FIELD: treatment and cleaning of facing surfaces of buildings, structures and various objects in construction and other fields of national economy. SUBSTANCE: the method consists in the fact that at a continuous feed of compressed air to the transportation flow solid particles of the working medium continuously form a suspension. The suspension is fed to the working member in the form of a nozzle in which it is influenced by an auxiliary flow of hot gaseous working medium in the form of a supersonic stream. The hot gaseous working medium, simultaneously with transfer of kinetic energy to suspended solid articles of the working medium, warms up and expands air in the suspension. Due to the excess of temperature of gaseous working medium relative to the suspension, the rate of flow and speed in the nozzle increases by hundreds of times and initiate the supersonic speed of outflow acting on the building stone facing. The device for production of hot gaseous working medium in the form of a supersonic stream has a body accommodating a combustion chamber, prechamber and concentrically positioned main and auxiliary air flow swirlers, injector and homogenizer of fuel-air mixture. The body is positioned in a housing enveloping it with formation of a cooling cavity. Installed on the outlet end of the body is a replaceable nozzle formed by a contraction and diffuser. The housing cooling cavity is connected through the swirler to the compressed air source and communicates with the combustion chamber. Ignition of liquid fuel is provided by an electric spark discharge initiated by the glow plug electrodes. EFFECT: enhanced rate of surface treatment and simultaneous reduction of consumption of working medium and provision of adjustment within a wide range of the rate of surface treatment and consumption of working medium. 4 cl, 3 dwg 63 961с ПЧ ГЭ (19) РОССИЙСКОЕ АГЕНТСТВО ПО ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ ВИ” 2 158 197 Сл (51) МПК?

An ultrasonically actuated rod vibrates within the cannula engaging a nozzle, disrupting the fluid jet into droplets, permitting tuning of the jet to the resonant frequencies and impact pressures necessary to dissociate the target tissue. A suction recovery system may be separated or integrally formed with the fluid jet cannula, and is linked by a closed tubing system appropriate for sterilization and subsequent delivery of the harvested cells/tissues with or without growth factor or matrix addition for human re-implantation or for in vitro expansion for later re-implantation.

Abrasive liquid jet cutting

ABSTRACT OF THE DISCLOSURE Abrasive liquid jet cutting is provided by disposing abrasive particles in positionally supported form, as on a carrier, such as sandpaper, between the liquid jet nozzle and the workpiece. The particles are intercepted by the liquid jet and driven into the workpiece which may be ferrous or nonferrous metal. The particles may be bonded to a paper-like backing, incoporated in a binder, such as a viscous paste, or formed into a rod-like structure. Variable feed of the workpiece or the abrasive carrier can be used to provide optimized or selective abrasive cutting.
