    ARTIFICIAL SWEETENER PATENT ISSUED
    January 27, 1970 - U.S. Food and Drug Administration

    James M. Schlatter received a patent for “Peptide Sweetening Agents” (U.S. No. 3,492,131), an invention which eventually led to the marketing of aspartame under the name NutraSweet. The patent was filed 18 Apr 1966, assigned to his employer, G.D. Searle & Co. In Dec 1965, a few months before filing, he had accidentally discovered the first example of such compounds. To pick up a paper, he had licked his finger. He tasted an unexpectedly sweet trace of a substance that had, he realized, earlier splashed onto the outside of a flask he had handled. It contained L-aspartyl-L-phenylalnine methyl ester. After development and much scrutiny of the testing of aspartame, the U.S. Food and Drug Administration approved it (22 Oct 1981) with many permitted uses as a food sweetener.

    EINSTEIN ADDRESS
    January 27, 1921 - Prussian Academy of Sciences, Berlin

    Albert Einstein suggested the possibility of measuring the universe, which startled the audience, with his address Geometry and Expansion given at the Prussian Academy of Sciences in Berlin. Applying certain results of the relativity theory, he came to the conclusion that if the real velocities of the stars (as could be actually measured) were less than the calculated velocities, then it would prove that the real gravitations' great distances were smaller than the gravitational distances demanded by the law of Newton. From such divergence, the finiteness of the universe could be proved indirectly, and it would even permit the estimation of its size.

  • The wealth of the nation

    "...The wealth of the nation is its air, water, soil, forests, minerals, rivers, lakes, oceans, scenic beauty, wildlife habitats and biodiversity that'as all there is. That'as the whole economy. That'as where all the economic activity and jobs come from. These biological systems are the sustaining wealth of the world...."

    "...Until a man duplicates a blade of grass, Nature can laugh at his so-called scientific knowledge. Remedies from chemicals will never stand in favorable comparison with the products of Nature, the living cell of a plant, the final result of the rays of the sun, the mother of all life...."

    More vehicles are stolen on New Year's Day than any other holiday throughout the year. (So does that mean thieves are having their last fling before changing their ways or are they trying for a big score to start the New Year?) Salary

An electric fuse is a current interrupting device that protects an electrical circuit. It is mounted within the circuit and is activated when excess current, which could damage the circuit, enters the circuit.

Fuses are used generally as a conduit between an electrical power source, and an electrical component arranged in an electrical circuit. They are designed for one time use only, hence, once it shuts down a device, it must be replaced.

Electrical fuses are part of the electrical systems in cars, trucks, motorcycles, boats and other type of vehicles. They function to stop the flow of electricity to a certain component of the system by making an open circuit, arising from an unsafe electrical condition.

There are three basic types of fuses. These are the slow blow, the fast acting fuses and the very fast acting fuses. The other terms for slow blow are time lag and time delay fuses or the TL for time delay fuses.

A major type of time delay fuse is the dual-element. It consists of a short circuit strip, spring connection and soldered joint. During current overload, the soldered joints get hot and start to melt. Then the spring shears the junction loose.

During short circuit, the short circuit element works to open the circuit. The slow-blow electric fuse allows a temporary and harmless rush of current to move into the circuit without breaking open. Rather it opens on the sustained overloads and short circuits. Slow-blow fuses are ideal for circuits with a transient surge of power. This lets current to continue flowing into the circuit at close to the fuse rating. This prevents the fuse from breaking open and having to be replaced. Usually, they are rated between 125% and 150% of the circuits? full load amperes.

If you are looking for fuses for home use, the TL fuses are the best choice. Not only are they medium duty; but they are the recommended fuses for home uses. The TL fuses uses an Edison base, while the SL fuses uses a Rejection base.

The fast acting fuses are also called S and T fuses. They are heavy duty time delay fuses used for circuits that have critical or high motor loads. An S or T electrical fuse is also used for circuits that have motors which cycle on and off more often like the sump pump. It features longer time delay than the TL fuse. The difference between S and T fuses are their bases. The T fuse uses an Edison base, while the S fuse uses a Rejection base.

The very fast acting fuses are also called mini breakers. They are able to convert a fuse to a circuit breaker. A mini breaker electric fuse is a retrofit circuit breaker fuse that screws into an Edison base fuse socket. It is excellent as it converts a fuse into a push-button circuit breaker.

The mini breaker electric fuse has a little push button which pops out. Whenever the circuit is overloaded, you just need to reset the fuse by pushing a button. These types of fuses are designed to meet your needs.
