ABSTRACT

Fluid flow regulator for intercalation in conduits through which flows a medium to be

regulated, having a housing with interengaging inner and outer members, the inner

member being in form of an axial, profiled core portion, at least one housing member

having intermittent flow passages therein, together with at least one seating surface

for an elastically deformable sealing member which constitutes flow throttling means.

A bypass valve my be provided in an axial inlet passageway of the regulator. The

sealing member is preferably annular but may have a different profile, such as

rectangular, lip shaped or other. The flow passages are radially or axially disposed

for respective axial or radial operation of the sealing member as a result of a pressure

difference of the medium being regulated between the inlet and outlet sides.

FUNCTIONAL DESCRIPTION

As shown in Fig. 1 the Liquid Medium enters the Flow Regulator at [p1] in the direction the

arrow indicates and leaves the Regulator on the Outlet side [p2].

The Liquid Medium is in almost all applications water.

Fig. 2 shows in Position 1 the O-Ring [d] in expanded and resting Position due to no Medium

Flow and consequently no presents of pressure. This situation changes in Position 2 when

Pressure and Medium Flow increase. Simultaneously the O-Ring is drawn against the

Protuberances [f] and reduces the through let area [F2]

The Protuberances [f] of the Profiled Core [c] are designed in a manner that in Position 2

and later at high pressure in Position 3 the nominal flow value this core was designed for

remains constant. In other words the O-Ring [d] penetrates the Profiled Core [c]

continuously deeper with increasing pressure narrowing the Through Let areas [F2] and (F3].

The curve / diagram below shows 3 different Regulators which have a constant flow under

increasing and decreasing pressure conditions.

The question is: "Why does the O-Ring perform in this way?" The answer is: The differential

pressure which occurs between [p1] and [p2] and the narrowing pass way between

the inner diameter of the O-Ring and the Profiled Core increase the speed of the medium to

a very high extend which leads to a Venturi or Vacuum like effect which forces the O-Ring

towards the center.

The design of this Patent appears to be simple - however, it was never discovered before,

until I stumbled over it during needle valve testing in 1970. This makes this Regulator a

remarkable discovery.

After almost 40 years this regulator is still sold exactly the way I designed it and adds

up to many millions distributed all over the world. When this regulator came on the market

it revolutionized industries like Instantaneous Water Heaters, Faucets, Shower Heads,

Filters, Aerators, Solenoid Valves, Appliances and many other industrial applications.

Take a look

The Significance of this Fluid Flow Regulator lies in its Patent Value and

Classification which is defined by five Categories and ranks between 4 & 5.

Level	Description	Percentage of all Inventions
1	Apparent Problem Solutions (Metaphor)	32%
2	Design / Product Improvement (Metaphor)	45%
3	Invention Inside of Paradigm	18%
4	Invention Outside of Paradigm	4%
5	True Discovery	1%

This may sound for some of you exaggerated - but it is not after taking a close look.

The decision if this Fluid Flow Regulator is an Invention outside of Paradigm or

a True Discovery should be in the eye of the beholder. However my conviction is that

this Invention is without any doubt at Level 4 because it doesn't meet any criteria

which allow the conclusion that this Invention is inside of Paradigm.

TERMINOLOGY

A Metaphor is the linking of two sets of concepts so one set of concepts is

understood in terms of another.

A Paradigm is the set of common beliefs and agreements shared between scientists

about how problems should be understood and addressed, also a class of all items

that can be substituted into the same position and/or a generally accepted

perspective of a particular discipline at a given time.

Let me know your Thoughts and Opinions

Economical Background of this Invention over the last 40 years

The Market success of many million of these Fluid Flow Regulators sold

and still distributed with climbing sales quantities, even the Patent

has expired years ago, proves that this invention is unique

and was never surpassed by anything better (Price, Accuracy, Reliability).

Brief Historical Summery

Starting with the Industrial Revolution in the 18^th Century in Europe and the United States

many mechanical patents were issued and many fell in these times in the category of True

Discoveries which is not surprising. However, after World War I and II significant Discoveries

became more and more rare and mechanical Inventions turned towards Patents based on

on existing prior art showing combinations of known Technology or Product Improvements.

Inventions Outside of Paradigm and True Discoveries are almost exclusively achieved by

the Chemical / Pharmatheutical Industries or are the results of modern Physics like

(Nano Technology)

Method for Producing Fluid Flow Regulators US Patent 4,632,791

Inventors: Wolf-Dieter Keppel, Chicago, USA

ReinHard C. Mannesmann, Herrsching, Germany

Assignee: ReinHard C. Mannesmann, Herrsching, Germany

Filed Jan.18, 1984

A Patent concerning a Method for plastic injecting mold manufacturing to

achieve higher part precision and an increase in mass production capability.

BRIEF DESCRIPTION

This Patent was based on the fact that the Plastic Injection Mold manufacturing was very

difficult and time consuming using an EDM Sinker to pre-burn the contour of the Profiled Core

and then grinding the contour with a pneumatic pencil grinder (equipped with a cylindrical

diamond pin) step by step larger, producing Samples on a Plastic Molding Machine after every

change, running Lab tests and then performing corresponding changes until the Regulation

Curve was completed to the required Flow Regulation Specifications. However, every molding

insert was unique and could not be duplicated. A 4-insert mold required that every insert had

to "developed" individually.

