  • Enablement of selection of gas/dry ice ratios within an allowable range, and dynamic maintenance of the ratio in a blasting stream
    Patent number: 6695679
    Abstract: Apparatus and method to establish permissible ranges of the gas/dry ice ratio in a dry ice blasting stream. Logic and circuitry determine whether a proposed ratio is permissible. If it is, it enables the process to start. If it is not, it forbids operation of the process.

  • Dry ice blasting gun with adjustable handle
    Patent number: 6447377
    Abstract: A hand-held blasting gun for use in dry ice blasting for cleaning purposes. A handle and a nozzle mount are pivotally joined so a nozzle on the nozzle mount can be adjustably directed relative to the handle. A flexible hose is fitted in the gun, extending from the end of the handle to the nozzle so as to send without kinking.

  • Generation of an airstream with subliminable solid particles
    Patent number: 6346035
    Abstract: Apparatus to prepare an airstream laden with particles of solid dry ice. A rotor has passages which sequentially pass a source of particles and a source of air under pressure to prepare the airstream and send it to a nozzle. The rotor is held between pads whose force against the rotor is a function of air supply pressure. The speed of the rotor and of the particle feed are controllable, and the air feed persists after particle feed has stopped for a period of time sufficient to clear particles from the rotor.
