Filed:

Jun 16, 2003

Appl. No.:

10/462255

Inventors:

Larry Ray Potts - Portland OR, US
Richard Allen Potts - Seattle WA, US

International Classification:

B65B031/04

US Classification:

141 65, 141329

Abstract:

A drum drilling apparatus that is capable of powered operation with standard issue emergency crew SCBA equipment. The drum drill resides moveably on a platform that is adaptable to be positioned about any sized container regardless of any irregularities in the ground surface. It provides several safety related features such as the capability for remote operation, static electric grounding, and explosion shielding. It has sampling/purge capabilities and adapts for use with LPG cylinders. It is lightweight and capable of operation by one person. It provides the least intrusive method of drum depressurizing.

Inventors:

Richard Allen Potts - Burien WA, US
Larry Ray Potts - Portland OR, US

International Classification:

A61B 5/02

US Classification:

33290, 33DIG 21, 600485

Abstract:

A medical laser vertical alignment system that has a precise locating strip affixed perpendicularly to a static pressure scale and that vertically and horizontally aligns the center of rotation of a reusable detachable laser aligning device with the zero reference point of the scale. The laser beam light is adjustable to coincide with the indicated horizontal position of a set of two bubble leveling vials. It has a quick release and alignment clamping arrangement that affixes the laser aligning device to the locating strip. The leveling device can be rotated 180 degrees and the leveling vials are located at opposing sides and ends of the device for clear visibility and redundancy. There is a timer circuit in the device that shuts the laser off after a predetermined time.

Inventors:

Richard Allen Potts - Ferndale WA, US
Larry Ray Potts - Portland OR, US

International Classification:

A61N 5/06

US Classification:

607 90

Abstract:

A microprocessor controlled medical laser device that has a precise laser beam alignment system indicated by a series of sequentially color changing LEDS. The power management system adjusts the LED'S power input so as maximize battery life, increasing it by up to six times. It's alignment is enabled by a triaxial accelerometer that may be accurately calibrated horizontally or to a plethora of angles relative to the horizontal axis. It is shock resistant and times out to turn the laser off after a predetermined time.
