Dental Implant Modification

Kisielewski, R.W., Hastings, C.K., McCarthy, G.R. (FDA)
Filed 19 Apr 95
Serial No. 08/424,786.

    Description of the Invention: Implanted dental prostheses are 
subjected to large forces acting in different directions within 
severely-limited space. Screw and/or nut connections, while useful in 
the construction of these prostheses, are subject to relative rotations 
which can lead to undesirable loosening of the implant at inopportune 
times. The present invention greatly inhibits the undesirable loosening 
of the dental prosthesis by providing for a linear, axial transmission 
of forces from the prosthesis to a tubular spacer and an implanted base 
by the retaining nut. This invention has the additional advantage of 
permitting relatively easy retrofitting of existing dental prostheses 
which were prone to failure due to loosening when the retaining nut or 
screw turned under the forces normally found in previously available 
prostheses.
    Potential Areas of Application: Applicable to improvement of dental 
prostheses used world-wide; design adaptable to other prosthetic 
securing applications.
    Main Advantages of Invention: Inexpensive to apply to existing 
prostheses; much improved functional design. [portfolio: Dental

Drycleaning Secondary Vapor Isolation and Removal System

Earnest, G.S., Froehlich, P.A. (NIOSH)
Filed 27 Oct 94
Serial No. 08/329,920.

    Description of the Invention: A system which reduces environmental 
emissions and operator exposure to solvent vapors associated with dry 
cleaning machines. Dry cleaning solvents such as perchloroethylene are 
known to cause liver and kidney damage and to contribute to ozone 
depletion. Due to the operational nature of dry cleaning machines, 
which involves continuous loading and unloading, operators are exposed 
to solvent vapors which are emitted each time the machines are opened. 
The invention involves a ventilation system which isolates, contains 
and removes residual solvent vapors before a dry cleaning machine 
chamber is opened.
    Potential Areas of Application: Closed circuit dry cleaning 
machines; exhausting dry cleaning machines; single and multiple bath 
processing machines.
    Main Advantages of Invention: Reduce worker exposure to hazardous 
solvent vapors; reduce emission of hazardous vapors into the 
environment; can be retrofitted onto existing dry cleaning machines.
    Stage of Development: Conceptual only. [portfolio: Devices/

An Integrating Sphere Which Delivers a Homogeneous Beam of Laser Light 
for Use in Photodynamic Therapy

Smith, P.D., Cole, J., Harrington, F., Bernstein, E. (NCRR)
Filed 24 May 94
Serial No. 08/248,918.

    Description of the Invention: An irradiation attachment for an 
optical fiber which provides an output of light that has a highly 
uniform intensity. Frequently, optical fibers are used in illumination 
delivery systems. However, in general the output from optical fibers is 
irregular due to a number of factors which include: imprecise 
introduction of light into the fiber; imperfect cleaving or polishing 
of the fiber output face; and distortions introduced by handling the 
fiber. The inventive device simply attaches to the end of a delivery 
optical fiber and overcomes the irregularities and produces a uniform 
level of illumination. The inventive device permits uniform irradiation 
of irregularly shaped objects.
    Potential Areas of Application: Photodynamic therapy; treatment of 
psoriasis; uniform illumination of flat and raised surfaces.
    Main Advantages of Invention: Simple attachment to optical delivery 
fibers; hand held; uniform illumination of flat and raised surfaces.
    Stage of Development: Prototype built and tested on laboratory 
animals. [portfolio: Devices/Instrumentation--Therapeutics,

Ventilated Casting Grinding Workstation With Turntable

Gressel, M.G. (CDC)
Filed 20 May 94
Serial No. 08/247,181.

    Description of the Invention: A new ventilated workstation which 
reduces worker exposure to hazardous particulate materials has been 
invented. In conventional foundry casting operations, castings are 
cleaned by hand using pneumatic chipping and grinding tools. The 
grinding and chipping of sand burnt into the castings results in a 
discharge of respirable silica particles. The workstation of the 
present invention is equipped with a rotatable workpiece holder which 
allows all surfaces of the workpiece to be positioned so that particles 
discharged by grinding or machining are directed toward a ventilation 
area at which the discharged particles are removed.
    Potential Areas of Application: Cleaning foundry castings; 
machining workpieces.
    Main Advantages of Invention: Reduces worker exposure to hazardous 
particulate materials; easy to retrofit to existing ventilated 
workstations.
    Stage of Development: Prototype built, tested, and evaluated.

Exhaust Ventilation Control System for Casting Cleaning in a Foundry,''

Magnetic Resonance Monitor

(Bowman, J.D., Engel, D.P. (NIOSH)
Filed 29 Apr 94
Serial No. 08/235,833.

    This invention relates to measurement of static and extremely low 
frequency magnetic fields. Further, it permits measurement of 
environmental magnetic fields which are in magnetic resonance with 
magnetic moments in a biological organism, particularly the human body. 
This invention overcomes deficiencies in current systems, such as: only 
measuring oscillating magnetic fields, measuring static and oscillating 
fields with Hall-effect or flux-gate probes, and measuring static and 
oscillating fields and all their characteristics without taking into 
consideration chemical and biological effects. [portfolio: Devices/
