Patent number: 6158293Abstract: Apparatus for determining flowability of a powder by sensing powder avalanching includes a sample drum having a generally cylindrical sample chamber for holding a powder sample, a support frame including a drum shaft for supporting the sample drum for rotation, a drive motor and a drive mechanism coupled between the drive motor and the drum shaft such that the drum rotates when the drive motor is energized. The apparatus further includes an avalanche sensor for sensing avalanching of the powder sample within the sample chamber as the sample drum rotates. The avalanche sensor may be implemented as a backlash sensor for sensing intermittent reverse angular displacement of the sample drum caused by avalanching of the powder sample. A torque loading sensor may also be used to sense avalanching of the powder sample. A controlled gas may be circulated through the sample chamber by a gas conditioning system. The gas in the sample chamber can be measured and/or controlled.Type: GrantFiled: March 17, 1999Date of Patent: December 12, 2000Assignee: TSI IncorporatedInventor: Trent A. Poole

Patent number: 6158431Abstract: A handheld therapeutic material delivery system includes a droplet dispersion chamber, a droplet generating assembly for generating droplets of a fluid containing the therapeutic material and for supplying the droplets to the dispersion chamber, and a gas conditioning assembly for supplying heated gas to the dispersion chamber to form a heated transport gas stream. The droplets are dispersed in the heated transport gas stream in the dispersion chamber to provide an aerosol stream containing the droplets. The aerosol stream is supplied to the patient in response to a negative pressure applied by the patient. The delivery system may include a droplet inspection assembly for determining a characteristic of the aerosol stream and a feedback unit responsive to the determined characteristic of the aerosol stream for controlling one or both of the droplet generating assembly and the gas conditioning assembly.Type: GrantFiled: February 13, 1998Date of Patent: December 12, 2000Assignee: TSI IncorporatedInventor: Trent A.

Patent number: 5779093Abstract: A paint can guard is mounted on a sealing rim of a paint can. The paint can guard includes an annular rim guard for covering the sealing rim of the paint can, an annular brush wiper having an inner surface and an outer surface, and a plurality of struts coupled between the rim guard and the wiper for supporting the wiper in spaced relation to the rim guard. A substantially annular passage is defined between the outer surface of the wiper and the rim guard. Paint from a brush wiped on the wiper may flow on the inner surface of the wiper into the paint can. The brush can also be wiped on the upper or lower edge of the wiper. Paint that drips or spills outwardly of the wiper may flow through the passage between the outer surface of the wiper and the rim guard into the paint can, thus avoiding spillage.Type: GrantFiled: September 20, 1996Date of Patent: July 14, 1998Inventors: Trent A.

Patent number: 5522555Abstract: A powder dispersion system, including a powder disperser and a control unit, supplies a controlled particle stream to a particle sizing system, instrument, or other processing device. The powder disperser includes a dynamic shear dispersion assembly and may include a fluidization assembly. An impact surface for deagglomeration of particles is located within a rapid acceleration chamber of the dynamic shear dispersion assembly. The particles are accelerated from the impact surface through an annular nozzle. A feedback loop dynamically controls the dynamic shear force applied to the aerosol transport gas, which in turn places reaction forces upon the particles, within the annular nozzle. The fluidization assembly includes a primary chamber for holding a powder sample and a secondary chamber for entraining particles of the powder sample in a transport gas stream. A pulsed gas jet directed into the primary chamber disperses particles of the powder sample into the secondary chamber.Type: GrantFiled: March 1, 1994Date of Patent: June 4, 1996Assignee: Amherst Process Instruments, Inc.Inventor: Trent A.
