abstract: A yarn unwinding device is disclosed that consist of a base having a central raised portion there that has an upstanding central rod embedded therein. A hollow crochet spindle is rotatably received over the upstanding rod. The crochet needle has a pointed top and has a circular flange located at the bottom. In addition, there is a wider circular washer received over the needle and rests on the bottom flange. A skein of wound yarn is received over the top of the needle and rests on the circular washer at the bottom of the needle. The yarn is withdrawn laterally from the skein with only a limited resistance while unwinding during the process of knitting, embroidering or crocheting.

Abstract: The invention is a rubber or plastic mat with four sidewalls for collecting the grease drippings from a conventional barbecue grill. The mat is placed on the ground and the grill is simply rolled onto the mat. Specially shaped grease barriers allow the wheels of the grill to be rolled over them to place the grill over the center of the mat.
