Method And Apparatus For Counting Particles Of Particulate Material
US Patent:
4157468, Jun 5, 1979
Filed:
Jun 10, 1977
Appl. No.:
5/805413
Inventors:
Michael P. Primiano - Lake Oswego OR
International Classification:
G01D 2104
US Classification:
250223R
Abstract:
Infrared or visible light radiation is arranged to traverse substantially the entire cross sectional area of a passageway as a wide, flat beam having a thickness not substantially exceeding the minimum thickness of particles to be counted and a width substantially greater than the thickness, and is detected as a field of radiation of substantially constant intensity. When a particle falls by gravity through any portion of the field, the detected change in intensity functions to activate an electronic counter which provides a direct digital readout of the number of particles passing through the field in a given period of time, distance, or area.
Water Jet Teeth Cleaner
US Patent:
D340763, Oct 17, 1989
Filed:
Oct 5, 1987
Appl. No.:
7/104307
Inventors:

US Classification:
D24 15
Water Jet Teeth Flossing Apparatus
US Patent:
5027798, Jul 2, 1991
Filed:
Aug 10, 1988
Appl. No.:
7/231495
Inventors:
Michael J. Primiano - Lake Oswego OR
International Classification:
A61H 900
US Classification:
128 66
Abstract:
A dental water jet flossing apparatus comprises an elongated, flexible tubing attached at one of its ends directly to a household water supply, preferably at a point where water temperature can be controlled, as at the water outlet pipe mounting a shower head. The opposite end of the tubing is connected to a hand-held unit that is configured to releasably mount a dental water jet nozzle. A water flow control valve is included in the hand unit and configured to engage the flexible tubing and selectively constrict the latter to various desired degrees to selectively control the amount and rate of water delivered through the tubing and hence expelled from the nozzle. A syphon cup containing mouthwash or the like may be provided in-line to meter desired fluids into the water being delivered out of the nozzle and into the user's mouth.