At this time the first "Wire EDM" Machines appeared on the market which had the capability

to cut a complex contour into a piece of pre-drilled metal based on programmable software.

Changing the injection mold design with Wire EDM was extremely time consuming compared

to the previous diamond grinding method. Performing any Profiled Core changes the process

sequence of program data changes, Wire EDM burning into a new blank, installing the burned

disk insert into an plastic injection mold, producing a sample and testing the result in a

Laboratory required the repetition of this above described R&D process over and over until

the profile in the disk delivered results to specification. However, ones the core profile

burned into the insert disk was perfect for production the big advantage of this method

was that the software data allowed to manufacture large numbers of duplicate insert disks.

This method made it possible to manufacture for large Production Molds which were

capable of manufacturing a large quantity of identical Flow Regulator in just one

Injection Molding Machine cycle which is very cost effective and recovered the R&D

cost in a short period of time.

The Patent Claims for this method were accepted in this time as an Invention even

Wire EDM was developed under the idea of precise metal part reproduction among

other applications.

A Patent of this kind is obviously an "Apparent Problem Solution" (Metaphor) and

falls in the Category 1 of the above table.

Inventor: Wolf-Dieter Keppel, Chicago, USA

Assignee: ABEO LLC. Omaha, NE

Filed: 2007

This Self-Drilling Rivet Gun was developed by me from the "Idea" to a finished first Prototype.

The first Prototype was a design based on a pneumatic / hydraulic principal. I utilized in my

R&D work Pro/Engineer (3D) and AutoCad (2D) Software.

The biggest problem to overcome was to engineer a mechanism which had the capability to

to provide a rotational movement for Drilling and then move into a position for Pulling a pop

rivet with a force of over 2000psi. Both function had to be combined utilizing parts which

were common for both functions and also provide a channel for the separated mandrel

to through the gun including the air motor and hydraulic assembly into a collector basket

for disposal. This Rivet Gun and an electrical version is intended for worldwide distribution.

Both versions contain numerous inventions which are partially included in the pending

Patent which can be viewed by clicking the Link below.

At this point I want to thank Mr. Jim Eggers (CEO) and Mr. Graig Wolf (CFO) from ABEO LLC.

located in Omaha, NE for hiring me as an Engineering Consultant to accomplish this complex

task. These Gentlemen not only financed this Project but also had the patience to wait for

optimized results which I delivered to them with great pride. See "My Credentials".

Please visit ABEO LLC's web site: http://abeollc.com/index.php and see a video of the

first successful Prototype test and other interesting information.

This Self-Drilling Rivet Gun is a very Versatile System: From light commercial work to heavy

industrial work, this component can be adapted for several applications:

Steel Framing
HVAC Duct Work
Architectural Sheet Metal
Structural Steel Framing
Automotive Assembly
Aircraft Manufacturing
Metal Building Fabrication

XENON

Medical - Dual Xenon Lamp Light Source for Endoscopy in Operating Rooms

Inventor: Wolf-Dieter Keppel, Chicago, USA

Unfortunately this is one of my inventions which never made it to the Patent Office because

my partner bailed out of his financial promise - and Inventors are usually poor.

This concept was great:

An Uninterruptible Operating Room Light Source

This new medical Light Source Invention was the first result of my Medical Device

Development program and was intended be used during Minimally Invasive Surgery when

Endoscopes (Laparoscopes, Arthroscopes, Cystoscopes etc.) are applied and

penetrate dark areas of the human body. In many cases the Abdominal Cavity which is

expanded by pressurized CO² Gas during Endoscopy to provide space during procedures.

A failure in Light supply to these instruments interrupts the surgical procedure until

the fiber optic light cable has to be plugged into a spare light source or until one is located.

This can be dangerous for the patient. During the time a new Light Source has to be

connected or brought over from another Operating Room uncontrolled bleeding may occur

or infectious fluid might reach other organs and cause later complications.

The Light Source which I developed avoids this problem. The light Source has 2 Xenon

light bulbs which face each other. One lamp was primary and always used. However, if this

primary bulb failed or even started to flicker a fiber optic cable directed to this primary lamp

transmitted the he light condition to a photo cell located on an electronic circuit board.

This photo cell gives a signal to an electronic processor chip which was programmed to trigger

a sequence of events: The secondary light bulb was supplied with power and turned a prism

by 90⁰redirecting the light flow from the primary lamp to the secondary lamp within a fraction

of a second. This was an ideal solution and well received by surgeons I talked to.

A man may die, nations may rise and fall, but an idea lives on

Genius is one percent inspiration, and ninety-nine percent perspiration.

The profit of great ideas comes when you turn them into reality.

Necessity is the mother of invention, it is true - but it's father is creativity, and knowledge is the midwife.

Imagination is the beginning of creation.

The man with a new idea is a crank - until the idea succeeds.

Creativity is thinking up new things. Innovation is doing new things.

Inventing is a combination of brains and materials. The more brains you use, the less material you need.

I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success

Creation is a drug I can’t live without
