DuPont Typar Geotextile Material
DuPont Typar is a nonwoven geotextile fabric
composed of thermally bonded continuous
polypropylene filaments. The fibre extrusion
process produces thousands of superfine
continuous filaments, which pass through a
DuPont patented “pre-stretch” stage. The
superfine tough filaments are directionally
oriented producing a fibre web sheet that is
then thermally and mechanically bonded.

H o w T y p a r G e o t e x t i le W o r k
• Failure of a drainage system is caused by the intermixing
of the free-draining aggregate materials with the
subgrade soil, which leads to clogging of the aggregate.
• TYPAR Geotextiles separate soil from the filter aggregate
stone, which minimizes intermixing, helping to maintain
the integrity of the drain.
• TYPAR Geotextile’s tensile strength, puncture resistance,
tear resistance, opening size and hydraulic properties
make it an ideal filter fabric for drainage systems.

Filtration And / or Drainage
Filtration: The geosynthetic acts similar to a sand filter by allowing water to
move through the soil while retaining all upstream soil particles.
Function of Geotextile

Function of Geotextile
Filtration And / or Drainage

US Patented ReGenX Generator, ReGen-X Quatum Motor EV Regenerative Accelerati...Thane Heins NOBEL PRIZE WINNING ENERGY RESEARCHER

��

Preface: The ReGenX Generator innovation operates with a US Patented Frequency Dependent Load Current Delay which delays the creation and storage of created Electromagnetic Field Energy around the exterior of the generator coil. The result is the created and Time Delayed Electromagnetic Field Energy performs any magnitude of Positive Electro-Mechanical Work at infinite efficiency on the generator's Rotating Magnetic Field, increasing its Kinetic Energy and increasing the Kinetic Energy of an EV or ICE Vehicle to any magnitude without requiring any Externally Supplied Input Energy. In Electricity Generation applications the ReGenX Generator innovation now allows all electricity to be generated at infinite efficiency requiring zero Input Energy, zero Input Energy Cost, while producing zero Greenhouse Gas Emissions, zero Air Pollution and zero Nuclear Waste during the Electricity Generation Phase. In Electric Motor operation the ReGen-X Quantum Motor now allows any magnitude of Work to be performed with zero Electric Input Energy. Demonstration Protocol: The demonstration protocol involves three prototypes; 1. Protytpe #1, demonstrates the ReGenX Generator's Load Current Time Delay when compared to the instantaneous Load Current Sine Wave for a Conventional Generator Coil. 2. In the Conventional Faraday Generator operation the created Electromagnetic Field Energy performs Negative Work at infinite efficiency and it reduces the Kinetic Energy of the system. 3. The Magnitude of the Negative Work / System Kinetic Energy Reduction (in Joules) is equal to the Magnitude of the created Electromagnetic Field Energy (also in Joules). 4. When the Conventional Faraday Generator is placed On-Load, Negative Work is performed and the speed of the system decreases according to Lenz's Law of Induction. 5. In order to maintain the System Speed and the Electric Power magnitude to the Loads, additional Input Power must be supplied to the Prime Mover and additional Mechanical Input Power must be supplied to the Generator's Drive Shaft. 6. For example, if 100 Watts of Electric Power is delivered to the Load by the Faraday Generator, an additional >100 Watts of Mechanical Input Power must be supplied to the Generator's Drive Shaft by the Prime Mover. 7. If 1 MW of Electric Power is delivered to the Load by the Faraday Generator, an additional >1 MW Watts of Mechanical Input Power must be supplied to the Generator's Drive Shaft by the Prime Mover. 8. Generally speaking the ratio is 2 Watts of Mechanical Input Power to every 1 Watt of Electric Output Power generated. 9. The increase in Drive Shaft Mechanical Input Power is provided by the Prime Mover and the Input Energy Source which powers the Prime Mover. 10. In the Heins ReGenX Generator operation the created and Time Delayed Electromagnetic Field Energy performs Positive Work at infinite efficiency and it increases the Kinetic Energy of the system.

Designing Flex and Rigid-Flex PCBs to Prevent FailureEpec Engineered Technologies

��

Flex and rigid-flex printed circuit boards (PCBs) can be considered at the basic level some of the most complex PCBs in the industry. With that in mind, it’s incredibly easy to make a mistake, to leave something out, or to create a design that was doomed from the start. Such design failures can end up leading to an eventual failure by delamination, short circuits, damage to the flex portions, and many other things. The easiest way to circumvent these is to start at the beginning, to design with preventing failure in mind rather than trying to fix existing designs to accommodate for problems. In this webinar, we cover how to design flex and rigid-flex PCBs with failure prevention in mind to save time, money, and headaches, and what failure can look like. For more information on our flex and rigid-flex PCB solutions, visit https://www.epectec.com/flex.

8. DuPont Typar Geotextile Material DuPont Typar is a nonwoven geotextile fabric composed of thermally bonded continuous polypropylene filaments. The fibre extrusion process produces thousands of superfine continuous filaments, which pass through a DuPont patented “pre-stretch” stage. The superfine tough filaments are directionally oriented producing a fibre web sheet that is then thermally and mechanically bonded.

9. H o w T y p a r G e o t e x t i le W o r k • Failure of a drainage system is caused by the intermixing of the free-draining aggregate materials with the subgrade soil, which leads to clogging of the aggregate. • TYPAR Geotextiles separate soil from the filter aggregate stone, which minimizes intermixing, helping to maintain the integrity of the drain. • TYPAR Geotextile’s tensile strength, puncture resistance, tear resistance, opening size and hydraulic properties make it an ideal filter fabric for drainage systems.

10. Function of Geotextile

11. Filtration And / or Drainage Filtration: The geosynthetic acts similar to a sand filter by allowing water to move through the soil while retaining all upstream soil particles. Function of Geotextile

12. Function of Geotextile Filtration And / or Drainage Filtration: Primarily geotextile holds the soil particle in place and allow the water to filter through without hydrostatic pressure build up.
