High-Flow Lift Pump

In fighting wildfires, and in many other applications, there is a need to lift water a few feet, say from a creek or river, to fill a header tank or mobile water tender. Particularly in firefighting, turnaround time is what measures success at the end of the day.

The current invention comprises an axial flow impeller pump section located at the inlet end of the transfer hose, a power head at the flex-fitting located near the destination (tank or truck), and a flexible drive shaft running inside the transfer hose. Sections of transfer hose may be daisy-chained, with the internal drive shafts automatically coupling together as the hose is assembled.

Prototypes have been built and successfully ...

One of the biggest problems with any device that needs an electric motor is the faster a motor turns and the more torque that is required, the more current and/or voltage is required to run it which limits the time a motor can run from a stored energy source like a battery. My motor modification enables a motor to run at variable speeds and produce a high torque while maintaining a fixed current and voltage.

By extending the time a motor can run from a battery will enable any device needing a motor to run with fewer battery changes and longer intervals needed for recharging the battery. Because the motor runs, using milliamps and low voltage, a solar cell ...

Mag-Lift Handle
Problem: When moving or lifting furniture and appliance items, difficulty occurs when there is no handle on a flat metal surface. The item may not be too heavy to lift, just awkward. Some items, such as file cabinets, have sharp metal edges in areas use to lift the cabinet; many hands have been cut moving these. A dryer, washer, cooking range, and a refrigerator are not too heavy for two men to lift but, with no handles the job becomes tricky.
Solution: The “Mag-Lift” is a portable electro-magnet enabling it to become a ready handle, which can be placed on any flat ferrous metal object. Powered by conventional portable tool batteries; the batteries are operational in series ...

The Problem
Friction is the world's single biggest waste of energy. New polymeric and nano-composite bearing material “recipes” promise substantial friction reducing solutions. However, their development and application are often hindered by current tribological (the study of lubrication, friction and wear) test systems, driven by three recognized issues:
• Long test time: Due to measurement limitations, it can take a test duration over 200 hours to assess tribological properties at a single pressure (P) and sliding velocity (V) combination.
• A flawed assumption in application models concerning wear rates being proportional to a constant PV. Long test time makes gathering the multiple PV combination data for a better model a commercial challenge.
• Single PV test capabilities of ...

This design presents a method for containing oil from a subsea oil blowout. An apparatus constructed from this design will mitigate the spread of oil slicks from subsea oil blowouts, with the benefit of allowing oil exploration to proceed with diminished risk of environmental damage. The method has particular application where coastal wetlands or other delicate ecosystems could be damaged by an oil spill. There currently appears to be no alternative method for containing the oil from such blowouts. The apparatus has market potential in basins subject to offshore oil exploration where deepwater rigs are active.

The design consists of two parts. The first part is a conical-shaped oil trap that is assembled in place just under the ocean ...

Power electronics as the controllers of speed are used for the velocity control of motors in the petroleum operations.
Because the extraction pumps are at extreme depths is required that this equipment is fed by an electrical system of median tension.
The transformer, connected to systems that speed controllers use, are exposed to a train of pulses with a front tension (dv/dt) extremely high and with frequency of repetition also relatively high, which increases the efforts in the dielectric of the windings, as much of the primary winding, that in the present case is of low tension, like in the secondary winding which is of median tension.
With the geometric data and of construction of a typical transformer ...

Relying on the good chemical and temperature stability, optical properties, biocompatibility, sterilizing ability and the possibility to be cleaned easily of glasses, micro-structured glass parts are applied in many fields with billions of dolloars potential market. However, the current micro glass parts producing technologies can not realize the mass low-cost production of micro glass parts (2D area 99%) and rapid processing time ( the presented fabrication concept is proposed and realized on the base of a desk top glass micro injection molding machine schematically illustrated as Fig.1. This device will comprise of four main parts, which are melting/storage unit, dosing/injection unit, mould assembling/clamping unit, variotherm unit and vacuum assistant unit. The process cycle can be described as: firstly, glass ...

Our micro robot – patent approved - is 5 x 5 mm small and holds a diamond. It moves with sub-micrometer precision in 3D space. The diamond drills holes, polishes mirrors, grinds lenses, cuts channels and mills 3-D parts of any shape. This creates solid parts with a precision of +/- 100 nano meter. The micro robot is a micro milling and boring machine and has the size of a coffee machine.
Produced parts are made of silicon, aluminum, steel, aluminum-oxide or plastics. Replace the diamond with a pneumatic gripper and you can pick micro parts. Replace it with a glue dispenser and you can assemble them together. This allows to further miniaturize tech products and even create ...

MODERN DRILLING CONCEPT
This concept drilling method is a great improvement over the present technology.
Currently while drilling takes place if there is a leak it will flow directly into the sea causing environment pollution.
This concept as shown in the diagram has two dome shaped protection walls made of concrete or hard metal. The outer layer keeps sea water out. The inner layer collects any leakage and when the drill is being removed oil may escape into the outer layer, in which case the motor pump inside the inner layer will pump it back into the inner layer.
This also helps the workers repair faster beneath the sea and every time there is any leakage during drilling the ...

We need the right filter in every sphere of life, have a dream for a universal filter which is user & environmently friendly, applicable everywhere changing minimum parts or consumables to reduced inventory, variable of filtration, finer to faster, helps worker to put valuable time and attention to productivity, hygienic system ensures health of valuable workforce, operation can be seen through transparent cover, open it like a car bonnet for smooth operation and handling, can be moved or stopped with wheel and stopper.
This is compact, user and environment-friendly, safe due to no sharp edges, UV lamp inside prevents bacteria generation, uses very negligible power, practically no attendant required, less inventory for parts and consumable, Dual stage filter ensures finer ...
