Abstract: The present disclosure relates to a method of compacting an ash deposited in a particulate filter for a vehicle exhaust gas system, the method includes the steps of: a) providing a low-temperature melting salt to the particulate filter, thereby forming a mixture of the ash and the low-temperature melting salt: and b) heating the particulate filter to a compaction temperature, thereby compacting the mixture of the ash and the low-temperature melting salt. The disclosure further relates to engine oils, dosage products, engine systems and vehicles for implementing such a method.

Abstract: This disclosure describes a filtration system and method for removing soap from diesel fuel. The removal involves passing fuel through the filtration system. By removing soap, injector sticking and plugging can be reduced and for fuel already contaminated with soap, lubricity and/or corrosion inhibition functionality resulting from the conversion of carboxylic acid additives can be restored to metal carboxylates.

Abstract: A lubricant and method for cleaning a drive chain of an apparatus, such as a bicycle or motorcycle. The lubricant of the present invention comprises a water miscible lubricating material, that will tend to stay on the chain during dry, and typical wet condition encountered on a bicycle, yet enable the removal with a direct blast from a solvent. The method for cleaning the drive chain comprises providing the solvent, such as any polar liquid, such as water. A continuous supply of clean solvent may be available from a source, such as a common garden hose or bottle. Forceful spraying onto the first surface in the direction of the arrows removes lubricant that is contaminated with dirt and/or sand from the first surface of the chain to form a layer of solvent and contaminated lubricant on the ground upon which the apparatus is supported or rides.

Abstract: A composition of matter resistant to foaming comprising a hydrocarbon oil and an acrylate copolymer dispersed in the said hydrocarbon oil, which acrylated copolymer contains at last one polymerised fluorinated (meth)acrylate monomer wherein not more than three neighbouring carbon atoms in the said fluorinated (meth)acrylate monomer carry one or more fluorine substituents.

Abstract: A nebulization system, which creates a uniform fog of tiny suspended liquid droplets, to lubricate the surfaces of MEMS devices. These droplets fall over the edge of a baffle and are then mixed with an umbrella-like sheet of N2 turbulation gas to generate a uniform cloud of droplets that fill a passivation chamber. The MEMS device is then positioned in this uniform cloud of lubricant droplets for a specified amount of time, thereby uniformly lubricating all the surfaces of the device. The system uses a laser monitoring approach to control the uniformity of the lubricant cloud by providing feedback to the system to control the flow of gases. The system also equalizes the pressure around the sample device seal to prevent gases from entering or exiting the chamber and thereby influencing the environment inside the chamber.

Abstract: A method of dispensing a lubricant into a micromechanical device package and a micromechanical device package containing the lubricant. The method comprises the steps of mixing (102) the lubricant, typically a perfluoroalkanoic acid such as perfluorodecanoic acid with a suitable solvent, typically an ether solvent such as tetrahydrofuran or tert-butyl methyl ether. The mixture is allowed to equilibriate (104) before being filtered (106) to remove solid particles. The filtered solution is applied (108) to a surface that will be on the interior of the package, typically the ceramic substrate. The deposited mixture is then cured (110) to remove most, if not all, of the solvent, and the package is sealed (112).
