US Patent:

20040065375, Apr 8, 2004

Filed:

Oct 7, 2002

Appl. No.:

10/265491

Inventors:

John Snider - Nashville TN, US

International Classification:

F15D001/00

US Classification:

138/039000, 138/037000

Abstract:

Moving fluids are subjected to acceleration forces in turns, contractions, expansions and when flowing around bluff bodies. These forces can result in losses that are much larger than friction losses. For internal flow contractions, it is known that constant acceleration will eliminate pressure losses by balancing the forces that cause these accelerations with changes in static pressure. This disclosure teaches how to provide constant deceleration forces in expansions (diffusers) by maintaining a constant area to shear surface ratio, known as hydraulic diameter. Also taught, is how to design a turn vane array that has a hydraulic diameter equal to the upstream ducting diameter. Lastly, that these design techniques apply equally well to external flow regimes and a simple calculation demonstrates this method. Constant Acceleration Fluid Dynamics, results in ducting and bluff bodies that have no losses other than friction.

US Patent:

Filed:

Mar 16, 1983

Appl. No.:

6/474424

Inventors:

Frank H. Speckhart - Knoxville TN
John N. Snider - Knoxville TN

Assignee:

University of Tennessee Research Corporation - Knoxville TN

International Classification:

B23B 4516

US Classification:

173139

Abstract:

An impact force shaping head includes an elongated casing having an interior wall, an open end and a closed end and contains a liquid. A piston is slidingly mounted within the casing and extends longitudinally beyond the open end of the casing. The piston sealingly engages the interior wall of the casing to define a liquid-filled first chamber between the piston and the closed end of the casing. A reservoir contains liquid and a conduit connects the first chamber with the reservoir. A control valve controls the flow of liquid through the conduit. The control valve is operative in response to changes in the pressure of the liquid contained in the first chamber.

Appl. No.:

8/572967

Inventors:

John Michael Snider - Nashville TN

International Classification:

F02M 2900

US Classification:

12318814

Abstract:

Gas flow pressure losses through fuel charge and exhaust gas flow conduits for internal combustion engines are greatly reduced by turning vanes in conduit flow bends of greater than 9. degree. around an inside radius of less than twice the effective diameter of the conduit. Such turning vanes are preferably given leading edge bevels of about 20. degree. to 24. degree. and trailing edge bevels of 13. degree. to 17. degree. which are substantially centered about an arc radius through the angular center of the flow bend.

Filed:

Apr 27, 1989

Appl. No.:

7/343576

Inventors:

John M. Snider - Knoxville TN

International Classification:

A63B 21065

US Classification:

272119

Abstract:

The invention is a rigid frame weightlifting exercise device that is worn by the user during weight training. The device accepts and securely holds standardized weights to the upper body of the wearer. The device is attached to the body by three straps, two about the shoulders and one about the waist, in the same manner as a mountaineer's backpack. The device also includes a stand to ease donning and removal of the backpack.

Appl. No.:

16/386772

Inventors:

John Michael Snider - Clinton TN, US

International Classification:

A61B 17/00

A61H 99/00

Abstract:

A method for strength and conditioning of the voluntary muscle and its ligaments in the prostate gland. The method uses a device inserted into the urethra to both extend and offer the contracting muscle resistance enabling the exercise of an unopposed muscle. This method reverses the atrophy of this gland known as Benign Prostatic Hyperplasia (BPH) which every man will experience should they live into their nineties.
