Introduction The concepts that I would like to present are a thermal-magnetic motor and a planetary transmission that operates off a set of calipers, instead of a band. I was first introduced to the thermal-magnetic motor in 1980. A thermal-magnetic motor works off the Currie Point of metals. All ferrous metals lose their ability to hold a magnetic field at a certain temperature. Different metals lose theirs at different temperatures. Nickel has a very low temperature and can still hold its shape, so it is the metal I choose. The first experiments were conducted using a metal that was used in old speedometers, as friction heated a magnetic coupling, the bond would slip and compensate the reading. This was ...

The Solar Forge is comprised of a large parabola section reflector, a carriage, and a target. The parabola concentrates sunlight, the carriage allows the parabola to track the sun, and the target makes the resulting heat available for a practical purpose. The Solar Forge concentrates enough power to be useful for small commercial processes in sunny climes, particularly in developing nations.

Application

In developing nations the Solar Forge can be used as a small industrial power source to forge recycled metal. As it happens, it is impossible to manufacture the springs or drive shaft of any car out of bad steel. It is a shame to let such good material be mixed in with scrap iron and not forge ...

The third generation modular Universal Flight Controller (UFC-3) was designed for the high end amateur high power rocketeer, primarily flights above 60,000' and for FAA Class III Rocketry.

It is the only system available the offers over a dozen different modules and can start with a single module for minimal flight control to an eight module (network expandable) system with 200 MHz. CPU, 256 MB flight log memory, high altitude altimeter, dual accelerometers, long range telemetry (uplink and downlink), GPS (including COCOM limit removal), 3-Axis Inertial Sensor, up to 32 16-bit ADC channels, external and internal powered Pyro Modules, Battery Modules and the most recent Open System Developers Module that allows low cost development of custom ...

This proposal relates to conceptual design of "valved two stroke engine with extended expansion". In a four stroke engine, power stroke occurs once in a two rotation whereas in a two stroke power stroke occurs once in each rotation. Theoretically a two stroke engine produces double the power of four stroke engine .Due to absence of valves in 2 stroke engine, some part of the fresh charge inducted leaves out through exhaust .This causes loss of mileage and Hydrocarbon emission .The proposed engine has Transfer valve which prevents such carry over and at the same time power stroke occurs for each rotation. The "extended expansion" refers that the pressure at the end of power stroke is brought nearly to ...

Imagine having a ball with an input shaft and an output shaft that you can move to almost any position and still supply a constant power to the output shaft, even while moving.

It's easy to find a 90 degree gearbox. Such a gearbox can be mounted at any angle, but is stationary. Then there is the universal joint. A universal joint works well when one of the shafts may be move, but not too far. The coupling only works well when the shafts are almost positioned in a straight line.

The Variable Angle Gearbox (VAG) can be a replacement to a gearbox, a u-joint, or a coupling. It isolates the normal vibrations of a drive shaft from the ...

Variable ratio chain drives (derailleurs) are extremely efficient, but suffer from several problems:

1. They should not be shifted under load.
2. They should not be shifted while stopped.
3. The chain is side loaded for most gear combinations, limiting the useful combinations.
4. They are subject to jamming caused by the chain wedging between the gears.

This concept addresses those problems by using rings of retractable, bistable teeth mounted in each of a pair of wheels. The gear ratio is changed by extending/retracting the rings of teeth to choose an appropriate combination. The teeth are moved by a shifter fork (light green) operating in the portion of the wheel where the chain is not engaged. The ...

At present ,the high demand of dry food is very high and the process used commonly becomes very expensive to supply her involving high costs in machinery and qualified personnel.
The w-select is a technological tool that it allows at the companies to improve your productive processes optimizing time, resources and more important, reducing costs of a substantial way.

This innovative process of selection of dry food is realized by means of filtration by vibration of a piston. The such dry food as beans, lentils, vetches between others, they are fed thanks to the effect of the gravity by the tray of supply that contains an electromagnet to gather the metallic particles that the initial product could contain ...

Water Mortar Currently fire suppression systems use water at a flow rate of 750 to 1500 gpm. This causes alot of atomization, as a 1500 gpm flow is traveling at 120 mph, as it leaves a 1in nozzle. In a hot fire, most of this water is turned into steam, and goes into the atmosphere. The water mortar sends a package of water to the fire, that explodes directly at the source. The mortar "shell" consists of an outer shell(either heat deteriorating, or charge deteriorating), inner, smaller packages of water, and a charge (or pressurization of the entire package) to disburse the water balloons. Detonating the charge could be by heat sensitive skin, that ruptures at a given temperature ...

The Problem:
Diesel engines were invented more than one hundred years ago. Continuous refinements have made diesels cleaner, quieter and more powerful. Nevertheless, the basic principles of operation and overall design remain unchanged. For this reason, diesel engines retain several shortcomings they have always had.

Diesels are noisy and hard to start in cold weather. The best engines have a peak efficiency of 40% and this is usually very close to full power. The delivered efficiency is less because engines do not normally run at full power. The YankeeDiesel (www.yankeediesel.com) was designed to overcome these problems.

The Solution:
?Diesel engines get their power from combustion gases pushing a piston. The moving piston rotates the crankshaft. But if you keep ...

The invention is meant to replace the optical zoom.

PROBLEM:
Optical zoom is an expensive, heavy and complicated device with over 100 parts. Some other drawbacks are: long development times, very complex optical calculations, the large number of the lenses and it can't be miniaturized. Compared to the high costs, the optical quality is rather poor, especially for big magnification ranges. Also for the zoom with variable lenses and the “digital” zoom the quality decreases dramatically with magnification range increasing.

SOLUTION:
Combination of discrete magnification changers (MC) like e. g. Galilei MC with a zoom to fill the gap between the discrete magnification stages. To save space and resources it preferably will be zoom with variable lenses or “digital” ...
