Abstract: A liquid dispensing hairbrush apparatus for evenly and easily distributing liquid hair product through hair while brushing includes a brush handle having a handle sidewall, a handle top end, and an open handle bottom end defining a handle reservoir. A cap is selectively engageable with the handle bottom end. A brush head is coupled to the handle top end. A head front side has a plurality of dispense apertures extending through to the head inside. A plurality of bristles is coupled to the head front side. A bladder is coupled to the brush head within the head inside and is in fluid communication with the plurality of dispense apertures. A pump is coupled within the brush and has an actuator button extending through the handle sidewall to pump liquid from the handle reservoir to the bladder.

Abstract: A process of stimulating hydrocarbon recovery is described and claimed. This process includes introducing a gas, a liquified gas or a vaporized liquified gas, into an underground formation containing hydrocarbons such as crude oil and gas, permitting said gas to be absorbed by said hydrocarbons, and withdrawing said hydrocarbons containing the gas therein, wherein a pill of Hydrocarbon Recovery Fluid comprising surface functionalized nanoparticles is inserted into the underground formation containing hydrocarbons before, during or after the introduction of the gas, liquified gas or a vaporized liquified gas.

Abstract: A system and a method for detecting a failure of a heat exchanger provided on an engine of an aircraft. An out-of-range fuel temperature downstream of an outlet of the heat exchanger is detected. A health of a fuel tank temperature signal indicative of a temperature of at least one fuel tank of the aircraft is monitored. A main oil temperature signal indicative of a temperature of oil in the engine is received. The failure is detected based on the main oil temperature and on the health of the fuel tank temperature signal.

Abstract: Stable, gas-filled bubbles on the surface of proppant particles are formed by placing proppant in selected organic solvent having a much greater solubility of a selected gas compared to water, pressurizing the solvent with the selected gas, e.g., nitrogen, at pressures equal of greater than the operating pressure for a set time period to achieve saturation, and then replacing the solvent with water before reducing the pressure back to operating pressure level to create a local supersaturation near the solvent-solid interface, which will result in gas-filled bubble formation on the surface of proppant particles. The pressurized mixture of bubble surrounded proppant particles and water can then be combined with a respective fracturing fluid, e.g., slick water or carbon dioxide and/or nitrogen foam or an emulsion, which can be used in oil or gas producing wells to improve efficiency of hydraulic fracturing thereof.

Abstract: The present application relates to a traffic calming surface, the upper surface of which has a continuous, substantially sinusoidal, profile which extends along the intended direction of travel. An advantage of traffic calming surfaces according to embodiments of the present invention is that they have been shown to generate significant interior noise and vibration which will act as a warning to the driver that he should reduce his speed. Trials have also shown that exterior noise disturbance, caused by vehicles traversing the surface, is substantially reduced as compared to the exterior noise arising from conventional rumble strip designs.
