    Abstract: Disclosed is an apparatus for water jet cutting including: a water source; a pump communicating with the water source, generating a high pressure water flow; a tank containing an abrasive material in suspension, including a fluid and abrasive particles dispersed homogeneously in the fluid; and a cutting head in fluid communication with the pump and the tank, the cutting head including a mixing chamber. The tank of the abrasive material in suspension is in communication with the cutting head by an abrasive inlet channel and the cutting head is configured to generate a vacuum pressure that draws the abrasive material in suspension through the abrasive inlet channel toward the mixing chamber to mix the abrasive material in suspension and the high pressure water and form a jet of water and abrasive. Also disclosed is a method for generating a water jet cut that can be implemented with the apparatus.

    Abstract: The use of abrasive entrainment waterjet technology to cut objects located at the bottom of a body of water. Abrasive is conducted to an abrasive waterjet cutting head under the control of an abrasive feed and metering system that monitors the differential pressure between the cutting head and reservoir of abrasive material and maintains the pressure at the abrasive reservoir greater than the pressure hydrostatic pressure at the cutting head.

    Abstract: A composition comprising a fluid, and a material dispersed in the fluid, the material made up of particles having a complex three dimensional surface area such as a sharp blade-like surface, the particles having an aspect ratio larger than 0.7 for promoting kinetic boundary layer mixing in a non-linear-viscosity zone. The composition may further include an additive dispersed in the fluid. The fluid may be a thermopolymer material. A method of extruding the fluid includes feeding the fluid into an extruder, feeding additives into the extruder, feeding a material into the extruder, passing the material through a mixing zone in the extruder to disperse the material within the fluid wherein the material migrates to a boundary layer of the fluid to promote kinetic mixing of the additives within the fluid, the kinetic mixing taking place in a non-linear viscosity zone.

    Abstract: A method for cleaning tooth surfaces with a powder and a powder mixture, preferably by powder blasting with a powder-jet device, said device mixing the powder or the powder mixture with air to form a powder/air mixture, wherein said powder and/or powder mixture is an alditol or contains such alditol. Preferably, mannitol and/or erythritol are used, because of their anti-cariogenic effect. Xylitol is also suitable for cleaning tooth surfaces, especially of less strongly mineralized tooth surfaces like dentine.
