Provided is an aerosol method, and accompanying apparatus, for preparing powdered products of a variety of materials involving the use of an ultrasonic aerosol generator (106) including a plurality of ultrasonic transducers (120) underlying and ultrasonically energizing a reservoir of liquid feed (102) which forms droplets of the aerosol. Carrier gas (104) is delivered to different portions of the reservoir by a plurality of gas delivery ports (136) delivering gas from a gas delivery system. The aerosol is pyrolyzed to form particles, which are then cooled and collected. The invention also provides powders made by the method and devices made using the powders.

A method for monitoring a ball used for an athletic activity includes detecting movement of the ball at a first time, using a sensor module coupled to the ball, determining that the movement of the ball corresponds to a predetermined activation movement, entering an active state of the sensor module in response to the determination that the movement of the ball corresponds to the predetermined activation movement, and detecting movement of the ball at a second time, using the sensor module in the active state.

A process for producing nanoscale powders, and the powders so produced. The process comprises mixing an emulsion comprising all of the elements of the desired powder composition and a combustible fuel, and then combusting that emulsion to produce a powder. Powders with a median particle size of less than 50 nm have been made by this process. The process is suitable for the production of many types of powders, including particles and nanowhiskers of simple, doped, and polymetallic powders.

Issues of cost and product quality have caused papermakers to place increased attention on the use of mineral additives, which are the subject of this review article. Technologists responsible for the production of paper can choose from a broad range of natural and synthetic mineral products, each of which has different characteristic shapes, size distributions, and surface chemical behavior. This article considers methods of characterization, and then discusses the distinguishing features of widely available filler products. The mechanisms by which fillers affect different paper properties is reviewed, as well as procedures for handling fillers in the paper mill and retaining them in the paper. Optical properties of paper and strategies to maintain paper strength at higher filler levels are considered. The goal of this review is to provide background both for engineers working to make their paper products more competitive and for researchers aiming to achieve effects beyond the current state of the art.

Process and composition for the production of cemented metal carbides

Process for making metal/metal oxide compositions

Disclosed herein are flatted water-reducible coating compositions of the varnish, paint or enamel types, which compositions comprise a water-miscible film forming resin, water as the predominant solvent and a particulate finely-divided silica flatting agent. The method of the invention involves the initial production of a mill paste formulation containing the film forming resin followed by a let-down step employing water as the predominant solvent. The silica flatting agent is introduced into the composition as an aqueous dispersion thereof during or after said let-down step.
