    ROCKET REACHES 100 MI ALTITUDE
    July 30, 1946 - White Sands, NM, USA

    For the first time an altitude of 100 mi (167 km) was reached by a test rocket. It was a V-2 rocket (No. 9), fueled with alcohol and liquid oxygen launched at White Sands, NM. This test had the first separation of nose cone. During World War II, the nose cone held a German warhead containing almost a ton of explosives. At White Sands, the Army invited government agencies and universities to use the nose cone's 20 cubic feet of space for scientific research, up to 2,000 pounds of scientific equipment, such as cameras, sensors, and on-board experiments, were carried aloft on each flight.

    MAHLON LOOMIS RECEIVED A PATENT
    July 30, 1872

    For a new and Improved Mode of Telegraphing and of Generating Light, Heat, and Motive Power' (U.S.No. 129,971). In 1865, Loomis had transmitted wireless signals between two mountains in Virginia using two kites flown 18 miles apart, each carrying a 600 foot wire from the ground. When he interrupted the flow of electricity from the atmosphere, through the wire, to an earth ground, a galvonometer on the other kite's wire measured a current change. He also noted dark clouds passing over his apparatus causing too much electricity to be collected by the aerials...causing him to shut down operations. This wireless communication took place many years before Marconi's experiments.

    about Eyesight Myth and Fact

    Myth: Staring at a computer screen all day is harmful to the eyes. Fact: Spending the day staring at a screen can tire or strain your eyes, but it will not hurt them. Make sure lighting doesn't create a glare on your screen. When spending long periods at your keyboard, take a break now and then to rest your eyes to reduce fatigue. Also, don't forget to blink. Your eyes need to stay lubricated to feel comfortable.

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.
