Appl. No.:

12/551416

Inventors:

Boaz Barry Groman - Boca Raton FL, US

International Classification:

B24C 7/00

US Classification:

451 38, 451 90

Abstract:

A micro-abrasive blasting device comprises a mixing chamber, a delivery conduit extending from external the mixing chamber to the mixing chamber and a discharge conduit extending from the mixing chamber. Abrasive material may selectively be sealed in the chamber by positioning the discharge conduit to abut the inlet port. The chamber may be spherical to deliver consistent powder perturbation at all mixing chamber orientations. Methods of using the device are disclosed. Methods of making the device by blow molding are disclosed.

Appl. No.:

13/083532

Inventors:

Boaz Barry Groman - Boca Raton FL, US

International Classification:

B24B 3/00

US Classification:

451 90, 451 99

Abstract:

A micro-abrasive blasting device and method for perturbation control may use a plurality of delivery conduits of various lengths and/or apertures, or a single moveable delivery conduit. The user is able to individually open and close bypass conduit pinch valve(s) external to micro-abrasive blasting device to affect the perturbation intensity internal to the mixing chamber. By selectively opening and closing flow through delivery conduits it is possible to provide a more consistent perturbation rate and select the perturbation intensity internal to mixing chamber.

Appl. No.:

12/573891

Inventors:

Boaz Barry Groman - Boca Raton FL, US

International Classification:

B24C 5/02

US Classification:

451 38, 451 90

Abstract:

A tip component of a powder blasting device comprising a powder delivery portion and a detritus evacuation portion (evacuator tube) which may be formed as a single unit. The powder delivery portion comprises a mixing chamber, an inlet port and an outlet port. A gas delivery conduit extends to the inlet port. A discharge conduit extends through the outlet port and is movable to selectively seal powder within the mixing chamber. The detritus evacuation portion comprises an elongate tube. An adapter component comprises a pressurized-air delivery portion and a vacuum portion, formed as a single unit. A pressurized air source provides pressurized air to a pressurized-air delivery portion of the adapter component; and a vacuum source provides vacuum to a vacuum portion of the adapter component. An evacuator handpiece may be disposed between the vacuum portion of the adapter component and the evacuator tube of the tip component.

International Classification:

A61C 3/02
A61C 5/14

US Classification:

433088000, 433136000

Abstract:

The present invention is a device for capturing abrasive particles expelled from air-abrasive apparatus and permitting their facile removal without the aid of a vacuum source, while facilitating an unobstructed view of the working area during use. One embodiment disclosed is a capture and removal device () of abrasive material () expelled by a gas abrasive dental apparatus () by generating a water curtain () from a water steam () delivered substantially tangential to concave surface () of a curved sheet (). A method is disclosed for using water curtain () generated by capture and removal device () to capture and remove abrasive material () from the vicinity of an air-abrasive procedure. Certain other embodiments of the device can be used for non-dental applications.

Inventors:

Boaz Barry Groman - Boca Raton FL, US

International Classification:

A61C 3/02

US Classification:

433 88

Abstract:

The present invention is a micro-abrasive blasting device () constructed from a disposable pipette structure () comprising a delivery conduit () extending from a delivery conduit inlet () through a tapered section () to form a delivery conduit outlet () and a inlet port (); contiguous pipette structure () expands from inlet port () to form a hollow bulb mixing chamber () and then narrows to form a discharge port () section; a discharge conduit () is in fluid communications with discharge port () and extends from a discharge conduit inlet () internal to mixing chamber () to a discharge conduit outlet () external to mixing chamber (); a particulate matter () is disposed within mixing chamber wall (); discharge conduit inlet () abuts inlet port () preventing particulate matter () from exiting mixing chamber . A separation gap () between the delivery conduit outlet () and discharge conduit inlet () is created as discharge conduit () is displaced so discharge conduit inlet () no longer abuts inlet port (); As pressurized-gas is supplied to micro-abrasive blasting device () through the delivery conduit inlet (), the pressurized-gas flows through the delivery conduit () and out of the inlet port (), into mixing chamber (). As flow is initiated, particulate matter () instantaneously mixes with the gas-steam within hollow resilient bulb mixing chamber () and the powder-gas mixture flows through discharge conduit () to strike target surface ().
